STYLE="font-family:Times New Roman" SIZE="2"><B>Regulation </B></FONT></P> <P STYLE="margin-top:6px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">Unitil is subject to comprehensive regulation by federal and state regulatory
authorities. Unitil and its subsidiaries are subject to regulation as a holding company system by the FERC under the Energy Policy Act of 2005 with regard to certain bookkeeping, accounting and reporting requirements. Unitil&#146;s utility
operations related to wholesale and interstate energy business activities are also regulated by the FERC. Unitil&#146;s distribution utilities are subject to regulation by the applicable state public utility commissions, with regard to their rates,
issuance of securities and other accounting and operational matters: Unitil Energy is subject to regulation by the New Hampshire Public Utilities Commission (NHPUC); Fitchburg is subject to regulation by the Massachusetts Department of Public
Utilities (MDPU); and Northern Utilities is regulated by the NHPUC and the Maine Public Utilities Commission (MPUC). Granite State, Unitil&#146;s interstate natural gas transmission pipeline, is subject to regulation by the FERC with regard to its
rates and operations. Because Unitil&#146;s primary operations are subject to rate regulation, the regulatory treatment of various matters could significantly affect the Company&#146;s operations and financial position. </FONT></P>
<P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">Unitil&#146;s distribution utilities deliver electricity and/or natural gas to all customers in their service territory, at rates established under cost
of service regulation. Under this regulatory structure, Unitil&#146;s distribution utilities recover the cost of providing distribution service to their customers based on a historical test year, and earn a return on their capital investment in
utility assets. In addition, the Company&#146;s distribution utilities and its natural gas transmission pipeline company may also recover certain base rate costs, including capital project spending and enhanced reliability and vegetation management
programs, through annual step adjustments and cost tracker rate mechanisms. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">Fitchburg is subject to revenue decoupling. Revenue decoupling is
the term given to the elimination of the dependency of a utility&#146;s distribution revenue on the volume of electricity or natural gas sales. The difference between distribution revenue amounts billed to customers and the targeted revenue
decoupling amounts is recognized as an increase or a decrease in Accrued Revenue which forms the basis for resetting rates for future cash recoveries from, or credits to, customers. These revenue decoupling targets may be adjusted as a result of
rate cases and other authorized adjustments that the Company files with the MDPU. The Company estimates that revenue decoupling applies to approximately 27% and 11% of Unitil&#146;s total annual electric and natural gas sales volumes, respectively.

the targeted area the ability to pay a rate surcharge, instead of a large upfront payment or capital contribution to connect to the natural gas delivery system. The initial pilot of the TAB program was approved for the City of Saco, and is being
built out over a period of three years, with the potential to add 1,000 new customers and approximately $1&nbsp;million in annual distribution revenue in the Saco area. The second TAB program was approved for the Town of Sanford, and has the

accompanying unaudited Consolidated Financial Statements and the accompanying Notes to unaudited Consolidated Financial Statements included in Part I, Item&nbsp;1 of this report, which are prepared in accordance with accounting principles generally
accepted in the United States of America (GAAP). </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">The Company&#146;s results of operations reflect the seasonal nature of the natural gas
business. Annual gas revenues are substantially realized during the heating season as a result of higher sales of natural gas due to cold weather. Accordingly, the results of operations are historically most favorable in the first and fourth
quarters. Fluctuations in seasonal weather conditions may have a significant effect on the result of operations. Sales of electricity are generally less sensitive to weather than natural gas sales, but may also be affected by the weather conditions
in both the winter and summer seasons. Also, as a result of recent rate cases, the Company&#146;s natural gas sales margins are derived from a higher percentage of fixed billing components, including customer charges. Therefore, natural gas revenues
and margin will be less affected by the seasonal nature of the natural gas business. In addition, as discussed above, approximately 27% and 11% of the Company&#146;s total annual electric and natural gas sales volumes, respectively, are decoupled
and changes in sales to existing customers do not affect sales margin. </FONT></P> <P STYLE="margin-top:18px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2"><B>Earnings Overview </B></FONT></P>

in 2016. The decrease in earnings for the third quarter of 2017 was driven by lower electric sales margins, reflecting milder summer weather in 2017 compared to the same period in 2016 and higher operating expenses, partially offset by higher gas
sales margins and customer growth. The increase in earnings for the first nine months of 2017 was driven by higher natural gas and electric sales margins and customer growth. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT

 <P STYLE="margin-top:0px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">The Company analyzes operating results using Gas Sales Margin, a non-GAAP measure. Gas Sales Margin is
calculated as Total Gas Operating Revenue less Cost of Gas Sales. The Company believes Gas Sales Margin is an important measure to analyze profitability because the approved cost of sales are tracked and reconciled costs that are passed through
directly to the customer, resulting in an equal and offsetting amount reflected in Total Gas Operating Revenue. Sales margin can be reconciled to Operating Income, a GAAP measure, by including Operation and Maintenance, Depreciation and Amortization
and Taxes Other Than Income Taxes for each segment in the analysis. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">Natural gas sales margins were $16.8 million and $75.3 million in the
three and nine months ended September&nbsp;30, 2017, respectively, resulting in increases of $0.8 million and $3.6 million, respectively, compared to the same periods in 2016. Gas sales margin in the third quarter was positively affected by higher
natural gas distribution rates of $0.6 million and higher sales volume and customer growth of $0.2 million. For the nine month period, gas sales margin was positively affected by higher natural gas distribution rates of $2.3 million and higher sales
volume and customer growth of $1.3 million. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">The increases in Total Gas Operating Revenues of $3.0 million and $7.8 million in the three and

usage, partially offset by customer growth. Based on weather data collected in the Company&#146;s electric service areas, there were 32% fewer CDD in the third quarter of 2017 compared to the same period in 2016. As of September&nbsp;30, 2017, the
number of total electric customers served has increased by approximately 1,000 in the last twelve months. As previously discussed, sales margins derived from decoupled unit sales (representing approximately 27% of total annual kWh sales volume) are
not sensitive to changes in electric kWh sales. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">The following table details total kWh sales for the three and nine months ended

calculated as Total Electric Operating Revenues less Cost of Electric Sales. The Company believes Electric Sales Margin is an important measure to analyze profitability because the approved cost of sales are tracked and reconciled costs that are
passed through directly to the customer resulting in an equal and offsetting amount reflected in Total Electric Operating Revenues. Sales margin can be reconciled to Operating Income, a GAAP measure, by including Operation and Maintenance,
Depreciation and Amortization and Taxes Other Than Income Taxes for each segment in the analysis. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">Electric sales margins were $24.8 million
and $70.1 million in the three and nine months ended September&nbsp;30, 2017, respectively, resulting in a decrease of $0.8 million and an increase of $4.0 million, respectively, compared to the same periods in 2016. Electric sales margin in the
third quarter was negatively affected by lower sales volume due to milder weather of $0.8 million, offset by higher distribution rates of $0.8 million and customer growth of $0.1 million. Also, the Company recognized an adjustment of $0.9 million to
true up the collection of transmission revenues in the third quarter of 2016. For the nine month period, electric sales margin was positively affected by higher electric distribution rates of $4.4 million and customer growth of $0.4 million,
partially offset by lower sales volumes due to the impact of milder summer weather of $0.8 million. The higher electric distribution rates in the nine month period include $1.4 million in higher electric sales margin reflecting the reconciliation of
permanent rates to temporary rates, which were previously provided in Unitil Energy&#146;s distribution base rate case. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">The increase in Total

higher vegetation management costs, which are recovered in reconciling rate adjustment mechanisms and reflected in electric sales margin, higher regulatory costs of $0.7 million, higher system maintenance costs of $1.1 million. </FONT></P>

three month period reflects lower amortization of major storm costs which were incurred in prior years and deferred for rate recovery for periods up to eight years. The increase in the nine month period reflects higher depreciation on higher utility

expense is mainly comprised of interest on long-term debt and short-term borrowings. In addition, certain reconciling rate mechanisms used by the Company&#146;s distribution operating utilities give rise to regulatory assets and regulatory
liabilities on which interest is calculated. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">Unitil&#146;s utility subsidiaries operate a number of reconciling rate adjustment mechanisms to
recover specifically identified costs on a pass through basis. These reconciling rate adjustment mechanisms track costs and revenue on a monthly basis. In any given month, this tracking and reconciling process will produce either an under-collected
or an over-collected balance of costs. In accordance with the distribution utilities&#146; rate tariffs, interest is accrued on these balances and will produce either interest income or interest expense. Consistent with regulatory precedent,
interest income is recorded on an under-collection of costs which creates a regulatory asset to be recovered in future periods when rates are reset. Interest expense is recorded on an over-collection of costs, which creates a regulatory liability to
be refunded in future periods when rates are reset. </FONT></P>

<P STYLE="margin-top:6px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">Unitil requires capital to fund utility plant additions, working capital and other utility expenditures recovered in subsequent periods through regulated
rates. The capital necessary to meet these requirements is derived primarily from internally-generated funds, which consist of cash flows from operating activities. The Company initially supplements internally-generated funds through short-term bank
borrowings, as needed, under its unsecured revolving Credit Facility. Periodically, the Company replaces portions of its short-term debt with long-term financings more closely matched to the long-term nature of its utility assets. Additionally, from
time to time, the Company has accessed the public capital markets through public offerings of equity securities. The Company&#146;s utility operations are seasonal in nature and are therefore subject to seasonal fluctuations in cash flows. The
amount, type and timing of any future financing will vary from year to year based on capital needs and maturity or redemptions of securities. </FONT></P>
<P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">The Company and its subsidiaries are individually and collectively members of the Unitil Cash Pool (the &#147;Cash Pool&#148;). The Cash Pool is the
financing vehicle for day-to-day cash borrowing and investing. The Cash Pool allows for an efficient exchange of cash among the Company and its subsidiaries. The interest rates charged to the subsidiaries for borrowing from the Cash Pool are based
on actual interest costs from lenders under the Company&#146;s revolving Credit Facility. At September&nbsp;30, 2017,&nbsp;September&nbsp;30, 2016 and December&nbsp;31, 2016, the Company and all of its subsidiaries were in compliance with the
regulatory requirements to participate in the Cash Pool. </FONT></P>

interest per annum equal to one-month London Interbank Offered Rate (LIBOR) plus 1.25%. Provided there is no event of default under the Credit Facility, the Company may on a one-time basis request an increase in the aggregate commitments under the

assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. In
making those estimates and assumptions, the Company is sometimes required to make difficult, subjective and/or complex judgments about the impact of matters that are inherently uncertain and for which different estimates that could reasonably have
been used could have resulted in material differences in its financial statements. If actual results were to differ significantly from those estimates, assumptions and judgment, the financial position of the Company could be materially affected and
the results of operations of the Company could be materially different than reported. For a complete discussion of the Company&#146;s significant accounting policies, refer to the Note 1 to the Consolidated Financial Statements in the Company&#146;s

STYLE="font-family:Times New Roman" SIZE="2">A fifth utility subsidiary, Unitil Power, formerly functioned as the full requirements wholesale power supply provider for Unitil Energy. In connection with the implementation of electric industry
restructuring in New Hampshire, Unitil Power ceased being the wholesale supplier of Unitil Energy on May&nbsp;1, 2003 and divested of its long-term power supply contracts through the sale of the entitlements to the electricity associated with
various electric power supply contracts it had acquired to serve Unitil Energy&#146;s customers. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">Unitil also has three other wholly-owned

management, all adjustments considered necessary for a fair presentation have been included and are of a normal and recurring nature. The results of operations for the three and nine months ended
September&nbsp;30, 2017 are not necessarily indicative of results to be expected for the year ending December&nbsp;31, 2017. For further information, please refer to Note 1 of Part II to the Consolidated Financial Statements &#150; &#147;Summary of
Significant Accounting Policies&#148; of the Company&#146;s Form 10-K for the year ended December&nbsp;31, 2016, as filed with the Securities and Exchange Commission (SEC) on February&nbsp;2, 2017, for a description of the Company&#146;s Basis of
Presentation. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2"><B>Income Taxes &#150;</B> The Company is subject to Federal and State income taxes as well as various other business taxes.
This process involves estimating the Company&#146;s current tax liabilities as well as assessing temporary and permanent differences resulting from the timing of the deductions of expenses and recognition of taxable income for tax and book
accounting purposes. These temporary differences result in deferred tax assets and liabilities, which are included in the Company&#146;s Consolidated Balance Sheets. The Company accounts for income tax assets, liabilities and expenses in accordance
with the Financial Accounting Standards Board (FASB) Codification guidance on Income Taxes. The Company classifies penalty and interest expense related to income tax liabilities as income tax expense and interest expense, respectively, in the
Consolidated Statements of Earnings. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">Provisions for income taxes are calculated in each of the jurisdictions in which the Company operates
for each period for which a statement of earnings is presented. The Company accounts for income taxes in accordance with the FASB Codification guidance on Income Taxes, which requires an asset and liability approach for the financial accounting and
reporting of income taxes. Significant judgments and estimates are required in determining the current and deferred tax assets and liabilities. The Company&#146;s current and deferred tax assets and liabilities reflect its best assessment of
estimated future taxes to be paid. In accordance with the FASB Codification, the Company periodically assesses the realization of its deferred tax assets and liabilities and adjusts the income tax provision, the current tax liability and deferred
taxes in the period in which the facts and circumstances which gave rise to the revision become known. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2"><B>Cash and Cash Equivalents
&#150;</B> Cash and Cash Equivalents include all cash and cash equivalents to which the Company has legal title. Cash equivalents include short-term investments with original maturities of three months or less and interest bearing deposits. The
Company&#146;s cash and cash equivalents are held at financial institutions and at times may exceed federally insured limits. The Company has not experienced any losses in such accounts. Under the Independent System Operator&#151;New England
(ISO-NE) Financial Assurance Policy (Policy), Unitil&#146;s subsidiaries Unitil Energy, Fitchburg and Unitil Power are required to provide assurance of their ability to satisfy their obligations to ISO-NE. Under this Policy, Unitil&#146;s
subsidiaries provide cash deposits covering approximately 2-1/2 months of outstanding obligations, less credit amounts that are based on the Company&#146;s credit rating. As of September&nbsp;30, 2017,&nbsp;September&nbsp;30, 2016 and
December&nbsp;31, 2016, the Unitil subsidiaries had deposited $4.8 million, $3.5 million and $2.8 million, respectively to satisfy their ISO-NE obligations. In addition, Northern Utilities has cash margin deposits to satisfy requirements for its
natural gas hedging program. There were no cash margin deposits at Northern Utilities as of September&nbsp;30, 2017,&nbsp;September&nbsp;30, 2016 and December&nbsp;31, 2016. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT
STYLE="font-family:Times New Roman" SIZE="2"><B>Allowance for Doubtful Accounts &#150;</B> The Company recognizes a provision for doubtful accounts each month based upon the Company&#146;s experience in collecting electric and gas utility service
accounts receivable in prior years. At the end of each month, an analysis of the delinquent receivables is performed which takes into account an assumption about the cash recovery of delinquent receivables. The analysis also calculates the amount of
written-off receivables that are recoverable through regulatory rate reconciling mechanisms. The Company&#146;s distribution utilities </FONT></P>

are authorized by regulators to recover the costs of their energy commodity portion of bad debts through rate mechanisms. Also, the electric and gas divisions of Fitchburg are authorized to
recover through rates past due amounts associated with hardship accounts that are protected from shut-off.&nbsp;Evaluating the adequacy of the Allowance for Doubtful Accounts requires judgment about the assumptions used in the analysis, including
the level of customers enrolling in payment plans with the Company. It has been the Company&#146;s experience that the assumptions it has used in evaluating the adequacy of the Allowance for Doubtful Accounts have proven to be reasonably accurate.

Included in Regulatory Assets as of September&nbsp;30, 2017 are $1.4 million of deferred storm charges to be recovered over the next year and $7.4 million of environmental costs, rate case costs and other expenditures to be recovered over varying
periods in the next seven years. Regulators have authorized recovery of these expenditures, but without a return. Regulatory commissions can reach different conclusions about the recovery of costs, which can have a material impact on the
Company&#146;s Consolidated Financial Statements. The Company believes it is probable that its regulated distribution and transmission utilities will recover their investments in long-lived assets, including regulatory assets. If the Company, or a
portion of its assets or operations, were to cease meeting the criteria for application of these accounting rules, accounting standards for businesses in general would become applicable and immediate recognition of any previously deferred costs, or
a portion of deferred costs, would be required in the year in which the criteria are no longer met, if such deferred costs were not recoverable in the portion of the business that continues to meet the criteria for application of the FASB
Codification topic on Regulated Operations. If unable to continue to apply the FASB Codification provisions for Regulated Operations, the Company would be required to apply the provisions for the Discontinuation of Rate-Regulated Accounting included
in the FASB Codification. In the Company&#146;s opinion, its regulated operations will be subject to the FASB Codification provisions for Regulated Operations for the foreseeable future. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT

any additional relevant components of the contract, the Company determines and documents whether the contract qualifies as a derivative instrument as defined in the FASB Codification. The Company has determined that none of its energy supply
contracts, other than the regulatory approved hedging program, described below, qualifies as a derivative instrument under the guidance set forth in the FASB Codification. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT

Utilities releases certain natural gas pipeline and storage assets, resells the natural gas storage inventory to an asset manager and subsequently repurchases the inventory over the course of the natural gas heating season at the same price at which
it sold the natural gas inventory to the asset manager. The gas inventory related to these agreements is recorded in Exchange Gas Receivable on the Company&#146;s Consolidated Balance Sheets while the corresponding obligations are recorded in Energy
Supply Obligations. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">Renewable Energy Portfolio Standards &#150; Renewable Energy Portfolio Standards (RPS) require retail electricity
suppliers, including public utilities, to demonstrate that required percentages of their sales are met with power generated from certain types of resources or technologies. Compliance is demonstrated by purchasing and retiring Renewable Energy
Certificates (REC) generated by facilities approved by the state as qualifying for REC treatment. Unitil Energy and Fitchburg purchase RECs in compliance with RPS legislation in New Hampshire and Massachusetts for supply provided to default service
customers. RPS compliance costs are a supply cost that is recovered in customer default service rates. Unitil Energy and Fitchburg collect RPS compliance costs from customers throughout the year and demonstrate compliance for each calendar year on
the following July&nbsp;1. Due to timing differences between collection of revenue from customers and payment of REC costs to suppliers, Unitil Energy and Fitchburg typically maintain accrued revenue for RPS compliance which is recorded in Accrued
Revenue with a corresponding liability in Energy Supply Obligations on the Company&#146;s Consolidated Balance Sheets. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">Fitchburg has entered
into long-term renewable contracts for electric energy and/or renewable energy credits pursuant to Massachusetts legislation, specifically, the Act Relative to Green Communities of 2008 and the Act Relative to Competitively Priced Electricity
(2012)&nbsp;in the Commonwealth, and the MDPU&#146;s regulations implementing the legislation. The generating facilities associated with three of these contracts have been constructed and are operating. A recent round of long-term renewable energy
procurements was conducted during 2016 and several contracts were finalized and submitted to the MDPU in September, 2017 for approval. Additional procurements have been issued in compliance with the Act to Promote Energy Diversity (2016). Fitchburg
recovers the costs associated with long-term renewable contracts on a fully reconciling basis through a MDPU-approved cost recovery mechanism. </FONT></P>
<P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">Power Supply Contract Divestitures &#150; As a result of the restructuring of the utility industry in New Hampshire and Massachusetts, Unitil
Energy&#146;s and Fitchburg&#146;s customers have the opportunity to purchase their electric or natural gas supplies from third-party suppliers. In connection with the implementation of retail choice, Unitil Power, which formerly functioned as the
wholesale power supply provider for Unitil Energy, and Fitchburg divested their long-term power supply contracts through the sale of the entitlements to the electricity sold under those contracts. Unitil Energy and Fitchburg recover in their rates
all the costs associated with the divestiture of their power supply portfolios and have secured regulatory approval from the NHPUC and MDPU, respectively, for the recovery of power supply-related stranded costs. The obligations related to these
divestitures are recorded in Energy Supply Obligations on the Company&#146;s Consolidated Balance Sheets with corresponding regulatory assets recorded in Accrued Revenue (current portion) and Regulatory Assets (long-term portion). </FONT></P>

the FASB issued Accounting Standards Update ASU No.&nbsp;2017-09, &#147;Compensation &#150; Stock Compensation (Topic 718) &#150; Scope of Modification Accounting&#148;, to clarify when to account for a change to the terms or conditions of a
share-based payment award as a modification. Under the new standard, modification is required only if the fair value, the vesting conditions, or the classification of an award as equity or liability changes as a result of the change in terms or
conditions. The amendments are effective for all entities for annual periods beginning after December&nbsp;15, 2017, including interim periods within those annual periods, and will be applied prospectively. Early adoption is permitted. The Company

FASB issued ASU No.&nbsp;2017-07, &#147;Compensation &#150; Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.&#148; The ASU amends the existing guidance relating to
the presentation of net periodic pension cost and net periodic postretirement benefit cost. The amendment requires an employer to disaggregate the service cost component from the other components of net benefit cost and provides explicit guidance on
how to present the service cost component and other components in the income statement. In addition, on a prospective basis, the ASU limits the component of net benefit cost eligible to be capitalized to service costs. The ASU will be effective for
the Company on January&nbsp;1, 2018, with early adoption permitted. Although the Company is currently evaluating the impact the guidance will have on the Consolidated Financial Statements and related disclosures, it is not expected to have a
material impact to financial results. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">In May 2014, the FASB issued ASU No.&nbsp;2014-09, Revenue from Contracts with Customers, Topic 606,
which amends existing revenue recognition guidance, effective January&nbsp;1, 2018. The objective of the new standard is to provide a single, comprehensive revenue recognition model for all contracts with customers to improve comparability across

the new guidance will not result in a significant shift in the timing of revenue recognition for such sales. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">The Company intends to use the
modified retrospective method when adopting the new standard on January&nbsp;1, 2018. The Company expects that the impact of the new guidance will be immaterial to the Consolidated Financial Statements. Upon adoption of ASU 2014-09, the Company
plans to disclose revenues from contracts with customers separately from rate adjustment mechanism revenue. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">In March 2016, the FASB issued
ASU 2016-09, which provides for improvements to employee share-based payment accounting. ASU 2016-09 is effective for fiscal years, and interim periods within those years, beginning after December&nbsp;15, 2016. ASU 2016-09 simplifies several
aspects of the accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. The Company
adopted this new guidance in the first quarter of 2017 and it did not have an impact on the Company&#146;s Consolidated Financial Statements. </FONT></P>

recognition of right-of-use assets and lease liabilities for most leases.&nbsp;This guidance will be effective for interim and annual reporting periods beginning after Dec. 15, 2018.&nbsp;The Company has not yet fully determined the impacts of
implementation.&nbsp;However, adoption is expected to occur on Jan. 1, 2019 utilizing the practical expedients provided by the standard.&nbsp;As such, agreements entered into prior to Jan. 1, 2017 that are currently considered leases are expected to
be recognized on the consolidated balance sheet, including contracts for use of office space and equipment. The Company expects that similar agreements entered into after December&nbsp;31, 2016 will generally qualify as leases under the new
standard, but has not yet completed its evaluation of certain other contracts, including arrangements for the secondary use of assets, such as land easements. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT
STYLE="font-family:Times New Roman" SIZE="2">In January 2016, the FASB issued Accounting Standards Update (ASU) 2016-01 which addresses certain aspects of recognition, measurement, presentation and disclosure of financial instruments. A financial
instrument is defined as cash, evidence of ownership interest in a company or other entity, or a contract that both: (i)&nbsp;imposes on one entity a contractual obligation either to deliver cash or another financial instrument to a second entity or
to exchange other financial instruments on potentially unfavorable terms with the second entity and (ii)&nbsp;conveys to that second entity a contractual right either to receive cash or another financial instruments from the first entity or to
exchange other financial instruments on potentially favorable terms with the first entity. This pronouncement is effective for financial statements issued for annual periods beginning after December&nbsp;15, 2017 and interim periods within those
annual periods with earlier application permitted as of the beginning of the fiscal year of adoption. The Company is evaluating the impact that this new guidance will have on the Company&#146;s Consolidated Financial Statements. </FONT></P>

the Company&#146;s debt securities, which have all been sold through private placements. If there were an active market for the Company&#146;s debt securities, the fair value of the Company&#146;s long-term debt would be estimated based on the
quoted market prices for the same or similar issues, or on the current rates offered to the Company for debt of the same remaining maturities. The fair value of the Company&#146;s long-term debt is estimated using Level 2 inputs (valuations based on
quoted prices available in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, inputs other than quoted prices that are directly observable, and inputs derived
principally from market data.) In estimating the fair value of the Company&#146;s long-term debt, the assumed market yield reflects the Moody&#146;s Baa Utility Bond Average Yield. Costs, including prepayment costs, associated with the early
settlement of long-term debt are not taken into consideration in determining fair value. </FONT></P> <P STYLE="font-size:12px;margin-top:0px;margin-bottom:0px">&nbsp;</P>

Modernization order, setting forth a requirement that each electric distribution company submit a ten-year strategic Grid Modernization Plan (GMP). As part of the GMP, each company must include a five-year Short-Term Investment Plan (STIP), which
must include an approach to achieving advanced metering functionality within five years of the Department&#146;s approval of the GMP. The filing of a GMP is a recurring obligation and must be updated as part of subsequent base distribution rate
cases, which by statute must occur no less often than every five years. Capital investments contained in the STIP are eligible for pre-authorization, meaning that the MDPU will not revisit in later filings whether the Company should have proceeded
with these investments. Fitchburg and the Commonwealth&#146;s three other electric distribution companies filed their initial GMPs on August&nbsp;19, 2015. These filings are currently under MDPU review and remain pending. </FONT></P>

Owners&#146; Regional Network Service and Local Network Service formula rates. On April&nbsp;14, 2017, the U.S. Court of Appeals for the D.C. Circuit issued an opinion vacating a decision of the FERC with respect to these formula rates, and remanded
it for further proceedings. The FERC had found that the Transmission Owners existing ROE was unlawful, and had set a new ROE. The Court found that the FERC had failed to articulate a satisfactory explanation for its orders. At this time, the ROE set
in the vacated order will remain in place until further FERC action is taken. Fitchburg and Unitil Energy are Participating Transmission Owners, although Unitil Energy does not own transmission plant. To the extent that these proceedings result in
any changes to the rates being charged, a retroactive reconciliation may be required. The Company does not believe that these proceedings will have a material adverse impact on the Company&#146;s financial condition or results of operations.

allegedly incurred by customers in connection with the loss of electric service during the ice storm in Fitchburg&#146;s service territory in December 2008. The Massachusetts Supreme Judicial Court issued an order denying class certification status

Unitil Corporation (NYSE: UTL) (<U>www.unitil.com</U>) today announced Net Income of $2.3 million, or $0.16 per share, for the third quarter of 2017, a decrease of $1.2 million, or $0.09 per share, compared to the third quarter of 2016. For the nine
months ended September&nbsp;30, 2017, the Company reported Net Income of $17.8 million, or $1.27 per share, an increase of $0.9 million, or $0.06 per share, compared to the same nine month period in 2016. The decrease in earnings for the third
quarter of 2017 was driven by lower electric sales margins, reflecting milder summer weather in 2017 compared to the same period in 2016 and higher operating expenses, partially offset by higher gas sales margins and customer growth. The increase in
earnings for the first nine months of 2017 was driven by higher natural gas and electric sales margins and customer growth. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">&#147;Our third
quarter results reflect milder summer weather compared to last year, which adversely affected sales of electricity for cooling purposes,&#148; said Robert G. Schoenberger, Unitil&#146;s Chairman and Chief Executive Officer. &#147;However, we are
pleased with the continued underlying customer growth in our natural gas and electric businesses and the positive results of our regulatory initiatives, which are reflected in the higher earnings for the year-to-date period.&#148; </FONT></P>
<P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">Natural gas sales margins were $16.8 million and $75.3 million in the three and nine months ended September&nbsp;30, 2017, respectively, resulting in
increases of $0.8 million and $3.6 million, respectively, compared to the same periods in 2016. Gas sales margin in the third quarter was positively affected by higher natural gas distribution rates of $0.6 million and higher sales volume and
customer growth of $0.2 million. For the nine month period, gas sales margin was positively affected by higher natural gas distribution rates of $2.3 million and higher sales volume and customer growth of $1.3 million. </FONT></P>
<P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">Natural gas therm sales increased 6.2% and 4.9% in the three and nine month periods ended September&nbsp;30, 2017, respectively, compared to the same
periods in 2016. The increase in gas therm sales in the Company&#146;s service areas was driven by customer growth and, for the nine month period, slightly colder winter weather in 2017 compared to 2016. As of September&nbsp;30, 2017, the number of
total natural gas customers served has increased by 1,200 in the last twelve months. </FONT></P>

sales margins were $24.8 million and $70.1 million in the three and nine months ended September&nbsp;30, 2017, respectively, resulting in a decrease of $0.8&nbsp;million and an increase of $4.0&nbsp;million, respectively, compared to the same
periods in 2016. Electric sales margin in the third quarter was negatively affected by lower sales volume due to milder weather of $0.8 million, offset by higher distribution rates of $0.8 million and customer growth of $0.1 million. Also, the
Company recognized an adjustment of $0.9 million to true up the collection of transmission revenues in the third quarter of 2016. For the nine month period, electric sales margin was positively affected by higher electric distribution rates of $4.4
million and customer growth of $0.4 million, partially offset by lower sales volumes due to the impact of milder summer weather of $0.8 million. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT

expenses increased $2.3 million and $4.4 million for the three and nine months ended September&nbsp;30, 2017, respectively, compared to the same periods in 2016. The increase in the three month period reflects higher compensation and benefit costs
of $0.7 million and higher utility operating costs of $1.6 million: including $0.7 million of higher vegetation management costs, which are recovered in reconciling rate adjustment mechanisms and reflected in electric sales margin, higher system
maintenance costs of $0.6 million, and higher all other utility operating costs of $0.3 million. The increase in O&amp;M expenses of $4.4 million in the nine month period reflects higher compensation and benefit costs of $1.1 million and higher

an increase in interest expense on short-term debt, partially offset by higher net interest income on regulatory assets/liabilities and repayment of higher cost long-term debt. The Company has announced that it expects to close on $90 million of

 earnings are seasonal and are typically higher in the first and
 fourth quarters when customers use natural gas for heating
 purposes.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Unitil&amp;#x2019;s principal
 business is the local distribution of electricity in the
 southeastern seacoast and state capital regions of New Hampshire
 and the greater Fitchburg area of north central Massachusetts, and
 the local distribution of natural gas in southeastern New
 Hampshire, portions of southern and central Maine and in the
 greater Fitchburg area of north central Massachusetts. Unitil has
 three distribution utility subsidiaries, Unitil Energy, which
 operates in New Hampshire, Fitchburg, which operates in
 Massachusetts and Northern Utilities, which operates in New
 Hampshire and Maine (collectively referred to as the distribution
 utilities).&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Granite State is a natural
 gas transportation pipeline, operating 86 miles of underground gas
 transmission pipeline primarily located in Maine and New Hampshire.
 Granite State provides Northern Utilities with interconnection to
 three major natural gas pipelines and access to domestic natural
 gas supplies in the south and Canadian natural gas supplies in the
 north. Granite State derives its revenues principally from the
 transportation services provided to Northern Utilities and, to a
 lesser extent, third-party marketers.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;A fifth utility subsidiary,
 Unitil Power, formerly functioned as the full requirements
 wholesale power supply provider for Unitil Energy. In connection
 with the implementation of electric industry restructuring in New
 Hampshire, Unitil Power ceased being the wholesale supplier of
 Unitil Energy on May&amp;#xA0;1, 2003 and divested of its long-term
 power supply contracts through the sale of the entitlements to the
 electricity associated with various electric power supply contracts
 it had acquired to serve Unitil Energy&amp;#x2019;s
 customers.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Unitil also has three other
 wholly-owned subsidiaries: Unitil Service; Unitil Realty; and
 Unitil Resources. Unitil Service provides, at cost, a variety of
 administrative and professional services, including regulatory,
 financial, accounting, human resources, engineering, operations,
 technology, energy management and management services on a
 centralized basis to its affiliated Unitil companies. Unitil Realty
 owns and manages the Company&amp;#x2019;s corporate office in Hampton,
 New Hampshire and leases this facility to Unitil Service under a
 long-term lease arrangement. Unitil Resources is the
 Company&amp;#x2019;s wholly-owned non-regulated subsidiary. Usource,
 Inc. and Usource L.L.C. (collectively, Usource) are wholly-owned
 subsidiaries of Unitil Resources. Usource provides brokering and
 advisory services to large commercial and industrial customers in
 the northeastern United States.&lt;/font&gt;&lt;/p&gt;

 &amp;#x2013;&lt;/b&gt; The accompanying unaudited Consolidated Financial
 Statements of Unitil have been prepared in accordance with the
 instructions to Form 10-Q and include all of the information and
 footnotes required by generally accepted accounting principles. In
 the opinion of management, all adjustments considered necessary for
 a fair presentation have been included and are of a normal and
 recurring nature. The results of operations for the three and nine
 months ended September&amp;#xA0;30, 2017 are not necessarily indicative
 of results to be expected for the year ending December&amp;#xA0;31,
 2017. For further information, please refer to Note 1 of Part II to
 the Consolidated Financial Statements &amp;#x2013; &amp;#x201C;Summary of
 Significant Accounting Policies&amp;#x201D; of the Company&amp;#x2019;s Form
 10-K for the year ended December&amp;#xA0;31, 2016, as filed with the
 Securities and Exchange Commission (SEC) on February&amp;#xA0;2, 2017,
 for a description of the Company&amp;#x2019;s Basis of
 Presentation.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;&lt;b&gt;Income Taxes &amp;#x2013;&lt;/b&gt;
 The Company is subject to Federal and State income taxes as well as
 various other business taxes. This process involves estimating the
 Company&amp;#x2019;s current tax liabilities as well as assessing
 temporary and permanent differences resulting from the timing of
 the deductions of expenses and recognition of taxable income for
 tax and book accounting purposes. These temporary differences
 result in deferred tax assets and liabilities, which are included
 in the Company&amp;#x2019;s Consolidated Balance Sheets. The Company
 accounts for income tax assets, liabilities and expenses in
 accordance with the Financial Accounting Standards Board (FASB)
 Codification guidance on Income Taxes. The Company classifies
 penalty and interest expense related to income tax liabilities as
 income tax expense and interest expense, respectively, in the
 Consolidated Statements of Earnings.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Provisions for income taxes
 are calculated in each of the jurisdictions in which the Company
 operates for each period for which a statement of earnings is
 presented. The Company accounts for income taxes in accordance with
 the FASB Codification guidance on Income Taxes, which requires an
 asset and liability approach for the financial accounting and
 reporting of income taxes. Significant judgments and estimates are
 required in determining the current and deferred tax assets and
 liabilities. The Company&amp;#x2019;s current and deferred tax assets
 and liabilities reflect its best assessment of estimated future
 taxes to be paid. In accordance with the FASB Codification, the
 Company periodically assesses the realization of its deferred tax
 assets and liabilities and adjusts the income tax provision, the
 current tax liability and deferred taxes in the period in which the
 facts and circumstances which gave rise to the revision become
 known.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;&lt;b&gt;Cash and Cash
 Equivalents &amp;#x2013;&lt;/b&gt; Cash and Cash Equivalents include all cash
 and cash equivalents to which the Company has legal title. Cash
 equivalents include short-term investments with original maturities
 of three months or less and interest bearing deposits. The
 Company&amp;#x2019;s cash and cash equivalents are held at financial
 institutions and at times may exceed federally insured limits. The
 Company has not experienced any losses in such accounts. Under the
 Independent System Operator&amp;#x2014;New England (ISO-NE) Financial
 Assurance Policy (Policy), Unitil&amp;#x2019;s subsidiaries Unitil
 Energy, Fitchburg and Unitil Power are required to provide
 assurance of their ability to satisfy their obligations to ISO-NE.
 Under this Policy, Unitil&amp;#x2019;s subsidiaries provide cash
 deposits covering approximately 2-1/2 months of outstanding
 obligations, less credit amounts that are based on the
 Company&amp;#x2019;s credit rating. As of September&amp;#xA0;30,
 2017,&amp;#xA0;September&amp;#xA0;30, 2016 and December&amp;#xA0;31, 2016, the
 Unitil subsidiaries had deposited $4.8 million, $3.5 million and
 $2.8 million, respectively to satisfy their ISO-NE obligations. In
 addition, Northern Utilities has cash margin deposits to satisfy
 requirements for its natural gas hedging program. There were no
 cash margin deposits at Northern Utilities as of September&amp;#xA0;30,
 2017,&amp;#xA0;September&amp;#xA0;30, 2016 and December&amp;#xA0;31,
 2016.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;&lt;b&gt;Allowance for Doubtful
 Accounts &amp;#x2013;&lt;/b&gt; The Company recognizes a provision for
 doubtful accounts each month based upon the Company&amp;#x2019;s
 experience in collecting electric and gas utility service accounts
 receivable in prior years. At the end of each month, an analysis of
 the delinquent receivables is performed which takes into account an
 assumption about the cash recovery of delinquent receivables. The
 analysis also calculates the amount of written-off receivables that
 are recoverable through regulatory rate reconciling mechanisms. The
 Company&amp;#x2019;s distribution utilities are authorized by regulators
 to recover the costs of their energy commodity portion of bad debts
 through rate mechanisms. Also, the electric and gas divisions of
 Fitchburg are authorized to recover through rates past due amounts
 associated with hardship accounts that are protected from
 shut-off.&amp;#xA0;Evaluating the adequacy of the Allowance for
 Doubtful Accounts requires judgment about the assumptions used in
 the analysis, including the level of customers enrolling in payment
 plans with the Company. It has been the Company&amp;#x2019;s experience
 that the assumptions it has used in evaluating the adequacy of the
 Allowance for Doubtful Accounts have proven to be reasonably
 accurate.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Allowance for Doubtful
 Accounts as of September&amp;#xA0;30, 2017,&amp;#xA0;September&amp;#xA0;30,
 2016 and December&amp;#xA0;31, 2016, which is included in Accounts
 Receivable, net on the accompanying unaudited consolidated balance
 sheets, was as follows:&lt;/font&gt;&lt;/p&gt;

 &amp;#x2013;&lt;/b&gt; The cost of additions to Utility Plant and the cost of
 renewals and betterments are capitalized. Cost consists of labor,
 materials, services and certain indirect construction costs,
 including an allowance for funds used during construction (AFUDC).
 The costs of current repairs and minor replacements are charged to
 appropriate operating expense accounts. The original cost of
 utility plant retired or otherwise disposed of is charged to the
 accumulated provision for depreciation. The Company includes in its
 mass asset depreciation rates, which are periodically reviewed as
 part of its ratemaking proceedings, cost of removal amounts to
 provide for future negative salvage value. At September&amp;#xA0;30,
 2017,&amp;#xA0;September&amp;#xA0;30, 2016 and December&amp;#xA0;31, 2016, the
 Company estimates that the cost of removal amounts, which are
 recorded on the Consolidated Balance Sheets in Cost of Removal
 Obligations are $84.8 million, $77.4 million, and $77.0 million,
 respectively.&lt;/font&gt;&lt;/p&gt;

 &amp;#x2013;&lt;/b&gt; The Company&amp;#x2019;s principal business is the
 distribution of electricity and natural gas by the three
 distribution utilities: Unitil Energy, Fitchburg and Northern
 Utilities. Unitil Energy and Fitchburg are subject to regulation by
 the FERC. Fitchburg is also regulated by the Massachusetts
 Department of Public Utilities (MDPU), Unitil Energy is regulated
 by the New Hampshire Public Utilities Commission (NHPUC) and
 Northern Utilities is regulated by the Maine Public Utilities
 Commission (MPUC) and NHPUC. Granite State, the Company&amp;#x2019;s
 natural gas transmission pipeline, is regulated by the FERC.
 Accordingly, the Company uses the Regulated Operations guidance as
 set forth in the FASB Codification. The Company has recorded
 Regulatory Assets and Regulatory Liabilities which will be
 recovered from customers, or applied for customer benefit, in
 accordance with rate provisions approved by the applicable public
 utility regulatory commission.&lt;/font&gt;&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Generally, the Company
 receives a return on investment on its regulated assets for which a
 cash outflow has been made. Included in Regulatory Assets as of
 September&amp;#xA0;30, 2017 are $1.4 million of deferred storm charges
 to be recovered over the next year and $7.4 million of
 environmental costs, rate case costs and other expenditures to be
 recovered over varying periods in the next seven years. Regulators
 have authorized recovery of these expenditures, but without a
 return. Regulatory commissions can reach different conclusions
 about the recovery of costs, which can have a material impact on
 the Company&amp;#x2019;s Consolidated Financial Statements. The Company
 believes it is probable that its regulated distribution and
 transmission utilities will recover their investments in long-lived
 assets, including regulatory assets. If the Company, or a portion
 of its assets or operations, were to cease meeting the criteria for
 application of these accounting rules, accounting standards for
 businesses in general would become applicable and immediate
 recognition of any previously deferred costs, or a portion of
 deferred costs, would be required in the year in which the criteria
 are no longer met, if such deferred costs were not recoverable in
 the portion of the business that continues to meet the criteria for
 application of the FASB Codification topic on Regulated Operations.
 If unable to continue to apply the FASB Codification provisions for
 Regulated Operations, the Company would be required to apply the
 provisions for the Discontinuation of Rate-Regulated Accounting
 included in the FASB Codification. In the Company&amp;#x2019;s opinion,
 its regulated operations will be subject to the FASB Codification
 provisions for Regulated Operations for the foreseeable
 future.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;&lt;b&gt;Derivatives &amp;#x2013;&lt;/b&gt;
 The Company&amp;#x2019;s regulated energy subsidiaries enter into energy
 supply contracts to serve their electric and gas customers. The
 Company follows a procedure for determining whether each contract
 qualifies as a derivative instrument under the guidance provided by
 the FASB Codification on Derivatives and Hedging. For each
 contract, the Company reviews and documents the key terms of the
 contract. Based on those terms and any additional relevant
 components of the contract, the Company determines and documents
 whether the contract qualifies as a derivative instrument as
 defined in the FASB Codification. The Company has determined that
 none of its energy supply contracts, other than the regulatory
 approved hedging program, described below, qualifies as a
 derivative instrument under the guidance set forth in the FASB
 Codification.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Company has a
 regulatory approved hedging program for Northern Utilities designed
 to fix or cap a portion of its gas supply costs for the coming
 years of service. Under the program, the Company may purchase call
 option contracts on NYMEX natural gas futures contracts for future
 winter period months.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Any gains or losses
 resulting from the change in the fair value of these derivatives
 are passed through to ratepayers directly through Northern
 Utilities&amp;#x2019; Cost of Gas Clause. The fair value of these
 derivatives is determined using Level 2 inputs (valuations based on
 quoted prices in markets that are not active or for which all
 significant inputs are observable, either directly or indirectly),
 specifically based on the NYMEX closing prices for outstanding
 contracts as of the balance sheet date. As a result of the
 ratemaking process, the Company records gains and losses resulting
 from the change in fair value of the derivatives as regulatory
 liabilities or assets, then reclassifies these gains or losses into
 Cost of Gas Sales when the gains and losses are passed through to
 customers through the Cost of Gas Clause.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;As of September&amp;#xA0;30,
 2017,&amp;#xA0;September&amp;#xA0;30, 2016 and December&amp;#xA0;31, 2016 the
 Company had 1.2 billion, 2.9 billion and 2.0 billion cubic feet
 (BCF), respectively, outstanding in natural gas futures and options
 contracts under its hedging program.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;As of September&amp;#xA0;30,
 2017,&amp;#xA0;September&amp;#xA0;30, 2016 and December&amp;#xA0;31, 2016, the
 Company&amp;#x2019;s derivatives that are not designated as hedging
 instruments under FASB ASC 815-20 have a fair value of $0.1
 million, $0.2 million and $0.4 million, respectively.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;&lt;b&gt;Investments in
 Marketable Securities&lt;/b&gt; &amp;#x2013; In 2015, the Company established
 a trust through which it invests in a variety of equity and fixed
 income mutual funds. These funds are intended to satisfy
 obligations under the Company&amp;#x2019;s Supplemental Executive
 Retirement Plan (&amp;#x201C;SERP&amp;#x201D;) (See further discussion of the
 SERP in Note 9.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;At September&amp;#xA0;30,
 2017,&amp;#xA0;September&amp;#xA0;30, 2016 and December&amp;#xA0;31, 2016, the
 fair value of the Company&amp;#x2019;s investments in these trading
 securities, which are recorded on the Consolidated Balance Sheets
 in Other Assets, were $3.4 million, $1.9 million and $1.9 million,
 respectively, as shown in the table below. These investments are
 valued based on quoted prices from active markets and are
 categorized in Level 1 as they are actively traded and no valuation
 adjustments have been applied. Changes in the fair value of these
 investments are recorded in Other Expense, net.&lt;/font&gt;&lt;/p&gt;

 &amp;#x2013; Northern Utilities enters into gas exchange agreements
 under which Northern Utilities releases certain natural gas
 pipeline and storage assets, resells the natural gas storage
 inventory to an asset manager and subsequently repurchases the
 inventory over the course of the natural gas heating season at the
 same price at which it sold the natural gas inventory to the asset
 manager. The gas inventory related to these agreements is recorded
 in Exchange Gas Receivable on the Company&amp;#x2019;s Consolidated

 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Renewable Energy Portfolio
 Standards &amp;#x2013; Renewable Energy Portfolio Standards (RPS)
 require retail electricity suppliers, including public utilities,
 to demonstrate that required percentages of their sales are met
 with power generated from certain types of resources or
 technologies. Compliance is demonstrated by purchasing and retiring
 Renewable Energy Certificates (REC) generated by facilities
 approved by the state as qualifying for REC treatment. Unitil
 Energy and Fitchburg purchase RECs in compliance with RPS
 legislation in New Hampshire and Massachusetts for supply provided
 to default service customers. RPS compliance costs are a supply
 cost that is recovered in customer default service rates. Unitil
 Energy and Fitchburg collect RPS compliance costs from customers
 throughout the year and demonstrate compliance for each calendar
 year on the following July&amp;#xA0;1. Due to timing differences
 between collection of revenue from customers and payment of REC
 costs to suppliers, Unitil Energy and Fitchburg typically maintain
 accrued revenue for RPS compliance which is recorded in Accrued
 Revenue with a corresponding liability in Energy Supply Obligations
 on the Company&amp;#x2019;s Consolidated Balance Sheets.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Fitchburg has entered into
 long-term renewable contracts for electric energy and/or renewable
 energy credits pursuant to Massachusetts legislation, specifically,
 the Act Relative to Green Communities of 2008 and the Act Relative
 to Competitively Priced Electricity (2012)&amp;#xA0;in the
 Commonwealth, and the MDPU&amp;#x2019;s regulations implementing the
 legislation. The generating facilities associated with three of
 these contracts have been constructed and are operating. A recent
 round of long-term renewable energy procurements was conducted
 during 2016 and several contracts were finalized and submitted to
 the MDPU in September, 2017 for approval. Additional procurements
 have been issued in compliance with the Act to Promote Energy
 Diversity (2016). Fitchburg recovers the costs associated with
 long-term renewable contracts on a fully reconciling basis through
 a MDPU-approved cost recovery mechanism.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Power Supply Contract
 Divestitures &amp;#x2013; As a result of the restructuring of the
 utility industry in New Hampshire and Massachusetts, Unitil
 Energy&amp;#x2019;s and Fitchburg&amp;#x2019;s customers have the opportunity
 to purchase their electric or natural gas supplies from third-party
 suppliers. In connection with the implementation of retail choice,
 Unitil Power, which formerly functioned as the wholesale power
 supply provider for Unitil Energy, and Fitchburg divested their
 long-term power supply contracts through the sale of the
 entitlements to the electricity sold under those contracts. Unitil
 Energy and Fitchburg recover in their rates all the costs
 associated with the divestiture of their power supply portfolios
 and have secured regulatory approval from the NHPUC and MDPU,
 respectively, for the recovery of power supply-related stranded
 costs. The obligations related to these divestitures are recorded
 in Energy Supply Obligations on the Company&amp;#x2019;s Consolidated
 Balance Sheets with corresponding regulatory assets recorded in
 Accrued Revenue (current portion) and Regulatory Assets (long-term
 portion).&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;&lt;b&gt;Recently Issued
 Pronouncements &amp;#x2013;&lt;/b&gt; In August 2017, the FASB issued
 Accounting Standards Update (ASU) No.&amp;#xA0;2017-12,
 &amp;#x201C;Derivatives and Hedging (Topic 815), to improve the
 financial reporting of hedging relationships to better portray the
 economic results of an entity&amp;#x2019;s risk management activities in
 its financial statements and to make certain targeted improvements
 to simplify the application of the hedge accounting guidance in
 current generally accepted accounting principles in the United
 States of America (GAAP). The amendments are effective for all
 entities for annual periods beginning after December&amp;#xA0;15, 2018,
 including interim periods within those annual periods, and will be
 applied prospectively. Early adoption is permitted. The Company
 adopted this new guidance and it did not have a material impact on
 the Company&amp;#x2019;s Consolidated Financial Statements.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;In May 2017, the FASB
 issued Accounting Standards Update ASU No.&amp;#xA0;2017-09,
 &amp;#x201C;Compensation &amp;#x2013; Stock Compensation (Topic 718) &amp;#x2013;
 Scope of Modification Accounting&amp;#x201D;, to clarify when to account
 for a change to the terms or conditions of a share-based payment
 award as a modification. Under the new standard, modification is
 required only if the fair value, the vesting conditions, or the
 classification of an award as equity or liability changes as a
 result of the change in terms or conditions. The amendments are
 effective for all entities for annual periods beginning after
 December&amp;#xA0;15, 2017, including interim periods within those
 annual periods, and will be applied prospectively. Early adoption
 is permitted. The Company adopted this new guidance and it did not
 have a material impact on the Company&amp;#x2019;s Consolidated
 Financial Statements.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;In March 2017, the FASB
 issued ASU No.&amp;#xA0;2017-07, &amp;#x201C;Compensation &amp;#x2013; Retirement
 Benefits (Topic 715): Improving the Presentation of Net Periodic
 Pension Cost and Net Periodic Postretirement Benefit Cost.&amp;#x201D;
 The ASU amends the existing guidance relating to the presentation
 of net periodic pension cost and net periodic postretirement
 benefit cost. The amendment requires an employer to disaggregate
 the service cost component from the other components of net benefit
 cost and provides explicit guidance on how to present the service
 cost component and other components in the income statement. In
 addition, on a prospective basis, the ASU limits the component of
 net benefit cost eligible to be capitalized to service costs. The
 ASU will be effective for the Company on January&amp;#xA0;1, 2018, with
 early adoption permitted. Although the Company is currently
 evaluating the impact the guidance will have on the Consolidated
 Financial Statements and related disclosures, it is not expected to
 have a material impact to financial results.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;In May 2014, the FASB
 issued ASU No.&amp;#xA0;2014-09, Revenue from Contracts with Customers,
 Topic 606, which amends existing revenue recognition guidance,
 effective January&amp;#xA0;1, 2018. The objective of the new standard
 is to provide a single, comprehensive revenue recognition model for
 all contracts with customers to improve comparability across
 entities, industries, jurisdictions, and capital markets and to
 provide more useful information to users of financial statements
 through improved and expanded disclosure requirements.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The majority of the
 Company&amp;#x2019;s revenue, including energy provided to customers, is
 from tariff offerings that provide natural gas or electricity
 without a defined contractual term. For such arrangements, the
 Company generally expects that the revenue from contracts with
 these customers will continue to be equivalent to the electricity
 or natural gas supplied and billed in that period (including
 unbilled revenues) and the adoption of the new guidance will not
 result in a significant shift in the timing of revenue recognition
 for such sales.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Company intends to use
 the modified retrospective method when adopting the new standard on
 January&amp;#xA0;1, 2018. The Company expects that the impact of the
 new guidance will be immaterial to the Consolidated Financial
 Statements. Upon adoption of ASU 2014-09, the Company plans to
 disclose revenues from contracts with customers separately from
 rate adjustment mechanism revenue.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;In March 2016, the FASB
 issued ASU 2016-09, which provides for improvements to employee
 share-based payment accounting. ASU 2016-09 is effective for fiscal
 years, and interim periods within those years, beginning after
 December&amp;#xA0;15, 2016. ASU 2016-09 simplifies several aspects of
 the accounting for employee share-based payment transactions,
 including the accounting for income taxes, forfeitures, and
 statutory tax withholding requirements, as well as classification
 in the statement of cash flows. The Company adopted this new
 guidance in the first quarter of 2017 and it did not have an impact
 on the Company&amp;#x2019;s Consolidated Financial
 Statements.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 12px"&gt;
 &amp;#xA0;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 0px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;In February 2016, the FASB
 issued ASU 2016-02, Leases, Topic 842, which for lessees requires
 balance sheet recognition of right-of-use assets and lease
 liabilities for most leases.&amp;#xA0;This guidance will be effective
 for interim and annual reporting periods beginning after Dec. 15,
 2018.&amp;#xA0;The Company has not yet fully determined the impacts of
 implementation.&amp;#xA0;However, adoption is expected to occur on Jan.
 1, 2019 utilizing the practical expedients provided by the
 standard.&amp;#xA0;As such, agreements entered into prior to Jan. 1,
 2017 that are currently considered leases are expected to be
 recognized on the consolidated balance sheet, including contracts
 for use of office space and equipment. The Company expects that
 similar agreements entered into after December&amp;#xA0;31, 2016 will
 generally qualify as leases under the new standard, but has not yet
 completed its evaluation of certain other contracts, including
 arrangements for the secondary use of assets, such as land
 easements.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;In January 2016, the FASB
 issued Accounting Standards Update (ASU) 2016-01 which addresses
 certain aspects of recognition, measurement, presentation and
 disclosure of financial instruments. A financial instrument is
 defined as cash, evidence of ownership interest in a company or
 other entity, or a contract that both: (i)&amp;#xA0;imposes on one
 entity a contractual obligation either to deliver cash or another
 financial instrument to a second entity or to exchange other
 financial instruments on potentially unfavorable terms with the
 second entity and (ii)&amp;#xA0;conveys to that second entity a
 contractual right either to receive cash or another financial
 instruments from the first entity or to exchange other financial
 instruments on potentially favorable terms with the first entity.
 This pronouncement is effective for financial statements issued for
 annual periods beginning after December&amp;#xA0;15, 2017 and interim
 periods within those annual periods with earlier application
 permitted as of the beginning of the fiscal year of adoption. The
 Company is evaluating the impact that this new guidance will have
 on the Company&amp;#x2019;s Consolidated Financial
 Statements.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Other than the
 pronouncements discussed above, there are no recently issued
 pronouncements that the Company has not already adopted or that
 have a material impact on the Company.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;&lt;b&gt;Subsequent Events
 &amp;#x2013;&lt;/b&gt; The Company has evaluated all events or transactions
 through the date of this filing.&amp;#xA0;During this period the
 Company did not have any material subsequent events that impacted
 its unaudited consolidated financial statements.&lt;/font&gt;&lt;/p&gt;

 &lt;p style="margin-top:6px;margin-bottom:0px"&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;The Company filed its tax
 returns for the year ended December&amp;#xA0;31, 2016 with the Internal
 Revenue Service in September 2017 and generated additional federal
 net operating loss (NOL) carryforward assets principally due to
 current tax repair deductions, tax depreciation and research and
 development deductions. As of September&amp;#xA0;30, 2017, the Company
 had recorded cumulative federal and state NOL carryforward assets
 of $23.9&amp;#xA0;million to offset against taxes payable in future
 periods. If unused, the Company&amp;#x2019;s NOL carryforward assets
 will begin to expire in 2029. In addition, at September&amp;#xA0;30,
 2017, the Company had $3.4&amp;#xA0;million of cumulative alternative
 minimum tax credits, general business tax credit and other state
 tax credit carryforwards to offset future income taxes
 payable.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="margin-top:12px;margin-bottom:0px"&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;The Company evaluated its
 tax positions at September&amp;#xA0;30, 2017 in accordance with the
 FASB Codification, and has concluded that no adjustment for
 recognition, derecognition, settlement and foreseeable future
 events to any tax liabilities or assets as defined by the FASB
 Codification is required. The Company remains subject to
 examination by Federal, Maine, Massachusetts, and New Hampshire tax
 authorities for the tax periods ended December&amp;#xA0;31,
 2014;&amp;#xA0;December&amp;#xA0;31, 2015; and December&amp;#xA0;31, 2016. The
 Company received notice that its Maine income tax return filings
 for the years ended December&amp;#xA0;31, 2014;&amp;#xA0;December&amp;#xA0;31,
 2015; and December&amp;#xA0;31, 2016 are under examination by the Maine
 Revenue Service. Auditor fieldwork is scheduled to occur in the
 fourth quarter of 2017 and the Company does not expect that the
 results of this examination will have a material impact on its
 financial position, operating results or cash flows.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="margin-top:12px;margin-bottom:0px"&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;The Company bills its
 customers for sales tax in Massachusetts and Maine and consumption
 tax in New Hampshire. These taxes are remitted to the appropriate
 departments of revenue in each state and are excluded from revenues
 on the Company&amp;#x2019;s unaudited Consolidated Statements of
 Earnings.&lt;/font&gt;&lt;/p&gt;

 &amp;#x2013;&lt;/b&gt; The Company&amp;#x2019;s principal business is the
 distribution of electricity and natural gas by the three
 distribution utilities: Unitil Energy, Fitchburg and Northern
 Utilities. Unitil Energy and Fitchburg are subject to regulation by
 the FERC. Fitchburg is also regulated by the Massachusetts
 Department of Public Utilities (MDPU), Unitil Energy is regulated
 by the New Hampshire Public Utilities Commission (NHPUC) and
 Northern Utilities is regulated by the Maine Public Utilities
 Commission (MPUC) and NHPUC. Granite State, the Company&amp;#x2019;s
 natural gas transmission pipeline, is regulated by the FERC.
 Accordingly, the Company uses the Regulated Operations guidance as

 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Generally, the Company
 receives a return on investment on its regulated assets for which a
 cash outflow has been made. Included in Regulatory Assets as of
 September&amp;#xA0;30, 2017 are $1.4 million of deferred storm charges
 to be recovered over the next year and $7.4 million of
 environmental costs, rate case costs and other expenditures to be
 recovered over varying periods in the next seven years. Regulators
 have authorized recovery of these expenditures, but without a
 return. Regulatory commissions can reach different conclusions
 about the recovery of costs, which can have a material impact on
 the Company&amp;#x2019;s Consolidated Financial Statements. The Company
 believes it is probable that its regulated distribution and
 transmission utilities will recover their investments in long-lived
 assets, including regulatory assets. If the Company, or a portion
 of its assets or operations, were to cease meeting the criteria for
 application of these accounting rules, accounting standards for
 businesses in general would become applicable and immediate
 recognition of any previously deferred costs, or a portion of
 deferred costs, would be required in the year in which the criteria
 are no longer met, if such deferred costs were not recoverable in
 the portion of the business that continues to meet the criteria for
 application of the FASB Codification topic on Regulated Operations.
 If unable to continue to apply the FASB Codification provisions for
 Regulated Operations, the Company would be required to apply the
 provisions for the Discontinuation of Rate-Regulated Accounting
 included in the FASB Codification. In the Company&amp;#x2019;s opinion,
 its regulated operations will be subject to the FASB Codification
 provisions for Regulated Operations for the foreseeable
 future.&lt;/font&gt;&lt;/p&gt;

 Debt&lt;/b&gt; &amp;#x2013; Currently, the Company believes that there is no
 active market in the Company&amp;#x2019;s debt securities, which have
 all been sold through private placements. If there were an active
 market for the Company&amp;#x2019;s debt securities, the fair value of
 the Company&amp;#x2019;s long-term debt would be estimated based on the
 quoted market prices for the same or similar issues, or on the
 current rates offered to the Company for debt of the same remaining
 maturities. The fair value of the Company&amp;#x2019;s long-term debt is
 estimated using Level 2 inputs (valuations based on quoted prices
 available in active markets for similar assets or liabilities,
 quoted prices for identical or similar assets or liabilities in
 inactive markets, inputs other than quoted prices that are directly
 observable, and inputs derived principally from market data.) In
 estimating the fair value of the Company&amp;#x2019;s long-term debt,
 the assumed market yield reflects the Moody&amp;#x2019;s Baa Utility
 Bond Average Yield. Costs, including prepayment costs, associated
 with the early settlement of long-term debt are not taken into
 consideration in determining fair value.&lt;/font&gt;&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 6px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;On October&amp;#xA0;4, 2013,
 the Company entered into an Amended and Restated Credit Agreement
 (as further amended, restated, amended and restated, modified or
 supplemented from time to time, the &amp;#x201C;Credit Facility&amp;#x201D;).
 The Credit Facility terminates October&amp;#xA0;4, 2020 and provides
 for a borrowing limit of $120 million which includes a $25 million
 sublimit for the issuance of standby letters of credit. The Credit
 Facility provides Unitil with the ability to elect that borrowings
 under the Credit Facility bear interest under several options,
 including at a daily fluctuating rate of interest per annum equal
 to one-month London Interbank Offered Rate (LIBOR) plus 1.25%.
 Provided there is no event of default under the Credit Facility,
 the Company may on a one-time basis request an increase in the
 aggregate commitments under the Credit Facility by an aggregate
 additional amount of up to $30 million.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Company utilizes the
 Credit Facility for cash management purposes related to its
 short-term operating activities. Total gross borrowings were $164.2
 million for the nine months ended September&amp;#xA0;30, 2017. Total
 gross repayments were $134.2 million for the nine months ended
 September&amp;#xA0;30, 2017. The following table details the borrowing
 limits, amounts outstanding and amounts available under the
 revolving Credit Facility as of September&amp;#xA0;30,
 2017,&amp;#xA0;September&amp;#xA0;30, 2016 and December&amp;#xA0;31,
 2016:&lt;/font&gt;&lt;/p&gt;

 this type, including affirmative and negative covenants. There are
 restrictions on, among other things, Unitil Corporation&amp;#x2019;s and
 its subsidiaries&amp;#x2019; ability to permit liens or incur
 indebtedness, and restrictions on Unitil&amp;#x2019;s ability to merge

 The affirmative and negative covenants under the Credit Facility
 shall apply until the Credit Facility terminates and all amounts
 borrowed under the Credit Facility are paid in full (or with
 respect to letters of credit, they are cash collateralized). The
 only financial covenant in the Credit Facility provides that Funded
 Debt to Capitalization (as each term is defined in the Credit

 million of Notes due 2027 at 3.52% and $30 million of Notes due
 2047 at 4.32%. Fitchburg priced $10 million of Notes due 2027 at
 3.52% and $15 million of Notes due 2047 at 4.32%.&amp;#xA0;Granite
 State priced $15 million of Notes due 2027 at 3.72%. Northern
 Utilities, Fitchburg and Granite State plan to use the net proceeds
 from the offering to repay short-term debt and for general
 corporate purposes and anticipate closing and funding this
 long-term financing on November&amp;#xA0;1, 2017. However, the issuance
 of the Notes is subject to customary closing conditions for a
 transaction of this type. The Notes offered have not been and will
 not be registered under the Securities Act of 1933 (Act), or any
 state securities laws, and may not be offered or sold in the United
 States absent registration or an applicable exemption from the
 registration requirements of the Act and applicable state
 securities laws. As of September&amp;#xA0;30, 2017, the Company has
 deferred $0.1 million of costs associated with this
 financing.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;In April 2014, Unitil
 Service entered into a financing arrangement, structured as a
 capital lease obligation, for various information systems and
 technology equipment. Final funding under this capital lease
 occurred on October&amp;#xA0;30, 2015, resulting in total funding of
 $13.4 million. The capital lease matures on September&amp;#xA0;30,
 2020. As of September&amp;#xA0;30, 2017, there are $2.7 million of
 current and $5.8 million of noncurrent obligations under this
 capital lease on the Company&amp;#x2019;s Consolidated Balance
 Sheets.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Northern Utilities enters
 into asset management agreements under which Northern Utilities
 releases certain natural gas pipeline and storage assets, resells
 the natural gas storage inventory to an asset manager and
 subsequently repurchases the inventory over the course of the
 natural gas heating season at the same price at which it sold the
 natural gas inventory to the asset manager. There was $9.0 million,
 $9.3 million and $9.9 million of natural gas storage inventory at
 September&amp;#xA0;30, 2017,&amp;#xA0;September 30, 2016 and
 December&amp;#xA0;31, 2016, respectively, related to these asset
 management agreements. The amount of natural gas inventory released
 in September 2017 and payable in October 2017 is $0.1 million and
 is recorded in Accounts Payable at September&amp;#xA0;30, 2017. The
 amount of natural gas inventory released in September 2016 and
 payable in October 2016 was $0.1 million and is recorded in
 Accounts Payable at September&amp;#xA0;30, 2016. The amount of natural
 gas inventory released in December 2016 and payable in January 2017
 was $2.1 million and was recorded in Accounts Payable at
 December&amp;#xA0;31, 2016.&lt;/font&gt;&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 6px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Company provides
 limited guarantees on certain energy and natural gas storage
 management contracts entered into by the distribution utilities.
 The Company&amp;#x2019;s policy is to limit the duration of these
 guarantees. As of September&amp;#xA0;30, 2017, there were approximately
 $19.8 million of guarantees outstanding and the longest term
 guarantee extends through August 2018.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Company also guarantees
 the payment of principal, interest and other amounts payable on the
 notes issued by Granite State. As of September&amp;#xA0;30, 2017, the
 principal amount outstanding for the 7.15% Granite State notes was
 $6.7 million.&lt;/font&gt;&lt;/p&gt;

 ENVIRONMENTAL MATTERS ARE DESCRIBED IN NOTE 8 TO THE FINANCIAL
 STATEMENTS IN ITEM&amp;#xA0;8 OF PART II OF UNITIL CORPORATION&amp;#x2019;S
 FORM 10-K FOR DECEMBER&amp;#xA0;31, 2016 AS FILED WITH THE SECURITIES

 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 6px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Company&amp;#x2019;s past
 and present operations include activities that are generally
 subject to extensive and complex federal and state environmental
 laws and regulations. The Company is in material compliance with
 applicable environmental and safety laws and regulations and, as of
 September&amp;#xA0;30, 2017, has not identified any material losses
 reasonably likely to be incurred in excess of recorded amounts.
 However, we cannot assure that significant costs and liabilities
 will not be incurred in the future. It is possible that other
 developments, such as increasingly stringent federal, state or
 local environmental laws and regulations could result in increased
 environmental compliance costs. Based on the Company&amp;#x2019;s
 current assessment of its environmental responsibilities, existing
 legal requirements and regulatory policies, the Company does not
 believe that these environmental costs will have a material adverse
 effect on the Company&amp;#x2019;s consolidated financial position or
 results of operations.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;&lt;b&gt;Northern Utilities
 Manufactured Gas Plant Sites &amp;#x2013;&lt;/b&gt; Northern Utilities has an
 extensive program to identify, investigate and remediate former
 manufactured gas plant (MGP) sites, which were operated from the
 mid-1800s through the mid-1900s. In New Hampshire, MGP sites were
 identified in Dover, Exeter, Portsmouth, Rochester and Somersworth.
 In Maine, Northern Utilities has documented the presence of MGP
 sites in Lewiston and Portland, and a former MGP disposal site in
 Scarborough.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 12px"&gt;
 &amp;#xA0;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 0px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Northern Utilities has
 worked with the Maine Department of Environmental Protection (ME
 DEP) and New Hampshire Department of Environmental Services (NH
 DES) to address environmental concerns with these sites. Northern
 Utilities or others have substantially completed remediation of the
 Exeter, Rochester, Dover, Somersworth, Portsmouth, Lewiston,
 Portland and Scarborough sites, though on site monitoring continues
 and it is possible that future activities may be
 required.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The NHPUC and MPUC have
 approved regulatory mechanisms for the recovery of MGP
 environmental costs. For Northern Utilities&amp;#x2019; New Hampshire
 division, the NHPUC has approved the recovery of MGP environmental
 costs over succeeding seven-year periods. For Northern
 Utilities&amp;#x2019; Maine division, the MPUC has authorized the
 recovery of environmental remediation costs over succeeding
 five-year periods.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Environmental
 Obligations table below shows the amounts accrued for Northern
 Utilities related to estimated future cleanup costs associated with
 Northern Utilities&amp;#x2019; environmental remediation obligations for
 former MGP sites. Corresponding Regulatory Assets were recorded to
 reflect that the future recovery of these environmental remediation
 costs is expected based on regulatory precedent and established
 practices.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;&lt;b&gt;Fitchburg&amp;#x2019;s
 Manufactured Gas Plant Site &amp;#x2013;&lt;/b&gt; Fitchburg has worked with
 the Massachusetts Department of Environmental Protection (MA DEP)
 to address environmental concerns with the former MGP site at
 Sawyer Passway, and has substantially completed remediation
 activities, though on site monitoring will continue and it is
 possible that future activities may be required.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Environmental
 Obligations table below shows the amounts accrued for Fitchburg
 related to estimated future cleanup costs for permanent remediation
 of the Sawyer Passway site with a corresponding Regulatory Asset
 recorded to reflect that the recovery of these environmental
 remediation costs are probable through the regulatory process. The
 amounts recorded do not assume any amounts are recoverable from
 insurance companies or other third parties. Fitchburg recovers the
 environmental response costs incurred at this former MGP site in
 gas rates pursuant to the terms of a cost recovery agreement
 approved by the MDPU. Pursuant to this agreement, Fitchburg is
 authorized to amortize and recover environmental response costs
 from gas customers over succeeding seven-year periods.&lt;/font&gt;&lt;/p&gt;

 Base Rates&lt;/b&gt; &amp;#x2013; On April&amp;#xA0;20, 2017 the NHPUC issued its
 final order approving a settlement between Unitil Energy,
 Commission Staff and the Office of Consumer Advocate providing for
 a permanent increase of $4.1 million in electric base rates, and a
 three year rate plan with an additional rate step adjustment in May
 2017 of $0.9 million, followed by two rate step adjustments in May
 of 2018 and 2019 to recover the revenue requirements associated
 with annual capital expenditures as defined under the rate
 plan.&lt;/font&gt;&lt;/p&gt;

 issued an order approving a $2.1&amp;#xA0;million increase in
 Fitchburg&amp;#x2019;s electric base revenue decoupling target,
 effective May&amp;#xA0;1, 2016. As part of its order, the MDPU
 approved, with modifications, Fitchburg&amp;#x2019;s request for an
 annual capital cost recovery mechanism, which allows for increases
 to target revenues to recover the revenue requirement associated
 with annual capital additions as defined under the mechanism. In
 2016, Fitchburg made its first capital cost adjustment filing for
 calendar year 2015 capital investments, and received MDPU approval
 to increase revenues by approximately $0.5 million, subject to
 further investigation and reconciliation. On June&amp;#xA0;29, 2017,
 Fitchburg filed its compliance report on capital investments for
 calendar year 2016, which forms the basis for the next filing to
 adjust target revenues to be made with the MDPU in November 2017.
 These matters remain pending.&lt;/font&gt;&lt;/p&gt;

 Rates &amp;#x2013; Gas &amp;#x2013;&lt;/b&gt; On April&amp;#xA0;29, 2016, the MDPU
 issued an order approving a $1.6&amp;#xA0;million increase in
 Fitchburg&amp;#x2019;s gas base revenue decoupling target, effective
 May&amp;#xA0;1, 2016.&lt;/font&gt;&lt;/p&gt;

 Operations &amp;#x2013;&lt;/b&gt; On October&amp;#xA0;31, 2016, Fitchburg
 submitted its annual filing under its gas system enhancement
 program to recover the revenue requirements associated with capital
 additions in 2017 as defined under the program. The filing sought
 approval to collect an additional $0.9&amp;#xA0;million of annual
 revenues. On April&amp;#xA0;28, 2017, the MDPU approved recovery of
 2017 costs, subject to a revenue cap of 1.5%, resulting in an
 additional $0.5 million of annual revenues effective May&amp;#xA0;1,
 2017. The remaining $0.4 million of annual revenues the Company
 sought approval to collect has been deferred for recovery in future
 periods under the program. The Company has requested that the MDPU
 waive the 1.5% revenue requirement cap on deferred amounts. This
 matter remains pending.&lt;/font&gt;&lt;/p&gt;

 &lt;p style="margin-top:0px;margin-bottom:0px"&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;&lt;b&gt;Northern Utilities
 &amp;#x2013; Base Rates &amp;#x2013; Maine &amp;#x2013;&lt;/b&gt; On May&amp;#xA0;31, 2017,
 Northern Utilities filed a base rate case with the MPUC seeking to
 increase annual revenues by $6.0 million. On August&amp;#xA0;18, 2017,
 the Company made a supplemental filing seeking to increase revenues
 by an additional $0.7 million associated with its Targeted Area
 Build-out Program (see below). Following an extensive regulatory
 review and investigation process, a final order from the MPUC on
 Northern Utilities&amp;#x2019; request is expected by the end of
 February 2018.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="margin-top:12px;margin-bottom:0px"&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;In addition to the
 distribution base rate increase, Northern Utilities is requesting
 to extend its Targeted Infrastructure Replacement Adjustment
 mechanism (TIRA). The TIRA is a capital cost recovery mechanism
 designed to recover the annual revenue requirements associated with
 targeted investments in gas distribution system infrastructure
 replacement and upgrade projects, including the Company&amp;#x2019;s
 Cast Iron Replacement Program (CIRP). This matter remains
 pending.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="margin-top:12px;margin-bottom:0px"&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;&lt;b&gt;Northern Utilities
 &amp;#x2013; Targeted Infrastructure Replacement Adjustment &amp;#x2013;&lt;/b&gt;
 The settlement in Northern Utilities&amp;#x2019; Maine division&amp;#x2019;s
 last rate case allowed the Company to implement a TIRA rate
 mechanism to adjust base distribution rates annually to recover the
 revenue requirements associated with targeted investments in gas
 distribution system infrastructure replacement and upgrade
 projects. The TIRA had an initial term of four years and covers
 targeted capital expenditures in 2013 through 2016 as defined under
 the mechanism. The 2017 TIRA, for 2016 expenditures, was approved
 by the MPUC on April&amp;#xA0;25, 2017, and provided for an annual
 increase in distribution base revenue of $1.1&amp;#xA0;million,
 effective May&amp;#xA0;1, 2017.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="margin-top:12px;margin-bottom:0px"&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;&lt;b&gt;Northern Utilities
 &amp;#x2013; Targeted Area Build-out Program &amp;#x2013; Maine &amp;#x2013;&lt;/b&gt;
 On December&amp;#xA0;22, 2015, the MPUC approved a Targeted Area
 Build-out (TAB) program and associated rate surcharge mechanism.
 This program is designed to allow the economic extension of natural
 gas mains to new, targeted service areas in Maine. It allows
 customers in the targeted area the ability to pay a rate surcharge,
 instead of a large upfront payment or capital contribution to
 connect to the natural gas delivery system. The initial pilot of
 the TAB program was approved for the City of Saco, and is being
 built out over a period of three years, with the potential to add
 1,000 new customers and approximately $1&amp;#xA0;million in annual
 distribution revenue in the Saco area. The second TAB program was
 approved for the Town of Sanford, and has the potential to add
 2,000 new customers and approximately $2 million in annual
 distribution revenue in the Sanford area.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="margin-top:12px;margin-bottom:0px"&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;&lt;b&gt;Northern Utilities
 &amp;#x2013; Base Rates &amp;#x2013; New Hampshire &amp;#x2013;&lt;/b&gt; On
 June&amp;#xA0;5, 2017, Northern Utilities filed for a base rate
 increase with the NHPUC seeking to increase annual revenues by $4.7
 million. On June&amp;#xA0;15, 2017, the Commission suspended the
 Company&amp;#x2019;s proposed permanent rates tariffs while the filing
 is under extensive regulatory review and investigation over the
 next several months. A final order from the NHPUC on Northern
 Utilities&amp;#x2019; request is expected in the second quarter of
 2018.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="margin-top:12px;margin-bottom:0px"&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;Northern Utilities reached a
 settlement agreement on temporary rates to produce an increase in
 annual revenues of approximately $1.6 million, effective with
 service rendered on and after August&amp;#xA0;1, 2017, and until a
 final, non-appealable order on permanent rates is issued. As of
 September&amp;#xA0;30, 2017, Northern Utilities has deferred
 approximately $0.3 million of costs associated with this base rate
 case. Once a final decision on permanent rates is issued, it will
 be reconciled back to the date that temporary rates were
 implemented. The settlement agreement was approved by the
 Commission on July&amp;#xA0;31, 2017.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="margin-top:12px;margin-bottom:0px"&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;In its initial petition,
 Northern Utilities requested approval to implement a multi-year
 rate plan, including a capital cost recovery mechanism, which will
 allow for recovery of the revenue requirements associated with
 future annual capital expenditures as defined under the plan
 through changes, or step adjustments, to Northern Utilities&amp;#x2019;
 distribution rates without the need to file a general rate case
 prior to January 2021. This matter remains pending.&lt;/font&gt;&lt;/p&gt;

 &amp;#x2013; Pipeline Refund &amp;#x2013;&lt;/b&gt; On February&amp;#xA0;19, 2015, the
 FERC issued Opinion No.&amp;#xA0;524-A, the final order in Portland
 Natural Gas Transmission&amp;#x2019;s (PNGTS) Section&amp;#xA0;4 rate case,
 requiring PNGTS to issue refunds to shippers. Northern Utilities
 received a pipeline refund of $22.0&amp;#xA0;million on April&amp;#xA0;15,
 2015. As a gas supply-related refund, the entire amount refunded
 will be credited to Northern Utilities&amp;#x2019; customers and
 marketers over three years as directed by the NHPUC and MPUC. The
 Company has recorded current Regulatory Liabilities related to
 these refunds of $3.4&amp;#xA0;million on its Consolidated Balance
 Sheets as of September&amp;#xA0;30, 2017.&lt;/font&gt;&lt;/p&gt;

 Base Rates &amp;#x2013;&lt;/b&gt; Granite State has in place a FERC-approved
 second amended settlement agreement under which it is permitted to
 file annually, each June, for a rate adjustment to recover the
 revenue requirements associated with specified capital investments
 in gas transmission projects up to a specific cap on expenditures.
 On June&amp;#xA0;21, 2017 Granite State filed for an annual revenue
 increase under this provision of $0.2&amp;#xA0;million, effective
 August&amp;#xA0;1, 2017. The FERC issued an order approving the filing
 on July&amp;#xA0;28, 2017. This is the last annual rate adjustment
 allowed under the second amended settlement.&lt;/font&gt;&lt;/p&gt;

 Resource Standard Proceeding &amp;#x2013;&lt;/b&gt; In May 2015, the NHPUC
 opened a proceeding to establish an Energy Efficiency Resource
 Standard (&amp;#x201C;EERS&amp;#x201D;), an energy efficiency policy with
 specific targets or goals for energy savings that New Hampshire
 electric and gas utilities must meet. On April&amp;#xA0;27, 2016, a
 comprehensive settlement agreement was filed by the parties,
 including Unitil Energy and Northern Utilities, which was approved
 by the NHPUC on August&amp;#xA0;2, 2016. The settlement provides for:
 extending the 2014-2016 Core program an additional year (through
 2017); establishing an EERS; establishing a recovery mechanism to
 compensate the utilities for lost-revenue related to the EERS
 programs; and approving the performance incentives and processes
 for stakeholder involvement, evaluation, measurement and
 verification, and oversight of the EERS programs. In accordance
 with the Settlement, on September&amp;#xA0;1, 2017, the New Hampshire
 electric and gas utilities jointly filed a Statewide Energy
 Efficiency Plan for the period 2018-2020. This filing remains
 pending.&lt;/font&gt;&lt;/p&gt;

 Electric Grid Modernization &amp;#x2013;&lt;/b&gt; In July 2015, the NHPUC
 opened an investigation into Grid Modernization to address a
 variety of issues related to Distribution System Planning, Customer
 Engagement with Distributed Energy Resources, and Utility Cost
 Recovery and Financial Incentives. The NHPUC engaged a consultant
 to direct a Working Group to investigate these issues and to
 prepare a final report with recommendations for the Commission. The
 final report was filed on March&amp;#xA0;20, 2017. This matter remains
 pending.&lt;/font&gt;&lt;/p&gt;

 Metering &amp;#x2013;&lt;/b&gt; Pursuant to legislation that became effective
 in May 2016, the NHPUC opened a proceeding to consider alternatives
 to the net metering tariffs currently in place. The NHPUC issued an
 Order on June&amp;#xA0;23, 2017. The Order removes the cap on the total
 amount of generation capacity which may be owned or operated by
 customer-generators eligible for net metering. The order also
 adopts an alternative net metering tariff for small
 customer-generators (those with renewable energy systems of 100 kW
 or less) which will remain in effect for a period of years while
 further data is collected and analyzed, time-of-use and other pilot
 programs are implemented, and a distributed energy resource
 valuation study is conducted. Systems that are installed or queued
 during this period will have their net metering rate structure
 &amp;#x201C;grandfathered&amp;#x201D; until December&amp;#xA0;31, 2040. The
 Company does not believe that this proceeding will have a material
 adverse impact on the Company&amp;#x2019;s financial position, operating
 results or cash flows.&lt;/font&gt;&lt;/p&gt;

 Electric Operations &amp;#x2013;&lt;/b&gt; On November&amp;#xA0;17, 2016,
 Fitchburg submitted its 2016 annual reconciliation of costs and
 revenues for transition and transmission under its restructuring
 plan, including the reconciliation of costs and revenues for a
 number of other surcharges and cost factors, for review and
 approval by the MDPU. All of the rates were given final approval by
 the MDPU on December&amp;#xA0;29, 2016, effective January&amp;#xA0;1,
 2017.&lt;/font&gt;&lt;/p&gt;

 its 2016 Service Quality Reports for both its gas and electric
 divisions in accordance with new Service Quality Guidelines issued
 by the MDPU in December 2015. Fitchburg reported that it met or
 exceeded its benchmarks for service quality performance in all
 metrics for both its gas and electric divisions. This matter

 Generation &amp;#x2013;&lt;/b&gt; On August&amp;#xA0;19, 2016, Fitchburg filed a
 petition with the MDPU seeking approval to develop a 1.3 MW solar
 generation facility located on Company property in Fitchburg,
 Massachusetts, including a cost recovery mechanism to share the
 costs and benefits of the project among all Fitchburg customers. On
 November&amp;#xA0;9, 2016, the MDPU approved a Settlement Agreement
 supporting the proposal, which was reached among the Company, the
 Attorney General of Massachusetts, and the Low-Income
 Weatherization and Fuel Assistance Program Network. Construction of
 the solar generating facility is expected to be completed by the
 end of November 2017.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="margin-top:12px;margin-bottom:0px"&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;&lt;b&gt;Fitchburg &amp;#x2013; Energy
 Diversity &amp;#x2013;&lt;/b&gt; Governor Baker signed into law H4568
 &amp;#x201C;An Act to Promote Energy Diversity&amp;#x201D; on August&amp;#xA0;8,
 2016. Among many sections in the bill, the primary provision adds
 new sections 83c and 83d to the 2008 Green Communities Act.
 Section&amp;#xA0;83c requires every electric distribution company
 (EDC), including Fitchburg, to jointly and competitively solicit
 proposals for at least 400 MW&amp;#x2019;s of offshore wind energy
 generation by June&amp;#xA0;30, 2017, as part of a total of 1,600 MW of
 offshore wind the EDCs are directed to procure by June&amp;#xA0;30,
 2027. The procurement requirement is subject to a determination by
 the MDPU that the proposed long-term contracts are cost-effective.
 Section&amp;#xA0;83d further requires the EDCs to jointly seek
 proposals for cost effective clean energy (hydro and other)
 long-term contracts via one or more staggered solicitations, the
 first of which shall be issued not later than April&amp;#xA0;1, 2017,
 for a total of 9,450,000 megawatt-hours by December&amp;#xA0;31, 2022.
 Emergency regulations implementing these new provisions, 220 C.M.R.
 &amp;#xA7; 23.00 et seq. and 220 C.M.R. &amp;#xA7; 24.00 et seq. were
 adopted by the MDPU on December&amp;#xA0;29, 2016, and adopted as final
 regulations on March&amp;#xA0;8, 2017. The EDCs issued the RFP for
 Long-Term Contracts for Clean Energy Projects, pursuant to
 Section&amp;#xA0;83d on March&amp;#xA0;31, 2017 and project proposals were
 received on July&amp;#xA0;27, 2017. The EDCs issued the RFP for
 Long-Term Contracts for Offshore Wind Energy Projects pursuant to
 Section&amp;#xA0;83c on June&amp;#xA0;29, 2017.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="margin-top:12px;margin-bottom:0px"&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;&lt;b&gt;Fitchburg &amp;#x2013; Clean
 Energy RFP &amp;#x2013;&lt;/b&gt; Pursuant to Section&amp;#xA0;83a of the Green
 Communities Act in Massachusetts and similar clean energy
 directives established in Connecticut and Rhode Island, state
 agencies and the electric distribution companies in the three
 states, including Fitchburg, issued an RFP for clean energy
 resources (including Class&amp;#xA0;I renewable generation and large
 hydroelectric generation) in November 2015. The RFP sought
 proposals for clean energy and transmission projects that can
 deliver new renewable energy to the three states. Project proposals
 were received in January 2016. Selection of contracts concluded
 during the fourth quarter of 2016 and contract negotiations
 concluded during the second quarter of 2017. On September&amp;#xA0;20,
 2017, Fitchburg, along with the other three EDCs, filed for
 approval of the purchase power agreements which were negotiated as
 a result of the joint solicitation. This matter remains
 pending.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="margin-top:12px;margin-bottom:0px"&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;&lt;b&gt;Fitchburg &amp;#x2013; Other
 &amp;#x2013;&lt;/b&gt; On August&amp;#xA0;25, 2017, the Massachusetts Department
 of Energy Resources&amp;#x2019; (&amp;#x201C;DOER&amp;#x201D;) Solar Massachusetts
 Renewable Target (SMART) Program regulations were finalized. These
 regulations were promulgated pursuant to Chapter 75 of the Acts of
 2016, which required the DOER to establish a new solar incentive
 program. The regulation is designed to support the continued
 development of an additional 1,600 MW of solar renewable energy
 generating sources via a declining block compensation mechanism,
 and is the product of an extensive stakeholder process that began
 last spring and involved over 40 public meetings and two written
 public comment periods. On September&amp;#xA0;12, 2017, the
 Massachusetts electric utilities jointly filed a model SMART tariff
 with the MDPU to implement the program and propose a cost recovery
 mechanism. This filing remains pending. In the interim, the current
 program for solar renewable energy credits, known as SREC-II,
 remains in effect for all eligible solar facilities.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="font-size:1px;margin-top:12px;margin-bottom:0px"&gt;
 &amp;#xA0;&lt;/p&gt;
 &lt;p style="margin-top:0px;margin-bottom:0px"&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;On May&amp;#xA0;11, 2016, the
 MDPU issued an Order commencing a rulemaking proceeding to adopt
 emergency regulations amending 220 C.M.R. &amp;#xA7; 18.00 et seq.
 (&amp;#x201C;Net Metering Regulations&amp;#x201D;). Specifically, the MDPU
 amended its Net Metering Regulations to implement the net metering
 provisions of An Act Relative to Solar Energy, St. 2016, c. 75,
 &amp;#xA7;&amp;#xA7; 3-9, and to make additional clerical changes to the
 Net Metering Regulations. On July&amp;#xA0;15, 2016, the MDPU issued an
 order approving Final Net Metering Regulations. Fitchburg&amp;#x2019;s
 tariff, filed in compliance with the new regulations, was approved
 on February&amp;#xA0;7, 2017.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="margin-top:12px;margin-bottom:0px"&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;In December&amp;#xA0;2013, the
 MDPU opened an investigation into Modernization of the Electric
 Grid. The stated objective of the Grid Modernization proceeding is
 to ensure that the electric distribution companies &amp;#x201C;adopt
 grid modernization policies and practices.&amp;#x201D; In
 June&amp;#xA0;2014, the MDPU issued its first Grid Modernization order,
 setting forth a requirement that each electric distribution company
 submit a ten-year strategic Grid Modernization Plan (GMP). As part
 of the GMP, each company must include a five-year Short-Term
 Investment Plan (STIP), which must include an approach to achieving
 advanced metering functionality within five years of the
 Department&amp;#x2019;s approval of the GMP. The filing of a GMP is a
 recurring obligation and must be updated as part of subsequent base
 distribution rate cases, which by statute must occur no less often
 than every five years. Capital investments contained in the STIP
 are eligible for pre-authorization, meaning that the MDPU will not
 revisit in later filings whether the Company should have proceeded
 with these investments. Fitchburg and the Commonwealth&amp;#x2019;s
 three other electric distribution companies filed their initial
 GMPs on August&amp;#xA0;19, 2015. These filings are currently under
 MDPU review and remain pending.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="margin-top:12px;margin-bottom:0px"&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;On January&amp;#xA0;28, 2016 the
 MDPU approved Fitchburg&amp;#x2019;s Three-Year Energy Efficiency Plan
 for 2016-2018, subject to limited modifications and directives in
 the Order. The Department found that the savings goals included in
 each Three-Year Plan are reasonable and are consistent with the
 achievement of all available cost-effective energy efficiency;
 approved each Program Administrator&amp;#x2019;s program implementation
 cost budget for the Three-Year Plans; approved the performance
 incentive pool, mechanism, and payout rates; found that all
 proposed energy efficiency programs are cost-effective; found that
 funding sources are reasonable and that each Program Administrator
 may recover the funds to implement its energy efficiency plan
 through its Energy Efficiency Surcharge; and found that each
 Program Administrator&amp;#x2019;s Three-Year Plan is consistent with
 the Green Communities Act, the Guidelines, and Department
 precedent.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="margin-top:12px;margin-bottom:0px"&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;&lt;b&gt;FERC Transmission Formula
 Rate Proceedings &amp;#x2013;&lt;/b&gt; Pursuant to Section&amp;#xA0;206 of the
 Federal Power Act, there are several pending proceedings before the
 FERC concerning the justness and reasonableness of the Return on
 Equity (&amp;#x201C;ROE&amp;#x201D;) component of the ISO-New England, Inc.
 Participating Transmission Owners&amp;#x2019; Regional Network Service
 and Local Network Service formula rates. On April&amp;#xA0;14, 2017,
 the U.S. Court of Appeals for the D.C. Circuit issued an opinion
 vacating a decision of the FERC with respect to these formula
 rates, and remanded it for further proceedings. The FERC had found
 that the Transmission Owners existing ROE was unlawful, and had set
 a new ROE. The Court found that the FERC had failed to articulate a
 satisfactory explanation for its orders. At this time, the ROE set
 in the vacated order will remain in place until further FERC action
 is taken. Fitchburg and Unitil Energy are Participating
 Transmission Owners, although Unitil Energy does not own
 transmission plant. To the extent that these proceedings result in
 any changes to the rates being charged, a retroactive
 reconciliation may be required. The Company does not believe that
 these proceedings will have a material adverse impact on the
 Company&amp;#x2019;s financial condition or results of
 operations.&lt;/font&gt;&lt;/p&gt;

 Proceedings&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
 &lt;p style="margin-top:6px;margin-bottom:0px"&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;The Company is involved in
 legal and administrative proceedings and claims of various types,
 which arise in the ordinary course of business. The Company
 believes, based upon information furnished by counsel and others,
 that the ultimate resolution of these claims will not have a
 material impact on its financial position, operating results or
 cash flows.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="margin-top:12px;margin-bottom:0px"&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;In early 2009, a putative
 class action complaint was filed against Unitil&amp;#x2019;s
 Massachusetts based utility, Fitchburg, in Massachusetts&amp;#x2019;
 Worcester Superior Court (the &amp;#x201C;Court&amp;#x201D;), (captioned
 Bellermann et al v. Fitchburg Gas and Electric Light Company). The
 Complaint seeks an unspecified amount of damages, including the
 cost of temporary housing and alternative fuel sources, emotional
 and physical pain and suffering and property damages allegedly
 incurred by customers in connection with the loss of electric
 service during the ice storm in Fitchburg&amp;#x2019;s service territory
 in December 2008. The Massachusetts Supreme Judicial Court issued
 an order denying class certification status in July 2016, though
 the plaintiffs&amp;#x2019; individual claims remain pending. The Company
 continues to believe that this suit is without merit and will
 continue to defend itself vigorously. Based upon information
 furnished by counsel and others, the Company believes that the
 ultimate resolution of this suit will not have a material impact on
 its financial position, operating results or cash flows. The Town
 of Lunenburg filed a separate action in the Court arising out of
 the December 2008 ice storm. The Court granted the Company&amp;#x2019;s
 Motion for Summary Judgment on all counts in December 2016 and
 dismissed the Town&amp;#x2019;s complaint. The Town filed a notice of
 appeal, but failed to perfect its appeal with the Court in a timely
 manner. A motion to dismiss for failure to perfect the appeal was
 granted by the Massachusetts Appeals Court in August
 2017.&lt;/font&gt;&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 6px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Company had
 14,060,147,14,065,230 and 14,119,893 shares of common stock
 outstanding at September&amp;#xA0;30, 2016,&amp;#xA0;December&amp;#xA0;31, 2016

 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;&lt;b&gt;Dividend Reinvestment
 and Stock Purchase Plan -&lt;/b&gt; During the first nine months of 2017,
 the Company sold 20,564 shares of its common stock, at an average
 price of $47.02 per share, in connection with its Dividend
 Reinvestment and Stock Purchase Plan (DRP) and its 401(k) plans
 resulting in net proceeds of approximately $967,000. The DRP
 provides participants in the plan a method for investing cash
 dividends on the Company&amp;#x2019;s common stock and cash payments in
 additional shares of the Company&amp;#x2019;s common stock.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;&lt;b&gt;Stock Plan -&lt;/b&gt; The
 Company maintains the Unitil Corporation Second Amended and
 Restated 2003 Stock Plan (the Stock Plan). Participants in the
 Stock Plan are selected by the Compensation Committee of the Board
 of Directors to receive awards under the Stock Plan, including
 awards of restricted shares (Restricted Shares), or of restricted
 stock units (Restricted Stock Units). The Compensation Committee
 has the authority to determine the sizes of awards; determine the
 terms and conditions of awards in a manner consistent with the
 Stock Plan; construe and interpret the Stock Plan and any agreement
 or instrument entered into under the Stock Plan as they apply to
 participants; establish, amend, or waive rules and regulations for
 the Stock Plan&amp;#x2019;s administration as they apply to
 participants; and, subject to the provisions of the Stock Plan,
 amend the terms and conditions of any outstanding award to the
 extent such terms and conditions are within the discretion of the
 Compensation Committee as provided for in the Stock Plan. On
 April&amp;#xA0;19, 2012, the Company&amp;#x2019;s shareholders approved an
 amendment to the Stock Plan to, among other things, increase the
 maximum number of shares of common stock available for awards to
 plan participants.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The maximum number of
 shares available for awards to participants under the Stock Plan is
 677,500. The maximum number of shares that may be awarded in any
 one calendar year to any one participant is 20,000. In the event of
 any change in capitalization of the Company, the Compensation
 Committee is authorized to make an equitable adjustment to the
 number and kind of shares of common stock that may be delivered
 under the Stock Plan and, in addition, may authorize and make an
 equitable adjustment to the Stock Plan&amp;#x2019;s annual individual
 award limit.&lt;/font&gt;&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 6px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Outstanding awards of
 Restricted Shares fully vest over a period of four years at a rate
 of 25% each year. During the vesting period, dividends on
 Restricted Shares underlying the award may be credited to a
 participant&amp;#x2019;s account. The Company may deduct or withhold, or
 require a participant to remit to the Company, an amount sufficient
 to satisfy any taxes required by federal, state, or local law or
 regulation to be withheld with respect to any taxable event arising
 in connection with an Award. For purposes of compensation expense,
 Restricted Shares vest immediately upon a participant becoming
 eligible for retirement, as defined in the Stock Plan. Prior to the
 end of the vesting period, the restricted shares are subject to
 forfeiture if the participant ceases to be employed by the Company
 other than due to the participant&amp;#x2019;s death.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;On January&amp;#xA0;30, 2017,
 34,930 Restricted Shares were issued in conjunction with the Stock
 Plan with an aggregate market value at the date of issuance of
 approximately $1.6 million. There were 89,326 and 95,506 non-vested
 shares under the Stock Plan as of September&amp;#xA0;30, 2017 and 2016,
 respectively. The weighted average grant date fair value of these
 shares was $39.54 and $35.30, respectively. The compensation
 expense associated with the issuance of shares under the Stock Plan
 is being recognized over the vesting period and was $2.6 million
 and $2.0 million for the nine months ended September&amp;#xA0;30, 2017
 and 2016, respectively. At September&amp;#xA0;30, 2017, there was
 approximately $1.0 million of total unrecognized compensation cost
 under the Stock Plan which is expected to be recognized over
 approximately 2.4 years. There were 831 Restricted Shares forfeited
 and no cancellations under the Stock Plan during the nine months
 ended September&amp;#xA0;30, 2017.&lt;/font&gt;&lt;/p&gt;

 the Company&amp;#x2019;s Board of Directors (Directors) may elect to
 receive the equity portion of their annual retainer in the form of
 Restricted Stock Units. Restricted Stock Units earn dividend
 equivalents and will generally be settled by payment to each
 Director as soon as practicable following the Director&amp;#x2019;s
 separation from service to the Company. The Restricted Stock Units
 will be paid such that the Director will receive (i)&amp;#xA0;70% of
 the shares of the Company&amp;#x2019;s common stock underlying the
 restricted stock units and (ii)&amp;#xA0;cash in an amount equal to the
 fair market value of 30% of the shares of the Company&amp;#x2019;s
 common stock underlying the Restricted Stock Units. The equity

 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;&lt;b&gt;Derivatives &amp;#x2013;&lt;/b&gt;
 The Company&amp;#x2019;s regulated energy subsidiaries enter into energy
 supply contracts to serve their electric and gas customers. The
 Company follows a procedure for determining whether each contract
 qualifies as a derivative instrument under the guidance provided by
 the FASB Codification on Derivatives and Hedging. For each
 contract, the Company reviews and documents the key terms of the
 contract. Based on those terms and any additional relevant
 components of the contract, the Company determines and documents
 whether the contract qualifies as a derivative instrument as
 defined in the FASB Codification. The Company has determined that
 none of its energy supply contracts, other than the regulatory
 approved hedging program, described below, qualifies as a
 derivative instrument under the guidance set forth in the FASB
 Codification.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Company has a
 regulatory approved hedging program for Northern Utilities designed
 to fix or cap a portion of its gas supply costs for the coming
 years of service. Under the program, the Company may purchase call
 option contracts on NYMEX natural gas futures contracts for future
 winter period months.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Any gains or losses
 resulting from the change in the fair value of these derivatives
 are passed through to ratepayers directly through Northern
 Utilities&amp;#x2019; Cost of Gas Clause. The fair value of these
 derivatives is determined using Level 2 inputs (valuations based on
 quoted prices in markets that are not active or for which all
 significant inputs are observable, either directly or indirectly),
 specifically based on the NYMEX closing prices for outstanding
 contracts as of the balance sheet date. As a result of the
 ratemaking process, the Company records gains and losses resulting
 from the change in fair value of the derivatives as regulatory
 liabilities or assets, then reclassifies these gains or losses into
 Cost of Gas Sales when the gains and losses are passed through to
 customers through the Cost of Gas Clause.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;As of September&amp;#xA0;30,
 2017,&amp;#xA0;September&amp;#xA0;30, 2016 and December&amp;#xA0;31, 2016 the
 Company had 1.2 billion, 2.9 billion and 2.0 billion cubic feet
 (BCF), respectively, outstanding in natural gas futures and options
 contracts under its hedging program.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;As of September&amp;#xA0;30,
 2017,&amp;#xA0;September&amp;#xA0;30, 2016 and December&amp;#xA0;31, 2016, the
 Company&amp;#x2019;s derivatives that are not designated as hedging
 instruments under FASB ASC 815-20 have a fair value of $0.1
 million, $0.2 million and $0.4 million, respectively.&lt;/font&gt;&lt;/p&gt;

 The Company is subject to Federal and State income taxes as well as
 various other business taxes. This process involves estimating the
 Company&amp;#x2019;s current tax liabilities as well as assessing
 temporary and permanent differences resulting from the timing of
 the deductions of expenses and recognition of taxable income for
 tax and book accounting purposes. These temporary differences
 result in deferred tax assets and liabilities, which are included
 in the Company&amp;#x2019;s Consolidated Balance Sheets. The Company
 accounts for income tax assets, liabilities and expenses in
 accordance with the Financial Accounting Standards Board (FASB)
 Codification guidance on Income Taxes. The Company classifies
 penalty and interest expense related to income tax liabilities as
 income tax expense and interest expense, respectively, in the
 Consolidated Statements of Earnings.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="margin-top:12px;margin-bottom:0px"&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;Provisions for income taxes
 are calculated in each of the jurisdictions in which the Company
 operates for each period for which a statement of earnings is
 presented. The Company accounts for income taxes in accordance with
 the FASB Codification guidance on Income Taxes, which requires an
 asset and liability approach for the financial accounting and
 reporting of income taxes. Significant judgments and estimates are
 required in determining the current and deferred tax assets and
 liabilities. The Company&amp;#x2019;s current and deferred tax assets
 and liabilities reflect its best assessment of estimated future
 taxes to be paid. In accordance with the FASB Codification, the
 Company periodically assesses the realization of its deferred tax
 assets and liabilities and adjusts the income tax provision, the
 current tax liability and deferred taxes in the period in which the
 facts and circumstances which gave rise to the revision become
 known.&lt;/font&gt;&lt;/p&gt;

 Marketable Securities&lt;/b&gt; &amp;#x2013; In 2015, the Company established
 a trust through which it invests in a variety of equity and fixed

 The cost of additions to Utility Plant and the cost of renewals and
 betterments are capitalized. Cost consists of labor, materials,
 services and certain indirect construction costs, including an
 allowance for funds used during construction (AFUDC). The costs of
 current repairs and minor replacements are charged to appropriate
 operating expense accounts. The original cost of utility plant
 retired or otherwise disposed of is charged to the accumulated
 provision for depreciation. The Company includes in its mass asset
 depreciation rates, which are periodically reviewed as part of its
 ratemaking proceedings, cost of removal amounts to provide for
 future negative salvage value. At September&amp;#xA0;30,
 2017,&amp;#xA0;September&amp;#xA0;30, 2016 and December&amp;#xA0;31, 2016, the
 Company estimates that the cost of removal amounts, which are
 recorded on the Consolidated Balance Sheets in Cost of Removal
 Obligations are $84.8 million, $77.4 million, and $77.0 million,
 respectively.&lt;/font&gt;&lt;/p&gt;

 &amp;#x2013; Unitil Corporation (Unitil or the Company) is a public
 utility holding company. Unitil and its subsidiaries are subject to
 regulation as a holding company system by the Federal Energy
 Regulatory Commission (FERC) under the Energy Policy Act of 2005.
 The following companies are wholly-owned subsidiaries of Unitil:
 Unitil Energy Systems, Inc. (Unitil Energy), Fitchburg Gas and
 Electric Light Company (Fitchburg), Northern Utilities, Inc.
 (Northern Utilities), Granite State Gas Transmission, Inc. (Granite
 State), Unitil Power Corp. (Unitil Power), Unitil Realty Corp.
 (Unitil Realty), Unitil Service Corp. (Unitil Service) and its
 non-regulated business unit Unitil Resources, Inc. (Unitil
 Resources). Usource Inc. and Usource L.L.C. are subsidiaries of
 Unitil Resources.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="margin-top:12px;margin-bottom:0px"&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;The Company&amp;#x2019;s earnings
 are seasonal and are typically higher in the first and fourth
 quarters when customers use natural gas for heating
 purposes.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="margin-top:12px;margin-bottom:0px"&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;Unitil&amp;#x2019;s principal
 business is the local distribution of electricity in the
 southeastern seacoast and state capital regions of New Hampshire
 and the greater Fitchburg area of north central Massachusetts, and
 the local distribution of natural gas in southeastern New
 Hampshire, portions of southern and central Maine and in the
 greater Fitchburg area of north central Massachusetts. Unitil has
 three distribution utility subsidiaries, Unitil Energy, which
 operates in New Hampshire, Fitchburg, which operates in
 Massachusetts and Northern Utilities, which operates in New
 Hampshire and Maine (collectively referred to as the distribution
 utilities).&lt;/font&gt;&lt;/p&gt;
 &lt;p style="margin-top:12px;margin-bottom:0px"&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;Granite State is a natural
 gas transportation pipeline, operating 86 miles of underground gas
 transmission pipeline primarily located in Maine and New Hampshire.
 Granite State provides Northern Utilities with interconnection to
 three major natural gas pipelines and access to domestic natural
 gas supplies in the south and Canadian natural gas supplies in the
 north. Granite State derives its revenues principally from the
 transportation services provided to Northern Utilities and, to a
 lesser extent, third-party marketers.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="margin-top:12px;margin-bottom:0px"&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;A fifth utility subsidiary,
 Unitil Power, formerly functioned as the full requirements
 wholesale power supply provider for Unitil Energy. In connection
 with the implementation of electric industry restructuring in New
 Hampshire, Unitil Power ceased being the wholesale supplier of
 Unitil Energy on May&amp;#xA0;1, 2003 and divested of its long-term
 power supply contracts through the sale of the entitlements to the
 electricity associated with various electric power supply contracts
 it had acquired to serve Unitil Energy&amp;#x2019;s
 customers.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="margin-top:12px;margin-bottom:0px"&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;Unitil also has three other
 wholly-owned subsidiaries: Unitil Service; Unitil Realty; and
 Unitil Resources. Unitil Service provides, at cost, a variety of
 administrative and professional services, including regulatory,
 financial, accounting, human resources, engineering, operations,
 technology, energy management and management services on a
 centralized basis to its affiliated Unitil companies. Unitil Realty
 owns and manages the Company&amp;#x2019;s corporate office in Hampton,
 New Hampshire and leases this facility to Unitil Service under a
 long-term lease arrangement. Unitil Resources is the
 Company&amp;#x2019;s wholly-owned non-regulated subsidiary. Usource,
 Inc. and Usource L.L.C. (collectively, Usource) are wholly-owned
 subsidiaries of Unitil Resources. Usource provides brokering and
 advisory services to large commercial and industrial customers in
 the northeastern United States.&lt;/font&gt;&lt;/p&gt;

 Accounts &amp;#x2013;&lt;/b&gt; The Company recognizes a provision for
 doubtful accounts each month based upon the Company&amp;#x2019;s
 experience in collecting electric and gas utility service accounts
 receivable in prior years. At the end of each month, an analysis of
 the delinquent receivables is performed which takes into account an
 assumption about the cash recovery of delinquent receivables. The
 analysis also calculates the amount of written-off receivables that
 are recoverable through regulatory rate reconciling mechanisms. The
 Company&amp;#x2019;s distribution utilities are authorized by regulators
 to recover the costs of their energy commodity portion of bad debts
 through rate mechanisms. Also, the electric and gas divisions of
 Fitchburg are authorized to recover through rates past due amounts
 associated with hardship accounts that are protected from
 shut-off.&amp;#xA0;Evaluating the adequacy of the Allowance for
 Doubtful Accounts requires judgment about the assumptions used in
 the analysis, including the level of customers enrolling in payment
 plans with the Company. It has been the Company&amp;#x2019;s experience
 that the assumptions it has used in evaluating the adequacy of the
 Allowance for Doubtful Accounts have proven to be reasonably
 accurate.&lt;/font&gt;&lt;/p&gt;

 Pronouncements &amp;#x2013;&lt;/b&gt; In August 2017, the FASB issued
 Accounting Standards Update (ASU) No.&amp;#xA0;2017-12,
 &amp;#x201C;Derivatives and Hedging (Topic 815), to improve the
 financial reporting of hedging relationships to better portray the
 economic results of an entity&amp;#x2019;s risk management activities in
 its financial statements and to make certain targeted improvements
 to simplify the application of the hedge accounting guidance in
 current generally accepted accounting principles in the United
 States of America (GAAP). The amendments are effective for all
 entities for annual periods beginning after December&amp;#xA0;15, 2018,
 including interim periods within those annual periods, and will be
 applied prospectively. Early adoption is permitted. The Company
 adopted this new guidance and it did not have a material impact on
 the Company&amp;#x2019;s Consolidated Financial Statements.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;In May 2017, the FASB
 issued Accounting Standards Update ASU No.&amp;#xA0;2017-09,
 &amp;#x201C;Compensation &amp;#x2013; Stock Compensation (Topic 718) &amp;#x2013;
 Scope of Modification Accounting&amp;#x201D;, to clarify when to account
 for a change to the terms or conditions of a share-based payment
 award as a modification. Under the new standard, modification is
 required only if the fair value, the vesting conditions, or the
 classification of an award as equity or liability changes as a
 result of the change in terms or conditions. The amendments are
 effective for all entities for annual periods beginning after
 December&amp;#xA0;15, 2017, including interim periods within those
 annual periods, and will be applied prospectively. Early adoption
 is permitted. The Company adopted this new guidance and it did not
 have a material impact on the Company&amp;#x2019;s Consolidated
 Financial Statements.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;In March 2017, the FASB
 issued ASU No.&amp;#xA0;2017-07, &amp;#x201C;Compensation &amp;#x2013; Retirement
 Benefits (Topic 715): Improving the Presentation of Net Periodic
 Pension Cost and Net Periodic Postretirement Benefit Cost.&amp;#x201D;
 The ASU amends the existing guidance relating to the presentation
 of net periodic pension cost and net periodic postretirement
 benefit cost. The amendment requires an employer to disaggregate
 the service cost component from the other components of net benefit
 cost and provides explicit guidance on how to present the service
 cost component and other components in the income statement. In
 addition, on a prospective basis, the ASU limits the component of
 net benefit cost eligible to be capitalized to service costs. The
 ASU will be effective for the Company on January&amp;#xA0;1, 2018, with
 early adoption permitted. Although the Company is currently
 evaluating the impact the guidance will have on the Consolidated
 Financial Statements and related disclosures, it is not expected to
 have a material impact to financial results.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;In May 2014, the FASB
 issued ASU No.&amp;#xA0;2014-09, Revenue from Contracts with Customers,
 Topic 606, which amends existing revenue recognition guidance,
 effective January&amp;#xA0;1, 2018. The objective of the new standard
 is to provide a single, comprehensive revenue recognition model for
 all contracts with customers to improve comparability across
 entities, industries, jurisdictions, and capital markets and to
 provide more useful information to users of financial statements
 through improved and expanded disclosure requirements.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The majority of the
 Company&amp;#x2019;s revenue, including energy provided to customers, is
 from tariff offerings that provide natural gas or electricity
 without a defined contractual term. For such arrangements, the
 Company generally expects that the revenue from contracts with
 these customers will continue to be equivalent to the electricity
 or natural gas supplied and billed in that period (including
 unbilled revenues) and the adoption of the new guidance will not
 result in a significant shift in the timing of revenue recognition
 for such sales.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Company intends to use
 the modified retrospective method when adopting the new standard on
 January&amp;#xA0;1, 2018. The Company expects that the impact of the
 new guidance will be immaterial to the Consolidated Financial
 Statements. Upon adoption of ASU 2014-09, the Company plans to
 disclose revenues from contracts with customers separately from
 rate adjustment mechanism revenue.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;In March 2016, the FASB
 issued ASU 2016-09, which provides for improvements to employee
 share-based payment accounting. ASU 2016-09 is effective for fiscal
 years, and interim periods within those years, beginning after
 December&amp;#xA0;15, 2016. ASU 2016-09 simplifies several aspects of
 the accounting for employee share-based payment transactions,
 including the accounting for income taxes, forfeitures, and
 statutory tax withholding requirements, as well as classification
 in the statement of cash flows. The Company adopted this new
 guidance in the first quarter of 2017 and it did not have an impact
 on the Company&amp;#x2019;s Consolidated Financial
 Statements.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 12px"&gt;
 &amp;#xA0;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 0px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;In February 2016, the FASB
 issued ASU 2016-02, Leases, Topic 842, which for lessees requires
 balance sheet recognition of right-of-use assets and lease
 liabilities for most leases.&amp;#xA0;This guidance will be effective
 for interim and annual reporting periods beginning after Dec. 15,
 2018.&amp;#xA0;The Company has not yet fully determined the impacts of
 implementation.&amp;#xA0;However, adoption is expected to occur on Jan.
 1, 2019 utilizing the practical expedients provided by the
 standard.&amp;#xA0;As such, agreements entered into prior to Jan. 1,
 2017 that are currently considered leases are expected to be
 recognized on the consolidated balance sheet, including contracts
 for use of office space and equipment. The Company expects that
 similar agreements entered into after December&amp;#xA0;31, 2016 will
 generally qualify as leases under the new standard, but has not yet
 completed its evaluation of certain other contracts, including
 arrangements for the secondary use of assets, such as land
 easements.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;In January 2016, the FASB
 issued Accounting Standards Update (ASU) 2016-01 which addresses
 certain aspects of recognition, measurement, presentation and
 disclosure of financial instruments. A financial instrument is
 defined as cash, evidence of ownership interest in a company or
 other entity, or a contract that both: (i)&amp;#xA0;imposes on one
 entity a contractual obligation either to deliver cash or another
 financial instrument to a second entity or to exchange other
 financial instruments on potentially unfavorable terms with the
 second entity and (ii)&amp;#xA0;conveys to that second entity a
 contractual right either to receive cash or another financial
 instruments from the first entity or to exchange other financial
 instruments on potentially favorable terms with the first entity.
 This pronouncement is effective for financial statements issued for
 annual periods beginning after December&amp;#xA0;15, 2017 and interim
 periods within those annual periods with earlier application
 permitted as of the beginning of the fiscal year of adoption. The
 Company is evaluating the impact that this new guidance will have
 on the Company&amp;#x2019;s Consolidated Financial
 Statements.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Other than the
 pronouncements discussed above, there are no recently issued
 pronouncements that the Company has not already adopted or that
 have a material impact on the Company.&lt;/font&gt;&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 0px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Exchange Gas Obligation
 &amp;#x2013; Northern Utilities enters into gas exchange agreements
 under which Northern Utilities releases certain natural gas
 pipeline and storage assets, resells the natural gas storage
 inventory to an asset manager and subsequently repurchases the
 inventory over the course of the natural gas heating season at the
 same price at which it sold the natural gas inventory to the asset
 manager. The gas inventory related to these agreements is recorded
 in Exchange Gas Receivable on the Company&amp;#x2019;s Consolidated
 Balance Sheets while the corresponding obligations are recorded in
 Energy Supply Obligations.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Renewable Energy Portfolio
 Standards &amp;#x2013; Renewable Energy Portfolio Standards (RPS)
 require retail electricity suppliers, including public utilities,
 to demonstrate that required percentages of their sales are met
 with power generated from certain types of resources or
 technologies. Compliance is demonstrated by purchasing and retiring
 Renewable Energy Certificates (REC) generated by facilities
 approved by the state as qualifying for REC treatment. Unitil
 Energy and Fitchburg purchase RECs in compliance with RPS
 legislation in New Hampshire and Massachusetts for supply provided
 to default service customers. RPS compliance costs are a supply
 cost that is recovered in customer default service rates. Unitil
 Energy and Fitchburg collect RPS compliance costs from customers
 throughout the year and demonstrate compliance for each calendar
 year on the following July&amp;#xA0;1. Due to timing differences
 between collection of revenue from customers and payment of REC
 costs to suppliers, Unitil Energy and Fitchburg typically maintain
 accrued revenue for RPS compliance which is recorded in Accrued
 Revenue with a corresponding liability in Energy Supply Obligations
 on the Company&amp;#x2019;s Consolidated Balance Sheets.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Fitchburg has entered into
 long-term renewable contracts for electric energy and/or renewable
 energy credits pursuant to Massachusetts legislation, specifically,
 the Act Relative to Green Communities of 2008 and the Act Relative
 to Competitively Priced Electricity (2012)&amp;#xA0;in the
 Commonwealth, and the MDPU&amp;#x2019;s regulations implementing the
 legislation. The generating facilities associated with three of
 these contracts have been constructed and are operating. A recent
 round of long-term renewable energy procurements was conducted
 during 2016 and several contracts were finalized and submitted to
 the MDPU in September, 2017 for approval. Additional procurements
 have been issued in compliance with the Act to Promote Energy
 Diversity (2016). Fitchburg recovers the costs associated with
 long-term renewable contracts on a fully reconciling basis through
 a MDPU-approved cost recovery mechanism.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Power Supply Contract
 Divestitures &amp;#x2013; As a result of the restructuring of the
 utility industry in New Hampshire and Massachusetts, Unitil
 Energy&amp;#x2019;s and Fitchburg&amp;#x2019;s customers have the opportunity
 to purchase their electric or natural gas supplies from third-party
 suppliers. In connection with the implementation of retail choice,
 Unitil Power, which formerly functioned as the wholesale power
 supply provider for Unitil Energy, and Fitchburg divested their
 long-term power supply contracts through the sale of the
 entitlements to the electricity sold under those contracts. Unitil
 Energy and Fitchburg recover in their rates all the costs
 associated with the divestiture of their power supply portfolios
 and have secured regulatory approval from the NHPUC and MDPU,
 respectively, for the recovery of power supply-related stranded
 costs. The obligations related to these divestitures are recorded
 in Energy Supply Obligations on the Company&amp;#x2019;s Consolidated
 Balance Sheets with corresponding regulatory assets recorded in
 Accrued Revenue (current portion) and Regulatory Assets (long-term
 portion).&lt;/font&gt;&lt;/p&gt;

 north. Granite State derives its revenues principally from the
 transportation services provided to Northern Utilities and, to a
 lesser extent, third-party marketers.</font></p>
 <p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"><font style="FONT-FAMILY: Times New Roman" size="2">A fifth utility subsidiary,
 Unitil Power, formerly functioned as the full requirements
 wholesale power supply provider for Unitil Energy. In connection
 with the implementation of electric industry restructuring in New
 Hampshire, Unitil Power ceased being the wholesale supplier of
 Unitil Energy on May&#xA0;1, 2003 and divested of its long-term
 power supply contracts through the sale of the entitlements to the
 electricity associated with various electric power supply contracts
 it had acquired to serve Unitil Energy&#x2019;s
 customers.</font></p>
 <p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"><font style="FONT-FAMILY: Times New Roman" size="2">Unitil also has three other

 Unitil Resources. Unitil Service provides, at cost, a variety of
 administrative and professional services, including regulatory,
 financial, accounting, human resources, engineering, operations,
 technology, energy management and management services on a
 centralized basis to its affiliated Unitil companies. Unitil Realty

 New Hampshire and leases this facility to Unitil Service under a
 long-term lease arrangement. Unitil Resources is the
 Company&#x2019;s wholly-owned non-regulated subsidiary. Usource,

 <p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"><font style="FONT-FAMILY: Times New Roman" size="2"><b>Income Taxes &#x2013;</b>
 The Company is subject to Federal and State income taxes as well as
 various other business taxes. This process involves estimating the
 Company&#x2019;s current tax liabilities as well as assessing
 temporary and permanent differences resulting from the timing of
 the deductions of expenses and recognition of taxable income for
 tax and book accounting purposes. These temporary differences
 result in deferred tax assets and liabilities, which are included
 in the Company&#x2019;s Consolidated Balance Sheets. The Company
 accounts for income tax assets, liabilities and expenses in
 accordance with the Financial Accounting Standards Board (FASB)
 Codification guidance on Income Taxes. The Company classifies
 penalty and interest expense related to income tax liabilities as
 income tax expense and interest expense, respectively, in the
 Consolidated Statements of Earnings.</font></p>
 <p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"><font style="FONT-FAMILY: Times New Roman" size="2">Provisions for income taxes
 are calculated in each of the jurisdictions in which the Company
 operates for each period for which a statement of earnings is
 presented. The Company accounts for income taxes in accordance with
 the FASB Codification guidance on Income Taxes, which requires an
 asset and liability approach for the financial accounting and
 reporting of income taxes. Significant judgments and estimates are
 required in determining the current and deferred tax assets and
 liabilities. The Company&#x2019;s current and deferred tax assets
 and liabilities reflect its best assessment of estimated future
 taxes to be paid. In accordance with the FASB Codification, the
 Company periodically assesses the realization of its deferred tax
 assets and liabilities and adjusts the income tax provision, the
 current tax liability and deferred taxes in the period in which the
 facts and circumstances which gave rise to the revision become
 known.</font></p>
 <p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"><font style="FONT-FAMILY: Times New Roman" size="2"><b>Cash and Cash
 Equivalents &#x2013;</b> Cash and Cash Equivalents include all cash
 and cash equivalents to which the Company has legal title. Cash
 equivalents include short-term investments with original maturities
 of three months or less and interest bearing deposits. The
 Company&#x2019;s cash and cash equivalents are held at financial
 institutions and at times may exceed federally insured limits. The
 Company has not experienced any losses in such accounts. Under the
 Independent System Operator&#x2014;New England (ISO-NE) Financial
 Assurance Policy (Policy), Unitil&#x2019;s subsidiaries Unitil
 Energy, Fitchburg and Unitil Power are required to provide
 assurance of their ability to satisfy their obligations to ISO-NE.
 Under this Policy, Unitil&#x2019;s subsidiaries provide cash
 deposits covering approximately 2-1/2 months of outstanding
 obligations, less credit amounts that are based on the
 Company&#x2019;s credit rating. As of September&#xA0;30,
 2017,&#xA0;September&#xA0;30, 2016 and December&#xA0;31, 2016, the
 Unitil subsidiaries had deposited $4.8 million, $3.5 million and
 $2.8 million, respectively to satisfy their ISO-NE obligations. In
 addition, Northern Utilities has cash margin deposits to satisfy
 requirements for its natural gas hedging program. There were no
 cash margin deposits at Northern Utilities as of September&#xA0;30,
 2017,&#xA0;September&#xA0;30, 2016 and December&#xA0;31,
 2016.</font></p>
 <p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"><font style="FONT-FAMILY: Times New Roman" size="2"><b>Allowance for Doubtful
 Accounts &#x2013;</b> The Company recognizes a provision for
 doubtful accounts each month based upon the Company&#x2019;s
 experience in collecting electric and gas utility service accounts
 receivable in prior years. At the end of each month, an analysis of
 the delinquent receivables is performed which takes into account an
 assumption about the cash recovery of delinquent receivables. The
 analysis also calculates the amount of written-off receivables that
 are recoverable through regulatory rate reconciling mechanisms. The
 Company&#x2019;s distribution utilities are authorized by regulators
 to recover the costs of their energy commodity portion of bad debts
 through rate mechanisms. Also, the electric and gas divisions of
 Fitchburg are authorized to recover through rates past due amounts
 associated with hardship accounts that are protected from
 shut-off.&#xA0;Evaluating the adequacy of the Allowance for
 Doubtful Accounts requires judgment about the assumptions used in
 the analysis, including the level of customers enrolling in payment
 plans with the Company. It has been the Company&#x2019;s experience
 that the assumptions it has used in evaluating the adequacy of the
 Allowance for Doubtful Accounts have proven to be reasonably
 accurate.</font></p>
 <p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"><font style="FONT-FAMILY: Times New Roman" size="2">The Allowance for Doubtful
 Accounts as of September&#xA0;30, 2017,&#xA0;September&#xA0;30,

 Receivable, net on the accompanying unaudited consolidated balance
 sheets, was as follows:</font></p>

 <p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"><font style="FONT-FAMILY: Times New Roman" size="2">Generally, the Company
 receives a return on investment on its regulated assets for which a
 cash outflow has been made. Included in Regulatory Assets as of
 September&#xA0;30, 2017 are $1.4 million of deferred storm charges
 to be recovered over the next year and $7.4 million of
 environmental costs, rate case costs and other expenditures to be
 recovered over varying periods in the next seven years. Regulators
 have authorized recovery of these expenditures, but without a
 return. Regulatory commissions can reach different conclusions
 about the recovery of costs, which can have a material impact on
 the Company&#x2019;s Consolidated Financial Statements. The Company
 believes it is probable that its regulated distribution and
 transmission utilities will recover their investments in long-lived
 assets, including regulatory assets. If the Company, or a portion
 of its assets or operations, were to cease meeting the criteria for
 application of these accounting rules, accounting standards for
 businesses in general would become applicable and immediate
 recognition of any previously deferred costs, or a portion of
 deferred costs, would be required in the year in which the criteria
 are no longer met, if such deferred costs were not recoverable in
 the portion of the business that continues to meet the criteria for
 application of the FASB Codification topic on Regulated Operations.
 If unable to continue to apply the FASB Codification provisions for
 Regulated Operations, the Company would be required to apply the
 provisions for the Discontinuation of Rate-Regulated Accounting
 included in the FASB Codification. In the Company&#x2019;s opinion,
 its regulated operations will be subject to the FASB Codification
 provisions for Regulated Operations for the foreseeable
 future.</font></p>

 The Company&#x2019;s regulated energy subsidiaries enter into energy
 supply contracts to serve their electric and gas customers. The
 Company follows a procedure for determining whether each contract
 qualifies as a derivative instrument under the guidance provided by
 the FASB Codification on Derivatives and Hedging. For each
 contract, the Company reviews and documents the key terms of the
 contract. Based on those terms and any additional relevant
 components of the contract, the Company determines and documents
 whether the contract qualifies as a derivative instrument as
 defined in the FASB Codification. The Company has determined that
 none of its energy supply contracts, other than the regulatory
 approved hedging program, described below, qualifies as a
 derivative instrument under the guidance set forth in the FASB
 Codification.</font></p>
 <p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"><font style="FONT-FAMILY: Times New Roman" size="2">The Company has a
 regulatory approved hedging program for Northern Utilities designed
 to fix or cap a portion of its gas supply costs for the coming
 years of service. Under the program, the Company may purchase call
 option contracts on NYMEX natural gas futures contracts for future
 winter period months.</font></p>
 <p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"><font style="FONT-FAMILY: Times New Roman" size="2">Any gains or losses
 resulting from the change in the fair value of these derivatives
 are passed through to ratepayers directly through Northern
 Utilities&#x2019; Cost of Gas Clause. The fair value of these
 derivatives is determined using Level 2 inputs (valuations based on
 quoted prices in markets that are not active or for which all
 significant inputs are observable, either directly or indirectly),
 specifically based on the NYMEX closing prices for outstanding
 contracts as of the balance sheet date. As a result of the
 ratemaking process, the Company records gains and losses resulting
 from the change in fair value of the derivatives as regulatory
 liabilities or assets, then reclassifies these gains or losses into
 Cost of Gas Sales when the gains and losses are passed through to
 customers through the Cost of Gas Clause.</font></p>

 Standards &#x2013; Renewable Energy Portfolio Standards (RPS)
 require retail electricity suppliers, including public utilities,
 to demonstrate that required percentages of their sales are met
 with power generated from certain types of resources or
 technologies. Compliance is demonstrated by purchasing and retiring
 Renewable Energy Certificates (REC) generated by facilities
 approved by the state as qualifying for REC treatment. Unitil
 Energy and Fitchburg purchase RECs in compliance with RPS
 legislation in New Hampshire and Massachusetts for supply provided
 to default service customers. RPS compliance costs are a supply
 cost that is recovered in customer default service rates. Unitil
 Energy and Fitchburg collect RPS compliance costs from customers
 throughout the year and demonstrate compliance for each calendar
 year on the following July&#xA0;1. Due to timing differences
 between collection of revenue from customers and payment of REC
 costs to suppliers, Unitil Energy and Fitchburg typically maintain
 accrued revenue for RPS compliance which is recorded in Accrued
 Revenue with a corresponding liability in Energy Supply Obligations

 Commonwealth, and the MDPU&#x2019;s regulations implementing the
 legislation. The generating facilities associated with three of
 these contracts have been constructed and are operating. A recent
 round of long-term renewable energy procurements was conducted
 during 2016 and several contracts were finalized and submitted to
 the MDPU in September, 2017 for approval. Additional procurements
 have been issued in compliance with the Act to Promote Energy

 long-term renewable contracts on a fully reconciling basis through
 a MDPU-approved cost recovery mechanism.</font></p>

 Unitil Power, which formerly functioned as the wholesale power

 Pronouncements &#x2013;</b> In August 2017, the FASB issued
 Accounting Standards Update (ASU) No.&#xA0;2017-12,
 &#x201C;Derivatives and Hedging (Topic 815), to improve the
 financial reporting of hedging relationships to better portray the
 economic results of an entity&#x2019;s risk management activities in
 its financial statements and to make certain targeted improvements
 to simplify the application of the hedge accounting guidance in
 current generally accepted accounting principles in the United
 States of America (GAAP). The amendments are effective for all
 entities for annual periods beginning after December&#xA0;15, 2018,
 including interim periods within those annual periods, and will be
 applied prospectively. Early adoption is permitted. The Company
 adopted this new guidance and it did not have a material impact on
 the Company&#x2019;s Consolidated Financial Statements.</font></p>
 <p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"><font style="FONT-FAMILY: Times New Roman" size="2">In May 2017, the FASB
 issued Accounting Standards Update ASU No.&#xA0;2017-09,
 &#x201C;Compensation &#x2013; Stock Compensation (Topic 718) &#x2013;
 Scope of Modification Accounting&#x201D;, to clarify when to account
 for a change to the terms or conditions of a share-based payment
 award as a modification. Under the new standard, modification is
 required only if the fair value, the vesting conditions, or the
 classification of an award as equity or liability changes as a
 result of the change in terms or conditions. The amendments are
 effective for all entities for annual periods beginning after
 December&#xA0;15, 2017, including interim periods within those
 annual periods, and will be applied prospectively. Early adoption
 is permitted. The Company adopted this new guidance and it did not
 have a material impact on the Company&#x2019;s Consolidated
 Financial Statements.</font></p>
 <p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"><font style="FONT-FAMILY: Times New Roman" size="2">In March 2017, the FASB
 issued ASU No.&#xA0;2017-07, &#x201C;Compensation &#x2013; Retirement
 Benefits (Topic 715): Improving the Presentation of Net Periodic
 Pension Cost and Net Periodic Postretirement Benefit Cost.&#x201D;
 The ASU amends the existing guidance relating to the presentation
 of net periodic pension cost and net periodic postretirement
 benefit cost. The amendment requires an employer to disaggregate
 the service cost component from the other components of net benefit
 cost and provides explicit guidance on how to present the service
 cost component and other components in the income statement. In
 addition, on a prospective basis, the ASU limits the component of
 net benefit cost eligible to be capitalized to service costs. The
 ASU will be effective for the Company on January&#xA0;1, 2018, with
 early adoption permitted. Although the Company is currently
 evaluating the impact the guidance will have on the Consolidated
 Financial Statements and related disclosures, it is not expected to
 have a material impact to financial results.</font></p>
 <p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"><font style="FONT-FAMILY: Times New Roman" size="2">In May 2014, the FASB
 issued ASU No.&#xA0;2014-09, Revenue from Contracts with Customers,
 Topic 606, which amends existing revenue recognition guidance,
 effective January&#xA0;1, 2018. The objective of the new standard
 is to provide a single, comprehensive revenue recognition model for
 all contracts with customers to improve comparability across
 entities, industries, jurisdictions, and capital markets and to
 provide more useful information to users of financial statements
 through improved and expanded disclosure requirements.</font></p>
 <p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"><font style="FONT-FAMILY: Times New Roman" size="2">The majority of the
 Company&#x2019;s revenue, including energy provided to customers, is
 from tariff offerings that provide natural gas or electricity
 without a defined contractual term. For such arrangements, the
 Company generally expects that the revenue from contracts with
 these customers will continue to be equivalent to the electricity
 or natural gas supplied and billed in that period (including
 unbilled revenues) and the adoption of the new guidance will not
 result in a significant shift in the timing of revenue recognition
 for such sales.</font></p>
 <p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"><font style="FONT-FAMILY: Times New Roman" size="2">The Company intends to use
 the modified retrospective method when adopting the new standard on
 January&#xA0;1, 2018. The Company expects that the impact of the
 new guidance will be immaterial to the Consolidated Financial
 Statements. Upon adoption of ASU 2014-09, the Company plans to
 disclose revenues from contracts with customers separately from
 rate adjustment mechanism revenue.</font></p>
 <p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"><font style="FONT-FAMILY: Times New Roman" size="2">In March 2016, the FASB
 issued ASU 2016-09, which provides for improvements to employee
 share-based payment accounting. ASU 2016-09 is effective for fiscal
 years, and interim periods within those years, beginning after
 December&#xA0;15, 2016. ASU 2016-09 simplifies several aspects of
 the accounting for employee share-based payment transactions,
 including the accounting for income taxes, forfeitures, and
 statutory tax withholding requirements, as well as classification
 in the statement of cash flows. The Company adopted this new

 balance sheet recognition of right-of-use assets and lease
 liabilities for most leases.&#xA0;This guidance will be effective
 for interim and annual reporting periods beginning after Dec. 15,
 2018.&#xA0;The Company has not yet fully determined the impacts of
 implementation.&#xA0;However, adoption is expected to occur on Jan.
 1, 2019 utilizing the practical expedients provided by the
 standard.&#xA0;As such, agreements entered into prior to Jan. 1,
 2017 that are currently considered leases are expected to be
 recognized on the consolidated balance sheet, including contracts
 for use of office space and equipment. The Company expects that
 similar agreements entered into after December&#xA0;31, 2016 will
 generally qualify as leases under the new standard, but has not yet
 completed its evaluation of certain other contracts, including
 arrangements for the secondary use of assets, such as land
 easements.</font></p>

 Debt</b> &#x2013; Currently, the Company believes that there is no
 active market in the Company&#x2019;s debt securities, which have
 all been sold through private placements. If there were an active
 market for the Company&#x2019;s debt securities, the fair value of
 the Company&#x2019;s long-term debt would be estimated based on the
 quoted market prices for the same or similar issues, or on the
 current rates offered to the Company for debt of the same remaining
 maturities. The fair value of the Company&#x2019;s long-term debt is
 estimated using Level 2 inputs (valuations based on quoted prices
 available in active markets for similar assets or liabilities,
 quoted prices for identical or similar assets or liabilities in
 inactive markets, inputs other than quoted prices that are directly
 observable, and inputs derived principally from market data.) In
 estimating the fair value of the Company&#x2019;s long-term debt,
 the assumed market yield reflects the Moody&#x2019;s Baa Utility
 Bond Average Yield. Costs, including prepayment costs, associated
 with the early settlement of long-term debt are not taken into
 consideration in determining fair value.</font></p>

 of Directors to receive awards under the Stock Plan, including
 awards of restricted shares (Restricted Shares), or of restricted
 stock units (Restricted Stock Units). The Compensation Committee
 has the authority to determine the sizes of awards; determine the
 terms and conditions of awards in a manner consistent with the
 Stock Plan; construe and interpret the Stock Plan and any agreement
 or instrument entered into under the Stock Plan as they apply to
 participants; establish, amend, or waive rules and regulations for
 the Stock Plan&#x2019;s administration as they apply to
 participants; and, subject to the provisions of the Stock Plan,
 amend the terms and conditions of any outstanding award to the
 extent such terms and conditions are within the discretion of the
 Compensation Committee as provided for in the Stock Plan. On
 April&#xA0;19, 2012, the Company&#x2019;s shareholders approved an
 amendment to the Stock Plan to, among other things, increase the
 maximum number of shares of common stock available for awards to
 plan participants.</font></p>

 Committee is authorized to make an equitable adjustment to the
 number and kind of shares of common stock that may be delivered
 under the Stock Plan and, in addition, may authorize and make an
 equitable adjustment to the Stock Plan&#x2019;s annual individual

 require a participant to remit to the Company, an amount sufficient
 to satisfy any taxes required by federal, state, or local law or
 regulation to be withheld with respect to any taxable event arising
 in connection with an Award. For purposes of compensation expense,
 Restricted Shares vest immediately upon a participant becoming

 targeted capital expenditures in 2013 through 2016 as defined under
 the mechanism. The 2017 TIRA, for 2016 expenditures, was approved

 On December&#xA0;22, 2015, the MPUC approved a Targeted Area
 Build-out (TAB) program and associated rate surcharge mechanism.
 This program is designed to allow the economic extension of natural
 gas mains to new, targeted service areas in Maine. It allows
 customers in the targeted area the ability to pay a rate surcharge,
 instead of a large upfront payment or capital contribution to
 connect to the natural gas delivery system. The initial pilot of
 the TAB program was approved for the City of Saco, and is being
 built out over a period of three years, with the potential to add
 1,000 new customers and approximately $1&#xA0;million in annual
 distribution revenue in the Saco area. The second TAB program was
 approved for the Town of Sanford, and has the potential to add
 2,000 new customers and approximately $2 million in annual
 distribution revenue in the Sanford area.</font></p>

 returns for the year ended December&#xA0;31, 2016 with the Internal
 Revenue Service in September 2017 and generated additional federal
 net operating loss (NOL) carryforward assets principally due to
 current tax repair deductions, tax depreciation and research and
 development deductions. As of September&#xA0;30, 2017, the Company
 had recorded cumulative federal and state NOL carryforward assets
 of $23.9&#xA0;million to offset against taxes payable in future
 periods. If unused, the Company&#x2019;s NOL carryforward assets
 will begin to expire in 2029. In addition, at September&#xA0;30,
 2017, the Company had $3.4&#xA0;million of cumulative alternative
 minimum tax credits, general business tax credit and other state
 tax credit carryforwards to offset future income taxes
 payable.</font></p>
 <p style="margin-top:12px;margin-bottom:0px"><font style="font-family:Times New Roman" size="2">The Company evaluated its
 tax positions at September&#xA0;30, 2017 in accordance with the
 FASB Codification, and has concluded that no adjustment for
 recognition, derecognition, settlement and foreseeable future
 events to any tax liabilities or assets as defined by the FASB
 Codification is required. The Company remains subject to
 examination by Federal, Maine, Massachusetts, and New Hampshire tax
 authorities for the tax periods ended December&#xA0;31,
 2014;&#xA0;December&#xA0;31, 2015; and December&#xA0;31, 2016. The
 Company received notice that its Maine income tax return filings
 for the years ended December&#xA0;31, 2014;&#xA0;December&#xA0;31,
 2015; and December&#xA0;31, 2016 are under examination by the Maine
 Revenue Service. Auditor fieldwork is scheduled to occur in the
 fourth quarter of 2017 and the Company does not expect that the
 results of this examination will have a material impact on its
 financial position, operating results or cash flows.</font></p>
 <p style="margin-top:12px;margin-bottom:0px"><font style="font-family:Times New Roman" size="2">The Company bills its
 customers for sales tax in Massachusetts and Maine and consumption
 tax in New Hampshire. These taxes are remitted to the appropriate
 departments of revenue in each state and are excluded from revenues
 on the Company&#x2019;s unaudited Consolidated Statements of
 Earnings.</font></p>

 &#x2013; Unitil Corporation (Unitil or the Company) is a public
 utility holding company. Unitil and its subsidiaries are subject to
 regulation as a holding company system by the Federal Energy
 Regulatory Commission (FERC) under the Energy Policy Act of 2005.
 The following companies are wholly-owned subsidiaries of Unitil:
 Unitil Energy Systems, Inc. (Unitil Energy), Fitchburg Gas and
 Electric Light Company (Fitchburg), Northern Utilities, Inc.
 (Northern Utilities), Granite State Gas Transmission, Inc. (Granite
 State), Unitil Power Corp. (Unitil Power), Unitil Realty Corp.
 (Unitil Realty), Unitil Service Corp. (Unitil Service) and its
 non-regulated business unit Unitil Resources, Inc. (Unitil
 Resources). Usource Inc. and Usource L.L.C. are subsidiaries of
 Unitil Resources.</font></p>
 <p style="margin-top:12px;margin-bottom:0px"><font style="font-family:Times New Roman" size="2">The Company&#x2019;s earnings
 are seasonal and are typically higher in the first and fourth
 quarters when customers use natural gas for heating
 purposes.</font></p>
 <p style="margin-top:12px;margin-bottom:0px"><font style="font-family:Times New Roman" size="2">Unitil&#x2019;s principal
 business is the local distribution of electricity in the
 southeastern seacoast and state capital regions of New Hampshire
 and the greater Fitchburg area of north central Massachusetts, and
 the local distribution of natural gas in southeastern New
 Hampshire, portions of southern and central Maine and in the
 greater Fitchburg area of north central Massachusetts. Unitil has
 three distribution utility subsidiaries, Unitil Energy, which
 operates in New Hampshire, Fitchburg, which operates in
 Massachusetts and Northern Utilities, which operates in New
 Hampshire and Maine (collectively referred to as the distribution
 utilities).</font></p>
 <p style="margin-top:12px;margin-bottom:0px"><font style="font-family:Times New Roman" size="2">Granite State is a natural
 gas transportation pipeline, operating 86 miles of underground gas
 transmission pipeline primarily located in Maine and New Hampshire.
 Granite State provides Northern Utilities with interconnection to
 three major natural gas pipelines and access to domestic natural
 gas supplies in the south and Canadian natural gas supplies in the
 north. Granite State derives its revenues principally from the
 transportation services provided to Northern Utilities and, to a
 lesser extent, third-party marketers.</font></p>
 <p style="margin-top:12px;margin-bottom:0px"><font style="font-family:Times New Roman" size="2">A fifth utility subsidiary,
 Unitil Power, formerly functioned as the full requirements
 wholesale power supply provider for Unitil Energy. In connection
 with the implementation of electric industry restructuring in New
 Hampshire, Unitil Power ceased being the wholesale supplier of
 Unitil Energy on May&#xA0;1, 2003 and divested of its long-term
 power supply contracts through the sale of the entitlements to the
 electricity associated with various electric power supply contracts
 it had acquired to serve Unitil Energy&#x2019;s
 customers.</font></p>
 <p style="margin-top:12px;margin-bottom:0px"><font style="font-family:Times New Roman" size="2">Unitil also has three other
 wholly-owned subsidiaries: Unitil Service; Unitil Realty; and
 Unitil Resources. Unitil Service provides, at cost, a variety of
 administrative and professional services, including regulatory,
 financial, accounting, human resources, engineering, operations,
 technology, energy management and management services on a
 centralized basis to its affiliated Unitil companies. Unitil Realty
 owns and manages the Company&#x2019;s corporate office in Hampton,
 New Hampshire and leases this facility to Unitil Service under a
 long-term lease arrangement. Unitil Resources is the
 Company&#x2019;s wholly-owned non-regulated subsidiary. Usource,
 Inc. and Usource L.L.C. (collectively, Usource) are wholly-owned
 subsidiaries of Unitil Resources. Usource provides brokering and
 advisory services to large commercial and industrial customers in
 the northeastern United States.</font></p>

 The Company is subject to Federal and State income taxes as well as
 various other business taxes. This process involves estimating the
 Company&#x2019;s current tax liabilities as well as assessing
 temporary and permanent differences resulting from the timing of
 the deductions of expenses and recognition of taxable income for
 tax and book accounting purposes. These temporary differences
 result in deferred tax assets and liabilities, which are included
 in the Company&#x2019;s Consolidated Balance Sheets. The Company
 accounts for income tax assets, liabilities and expenses in
 accordance with the Financial Accounting Standards Board (FASB)
 Codification guidance on Income Taxes. The Company classifies
 penalty and interest expense related to income tax liabilities as
 income tax expense and interest expense, respectively, in the
 Consolidated Statements of Earnings.</font></p>
 <p style="margin-top:12px;margin-bottom:0px"><font style="font-family:Times New Roman" size="2">Provisions for income taxes
 are calculated in each of the jurisdictions in which the Company
 operates for each period for which a statement of earnings is
 presented. The Company accounts for income taxes in accordance with
 the FASB Codification guidance on Income Taxes, which requires an
 asset and liability approach for the financial accounting and
 reporting of income taxes. Significant judgments and estimates are
 required in determining the current and deferred tax assets and
 liabilities. The Company&#x2019;s current and deferred tax assets
 and liabilities reflect its best assessment of estimated future
 taxes to be paid. In accordance with the FASB Codification, the
 Company periodically assesses the realization of its deferred tax
 assets and liabilities and adjusts the income tax provision, the
 current tax liability and deferred taxes in the period in which the
 facts and circumstances which gave rise to the revision become
 known.</font></p>

 months or less and interest bearing deposits. The Company&#x2019;s
 cash and cash equivalents are held at financial institutions and at
 times may exceed federally insured limits. The Company has not
 experienced any losses in such accounts. Under the Independent
 System Operator&#x2014;New England (ISO-NE) Financial Assurance
 Policy (Policy), Unitil&#x2019;s subsidiaries Unitil Energy,
 Fitchburg and Unitil Power are required to provide assurance of
 their ability to satisfy their obligations to ISO-NE. Under this
 Policy, Unitil&#x2019;s subsidiaries provide cash deposits covering
 approximately 2-1/2 months of outstanding obligations, less credit

 doubtful accounts each month based upon the Company&#x2019;s
 experience in collecting electric and gas utility service accounts
 receivable in prior years. At the end of each month, an analysis of
 the delinquent receivables is performed which takes into account an
 assumption about the cash recovery of delinquent receivables. The
 analysis also calculates the amount of written-off receivables that
 are recoverable through regulatory rate reconciling mechanisms. The
 Company&#x2019;s distribution utilities are authorized by regulators
 to recover the costs of their energy commodity portion of bad debts
 through rate mechanisms. Also, the electric and gas divisions of
 Fitchburg are authorized to recover through rates past due amounts
 associated with hardship accounts that are protected from
 shut-off.&#xA0;Evaluating the adequacy of the Allowance for
 Doubtful Accounts requires judgment about the assumptions used in
 the analysis, including the level of customers enrolling in payment
 plans with the Company. It has been the Company&#x2019;s experience
 that the assumptions it has used in evaluating the adequacy of the

 The cost of additions to Utility Plant and the cost of renewals and
 betterments are capitalized. Cost consists of labor, materials,
 services and certain indirect construction costs, including an
 allowance for funds used during construction (AFUDC). The costs of
 current repairs and minor replacements are charged to appropriate
 operating expense accounts. The original cost of utility plant
 retired or otherwise disposed of is charged to the accumulated
 provision for depreciation. The Company includes in its mass asset
 depreciation rates, which are periodically reviewed as part of its
 ratemaking proceedings, cost of removal amounts to provide for
 future negative salvage value. At September&#xA0;30,
 2017,&#xA0;September&#xA0;30, 2016 and December&#xA0;31, 2016, the
 Company estimates that the cost of removal amounts, which are
 recorded on the Consolidated Balance Sheets in Cost of Removal
 Obligations are $84.8 million, $77.4 million, and $77.0 million,
 respectively.</font></p>

 receives a return on investment on its regulated assets for which a
 cash outflow has been made. Included in Regulatory Assets as of
 September&#xA0;30, 2017 are $1.4 million of deferred storm charges
 to be recovered over the next year and $7.4 million of
 environmental costs, rate case costs and other expenditures to be
 recovered over varying periods in the next seven years. Regulators
 have authorized recovery of these expenditures, but without a
 return. Regulatory commissions can reach different conclusions
 about the recovery of costs, which can have a material impact on
 the Company&#x2019;s Consolidated Financial Statements. The Company
 believes it is probable that its regulated distribution and
 transmission utilities will recover their investments in long-lived
 assets, including regulatory assets. If the Company, or a portion
 of its assets or operations, were to cease meeting the criteria for
 application of these accounting rules, accounting standards for
 businesses in general would become applicable and immediate
 recognition of any previously deferred costs, or a portion of
 deferred costs, would be required in the year in which the criteria
 are no longer met, if such deferred costs were not recoverable in
 the portion of the business that continues to meet the criteria for
 application of the FASB Codification topic on Regulated Operations.
 If unable to continue to apply the FASB Codification provisions for
 Regulated Operations, the Company would be required to apply the
 provisions for the Discontinuation of Rate-Regulated Accounting
 included in the FASB Codification. In the Company&#x2019;s opinion,
 its regulated operations will be subject to the FASB Codification
 provisions for Regulated Operations for the foreseeable
 future.</font></p>

 The Company&#x2019;s regulated energy subsidiaries enter into energy
 supply contracts to serve their electric and gas customers. The
 Company follows a procedure for determining whether each contract
 qualifies as a derivative instrument under the guidance provided by
 the FASB Codification on Derivatives and Hedging. For each
 contract, the Company reviews and documents the key terms of the
 contract. Based on those terms and any additional relevant
 components of the contract, the Company determines and documents
 whether the contract qualifies as a derivative instrument as
 defined in the FASB Codification. The Company has determined that
 none of its energy supply contracts, other than the regulatory
 approved hedging program, described below, qualifies as a

 <p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"><font style="FONT-FAMILY: Times New Roman" size="2">Renewable Energy Portfolio
 Standards &#x2013; Renewable Energy Portfolio Standards (RPS)
 require retail electricity suppliers, including public utilities,
 to demonstrate that required percentages of their sales are met
 with power generated from certain types of resources or
 technologies. Compliance is demonstrated by purchasing and retiring
 Renewable Energy Certificates (REC) generated by facilities
 approved by the state as qualifying for REC treatment. Unitil
 Energy and Fitchburg purchase RECs in compliance with RPS
 legislation in New Hampshire and Massachusetts for supply provided
 to default service customers. RPS compliance costs are a supply
 cost that is recovered in customer default service rates. Unitil
 Energy and Fitchburg collect RPS compliance costs from customers
 throughout the year and demonstrate compliance for each calendar
 year on the following July&#xA0;1. Due to timing differences
 between collection of revenue from customers and payment of REC
 costs to suppliers, Unitil Energy and Fitchburg typically maintain
 accrued revenue for RPS compliance which is recorded in Accrued
 Revenue with a corresponding liability in Energy Supply Obligations
 on the Company&#x2019;s Consolidated Balance Sheets.</font></p>
 <p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"><font style="FONT-FAMILY: Times New Roman" size="2">Fitchburg has entered into
 long-term renewable contracts for electric energy and/or renewable
 energy credits pursuant to Massachusetts legislation, specifically,
 the Act Relative to Green Communities of 2008 and the Act Relative
 to Competitively Priced Electricity (2012)&#xA0;in the
 Commonwealth, and the MDPU&#x2019;s regulations implementing the
 legislation. The generating facilities associated with three of
 these contracts have been constructed and are operating. A recent
 round of long-term renewable energy procurements was conducted
 during 2016 and several contracts were finalized and submitted to
 the MDPU in September, 2017 for approval. Additional procurements
 have been issued in compliance with the Act to Promote Energy
 Diversity (2016). Fitchburg recovers the costs associated with
 long-term renewable contracts on a fully reconciling basis through
 a MDPU-approved cost recovery mechanism.</font></p>
 <p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"><font style="FONT-FAMILY: Times New Roman" size="2">Power Supply Contract
 Divestitures &#x2013; As a result of the restructuring of the
 utility industry in New Hampshire and Massachusetts, Unitil
 Energy&#x2019;s and Fitchburg&#x2019;s customers have the opportunity
 to purchase their electric or natural gas supplies from third-party
 suppliers. In connection with the implementation of retail choice,
 Unitil Power, which formerly functioned as the wholesale power
 supply provider for Unitil Energy, and Fitchburg divested their
 long-term power supply contracts through the sale of the
 entitlements to the electricity sold under those contracts. Unitil
 Energy and Fitchburg recover in their rates all the costs
 associated with the divestiture of their power supply portfolios
 and have secured regulatory approval from the NHPUC and MDPU,
 respectively, for the recovery of power supply-related stranded
 costs. The obligations related to these divestitures are recorded
 in Energy Supply Obligations on the Company&#x2019;s Consolidated
 Balance Sheets with corresponding regulatory assets recorded in
 Accrued Revenue (current portion) and Regulatory Assets (long-term
 portion).</font></p>

 <p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"><font style="FONT-FAMILY: Times New Roman" size="2"><b>Recently Issued
 Pronouncements &#x2013;</b> In August 2017, the FASB issued
 Accounting Standards Update (ASU) No.&#xA0;2017-12,
 &#x201C;Derivatives and Hedging (Topic 815), to improve the
 financial reporting of hedging relationships to better portray the
 economic results of an entity&#x2019;s risk management activities in
 its financial statements and to make certain targeted improvements
 to simplify the application of the hedge accounting guidance in
 current generally accepted accounting principles in the United
 States of America (GAAP). The amendments are effective for all
 entities for annual periods beginning after December&#xA0;15, 2018,
 including interim periods within those annual periods, and will be
 applied prospectively. Early adoption is permitted. The Company
 adopted this new guidance and it did not have a material impact on
 the Company&#x2019;s Consolidated Financial Statements.</font></p>
 <p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"><font style="FONT-FAMILY: Times New Roman" size="2">In May 2017, the FASB
 issued Accounting Standards Update ASU No.&#xA0;2017-09,
 &#x201C;Compensation &#x2013; Stock Compensation (Topic 718) &#x2013;
 Scope of Modification Accounting&#x201D;, to clarify when to account
 for a change to the terms or conditions of a share-based payment
 award as a modification. Under the new standard, modification is
 required only if the fair value, the vesting conditions, or the
 classification of an award as equity or liability changes as a
 result of the change in terms or conditions. The amendments are
 effective for all entities for annual periods beginning after
 December&#xA0;15, 2017, including interim periods within those
 annual periods, and will be applied prospectively. Early adoption
 is permitted. The Company adopted this new guidance and it did not
 have a material impact on the Company&#x2019;s Consolidated
 Financial Statements.</font></p>
 <p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"><font style="FONT-FAMILY: Times New Roman" size="2">In March 2017, the FASB
 issued ASU No.&#xA0;2017-07, &#x201C;Compensation &#x2013; Retirement
 Benefits (Topic 715): Improving the Presentation of Net Periodic
 Pension Cost and Net Periodic Postretirement Benefit Cost.&#x201D;
 The ASU amends the existing guidance relating to the presentation
 of net periodic pension cost and net periodic postretirement
 benefit cost. The amendment requires an employer to disaggregate
 the service cost component from the other components of net benefit
 cost and provides explicit guidance on how to present the service
 cost component and other components in the income statement. In
 addition, on a prospective basis, the ASU limits the component of
 net benefit cost eligible to be capitalized to service costs. The
 ASU will be effective for the Company on January&#xA0;1, 2018, with
 early adoption permitted. Although the Company is currently
 evaluating the impact the guidance will have on the Consolidated
 Financial Statements and related disclosures, it is not expected to
 have a material impact to financial results.</font></p>
 <p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"><font style="FONT-FAMILY: Times New Roman" size="2">In May 2014, the FASB
 issued ASU No.&#xA0;2014-09, Revenue from Contracts with Customers,
 Topic 606, which amends existing revenue recognition guidance,
 effective January&#xA0;1, 2018. The objective of the new standard
 is to provide a single, comprehensive revenue recognition model for
 all contracts with customers to improve comparability across
 entities, industries, jurisdictions, and capital markets and to
 provide more useful information to users of financial statements
 through improved and expanded disclosure requirements.</font></p>
 <p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"><font style="FONT-FAMILY: Times New Roman" size="2">The majority of the
 Company&#x2019;s revenue, including energy provided to customers, is
 from tariff offerings that provide natural gas or electricity
 without a defined contractual term. For such arrangements, the
 Company generally expects that the revenue from contracts with
 these customers will continue to be equivalent to the electricity
 or natural gas supplied and billed in that period (including
 unbilled revenues) and the adoption of the new guidance will not
 result in a significant shift in the timing of revenue recognition
 for such sales.</font></p>
 <p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"><font style="FONT-FAMILY: Times New Roman" size="2">The Company intends to use
 the modified retrospective method when adopting the new standard on
 January&#xA0;1, 2018. The Company expects that the impact of the
 new guidance will be immaterial to the Consolidated Financial
 Statements. Upon adoption of ASU 2014-09, the Company plans to
 disclose revenues from contracts with customers separately from
 rate adjustment mechanism revenue.</font></p>
 <p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"><font style="FONT-FAMILY: Times New Roman" size="2">In March 2016, the FASB
 issued ASU 2016-09, which provides for improvements to employee
 share-based payment accounting. ASU 2016-09 is effective for fiscal
 years, and interim periods within those years, beginning after
 December&#xA0;15, 2016. ASU 2016-09 simplifies several aspects of
 the accounting for employee share-based payment transactions,
 including the accounting for income taxes, forfeitures, and
 statutory tax withholding requirements, as well as classification
 in the statement of cash flows. The Company adopted this new
 guidance in the first quarter of 2017 and it did not have an impact
 on the Company&#x2019;s Consolidated Financial
 Statements.</font></p>

 <p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 0px"><font style="FONT-FAMILY: Times New Roman" size="2">In February 2016, the FASB
 issued ASU 2016-02, Leases, Topic 842, which for lessees requires
 balance sheet recognition of right-of-use assets and lease
 liabilities for most leases.&#xA0;This guidance will be effective
 for interim and annual reporting periods beginning after Dec. 15,
 2018.&#xA0;The Company has not yet fully determined the impacts of
 implementation.&#xA0;However, adoption is expected to occur on Jan.
 1, 2019 utilizing the practical expedients provided by the
 standard.&#xA0;As such, agreements entered into prior to Jan. 1,
 2017 that are currently considered leases are expected to be
 recognized on the consolidated balance sheet, including contracts
 for use of office space and equipment. The Company expects that
 similar agreements entered into after December&#xA0;31, 2016 will
 generally qualify as leases under the new standard, but has not yet
 completed its evaluation of certain other contracts, including
 arrangements for the secondary use of assets, such as land
 easements.</font></p>
 <p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"><font style="FONT-FAMILY: Times New Roman" size="2">In January 2016, the FASB
 issued Accounting Standards Update (ASU) 2016-01 which addresses
 certain aspects of recognition, measurement, presentation and
 disclosure of financial instruments. A financial instrument is
 defined as cash, evidence of ownership interest in a company or
 other entity, or a contract that both: (i)&#xA0;imposes on one
 entity a contractual obligation either to deliver cash or another
 financial instrument to a second entity or to exchange other
 financial instruments on potentially unfavorable terms with the
 second entity and (ii)&#xA0;conveys to that second entity a
 contractual right either to receive cash or another financial
 instruments from the first entity or to exchange other financial
 instruments on potentially favorable terms with the first entity.
 This pronouncement is effective for financial statements issued for
 annual periods beginning after December&#xA0;15, 2017 and interim
 periods within those annual periods with earlier application
 permitted as of the beginning of the fiscal year of adoption. The
 Company is evaluating the impact that this new guidance will have
 on the Company&#x2019;s Consolidated Financial
 Statements.</font></p>

Such costs are capitalized if they meet both of the following criteria: a. It is probable that future revenue in an amount at least equal to the capitalized cost will result from inclusion of that cost in allowable costs for rate-making purposes. b. Based on available evidence, the future revenue will be provided to permit recovery of the previously incurred cost rather than to provide for expected levels of similar future costs. If the revenue will be provided through an automatic rate-adjustment clause, this criterion requires that the regulator's intent clearly be to permit recovery of the previously incurred cost.</p></div>
