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 previously discussed, 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>

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>

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>

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>

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 March&nbsp;31, 2017,&nbsp;March&nbsp;31, 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> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">On October&nbsp;4, 2013, the Company entered into an Amended and Restated Credit Agreement (as

$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

States of America requires the Company to make estimates and 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 Annual Report on Form 10-K, as filed with the Securities and Exchange Commission on February&nbsp;2, 2017. </FONT></P>

<P STYLE="margin-top:6px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">As discussed above, Unitil meets its external financing needs by issuing short-term and long-term debt. The majority of debt outstanding represents
long-term notes bearing fixed rates of interest. Changes in market interest rates do not affect interest expense resulting from these outstanding long-term debt securities. However, the Company periodically repays its short-term debt borrowings
through the issuance of new long-term debt securities. Changes in market interest rates may affect the interest rate and corresponding interest expense on any new issuances of long-term debt securities. In addition, short-term debt borrowings bear a
variable rate of interest. As a result, changes in short-term interest rates will increase or decrease interest expense in future periods. For example, if the average amount of short-term debt outstanding was $25 million for the period of one year,
a change in interest rates of 1% would result in a change in annual interest expense of approximately $250,000. The average interest rates on the Company&#146;s short-term borrowings and intercompany money pool transactions for the three months
ended March&nbsp;31, 2017 and March&nbsp;31, 2016 were 2.1% and 1.7%, respectively. The average interest rate on the Company&#146;s short-term borrowings for the twelve months ended December&nbsp;31, 2016 was 1.8%. </FONT></P>

Unitil&#146;s three distribution utilities are subject to commodity price risk as part of their traditional operations, the current regulatory framework within which these companies operate allows for full collection of electric power and natural
gas supply costs in rates on a pass-through basis. Consequently, there is limited commodity price risk after consideration of the related rate-making. </FONT></P>

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&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

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. The results of operations for the three months ended March&nbsp;31, 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

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 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

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 March&nbsp;31,
2017,&nbsp;March&nbsp;31, 2016 and December&nbsp;31, 2016, the Unitil subsidiaries had deposited $2.6 million, $2.1 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 March&nbsp;31, 2017,&nbsp;March&nbsp;31, 2016 and December&nbsp;31, 2016. </FONT></P>

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. Evaluating the adequacy of the Allowance

Included in Regulatory Assets as of March&nbsp;31, 2017 are $2.5 million of deferred storm charges to be recovered over the next one and a half years and $8.0 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

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-top:12px;margin-bottom:0px"><FONT

value of these derivatives are passed through to ratepayers directly through Northern Utilities&#146; 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>

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

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

(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 are expected to be finalized and submitted to MDPU for approval in 2017. Additional procurements are expected 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>

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 (current portion) and Other Noncurrent

separate line item or items are not used, the line item or items used in the income statement to present the other components of net benefit cost must be disclosed. The amendments also allow only the service cost component to be eligible for
capitalization when applicable. The amendments are effective for public business entities for annual periods beginning after December&nbsp;15, 2017, including interim periods within those annual periods. The Company is evaluating the impact that
this new guidance will have on the Company&#146;s Consolidated Financial Statements. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">In April and March 2016, the FASB issued ASU 2016-10 and
ASU 2016-08, respectively. ASU 2016-10 clarifies the implementation guidance on licensing and the identification of performance obligations considerations included in ASU 2014-09. ASU 2016-08 provides amendments to clarify the implementation
guidance on principal versus agent considerations included in ASU 2014-09. In August 2015, the FASB issued ASU 2015-14, which defers the effective date of ASU 2014-09. ASU 2014-09 outlines a single comprehensive model for entities to use in
accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The effective date of this pronouncement is for fiscal years beginning after
December&nbsp;15, 2017 with early adoption permitted as of the original effective date. The Company will implement the standard in the first quarter of 2018 on a modified retrospective basis and it is not expected to have a material impact on the
Company&#146;s Consolidated Financial Statements. </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> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">In February 2016, the FASB issued ASU 2016-02, which replaces the

under which a lessee would account for leases as finance (also referred to as capital) leases or operating leases. Both finance leases and operating leases will result in the lessee recognizing a right-of-use asset and corresponding lease liability.
For finance leases the lessee would recognize interest expense and amortization of the right-of-use asset and for operating leases the lessee would recognize straight-line total lease expense. The Company is evaluating the impact that this new
guidance will have on the Company&#146;s Consolidated Financial Statements. </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>

proceeding is to ensure that the electric distribution companies &#147;adopt grid modernization policies and practices.&#148; In June&nbsp;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&#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

of employment occurs, the Participant&#146;s benefits shall not be paid or commence until the first business day after the date that is six months following the Participant&#146;s termination of employment or, if the Participant dies during such six
month period, on the first business day after the date of the Participant&#146;s death. The first payment that can be made shall include the cumulative amount of any amounts that could not be paid during such
<FONT STYLE="white-space:nowrap">six-month</FONT> period. In addition, interest will accrue at the Federal short-term rate determined under Section 1274(d) of the Code (as in effect on the date of the separation from service or, if such date is not
a business day, the first business day prior to such date) on all payments not paid to the Participant prior to the first business day after the sixth month anniversary of termination of employment that otherwise would have been paid during such <FONT
STYLE="white-space:nowrap">six-month</FONT> period had this delay provision not applied to the Participant and shall be paid with the first payment after such <FONT STYLE="white-space:nowrap">six-month</FONT> period. For all purposes under the Plan,
references to termination of employment or words of similar import shall be interpreted to mean &#147;separation from service,&#148; as that term is used in Section 409A, and the Participant&#146;s employment shall in no event be deemed to have
terminated unless and until a separation from service shall have occurred for purposes of Section 409A. </FONT></P>

increase of $1.5 million, or $0.10 per share, compared to the first quarter of 2016. The Company&#146;s earnings in the first quarter of 2017 were driven by higher natural gas and electric sales margins, reflecting: higher distribution rates,

 &lt;font style="FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;" 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;font style="FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;" 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;font style="FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;" 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;font style="FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;" 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;font style="FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;" size="2"&gt;Unitil also

 Realty; and Unitil Resources. Unitil Service provides, at cost, a
 variety of administrative and professional services, including

 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

 &lt;font style="FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;" size="2"&gt;&lt;b&gt;Income
 Taxes &amp;#x2013;&lt;/b&gt;&amp;#xA0;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 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; FONT-SIZE: medium; FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; FONT-WEIGHT: normal; COLOR: rgb(0,0,0); FONT-STYLE: normal; ORPHANS: 2; WIDOWS: 2; MARGIN-TOP: 12px; LETTER-SPACING: normal; TEXT-INDENT: 0px; font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px"&gt;
 &lt;font style="FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;" 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; FONT-SIZE: medium; FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; FONT-WEIGHT: normal; COLOR: rgb(0,0,0); FONT-STYLE: normal; ORPHANS: 2; WIDOWS: 2; MARGIN-TOP: 12px; LETTER-SPACING: normal; TEXT-INDENT: 0px; font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px"&gt;
 &lt;font style="FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;" size="2"&gt;&lt;b&gt;Cash and
 Cash Equivalents &amp;#x2013;&amp;#xA0;&lt;/b&gt;Cash and Cash Equivalents
 includes 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 March&amp;#xA0;31,
 2017,&amp;#xA0;March&amp;#xA0;31, 2016 and December&amp;#xA0;31, 2016, the
 Unitil subsidiaries had deposited $2.6 million, $2.1 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 March&amp;#xA0;31,
 2017,&amp;#xA0;March&amp;#xA0;31, 2016 and December&amp;#xA0;31,
 2016.&lt;/font&gt;&lt;/p&gt;

 &lt;font style="FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;" size="2"&gt;&lt;b&gt;Allowance
 for Doubtful Accounts &amp;#x2013;&lt;/b&gt;&amp;#xA0;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

 Plant &amp;#x2013;&amp;#xA0;&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 March&amp;#xA0;31, 2017,&amp;#xA0;March&amp;#xA0;31, 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 $79.7 million, $72.3
 million, and $77.0 million, respectively.&lt;/font&gt;&lt;/p&gt;

 &lt;font style="FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;" 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 March&amp;#xA0;31, 2017 are $2.5 million of deferred storm
 charges to be recovered over the next one and a half years and $8.0
 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;font style="FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;" size="2"&gt;&lt;b&gt;Derivatives &amp;#x2013;&lt;/b&gt;&amp;#xA0;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;font style="FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;" 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. The Company purchases call option
 contracts on NYMEX natural gas futures contracts for future winter
 period months.&lt;/font&gt;&lt;/p&gt;

 &lt;font style="FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;" 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;font style="FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;" 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;font style="FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;" 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 are
 expected to be finalized and submitted to MDPU for approval in
 2017. Additional procurements are expected 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;

 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 (current

 the Company&amp;#x2019;s Consolidated Balance Sheets with corresponding

 &lt;font style="FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;" size="2"&gt;&lt;b&gt;Recently
 Issued Pronouncements &amp;#x2013;&lt;/b&gt;&amp;#xA0;In March 2017, the FASB issued
 Accounting Standards Update (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 requires an
 employer to report the service cost component in the same line item
 or items as other compensation costs arising from services rendered
 by the pertinent employees during the period. The other components
 of net benefit cost are required to be presented in the income
 statement separately from the service cost component and outside a
 subtotal of income from operations, if one is presented. If a
 separate line item or items are used to present the other
 components of net benefit cost, that line item or items must be
 appropriately described. If a separate line item or items are not
 used, the line item or items used in the income statement to
 present the other components of net benefit cost must be disclosed.
 The amendments also allow only the service cost component to be
 eligible for capitalization when applicable. The amendments are
 effective for public business entities for annual periods beginning
 after December&amp;#xA0;15, 2017, including interim periods within
 those annual periods. 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;font style="FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;" size="2"&gt;In April and
 March 2016, the FASB issued ASU 2016-10 and ASU 2016-08,
 respectively. ASU 2016-10 clarifies the implementation guidance on
 licensing and the identification of performance obligations
 considerations included in ASU 2014-09. ASU 2016-08 provides
 amendments to clarify the implementation guidance on principal
 versus agent considerations included in ASU 2014-09. In August
 2015, the FASB issued ASU 2015-14, which defers the effective date
 of ASU 2014-09. ASU 2014-09 outlines a single comprehensive model
 for entities to use in accounting for revenue arising from
 contracts with customers and supersedes most current revenue
 recognition guidance, including industry-specific guidance. The
 effective date of this pronouncement is for fiscal years beginning
 after December&amp;#xA0;15, 2017 with early adoption permitted as of
 the original effective date. The Company will implement the
 standard in the first quarter of 2018 on a modified retrospective
 basis and it is not expected to have a material impact on the
 Company&amp;#x2019;s Consolidated Financial Statements.&lt;/font&gt;&lt;/p&gt;

 &lt;font style="FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;" 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: medium; FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; FONT-WEIGHT: normal; COLOR: rgb(0,0,0); FONT-STYLE: normal; ORPHANS: 2; WIDOWS: 2; MARGIN-TOP: 12px; LETTER-SPACING: normal; TEXT-INDENT: 0px; font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px"&gt;
 &lt;font style="FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;" size="2"&gt;In February
 2016, the FASB issued ASU 2016-02, which replaces the existing
 guidance in Accounting Standard Codification 840, Leases. ASU
 2016-02 is effective for fiscal years, and interim periods within
 those years, beginning after December&amp;#xA0;15, 2018. ASU 2016-02
 requires a dual approach for lessee accounting under which a lessee
 would account for leases as finance (also referred to as capital)
 leases or operating leases. Both finance leases and operating
 leases will result in the lessee recognizing a right-of-use asset
 and corresponding lease liability. For finance leases the lessee
 would recognize interest expense and amortization of the
 right-of-use asset and for operating leases the lessee would
 recognize straight-line total lease expense. 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;font style="FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;" 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;font style="FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;" size="2"&gt;The Company
 filed its tax returns for the year ended December&amp;#xA0;31, 2015
 with the Internal Revenue Service in September 2016 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 December&amp;#xA0;31,
 2016, 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
 December&amp;#xA0;31, 2016, 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;

 evaluated its tax positions at March&amp;#xA0;31, 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,
 2013;&amp;#xA0;December&amp;#xA0;31, 2014; and December&amp;#xA0;31,

 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;

 &lt;font style="FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;" 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 March&amp;#xA0;31, 2017 are $2.5 million of deferred storm
 charges to be recovered over the next one and a half years and $8.0
 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;font style="FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;" size="2"&gt;&lt;b&gt;Fair Value
 of Long-Term Debt&lt;/b&gt;&amp;#xA0;&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;

 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;font style="FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;" size="2"&gt;The Credit
 Facility contains customary terms and conditions for credit
 facilities of this type, including affirmative and negative
 covenants. There are restrictions on, among other things,
 Unitil&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 or consolidate with another entity or change its line of
 business. The affirmative and negative covenants under the Credit
 Facility shall apply to Unitil 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 Unitil&amp;#x2019;s Funded Debt to Capitalization (as each
 term is defined in the Credit Facility) cannot exceed 65%, tested
 on a quarterly basis. At March&amp;#xA0;31, 2017,&amp;#xA0;March&amp;#xA0;31,

 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
 $3.8 million, $6.7 million and $9.9 million of natural gas storage
 inventory at March&amp;#xA0;31, 2017,&amp;#xA0;March 31, 2016 and
 December&amp;#xA0;31, 2016, respectively, related to these asset
 management agreements. The amount of natural gas inventory released
 in March 2017 and payable in April 2017 is $2.0 million and is
 recorded in Accounts Payable at March&amp;#xA0;31, 2017. The amount of
 natural gas inventory released in March 2016 and payable in April
 2016 was $0.4 million and was recorded in Accounts Payable at
 March&amp;#xA0;31, 2016. The amount of natural gas inventory released
 in December 2016 and payable in January 2017 was $2.1 million and

 &lt;font style="FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;" 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 March&amp;#xA0;31, 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;

 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;

 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;

 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

 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

 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;

 Energy &amp;#x2013; Base Rates &amp;#x2013;&amp;#xA0;&lt;/b&gt;On April&amp;#xA0;29, 2016
 Unitil Energy filed for a $6.3&amp;#xA0;million or 3.6&amp;#xA0;percent
 increase in distribution base rates with the NHPUC. The Company
 also requested a long-term rate plan for the annual recovery in
 future years of the costs associated with utility plant additions.
 The Company was initially provided a temporary increase of $2.4
 million effective July&amp;#xA0;1, 2016, subject to reconciliation with
 the permanent rates when approved by the NHPUC. On April&amp;#xA0;20,
 2017 the NHPUC issued its final order approving a settlement
 between the Company, Commission Staff and the Office of Consumer
 Advocate which provides for a permanent increase of $4.1 million,
 and a three year rate plan with the first rate step adjustment in
 May 2017 of $0.9 million, followed by rate step adjustments in May
 of 2018 and 2019 for 80% of capital expenditures.&lt;/font&gt;&lt;/p&gt;

 MDPU 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. The MDPU also approved a capital cost
 recovery mechanism, providing for annual adjustments to target
 revenues to account for capital spending. In 2016, Fitchburg made
 its first capital cost adjustment filing documenting its capital
 investments for calendar year 2015 which provided approximately
 $0.2 million to $0.3 million of annual revenue. On
 December&amp;#xA0;27, 2016 the MDPU approved this filing subject to
 further investigation and reconciliation. On a prospective basis,
 Fitchburg expects annual revenue adjustments of approximately $0.3
 million.&lt;/font&gt;&lt;/p&gt;

 &amp;#x2013; Gas Operations &amp;#x2013;&amp;#xA0;&lt;/b&gt;On October&amp;#xA0;31, 2016,
 Fitchburg submitted its annual filing under its gas system
 enhancement plan program to recover the estimated cost to be
 incurred in 2017. The filing seeks approval to collect an
 additional $0.9&amp;#xA0;million, over and above the $0.9 million
 already reflected in rates, to recover the cumulative cost of
 investments in the program through the end of 2017. In addition,
 the Company seeks a waiver of the 1.5&amp;#xA0;percent cap on annual
 changes in the revenue requirement eligible for recovery. The
 MDPU&amp;#x2019;s decision on this request is pending and is expected by
 the end of April, 2017, for rates effective May&amp;#xA0;1, 2017. On a
 prospective basis, Fitchburg expects annual revenue adjustments of
 approximately $0.6 million&lt;/font&gt;&lt;/p&gt;

 &amp;#x2013;&amp;#xA0;&lt;/b&gt;The
 settlement in Northern Utilities&amp;#x2019; Maine division&amp;#x2019;s last
 rate case allowed the Company to implement a Targeted
 Infrastructure Replacement Adjustment (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 has an initial term of four years and covers
 targeted capital expenditures in 2013 through 2016. The 2017 TIRA,
 for 2016 expenditures, approved by the MPUC on April 25, 2017,
 provides 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;

 Utilities &amp;#x2013; Targeted Area Build-out Program &amp;#x2013; Maine
 &amp;#x2013;&amp;#xA0;&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 and is being initially piloted
 in the City of Saco. 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 City of Saco TAB program, being built out over a period
 of three years, has the potential to add 1,000 new customers and
 approximately $1&amp;#xA0;million in annual distribution revenue in the
 Saco area. On February&amp;#xA0;28, 2017, the Company filed for
 approval of its second TAB program, for the Town of Sanford, ME.
 The second TAB program has the potential to add 2,000 new customers
 and approximately $2 million in annual distribution revenue in the
 Sanford area. This matter remains pending.&lt;/font&gt;&lt;/p&gt;

 Energy &amp;#x2013; Net Metering &amp;#x2013;&amp;#xA0;&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 legislation requires that a decision on this matter must
 be issued by the NHPUC by March&amp;#xA0;2, 2017. The NHPUC approved an
 extension of the current net metering tariffs on an interim basis
 until it issues its final decision on June&amp;#xA0;2, 2017. Hearings
 on two differing settlement proposals were held the week of
 March&amp;#xA0;27, 2017. This matter remains pending.&lt;/font&gt;&lt;/p&gt;

 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

 &amp;#x2013; Solar Generation &amp;#x2013;&amp;#xA0;&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. The proposal includes a cost
 recovery mechanism that would 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 between 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;

 &amp;#x2013; Energy Diversity &amp;#x2013;&amp;#xA0;&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) 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. On February&amp;#xA0;2, 2017, the
 EDCs filed for approval of the RFP process pursuant to
 Section&amp;#xA0;83d, which was approved by the MDPU on March&amp;#xA0;27,
 2017. On March&amp;#xA0;31, 2017, the EDCs issued the RFP for Long-Term
 Contracts for Clean Energy Projects, pursuant to
 Section&amp;#xA0;83d.&lt;/font&gt;&lt;/p&gt;

 &amp;#x2013; Clean Energy RFP &amp;#x2013;&amp;#xA0;&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 and joint evaluation
 activities are ongoing. Selection of contracts concluded during the
 fourth quarter of 2016 and contract negotiations have been ongoing
 for several proposed projects. Fitchburg&amp;#x2019;s final contracts
 will be subject to review and approval of the MDPU.&lt;/font&gt;&lt;/p&gt;

 &amp;#x2013; Other &amp;#x2013;&amp;#xA0;&lt;/b&gt;On January&amp;#xA0;31, 2017,
 the Massachusetts Department of Energy Resources
 (&amp;#x201C;DOER&amp;#x201D;) presented its final solar incentive program
 design, called Solar Massachusetts Renewable Target
 (&amp;#x201C;SMART&amp;#x201D;) in accordance with Chapter 75 of the Acts of
 2016 which directed the DOER to develop a statewide solar incentive
 program to encourage the continued development of solar renewable
 energy generating sources by residential, commercial, governmental
 and industrial electricity customers throughout the commonwealth.
 The program would replace the state&amp;#x2019;s expiring solar
 incentive program, which uses solar renewable energy credits
 (&amp;#x201C;SRECs&amp;#x201D;) and is known as SREC-2, with a tariff
 program. The tariff would provide for incentive payments which
 would be net of energy value (i.e., total tariff rate minus value
 of energy). The program also includes a variety of tariff adders,
 including incentives for location, such as landfill site, for
 off-takers, such as a community aggregation program, and for other
 technologies, such as behind-the-meter storage. Cost recovery of
 tariff payments and administrative costs may be made through a
 fixed, non-bypassable monthly charge to all distribution customers.
 The DOER&amp;#x2019;s implementation schedule during 2017 includes
 filing emergency regulations, conducting a rulemaking to
 permanently promulgate emergency regulation, MDPU review of model
 tariffs, and final program implementation in January
 2018.&lt;/font&gt;&lt;/p&gt;

 &lt;font style="FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;" 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;font style="FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;" 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;font style="FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;" 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;

 Transmission Formula Rate Proceedings &amp;#x2013;&amp;#xA0;&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. It is not certain at this time whether
 the remand of the decision by the Court will result in the setting
 by FERC of a new ROE at a level higher, lower or equal to the
 existing ROE. 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;

 &lt;font style="FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;" 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. 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
 Court&amp;#x2019;s decision remains subject to a potential motion for
 reconsideration and appeal. The Company believes, based upon
 information furnished by counsel and others, that the ultimate
 resolution of these suits will not have a material impact on its
 financial position, operating results or cash flows.&lt;/font&gt;&lt;/p&gt;

 &amp;#x2013;&lt;/b&gt;&amp;#xA0;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;font style="FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;" 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;font style="FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;" 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;

 January&amp;#xA0;30, 2017, 34,930 Restricted Shares were issued in

 94,880 and 94,706 non-vested shares under the Stock Plan as of
 March&amp;#xA0;31, 2017 and 2016, respectively. The weighted average
 grant date fair value of these shares was $39.55 and $35.24,
 respectively. The compensation expense associated with the issuance
 of shares under the Stock Plan is being recognized over the vesting
 period and was $1.7 million and $1.6 million for the three months
 ended March&amp;#xA0;31, 2017 and 2016, respectively. At March&amp;#xA0;31,
 2017, there was approximately $1.8 million of total unrecognized
 compensation cost under the Stock Plan which is expected to be

 or cancellations under the Stock Plan during the three months ended

 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. The Company purchases 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; 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;As of March&amp;#xA0;31,
 2017,&amp;#xA0;March&amp;#xA0;31, 2016 and December&amp;#xA0;31, 2016 the
 Company had 1.2 billion, 1.8 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 March&amp;#xA0;31, 2017
 and 2016, the Company&amp;#x2019;s derivatives that are not designated
 as hedging instruments under FASB ASC 815-20 have a fair value of
 $0.3 million and less than $0.1 million, respectively.&lt;/font&gt;&lt;/p&gt;

 &lt;font style="FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;" size="2"&gt;&lt;b&gt;Income
 Taxes &amp;#x2013;&lt;/b&gt;&amp;#xA0;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 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;

 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;font style="FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;" size="2"&gt;&lt;b&gt;Allowance
 for Doubtful Accounts &amp;#x2013;&lt;/b&gt;&amp;#xA0;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. Evaluating
 the adequacy of the Allowance for Doubtful Accounts requires
 judgment about the assumptions used in the analysis. 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;

 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

 &lt;font style="FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;" 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;font style="FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;" size="2"&gt;&lt;b&gt;Recently
 Issued Pronouncements &amp;#x2013;&lt;/b&gt;&amp;#xA0;In March 2017, the FASB issued
 Accounting Standards Update (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 requires an
 employer to report the service cost component in the same line item
 or items as other compensation costs arising from services rendered
 by the pertinent employees during the period. The other components
 of net benefit cost are required to be presented in the income
 statement separately from the service cost component and outside a
 subtotal of income from operations, if one is presented. If a
 separate line item or items are used to present the other
 components of net benefit cost, that line item or items must be
 appropriately described. If a separate line item or items are not
 used, the line item or items used in the income statement to
 present the other components of net benefit cost must be disclosed.
 The amendments also allow only the service cost component to be
 eligible for capitalization when applicable. The amendments are
 effective for public business entities for annual periods beginning
 after December&amp;#xA0;15, 2017, including interim periods within
 those annual periods. 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; FONT-SIZE: medium; FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; FONT-WEIGHT: normal; COLOR: rgb(0,0,0); FONT-STYLE: normal; ORPHANS: 2; WIDOWS: 2; MARGIN-TOP: 12px; LETTER-SPACING: normal; TEXT-INDENT: 0px; font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px"&gt;
 &lt;font style="FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;" size="2"&gt;In April and
 March 2016, the FASB issued ASU 2016-10 and ASU 2016-08,
 respectively. ASU 2016-10 clarifies the implementation guidance on
 licensing and the identification of performance obligations
 considerations included in ASU 2014-09. ASU 2016-08 provides
 amendments to clarify the implementation guidance on principal
 versus agent considerations included in ASU 2014-09. In August
 2015, the FASB issued ASU 2015-14, which defers the effective date
 of ASU 2014-09. ASU 2014-09 outlines a single comprehensive model
 for entities to use in accounting for revenue arising from
 contracts with customers and supersedes most current revenue
 recognition guidance, including industry-specific guidance. The
 effective date of this pronouncement is for fiscal years beginning
 after December&amp;#xA0;15, 2017 with early adoption permitted as of
 the original effective date. The Company will implement the
 standard in the first quarter of 2018 on a modified retrospective
 basis and it is not expected to have a material impact on the
 Company&amp;#x2019;s Consolidated Financial Statements.&lt;/font&gt;&lt;/p&gt;

 &lt;font style="FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;" 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: medium; FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; FONT-WEIGHT: normal; COLOR: rgb(0,0,0); FONT-STYLE: normal; ORPHANS: 2; WIDOWS: 2; MARGIN-TOP: 12px; LETTER-SPACING: normal; TEXT-INDENT: 0px; font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px"&gt;
 &lt;font style="FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;" size="2"&gt;In February
 2016, the FASB issued ASU 2016-02, which replaces the existing
 guidance in Accounting Standard Codification 840, Leases. ASU
 2016-02 is effective for fiscal years, and interim periods within
 those years, beginning after December&amp;#xA0;15, 2018. ASU 2016-02
 requires a dual approach for lessee accounting under which a lessee
 would account for leases as finance (also referred to as capital)
 leases or operating leases. Both finance leases and operating
 leases will result in the lessee recognizing a right-of-use asset
 and corresponding lease liability. For finance leases the lessee
 would recognize interest expense and amortization of the
 right-of-use asset and for operating leases the lessee would
 recognize straight-line total lease expense. 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; FONT-SIZE: medium; FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; FONT-WEIGHT: normal; COLOR: rgb(0,0,0); FONT-STYLE: normal; ORPHANS: 2; WIDOWS: 2; MARGIN-TOP: 12px; LETTER-SPACING: normal; TEXT-INDENT: 0px; font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px"&gt;
 &lt;font style="FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;" 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;font style="FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;" size="2"&gt;Other than
 the pronouncements discussed above, there are no recently issued

 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;font style="FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;" 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 are
 expected to be finalized and submitted to MDPU for approval in
 2017. Additional procurements are expected 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;

 Contract Divestitures &amp;#x2013; Unitil Energy&amp;#x2019;s and
 Fitchburg&amp;#x2019;s customers are entitled 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 (current
 portion) and Other Noncurrent Liabilities (noncurrent portion) on
 the Company&amp;#x2019;s Consolidated Balance Sheets with corresponding
 regulatory assets recorded in Accrued Revenue (current portion) and
 Regulatory Assets (noncurrent portion).&lt;/font&gt;&lt;/p&gt;

 <font style="FONT-FAMILY: &quot;Times New Roman&quot;" size="2"><b>Income
 Taxes &#x2013;</b>&#xA0;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 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>

 <font style="FONT-FAMILY: &quot;Times New Roman&quot;" 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>

 <font style="FONT-FAMILY: &quot;Times New Roman&quot;" size="2"><b>Cash and
 Cash Equivalents &#x2013;&#xA0;</b>Cash and Cash Equivalents
 includes 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 March&#xA0;31,
 2017,&#xA0;March&#xA0;31, 2016 and December&#xA0;31, 2016, the
 Unitil subsidiaries had deposited $2.6 million, $2.1 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 March&#xA0;31,
 2017,&#xA0;March&#xA0;31, 2016 and December&#xA0;31,
 2016.</font></p>

 <font style="FONT-FAMILY: &quot;Times New Roman&quot;" size="2"><b>Allowance
 for Doubtful Accounts &#x2013;</b>&#xA0;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. Evaluating
 the adequacy of the Allowance for Doubtful Accounts requires
 judgment about the assumptions used in the analysis. 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>

 <font style="FONT-FAMILY: &quot;Times New Roman&quot;" 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 March&#xA0;31, 2017 are $2.5 million of deferred storm
 charges to be recovered over the next one and a half years and $8.0
 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>

 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>

 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>

 &#x201C;Compensation &#x2013; Retirement Benefits (Topic 715):
 Improving the Presentation of Net Periodic Pension Cost and Net
 Periodic Postretirement Benefit Cost.&#x201D; The ASU requires an
 employer to report the service cost component in the same line item
 or items as other compensation costs arising from services rendered
 by the pertinent employees during the period. The other components
 of net benefit cost are required to be presented in the income
 statement separately from the service cost component and outside a
 subtotal of income from operations, if one is presented. If a
 separate line item or items are used to present the other
 components of net benefit cost, that line item or items must be
 appropriately described. If a separate line item or items are not
 used, the line item or items used in the income statement to
 present the other components of net benefit cost must be disclosed.
 The amendments also allow only the service cost component to be
 eligible for capitalization when applicable. The amendments are
 effective for public business entities for annual periods beginning
 after December&#xA0;15, 2017, including interim periods within
 those annual periods. The Company is evaluating the impact that
 this new guidance will have on the Company&#x2019;s Consolidated
 Financial Statements.</font></p>

 March 2016, the FASB issued ASU 2016-10 and ASU 2016-08,
 respectively. ASU 2016-10 clarifies the implementation guidance on
 licensing and the identification of performance obligations
 considerations included in ASU 2014-09. ASU 2016-08 provides
 amendments to clarify the implementation guidance on principal
 versus agent considerations included in ASU 2014-09. In August
 2015, the FASB issued ASU 2015-14, which defers the effective date
 of ASU 2014-09. ASU 2014-09 outlines a single comprehensive model
 for entities to use in accounting for revenue arising from
 contracts with customers and supersedes most current revenue
 recognition guidance, including industry-specific guidance. The
 effective date of this pronouncement is for fiscal years beginning
 after December&#xA0;15, 2017 with early adoption permitted as of
 the original effective date. The Company will implement the
 standard in the first quarter of 2018 on a modified retrospective
 basis and it is not expected to have a material impact on the
 Company&#x2019;s Consolidated Financial Statements.</font></p>

 2016-02 is effective for fiscal years, and interim periods within
 those years, beginning after December&#xA0;15, 2018. ASU 2016-02
 requires a dual approach for lessee accounting under which a lessee
 would account for leases as finance (also referred to as capital)
 leases or operating leases. Both finance leases and operating
 leases will result in the lessee recognizing a right-of-use asset
 and corresponding lease liability. For finance leases the lessee
 would recognize interest expense and amortization of the
 right-of-use asset and for operating leases the lessee would
 recognize straight-line total lease expense. The Company is
 evaluating the impact that this new guidance will have on the

 <font style="FONT-FAMILY: &quot;Times New Roman&quot;" size="2"><b>Fair Value
 of Long-Term Debt</b>&#xA0;&#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>

 &#x2013;</b>&#xA0;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&#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>

 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&#x2019;s annual individual award limit.</font></p>

 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&#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&#x2019;s death.</font></p>

 Unitil Energy filed for a $6.3&#xA0;million or 3.6&#xA0;percent
 increase in distribution base rates with the NHPUC. The Company
 also requested a long-term rate plan for the annual recovery in
 future years of the costs associated with utility plant additions.
 The Company was initially provided a temporary increase of $2.4
 million effective July&#xA0;1, 2016, subject to reconciliation with
 the permanent rates when approved by the NHPUC. On April&#xA0;20,
 2017 the NHPUC issued its final order approving a settlement
 between the Company, Commission Staff and the Office of Consumer
 Advocate which provides for a permanent increase of $4.1 million,
 and a three year rate plan with the first rate step adjustment in
 May 2017 of $0.9 million, followed by rate step adjustments in May
 of 2018 and 2019 for 80% of capital expenditures.</font></p>

 &#x2013;&#xA0;</b>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 and is being initially piloted
 in the City of Saco. 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 City of Saco TAB program, being built out over a period
 of three years, has the potential to add 1,000 new customers and
 approximately $1&#xA0;million in annual distribution revenue in the
 Saco area. On February&#xA0;28, 2017, the Company filed for
 approval of its second TAB program, for the Town of Sanford, ME.
 The second TAB program has the potential to add 2,000 new customers
 and approximately $2 million in annual distribution revenue in the
 Sanford area. This matter remains pending.</font></p>

 Energy Efficiency Resource Standard Proceeding &#x2013;&#xA0;</b>In May 2015, the NHPUC
 opened a proceeding to establish an Energy Efficiency Resource
 Standard (&#x201C;EERS&#x201D;), an energy efficiency policy with
 specific targets or goals for energy savings that New Hampshire
 electric and gas utilities must meet. On April&#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&#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.</font></p>

 &#x2013; Energy Diversity &#x2013;&#xA0;</b>Governor Baker signed into
 law H4568 &#x201C;An Act to Promote Energy Diversity&#x201D; on
 August&#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&#xA0;83c requires every electric
 distribution company (EDC) to jointly and competitively solicit
 proposals for at least 400 MW&#x2019;s of offshore wind energy
 generation by June&#xA0;30, 2017, as part of a total of 1,600 MW of
 offshore wind the EDCs are directed to procure by June&#xA0;30,
 2027. The procurement requirement is subject to a determination by
 the MDPU that the proposed long-term contracts are cost-effective.
 Section&#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&#xA0;1, 2017,
 for a total of 9,450,000 megawatt-hours by December&#xA0;31, 2022.
 Emergency regulations implementing these new provisions, 220 C.M.R.
 &#xA7; 23.00 et seq. and 220 C.M.R. &#xA7; 24.00 et seq. were
 adopted by the MDPU on December&#xA0;29, 2016, and adopted as final
 regulations on March&#xA0;8, 2017. On February&#xA0;2, 2017, the
 EDCs filed for approval of the RFP process pursuant to
 Section&#xA0;83d, which was approved by the MDPU on March&#xA0;27,
 2017. On March&#xA0;31, 2017, the EDCs issued the RFP for Long-Term
 Contracts for Clean Energy Projects, pursuant to
 Section&#xA0;83d.</font></p>

 the Massachusetts Department of Energy Resources
 (&#x201C;DOER&#x201D;) presented its final solar incentive program
 design, called Solar Massachusetts Renewable Target
 (&#x201C;SMART&#x201D;) in accordance with Chapter 75 of the Acts of
 2016 which directed the DOER to develop a statewide solar incentive
 program to encourage the continued development of solar renewable
 energy generating sources by residential, commercial, governmental
 and industrial electricity customers throughout the commonwealth.
 The program would replace the state&#x2019;s expiring solar
 incentive program, which uses solar renewable energy credits
 (&#x201C;SRECs&#x201D;) and is known as SREC-2, with a tariff
 program. The tariff would provide for incentive payments which
 would be net of energy value (i.e., total tariff rate minus value
 of energy). The program also includes a variety of tariff adders,
 including incentives for location, such as landfill site, for
 off-takers, such as a community aggregation program, and for other
 technologies, such as behind-the-meter storage. Cost recovery of
 tariff payments and administrative costs may be made through a
 fixed, non-bypassable monthly charge to all distribution customers.
 The DOER&#x2019;s implementation schedule during 2017 includes
 filing emergency regulations, conducting a rulemaking to
 permanently promulgate emergency regulation, MDPU review of model
 tariffs, and final program implementation in January
 2018.</font></p>

 <font style="FONT-FAMILY: &quot;Times New Roman&quot;" size="2">In
 December&#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 &#x201C;adopt grid modernization policies and
 practices.&#x201D; In June&#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&#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&#x2019;s three other electric distribution companies
 filed their initial GMPs on August&#xA0;19, 2015. These filings are
 currently under MDPU review and remain pending.</font></p>

 Transmission Formula Rate Proceedings &#x2013;&#xA0;</b>Pursuant to
 Section&#xA0;206 of the Federal Power Act, there are several

 reasonableness of the Return on Equity (&#x201C;ROE&#x201D;)
 component of the ISO-New England, Inc. Participating Transmission
 Owners&#x2019; Regional Network Service and Local Network Service
 formula rates. On April&#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. It is not certain at this time whether
 the remand of the decision by the Court will result in the setting
 by FERC of a new ROE at a level higher, lower or equal to the
 existing ROE. 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

 <font style="FONT-FAMILY: &quot;Times New Roman&quot;" size="2">The
 Company&#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 March&#xA0;31, 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&#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&#x2019;s
 consolidated financial position or results of
 operations.</font></p>

 filed its tax returns for the year ended December&#xA0;31, 2015
 with the Internal Revenue Service in September 2016 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 December&#xA0;31,
 2016, 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
 December&#xA0;31, 2016, 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>

 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,

 for Doubtful Accounts &#x2013;</b>&#xA0;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. Evaluating
 the adequacy of the Allowance for Doubtful Accounts requires
 judgment about the assumptions used in the analysis. 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>

 <font style="FONT-FAMILY: &quot;Times New Roman&quot;" 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 March&#xA0;31, 2017 are $2.5 million of deferred storm
 charges to be recovered over the next one and a half years and $8.0
 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>

 specifically based on the NYMEX closing prices for outstanding

 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>

 Issued Pronouncements &#x2013;</b>&#xA0;In March 2017, the FASB issued

 &#x201C;Compensation &#x2013; Retirement Benefits (Topic 715):
 Improving the Presentation of Net Periodic Pension Cost and Net
 Periodic Postretirement Benefit Cost.&#x201D; The ASU requires an
 employer to report the service cost component in the same line item
 or items as other compensation costs arising from services rendered
 by the pertinent employees during the period. The other components
 of net benefit cost are required to be presented in the income
 statement separately from the service cost component and outside a
 subtotal of income from operations, if one is presented. If a
 separate line item or items are used to present the other
 components of net benefit cost, that line item or items must be
 appropriately described. If a separate line item or items are not
 used, the line item or items used in the income statement to
 present the other components of net benefit cost must be disclosed.
 The amendments also allow only the service cost component to be
 eligible for capitalization when applicable. The amendments are
 effective for public business entities for annual periods beginning
 after December&#xA0;15, 2017, including interim periods within
 those annual periods. The Company is evaluating the impact that
 this new guidance will have on the Company&#x2019;s Consolidated
 Financial Statements.</font></p>

 March 2016, the FASB issued ASU 2016-10 and ASU 2016-08,

 licensing and the identification of performance obligations
 considerations included in ASU 2014-09. ASU 2016-08 provides
 amendments to clarify the implementation guidance on principal
 versus agent considerations included in ASU 2014-09. In August
 2015, the FASB issued ASU 2015-14, which defers the effective date
 of ASU 2014-09. ASU 2014-09 outlines a single comprehensive model
 for entities to use in accounting for revenue arising from
 contracts with customers and supersedes most current revenue
 recognition guidance, including industry-specific guidance. The
 effective date of this pronouncement is for fiscal years beginning
 after December&#xA0;15, 2017 with early adoption permitted as of
 the original effective date. The Company will implement the
 standard in the first quarter of 2018 on a modified retrospective
 basis and it is not expected to have a material impact on the

 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>

 <font style="FONT-FAMILY: &quot;Times New Roman&quot;" size="2">In February
 2016, the FASB issued ASU 2016-02, which replaces the existing
 guidance in Accounting Standard Codification 840, Leases. ASU
 2016-02 is effective for fiscal years, and interim periods within
 those years, beginning after December&#xA0;15, 2018. ASU 2016-02
 requires a dual approach for lessee accounting under which a lessee
 would account for leases as finance (also referred to as capital)
 leases or operating leases. Both finance leases and operating
 leases will result in the lessee recognizing a right-of-use asset
 and corresponding lease liability. For finance leases the lessee
 would recognize interest expense and amortization of the
 right-of-use asset and for operating leases the lessee would
 recognize straight-line total lease expense. The Company is
 evaluating the impact that this new guidance will have on the
 Company&#x2019;s Consolidated Financial Statements.</font></p>

 <font style="FONT-FAMILY: &quot;Times New Roman&quot;" 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>
