 Debt&lt;/b&gt; &amp;#x2013; Currently, the Company believes that there is no
 active market in the Company&amp;#x2019;s debt securities, which have
 all been sold through private placements. If there were an active
 market for the Company&amp;#x2019;s debt securities, the fair value of

 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 0px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;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;

 Arrangements&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 6px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;On October&amp;#xA0;4, 2013,
 the Company entered into an Amended and Restated Credit Agreement
 (the &amp;#x201C;Credit Facility&amp;#x201D;) with a syndicate of lenders
 which amended and restated in its entirety the Company&amp;#x2019;s
 prior credit agreement, dated as of November&amp;#xA0;26, 2008, as
 amended. The Credit Facility extends to October&amp;#xA0;4, 2018 and
 provides for a new 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
 1.375%. Provided there is no event of default under the Credit
 Facility, the Company may on a one-time basis request an increase
 in the aggregate commitments under the Credit Facility by an
 aggregate additional amount of up to $30 million.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;On July&amp;#xA0;24, 2015, the
 Company entered into the First Amendment to the Credit Facility.
 The First Amendment provides for an extension of the scheduled
 termination date to October&amp;#xA0;4, 2020, reduces the daily
 fluctuating rate of interest per annum equal to one-month LIBOR
 plus 1.25%, and reduces other customary credit facility fees. All
 other terms and conditions of the Credit Facility, including
 affirmative and negative covenants, remain substantially
 unchanged.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Company utilizes the
 credit facility for cash management purposes related to its
 short-term operating activities. Total gross borrowings were $55.9
 million and $70.8 million for the quarters ended March&amp;#xA0;31,
 2016 and March&amp;#xA0;31, 2015, respectively. Total gross repayments
 were $50.0 million and $68.1 million for the quarters ended
 March&amp;#xA0;31, 2016 and March&amp;#xA0;31, 2015, respectively. The
 following table details the borrowing limits, amounts outstanding
 and amounts available under the revolving Credit Facility as of
 March&amp;#xA0;31, 2016,&amp;#xA0;March&amp;#xA0;31, 2015 and December&amp;#xA0;31,
 2015:&lt;/font&gt;&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 0px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;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, 2016,&amp;#xA0;March&amp;#xA0;31, 2015
 and December&amp;#xA0;31, 2015, the Company was in compliance with the
 covenants contained in the Credit Facility in effect on that
 date.&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 weighted average
 interest rates on all short-term borrowings were 1.7% and 1.6% for
 the three months ended March&amp;#xA0;31, 2016 and March&amp;#xA0;31, 2015,
 respectively. The weighted average interest rate on all short-term
 borrowings for the twelve months ended December&amp;#xA0;31, 2015 was
 1.5%.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Unitil Corporation and its
 utility subsidiaries, Fitchburg, Unitil Energy, and Northern
 Utilities are currently rated &amp;#x201C;BBB+&amp;#x201D; by
 Standard&amp;#xA0;&amp;amp; Poor&amp;#x2019;s Ratings Services.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;In April 2014, Unitil
 Service Corp. entered into a financing arrangement, structured as a
 capital lease obligation, for various information systems and
 technology equipment. Final funding under this capital lease
 occurred on October&amp;#xA0;30, 2015, resulting in total funding of
 $13.4 million. The capital lease matures on September&amp;#xA0;30,
 2020. As of March&amp;#xA0;31, 2016, there are $2.6 million of current
 and $9.8 million of noncurrent obligations under this capital lease
 on the Company&amp;#x2019;s Consolidated Balance Sheets.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Northern Utilities enters
 into asset management agreements under which Northern Utilities
 releases certain natural gas pipeline and storage assets, resells
 the natural gas storage inventory to an asset manager and
 subsequently repurchases the inventory over the course of the
 natural gas heating season at the same price at which it sold the
 natural gas inventory to the asset manager. There was $6.7 million,
 $5.6 million and $10.8 million of natural gas storage inventory at
 March&amp;#xA0;31, 2016,&amp;#xA0;March 31, 2015 and December&amp;#xA0;31,
 2015, respectively, related to these asset management agreements.
 The amount of natural gas inventory released in March 2016 and
 payable in April 2016 is $0.4 million and is recorded in Accounts
 Payable at March&amp;#xA0;31, 2016. The amount of natural gas inventory
 released in March 2015 and payable in April 2015 was $2.0 million
 and is recorded in Accounts Payable at March&amp;#xA0;31, 2015. The
 amount of natural gas inventory released in December 2015 and
 payable in January 2016 was $0.6 million and was recorded in
 Accounts Payable at December&amp;#xA0;31, 2015.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 18px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;&lt;b&gt;Guarantees&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 6px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Company provides
 limited guarantees on certain energy and natural gas storage
 management contracts entered into by the distribution utilities.
 The Company&amp;#x2019;s policy is to limit the duration of these
 guarantees. As of March&amp;#xA0;31, 2016, there were approximately
 $18.6 million of guarantees outstanding and the longest term
 guarantee extends through August 2016.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Company also guarantees
 the payment of principal, interest and other amounts payable on the
 notes issued by Unitil Realty and Granite State. As of
 March&amp;#xA0;31, 2016, the principal amount outstanding for the 8%
 Unitil Realty notes was $0.9 million, and the principal amount
 outstanding for the 7.15% Granite State notes was $10.0
 million.&lt;/font&gt;&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;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, 2016 are $5.8 million of deferred storm charges to
 be recovered over the next two and a half years and $8.3 million of
 environmental costs, rate case costs and other expenditures to be
 recovered over varying periods in the next seven and a half 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;

 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; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;As of March&amp;#xA0;31,
 2016,&amp;#xA0;March&amp;#xA0;31, 2015 and December&amp;#xA0;31, 2015 the
 Company had 1.8 billion, 2.0 billion and 2.5 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, 2016
 and 2015, the Company&amp;#x2019;s derivatives that are not designated
 as hedging instruments under FASB ASC 815-20 have a fair value of
 less than $0.1 million and $0.1 million, respectively.&lt;/font&gt;&lt;/p&gt;

 Equivalents &amp;#x2013;&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,
 2016,&amp;#xA0;March&amp;#xA0;31, 2015 and December&amp;#xA0;31, 2015, the
 Unitil subsidiaries had deposited $2.1 million, $1.5 million and
 $2.3 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,
 2016,&amp;#xA0;March&amp;#xA0;31, 2015 and December&amp;#xA0;31,

 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;&lt;b&gt;Income Taxes &amp;#x2013;&lt;/b&gt;
 The Company is subject to Federal and State income taxes as well as
 various other business taxes. This process involves estimating the
 Company&amp;#x2019;s current tax liabilities as well as assessing
 temporary and permanent differences resulting from the timing of
 the deductions of expenses and recognition of taxable income for
 tax and book accounting purposes. These temporary differences
 result in deferred tax assets and liabilities, which are included
 in the Company&amp;#x2019;s Consolidated Balance Sheets. The Company
 accounts for income tax assets, liabilities and expenses in
 accordance with the FASB Codification guidance on Income Taxes. The
 Company classifies penalty and interest expense related to income
 tax liabilities as income tax expense and interest expense,
 respectively, in the Consolidated Statements of
 Earnings.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Provisions for income taxes
 are calculated in each of the jurisdictions in which the Company
 operates for each period for which a statement of earnings is
 presented. The Company accounts for income taxes in accordance with
 the FASB Codification guidance on Income Taxes, which requires an
 asset and liability approach for the financial accounting and
 reporting of income taxes. Significant judgments and estimates are
 required in determining the current and deferred tax assets and
 liabilities. The Company&amp;#x2019;s current and deferred tax assets
 and liabilities reflect its best assessment of estimated future
 taxes to be paid. In accordance with the FASB Codification, the
 Company periodically assesses the realization of its deferred tax
 assets and liabilities and adjusts the income tax provision, the
 current tax liability and deferred taxes in the period in which the
 facts and circumstances which gave rise to the revision become
 known.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;In the first quarter of
 2016, the Company adopted ASU 2015-17 which simplifies the
 presentation of deferred income taxes in a classified statement of
 financial position. Current generally accepted accounting
 principles (GAAP) require an entity to separate deferred income tax
 liabilities and assets into current and noncurrent amounts in a
 classified statement of financial position. ASU 2015-17 amends
 current GAAP to require that deferred tax liabilities and assets be
 classified as noncurrent in a classified statement of financial
 position.&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;For all periods presented
 in this Form 10-Q for the quarter ended March&amp;#xA0;31, 2016,
 deferred income taxes are reported as &amp;#x201C;Deferred Income
 Taxes&amp;#x201D; in the &amp;#x201C;Noncurrent Liabilities section on the
 Consolidated Balance Sheets. Prior to adoption, the Company
 reported deferred income taxes in either the &amp;#x201C;Current
 Assets&amp;#x201D; or &amp;#x201C;Current Liabilities&amp;#x201D; and &amp;#x201C;Other
 Noncurrent Assets&amp;#x201D; or &amp;#x201C;Noncurrent Liabilities&amp;#x201D;
 sections on the Consolidated Balance Sheets, depending on whether
 the net current deferred income taxes and net noncurrent deferred
 income taxes were in an asset or liability position, respectively.
 The change in presentation for the quarter ended March&amp;#xA0;31,
 2016 resulted in a reduction of both &amp;#x201C;Current Assets&amp;#x201D;
 and &amp;#x201C;Noncurrent Liabilities&amp;#x201D; for all prior periods
 presented.&lt;/font&gt;&lt;/p&gt;

 Base Rates &amp;#x2013;&lt;/b&gt; On March&amp;#xA0;30, 2016 Unitil Energy filed
 notice of its intent to seek an increase in base rates with the
 NHPUC. NHPUC rules provide that such notice must be filed at least
 30 days prior to the actual filing of a request for an increase in
 rates. The Company will be seeking an increase in base rates of
 approximately $6.0 million, or 4 percent of total revenue. The
 Company intends to request a temporary increase in rates during the
 pendency of the investigation of the permanent rate relief request.
 The Company will also be requesting a long-term rate plan for the
 annual recovery, beginning in 2017, of the costs associated with
 certain plant additions.&lt;/font&gt;&lt;/p&gt;

 filed for a $3.8 million increase in its electric base revenue
 decoupling target, which represents a 5.6 percent increase over
 2014 test year operating electric revenues. The filing included a
 request for approval of a capital cost recovery mechanism to
 recover prudently incurred additions to utility plant on an annual
 basis. Hearings have been completed and briefs have been filed. By
 statute, the MDPU is afforded ten months to act on a request for a
 rate increase. A decision is expected by the end of April,
 2016.&lt;/font&gt;&lt;/p&gt;

 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 2016 TIRA,
 for 2015 expenditures, was filed on February&amp;#xA0;29, 2016, and
 provides for an annual increase in base distribution revenue of
 $1.5 million, effective May&amp;#xA0;1, 2016, and is pending
 approval.&lt;/font&gt;&lt;/p&gt;

 increase in revenue of $1.4 million for investments in gas mains
 extensions and infrastructure replacement projects, effective
 May&amp;#xA0;1, 2014, and a step adjustment that provided for an annual

 FERC issued Opinion No.&amp;#xA0;524-A, the final order in Portland
 Natural Gas Transmission&amp;#x2019;s (PNGTS) Section&amp;#xA0;4 rate case,
 requiring PNGTS to issue refunds to shippers. Northern Utilities
 received a pipeline refund of $22.0 million on April&amp;#xA0;15, 2015.
 As a gas supply-related refund, the entire amount refunded will be
 credited to Northern Utilities&amp;#x2019; customers and marketers. In
 New Hampshire, the refund is being credited to all customers over a
 three year period as directed by the NHPUC. In Maine, the refund
 has been divided into two parts, as directed by the MPUC. Maine
 retail customers who purchase their gas directly from Northern
 Utilities are being credited their portion of the refund over a
 three year period. The second part of the refund was paid on
 October&amp;#xA0;5, 2015 as a one-time lump sum payment directly to
 marketers who transport gas on Northern Utilities&amp;#x2019;
 distribution system. The Company has recorded current and
 noncurrent Regulatory Liabilities of $6.8 million and $3.3 million,
 respectively, on its Consolidated Balance Sheets as of
 March&amp;#xA0;31, 2016.&lt;/font&gt;&lt;/p&gt;

 Fitchburg, the MDPU approved the recovery over three years, without
 carrying charges, of $5.0 million of costs of repair for damage due
 to severe storms, including previously deferred costs incurred in
 2011, as well as costs incurred in 2012 as a result of Superstorm
 Sandy.&lt;/font&gt;&lt;/p&gt;

 Storm Costs &amp;#x2013; On April&amp;#xA0;25, 2013, the NHPUC approved the
 recovery of $2.3 million of costs to repair damage to Unitil
 Energy&amp;#x2019;s electrical system resulting from Superstorm Sandy
 over a five-year period, with carrying charges at the
 Company&amp;#x2019;s long-term cost of debt, net of deferred taxes, or
 4.52%, applied to the uncollected balance through the recovery
 period. Thanksgiving 2014 Snow Storm &amp;#x2013; Unitil Energy has
 requested recovery of $1.7 million for the repair of damage due to
 this storm through its approved storm reserve fund. The request
 remains pending.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="margin-top:12px;margin-bottom:0px"&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;The Company does not believe
 that its storm restoration expenditures and the timing of cost
 recovery will have a material adverse impact on the Company&amp;#x2019;s
 financial condition or results of operations.&lt;/font&gt;&lt;/p&gt;

 Electric Operations &amp;#x2013;&lt;/b&gt; On November&amp;#xA0;17, 2015,
 Fitchburg submitted its 2015 annual reconciliation of costs and
 revenues for transition and transmission under its restructuring
 plan, including the reconciliation of costs and revenues for a
 number of other surcharges and cost factors, for review and
 approval by the MDPU. All of the rates were given final approval by
 the MDPU on December&amp;#xA0;29, 2015, effective January&amp;#xA0;1,
 2016.&lt;/font&gt;&lt;/p&gt;

 Operations &amp;#x2013;&lt;/b&gt; On October&amp;#xA0;31, 2015, Fitchburg
 submitted its second annual filing to recover the estimated costs
 to be incurred in calendar year 2016 under its approved 20 year gas
 system enhancement plan program. The plan was established pursuant
 to a gas leak bill that was signed into law in 2014 that provided
 for the establishment of infrastructure replacement programs to
 address aging natural gas pipeline infrastructure. The Company
 seeks approval to collect in rates $0.9 million for the costs of
 its cumulative capital investments for 2015 and 2016, effective
 May&amp;#xA0;1, 2016. This matter remains pending.&lt;/font&gt;&lt;/p&gt;

 Quality &amp;#x2013;&lt;/b&gt; On March&amp;#xA0;1, 2016, Fitchburg submitted its
 2015 Service Quality Reports for both its gas and electric
 divisions. Fitchburg reported that it met or exceeded its
 benchmarks for service quality performance in all metrics for both
 its gas and electric divisions. On November&amp;#xA0;25, 2015, the MDPU
 approved Fitchburg&amp;#x2019;s 2014 gas division Service Quality Report
 as filed. On March&amp;#xA0;10, 2016, the MDPU approved
 Fitchburg&amp;#x2019;s 2013 electric division Service Quality Report as
 filed. Fitchburg&amp;#x2019;s 2014 electric division and 2015 gas and
 electric division Service Quality Reports remain
 pending.&lt;/font&gt;&lt;/p&gt;

 Guidelines &amp;#x2013;&lt;/b&gt; In December 2015, the MDPU issued its final
 order adopting new and revised Service Quality Guidelines. The
 Company has generally been able to meet or exceed the performance
 metrics of the previous Service Quality Guidelines and believes
 that the new and revised Guidelines will not have a material impact
 on the Company&amp;#x2019;s financial condition or results of
 operations.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="margin-top:12px;margin-bottom:0px"&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;&lt;b&gt;Fitchburg &amp;#x2013; Other
 &amp;#x2013;&lt;/b&gt; 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 filing are
 currently under MDPU review and remain pending.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="margin-top:12px;margin-bottom:0px"&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;On January&amp;#xA0;28, 2016 the
 MDPU approved Fitchburg&amp;#x2019;s Three-Year Energy Efficiency Plan
 for 2016-2018, subject to limited modifications and directives in
 the Order. The Department found that the savings goals included in
 each Three-Year Plan are reasonable and are consistent with the
 achievement of all available cost-effective energy efficiency;
 approved each Program Administrator&amp;#x2019;s program implementation
 cost budget for the Three-Year Plans; approved the performance
 incentive pool, mechanism, and payout rates; found that all
 proposed energy efficiency programs are cost-effective; found that
 funding sources are reasonable and that each Program Administrator
 may recover the funds to implement its energy efficiency plan
 through its EES; and found that each Program Administrator&amp;#x2019;s
 Three-Year Plan is consistent with the Green Communities Act, the
 Guidelines, and Department precedent.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="margin-top:12px;margin-bottom:0px"&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;&lt;b&gt;FERC Transmission Formula
 Rate Proceeding &amp;#x2013;&lt;/b&gt; On December&amp;#xA0;28, 2015, FERC issued
 an order, pursuant to Section&amp;#xA0;206 of the Federal Power Act,
 instituting a proceeding concerning the justness and reasonableness
 of ISO-New England, Inc. Participating Transmission Owners&amp;#x2019;
 Regional Network Service and Local Network Service formula rates
 and to develop formula rate protocols for these rates. Fitchburg
 and Unitil Energy are Participating Transmission Owners, although
 Unitil Energy does not own transmission plant. To the extent that
 this proceeding results in any changes to the rates being charged,
 a refund period will begin as of January&amp;#xA0;4, 2016. The Company
 does not believe this investigation 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;p style="margin-top:18px;margin-bottom:0px"&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;&lt;b&gt;Legal
 Proceedings&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
 &lt;p style="margin-top:6px;margin-bottom:0px"&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;The Company is involved in
 legal and administrative proceedings and claims of various types,
 which arise in the ordinary course of business. The Company
 believes, based upon information furnished by counsel and others,
 that the ultimate resolution of these claims will not have a
 material impact on its financial position, operating results or
 cash flows.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="font-size:1px;margin-top:12px;margin-bottom:0px"&gt;
 &amp;#xA0;&lt;/p&gt;
 &lt;p style="margin-top:0px;margin-bottom:0px"&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;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 Town of Lunenburg has filed a separate action
 in the Court arising out of the December 2008 ice storm. The
 Company continues to believe that both of these suits are without
 merit and will continue to defend itself vigorously. 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;

 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Company&amp;#x2019;s past
 and present operations include activities that are generally
 subject to extensive and complex federal and state environmental
 laws and regulations. The Company believes it is in material
 compliance with applicable environmental and safety laws and
 regulations, and the Company believes that as of March&amp;#xA0;31,
 2016, there were no material losses reasonably likely to be
 incurred in excess of recorded amounts. However, we cannot assure
 you 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.&lt;/font&gt;&lt;/p&gt;

 Manufactured Gas Plant Sites &amp;#x2013;&lt;/b&gt; Northern Utilities has an
 extensive program to identify, investigate and remediate former
 manufactured gas plant (MGP) sites that 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. Northern Utilities has worked with the environmental
 regulatory agencies in both New Hampshire and Maine to address
 environmental concerns with these sites. Northern Utilities or
 others have substantially completed remediation of the Exeter,
 Rochester, Dover, Somersworth, Portsmouth, Lewiston and Scarborough
 sites, though future activities may be required. In Lewiston,
 on-site monitoring continues.&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;Although remediation at the
 site in Exeter has been substantially completed, sediment
 contamination attributed to the former MGP was identified off-site.
 This off-site location has been investigated and associated
 remediation activities were completed in January 2016. The closure
 report, submitted by Northern Utilities in 2016, is currently under
 review by the regulatory agency. At the site in Somersworth, the
 regulatory agency in February 2016 requested that Northern
 Utilities prepare a work plan to investigate an on-site,
 groundwater impact. Northern Utilities submitted the work plan in
 April 2016 and is awaiting regulatory approval to proceed. The site
 in Portland has been investigated and remedial activities have
 largely been completed. Final remediation activities were completed
 in the fourth quarter of 2015, and closure documentation is
 expected to be submitted to the regulatory agency in the second
 quarter of 2016. The State of Maine completed its taking of the
 site via eminent domain for the expansion of the adjacent marine
 terminal in the second quarter of 2014. As a result of this taking,
 and pursuant to an agreement between the State of Maine and
 Northern Utilities, future remedial activities necessitated as a
 result of development of the site will be primarily the
 responsibility of the State of Maine.&lt;/font&gt;&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 0px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The NHPUC and MPUC have
 approved regulatory mechanisms for the recovery of MGP
 environmental costs. For Northern Utilities&amp;#x2019; New Hampshire
 division, the NHPUC has approved the recovery of MGP environmental
 costs over succeeding seven-year periods, without carrying costs.
 For Northern Utilities&amp;#x2019; Maine division, the MPUC has
 authorized the recovery of environmental remediation costs over
 succeeding five-year periods, without carrying costs.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Environmental
 Obligations table below shows the amounts accrued for Northern
 Utilities related to estimated future cleanup costs associated with
 Northern Utilities&amp;#x2019; environmental remediation obligations for
 former MGP sites. Corresponding Regulatory Assets were recorded to
 reflect that the future recovery of these environmental remediation
 costs is expected based on regulatory precedent and established
 practices.&lt;/font&gt;&lt;/p&gt;

 Manufactured Gas Plant Site &amp;#x2013;&lt;/b&gt; Fitchburg completed the
 scheduled site work at the former MGP site at Sawyer Passway,
 located in Fitchburg, Massachusetts in the fourth quarter of 2014.
 The closure documentation for the site was submitted in the fourth
 quarter of 2015 and is under review by the Massachusetts Department
 of Environmental Protection.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Environmental
 Obligations table below shows the amounts accrued for Fitchburg
 related to estimated future cleanup costs for permanent remediation
 of the Sawyer Passway site with a corresponding Regulatory Asset
 recorded to reflect that the recovery of these environmental
 remediation costs are probable through the regulatory process. The
 amounts recorded do not assume any amounts are recoverable from
 insurance companies or other third parties. Fitchburg recovers the
 environmental response costs incurred at this former MGP site in
 gas rates pursuant to the terms of a cost recovery agreement
 approved by the MDPU. Pursuant to this agreement, Fitchburg is
 authorized to amortize and recover environmental response costs
 from gas customers over succeeding seven-year periods, without
 carrying costs.&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&amp;#x2019;s
 ultimate liability for future environmental remediation costs,
 including MGP site costs, may vary from estimates, which may be
 adjusted as new information or future developments become
 available. Based on the Company&amp;#x2019;s current assessment of its
 environmental responsibilities, existing legal requirements and
 regulatory policies, the Company does not believe that these
 environmental costs will have a material adverse effect on the
 Company&amp;#x2019;s consolidated financial position or results of
 operations.&lt;/font&gt;&lt;/p&gt;

 &lt;p style="margin-top:6px;margin-bottom:0px"&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;The Company filed its tax
 returns for the year ended December&amp;#xA0;31, 2014 with the Internal
 Revenue Service (IRS) in September 2015. As of December&amp;#xA0;31,
 2015, the Company had recorded cumulative federal NOL carryforward
 assets and Research and Development (R&amp;amp;D) credit carryforwards
 of $11.3 million to offset against taxes payable in future periods.
 If unused, the Company&amp;#x2019;s federal NOL carryforward assets will
 begin to expire in 2029, and the federal R&amp;amp;D credits will begin
 to expire in 2035. In addition, at December&amp;#xA0;31, 2015, the
 Company had $2.1 million of cumulative Alternative Minimum Tax
 (AMT) credit carryforwards to offset future AMT taxes payable
 indefinitely.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="margin-top:12px;margin-bottom:0px"&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;In 2015, the Company
 recognized research and development tax credits under the rules of
 Section&amp;#xA0;41 of the Internal Revenue Code. The Company will
 continue to recognize a tax benefit on its incremental qualified
 research expenses.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="margin-top:12px;margin-bottom:0px"&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;The Company evaluated its
 tax positions at March&amp;#xA0;31, 2016 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, 2012;&amp;#xA0;December&amp;#xA0;31, 2013;
 and December&amp;#xA0;31, 2014.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="margin-top:12px;margin-bottom:0px"&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;The Company bills its
 customers for sales tax in Massachusetts and Maine and consumption
 tax in New Hampshire. These taxes are remitted to the appropriate
 departments of revenue in each state and are excluded from revenues
 on the Company&amp;#x2019;s unaudited Consolidated Statements of
 Earnings.&lt;/font&gt;&lt;/p&gt;

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

 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 0px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;&lt;b&gt;Basis of Presentation
 &amp;#x2013;&lt;/b&gt; The accompanying unaudited consolidated financial
 statements of Unitil have been prepared in accordance with the
 instructions to Form 10-Q and include all of the information and
 footnotes required by generally accepted accounting principles. In
 the opinion of management, all adjustments considered necessary for
 a fair presentation have been included. The results of operations
 for the three months ended March&amp;#xA0;31, 2016 are not necessarily
 indicative of results to be expected for the year ending
 December&amp;#xA0;31, 2016. For further information, please refer to
 Note 1 of Part II to the Consolidated Financial Statements &amp;#x2013;
 &amp;#x201C;Summary of Significant Accounting Policies&amp;#x201D; of the
 Company&amp;#x2019;s Form 10-K for the year ended December&amp;#xA0;31,
 2015, as filed with the Securities and Exchange Commission (SEC) on
 January&amp;#xA0;28, 2016, for a description of the Company&amp;#x2019;s
 Basis of Presentation. Certain reclassifications of prior year data
 were made in the accompanying financial statements. These
 reclassifications were made to conform to the current year
 presentation.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;&lt;b&gt;Income Taxes &amp;#x2013;&lt;/b&gt;
 The Company is subject to Federal and State income taxes as well as
 various other business taxes. This process involves estimating the
 Company&amp;#x2019;s current tax liabilities as well as assessing
 temporary and permanent differences resulting from the timing of
 the deductions of expenses and recognition of taxable income for
 tax and book accounting purposes. These temporary differences
 result in deferred tax assets and liabilities, which are included
 in the Company&amp;#x2019;s Consolidated Balance Sheets. The Company
 accounts for income tax assets, liabilities and expenses in
 accordance with the FASB Codification guidance on Income Taxes. The
 Company classifies penalty and interest expense related to income
 tax liabilities as income tax expense and interest expense,
 respectively, in the Consolidated Statements of
 Earnings.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Provisions for income taxes
 are calculated in each of the jurisdictions in which the Company
 operates for each period for which a statement of earnings is
 presented. The Company accounts for income taxes in accordance with
 the FASB Codification guidance on Income Taxes, which requires an
 asset and liability approach for the financial accounting and
 reporting of income taxes. Significant judgments and estimates are
 required in determining the current and deferred tax assets and
 liabilities. The Company&amp;#x2019;s current and deferred tax assets
 and liabilities reflect its best assessment of estimated future
 taxes to be paid. In accordance with the FASB Codification, the
 Company periodically assesses the realization of its deferred tax
 assets and liabilities and adjusts the income tax provision, the
 current tax liability and deferred taxes in the period in which the
 facts and circumstances which gave rise to the revision become
 known.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;In the first quarter of
 2016, the Company adopted ASU 2015-17 which simplifies the
 presentation of deferred income taxes in a classified statement of
 financial position. Current generally accepted accounting
 principles (GAAP) require an entity to separate deferred income tax
 liabilities and assets into current and noncurrent amounts in a
 classified statement of financial position. ASU 2015-17 amends
 current GAAP to require that deferred tax liabilities and assets be
 classified as noncurrent in a classified statement of financial
 position.&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;For all periods presented
 in this Form 10-Q for the quarter ended March&amp;#xA0;31, 2016,
 deferred income taxes are reported as &amp;#x201C;Deferred Income
 Taxes&amp;#x201D; in the &amp;#x201C;Noncurrent Liabilities section on the
 Consolidated Balance Sheets. Prior to adoption, the Company
 reported deferred income taxes in either the &amp;#x201C;Current
 Assets&amp;#x201D; or &amp;#x201C;Current Liabilities&amp;#x201D; and &amp;#x201C;Other
 Noncurrent Assets&amp;#x201D; or &amp;#x201C;Noncurrent Liabilities&amp;#x201D;
 sections on the Consolidated Balance Sheets, depending on whether
 the net current deferred income taxes and net noncurrent deferred
 income taxes were in an asset or liability position, respectively.
 The change in presentation for the quarter ended March&amp;#xA0;31,
 2016 resulted in a reduction of both &amp;#x201C;Current Assets&amp;#x201D;
 and &amp;#x201C;Noncurrent Liabilities&amp;#x201D; for all prior periods
 presented.&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;&lt;b&gt;Cash and Cash
 Equivalents &amp;#x2013;&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,
 2016,&amp;#xA0;March&amp;#xA0;31, 2015 and December&amp;#xA0;31, 2015, the
 Unitil subsidiaries had deposited $2.1 million, $1.5 million and
 $2.3 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,
 2016,&amp;#xA0;March&amp;#xA0;31, 2015 and December&amp;#xA0;31,
 2015.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;&lt;b&gt;Allowance for Doubtful
 Accounts &amp;#x2013;&lt;/b&gt; The Company recognizes a provision for
 doubtful accounts each month based upon the Company&amp;#x2019;s
 experience in collecting electric and gas utility service accounts
 receivable in prior years. At the end of each month, an analysis of
 the delinquent receivables is performed which takes into account an
 assumption about the cash recovery of delinquent receivables. The
 analysis also calculates the amount of written-off receivables that
 are recoverable through regulatory rate reconciling mechanisms. The
 Company&amp;#x2019;s distribution utilities are authorized by regulators
 to recover the costs of their energy commodity portion of bad debts
 through rate mechanisms. Also, the electric division of Fitchburg
 is authorized to recover through rates past due amounts associated
 with hardship accounts that are protected from
 shut-off.&amp;#xA0;Evaluating the adequacy of the Allowance for
 Doubtful Accounts requires judgment about the assumptions used in
 the analysis, including the level of customers enrolling in payment
 plans with the Company. It has been the Company&amp;#x2019;s experience
 that the assumptions it has used in evaluating the adequacy of the
 Allowance for Doubtful Accounts have proven to be reasonably
 accurate.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Allowance for Doubtful
 Accounts as of March&amp;#xA0;31, 2016,&amp;#xA0;March&amp;#xA0;31, 2015 and
 December&amp;#xA0;31, 2015, which are included in Accounts Receivable,
 net on the accompanying unaudited consolidated balance sheets, was

 &amp;#x2013;&lt;/b&gt; The cost of additions to Utility Plant and the cost of
 renewals and betterments are capitalized. Cost consists of labor,
 materials, services and certain indirect construction costs,
 including an allowance for funds used during construction (AFUDC).
 The costs of current repairs and minor replacements are charged to
 appropriate operating expense accounts. The original cost of
 utility plant retired or otherwise disposed of is charged to the
 accumulated provision for depreciation. The Company includes in its
 mass asset depreciation rates, which are periodically reviewed as
 part of its ratemaking proceedings, cost of removal amounts to
 provide for future negative salvage value. At March&amp;#xA0;31,
 2016,&amp;#xA0;March&amp;#xA0;31, 2015 and December&amp;#xA0;31, 2015, the
 Company estimates that the cost of removal amounts, which are
 recorded on the Consolidated Balance Sheets in Cost of Removal
 Obligations are $72.3 million, $65.7 million, and $70.1 million,
 respectively.&lt;/font&gt;&lt;/p&gt;

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

 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Generally, the Company
 receives a return on investment on its regulated assets for which a
 cash outflow has been made. Included in Regulatory Assets as of
 March&amp;#xA0;31, 2016 are $5.8 million of deferred storm charges to
 be recovered over the next two and a half years and $8.3 million of
 environmental costs, rate case costs and other expenditures to be
 recovered over varying periods in the next seven and a half years.
 Regulators have authorized recovery of these expenditures, but
 without a return. Regulatory commissions can reach different
 conclusions about the recovery of costs, which can have a material
 impact on the Company&amp;#x2019;s Consolidated Financial Statements.
 The Company believes it is probable that its regulated distribution
 and transmission utilities will recover their investments in
 long-lived assets, including regulatory assets. If the Company, or
 a portion of its assets or operations, were to cease meeting the
 criteria for application of these accounting rules, accounting
 standards for businesses in general would become applicable and
 immediate recognition of any previously deferred costs, or a
 portion of deferred costs, would be required in the year in which
 the criteria are no longer met, if such deferred costs were not
 recoverable in the portion of the business that continues to meet
 the criteria for application of the FASB Codification topic on
 Regulated Operations. If unable to continue to apply the FASB
 Codification provisions for Regulated Operations, the Company would
 be required to apply the provisions for the Discontinuation of
 Rate-Regulated Accounting included in the FASB Codification. In the
 Company&amp;#x2019;s opinion, its regulated operations will be subject
 to the FASB Codification provisions for Regulated Operations for
 the foreseeable future.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 12px"&gt;

 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 0px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;&lt;b&gt;Derivatives &amp;#x2013;&lt;/b&gt;
 The Company&amp;#x2019;s regulated energy subsidiaries enter into energy
 supply contracts to serve their electric and gas customers. The
 Company follows a procedure for determining whether each contract
 qualifies as a derivative instrument under the guidance provided by
 the FASB Codification on Derivatives and Hedging. For each
 contract, the Company reviews and documents the key terms of the
 contract. Based on those terms and any additional relevant
 components of the contract, the Company determines and documents
 whether the contract qualifies as a derivative instrument as
 defined in the FASB Codification. The Company has determined that
 none of its energy supply contracts, other than the regulatory
 approved hedging program, described below, qualifies as a
 derivative instrument under the guidance set forth in the FASB
 Codification.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Company has a
 regulatory approved hedging program for Northern Utilities designed
 to fix or cap a portion of its gas supply costs for the coming
 years of service. 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; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;As of March&amp;#xA0;31,
 2016,&amp;#xA0;March&amp;#xA0;31, 2015 and December&amp;#xA0;31, 2015 the
 Company had 1.8 billion, 2.0 billion and 2.5 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, 2016
 and 2015, the Company&amp;#x2019;s derivatives that are not designated
 as hedging instruments under FASB ASC 815-20 have a fair value of
 less than $0.1 million and $0.1 million, respectively.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;&lt;b&gt;Investments in
 Marketable Securities&lt;/b&gt; &amp;#x2013; In 2015, the Company established
 a trust through which it invests in a variety of equity and fixed
 income mutual funds. These funds are intended to satisfy
 obligations under the Company&amp;#x2019;s Supplemental Executive
 Retirement Plan (&amp;#x201C;SERP&amp;#x201D;) (See further discussion of the
 SERP in Note 9.&lt;/font&gt;&lt;/p&gt;

 2016,&amp;#xA0;March&amp;#xA0;31, 2015 and December&amp;#xA0;31, 2015, the fair
 value of the Company&amp;#x2019;s investments in these trading
 securities, which are recorded on the Consolidated Balance Sheets

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

 Energy Supply Obligations.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Renewable Energy Portfolio
 Standards &amp;#x2013; Renewable Energy Portfolio Standards (RPS)
 require retail electricity suppliers, including public utilities,
 to demonstrate that required percentages of their sales are met
 with power generated from certain types of resources or
 technologies. Compliance is demonstrated by purchasing and retiring
 Renewable Energy Certificates (REC) generated by facilities
 approved by the state as qualifying for REC treatment. Unitil
 Energy and Fitchburg purchase RECs in compliance with RPS
 legislation in New Hampshire and Massachusetts for supply provided
 to default service customers. RPS compliance costs are a supply
 cost that is recovered in customer default service rates. Unitil
 Energy and Fitchburg collect RPS compliance costs from customers
 throughout the year and demonstrate compliance for each calendar
 year on the following July&amp;#xA0;1. Due to timing differences
 between collection of revenue from customers and payment of REC
 costs to suppliers, Unitil Energy and Fitchburg typically maintain
 accrued revenue for RPS compliance which is recorded in Accrued
 Revenue with a corresponding liability in Energy Supply Obligations
 on the Company&amp;#x2019;s Consolidated Balance Sheets.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Fitchburg has entered into
 long-term renewable contracts for electric energy and/or renewable
 energy credits. The generating facilities associated with two of
 these contracts have been constructed and are operating. Another
 contract has been approved by the MDPU and is pending facility
 construction and operation, which is anticipated to begin by the
 end of 2016. Fitchburg will recover its costs under this contract
 through a regulatory approved cost tracker rate
 mechanism.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Power Supply Contract
 Divestitures &amp;#x2013; As a result of the restructuring of the
 utility industry in New Hampshire and Massachusetts, Unitil
 Energy&amp;#x2019;s and Fitchburg&amp;#x2019;s customers have the opportunity
 to purchase their electric or natural gas supplies from third-party
 suppliers. In connection with the implementation of retail choice,
 Unitil Power, which formerly functioned as the wholesale power
 supply provider for Unitil Energy, and Fitchburg divested their
 long-term power supply contracts through the sale of the
 entitlements to the electricity sold under those contracts. Unitil
 Energy and Fitchburg recover in their rates all the costs
 associated with the divestiture of their power supply portfolios
 and have secured regulatory approval from the NHPUC and MDPU,
 respectively, for the recovery of power supply-related stranded
 costs. The obligations related to these divestitures are recorded
 in Energy Supply Obligations on the Company&amp;#x2019;s Consolidated
 Balance Sheets with corresponding regulatory assets recorded in
 Accrued Revenue (current portion) and Regulatory Assets (long-term
 portion).&lt;/font&gt;&lt;/p&gt;

 Communities Act, discussed below in Note 6, Regulatory Matters,
 Fitchburg has entered into long-term renewable contracts for
 electric energy and/or renewable energy credits. The facility
 associated with two of these contracts has been constructed and is
 operating. The other contracts are pending approval by the MDPU as
 well as subsequent facility construction and operation. These
 facilities are anticipated to begin operation by the end of 2016.
 Fitchburg will recover its costs associated with long-term
 renewable contracts on a fully reconciling basis through a

 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;&lt;b&gt;Debt Issuance Costs
 &amp;#x2013;&lt;/b&gt; In the first quarter of 2016, the Company adopted
 Accounting Standards Update (ASU) 2015-03, which requires entities
 to present debt issuance costs related to a debt liability as a
 direct deduction from the carrying amount of that debt liability on
 the balance sheet as opposed to being presented as a deferred
 charge, and ASU 2015-15, which adds paragraphs to ASU 2015-03
 indicating that the SEC staff would not object to an entity
 deferring and presenting debt issuance costs related to
 line-of-credit arrangements as an asset and subsequently amortizing
 the deferred debt issuance costs ratably over the term of the
 line-of-credit arrangement, regardless of whether there are any
 outstanding borrowings on the line-of-credit
 arrangement.&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;For all periods presented
 in this Form 10-Q for the quarter ended March&amp;#xA0;31, 2016,
 unamortized debt issuance costs related to the Company&amp;#x2019;s
 long-term debt are reported on the Consolidated Balance Sheets as a
 reduction of the carrying value of the related debt. Prior to
 adoption, the Company reported the unamortized debt issuance costs
 in &amp;#x201C;Other Assets&amp;#x201D; on the Consolidated Balance Sheets.
 The change in presentation resulted in a reduction of &amp;#x201C;Other
 Assets&amp;#x201D; and &amp;#x201C;Long-Term Debt&amp;#x201D; of $3.1 million and
 $2.9 million as of March&amp;#xA0;31, 2015 and December&amp;#xA0;31, 2015,
 respectively.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;&lt;b&gt;Recently Issued
 Pronouncements &amp;#x2013;&lt;/b&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 is
 evaluating the impact that this new guidance will have on the
 Company&amp;#x2019;s Consolidated Financial Statements.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;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 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: 1px; MARGIN-TOP: 12px"&gt;
 &amp;#xA0;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 0px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;In February 2016, the FASB
 issued ASU 2016-02, 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; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Other than the
 pronouncements discussed above, there are no recently issued
 pronouncements that the Company has not already adopted or that
 have a material impact on the Company.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;&lt;b&gt;Subsequent Events
 &amp;#x2013;&lt;/b&gt; The Company evaluates all events or transactions
 through the date of the related filing.&amp;#xA0;During the period
 through the date of this filing, the Company did not have any
 material subsequent events that impacted its Consolidated Financial

 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Company had 13,966,150,
 13,991,430 and 14,043,280 shares of common stock outstanding at
 March&amp;#xA0;31, 2015,&amp;#xA0;December&amp;#xA0;31, 2015 and March&amp;#xA0;31,

 and Stock Purchase Plan &amp;#x2013;&lt;/b&gt; During the first quarter of
 2016, the Company sold 8,630 shares of its common stock, at an
 average price of $39.19 per share, in connection with its Dividend
 Reinvestment and Stock Purchase Plan (DRP) and its 401(k) plans
 resulting in net proceeds of approximately $338,000. The DRP
 provides participants in the plan a method for investing cash
 dividends on the Company&amp;#x2019;s common stock and cash payments in
 additional shares of the Company&amp;#x2019;s common stock.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;&lt;b&gt;Stock Plan &amp;#x2013;&lt;/b&gt;
 The Company maintains the Unitil Corporation Second Amended and
 Restated 2003 Stock Plan (the Stock Plan). Participants in the
 Stock Plan are selected by the Compensation Committee of the Board
 of Directors to receive awards under the Stock Plan, including
 awards of restricted shares (Restricted Shares), or of restricted
 stock units (Restricted Stock Units). The Compensation Committee
 has the authority to determine the sizes of awards; determine the
 terms and conditions of awards in a manner consistent with the
 Stock Plan; construe and interpret the Stock Plan and any agreement
 or instrument entered into under the Stock Plan as they apply to
 participants; establish, amend, or waive rules and regulations for
 the Stock Plan&amp;#x2019;s administration as they apply to
 participants; and, subject to the provisions of the Stock Plan,
 amend the terms and conditions of any outstanding award to the
 extent such terms and conditions are within the discretion of the
 Compensation Committee as provided for in the Stock Plan. On
 April&amp;#xA0;19, 2012, the Company&amp;#x2019;s shareholders approved an
 amendment to the Stock Plan to, among other things, increase the
 maximum number of shares of common stock available for awards to
 plan participants.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The maximum number of
 shares available for awards to participants under the Stock Plan is
 677,500. The maximum number of shares that may be awarded in any
 one calendar year to any one participant is 20,000. In the event of
 any change in capitalization of the Company, the Compensation
 Committee is authorized to make an equitable adjustment to the
 number and kind of shares of common stock that may be delivered
 under the Stock Plan and, in addition, may authorize and make an
 equitable adjustment to the Stock Plan&amp;#x2019;s annual individual
 award limit.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 18px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;&lt;u&gt;Restricted
 Shares&lt;/u&gt;&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 6px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Outstanding awards of
 Restricted Shares fully vest over a period of four years at a rate
 of 25% each year. During the vesting period, dividends on
 Restricted Shares underlying the award may be credited to a
 participant&amp;#x2019;s account. The Company may deduct or withhold, or
 require a participant to remit to the Company, an amount sufficient
 to satisfy any taxes required by federal, state, or local law or
 regulation to be withheld with respect to any taxable event arising
 in connection with an Award. For purposes of compensation expense,
 Restricted Shares vest immediately upon a participant becoming
 eligible for retirement, as defined in the Stock Plan. Prior to the
 end of the vesting period, the restricted shares are subject to
 forfeiture if the participant ceases to be employed by the Company
 other than due to the participant&amp;#x2019;s death.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;On January&amp;#xA0;26, 2016,
 43,220 Restricted Shares were issued in conjunction with the Stock
 Plan with an aggregate market value at the date of issuance of
 approximately $1.6 million. There were 94,706 and 81,251 non-vested
 shares under the Stock Plan as of March&amp;#xA0;31, 2016 and 2015,
 respectively. The weighted average grant date fair value of these
 shares was $35.24 and $33.15, respectively. The compensation
 expense associated with the issuance of shares under the Stock Plan
 is being recognized over the vesting period and was $1.6 million
 and $1.3 million for the three months ended March&amp;#xA0;31, 2016 and
 2015, respectively. At March&amp;#xA0;31, 2016, there was approximately
 $1.7 million of total unrecognized compensation cost under the
 Stock Plan which is expected to be recognized over approximately
 2.9 years. There were no forfeitures or cancellations under the
 Stock Plan during the three months ended March&amp;#xA0;31,
 2016.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 18px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;&lt;u&gt;Restricted Stock

 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 6px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Restricted Stock Units earn
 dividend equivalents and will generally be settled by payment to
 each Director as soon as practicable following the Director&amp;#x2019;s
 separation from service to the Company. The Restricted Stock Units
 will be paid such that the Director will receive (i)&amp;#xA0;70% of
 the shares of the Company&amp;#x2019;s common stock underlying the
 restricted stock units and (ii)&amp;#xA0;cash in an amount equal to the
 fair market value of 30% of the shares of the Company&amp;#x2019;s
 common stock underlying the Restricted Stock Units. The equity
 portion of Restricted Stock Units activity during the three months
 ended March&amp;#xA0;31, 2016 in conjunction with the Stock Plan are
 presented in the following table:&lt;/font&gt;&lt;/p&gt;

 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,
 2016,&amp;#xA0;March&amp;#xA0;31, 2015 and December&amp;#xA0;31, 2015, the
 Company estimates that the cost of removal amounts, which are

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

 &amp;#x2013;&lt;/b&gt; In the first quarter of 2016, the Company adopted
 Accounting Standards Update (ASU) 2015-03, which requires entities
 to present debt issuance costs related to a debt liability as a
 direct deduction from the carrying amount of that debt liability on
 the balance sheet as opposed to being presented as a deferred
 charge, and ASU 2015-15, which adds paragraphs to ASU 2015-03
 indicating that the SEC staff would not object to an entity
 deferring and presenting debt issuance costs related to
 line-of-credit arrangements as an asset and subsequently amortizing
 the deferred debt issuance costs ratably over the term of the
 line-of-credit arrangement, regardless of whether there are any
 outstanding borrowings on the line-of-credit
 arrangement.&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;For all periods presented
 in this Form 10-Q for the quarter ended March&amp;#xA0;31, 2016,
 unamortized debt issuance costs related to the Company&amp;#x2019;s
 long-term debt are reported on the Consolidated Balance Sheets as a
 reduction of the carrying value of the related debt. Prior to
 adoption, the Company reported the unamortized debt issuance costs
 in &amp;#x201C;Other Assets&amp;#x201D; on the Consolidated Balance Sheets.
 The change in presentation resulted in a reduction of &amp;#x201C;Other
 Assets&amp;#x201D; and &amp;#x201C;Long-Term Debt&amp;#x201D; of $3.1 million and
 $2.9 million as of March&amp;#xA0;31, 2015 and December&amp;#xA0;31, 2015,

 &amp;#x2013; Unitil Corporation (Unitil or the Company) is a public
 utility holding company. Unitil and its subsidiaries are subject to
 regulation as a holding company system by the Federal Energy
 Regulatory Commission (FERC) under the Energy Policy Act of 2005.
 The following companies are wholly-owned subsidiaries of Unitil:

 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Company&amp;#x2019;s
 earnings are seasonal and are typically higher in the first and
 fourth quarters when customers use natural gas for heating
 purposes.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Unitil&amp;#x2019;s principal
 business is the local distribution of electricity in the
 southeastern seacoast and state capital regions of New Hampshire
 and the greater Fitchburg area of north central Massachusetts, and

 transmission pipeline primarily located in Maine and New Hampshire.
 Granite State provides Northern Utilities with interconnection to

 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;A fifth utility subsidiary,
 Unitil Power, formerly functioned as the full requirements
 wholesale power supply provider for Unitil Energy. In connection
 with the implementation of electric industry restructuring in New
 Hampshire, Unitil Power ceased being the wholesale supplier of
 Unitil Energy on May&amp;#xA0;1, 2003 and divested of its long-term
 power supply contracts through the sale of the entitlements to the
 electricity associated with various electric power supply contracts
 it had acquired to serve Unitil Energy&amp;#x2019;s
 customers.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Unitil also has three other
 wholly-owned subsidiaries: Unitil Service; Unitil Realty; and

 New Hampshire and leases this facility to Unitil Service under a
 long-term lease arrangement. Unitil Resources is the
 Company&amp;#x2019;s wholly-owned non-regulated subsidiary. Usource,
 Inc. and Usource L.L.C. (collectively, Usource) are wholly-owned
 subsidiaries of Unitil Resources. Usource provides brokering and
 advisory services to large commercial and industrial customers in
 the northeastern United States.&lt;/font&gt;&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Exchange Gas Obligation
 &amp;#x2013; Northern Utilities enters into gas exchange agreements
 under which Northern Utilities releases certain natural gas
 pipeline and storage assets, resells the natural gas storage
 inventory to an asset manager and subsequently repurchases the
 inventory over the course of the natural gas heating season at the
 same price at which it sold the natural gas inventory to the asset
 manager. The gas inventory related to these agreements is recorded
 in Exchange Gas Receivable on the Company&amp;#x2019;s Consolidated
 Balance Sheets while the corresponding obligations are recorded in
 Energy Supply Obligations.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Renewable Energy Portfolio
 Standards &amp;#x2013; Renewable Energy Portfolio Standards (RPS)
 require retail electricity suppliers, including public utilities,
 to demonstrate that required percentages of their sales are met
 with power generated from certain types of resources or
 technologies. Compliance is demonstrated by purchasing and retiring
 Renewable Energy Certificates (REC) generated by facilities
 approved by the state as qualifying for REC treatment. Unitil
 Energy and Fitchburg purchase RECs in compliance with RPS
 legislation in New Hampshire and Massachusetts for supply provided
 to default service customers. RPS compliance costs are a supply
 cost that is recovered in customer default service rates. Unitil
 Energy and Fitchburg collect RPS compliance costs from customers
 throughout the year and demonstrate compliance for each calendar
 year on the following July&amp;#xA0;1. Due to timing differences
 between collection of revenue from customers and payment of REC
 costs to suppliers, Unitil Energy and Fitchburg typically maintain
 accrued revenue for RPS compliance which is recorded in Accrued
 Revenue with a corresponding liability in Energy Supply Obligations
 on the Company&amp;#x2019;s Consolidated Balance Sheets.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Fitchburg has entered into
 long-term renewable contracts for electric energy and/or renewable
 energy credits. The generating facilities associated with two of
 these contracts have been constructed and are operating. Another
 contract has been approved by the MDPU and is pending facility
 construction and operation, which is anticipated to begin by the
 end of 2016. Fitchburg will recover its costs under this contract
 through a regulatory approved cost tracker rate
 mechanism.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Power Supply Contract
 Divestitures &amp;#x2013; As a result of the restructuring of the
 utility industry in New Hampshire and Massachusetts, Unitil
 Energy&amp;#x2019;s and Fitchburg&amp;#x2019;s customers have the opportunity
 to purchase their electric or natural gas supplies from third-party
 suppliers. In connection with the implementation of retail choice,
 Unitil Power, which formerly functioned as the wholesale power
 supply provider for Unitil Energy, and Fitchburg divested their
 long-term power supply contracts through the sale of the
 entitlements to the electricity sold under those contracts. Unitil
 Energy and Fitchburg recover in their rates all the costs
 associated with the divestiture of their power supply portfolios
 and have secured regulatory approval from the NHPUC and MDPU,
 respectively, for the recovery of power supply-related stranded
 costs. The obligations related to these divestitures are recorded
 in Energy Supply Obligations on the Company&amp;#x2019;s Consolidated
 Balance Sheets with corresponding regulatory assets recorded in
 Accrued Revenue (current portion) and Regulatory Assets (long-term
 portion).&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Massachusetts Green
 Communities Act &amp;#x2013; In compliance with the Massachusetts Green
 Communities Act, discussed below in Note 6, Regulatory Matters,
 Fitchburg has entered into long-term renewable contracts for
 electric energy and/or renewable energy credits. The facility
 associated with two of these contracts has been constructed and is
 operating. The other contracts are pending approval by the MDPU as
 well as subsequent facility construction and operation. These
 facilities are anticipated to begin operation by the end of 2016.
 Fitchburg will recover its costs associated with long-term
 renewable contracts on a fully reconciling basis through a
 MDPU-approved cost recovery mechanism.&lt;/font&gt;&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;&lt;b&gt;Recently Issued
 Pronouncements &amp;#x2013;&lt;/b&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 is
 evaluating the impact that this new guidance will have on the
 Company&amp;#x2019;s Consolidated Financial Statements.&lt;/font&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;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 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: 1px; MARGIN-TOP: 12px"&gt;
 &amp;#xA0;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 0px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;In February 2016, the FASB
 issued ASU 2016-02, 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; MARGIN-TOP: 12px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Other than the
 pronouncements discussed above, there are no recently issued
 pronouncements that the Company has not already adopted or that
 have a material impact on the Company.&lt;/font&gt;&lt;/p&gt;
