Notes To Financial Statements [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	1. Basis of Preparation of Financials The condensed consolidated financial statements included herein have been prepared by Connecticut Water Service, Inc. (the “Company”) and its wholly-owned subsidiaries, pursuant to the rules and regulations of the Securities and Exchange Commission and reflect all adjustments that are of a normal recurring nature which are, in the opinion of management, necessary to a fair statement of the results for interim periods. Certain information and footnote disclosures have been omitted pursuant to such rules and regulations, although the Company believes that the disclosures are adequate to make the information presented not misleading. The Company’s primary operating subsidiaries are: The Connecticut Water Company (“Connecticut Water”) and The Maine Water Company (“Maine Water”). The Condensed Consolidated Balance Sheet at December 31, 2015 has been derived from the audited financial statements at that date but does not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements. It is suggested that these condensed consolidated financial statements be read in conjunction with the financial statements and the notes thereto included in the Company’s latest Annual Report on Form 10-K for the year ended December 31, 2015 (the “10-K”) and as updated in the Company’s Quarterly Report on Form 10-Q for the period ending March 31, 2016. The results for interim periods are not necessarily indicative of results to be expected for the year since the consolidated earnings are subject to seasonal factors. During the preparation of the Condensed Consolidated Financial Statements for the quarter ended June 30, 2016, the Company identified two errors related to the accounting treatment of stock based performance awards granted to officers of the Company. First, the Company had mistakenly classified all stock based performance awards as equity awards and, secondly, incorrectly marked those awards to the market price of the Company’s common stock price at the end of each reporting period. A portion of these awards should have been classified as liability awards and only those awards should have been marked-to-market based on the Company’s common stock price. During the second quarter of 2016, the Company reversed all of the incorrectly recorded mark-to-market expense as a cumulative out-of-period adjustment resulting in a one-time benefit of approximately $2.6 million on the Operation and Maintenance line item on its Condensed Consolidated Statements of Income for the three and six months ended June 30, 2016. Approximately $1.6 million of the out of period adjustment pertained to years prior to 2016, with the remaining $1.0 million related to the first quarter of 2016. Additionally, the Company decreased its Common Stock Without Par Value and increased its Long-Term Compensation Arrangement line items on the Condensed Consolidated Balance Sheet as of June 30, 2016 by approximately $0.6 million to reflect both the awards that should have been classified as liability awards and their corresponding mark-to-market adjustments. The Company performed various quantitative and qualitative analyses and determined that these errors were not material to the previously reported quarterly and annual results. The Company also determined that recording these entries as an out-of- period adjustment during the second quarter of 2016 is not expected to be material to the projected results for the full year ended December 31, 2016. Certain previously reported information has been reclassified to conform to the current period presentation. Regulatory Matters The rates we charge our water customers in Connecticut and Maine are established under the jurisdiction of and are approved by the Connecticut Public Utilities Regulatory Authority (“PURA”) and the Maine Public Utilities Commission (“MPUC”), respectively. It is our policy to seek rate relief as necessary to enable us to achieve an adequate rate of return. Connecticut Water’s allowed return on equity and return on rate base, effective June 30, 2016 , were 9.75% and 7.32% , respectively. Maine Water’s average allowed return on equity and return on rate base, effective June 30, 2016 , were 9.50% and 7.96% , respectively. The PURA establishes rates in Connecticut on a company-wide basis while the MPUC approves Maine Water’s rates on a division-by-division basis. Both Connecticut Water and Maine Water are allowed to add surcharges to customers’ bills in order to recover certain approved capital projects in between full rate cases. Heritage Village Water Company Acquisition On May 10, 2016, the Company entered into an Agreement and Plan of Merger (the “Agreement”) with Heritage Village Water Company, a specially-chartered Connecticut corporation (“HVWC”). Founded in 1969, HVWC is based in Southbury, Connecticut, and serves approximately 4,700 water and 3,000 waste water customers in the southern Connecticut communities of Southbury, Middlebury and Oxford. The Boards of Directors of the Company and HVWC have each unanimously approved the Agreement. Consummation of the Merger is subject to regulatory, HVWC shareholder and other specified approvals described below and is expected to be completed during either the fourth quarter of 2016 or the first quarter of 2017. Under the terms of the Agreement, each share of HVWC common stock issued and outstanding at the time of the closing of the Merger will be exchanged and converted into the right to receive 240 shares of the common stock of the Company, without par value (the “Company Common Stock”), provided that the Company’s Share Price (as defined below) over a specified period prior to the closing date of the Merger is equal to or greater than $39.45 but less than or equal to $41.45. If the the Company’s Share Price is less than $39.45 as of the closing date, each share of HVWC common stock issued and outstanding at the time of the closing of the Merger will be exchanged and converted into the right to receive that number of shares of Company Common Stock equal to $9,468 divided by the Company’s Share Price. If the the Company’s Share Price is more than $41.45 as of the closing date, each share of HVWC common stock issued and outstanding at the time of the closing of the Merger will be exchanged and converted into the right to receive that number of shares of the Company’s Common Stock equal to $9,948 divided by the Company’s Share Price. The “Company’s Share Price” is determined by calculation an average of the closing prices for shares of the Company’s Common Stock on the Nasdaq Stock Market, LLC for the twenty trading days immediately preceding the third business day prior to the closing of the Merger. Holders of HVWC common stock prior to the Merger will receive cash in lieu of fractional shares of Company Common Stock. The Agreement contains customary representations and warranties regarding, on the one hand, HVWC, its business and operations and related matters, and, on the other hand, the Company, made by the parties as of specified dates, and customary affirmative and negative covenants with respect to the conduct of HVWC’s business prior to the closing. In the Agreement, HVWC has agreed that its Board of Directors will, subject to certain exceptions, recommend adoption of the Agreement by HVWC shareholders and the transactions contemplated by the Agreement. HVWC has also agreed: (i) to cause a special meeting of shareholders of HVWC to be held to consider the approval and adoption of the Agreement and the transactions contemplated thereby; and (ii) not to solicit proposals relating to alternative business combination transactions or, subject to certain exceptions, enter into discussions concerning confidential information in connection with alternative business combination transactions. The obligation of the parties to complete the Merger is subject to the satisfaction or waiver on or prior to the closing date of certain specified conditions, including the following: (i) receipt of a final and non-appealable order of PURA approving the Merger in form and substance reasonably acceptable to the parties; (ii) approval of the Merger by the affirmative vote of the holders of not less than two-thirds (66 2/3rd%) HVWC’s issued and outstanding shares of common stock as required under the Connecticut Business Corporation Act and by a super-majority vote of ninety (90%) percent of HVWC’s issued and outstanding shares; (iii) the completion of certain specified corporate governance steps regarding HVWC’s Board of Directors, including the appointment of up to three additional directors; (iv) the receipt of all other necessary consents or approvals to the Merger; (v) approval for listing of the Company Common Stock to be issued in the Merger on the Nasdaq Stock Market, LLC; (vi) the absence of laws, orders, judgments and injunctions that restrain, enjoin or otherwise prohibit consummation of the Merger; (vii) effectiveness under the Securities Act of 1933 (the “Securities Act”) of the Company’s registration statement on Form S-4 relating to the issuance of the Company Common Stock in the Merger and absence of any stop order in respect thereof or proceedings by the Securities and Exchange Commission (“SEC”) for that purpose; (viii) the receipt of customary tax opinions from counsel to HVWC and the Company that will state that the Merger will qualify as a tax-free reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986; (ix) the accuracy of representations and warranties with respect to the businesses of HVWC and the Company and compliance by HVWC and the Company with their respective covenants contained in the Merger Agreement; (x) no event(s) occurring that could reasonably be expected to result in a “Company Material Adverse Effect” (as defined in the Agreement) and (xi) holders of no more than 5% of HVWC’s common stock have exercised appraisal rights under Connecticut law. The parties’ obligation to complete the Merger is also subject to a closing condition related to HVWC’s enabling legislation adopted in 1969. The special act of the Connecticut legislature that formed HVWC provides a right of first refusal (“ROFR”) to the Town of Southbury, Connecticut to purchase HVWC on the same terms and conditions as those set forth in the Agreement. The Town has a statutory period of ninety (90) days following receipt of notice from HVWC to exercise its right to purchase HVWC on such same terms and conditions. This notice was delivered to the Town on May 10, 2016. The Agreement contains certain termination rights for both the Company and HVWC and further provides that, in connection with the termination of the Agreement under specified circumstances, HVWC may be required to pay to the Company, or the Company may be required to pay to HVWC, a termination fee of $100,000 in cash, as liquidated damages. On July 7, 2016, Connecticut Water filed an application with PURA seeking approval of the acquisition. On July 28, 2016, the Town of Southbury filed a lawsuit against HVWC and Connecticut Water in Connecticut state court seeking a preliminary injunction to preclude the parties from completing the merger or taking other actions that the Town believes will prevent the Town from fully enforcing its ROFR rights. On August 5, 2016, a hearing was held in Waterbury Superior Court at which the Court ordered that its ROFR deadline be extended to November 11, 2016. The order allows the Company to continue the approval process, with both state utility regulators and the SEC. Maine Water Land Sale On March 11, 2016, Maine Water entered into a purchase and sale agreement with the Coastal Mountains Land Trust, a Maine nonprofit corporation (the “Land Trust”) pursuant to which Maine Water agreed to sell two conservation easements to the Land Trust on approximately 1,300 acres of land located in the towns of Rockport, Camden and Hope, in Knox County, Maine valued in the aggregate at $3.1 million. The land had a book value of approximately $600,000 at December 31, 2015 and is included in “Utility Plant” on the Company’s “Consolidated Balance Sheets”. The easements and purchase prices are as follows: 1. Ragged Mountain Mirror Lake Conservation Easement: $1,875,000; and 2. Grassy Pond conservation Easement: $600,000. The two easement sale and donation transactions are expected to close no later than December 31, 2017 and December 31, 2019, respectively. Maine Water will make a $200,000 contribution to the Land Trust upon completion of the closing of the first easement sale. Maine Water also expects to claim a charitable deduction for the $600,000 in excess of the fair market value of the second easement over the $600,000 sale price. Connecticut Rates In Connecticut, the Water Infrastructure Conservation Adjustment (“WICA”) was 3.04% and 5.12% at June 30, 2015 and 2016 , respectively. On July 27, 2016, Connecticut Water filed a WICA application with the PURA requesting a 2.01% surcharge to customers’ bills, representing approximately $12.8 million in WICA related projects. If approved as filed, the Company’s cumulative WICA surcharge, effective October 1, 2016, will be 7.13%. WICA surcharges are capped at 10% between general rate cases. Since 2013, Connecticut law has authorized a Water Revenue Adjustment (“WRA”) to reconcile actual water demands with the demands projected in the last general rate case and allows companies to adjust rates as necessary to recover the revenues approved by PURA in the last general rate case. The WRA removes the financial disincentive for water utilities to develop and implement effective water conservation programs. The WRA allows water companies to defer on the balance sheet, as a regulatory asset or liability, for later collection from or crediting to customers the amount by which actual revenues deviate from the revenues allowed in the most recent general rate proceedings, including WICA proceedings. Additionally, projects eligible for WICA surcharges were expanded to include energy conservation projects, improvements required to comply with streamflow regulations, and improvements to acquired systems. Connecticut Water’s allowed revenues for the six months ended June 30, 2016 , as approved by PURA during our 2010 general rate case and including subsequently approved WICA surcharges, are approximately $36.8 million. Through normal billing for the six months ended June 30, 2016 , revenue for Connecticut Water would have been approximately $34.0 million had the WRA not been implemented. As a result of the implementation of the WRA, Connecticut Water recorded $2.8 million in additional revenue for the six months ended June 30, 2016 . Maine Rates In Maine, the overall, cumulative Water Infrastructure Charge (“WISC”) for all divisions was 1.13% and 4.08% as of June 30, 2015 and 2016, respectively. In 2014 and 2015, Maine Water petitioned the MPUC for approval of accounting orders that would address (1) the return to its customers a federal income tax refund stemming from the adoption of the Internal Revenue Service (“IRS”) Revenue Procedure 2012-19 (“Repair Regulations”), and (2) the treatment of any benefit resulting from the elimination of deferred tax liabilities previously recorded on these qualifying fixed assets that are now deducted under these new repair regulations. On February 26, 2015, the MPUC approved a stipulation between Maine Water and the Office of the Public Advocate that refunds $2.9 million to the customers of the eight divisions over a two year period starting no later than July 1, 2015, and allows the flow-through treatment of the repair deduction as of January 1, 2014. In addition, Maine Water agreed not to file a general rate case during the two year refund period in any of the eight divisions that were allowed the refund. On June 22, 2015, the MPUC approved a settlement agreement between Maine Water and the Office of the Public Advocate that allowed for the amortization of the deferred tax liabilities over a one to nine year period, depending on the division. Maine Water commenced amortization per the agreed upon schedule. With the completion of these two dockets, Maine Water recorded in the quarter ended June 30, 2015 the retroactive benefit associated with the flow-through of Repair Regulations from January 1, 2014. The 2014 benefit, reflected in the second quarter of 2015, was approximately $931,000, or $0.09 per basic share outstanding. A newly passed water revenue adjustment mechanism law in Maine became available to regulated water utilities in Maine on October 15, 2015. Maine Water is currently precluded from seeking new rates due to various agreements with the MPUC, but is evaluating how and when this new mechanism can be implemented.

New Accounting Pronouncements

New Accounting Pronouncements	6 Months Ended

Notes To Financial Statements [Abstract]
Recently Adopted and New Accounting Pronouncements	4. Recently Adopted and New Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers,” (“No. 2014-09”) which amends its guidance related to revenue recognition. ASU No. 2014-09 requires an entity to recognize revenue as performance obligations are met, in order to reflect the transfer of promised goods or services to customers in an amount that reflects the consideration the entity is entitled to receive for those goods or services. The following steps are applied in the updated guidance: (1) identify the contract(s) with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when, or as, the entity satisfies a performance obligation. ASU No. 2014-09 is effective for public companies for fiscal years, and interim periods within those years, beginning after December 15, 2016, and can be adopted either retrospectively to each prior reporting period presented or as a cumulative-effect adjustment as of the date of adoption, however early adoption is not permitted. On April 1, 2015, the FASB voted for a one-year deferral of the effective date of ASU No. 2014-09, making ASU No. 2014-09 effective for public companies for fiscal years, and interim periods within those years, beginning after December 15, 2017. The Company is currently determining its implementation approach and assessing the impact that this guidance may have on our consolidated financial position, including its impact on the Company’s contracted services provided to water and wastewater utilities. In April 2015, the FASB issued ASU 2015-03, “Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs” (“ASU No. 2015-03”). The update requires debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of the related debt liability instead of being presented as an asset. Debt disclosures will include the face amount of the debt liability and the effective interest rate. The update requires retrospective application and represents a change in accounting principle. The update is effective for fiscal years beginning after December 15, 2015. The Company has adopted ASU No. 2015-03, effective January 1, 2016, which had the effect of reducing the December 31, 2015 Long-Term Debt balance by $5,786,000 on the Condensed Consolidated Balance Sheet. In July 2015, the FASB issued ASU 2015-11, “Inventory (Topic 330): Simplifying the Measurement of Inventory,” (“ASU No. 2015-11”) which applies to inventory that is measured using first-in, first-out (“FIFO”) or average cost. Under the updated guidance, an entity should measure inventory that is within scope at the lower of cost or net realizable value, which is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. Subsequent measurement is unchanged under the updated guidance for inventory that is measured using last-in, last-out (“LIFO”). This ASU is effective for annual and interim periods beginning after December 15, 2016, and should be applied prospectively with early adoption permitted at the beginning of an interim or annual reporting period. The Company uses average cost to value its inventory and, therefore, ASU No. 2015-11 is expected to have no impact on the Company. In November 2015, the FASB issued ASU No. 2015-17, “Income Taxes (Topic 740), Balance Sheet Classification of Deferred Taxes” (“ASU No. 2015-17”). ASU No. 2015-17 requires net deferred tax assets and liabilities to be classified as non-current on the Company’s Consolidated Balance Sheets. Prior to adoption of the new standard, net deferred tax assets and liabilities were presented separately as current and non-current on the Consolidated Balance Sheets. ASU No. 2015-17 is effective for financial statements issued for annual periods beginning after December 15, 2016 and interim periods within those annual periods. Early adoption is permitted. The Company has adopted ASU No. 2015-17, effective January 1, 2016, which had the effect of reducing the December 31, 2015 Prepayments and Other Current Assets and Deferred Federal and State Income Taxes balances by $17,000 on the Condensed Consolidated Balance Sheet. In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842)”, (“ASU No. 2016-02”), which will require lessees to recognize the following for all leases at the commencement date of a lease: a) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and b) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Public business entities should apply the amendments in ASU No. 2016-02 for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application is permitted for all public business entities and all nonpublic business entities upon issuance. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Lessees and lessors may not apply a full retrospective transition approach. The Company is currently assessing the impact of this standard on its consolidated financial statements and footnote disclosures, but does not expect that the adoption of this guidance will materially impact our consolidated financial position. In March 2016, the FASB issued ASU 2016-09, “Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting” (“ASU No. 2016-09”). ASU No. 2016-09 impacts several aspects of the accounting for share-based payment transactions, including classification of certain items on the Consolidated Statement of Cash Flows and accounting for income taxes. Specifically, ASU No. 2016-09 requires that excess tax benefits and tax deficiencies (the difference between the deduction for tax purposes and the compensation cost recognized for financial reporting purposes) be recognized as income tax expense or benefit in the Consolidated Statements of Income, introducing a new element of volatility to the provision for income taxes. ASU No. 2016-09 is effective for fiscal years beginning after December 15, 2016, with early adoption permitted. The Company adopted ASU No. 2016-09 during the second quarter of 2016, which had the effect of decreasing the Other line item on the Condensed Consolidated Statement of Income for the three and six months ended June 30, 2016 by approximately $19,000.

Fair Value Disclosures

Fair Value Disclosures	6 Months Ended
	Jun. 30, 2016
Notes To Financial Statements [Abstract]
Fair Value Disclosures	Fair Value Disclosures FASB Accounting Standards Codification (“ASC”) 820, Fair Value Measurements and Disclosures (“FASB ASC 820”) provides enhanced guidance for using fair value to measure assets and liabilities and expands disclosure with respect to fair value measurements. FASB ASC 820 establishes a fair value hierarchy that distinguishes between assumptions based on market data (observable inputs) and the Company’s assumptions (unobservable inputs). The hierarchy consists of three broad levels, as follows: Level 1 – Quoted market prices in active markets for identical assets or liabilities. Level 2 – Inputs other than Level 1 that are either directly or indirectly observable. Level 3 – Unobservable inputs developed using the Company’s estimates and assumptions, which reflect those that the Company believes market participants would use. The following table summarizes our financial instruments measured at fair value on a recurring basis within the fair value hierarchy as of June 30, 2016 (in thousands): Level 1 Level 2 Level 3 Total Asset Type: Company Owned Life Insurance $ — $ 2,989 $ — $ 2,989 Money Market Fund 123 — — 123 Mutual Funds: Equity Funds (1) 1,364 — — 1,364 Fixed Income Funds (2) 469 — — 469 Total $ 1,956 $ 2,989 $ — $ 4,945 The following table summarizes our financial instruments measured at fair value on a recurring basis within the fair value hierarchy as of December 31, 2015 (in thousands): Level 1 Level 2 Level 3 Total Asset Type: Company Owned Life Insurance $ — $ 2,909 $ — $ 2,909 Money Market Fund 122 — — 122 Mutual Funds: Equity Funds (1) 1,441 — — 1,441 Fixed Income Funds (2) 485 — — 485 Total $ 2,048 $ 2,909 $ — $ 4,957 (1) Mutual funds consist primarily of equity securities and are presented on the Other Property and Investments line item of the Company’s Condensed Consolidated Balance Sheets. (2) Mutual funds consist primarily of fixed income securities and are presented on the Other Property and Investments line item of the Company’s Condensed Consolidated Balance Sheets. The fair value of Company Owned Life Insurance is based on the cash surrender value of the contracts. These contracts are based principally on a referenced pool of investment funds that actively redeem shares and are observable and measurable and are presented on the Other Property and Investments line item of the Company’s Condensed Consolidated Balance Sheets. The following methods and assumptions were used to estimate the fair value of each of the following financial instruments, which are not recorded at fair value on the financial statements. Cash and cash equivalents – Cash equivalents consist of highly liquid instruments with original maturities at the time of purchase of three months or less. The carrying amount approximates fair value. Under the fair value hierarchy the fair value of cash and cash equivalents is classified as a Level 1 measurement. Restricted Cash – As part of Maine Water’s November 2015 bond offering, the Company recorded unused proceeds from this bond issuance as restricted cash as the funds can only be used for certain capital expenditures. The Company expects to use the remainder of the proceeds during 2016, as the approved capital expenditures are completed. The carrying amount approximates fair value. Under the fair value hierarchy the fair value of restricted cash is classified as a Level 1 measurement. Long-Term Debt – The fair value of the Company’s fixed rate long-term debt is based upon borrowing rates currently available to the Company. As of June 30, 2016 and December 31, 2015 , the estimated fair value of the Company’s long-term debt was $227,057,000 and $191,616,000 , respectively, as compared to the carrying amounts of $206,399,000 and $177,654,000 , respectively. The estimated fair value of long term debt was calculated using a discounted cash flow model that uses comparable interest rates and yield curve data based on the A-rated MMD (Municipal Market Data) Index which is a benchmark of current municipal bond yields. Under the fair value hierarchy, the fair value of long term debt is classified as a Level 2 measurement. Advances for Construction – Customer advances for construction had a carrying amount of $20,720,000 and $21,444,000 at June 30, 2016 and December 31, 2015 , respectively. Their relative fair values cannot be accurately estimated since future refund payments depend on several variables, including new customer connections, customer consumption levels and future rate increases. The fair values shown above have been reported to meet the disclosure requirements of FASB ASC 825, “Financial Instruments” (“FASB ASC 825”) and do not purport to represent the amounts at which those obligations would be settled.

Income Tax Expense

Notes To Financial Statements [Abstract]
Income Taxes	Income Taxes FASB ASC 740 Income Taxes (“FASB ASC 740”) addresses the determination of how tax benefits claimed or expected to be claimed on a tax return should be recorded in the financial statements. Under FASB ASC 740, the Company must recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate resolution. On June 11, 2013, the Company was notified by the Connecticut Department of Revenue Services that its state tax filings for the years 2009 through 2011 would be reviewed beginning in the fourth quarter of 2013. On March 24, 2015, the Company was notified by the Connecticut Department of Revenue Services that the audit was expanded to include the 2012 and 2013 tax years. The State focused its review on tax credits associated with fixed capital investment. The Company and the State came to an agreement (“Closing Agreement”) regarding investments eligible for the credit. The Closing Agreement was executed on May 4, 2015. The Company had previously recorded a provision for the possible disallowance of these credits and, therefore, there was minimal impact in 2015. On the 2012 tax return, filed in September 2013, Connecticut Water filed a change in accounting method to adopt the Internal Revenue Service’s (“IRS”) temporary tangible property regulations. On the 2013 Federal tax return, filed in September 2014, Maine Water filed the same change in accounting method. This method change allowed the Company to take a current year deduction for expenses that were previously capitalized for tax purposes. Since the filing of the 2012 tax return, the IRS has issued final regulations. On February 11, 2014, the Company was notified by the IRS that its Federal tax filing for 2012 would be reviewed. This review, which began in the first quarter of 2014 and was completed in the first quarter of 2015, resulted in no change to the tax liability. Since the Company had previously recorded a provision for the possible disallowance of the repair deduction in prior periods, the completion of the audit resulted in the reversal of the provision in the amount of $1,185,000 in the first quarter of 2015. While the Company maintains the belief that the deduction taken on its tax return is appropriate, the methodology for determining the deduction has not been agreed to by the taxing authorities. Through June 30, 2016 , the Company has recorded, as required by FASB ASC 740, a provision of $1.1 million for a portion of the benefit that is not being returned to customers resulting from any possible tax authority challenge. The Company had previously recorded a provision of $6.3 million in the prior year for a cumulative total of $7.4 million. From time to time, the Company may be assessed interest and penalties by taxing authorities. In those cases, the charges would appear on the Other line item within the Other Income (Deductions), Net of Taxes section of the Company’s Condensed Consolidated Statements of Income. There were no such charges for the six months ended June 30, 2016 and 2015 . Additionally, there were no accruals relating to interest or penalties as of June 30, 2016 and December 31, 2015 . The Company remains subject to examination by federal tax authorities for the 2013 and 2014 tax years; the State of Maine’s tax authorities for the 2012 through 2014 tax years; and the State of Connecticut’s tax authorities for the 2014 tax year. The Company is currently engaged in an analysis to determine the amount of expenditures related to tangible property that will be reflected on its 2016 Federal Tax Return to be filed in September 2017. As a result, through the second quarter of 2016 , the Company has estimated the portion of its infrastructure investment that will qualify as a repair deduction for 2016 and has reflected that deduction in its effective tax rate, net of any reserves. Consistent with other differences between book and tax expenditures, the Company is required to use the flow-through method to account for any timing differences not required by the IRS to be normalized. The Company’s effective income tax rate for the three months ended June 30, 2016 and 2015 was 7.4% and 6.4% , respectively. The Company’s effective tax rate, excluding discrete items recorded during the three months ended June 30, 2016 , was 5.2% . These discrete items include adjustments related to uncertain tax positions for the repair deduction in both Connecticut and Maine and a change in estimate of prior year tax expense. The blended Federal and State statutory income tax rates during each period were 41% . In determining its annual estimated effective tax rate for interim periods, the Company reflects its estimated permanent and flow-through tax differences for the taxable year, including the basis difference for the adoption of the tangible property regulations. The Company’s effective income tax rate for the six months ended June 30, 2016 and 2015 was 8.0% and (1.7)% , respectively. The Company’s effective tax rate, excluding discrete items recorded during the six months ended June 30, 2016 , was 3.4% . These discrete items include adjustments related to uncertain tax positions for the repair deduction in both Connecticut and Maine and a change in estimate of prior year tax expense. The blended Federal and State statutory income tax rates during each period were 41% . In determining its annual estimated effective tax rate for interim periods, the Company reflects its estimated permanent and flow-through tax differences for the taxable year, including the basis difference for the adoption of the tangible property regulations.
