| Organization, Consolidation and Presentation of Financial Statements Disclosure and Significant Accounting Policies [Text Block] | NOTE 1: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES BASIS OF PRESENTATION – The Consolidated Financial Statements include the operations of Connecticut Water Service, Inc. (the “Company”), an investor-owned holding company and its wholly-owned subsidiaries, including: The Connecticut Water Company (“Connecticut Water”) The Maine Water Company (“Maine Water”) Chester Realty, Inc. (“Chester Realty”) New England Water Utility Services, Inc. (“NEWUS”) The Barnstable Holding Company (“Barnstable Holding”) - Inactive As of December 31, 2016 , Connecticut Water and Maine Water were our regulated public water utility companies (collectively the “Regulated Companies”), which together served 124,968 customers in 77 towns throughout Connecticut and Maine. Chester Realty is a real estate company whose net profits from rental of property are included in the “Other Income (Deductions), Net of Taxes” section of the Consolidated Statements of Income in the “Non-Water Sales Earnings” category. NEWUS is engaged in water-related services, including the Linebacker ® program, emergency drinking water, pool water and contract operations. Its earnings are included in the “Non-Water Sales Earnings” category of the Consolidated Statements of Income. Intercompany accounts and transactions have been eliminated. 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 a portion of its 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 months ended June 30, 2016 and $1.6 million for the 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 was not material to the full year ended December 31, 2016 results of operations. PUBLIC UTILITY REGULATION – Connecticut Water is subject to regulation for rates and other matters by the Connecticut Public Utility Regulatory Authority (“PURA”) and follows accounting policies prescribed by the PURA. Maine Water is subject to regulation for rates and other matters by the Maine Public Utilities Commission (“MPUC”). The Company prepares its financial statements in accordance with accounting principles generally accepted in the United States of America (“GAAP”), which includes the provisions of Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) 980 “Regulated Operations” (“FASB ASC 980”). FASB ASC 980 requires cost-based, rate-regulated enterprises, such as Connecticut Water and Maine Water, to reflect the impact of regulatory decisions in their financial statements. The state regulators, through the rate regulation process, can create regulatory assets and liabilities that result when costs and benefits are allowed for ratemaking purposes in a period after the period in which the costs or benefits would be charged to expense by an unregulated enterprise. The Consolidated Balance Sheets include regulatory assets and liabilities as appropriate, primarily related to income taxes, post-retirement benefit costs and deferred revenues associated with the Water Revenue Adjustment (“WRA”) used by Connecticut Water. In accordance with FASB ASC 980, costs which benefit future periods are amortized over the periods they benefit. The Company believes, based on current regulatory circumstances, that the regulatory assets recorded are probable to be recovered and that its use of regulatory accounting is appropriate and in accordance with the provisions of FASB ASC 980. Regulatory assets and liabilities are comprised of the following: (in thousands) December 31, 2016 2015 Assets: Pension Benefits and Post-Retirement Benefits Other Than Pension $ 12,531 $ 12,882 Unrecovered Income Taxes 93,264 77,510 Deferred revenue (included in Prepayments and Other Current Assets and Deferred Charges and Other Costs) 3,910 5,033 Other (included in Prepayments and Other Current Assets and Deferred Charges and Other Costs) 4,276 3,561 Total regulatory assets $ 113,981 $ 98,986 Liabilities: Other (included in Other Current Liabilities) $ 1,710 $ 1,567 Unamortized Investment Tax Credits 1,189 1,264 Refunds to Customers (including Current Portion of Refund to Customers) 963 3,987 Unfunded Future Income Taxes (including Other Long-Term Liabilities) 90,977 74,712 Total regulatory liabilities $ 94,839 $ 81,530 Pension and post-retirement benefits include costs in excess of amounts funded. The Company believes these costs will be recoverable in future years, through rates, as funding is required and has recorded regulatory assets for those costs. The recovery period is dependent on contributions made to the plans and remaining life expectancy. Certain items giving rise to deferred state income taxes, as well as a portion of deferred federal income taxes related primarily to differences between book and tax depreciation expense, are recognized for ratemaking purposes on a cash or flow-through basis and are recognized as unrecovered future income taxes that will be recovered in rates in future years as they reverse. In addition, basis differences resulting from the repair tax deduction adopted in 2013 contribute to the change in unfunded future income taxes. Deferred revenue represents a portion of the rate increase granted in Connecticut Water’s 2007 rate decision. The PURA decision required the Company to defer for future collection, beginning in 2008, a portion of the increase. Additionally, revenue recorded under the WRA, discussed below, is included in deferred revenue. Regulatory liabilities include deferred investment tax credits and amounts to be refunded to customers as a result of the adoption of the tangible property regulations in Connecticut and Maine. These liabilities will be given back to customers in rates as tax deductions occur in the future. Regulatory Matters The rates we charge our customers in Connecticut and Maine are established under the jurisdiction of and are approved by the PURA and 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 as of December 31, 2016 were 9.75% and 7.32% , respectively. Maine Water’s average allowed return on equity and return on rate base, as of December 31, 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 permitted to add surcharges to customers’ bills in order to recover certain approved capital projects in between full rate cases, as well as approved surcharges for Water Revenue Adjustments in Connecticut, as discussed in more detail below. University of Connecticut Agreement Connecticut Water and the University of Connecticut (“UCONN”) negotiated a definitive agreement for Connecticut Water to provide a long-term supply of potable water for UCONN’s Storrs campus facilities which was approved by the Board of Trustees at their December 11, 2013 meeting and executed on December 18, 2013. The definitive agreement is consistent with the requirements of the project’s Environmental Impact Evaluation (“EIE”) and record of decision, as approved by the Office of Policy and Management, an agency of the State of Connecticut, that identified the Company as the preferred option to supply UCONN and the Town of Mansfield, Connecticut with up to 2.2 million gallons of water per day over the next 47 years. Connecticut Water will fund a 5-mile pipeline from Tolland and other necessary infrastructure improvements at no cost to UCONN, the Town or the state’s taxpayers to serve the area. The Company was responsible for obtaining any required regulatory permits, licenses and approvals to implement the water supply solution, including but not limited to those from PURA, the Connecticut Department of Energy and Environmental Protection (“DEEP”) and the Connecticut Department of Public Health (“DPH”). The capital improvements were completed on time and the pipeline was connected to the UCONN campus in December 2016, which was within the agreed upon timeframe. Town of Mansfield Agreement Connecticut Water and the Town of Mansfield entered into an agreement for Connecticut Water to serve the Town of Mansfield community. On January 13, 2014, the Mansfield Town Council voted to authorize the Town Manager to execute the agreement with Connecticut Water and it was signed by the parties on January 21, 2014. The key provisions of the agreement with the Town of Mansfield are as follows: • Current off-campus customers of UCONN will become customers of Connecticut Water at UCONN’s water rates in effect at that time (subject to any state-approved surcharges); • Future water customers in the Town of Mansfield will be served by Connecticut Water at the rates authorized by the PURA; • Connecticut Water will assume responsibility for maintaining, repairing and replacing the off-campus water system serving the Town of Mansfield; • Connecticut Water will make any source or system improvements to meet current and future water supply needs of the area; and • Pursuant to the Agreement, a Water System Advisory Committee (“WSAC”) was created with representatives of the Town of Mansfield, UCONN, regional representatives and other key stakeholders to advise Connecticut Water regarding water service and the system’s operations, expansion or integration as well as recommended best management practices, including water conservation programs. The WSAC meets quarterly. The former off-campus customers of UCONN in the Town of Mansfield became customers of Connecticut Water in December 2016. Avon Water Company Acquisition On October 11, 2016, the Company entered into an Agreement and Plan of Merger (the “Avon Agreement”) with The Avon Water Company, a specially-chartered Connecticut corporation (“Avon Water”). Founded in 1911, Avon Water serves about 4,800 customers in the Farmington Valley communities of Avon, Farmington, and Simsbury, Connecticut, and is located near Connecticut Water’s existing operations in Avon and Farmington. The Boards of Directors of the Company and Avon Water have each unanimously approved the Avon Agreement and the transactions contemplated thereby. Consummation of the merger is subject to regulatory, Avon Water shareholder and other specified approvals described below and is expected to be consummated by the end of the third quarter of 2017. Under the terms of the Avon Agreement, each of the 121,989 Avon Water common stock shares outstanding at the time of the closing of the merger will be exchanged and converted into the right to receive the following merger consideration: (i) a cash payment of $50.37; and (ii) a stock consideration component, consisting of 4.38 shares of 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 $45.00 but less than or equal to $52.00. If the Company’s Share Price is less than $45.00 as of the closing date, each share of Avon Water 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 197.10 divided by the Company’s Share Price, rounded to the nearest hundredth. If the Company’s Share Price is more than $52.00 as of the closing date, each share of Avon Water 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 227.76 divided by the Company’s Share Price, rounded to the nearest hundredth. The “Company’s Share Price” is determined by calculating 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 Avon Water common stock prior to the Merger will receive cash in lieu of fractional shares of Company Common Stock. The Avon Agreement contains customary representations and warranties regarding, on the one hand, Avon Water, 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 Avon Water’s business prior to the closing. In the Avon Agreement, Avon Water has agreed that its Board of Directors will, subject to certain exceptions, recommend adoption of the Avon Agreement by Avon Water shareholders and the transactions contemplated by the Avon Agreement. Avon Water has also agreed: (i) to cause a special meeting of shareholders of Avon Water 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 final and non-appealable orders from each of PURA and the MPUC 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 2/3 rd %) Avon Water’s issued and outstanding shares of common stock as required under the Connecticut Business Corporation Act; (iii) the receipt of all other necessary consents or approvals to the merger; (iv) approval for listing of the Company Common Stock to be issued in the merger on the Nasdaq Stock Market, LLC; (v) the absence of laws, orders, judgments and injunctions that restrain, enjoin or otherwise prohibit consummation of the Merger; (vi) effectiveness under 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 SEC for that purpose; (vii) the receipt of a legal opinion from counsel to Avon Water regarding certain corporate law matters; (viii) the receipt of a customary tax opinion from counsel to 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 Avon Water and the Company and compliance by Avon Water and the Company with their respective covenants contained in the Avon Agreement; (xi) no event(s) occurring that could reasonably be expected to result in either a “Company Material Adverse Effect” or a “CWS Material Adverse Effect” (each, as defined in the Avon Agreement) and (xii) holders of no more than 5% of Avon Water’s common stock have exercised appraisal rights under Connecticut law. The Avon Agreement contains certain termination rights for both the Company and Avon Water and further provides that, in connection with the termination of the Avon Agreement under specified circumstances, Avon Water may be required to pay to the Company, or the Company may be required to pay to Avon Water, a termination fee of $200,000 in cash, as liquidated damages. During the fourth quarter of 2016, Connecticut Water filed an application with PURA seeking approval of the transaction, which the Company expects to receive in April 2017. 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 7.13%, 4.19% and 1.59% above base rates at December 31, 2016, 2015, and 2014 , respectively. On January 26, 2017, Connecticut Water filed a WICA application with the PURA requesting a 1.09% surcharge to customers’ bills, representing approximately $8.5 million in WICA related projects. Additionally, on February 9, 2017, Connecticut Water filed its annual WICA reconciliation which requested a 0.06% surcharge, which would replace the 0.03% reconciliation adjustment filed in January 2016. If approved as filed, Connecticut Water’s cumulative WICA surcharge, effective April 1, 2017, will be 8.25%. Since 2013, Connecticut law has authorized a 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 year ended December 31, 2016 , as approved by PURA during our 2010 general rate case and including subsequently approved WICA surcharges, were approximately $76.7 million. Through normal billing for the year ended December 31, 2016 operating revenue for Connecticut Water would have been approximately $75.6 million had the WRA not been implemented. As a result of the implementation of the WRA, Connecticut Water recorded $1.1 million in additional revenue for the year ended December 31, 2016 . During the year ended December 31, 2015 and 2014 , Connecticut Water recorded $1.6 million and $3.7 million , respectively, in additional revenue related to the WRA. Maine Rates In Maine, the overall, approved cumulative Water Infrastructure Charge (“WISC”) for all divisions was 4.7%, 1.6% and 2.0% above base rates as of December 31, 2016, 2015 and 2014, respectively. Two pending WISC filings as of December 31, 2016 have since been approved in the first quarter of 2017, bringing the total to 6.5%. 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 the 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 the 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 in certain divisions due to various agreements with the MPUC, but is evaluating how and when this new mechanism can be implemented. USE OF ESTIMATES – The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from these estimates. REVENUES – The Company’s accounting policies regarding revenue recognition by segment are as follows: Water Operations – Most of our water customers are billed quarterly, with the exception of larger commercial and industrial customers, as well as certain public and private fire protection customers who are billed monthly. Most customers, except fire protection customers, are metered. Revenues from metered customers are based on their water usage multiplied by approved, regulated rates and are earned when water is delivered. Public fire protection revenues are based on the length of the water main, and number of hydrants in service and are earned on a monthly basis. Private fire protection charges are based on the diameter of the connection to the water main. Our Regulated Companies accrue an estimate for metered customers for the amount of revenues earned relating to water delivered but unbilled at the end of each quarter, which is reflected as “Accrued Unbilled Revenues” in the accompanying Consolidated Balance Sheets. Beginning in 2013, Connecticut Water began to record deferred revenue to represent under collection from customers based upon allowed revenues as approved by PURA. More detailed information, including revenues, costs and income taxes associated with the segment can be found in Note 14, “Segment Reporting”. Real Estate Transactions – Revenues are recorded when a sale or other transaction has been completed and title to the real estate has been transferred. Net income from the Real Estate Transactions segment is shown net in the “Other Income (Deductions), Net of Taxes” portion of the Company’s Consolidated Statements of Income. More detailed information, including revenues, costs and income taxes associated with the segment can be found in Note 14, “Segment Reporting”. Services and Rentals – Revenues are recorded when the Company has delivered the services called for by contractual obligation. Net income from the Services and Rentals segment is shown net in the “Other Income (Deductions), Net of Taxes” portion of the Company’s Consolidated Statements of Income. More detailed information, including revenues, costs and income taxes associated with the segment can be found in Note 14, “Segment Reporting”. UTILITY PLANT – Utility plant is stated at the original cost of such property when first devoted to public service. Utility plant accounts are charged with the cost of improvements and replacements of property including an Allowance for Funds Used During Construction (“AFUDC”). Retired or disposed depreciable plant is charged to accumulated provision for depreciation together with any costs applicable to retirement, less any salvage received. Maintenance of utility plant is charged to expense. Accounting policies relating to other areas of utility plant are listed below: Allowance For Funds Used During Construction – AFUDC is the cost of debt and equity funds used to finance the construction of utility plant. The amount shown on the Consolidated Statements of Income relates to the equity portion. The debt portion is included as an offset to “Other Interest Income, Net”. Generally, utility plant under construction is not recognized as part of rate base for ratemaking purposes until facilities are placed into service, and accordingly, AFUDC is charged to the construction cost of utility plant. Capitalized AFUDC, which does not represent current cash income, is recovered through rates over the service lives of the assets. Our Regulated Companies’ allowed rate of return on rate base is used to calculate AFUDC. Customers’ Advances For Construction, Contributed Plant and Contributions In Aid Of Construction –Under the terms of construction contracts with real estate developers and others, the Regulated Companies periodically receive either advances for the costs of new main installations or title to the main after it is constructed and financed by the developer. Refunds are made, without interest, as services are connected to the main, over periods not exceeding fifteen years and not in excess of the original advance. Unrefunded balances, at the end of the contract period, are credited to contributions in aid of construction (“CIAC”) and are no longer refundable. Utility Plant is added in two ways. The majority of the Company’s plant additions occur from direct investment of Company funds that originated through operating or financings activities. The Company manages the construction of these plant additions. These plant additions are part of the Company’s depreciable utility plant and are generally part of rate base. The Company’s rate base is a key component of how its regulated rates are set, and is recovered through the depreciation component of the Company’s rates. The second way in which plant additions occur are through developer advances and contributions. Under this scenario either the developer funds the additions through payments to the Company, who in turn manages the construction of the project, or the developer pays for the plant construction directly and contributes the asset to the Company after it is complete. Plant additions that are financed by a developer, either directly or indirectly, are excluded from the Company’s rate base and not recovered through the rates process, and are also not depreciated. The components that comprise net additions to Utility Plant during the last three years ending December 31 are as follows: (in thousands) 2016 2015 2014 Additions to Utility Plant: Company Financed $ 66,339 $ 47,774 $ 44,969 Allowance for Funds Used During Construction 1,198 530 518 Subtotal – Utility Plant Increase to Rate Base 67,537 48,304 45,487 Advances from Others for Construction 350 251 699 Net Additions to Utility Plant $ 67,887 $ 48,555 $ 46,186 Depreciation – Depreciation is computed on a straight-line basis at various rates as approved by the state regulators on a company by company basis. Depreciation allows the Company to recover the investment in utility plant over its useful life. The overall consolidated company depreciation rate, based on the average balances of depreciable property, was 1.9% , 1.9% , and 1.9% for 2016 , 2015 , and 2014 , respectively. INCOME TAXES – The Company provides income tax expense for its utility operations in accordance with the regulatory accounting policies of the applicable jurisdictions. The Company’s income tax provision is calculated on a separate return basis. The Connecticut PURA requires the flow-through method of accounting for most state tax temporary differences as well as for certain federal temporary differences. The MPUC requires the flow-through method of accounting for most state temporary differences and normalized accounting for most federal temporary differences. However, in its approvals of the stipulation agreements between Maine Water and the Office of the Public Advocate, issued in 2015, the MPUC has allowed flow-through method of accounting stemming from Maine Water’s adoption of the IRS’ Repair Regulations in all of its divisions. The Company computes deferred tax liabilities for all temporary book-tax differences using the liability method prescribed in FASB ASC 740 “Income Taxes” (“FASB ASC 740”). Under the liability method, deferred income taxes are recognized at currently enacted income tax rates to reflect the tax effect of temporary differences between the financial reporting and tax bases of assets and liabilities. Such temporary differences are the result of provisions in the income tax law that either require or permit certain items to be reported on the income tax return in a different period than they are reported in the financial statements. Deferred tax liabilities that have not been reflected in tax expense due to regulatory treatment are reflected as “Unfunded Future Income Taxes”, and are expected to be included in future years’ rates. The Company believes that deferred income tax assets, net of provisions, will be realized in the future. The majority of unfunded future income taxes, prior to 2013, relate to deferred state income taxes regarding book to tax depreciation differences. Beginning in 2013, basis differences resulting from the repair tax deduction contribute to the change in unfunded income taxes. Deferred Federal and State Income Taxes include amounts that have been provided for accelerated depreciation subsequent to 1981, as required by federal income tax regulations, as well as the basis differences associated with expenditures qualifying for repair tax deduction as clarified by the IRS in regulations issued in 2013. Deferred taxes have also been provided for temporary differences in the recognition of certain expenses for tax and financial statement purposes as allowed by regulatory ratemaking policies. MUNICIPAL TAXES – Municipal taxes are reflected as “Taxes Other Than Income Taxes” and are generally expensed over the twelve-month period beginning on July 1 following the lien date, corresponding with the period in which the municipal services are provided. UNAMORTIZED DEBT ISSUANCE EXPENSE – The issuance costs of long-term debt, including the remaining balance of issuance costs on long-term debt issues that have been refinanced prior to maturity, and related call prem |
