Organization Summary Of Significant Accounting Policies And Recent Developments [Abstract]

(a) Organization - Middlesex Water Company (Middlesex) is the parent company and sole shareholder of Tidewater Utilities, Inc. (Tidewater), Tidewater Environmental Services, Inc. (TESI), Pinelands Water Company (Pinelands Water) and Pinelands Wastewater Company (Pinelands Wastewater) (collectively, Pinelands), Utility Service Affiliates, Inc. (USA), Utility Service Affiliates (Perth Amboy) Inc. (USA-PA) and Twin Lakes Utilities, Inc. (Twin Lakes). Southern Shores Water Company, LLC (Southern Shores) and White Marsh Environmental Systems, Inc. (White Marsh) are wholly-owned subsidiaries of Tidewater.

Middlesex Water Company has operated as a water utility in New Jersey since 1897, in Delaware, through our wholly-owned subsidiary, Tidewater, since 1992 and in Pennsylvania, through our wholly-owned subsidiary, Twin Lakes, since 2009. We are in the business of collecting, treating, distributing and selling water for domestic, commercial, municipal, industrial and fire protection purposes. We also operate New Jersey municipal water, wastewater and storm water systems under contract and provide unregulated water and wastewater services in New Jersey and Delaware through our subsidiaries. We also have an investment in a joint venture, Ridgewood Green RME, LLC, that owns and operates facilities which optimize the production of electricity at the Village of Ridgewood, New Jersey wastewater treatment plant and other municipal facilities. Our rates charged to customers for water and wastewater services, the quality of services we provide and certain other matters are regulated in New Jersey, Delaware and Pennsylvania by the New Jersey Board of Public Utilities (NJBPU), Delaware Public Service Commission (DEPSC) and Pennsylvania Public Utilities Commission (PAPUC), respectively. Our USA, USA-PA and White Marsh subsidiaries are not regulated utilities.

Certain reclassifications have been made to the prior year financial statements to conform with current period presentation. The reclassifications are immaterial to the overall presentation of our consolidated financial statements.

Principles of Consolidation

(b) Principles of Consolidation – The financial statements for Middlesex and its wholly-owned subsidiaries (the Company) are reported on a consolidated basis. All significant intercompany accounts and transactions have been eliminated. Other financial investments in which the Company holds a 50% or less voting interest and cannot exercise control over the operation and policies of the investments are accounted for under the equity method of accounting. Under the equity method of accounting, the Company records its investment interests in Non Utility Assets and its percentage share of the earnings or losses of the investees in Other Income (Expense).

System of Accounts

(c) System of Accounts – Middlesex, Pinelands Water and Pinelands Wastewater maintain their accounts in accordance with the Uniform System of Accounts prescribed by the NJBPU. Tidewater, TESI and Southern Shores maintain their accounts in accordance with DEPSC requirements. Twin Lakes maintains its accounts in accordance with PAPUC requirements.

Regulatory Accounting

(d) Regulatory Accounting - We maintain our books and records in accordance with accounting principles generally accepted in the United States of America. Middlesex and certain of its subsidiaries, which account for 88% of Operating Revenues and 99% of Total Assets, are subject to regulation in the state in which they operate. Those companies are required to maintain their accounts in accordance with regulatory authorities' rules and guidelines, which may differ from other authoritative accounting pronouncements. In those instances, the Company follows the guidance provided in Accounting Standards Codification (ASC) 980, Regulated Operations.

In accordance with ASC 980, Regulated Operations, costs and obligations are deferred if it is probable that these items will be recognized for rate-making purposes in future rates. Accordingly, we have recorded costs and obligations, which will be amortized over various future periods. Any change in the assessment of the probability of rate-making treatment will require us to change the accounting treatment of the deferred item. We have no reason to believe any of the deferred items that are recorded will be treated differently by the regulators in the future. For additional information, see Note 2 – Rate and Regulatory Matters.

Postretirement Benefit Plans

(e) Retirement Benefit Plans - We maintain a noncontributory defined benefit pension plan (Pension Plan) which covers substantially all active employees who were hired prior to April 1, 2007. In addition, the Company maintains an unfunded supplemental plan for its executive officers. The Company has a retirement benefit plan other than pensions (Other Benefits Plan) for substantially all of its retired employees. Employees hired after March 31, 2007 are not eligible to participate in this plan. Coverage includes healthcare and life insurance.

The Company's costs for providing retirement benefits are dependent upon numerous factors, including actual plan experience and assumptions of future experience. Retirement benefit plan obligations and expense are determined based on investment performance, discount rates and various other demographic factors related to the population participating in the Company's retirement benefit plans, all of which can change significantly in future years. For more information on the Company's Retirement Benefit Plans, see Note 7 – Employee Benefit Plans.

Utility Plant

(f) Utility Plant – Utility Plant is stated at original cost as defined for regulatory purposes. Property accounts are charged with the cost of betterments and major replacements of property. Cost includes direct material, labor and indirect charges for pension benefits and payroll taxes. The cost of labor, materials, supervision and other expenses incurred in making repairs and minor replacements and in maintaining the properties is charged to the appropriate expense accounts. At December 31, 2014, there was no event or change in circumstance that would indicate that the carrying amount of any long-lived asset was not recoverable.

Depreciation

(g) Depreciation – Depreciation is computed by each regulated member of the Company utilizing a rate approved by the applicable regulatory authority. The Accumulated Provision for Depreciation is charged with the cost of property retired, less salvage. The following table sets forth the range of depreciation rates for the major utility plant categories used to calculate depreciation for the years ended December 31, 2014, 2013 and 2012. These rates have been approved by the NJBPU, DEPSC or PAPUC:

Source of Supply	1.15% - 3.44%	Transmission and Distribution (T&D):
Pumping	2.87% - 5.39%	T&D – Mains	1.10% - 3.13%
Water Treatment	1.65% - 7.09%	T&D – Services	2.12% - 3.16%
General Plant	2.08% - 17.84%	T&D – Other	1.61% - 4.63%

Non-regulated fixed assets consist primarily of office buildings, furniture and fixtures, and transportation equipment. These assets are recorded at original cost and depreciation is calculated based on the estimated useful lives, ranging from 3 to 40 years.

Preliminary Survey and Investigation (PS&I) Costs

(h) Preliminary Survey and Investigation (PS&I) Costs – In the design of water and wastewater systems that the Company ultimately intends to construct, own and operate certain expenditures are incurred to advance those project activities. These PS&I costs are recorded as deferred charges on the balance sheet because these costs are expected to be recovered through future rates charged to customers as the underlying projects are placed into service as utility plant. If it is subsequently determined that costs for a project recorded as PS&I are not recoverable through rates charged to our customers, the applicable PS&I costs are recorded as Other Expense on the income statement at that time.

Customers' Advances for Construction (CAC)

(i) Customers' Advances for Construction (CAC) – Utility plant and/or cash advances are provided to the Company by customers, real estate developers and builders in order to extend utility service to their properties. These transactions are recorded as CAC. Contractual Refunds of CACs in the form of cash are made by the Company and are based on either additional operating revenues generated from new customers or as new customers are connected to the respective system. After all refunds are made and/or contract terms have expired, any remaining balance is transferred to Contributions in Aid of Construction.

Contributions in Aid of Construction (CIAC) – CIAC include direct non-refundable contributions of utility plant and/or cash and the portion of CAC that becomes non-refundable.

CAC and CIAC are not depreciated in accordance with regulatory requirements. In addition, these amounts reduce the investment base for purposes of setting rates.

Allowance for Funds Used During Construction (AFUDC)

(j) Allowance for Funds Used During Construction (AFUDC) - Middlesex and its regulated subsidiaries capitalize AFUDC, which represents the cost of financing projects during construction. AFUDC is added to the construction costs of individual projects exceeding specific cost and construction period thresholds established for each company and then depreciated along with the rest of the utility plant's costs over its estimated useful life. AFUDC is calculated using each company's weighted cost of debt and equity as approved in their most recent respective regulatory rate order. The AFUDC rates for the years ended December 31, 2014, 2013 and 2012 for Middlesex and Tidewater are as follows:

	2014		2013		2012
Middlesex		7.03%		7.34%		7.34%
Tidewater		7.91%		7.91%		7.91%

Accounts Receivable

(k) Accounts Receivable – We record bad debt expense based on historical write-offs combined with an evaluation of current conditions. The allowance for doubtful accounts was $0.7 million and $0.6 million as of December 31, 2014 and 2013, respectively. For each of the years ended December 31, 2014, 2013, and 2012, bad debt expense was $0.7 million. For the years ended December 31, 2014, 2013, and 2012, write-offs were $0.6 million, $0.9 million and $0.6 million, respectively. Receivables not expected to be received in 2015 are included as non-current assets in Operations Contracts, Developer and Other Receivables.

Revenues

(l) Revenues - Retail customer invoices for regulated utility service are typically comprised of two components; a fixed service charge and a volumetric or consumption charge. Revenues from retail customers, except Tidewater fixed service charges, include amounts billed in arrears on a cycle basis and unbilled amounts estimated from the last meter reading date to the end of the accounting period. The estimated unbilled amounts are determined by utilizing factors which include historical volumetric or consumption usage and current climate and economic conditions. Actual billings may differ from our estimates. Tidewater customers are billed in advance for their fixed service charge and these revenues are recognized as the service is provided to the customer.

Southern Shores is an unmetered system. Customers are billed a fixed service charge in advance at the beginning of each month and revenues are recognized as earned.

Customers in portions of the TESI system are billed a fixed service charge in arrears.

Revenues from the City of Perth Amboy management contract are comprised of fixed and variable fees. Fixed fees, which have been set for the life of the contract, are billed monthly and recorded as earned. Variable fees, which are not significant, are recorded upon approval of the amount by the City of Perth Amboy.

Revenues from USA's operations and maintenance contract for the Borough of Avalon, New Jersey (Avalon) water utility, sewer utility and storm water system are fixed for the life of the contract, are billed monthly and recorded as earned. USA also provides services to Avalon in addition to the base services provided under the operation and maintenance contract. These additional services are recorded as earned and billed upon approval of Avalon.

Deferred Charges and Other Assets

(m) Deferred Charges and Other Assets - Unamortized Debt Expense is amortized over the lives of the related issues. Restricted Cash represents proceeds from loans entered into through state financing programs and is held in trusts. The proceeds are restricted for specific capital expenditures and debt service requirements.

Income Taxes

(n) Income Taxes - Middlesex files a consolidated federal income tax return for the Company and income taxes are allocated based on the separate return method. Investment tax credits have been deferred and are amortized over the estimated useful life of the related property. For more information on income taxes, see Note 3 – Income Taxes.

Statements of Cash Flows

(o) Statements of Cash Flows - For purposes of reporting cash flows, the Company considers all highly liquid investments with original maturity dates of three months or less to be cash equivalents. Cash and cash equivalents represent bank balances and money market funds with investments maturing in less than 90 days.

Use of Estimates

(p) Use of Estimates - Conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts in the financial statements. Actual results could differ from those estimates.

Recent Accounting Pronouncements

(q) Recent Accounting Pronouncements

Revenue Recognition - In May 2014, the Financial Accounting Standards Board issued an update to authoritative guidance related to revenue from contracts with customers. The update replaces most of the existing guidance with a single set of principles for recognizing revenue from contracts with customers. The guidance will be effective for the Company beginning January 1, 2017. Early adoption is not permitted. The new guidance must be applied retrospectively to each prior period presented or retrospectively via a cumulative effect upon the date of initial application. We are currently evaluating the impact that the adoption will have on our consolidated financial statements and related disclosures.

There are no other new adopted or proposed accounting guidance that the Company is aware of that could have a material impact on the Company's financial statements.

Recent Developments

(r) Recent Developments

Middlesex and Tidewater Implement Base Water Rate Increases – In the second quarter of 2014, Middlesex and Tidewater implemented base water rate increases of $4.2 million and $0.8 million, respectively. These increases were necessitated by capital investments made, increased operations and maintenance costs and Middlesex industrial and wholesale customer losses, for which we were given appropriate recognition in the base water rate increases. See Note 2 – Rate and Regulatory Matters below for further discussion of these base water rate increases.

Dover Air Force Base – In April 2014, the DEPSC approved Tidewater's 50-year agreement with the United States Department of Defense for the privatization of the water system of Dover Air Force Base (DAFB) in Dover, Delaware. On October 1, 2014, Tidewater assumed ownership of the DAFB water utility assets and began providing regulated water service to DAFB under Tidewater's DEPSC approved tariff rates.
