Organization, Consolidation and Presentation of Financial Statements [Abstract]
ORGANIZATION AND OPERATIONS	ORGANIZATION AND OPERATIONS California Water Service Group (Company) is a holding company that provides water utility and other related services in California, Washington, New Mexico, and Hawaii through its wholly-owned subsidiaries. California Water Service Company (Cal Water), Washington Water Service Company (Washington Water), New Mexico Water Service Company (New Mexico Water), and Hawaii Water Service Company, Inc. (Hawaii Water) provide regulated utility services under the rules and regulations of their respective state's regulatory commissions (jointly referred to as the Commissions). CWS Utility Services and HWS Utility Services LLC provide non-regulated water utility and utility-related services. The Company operates in one reportable segment, providing water and related utility services. Basis of Presentation The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) and include the Company's accounts and those of its wholly owned subsidiaries. All intercompany transactions and balances have been eliminated from the consolidated financial statements. In the opinion of management, the consolidated financial statements reflect all adjustments that are necessary to provide a fair presentation of the results for the periods covered. The preparation of the Company's consolidated financial statements in accordance 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 consolidated balance sheet dates and the reported amounts of revenues and expenses for the periods presented. These include, but are not limited to, estimates and assumptions used in determining the Company's regulatory asset and liability balances based upon probability assessments of regulatory recovery, utility plant useful lives, revenues earned but not yet billed, asset retirement obligations, allowance for doubtful accounts, pension and other employee benefit plan liabilities, and income tax-related assets and liabilities. Actual results could differ from these estimates.

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Revenue Revenue generally includes monthly cycle customer billings for regulated water and wastewater services at rates authorized by regulatory commissions (plus an estimate for water used between the customer's last meter reading and the end of the accounting period) and billings to certain non-regulated customers at rates authorized by contract with government agencies. The Company's regulated water and related utility services requirements are authorized by the Commissions in the states in which we operate. The revenue requirements are intended to provide the Company a reasonable opportunity to recover its operating costs and earn a return on investments. For metered customers, Cal Water recognizes revenue from rates which are designed and authorized by the CPUC. Under the WRAM, Cal Water records the adopted level of volumetric revenues, which would include recovery of cost of service and a return on investments, as established by the CPUC for metered accounts (adopted volumetric revenues). In addition to volumetric-based revenues, the revenue requirements approved by the CPUC include service charges, flat rate charges, and other items not subject to the WRAM. The adopted volumetric revenue considers the seasonality of consumption of water based upon historical averages. The variance between adopted volumetric revenues and actual billed volumetric revenues for metered accounts is recorded as a component of revenue with an offsetting entry to a regulatory asset or liability balancing account (tracked individually for each Cal Water district) subject to certain criteria under the accounting for regulated operations being met. The variance amount may be positive or negative and represents amounts that will be billed or refunded to customers in the future. Cost-recovery rates are designed to permit full recovery of certain costs allowed to be recovered by the Commissions. Cost-recovery rates such as the MCBA provides for recovery of adopted expense levels for purchased water, purchased power and pump taxes, as established by the CPUC. In addition, cost-recovery rates include recovery of costs related to water conservation programs and certain other operating expenses adopted by the CPUC. Variances (which include the effects of changes in both rates and volumes for the MCBA) between adopted and actual costs are recorded as a component of revenue, as the amount of such variances will be recovered from or refunded to our customers at a later date. Cost-recovery expenses are generally recognized when expenses are incurred with no markup for return or profit. The balances in the WRAM and MCBA assets and liabilities accounts will fluctuate on a monthly basis depending upon the variance between adopted and actual results. The recovery or refund of the WRAM is netted against the MCBA over- or under-recovery for the corresponding district. The recovery or refund of net WRAM and MCBA balances are interest bearing at the current 90 day commercial paper rate. At the end of any calendar year, Cal Water files with the CPUC to refund or collect the balance in the accounts. Undercollected net WRAM and MCBA receivable balances are collected over 12 , 18 or 20 + months. Cal Water defers net WRAM and MCBA operating revenues and associated costs whenever the net receivable balances are estimated to be collected more than 24 months after the respective reporting periods in which it was recognized. The deferred net WRAM and MCBA revenues and associated costs were determined using forecasts of customer consumption trends for future reporting periods and the timing of when the CPUC will authorize Cal Water's filings to recover the undercollected balances. Deferred net WRAM and MCBA revenues and associated costs will be recognized as revenues and costs in future periods when collection is within 24 months of the respective reporting period. Customers meter reads occur on various business days throughout the month. As a result, there are unmetered or unbilled customer usage each month. The estimated unbilled revenue for monthly unmetered customer usage is recorded using the number of unbilled days for that month and average daily customer billing rate for the previous month. The average daily customer billing rate for the previous month fluctuates depending on customer usage. Estimated unbilled revenue is not included in the WRAM until it is billed. Flat rate customers are billed in advance at the beginning of the service period. The revenue is prorated so that the portion of revenue applicable to the current period is included in that period's revenue, with the remaining balance recorded as unearned revenue on the balance sheet and recognized as revenue when earned in the subsequent accounting period. The unearned revenue liability was $1.3 million and $1.5 million as of December 31, 2015 and 2014, respectively. This liability is included in "other accrued liabilities" on our consolidated balance sheets. Non-Regulated Revenue Revenues from non-regulated operations and maintenance agreements are recognized when services have been rendered to companies or municipalities under such agreements. For construction and design services, revenue is generally recognized on the completed contract method, as most projects are completed in less than 3 months . Other non-regulated revenue is recognized when title has transferred to the buyer, or ratably over the term of the lease. Allowance for Doubtful Accounts The Company provides an allowance for doubtful accounts receivable. The allowance is based upon specific identified accounts plus an estimate of uncollectible accounts based upon historical percentages. The balance of customer receivables is net of the allowance for doubtful accounts at December 31, 2015 and 2014 of $0.7 million. The activities in the allowance for doubtful accounts are as follows: 2015 2014 Beginning Balance $ 697 $ 668 Provision for uncollectible accounts 1,674 1,561 Net write off of uncollectible accounts (1,641 ) (1,532 ) Ending Balance $ 730 $ 697 Utility Plant Utility plant is carried at original cost when first constructed or purchased, or at fair value when acquired through acquisition. When depreciable plant is retired, the cost is eliminated from utility plant accounts and such costs are charged against accumulated depreciation. Maintenance of utility plant is charged to operating expenses as incurred. Maintenance projects are not accrued for in advance. Interest is capitalized on plant expenditures during the construction period and amounted to $1.9 million in 2015, $1.5 million in 2014, and $2.0 million in 2013. Intangible assets acquired as part of water systems purchased are recorded at fair value. All other intangibles have been recorded at cost and are amortized over their useful life. The following table represents depreciable plant and equipment as of December 31: 2015 2014 Equipment $ 499,502 $ 487,845 Office buildings and other structures 198,798 194,905 Transmission and distribution plant 1,603,541 1,508,444 Total $ 2,301,841 $ 2,191,194 Depreciation of utility plant for financial statement purposes is computed on a straight-line basis over the assets' estimated useful lives including cost of removal of certain assets as follows: Useful Lives Equipment 5 to 50 years Transmission and distribution plant 40 to 65 years Office Buildings and other structures 50 years The provision for depreciation expressed as a percentage of the aggregate depreciable asset balances was 2.80% in 2015, 2.97% in 2014, and 3.0% 2013. For income tax purposes, as applicable, the Company computes depreciation using the accelerated methods allowed by the respective taxing authorities. Asset Retirement Obligation The Company has a legal obligation to retire wells in accordance with State Water Resources Control Board regulations. In addition, upon decommission of a wastewater plant or lift station certain wastewater infrastructure would need to be retired in accordance with State Water Resources Control Board regulations. An asset retirement cost and corresponding retirement obligation is recorded when a well or waste water infrastructure is placed into service. As of December 31, 2015 and 2014, the retirement obligation is estimated to be $19.5 million and $18.4 million, respectively. The change only impacted the consolidated balance sheet. Cash Equivalents Cash equivalents include highly liquid investments with remaining maturities of three months or less at the time of acquisition. Cash and cash equivalents was $8.8 million and $19.6 million as of December 31, 2015 and December 31, 2014, respectively. Restricted Cash In 2015 restricted cash includes $0.4 million of proceeds collected through a surcharge on certain customers' bills plus interest earned on the proceeds and is used to service California Safe Drinking Water Bond obligations. All restricted cash is included in "taxes, prepaid expenses, and other assets". As of December 31, 2015 and 2014, restricted cash was $0.5 million and $0.9 million, respectively. Regulatory Assets and Liabilities Regulatory assets and liabilities were comprised of the following as of December 31: 2015 2014 Regulatory Assets Pension and retiree group health $ 205,614 $ 245,008 Property-related temporary differences (tax benefits flowed through to customers) 81,522 72,350 Other accrued benefits 27,327 32,959 Interim rates long-term accounts receivable 5,238 10,627 Net WRAM and MCBA long-term accounts receivable 15,410 14,449 Asset retirement obligations, net 14,682 13,863 Tank coating 6,829 — Health care balancing account 3,503 1,075 Other regulatory assets 1,768 — Total Regulatory Assets $ 361,893 $ 390,331 Regulatory Liabilities Future tax benefits due customers $ 29,505 $ 26,114 Conservation program 2,317 2,669 Pension balancing account 792 4,291 Other liabilities 2,650 3,373 Total Regulatory Liabilities $ 35,264 $ 36,447 Short-term regulatory assets and liabilities are excluded from the above table. The short-term regulatory assets for 2015 and 2014 were $35.1 million and $53.2 million, respectively. The short-term regulatory assets were primarily interim rates and net WRAM and MCBA. The short-term portion of regulatory liabilities for 2015 and 2014 were $2.2 million and $6.1 million, respectively. The short-term regulatory liabilities were primarily net WRAM and MCBA liability balances and net refund balances to customers for conservation program from the 2009 general rate case. The Company operates extensively in a regulated business, and as such is subject to the accounting standards for regulated utilities. Utility companies defer costs and credits on the balance sheet as regulatory assets and liabilities when it is probable that those costs and credits will be recognized in the ratemaking process in a period different from the period in which they would have been reflected in income by an unregulated company. Regulatory assets other than WRAM represent deferral of costs that will be recovered in the future and do not earn a return. In determining the probability of costs being recognized in other periods, the Company considers regulatory rules and decisions, past practices, and other facts or circumstances that would indicate if recovery is probable. In the event that a portion of the Company's operations were no longer subject to the accounting standards for regulated utilities, the Company would be required to write off related regulatory assets and liabilities. If a commission determined that a portion of the Company's assets were not recoverable in customer rates, the Company would be required to determine if a disallowance of assets had occurred. If a disallowance had occurred, it would require a write-down in the assets' recorded balance. The Company's pension and postretirement health care benefits regulatory asset is the amount the Company expects to recover from customers in the future for these plans at the end of the calendar year. The property-related temporary differences were primarily due to the difference between book and federal income tax depreciation on utility plant that was placed in service before the regulatory Commissions adopted normalization for rate making purposes. Full normalization requires no flow-through of tax benefits to customers. The regulatory asset will be recovered in rates in future periods as the tax effects of the temporary differences previously flowed-through to customers reverse. Other accrued benefits are accrued benefits for vacation, self-insured workers' compensation, and directors' retirement benefits. The net WRAM and MCBA long-term accounts receivable is the undercollected portion of recorded revenues that are not expected to be collected from customers within 12 months . The asset retirement obligation regulatory asset represents the difference between costs associated with asset retirement obligations and amounts collected in rates. The health care balancing account regulatory asset is for incurred health care costs that exceeded the cost recovery in rates and is recoverable from customers as of December 31, 2015 . Tank coating represents the maintenance costs for tank coating projects that are recoverable from customers as of December 31, 2015. The future tax benefits due to customers represent regulatory liabilities for tax deductions that will be taken and flowed through to customers in the future. Regulatory liabilities also reflect timing differences provided at higher than the current tax rate, which will flow-through to future customers. The conservation program and pension balancing account regulatory liabilities are for cost recovery in rates that exceeded incurred costs and are refundable to customers as of December 31, 2015 . Impairment of Long-Lived Assets, Intangibles and Goodwill The Company's long-lived assets include transmission and distribution plant, equipment, land, buildings, and intangible assets. Long-lived assets, other than land, are depreciated or amortized over their estimated useful lives, and are reviewed for impairment whenever changes in circumstances indicate the carrying value of the assets may not be recoverable. Such circumstances would include items such as a significant decrease in the market value of a long-lived asset, a significant adverse change in the manner in which the asset is being used or planned to be used or in its physical condition, or a history of operating or cash flow losses associated with the uses of the asset. In addition, changes in the expected useful life of these long-lived assets may also be an impairment indicator. When such events or changes occur, we estimate the fair value of the asset from future cash flows expected to result from the use and, if applicable, the eventual disposition of the assets, and compare that to the carrying value of the asset. If the carrying value is greater than the fair value,an impairment loss is recognized equal to the amount by which the asset's carrying value exceeds its fair value. The key variables that must be estimated include assumptions regarding sales volume, rates, operating costs, labor and other benefit costs, capital additions, assumed discount rates and other economic factors. These variables require significant management judgment and include inherent uncertainties since they are forecasting future events. A variation in the assumptions used could lead to a different conclusion regarding the realizability of an asset and, thus could have a significant effect on the consolidated financial statements. Goodwill is measured as the excess of the cost of an acquisition over the sum of the amounts assigned to identifiable assets acquired less liabilities assumed. Goodwill is not amortized but instead is reviewed annually at November 30 th for impairment or more frequently if impairment indicators arise. The impairment test is performed at the reporting unit level using a two- step, fair-value based approach. The first step determines the fair value of the reporting unit and compares it to the reporting unit's carrying value. If the fair value of the reporting unit is less than its carrying amount, a second step is performed to measure the amount of impairment loss, if any. The second step allocates the fair value of the reporting unit to the Company's tangible and intangible assets and liabilities. This derives an implied fair value for the reporting unit's goodwill. If the carrying amount of the reporting unit's goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized equal to the excess. Long-Term Debt Premium, Discount and Expense The premiums, discounts, and issuance expenses on long-term debt are amortized over the original lives of the related debt on a straight-line basis which approximates the effective interest method. Premiums paid on the early redemption of certain debt and the unamortized original issuance discount and expense are amortized over the life of new debt issued in conjunction with the early redemption. Amortization expense included in interest expense was $0.8 million, $0.8 million, and $1.1 million for 2015, 2014, and 2013, respectively. Advances for Construction Advances for construction consist of payments received from developers for installation of water production and distribution facilities to serve new developments. Advances are excluded from rate base for rate setting purposes. Annual refunds are made to developers without interest. Advances of $180.2 million, and $182.3 million at December 31, 2015 and 2014, respectively, will be refunded primarily over a 40 -year period in equal annual amounts. Estimated refunds of advances for the succeeding 5 years are approximately $7.9 million in 2016, $7.7 million in 2017, $7.7 million in 2018, $7.6 million in 2019, and $7.6 million in 2020. Contributions in Aid of Construction Contributions in aid of construction represent payments received from developers, primarily for fire protection purposes, which are not subject to refunds. Facilities funded by contributions are included in utility plant, but excluded from rate base. Depreciation related to assets acquired from contributions is charged to the Contributions in Aid of Construction account. Income Taxes The Company accounts for income taxes using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Measurement of the deferred tax assets and liabilities is at enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the period that includes the enactment date. The Company evaluates the need for a valuation allowance on deferred tax assets based on historical taxable income and projected taxable income for future tax years. Historically the Commissions reduced revenue requirements for the tax effects of certain originating temporary differences and allowed recovery of these tax costs as the related temporary differences reverse. The Commissions have granted the Company rate increases to reflect the normalization of the tax benefits of the federal accelerated methods and available Investment Tax Credits (ITC) for all assets placed in service after 1980. ITCs are deferred and amortized over the lives of the related properties for book purposes. The CPUC granted flow-through for state taxes. Advances for Construction and Contributions in Aid of Construction received from developers subsequent to 1986 were taxable for federal income tax purposes and subsequent to 1991 were subject to California income tax. In 1996, the federal tax law, and in 1997, the California tax law, changed and only deposits for new services were taxable. In late 2000, federal regulations were further modified to exclude contributions of fire services from taxable income. The accounting standards for accounting for uncertainty in income taxes allows the inclusion of interest and penalties related to uncertain tax positions as a component of income taxes. See note 10 "Income Taxes". Workers' Compensation For workers' compensation, the Company estimates the liability associated with claims submitted and claims not yet submitted based on historical data. Expenses for workers compensation insurance are included in rates on a pay-as- you-go basis. Therefore, a corresponding regulatory asset has been recorded. Earnings per Share The computations of basic and diluted earnings per share are noted below. Basic earnings per share are computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share reflect the potential dilution that could occur if securities or other contracts were exercised or converted into common stock. Restricted Stock Awards (RSAs) are included in the common shares outstanding because the shares have all the same voting and dividend rights as issued and unrestricted common stock. The Company did not grant any Stock Appreciation Rights (SARs) in 2015, 2014, and 2013. SARs outstanding were 64,500 shares as of December 31, 2015, 186,356 shares as of December 31, 2014, and 283,856 shares as of December 31, 2013. All SARs were dilutive in 2015, 2014 and 2013. The dilutive effect is shown in the table below: 2015 2014 2013 (In thousands, Net income as reported and available to common stockholders $ 45,017 $ 56,738 $ 47,254 Weighted average common shares, basic 47,865 47,791 46,384 Dilutive common stock equivalents (treasury method) 15 38 33 Shares used for dilutive calculation 47,880 47,829 46,417 Earnings per share—basic $ 0.94 $ 1.19 $ 1.02 Earnings per share—diluted $ 0.94 $ 1.19 $ 1.02 Stock-based Compensation Stock-based compensation cost is measured at the grant date based on the fair value of the award. The Company recognizes compensation expense on a straight-line basis over the requisite service period, which is the vesting period. Comprehensive Income or Loss Comprehensive income for all periods presented was the same as net income. Accumulated Other Comprehensive Income The Company did not have any accumulated other comprehensive income or loss transactions for 2015 and 2014. New Accounting Standards On November 10, 2015 the Financial Accounting Standards Board (FASB) issued an accounting standards update (ASU) 2015-17, Balance Sheet Classification of Deferred Taxes . This update requires the presentation of deferred tax assets and liabilities as noncurrent assets and liabilities in the balance sheet. ASU 2015-17 is effective for annual reporting periods beginning after December 15, 2016 and early adoption is permitted. In 2015, the Company implemented ASU 2015-17 as of the year ended December 31, 2015 on a prospective basis and the prior periods have not been retrospectively adjusted. On May 28, 2014 the FASB issued an ASU 2014-9, Revenue from Contracts with Customers . This update creates a single, principles based framework for revenue recognition and is based on principles that govern the recognition of revenue at an amount an entity expects to be entitled when goods or services are transferred to customers. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, deferring the effective date of this amendment for public companies by one year to January 1, 2018, with early adoption permitted as of the original effective date of January 1, 2017. The Company is currently evaluating the impact of adopting the new revenue standard on its consolidated financial statements and related disclosures.

SHORT-TERM BORROWINGS	SHORT-TERM BORROWINGS On March 10, 2015, the Company and Cal Water entered into Syndicated Credit Agreements, which provide for unsecured revolving credit facilities of up to an initial aggregate amount of $450.0 million for a term of 5 years . The Syndicated Credit Facilities amend, expand, and replace the Company’s and its subsidiaries’ existing credit facilities originally entered into on June 29, 2011. The new credit facilities extended the terms until March 10, 2020, and increased the Company’s unsecured revolving line of credit. The Company and subsidiaries that it designates may borrow up to $150.0 million under the Company’s revolving credit facility. Cal Water may borrow up to $300.0 million under its revolving credit facility; however, all borrowings need to be repaid within 12 months unless otherwise authorized by the CPUC. The credit facilities may each be expanded by up to $50.0 million subject to certain conditions. The proceeds from the revolving credit facilities may be used for working capital purposes, including the short-term financing of capital projects. The base loan rate may vary from LIBOR plus 72.5 basis points to LIBOR plus 95 basis points , depending on the Company’s total debt ratio. Likewise, the unused commitment fee may vary from 8 basis points to 12.5 basis points based on the same ratio. Both short-term unsecured credit agreements contain affirmative and negative covenants and events of default customary for credit facilities of this type including, among other things, limitations and prohibitions relating to additional indebtedness, liens, mergers, and asset sales. Also, these unsecured credit agreements contain financial covenants governing the Company and its subsidiaries' consolidated total debt ratio and interest coverage ratio. As of December 31, 2015 and December 31, 2014, the outstanding borrowings on the Company lines of credit were $33.6 million and $61.7 million, respectively.

These tax regulations allowed the Company to take deductions of linear asset costs previously capitalized for book and tax purposes for the repair and maintenance within the guidance of the final tangible property regulations. The Company's 2015, 2014 and 2013 federal qualified repairs and maintenance deductions totaled $60.0 million , $45.2 million , and $94.8 million . The total federal NOL carry-forward was $43.9 million and the state NOL carry-forward was $58.2 million as of December 31, 2015 net of any unrecognized tax benefit. Management has concluded that the NOL carry-forward amounts are more likely than not to be recovered and therefore require no valuation allowance. The NOL carry-forward will begin to expire in 2032. As of December 31, 2015, the California Enterprise Zone (EZ) credit was $3.1 million net of federal tax benefit for qualified property purchased before January 1, 2014, and placed in service before January 1, 2015. The Company filed amended state income tax returns for tax years 2008, 2009, 2010, and 2011 to claim the benefit of the EZ credits. The Company has carry-forward California EZ credits of $2.3 million net of any unrecognized tax benefit. Unused State of California EZ credits can carry-forward until 2024 . On December 19, 2014, President Obama signed into law Tax Increase Prevention Act of 2014, which, among other provisions, extended the 50 -percent special allowance for depreciation ("bonus depreciation") for qualified property through the end of 2014. On December 18, 2015, Congress passed a tax extenders package, Protecting Americans from Tax Hikes (PATH) Act of 2015, which extends bonus depreciation. The provision extends bonus depreciation for property acquired and placed in service during 2015 through 2019. The federal income tax deduction was estimated at $6.0 million in 2015 and $21.4 million in 2014. As of December 31, 2015 and 2014 the deferred tax liability for bonus depreciation was $2.1 million and $7.5 million , respectively. The difference between the total income tax expense and computed tax expense was reconciled in the table below: 2015 2014 2013 Computed "expected" tax expense $ 24,607 $ 29,649 $ 23,708 Increase (reduction) in taxes due to: State income taxes net of federal tax benefit 4,043 4,871 3,895 Effect of regulatory treatment of fixed asset differences (3,450 ) (5,541 ) (4,112 ) State tax credits — — (2,465 ) Investment tax credits (74 ) (74 ) (74 ) Other 163 (933 ) (483 ) Total income tax $ 25,289 $ 27,972 $ 20,469 The effect of regulatory treatment of fixed asset differences includes 2015 estimated repair and maintenance deduction and asset related flow through items. The tax effects of differences that give rise to significant portions of the deferred tax assets and deferred tax liabilities at December 31, 2015 and 2014 are presented in the following table: 2015 2014 Deferred tax assets: Developer deposits for extension agreements and contributions in aid of construction $ 45,670 $ 44,775 Net operating loss carryforward and tax credits 15,042 19,866 Other 11,263 8,904 Total deferred tax assets 71,975 73,545 Deferred tax liabilities: Property related basis and depreciation differences 309,088 272,958 WRAM/MCBA and interim rates balancing accounts 23,894 30,871 Other 3,890 4,308 Total deferred tax liabilities 336,872 308,137 Net deferred tax liabilities $ 264,897 $ 234,592 In 2015, the Company implemented ASU 2015-17 as of the year ended December 31, 2015 on a prospective basis and the prior periods have not been retrospectively adjusted. A valuation allowance was not required at December 31, 2015 and 2014. Based on historical taxable income and future taxable income projections over the period in which the deferred assets are deductible, management believes it is more likely than not that the Company will realize the benefits of the deductible differences. The following table reconciles the changes in unrecognized tax benefits: December 31, 2015 December 31, 2014 December 31, 2013 Balance at beginning of year $ 7,916 $ 612 $ — Additions for tax positions taken during prior year — — — Additions for tax positions taken during current year 2,382 7,304 612 Reductions for tax positions taken during a prior year — — — Lapse of statute of limitations — — — Balance at end of year $ 10,298 $ 7,916 $ 612 The Company does not expect a material change in its unrecognized tax benefits within the next 12 months. The component of unrecognized tax benefits that, if recognized, would affect the effective tax rate at December 31, 2015, 2014, and 2013 for the Company was $2.1 million , $1.6 million , and $0.4 million with the remaining balance representing the potential deferral of taxes to later years. The Company federal income tax years subject to an examination are 2014, 2013 and 2012 and the state income tax years subject to an examination are 2014, 2013, 2012 and 2011. The State of California Franchise Tax Board is presently auditing the Company's 2008 through 2011 EZ credit filings which were amended by the Company in 2013. It is uncertain when the State audits will be completed.

Compensation and Retirement Disclosure [Abstract]
EMPLOYEE BENEFIT PLANS	EMPLOYEE BENEFIT PLANS Savings Plan The Company sponsors a 401(k) qualified defined contribution savings plan that allows participants to contribute up to 20% of pre-tax compensation. Effective January 1, 2010, the Company matches 75 cents for each dollar contributed by the employee up to a maximum Company match of 6.0% of base salary. Company contributions were $5.0 million, $4.5 million, and $4.3 million, for the years 2015, 2014, and 2013, respectively. Pension Plans The Company provides a qualified, defined-benefit, non-contributory pension plan for substantially all employees. The accumulated benefit obligations of the pension plan are $392.7 million and $390.6 million as of December 31, 2015 and 2014, respectively. The fair value of pension plan assets was $328.6 million and $306.3 million as of December 31, 2015 and 2014, respectively. Prior to 2010, pension payment obligations were generally funded by the purchase of an annuity from a life insurance company. Beginning in 2010, the pension plan trust pays monthly benefits to retirees, rather than the purchase of an annuity. Expected payments to be made are $10.3 million in 2016, $11.7 million in 2017, $13.3 million in 2018, $14.8 million in 2019, and $16.4 million in 2020. The aggregate benefits expected to be paid in the 5 years 2021 through 2025 are $107.3 million. The expected benefit payments are based upon the same assumptions used to measure the Company's benefit obligation at December 31, 2015, and include estimated future employee service. The Company also maintains an unfunded, non-qualified, supplemental executive retirement plan. The unfunded supplemental executive retirement plan accumulated benefit obligations were $40.4 million and $40.2 million as of December 31, 2015 and 2014, respectively. Benefit payments under the supplemental executive retirement plan are paid currently and are included in the preceding paragraph. The costs of the pension and retirement plans are charged to expense and utility plant. The Company makes annual contributions to fund the amounts accrued for pension cost. Other Postretirement Plan The Company provides substantially all active, permanent employees with medical, dental, and vision benefits through a self-insured plan. Employees retiring at or after age 58 , along with their spouses and dependents, continue participation in the plan by payment of a premium. Plan assets are invested in mutual funds, short-term money market instruments and commercial paper based upon a similar asset mix to the pension plan. Retired employees are also provided with a five thousand dollar life insurance benefit. The Company records the costs of postretirement benefits other than pension (PBOP) during the employees' years of active service. Postretirement benefit expense recorded in 2015, 2014, and 2013, was $15.1 million, $8.4 million, and $9.0 million, respectively. The remaining net periodic benefit cost was $4.8 million at December 31, 2015, and is being recovered through future customer rates and is recorded as a regulatory asset. The expected benefit payments, net of retiree premiums and Medicare Part D subsidies, are $2.5 million in 2016, $2.8 million in 2017, $3.2 million in 2018, $3.5 million in 2019, and $3.8 million in 2020. The aggregate benefits expected to be paid in the 5 years 2021 through 2025 are $23.4 million. The Medicare Part D subsidies are $0.3 million in 2016, $0.4 million in 2017, $0.4 million in 2018, $0.5 million in 2019, and $0.5 million in 2020. Benefit Plan Assets The Company actively manages pensions and PBOP trust (Plan) assets. The Company's investment objectives are: • Maximize the return on the assets, commensurate with the risk that the Company deems appropriate to, meet the obligations of the Plans, minimize the volatility of the pension expense, and account for contingencies; • Generate a rate of return for the total portfolio that equals or exceeds the actuarial investment rate assumption; Additionally, the rate of return of the total fund is measured periodically against a index comprised of 35% of the Standard & Poor's Index, 15% of the Russell 2000 Index, 10% of the MSCI EAFE Index, and 40% of the Lehman Aggregate Bond Index. The special index is consistent with the Company's rate of return objective and indicates the Company's long-term asset allocation objective. The Company applies a risk management framework for managing the risks associated with employee benefit plan trust assets. The guiding principles of this risk management framework are the clear articulation of roles and responsibilities, appropriate delegation of authority, and proper accountability and documentation. Trust investment policies and investment manager guidelines include provisions to ensure prudent diversification, manage risk through appropriate use of physical direct asset holdings and derivative securities, and identify permitted and prohibited investments. The Company's target asset allocation percentages for major categories of the pension plan are reflected in the table below: Minimum Exposure Target Maximum Exposure Fixed Income 35 % 40 % 45 % Total Domestic Equity 40 % 50 % 60 % Small Cap Stocks 10 % 15 % 20 % Large Cap Stocks 30 % 35 % 45 % Non-U.S. Equities 5 % 10 % 15 % The fixed income category includes money market funds, short-term bond funds, and cash. The majority of fixed income investments range in maturities from less than 1 to 5 years . The Company's target allocation percentages for the PBOP trust is similar to the pension plan except for a larger allocation in fixed income investments and a lower allocation in equity investments. We use the following criteria to select investment funds: • Fund past performance; • Fund meets criteria of Employee Retirements Income Security Act (ERISA); • Timeliness and completeness of fund communications and reporting to investors; • Stability of fund management company; • Fund management fees; and • Administrative costs incurred by the Plan. Plan Fair Value Measurements The fair value measurements standard establishes a framework for measuring fair value. That framework provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (level 1 measurements) and the lowest priority to unobservable inputs (level 3 measurements). The three levels of the fair value hierarchy under the standard are described below: Level 1 —Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets that the Plan has the ability to access. Level 2 —Inputs to the valuation methodology include: • Quoted market prices for similar assets or liabilities in active markets; • Quoted prices for identical or similar assets or liabilities in inactive markets; • Inputs other than quoted prices that are observable for the asset or liability; and • Inputs that are derived principally from or corroborated by observable market data by correlation or other means. If the asset or liability has a specified (contractual) term, the level 2 input must be observable for substantially the full term of the asset or liability. Level 3 —Inputs to the valuation methodology are unobservable and significant to the fair value measurement. All Plan investments are level one investments in mutual funds and are valued at the net asset value (NAV) of the shares held at December 31, 2015 and 2014: Pension Benefits Other Benefits 2015 % 2014 % 2015 % 2014 % Fixed Income $ 132,736 40 % $ 119,814 39 % $ 48,325 66 % $ 36,313 61 % Domestic Equity: Small Cap Stocks 47,014 14 % 47,798 16 % — — Domestic Equity: Large Cap Stocks 116,306 36 % 108,163 35 % 24,561 34 % 23,528 39 % Non U.S. Equities 32,578 10 % 30,569 10 % — — % — — % Total Plan Assets $ 328,634 100 % $ 306,344 100 % $ 72,886 100 % $ 59,841 100 % The pension benefits fixed income category includes $11.1 million and $3.6 million of money market fund investments as of December 31, 2015 and 2014, respectively. The other benefits fixed income category includes $32.7 million and $22.1 million of money market fund investments as of December 31, 2015 and 2014. Changes in Plan Assets, Benefits Obligations, and Funded Status The following table reconciles the funded status of the plans with the accrued pension liability and the net postretirement benefit liability as of December 31, 2015 and 2014: Pension Benefits Other Benefits 2015 2014 2015 2014 Change in projected benefit obligation: Beginning of year $ 502,585 $ 383,198 $ 135,233 $ 79,066 Service cost 21,306 15,964 8,476 5,205 Interest cost 20,104 18,920 5,654 4,455 Assumption change (50,393 ) 89,692 (12,580 ) 37,021 Experience loss 16,779 2,158 1,794 11,020 Benefits paid, net of retiree premiums (8,502 ) (7,347 ) (1,841 ) (1,534 ) End of year $ 501,879 $ 502,585 $ 136,736 $ 135,233 Change in plan assets: Fair value of plan assets at beginning of year $ 306,344 $ 266,178 $ 59,841 $ 49,939 Actual return on plan assets (2,101 ) 19,374 (919 ) 2,376 Employer contributions 32,893 28,139 15,805 9,060 Retiree contributions and Medicare part D subsidies — — 1,666 1,535 Benefits paid (8,502 ) (7,347 ) (3,507 ) (3,069 ) Fair value of plan assets at end of year $ 328,634 $ 306,344 $ 72,886 $ 59,841 Funded status(1) $ (173,245 ) $ (196,241 ) $ (63,850 ) $ (75,392 ) Unrecognized actuarial loss 108,798 138,609 59,440 70,279 Unrecognized prior service cost 32,341 30,390 250 295 Net amount recognized $ (32,106 ) $ (27,242 ) $ (4,160 ) $ (4,818 ) _______________________________________________________________________________ (1) The short-term portion of the pension benefits was $1.8 million as of December 31, 2015 and 2014. Amounts recognized on the balance sheet consist of: Pension Benefits Other Benefits 2015 2014 2015 2014 (Accrued) benefit costs $ — $ — $ (4,785 ) $ (5,476 ) Accrued benefit liability (173,245 ) (196,241 ) (63,850 ) (75,392 ) Regulatory asset 141,139 168,999 64,475 76,050 Net amount recognized $ (32,106 ) $ (27,242 ) $ (4,160 ) $ (4,818 ) Valuation Assumptions Below are the actuarial assumptions used in determining the benefit obligation for the benefit plans: Pension Benefits Other Benefits 2015 2014 2015 2014 Weighted average assumptions as of December 31: Discount rate 4.40 % 4.00 % 4.40 % 4.00 % Long-term rate of return on plan assets 6.50 % 6.50 % 5.50 % 5.50 % Rate of compensation increases 3.25 % 3.25 % — — Cost of living adjustment 2.50 % 2.50 % — — The discount rate was derived from the Citigroup Pension Discount Curve using the expected payouts for the plan. The long-term rate of return assumption is the expected rate of return on a balanced portfolio invested roughly 60% in equities and 40% in fixed income securities. Returns on equity investments were estimated based on estimates of dividend yield and real earnings added to a 2.50% long-term inflation rate. For the pension and other benefit plans, the assumed returns were 7.99% for domestic equities and 8.64% for foreign equities. Returns on fixed-income investments were projected based on investment maturities and credit spreads added to a 2.50% long-term inflation rate. For the pension and other benefit plans, the assumed returns were 5.02% for fixed income investments and 3.30% for short-term cash investments. The average return for the pension and other benefit plans for the last 5 and 10 years was 7.00% and 5.70% , respectively. The Company is using a long-term rate of return of 6.50% for the pension plan and 5.50% for the other benefit plan, which is between the 25th and 75th percentile of expected results. In 2015, the Company used the Society of Actuaries 2014 Mortality Tables Report (RP-2014) and Mortality Improvement Scale (MP-2015 with modifications) for measuring retirement plan obligations. The RP-2014 mortality table and improvement scale extended the assumed life expectancy of plan participants which resulted in an increase in the Company's accrued benefit obligation as of December 31, 2015 and 2014. Components of Net Periodic Benefit Cost Net periodic benefit costs for the pension and other postretirement plans for the years ended December 31, 2015, 2014, and 2013 included the following components: Pension Plan Other Benefits 2015 2014 2013 2015 2014 2013 Service cost $ 21,306 $ 15,964 $ 17,780 $ 8,476 $ 5,205 $ 5,374 Interest cost 20,104 18,920 16,354 5,654 4,455 3,556 Expected return on plan assets (19,138 ) (16,599 ) (14,252 ) (3,519 ) (3,119 ) (2,394 ) Net amortization and deferral 15,485 10,074 15,302 4,536 1,861 2,441 Net periodic benefit cost $ 37,757 $ 28,359 $ 35,184 $ 15,147 $ 8,402 $ 8,977 Below are the actuarial assumptions used in determining the net periodic benefit costs for the benefit plans, which uses the end of the prior year as the measurement date: Pension Benefits Other Benefits 2015 2014 2015 2014 Weighted average assumptions as of December 31: Discount rate 4.00 % 5.00 % 4.00 % 5.00 % Long-term rate of return on plan assets 6.50 % 6.75 % 5.50 % 6.00 % Rate of compensation increases 3.25 % 4.00 % — — The health care cost trend rate assumption has a significant effect on the amounts reported. For 2015 measurement purposes, the Company assumed a 8.0% annual rate of increase in the per capita cost of covered benefits with the rate decreasing to 5.5% by 2018, then gradually grading down to 4.4% over the next 50 years . A 1-percentage point change in assumed health care cost trends is estimated to have the following effect: 1-Percentage Point Increase 1-Percentage Point (Decrease) Effect on total service and interest costs $ 4,668 $ (3,303 ) Effect on accumulated postretirement benefit obligation $ 34,852 $ (25,903 ) The Company intends to make annual contributions that meet the funding requirements of ERISA. The Company estimates in 2016 that the annual contribution to the pension plans will be $31.7 million and the annual contribution to the other postretirement plan will be $12.7 million.

STOCK-BASED COMPENSATION PLANS	STOCK-BASED COMPENSATION PLANS The Company has one stockholder-approved stock-based compensation plan. Equity Incentive Plan The Company's equity incentive plan was approved by stockholders on April 27, 2005 and May 20, 2014. The Company is authorized to issue awards up to 2,000,000 shares of common stock. During 2015 and 2014, the Company granted annual Restricted Stock Awards (RSAs) of 61,862 shares and 60,467 shares, respectively, of common stock to officers and directors of the Company. In 2015, 18,452 RSA shares were canceled and 10,544 RSA shares were canceled in 2014. Employee RSAs granted in 2015 and 2014 vest over 36 months with the first year cliff vesting. Director RSAs generally vest at the end of 12 months . During 2015 and 2014, the shares granted were valued at $24.27 and $23.62 per share, respectively, based upon the fair market value of the Company's common stock on the date of grant. The Company granted performance-based Restricted Stock Unit Awards (RSUs) of 38,983 shares, 39,232 shares and 50,267 shares of common stock to officers in 2015, 2014 and 2013. Each award reflects a target number of shares that may be issued to the award recipient. The awards may be earned upon the completion of a 3 -year performance period ending on December 31, 2015 for the 2013 RSUs, December 31, 2016 for the 2014 RSUs, and December 31, 2017 for the 2015 RSUs . Whether RSUs are earned at the end of the performance period will be determined based on the achievement of certain performance objectives set by the Board of Director Compensation Committee in connection with the issuance of the RSUs. The performance objectives are based on the Company's business plan covering the performance period. The performance objectives include achieving the budgeted return on equity, budgeted investment in utility plant, customer service standards, employee safety standards and water quality standards. Depending on the results achieved during the 3 -year performance period, the actual number of shares that a grant recipient receives at the end of the performance period may range from 0% to 200% of the target shares granted, provided that the grantee is continuously employed by the Company through the vesting date. If prior to the vesting date employment is terminated by reason of death, disability or normal retirement, then a pro rata portion of this award will vest. RSUs are not included in diluted shares for financial reporting until earned. The RSUs are recognized as expense ratably over the 3 year performance period using a fair market value of $24.28 per share for the 2015 RSUs, $23.61 per share for the 2014 RSUs, and $20.62 per share for the 2013 RSUs and an estimate of RSUs earned during the performance period. The Company has recorded compensation costs for the RSAs and RSUs which are included in administrative and general operating expenses in the amount of $2.9 million, $2.2 million, and $1.8 million for 2015, 2014 and 2013, respectively.

Fair Value Disclosures [Abstract]
FAIR VALUE OF FINANCIAL INSTRUMENTS	FAIR VALUE OF FINANCIAL INSTRUMENTS The accounting guidance for fair value measurements and disclosures provides a single definition of fair value and requires certain disclosures about assets and liabilities measured at fair value. A hierarchal framework for disclosing the observability of the inputs utilized in measuring assets and liabilities at fair value is established by this guidance. The three levels in the hierarchy are as follows: Level 1 —Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets that the Plan has the ability to access. Level 2 —Inputs to the valuation methodology include: • Quoted market prices for similar assets or liabilities in active markets; • Quoted prices for identical or similar assets or liabilities in inactive markets; • Inputs other than quoted prices that are observable for the asset or liability; and • Inputs that are derived principally from or corroborated by observable market data by correlation or other means. If the asset or liability has a specified (contractual) term, the level 2 input must be observable for substantially the full term of the asset or liability. Level 3 —Inputs to the valuation methodology are unobservable and significant to the fair value measurement. Specific valuation methods include the following: Accounts receivable and accounts payable carrying amounts approximated the fair value because of the short-term maturity of the instruments. Long-term debt fair values were estimated using the published quoted market price, if available, or the discounted cash flow analysis, based on the current rates available using a risk-free rate (a U.S. Treasury securities yield curve) plus a risk premium of 1.35% . Advances for construction fair values were estimated using broker quotes from companies that frequently purchase these investments.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Commitments The Company leases offices, equipment and other facilities, two water systems from cities, and has long-term commitments to purchase water from water wholesalers. The commitments are noted in the table below. Facility Leases System Lease Water Contracts Capital Lease Obligations 2016 $ 910 $ 845 $ 23,398 $ 1,109 2017 622 845 23,426 1,109 2018 1,334 493 23,428 1,016 2019 404 — 23,427 1,248 2020 298 — 23,428 940 Thereafter 2,828 — 448,307 5,405 Company Facility leases include office and other facilities in many of its operating districts. The total paid and charged to operations for such leases was $1.1 million in 2015, $0.9 million in 2014, and $1.1 million in 2013. The system lease is a 15 -year lease with the City of Commerce. The lease includes an annual lease payment of $0.8 million per year plus a cost savings sharing arrangement. The Company has a long-term contract with the Santa Clara Valley Water District that requires the Company to purchase minimum annual water quantities. Purchases are priced at the districts then-current wholesale water rate. The Company operates to purchase sufficient water to equal or exceed the minimum quantities under the contract. The total paid to Santa Clara Valley Water District was $6.3 million in 2015, $5.5 million in 2014, and $7.4 million in 2013. The Company also has a water supply contract with Stockton East Water District (SEWD) that requires a fixed, annual payment. Each year, the fixed annual payment is adjusted for changes to SEWD's costs. Because of the fixed annual price arrangement, the Company operates to receive as much water as possible from SEWD in order to minimize the cost of operating Company-owned wells used to supplement SEWD deliveries. The total paid under the contract was $9.8 million in 2015, $8.7 million in 2014, and $10.0 million in 2013. Estimated annual contractual obligations in the table above are based on the same payment levels as 2015. Future increased costs by SEWD are expected to be offset by a decline in the allocation of costs to the Company, as other customers of SEWD are expected to receive a larger allocation based upon growth of their service areas. On September 21, 2005, the Company entered into an agreement with Kern County Water Agency (Agency) to obtain treated water for the Company's operations. The term of the agreement is to January 1, 2035, or until the repayment of the Agency's bonds (described hereafter) occurs. Under the terms of the agreement, the Company is obligated to purchase approximately 19,500 acre feet of treated water in 2015 and an incrementally higher volume of water for each subsequent year until 2017, when the Company is obligated to purchase 20,500 acre feet of treated water per year. The Company is obligated to pay the Capital Facilities Charge and the Treated Water Charge regardless of whether it can use the water in its operation, and is obligated for these charges even if the Agency cannot produce an adequate amount to supply the 20,500 acre feet in the year. This agreement supersedes a prior agreement with Kern County Water Agency for the supply of 11,500 acre feet of water per year. Three other parties, including the City of Bakersfield, are also obligated to purchase a total of 32,500 acre feet per year under separate agreements with the Agency. Further, the Agency has the right to proportionally reduce the water supply provided to all of the participants if it cannot produce adequate supplies. The participation of all parties in the transaction for expansion of the Agency's facilities, including the Water Purification Plant, purchase of the water, and payment of interest and principal on the bonds being issued by the Agency to finance the transaction is required as a condition to the obligation of the Agency to proceed with expansion of the Agency's facilities. If any of the other parties does not use its allocation, that party is obligated to pay its contracted amount. The Agency has issued bonds to fund the project and uses the payments of the Capital Facilities Charges by the Company and the other contracted parties to meet the Agency's obligations to pay interest and repay principal on the bonds. If any of the parties were to default on making payments of the Capital Facilities Charge, then the other parties are obligated to pay for the defaulting party's share on a pro-rata basis. If there is a payment default by a party and the remaining parties have to make payments, they are also entitled to a pro-rata share of the defaulting party's water allocation. The Company expects to use all its entitled water in its operations every year. In addition, if the Company were to pay for and receive additional amounts of water due to a default of another participating party; the Company believes it could use this additional water in its operations without incurring substantial incremental cost increases. If additional treated water is available, all parties have an option to purchase this additional treated water, subject to the Agency's right to allocate the water among the parties. The total obligation of all parties, excluding the Company, is approximately $82.4 million to the Agency. Based on the credit worthiness of the other participants, which are government entities, it is believed to be highly unlikely that the Company would be required to assume any other parties' obligations under the contract due to their default. In the event of default by a party, the Company would receive entitlement to the additional water for assuming any obligation. We pay a capital facilities charge and charges related to treated water that together total $7.6 million annually, which equates to $373 dollars per acre foot. Total treated water charge for 2015 was $2.8 million. As treated water is being delivered, we will also be obligated for our portion of the operating costs; that portion is currently estimated to be $22 dollars per acre foot. The actual amount will vary due to variations from estimates, inflation, and other changes in the cost structure. Our overall estimated cost of $373 dollars per acre foot is less than the estimated cost of procuring untreated water (assuming water rights could be obtained) and then providing treatment. There are three capital leases; the most significant was the City of Hawthorne water system. In 2011, we entered into a 15 -year capital lease agreement to operate the City of Hawthorne water system. The system, which is located near the Hermosa Redondo district, serves about half of Hawthorne's population. The agreement required us to make an up-front $8.1 million lease deposit to the city that is being amortized over the lease term. Additionally, annual lease payments of $0.9 million are made to the city and shall be increased or decreased each year on July 1, by the same percentage that the rates charged to customers served by the water system increased or decreased, exclusive of pass-through increases or decreases in the cost of water, power, and city-imposed fees, compared to the rates in effect on July 1 of the prior year, provided, that in no event will the annual lease payment be less than $0.9 million. Under the lease we are responsible for all aspects of system operation and capital improvements, although title to the system and system improvements reside with the city. In exchange, we receive all revenue from the water system, which was $8.0 million, $7.8 million, and $7.7 million in 2015, 2014, and 2013, respectively. At the end of the lease, the city is required to reimburse us for the unamortized value of capital improvements made during the term of the lease. The annual payments were $0.9 million in 2015, 2014, and 2013. The capital lease asset was $8.1 million as of December 31, 2015. Contingencies Groundwater Contamination The Company has undertaken litigation against third parties to recover past and future costs related to ground water contamination in our service areas. The cost of litigation is expensed as incurred and any settlement is first offset against such costs. The CPUC's general policy requires all proceeds from contamination litigation to be used first to pay transactional expenses, then to make customers whole for water treatment costs to comply with the CPUC's water quality standards. The CPUC allows for a risk-based consideration of contamination proceeds which exceed the costs of the remediation described above and may result in some sharing of proceeds with the shareholder, determined on a case by case basis. The CPUC has authorized various memorandum accounts that allow the Company to track significant litigation costs to request recovery of these costs in future filings and uses of proceeds to comply with CPUC's general policy. Other Legal Matters From time to time, the Company is involved in various disputes and litigation matters that arise in the ordinary course of business. The status of each significant matter is reviewed and assessed for potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and the amount of the range of loss can be estimated, a liability is accrued for the estimated loss in accordance with the accounting standards for contingencies. Legal proceedings are subject to uncertainties, and the outcomes are difficult to predict. Because of such uncertainties, accruals are based on the best information available at the time. While the outcome of these disputes and litigation matters cannot be predicted with any certainty, management does not believe when taking into account existing reserves the ultimate resolution of these matters will materially affect the Company's financial position, results of operations, or cash flows. The Company has recognized a liability of $3.5 million for all known legal matters as of December 31, 2015 mostly due to main and service leaks. The cost of litigation is expensed as incurred and any settlement is first offset against such costs. Any settlement in excess of the cost to litigate is accounted for on a case by case basis, dependant on the nature of the settlement. The California Regional Water Quality Control Board (“Water Control Board”) issued a complaint on November 17, 2014 which alleges that a subsidiary of the Company discharged approximately 8,207,560 gallons of drinking water into creeks located in California that caused the death of over 270 fish. The Company is discussing a settlement with the Water Control Board and expects to pay an administrative civil liability in the range of $0.5 million to $1.0 million in a cash payment and agreeing to replace aging infrastructure in the service area of the discharge.

SUMMARY OF SIGNIFICANT ACCOUN25

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2015
Accounting Policies [Abstract]
Revenue	Revenue Revenue generally includes monthly cycle customer billings for regulated water and wastewater services at rates authorized by regulatory commissions (plus an estimate for water used between the customer's last meter reading and the end of the accounting period) and billings to certain non-regulated customers at rates authorized by contract with government agencies. The Company's regulated water and related utility services requirements are authorized by the Commissions in the states in which we operate. The revenue requirements are intended to provide the Company a reasonable opportunity to recover its operating costs and earn a return on investments. For metered customers, Cal Water recognizes revenue from rates which are designed and authorized by the CPUC. Under the WRAM, Cal Water records the adopted level of volumetric revenues, which would include recovery of cost of service and a return on investments, as established by the CPUC for metered accounts (adopted volumetric revenues). In addition to volumetric-based revenues, the revenue requirements approved by the CPUC include service charges, flat rate charges, and other items not subject to the WRAM. The adopted volumetric revenue considers the seasonality of consumption of water based upon historical averages. The variance between adopted volumetric revenues and actual billed volumetric revenues for metered accounts is recorded as a component of revenue with an offsetting entry to a regulatory asset or liability balancing account (tracked individually for each Cal Water district) subject to certain criteria under the accounting for regulated operations being met. The variance amount may be positive or negative and represents amounts that will be billed or refunded to customers in the future. Cost-recovery rates are designed to permit full recovery of certain costs allowed to be recovered by the Commissions. Cost-recovery rates such as the MCBA provides for recovery of adopted expense levels for purchased water, purchased power and pump taxes, as established by the CPUC. In addition, cost-recovery rates include recovery of costs related to water conservation programs and certain other operating expenses adopted by the CPUC. Variances (which include the effects of changes in both rates and volumes for the MCBA) between adopted and actual costs are recorded as a component of revenue, as the amount of such variances will be recovered from or refunded to our customers at a later date. Cost-recovery expenses are generally recognized when expenses are incurred with no markup for return or profit. The balances in the WRAM and MCBA assets and liabilities accounts will fluctuate on a monthly basis depending upon the variance between adopted and actual results. The recovery or refund of the WRAM is netted against the MCBA over- or under-recovery for the corresponding district. The recovery or refund of net WRAM and MCBA balances are interest bearing at the current 90 day commercial paper rate. At the end of any calendar year, Cal Water files with the CPUC to refund or collect the balance in the accounts. Undercollected net WRAM and MCBA receivable balances are collected over 12 , 18 or 20 + months. Cal Water defers net WRAM and MCBA operating revenues and associated costs whenever the net receivable balances are estimated to be collected more than 24 months after the respective reporting periods in which it was recognized. The deferred net WRAM and MCBA revenues and associated costs were determined using forecasts of customer consumption trends for future reporting periods and the timing of when the CPUC will authorize Cal Water's filings to recover the undercollected balances. Deferred net WRAM and MCBA revenues and associated costs will be recognized as revenues and costs in future periods when collection is within 24 months of the respective reporting period. Customers meter reads occur on various business days throughout the month. As a result, there are unmetered or unbilled customer usage each month. The estimated unbilled revenue for monthly unmetered customer usage is recorded using the number of unbilled days for that month and average daily customer billing rate for the previous month. The average daily customer billing rate for the previous month fluctuates depending on customer usage. Estimated unbilled revenue is not included in the WRAM until it is billed. Flat rate customers are billed in advance at the beginning of the service period. The revenue is prorated so that the portion of revenue applicable to the current period is included in that period's revenue, with the remaining balance recorded as unearned revenue on the balance sheet and recognized as revenue when earned in the subsequent accounting period. The unearned revenue liability was $1.3 million and $1.5 million as of December 31, 2015 and 2014, respectively. This liability is included in "other accrued liabilities" on our consolidated balance sheets. Non-Regulated Revenue Revenues from non-regulated operations and maintenance agreements are recognized when services have been rendered to companies or municipalities under such agreements. For construction and design services, revenue is generally recognized on the completed contract method, as most projects are completed in less than 3 months . Other non-regulated revenue is recognized when title has transferred to the buyer, or ratably over the term of the lease.
Non-Regulated Revenue	Non-Regulated Revenue Revenues from non-regulated operations and maintenance agreements are recognized when services have been rendered to companies or municipalities under such agreements. For construction and design services, revenue is generally recognized on the completed contract method, as most projects are completed in less than 3 months . Other non-regulated revenue is recognized when title has transferred to the buyer, or ratably over the term of the lease.
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts The Company provides an allowance for doubtful accounts receivable. The allowance is based upon specific identified accounts plus an estimate of uncollectible accounts based upon historical percentages. The balance of customer receivables is net of the allowance for doubtful accounts at December 31, 2015 and 2014 of $0.7 million. The activities in the allowance for doubtful accounts are as follows: 2015 2014 Beginning Balance $ 697 $ 668 Provision for uncollectible accounts 1,674 1,561 Net write off of uncollectible accounts (1,641 ) (1,532 ) Ending Balance $ 730 $ 697
Utility Plant	Utility Plant Utility plant is carried at original cost when first constructed or purchased, or at fair value when acquired through acquisition. When depreciable plant is retired, the cost is eliminated from utility plant accounts and such costs are charged against accumulated depreciation. Maintenance of utility plant is charged to operating expenses as incurred. Maintenance projects are not accrued for in advance. Interest is capitalized on plant expenditures during the construction period and amounted to $1.9 million in 2015, $1.5 million in 2014, and $2.0 million in 2013. Intangible assets acquired as part of water systems purchased are recorded at fair value. All other intangibles have been recorded at cost and are amortized over their useful life. The following table represents depreciable plant and equipment as of December 31: 2015 2014 Equipment $ 499,502 $ 487,845 Office buildings and other structures 198,798 194,905 Transmission and distribution plant 1,603,541 1,508,444 Total $ 2,301,841 $ 2,191,194 Depreciation of utility plant for financial statement purposes is computed on a straight-line basis over the assets' estimated useful lives including cost of removal of certain assets as follows: Useful Lives Equipment 5 to 50 years Transmission and distribution plant 40 to 65 years Office Buildings and other structures 50 years The provision for depreciation expressed as a percentage of the aggregate depreciable asset balances was 2.80% in 2015, 2.97% in 2014, and 3.0% 2013. For income tax purposes, as applicable, the Company computes depreciation using the accelerated methods allowed by the respective taxing authorities.
Asset Retirement Obligation	Asset Retirement Obligation The Company has a legal obligation to retire wells in accordance with State Water Resources Control Board regulations. In addition, upon decommission of a wastewater plant or lift station certain wastewater infrastructure would need to be retired in accordance with State Water Resources Control Board regulations. An asset retirement cost and corresponding retirement obligation is recorded when a well or waste water infrastructure is placed into service. As of December 31, 2015 and 2014, the retirement obligation is estimated to be $19.5 million and $18.4 million, respectively. The change only impacted the consolidated balance sheet.
Cash Equivalents	Cash Equivalents Cash equivalents include highly liquid investments with remaining maturities of three months or less at the time of acquisition. Cash and cash equivalents was $8.8 million and $19.6 million as of December 31, 2015 and December 31, 2014, respectively.
Restricted Cash	Restricted Cash In 2015 restricted cash includes $0.4 million of proceeds collected through a surcharge on certain customers' bills plus interest earned on the proceeds and is used to service California Safe Drinking Water Bond obligations. All restricted cash is included in "taxes, prepaid expenses, and other assets". As of December 31, 2015 and 2014, restricted cash was $0.5 million and $0.9 million, respectively.
Regulatory Assets and Liabilities	Regulatory Assets and Liabilities Regulatory assets and liabilities were comprised of the following as of December 31: 2015 2014 Regulatory Assets Pension and retiree group health $ 205,614 $ 245,008 Property-related temporary differences (tax benefits flowed through to customers) 81,522 72,350 Other accrued benefits 27,327 32,959 Interim rates long-term accounts receivable 5,238 10,627 Net WRAM and MCBA long-term accounts receivable 15,410 14,449 Asset retirement obligations, net 14,682 13,863 Tank coating 6,829 — Health care balancing account 3,503 1,075 Other regulatory assets 1,768 — Total Regulatory Assets $ 361,893 $ 390,331 Regulatory Liabilities Future tax benefits due customers $ 29,505 $ 26,114 Conservation program 2,317 2,669 Pension balancing account 792 4,291 Other liabilities 2,650 3,373 Total Regulatory Liabilities $ 35,264 $ 36,447 Short-term regulatory assets and liabilities are excluded from the above table. The short-term regulatory assets for 2015 and 2014 were $35.1 million and $53.2 million, respectively. The short-term regulatory assets were primarily interim rates and net WRAM and MCBA. The short-term portion of regulatory liabilities for 2015 and 2014 were $2.2 million and $6.1 million, respectively. The short-term regulatory liabilities were primarily net WRAM and MCBA liability balances and net refund balances to customers for conservation program from the 2009 general rate case. The Company operates extensively in a regulated business, and as such is subject to the accounting standards for regulated utilities. Utility companies defer costs and credits on the balance sheet as regulatory assets and liabilities when it is probable that those costs and credits will be recognized in the ratemaking process in a period different from the period in which they would have been reflected in income by an unregulated company. Regulatory assets other than WRAM represent deferral of costs that will be recovered in the future and do not earn a return. In determining the probability of costs being recognized in other periods, the Company considers regulatory rules and decisions, past practices, and other facts or circumstances that would indicate if recovery is probable. In the event that a portion of the Company's operations were no longer subject to the accounting standards for regulated utilities, the Company would be required to write off related regulatory assets and liabilities. If a commission determined that a portion of the Company's assets were not recoverable in customer rates, the Company would be required to determine if a disallowance of assets had occurred. If a disallowance had occurred, it would require a write-down in the assets' recorded balance. The Company's pension and postretirement health care benefits regulatory asset is the amount the Company expects to recover from customers in the future for these plans at the end of the calendar year. The property-related temporary differences were primarily due to the difference between book and federal income tax depreciation on utility plant that was placed in service before the regulatory Commissions adopted normalization for rate making purposes. Full normalization requires no flow-through of tax benefits to customers. The regulatory asset will be recovered in rates in future periods as the tax effects of the temporary differences previously flowed-through to customers reverse. Other accrued benefits are accrued benefits for vacation, self-insured workers' compensation, and directors' retirement benefits. The net WRAM and MCBA long-term accounts receivable is the undercollected portion of recorded revenues that are not expected to be collected from customers within 12 months . The asset retirement obligation regulatory asset represents the difference between costs associated with asset retirement obligations and amounts collected in rates. The health care balancing account regulatory asset is for incurred health care costs that exceeded the cost recovery in rates and is recoverable from customers as of December 31, 2015 . Tank coating represents the maintenance costs for tank coating projects that are recoverable from customers as of December 31, 2015. The future tax benefits due to customers represent regulatory liabilities for tax deductions that will be taken and flowed through to customers in the future. Regulatory liabilities also reflect timing differences provided at higher than the current tax rate, which will flow-through to future customers. The conservation program and pension balancing account regulatory liabilities are for cost recovery in rates that exceeded incurred costs and are refundable to customers as of December 31, 2015 .
Impairment of Long-Lived Assets, Intangibles and Goodwill	Impairment of Long-Lived Assets, Intangibles and Goodwill The Company's long-lived assets include transmission and distribution plant, equipment, land, buildings, and intangible assets. Long-lived assets, other than land, are depreciated or amortized over their estimated useful lives, and are reviewed for impairment whenever changes in circumstances indicate the carrying value of the assets may not be recoverable. Such circumstances would include items such as a significant decrease in the market value of a long-lived asset, a significant adverse change in the manner in which the asset is being used or planned to be used or in its physical condition, or a history of operating or cash flow losses associated with the uses of the asset. In addition, changes in the expected useful life of these long-lived assets may also be an impairment indicator. When such events or changes occur, we estimate the fair value of the asset from future cash flows expected to result from the use and, if applicable, the eventual disposition of the assets, and compare that to the carrying value of the asset. If the carrying value is greater than the fair value,an impairment loss is recognized equal to the amount by which the asset's carrying value exceeds its fair value. The key variables that must be estimated include assumptions regarding sales volume, rates, operating costs, labor and other benefit costs, capital additions, assumed discount rates and other economic factors. These variables require significant management judgment and include inherent uncertainties since they are forecasting future events. A variation in the assumptions used could lead to a different conclusion regarding the realizability of an asset and, thus could have a significant effect on the consolidated financial statements. Goodwill is measured as the excess of the cost of an acquisition over the sum of the amounts assigned to identifiable assets acquired less liabilities assumed. Goodwill is not amortized but instead is reviewed annually at November 30 th for impairment or more frequently if impairment indicators arise. The impairment test is performed at the reporting unit level using a two- step, fair-value based approach. The first step determines the fair value of the reporting unit and compares it to the reporting unit's carrying value. If the fair value of the reporting unit is less than its carrying amount, a second step is performed to measure the amount of impairment loss, if any. The second step allocates the fair value of the reporting unit to the Company's tangible and intangible assets and liabilities. This derives an implied fair value for the reporting unit's goodwill. If the carrying amount of the reporting unit's goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized equal to the excess.
Long-Term Debt Premium, Discount and Expense	Long-Term Debt Premium, Discount and Expense The premiums, discounts, and issuance expenses on long-term debt are amortized over the original lives of the related debt on a straight-line basis which approximates the effective interest method. Premiums paid on the early redemption of certain debt and the unamortized original issuance discount and expense are amortized over the life of new debt issued in conjunction with the early redemption. Amortization expense included in interest expense was $0.8 million, $0.8 million, and $1.1 million for 2015, 2014, and 2013, respectively.
Advances for Construction	Advances for Construction Advances for construction consist of payments received from developers for installation of water production and distribution facilities to serve new developments. Advances are excluded from rate base for rate setting purposes. Annual refunds are made to developers without interest. Advances of $180.2 million, and $182.3 million at December 31, 2015 and 2014, respectively, will be refunded primarily over a 40 -year period in equal annual amounts. Estimated refunds of advances for the succeeding 5 years are approximately $7.9 million in 2016, $7.7 million in 2017, $7.7 million in 2018, $7.6 million in 2019, and $7.6
Contributions in Aid of Construction	Contributions in Aid of Construction Contributions in aid of construction represent payments received from developers, primarily for fire protection purposes, which are not subject to refunds. Facilities funded by contributions are included in utility plant, but excluded from rate base. Depreciation related to assets acquired from contributions is charged to the Contributions in Aid of Construction account.
Income Taxes	Income Taxes The Company accounts for income taxes using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Measurement of the deferred tax assets and liabilities is at enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the period that includes the enactment date. The Company evaluates the need for a valuation allowance on deferred tax assets based on historical taxable income and projected taxable income for future tax years. Historically the Commissions reduced revenue requirements for the tax effects of certain originating temporary differences and allowed recovery of these tax costs as the related temporary differences reverse. The Commissions have granted the Company rate increases to reflect the normalization of the tax benefits of the federal accelerated methods and available Investment Tax Credits (ITC) for all assets placed in service after 1980. ITCs are deferred and amortized over the lives of the related properties for book purposes. The CPUC granted flow-through for state taxes. Advances for Construction and Contributions in Aid of Construction received from developers subsequent to 1986 were taxable for federal income tax purposes and subsequent to 1991 were subject to California income tax. In 1996, the federal tax law, and in 1997, the California tax law, changed and only deposits for new services were taxable. In late 2000, federal regulations were further modified to exclude contributions of fire services from taxable income. The accounting standards for accounting for uncertainty in income taxes allows the inclusion of interest and penalties related to uncertain tax positions as a component of income taxes. See note 10 "Income Taxes".
Workers' Compensation	Workers' Compensation For workers' compensation, the Company estimates the liability associated with claims submitted and claims not yet submitted based on historical data. Expenses for workers compensation insurance are included in rates on a pay-as- you-go basis. Therefore, a corresponding regulatory asset has been recorded.
Earnings per Share	Earnings per Share The computations of basic and diluted earnings per share are noted below. Basic earnings per share are computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share reflect the potential dilution that could occur if securities or other contracts were exercised or converted into common stock. Restricted Stock Awards (RSAs) are included in the common shares outstanding because the shares have all the same voting and dividend rights as issued and unrestricted common stock. The Company did not grant any Stock Appreciation Rights (SARs) in 2015, 2014, and 2013. SARs outstanding were 64,500 shares as of December 31, 2015, 186,356 shares as of December 31, 2014, and 283,856 shares as of December 31, 2013. All SARs were dilutive in 2015, 2014 and 2013. The dilutive effect is shown in the table below: 2015 2014 2013 (In thousands, Net income as reported and available to common stockholders $ 45,017 $ 56,738 $ 47,254 Weighted average common shares, basic 47,865 47,791 46,384 Dilutive common stock equivalents (treasury method) 15 38 33 Shares used for dilutive calculation 47,880 47,829 46,417 Earnings per share—basic $ 0.94 $ 1.19 $ 1.02 Earnings per share—diluted $ 0.94 $ 1.19 $ 1.02
Stock-based Compensation	Stock-based Compensation Stock-based compensation cost is measured at the grant date based on the fair value of the award. The Company recognizes compensation expense on a straight-line basis over the requisite service period, which is the vesting period.
Comprehensive Income or Loss	Comprehensive Income or Loss Comprehensive income for all periods presented was the same as net income.
Accumulated Other Comprehensive Income	Accumulated Other Comprehensive Income The Company did not have any accumulated other comprehensive income or loss transactions for 2015 and 2014.
Adoption of New Accounting Standards	New Accounting Standards On November 10, 2015 the Financial Accounting Standards Board (FASB) issued an accounting standards update (ASU) 2015-17, Balance Sheet Classification of Deferred Taxes . This update requires the presentation of deferred tax assets and liabilities as noncurrent assets and liabilities in the balance sheet. ASU 2015-17 is effective for annual reporting periods beginning after December 15, 2016 and early adoption is permitted. In 2015, the Company implemented ASU 2015-17 as of the year ended December 31, 2015 on a prospective basis and the prior periods have not been retrospectively adjusted. On May 28, 2014 the FASB issued an ASU 2014-9, Revenue from Contracts with Customers . This update creates a single, principles based framework for revenue recognition and is based on principles that govern the recognition of revenue at an amount an entity expects to be entitled when goods or services are transferred to customers. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, deferring the effective date of this amendment for public companies by one year to January 1, 2018, with early adoption permitted as of the original effective date of January 1, 2017. The Company is currently evaluating the impact of adopting the new revenue standard on its consolidated financial statements and related disclosures.
