CALIFORNIA WATER SERVICE GROUP

Notes to Unaudited Condensed Consolidated Financial Statements

June 30, 2017

Dollar amounts in thousands unless otherwise stated

Note 1. Organization and Operations and Basis of Presentation

California Water Service Group (the 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 herein 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 unaudited condensed consolidated interim financial information has been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) for interim financial information and in accordance with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X promulgated by the Securities and Exchange Commission (SEC) and therefore do not contain all of the information and footnotes required by GAAP and the SEC for annual financial statements. The unaudited condensed consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements for the year ended December 31, 2016, included in its annual report on Form 10-K as filed with the SEC on February 23, 2017.

The preparation of the Company’s unaudited condensed consolidated interim 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 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, 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.

In the opinion of management, the accompanying unaudited condensed consolidated interim financial statements reflect all adjustments, consisting of normal recurring transactions that are necessary to provide a fair presentation of the results for the periods covered. The results for interim periods are not necessarily indicative of the results for any future period.

Due to the seasonal nature of the water business, the results for interim periods are not indicative of the results for a 12-month period. Revenue and income are generally higher in the warm, dry summer months when water usage and sales are greater. Revenue and income are generally lower in the winter months when cooler temperatures and rainfall curtail water usage and sales.

Note 2. Summary of Significant Accounting Policies

Revenue

Revenue generally includes monthly cycle customer billings for regulated water and wastewater services at rates authorized by the 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 wastewater revenue requirements are authorized by the Commissions in the states in which they 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 California Public Utilities Commission (CPUC). Under the Water Revenue Adjustment Mechanism (WRAM), Cal Water records the adopted level of volumetric revenues, which would include recovery of cost of service and a return on investments, as

7

established by the CPUC for metered accounts. 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 guidance for regulated operations. The variance amount represents amounts that will be billed or refunded to customers in the future. In addition to volumetric revenues, the revenue requirements approved by the CPUC include service charges, flat rate charges, and other items not subject to the WRAM.

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 Modified Cost Balancing Account (MCBA) provide 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 customers in the future. Cost-recovery expenses are generally recognized when expenses are incurred with no markup for return on investments 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 and the deferred net balances are interest bearing at the current 90 day commercial paper rate. Subsequent to calendar year-end, Cal Water files with the CPUC to refund or collect the balance in the accounts. The majority of under-collected net WRAM and MCBA receivable balances are collected over 12 or 18 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 period in which it was recorded. The deferred net WRAM and MCBA revenue and associated costs were determined using forecasts of customer consumption trends in future reporting periods and the estimated timing of when the CPUC will authorize Cal Water's filings to recover unbilled balances. Deferred revenues and associated costs are recorded in the periods when the 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 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 $0.8 million as of June 30, 2017 and December 31, 2016, respectively. This liability is included in “accrued expenses and other liabilities” on the condensed consolidated balance sheets.

Allowance for Funds Used During Construction

The allowance for funds used during construction (AFUDC) represents the capitalized cost of funds used to finance the construction of the utility plant. In general, AFUDC is applied to Cal Water construction projects requiring more than one month to complete. No AFUDC is applied to projects funded by customer advances for construction, contributions in aid of construction, or applicable state-revolving fund loans. AFUDC includes the net cost of borrowed funds and a rate of return on other funds when used, and is recovered through water rates as the utility plant is depreciated. Cal Water was authorized by the CPUC to record AFUDC on construction work in progress effective January 1, 2017. Prior to January 1, 2017, the CPUC authorized Cal Water to only record capitalized interest on borrowed funds. Cal Water previously reported the amounts authorized as capitalized interest and a reduction to interest expense. The amount of AFUDC related to equity funds and to borrowed funds for the three and six month periods ended June 30, 2017 and 2016 are shown in the tables below:

8

	Three Months Ended June 30
	2017		2016		Change
Allowance for equity funds used during construction	$	879	$	—	$	879
Allowance for borrowed funds used during construction	564		837		(273		)
Total	$	1,443	$	837	$	606

	Six Months Ended June 30
	2017		2016		Change
Allowance for equity funds used during construction	$	1,658	$	—	$	1,658
Allowance for borrowed funds used during construction	1,058		1,567		(509		)
Total	$	2,716	$	1,567	$	1,149

Cash and Cash Equivalents

Cash equivalents include highly liquid investments with maturities of three months or less.  Cash and cash equivalents was $29.1 million and $25.5 million as of June 30, 2017 and December 31, 2016, respectively.  Restricted cash was presented on the condensed consolidated balance sheet in “taxes, prepaid expenses and other assets” and was $1.0 million and $0.4 million as of June 30, 2017 and December 31, 2016, respectively.

Adoption of New Accounting Standards

In March 2016, the Financial Accounting Standards Board (FASB) issued updated accounting guidance on simplifying the accounting for share-based payments (ASU 2016-09), which includes the accounting for share-based payment transactions, the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The Company adopted and implemented the changes to accounting for share-based payments on January 1, 2017 and applied the requirements retrospectively on the statement of cash flows for all periods presented. The Company's forfeiture policy did not change and the Company continues to account for forfeitures when they occur. For the six month period ended June 30, 2016, the Company recorded $0.5 million of income tax benefits in excess of compensation costs for share-based compensation which reduced the effective tax rate. The tax-related cash flows resulting from share-based payments were reported as operating activities and the associated cash paid by the company for employee tax withholding transactions were reported as financing activities on the consolidated statement of cash flows.

The following table shows the effect of the accounting change to the Condensed Consolidated Statements of Cash Flows for the six month period ended June 30, 2016:

	Six Months Ended June 30, 2016
Cash Flow Classification	As Reported on Form 10-Q		Adjusted Balance on Form 10-Q			Increase (Decrease) from Retrospective Adoption
Other changes in noncurrent assets and liabilities	$	16,209	$	16,757		$	548
Net cash provided by operating activities	59,063		59,611			548
Repurchase of common stock	—		(548		)	(548		)
Net cash provided by financing activities	80,304		79,756			(548		)

New Accounting Standards

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which amends the existing revenue recognition guidance.  In August 2015, the FASB deferred 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 expects to adopt the new revenue standard using the modified retrospective method and does not expect the ASU to materially impact the timing or recognition of revenue related to the sale and delivery of water to their customers, which is a significant percentage of the Company's revenue. The Company is still evaluating the impact the ASU has on the related revenue disclosures.

In February 2016, the FASB issued ASU 2016-02, Leases. This update changes the accounting treatment of operating leases for lessees and related disclosure requirements. ASU 2016-02 is effective for annual reporting periods beginning

9

after December 15, 2018 and early adoption is permitted. The Company will adopt the standard using the modified retrospective method for its existing leases and is currently evaluating the impact of adopting the new lease standard on its consolidated financial statements and related disclosures.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230) - Classification of Certain Cash Receipts and Cash Payments. This update adds and clarifies guidance on the classification of certain cash receipts and payments in the statement of cash flows. ASU 2016-15 is effective for annual periods beginning after December 15, 2017 and early adoption is permitted. The Company is currently evaluating the impact on its consolidated financial statements and related disclosures.

In March 2017, the FASB issued Accounting Standards Update No. 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost (“ASU 2017-07”). The update requires employers to present the service cost component of the net periodic benefit cost in the same income statement line item as other employee compensation costs arising from services rendered during the period. The other components of net benefit cost, including interest cost, expected return on plan assets, amortization of prior service cost/credit and actuarial gain/loss, and settlement and curtailment effects, are to be presented as non-operating items. Employers will have to disclose the line(s) used to present the other components of net periodic benefit cost, if the components are not presented separately in the income statement. The standard only allows the service cost component to be eligible for capitalization. ASU 2017-07 is effective for annual periods after December 15, 2017, and early adoption is permitted. The Company is currently evaluating the impact on its consolidated financial statements and related disclosures. The adoption of this guidance will change the Company's financial statement presentation of net benefit costs. However, based on current regulatory authorization, the changes required by the standard are not expected to materially impact the results of operations.

Note 3. Stock-based Compensation

Equity Incentive Plan

During the six months ended June 30, 2017 and 2016, the Company granted annual Restricted Stock Awards (RSAs) of 48,717 and 72,317, respectively, to officers and directors of the Company. During those same periods, 14,186and 10,600 RSAs were canceled, respectively. During the three months ended June 30, 2017 and 2016, no RSAs were granted and 3,284 and 2,869 RSAs were canceled, respectively. Employee RSAs granted in 2017 and 2016 vest over 36 months.  Director RSAs generally vest at the end of 12 months. During the first six months of 2017 and 2016, the RSAs granted were valued at $36.75 and $25.17 per share, respectively, based upon the fair market value of the Company’s common stock on the date of grant.

During the six months ended June 30, 2017 and 2016, the Company granted 31,389 and 43,659 performance-based Restricted Stock Unit Awards (RSUs), respectively, to officers. During those same periods, the Company issued 38,709 and 28,424 RSUs, respectively, and canceled 19,735 and 6,602 RSUs, respectively.During the three months ended June 30, 2017 and 2016, the Company did not grant, issue or cancel any RSUs. Each RSU award reflects a target number of shares that may be issued to the award recipient. The 2017 and 2016 awards may be earned upon the completion of the three-year performance and are recognized as expense ratably over the three-year performance period using a fair market value of $36.75 per share and $25.17 per share, respectively, and an estimate of RSUs earned during the performance period. The Company has recorded compensation costs for the RSAs and RSUs in administrative and general operating expenses in the amount of $1.5 million and $1.4 million for the six months ended June 30, 2017 and June 30, 2016, respectively.

Note 4. Equity

The Company’s changes in total common stockholders’ equity for the six months ended June 30, 2017 were as follows:

Note 5. Earnings Per Share

The computations of basic and diluted earnings per share are noted below. Basic earnings per share is computed by dividing the net income available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts were exercised or converted into common stock. RSAs are included in the weighted average common shares outstanding because the shares have all the same voting and dividend rights as issued and unrestricted common stock. RSUs are not included in diluted shares for financial reporting until authorized by the Compensation & Organization Committee of the Board of Directors

There were no shares of Stock Appreciation Rights (SARs) outstanding as of June 30, 2017 and as of June 30, 2016. All the SARs were dilutive when they were outstanding during the period, as shown in the tables below.

Note 6. Pension Plan and Other Postretirement Benefits

The Company provides a qualified, defined-benefit, non-contributory pension plan for substantially all employees. The Company makes annual contributions to fund the amounts accrued for in the qualified pension plan. The Company also maintains an unfunded, non-qualified, supplemental executive retirement plan. The costs of the plans are charged to expense or are capitalized in utility plant as appropriate.

The Company offers medical, dental, vision, and life insurance benefits for retirees and their spouses and dependents. Participants are required to pay a premium, which offsets a portion of the cost.

Cash contributions by the Company related to pension plans were $14.8 million and $14.0 million for the six months ended June 30, 2017 and June 30, 2016, respectively. There were no cash contributions by the Company to other postretirement benefit plans for the six months ended June 30, 2017 and $3.3 million of contributions for the six months ended June 30, 2016. The total 2017 estimated cash contribution to the pension plans is $29.5 million and to the other postretirement benefit plans is $9.3 million.

The following table lists components of net periodic benefit costs for the pension plans and other postretirement benefits. The data listed under “pension plan” includes the qualified pension plan and the non-qualified supplemental executive retirement plan. The data listed under “other benefits” is for all other postretirement benefits.

Note 7. Short-term and Long-term Borrowings

In March 2016, Cal Water issued the remaining $50.0 million of First Mortgage Bonds, consisting of $40.0 million of 4.41% series SSS maturing April 16, 2046 and $10.0 million of 4.61% series TTT maturing April 14, 2056. Cash proceeds of approximately $49.7 million, net of $0.3 million debt issuance costs, were received. Cal Water used a portion of the net proceeds from the offering to repay outstanding borrowings on the Company and Cal Water lines of credit of $48.6 million.

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 capitalization ratio and interest coverage ratio.

The outstanding borrowings on the Company lines of credit were $55.1 million and $57.1 million as of June 30, 2017 and December 31, 2016, respectively. There were $135.0 million and $40.0 million borrowings on the Cal Water lines of credit as of June 30, 2017 and December 31, 2016, respectively.  The average borrowing rate for borrowings on the Company and Cal Water lines of credit during the six months ended June 30, 2017 was 1.82% compared to 1.30% for the same period last year.

Note 8. Income Taxes

The Company accounts for income taxes under the provisions of ASC 740, Accounting for Income Taxes. The Company adjusts its effective tax rate each quarter to be consistent with the estimated annual effective tax rate. The Company also records the tax effect of unusual or infrequently occurring discrete items.

The provision for income taxes consists of the following:

	Three Months Ended June 30
	2017		2016
Income tax provision	$	10,852	$	7,254

	Six Months Ended June 30
	2017		2016
Income tax provision	$	10,857	$	6,510

The increase in the income tax provision for three months ended June 30, 2017 as compared to the three months ended June 30, 2016 was due primarily to an increase in the Company’s earnings in 2017 as compared to 2016, which was partially offset by a $0.1 million tax benefit associated with the settlement of equity awards in 2017. 

The increase in the income tax provision for six months ended June 30, 2017 as compared to the six months ended June 30, 2016 was due primarily to an increase in the Company’s earnings in 2017 as compared to 2016, which was partially offset by a $0.5 million tax benefit associated with the settlement of equity awards in 2017. The Company’s fiscal year 2017 effective tax rate is estimated to be 37%.

As of June 30, 2017 and December 31, 2016, the Company had unrecognized tax benefits of approximately $10.2 million. Included in the balance of unrecognized tax benefits as of June 30, 2017 and December 31, 2016 is approximately $1.9 million of tax benefits that, if recognized, would result in an adjustment to the Company’s effective tax rate. The Company does not expect its unrecognized tax benefits to change significantly within the next 12 months.

Note 9. Regulatory Assets and Liabilities

Other regulatory liabilities	804		3,614
Total Regulatory Liabilities	$	40,569	$	38,735

Short-term regulatory assets and liabilities are excluded from the above table. The short-term regulatory assets were $29.1 million as of June 30, 2017 and $30.3 million as of December 31, 2016. The short-term regulatory assets were primarily net WRAM and MCBA accounts receivable, 2012 General Rate Case (GRC) health cost balancing account receivable, 2014-2015 drought recovery, interim rate memorandum account receivable, and East LA memorandum accounts receivable as of June 30, 2017 and December 31, 2016. The short-term portions of regulatory liabilities were $6.7 million as of June 30, 2017 and $4.8 million as of December 31, 2016. As of June 30, 2017, the short-term regulatory liabilities were primarily net WRAM and MCBA liability balances, refund balance from an interim rates true up authorized prior to the 2009 GRC, net refund balances to customers for the pension and conservation programs from the 2012 GRC. As of December 31, 2016, the short-term regulatory liabilities were primarily net WRAM and MCBA liability balances and net refund balances to customers for the pension and conservation programs from the 2012 GRC.

Note 10. Commitments and Contingencies

Commitments

The Company has significant commitments to lease certain office spaces and water systems and to purchase water from water wholesalers. These commitments are described in Form 10-K for the year ended December 31, 2016. As of June 30, 2017, there were no significant changes from December 31, 2016.

14

Contingencies

Groundwater Contamination

The Company has undertaken litigation against third parties to recover past and anticipated costs related to groundwater 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 groundwater contamination litigation to be used first to pay transactional expenses, then to make ratepayers 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. As of June 30, 2017 and December 31, 2016, the Company recognized a liability of $6.2 million and $6.0 million, respectively, for known legal matters. 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, dependent on the nature of the settlement.

Note 11. Fair Value of Financial Assets and Liabilities

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 hierarchical 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.

15

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 1.70%.

Advances for construction fair values were estimated using broker quotes from companies that frequently purchase these investments.

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Dollar amounts in thousands unless otherwise stated

FORWARD LOOKING STATEMENTS

This quarterly report, including all documents incorporated by reference, contains forward-looking statements within the meaning established by the Private Securities Litigation Reform Act of 1995 (Act). Forward-looking statements in this quarterly report are based on currently available information, expectations, estimates, assumptions and projections, and our management’s beliefs, assumptions, judgments and expectations about us, the water utility industry and general economic conditions.

The forward-looking statements are not guarantees of future performance. They are based on numerous assumptions that we believe are reasonable, but they are open to a wide range of uncertainties and business risks. Consequently, actual results may vary materially from what is contained in a forward-looking statement.

Factors which may cause actual results to be different than those expected or anticipated include, but are not limited to:

• governmental and regulatory commissions’ decisions, including decisions on proper disposition of property;

• consequences of eminent domain actions relation to our water systems;

• our ability to recover costs;

• availability of water supplies;

• issues with the implementation, maintenance or security of our information technology systems;

• civil disturbances or terrorist threats or acts, or apprehension about the possible future occurrences of acts of this type;

• labor relations matters as we negotiate with the unions;

• restrictive covenants in or changes to the credit ratings on current or future debt that could increase financing costs or affect the ability to borrow, make payments on debt, or pay dividends;

• changes in customer water use patterns and the effects of conservation;

• the impact of weather, climate, natural disasters, and diseases on water quality, water availability, water sales and operating results;

• the risks set forth in “Risk Factors” included in the Company's annual report on 2016 Form 10-K.

In light of these risks, uncertainties and assumptions, investors are cautioned not to place undue reliance on forward-looking statements, which speak only as of the date of this quarterly report or as of the date of any document incorporated by reference in this report, as applicable. When considering forward-looking statements, investors should keep in mind the cautionary statements in this quarterly report and the documents incorporated by reference. We are not under any obligation, and we expressly disclaim any obligation, to update or alter any forward-looking statements, whether as a result of new information, future events or otherwise.

CRITICAL ACCOUNTING POLICIES

We maintain our accounting records in accordance with accounting principles generally accepted in the United States of America (GAAP) and as directed by the Commissions to which our operations are subject. The process of preparing financial statements in accordance with GAAP requires the use of estimates on the part of management. The estimates used by management are based on historic experience and an understanding of current facts and circumstances. Management believes that the following accounting policies are critical because they involve a higher degree of complexity and judgment, and can have a material impact on our results of operations, financial condition, and cash flows of the business. These policies and their key characteristics are discussed in detail in the 2016 Form 10-K. They include:

• revenue recognition;

• regulated utility accounting;

• income taxes;

• pension and postretirement health care benefits;

For the six month period ended June 30, 2017, there were no changes in the methodology for computing critical accounting estimates, no additional accounting estimates met the standards for critical accounting policies, and there were no material changes to the important assumptions underlying the critical accounting estimates.

RESULTS OF SECOND QUARTER 2017 OPERATIONS

COMPARED TO SECOND QUARTER 2016 OPERATIONS

Dollar amounts in thousands unless otherwise stated

Overview

Net income for the three month period ended June 30, 2017, was $18.5 million or $0.39 per diluted common share compared to net income of $11.5 million or $0.24 per diluted common share for the three month period ended June 30, 2016, an increase of $7.0 million. The increase in net income was primarily the result of Cal Water's 2015 General Rate Case (GRC) rate increases. Also increasing net income were an increase in unbilled revenue, decreases in emergency drought incremental costs and maintenance expenses, unrealized gains on our benefit plan investments, and an increase resulting from the implementation of allowance for equity funds used during construction in 2017. These increases to net income were partially offset by increases in depreciation and amortization, interest, and employee wage expenses. The increase in accrued unbilled revenue resulted from higher water usage at the end of the quarter. This increase in accrued unbilled revenue is not included in the WRAM until it is billed. The WRAM account records changes in billed revenue. Accrued unbilled revenue is seasonal and the pattern of accrued unbilled revenue changes can fluctuate on a year-to-year basis.

Operating Revenue

Operating revenue increased $18.7 million, or 12.3%, to $171.1 million in the second quarter of 2017 as compared to the second quarter of 2016. The factors that impacted the operating revenue for the second quarter of 2017 as compared to 2016 are as follows:

Net change due to rate changes, usage, and other (1)	$	21,237
MCBA Revenue (2)	(1,035		)
Other balancing account revenue (3)	(261		)
Deferral of revenue (4)	(1,254		)
Net operating revenue increase	$	18,687

1. The net change due to rate changes, usage, and other in the above table was mainly driven by rate increases and a $2.5 million increase in accrued unbilled revenue. The components of the rate increases are as follows:

26

General rate case	$	11,538
Purchased water and pump tax offset increases	4,945
Ratebase offset increases	677
Total increase in rates	$	17,160

2. The MCBA revenue decrease resulted from an increase in adopted water production costs relative to actual water production costs in the second quarter of 2017 as compared to the second quarter of 2016. The adopted water production costs increased in 2017 as a result of Cal Water's 2015 GRC. As required by the MCBA mechanism, the increase in adopted water production costs relative to actual water production costs in California also decreased operating revenue for the same amount.

3. The other balancing account revenue consists of the pension, conservation and health care balancing account revenues. Pension and conservation balancing account revenues are the differences between actual expenses and adopted rate recovery. Health care balancing account revenue is 85% of the difference between actual health care expenses and adopted rate recovery. The decrease in revenue was mainly due to a decrease in actual health care and conservation expenses relative to adopted in the second quarter of 2017 as compared to the second quarter of 2016. This was partially offset by an increase in actual pension expenses relative to adopted in the second quarter of 2017 as compared to the second quarter of 2016.

4. The deferral of revenue consists of amounts that are expected to be collected from customers beyond 24 months following the end of the accounting period in which these revenues were recorded. The deferral increased in the second quarter of 2017 as compared to the second quarter of 2016 due to an increase in the balancing account revenue expected to be collected beyond 24 months.

Total Operating Expenses

Total operating expenses increased $12.0 million, or 8.9%, to $145.9 million in the second quarter of 2017, as compared to $133.9 million in the second quarter of 2016.

Water production costs consists of purchased water, purchased power, and pump taxes. It represents the largest component of total operating expenses, accounting for approximately 44.0% of total operating expenses in the second quarter of 2017, as compared to 43.0% of total operating expenses in the second quarter of 2016. Water production costs increased 11.4% as compared to the same period last year mainly due to a blended 5.0% increase in purchased water wholesaler rates and a 6.1% increase in purchased water production.

Sources of water as a percent of total water production are listed in the following table:

	Three Months Ended June 30
	2017		2016
Well production	48	%	49	%
Purchased	47	%	47	%
Surface	5	%	4	%
Total	100	%	100	%

The components of water production costs are shown in the table below:

	Three Months Ended June 30
	2017		2016		Change
Purchased water	$	53,322	$	47,650	$	5,672
Purchased power	7,601		7,039		562
Pump taxes	3,208		2,900		308
Total	$	64,131	$	57,589	$	6,542

Administrative and general and other operations expenses decreased $0.2 million to $42.1 million in the second quarter of 2017, as compared to $42.3 million in the second quarter of 2016. The decrease was primarily mainly due to a decrease in

27

California drought program incremental costs, the deferral of MCBA costs associated with the deferral of operating revenue, a decrease in health care benefit costs, and insurance proceeds to recover most of the 2016 wild fire damages in our southern California District. These decreases were partially offset by employee wage and pension benefit cost increases. Changes in employee pension and other postretirement benefit costs, and employee health care costs for regulated California operations do not affect net income, because the Company is allowed by the CPUC to track these costs in balancing accounts for future recovery, which creates a corresponding change to operating revenue. At June 30, 2017, there were 1,157 employees and at June 30, 2016, there were 1,150 employees. 

Maintenance expense decreased $1.2 million, or 20.7%, to $4.7 million in the second quarter of 2017, as compared to $5.9 million in the second quarter of 2016, mostly due to decreases in transmission and distribution mains repairs.

Depreciation and amortization expense increased $3.4 million, or 21.3%, to $19.2 million in the second quarter of 2017, as compared to $15.8 million in the second quarter of 2016, due to 2016 capital additions.

Income taxes increased $2.7 million, or 40.3%, to $9.6 million in the second quarter of 2017, as compared to $6.9 million in the second quarter of 2016. The increase was mainly due to an increase in operating income in the second quarter of 2017 as compared to the second quarter of 2016.

Property and other taxes increased $0.7 million, or 12.0%, to $6.1 million in the second quarter of 2017, as compared to $5.4 million in the second quarter of 2016, mostly due to an increase in assessed property values in 2016 and increased local franchise taxes.

Other Income and Expenses

Net other income and expenses increased $1.2 million to $1.8 million in the second quarter of 2017, as compared to $0.6 million in the second quarter of 2016, principally due to the implementation of allowance for equity funds used during construction in 2017 and a $0.5 million increase in unrealized gains on our benefit plan investments.

Interest Expense

Net interest expense increased $0.9 million, or 12.1%, to $8.5 million in the second quarter of 2017, as compared to $7.6 million in the second quarter of 2016. The increase was due primarily to an increase in short term financing for capital investments as well as increased short-term interest rates.

RESULTS OF THE SIX MONTHS ENDED JUNE 30, 2017 OPERATIONS

COMPARED TO THE SIX MONTHS ENDED JUNE 30, 2016 OPERATIONS

Dollar amounts in thousands unless otherwise stated

Overview

Net income for the six months ended June 30, 2017, was $19.7 million or $0.41 per diluted common share compared to a net income of $10.7 million or $0.22 per diluted common share for the six months ended June 30, 2016, an increase of $9.0 million. The increase in net income was primarily the result of Cal Water's 2015 GRC rate increases. Also increasing net income were decreases in emergency drought incremental costs and maintenance expenses, unrealized gains on our benefit plan investments, and an increase resulting from the implementation of allowance for equity funds used during construction in 2017. These increases to net income were partially offset by increases in depreciation and amortization, interest, and employee wage expenses.

Operating Revenue

Operating revenue increased $19.0 million, or 6.9%, to $293.2 million in the first six months of 2017 as compared to the first six months of 2016. The factors that impacted the operating revenue for the first six months of 2017 as compared to 2016 are as follows:

28

Net change due to rate changes, usage, and other (1)	$	31,324
MCBA Revenue (2)	(5,622		)
Other balancing account revenue (3)	(2,626		)
Deferral of revenue (4)	(4,080		)
Net operating revenue increase	$	18,996

1. The net change due to rate changes, usage, and other in the above table was mainly driven by rate increases offset by a $0.7 million decrease in accrued unbilled revenue. The components of the rate increases are as follows:

General rate case	$	20,328
Purchased water and pump tax offset increases	7,358
Ratebase offset increases	1,016
Total increase in rates	$	28,702

2. The MCBA revenue decrease resulted from a decrease in customer consumption relative to adopted, which increased adopted water production costs relative to actual in the first six months of 2017 as compared to the first six months of 2016. As required by the MCBA mechanism, the increase in adopted water production costs relative to actual water production costs in California also decreased operating revenue for the same amount.

3. The other balancing account revenue consists of the pension, conservation and health care balancing account revenues. Pension and conservation balancing account revenues are the differences between actual expenses and adopted rate recovery. Health care balancing account revenue is 85% of the difference between actual health care expenses and adopted rate recovery. The decrease in revenue was mainly due to a decrease in actual health care and conservation expenses relative to adopted in the first six months of 2017 as compared to the first six months of 2016. This was partially offset by an increase in actual pension expenses relative to adopted in the first six months of 2017 as compared to the first six months of 2016.

4. The deferral of revenue consists of amounts that are expected to be collected from customers beyond 24 months following the end of the accounting period in which these revenues were recorded. The deferral increased in the first six months of 2017 as compared to the first six months of 2016 due to an increase in the balancing account revenue expected to be collected beyond 24 months.

Total Operating Expenses

Total operating expenses increased $10.5 million, or 4.2%, to $259.9 million in the first six months of 2017, as compared to $249.4 million in the first six months of 2016.

Water production costs consists of purchased water, purchased power, and pump taxes. It represents the largest component of total operating expenses, accounting for approximately 40.9% of total operating expenses in the first six months of 2017, as compared to 39.6% of total operating expenses in the first six months of 2016.  Water production costs increased 7.6% as compared to the same period last year mainly due to a blended 4.7% increase in purchased water wholesaler rates and an increase of 2.5% in purchased water production.

Sources of water as a percent of total water production are listed in the following table:

	Six Months Ended June 30
	2017		2016
Well production	48	%	48	%
Purchased	47	%	48	%
Surface	5	%	4	%
Total	100	%	100	%

29

The components of water production costs are shown in the table below:

	Six Months Ended June 30
	2017		2016		Change
Purchased water	$	87,690	$	81,439	$	6,251
Purchased power	12,509		11,868		641
Pump taxes	6,000		5,351		649
Total	$	106,199	$	98,658	$	7,541

Administrative and general and other operations expenses decreased $5.9 million, or 6.6%, to $83.5 million in the first six months of 2017, as compared to $89.4 million in the first six months of 2016. The decrease was due primarily to the deferral of MCBA costs of $3.6 million associated with the deferral of operating revenue and decreases in California drought program incremental costs of $2.8 million, health care benefit costs of $2.6 million, conservation program expenses of $1.1 million, and $0.5 million of insurance proceeds to recover most of the 2016 wild fire damages in our southern California District. The decreases were partially offset by employee wage cost increase of $1.5 million, pension benefit cost increase of $1.2 million, software maintenance and licensing cost increase of $0.8 million, and additional uninsured loss expenses of $0.7 million. Changes in employee pension and other postretirement benefit costs, water conservation program costs, and health care costs for regulated California operations do not affect net income, because the Company is allowed by the CPUC to track these costs in balancing accounts for future recovery, which create corresponding changes to operating revenue. 

Maintenance expense decreased $1.2 million, or 9.8%, to $10.8 million in the first six months of 2017, as compared to $12.0 million in the first six months of 2016, mostly due to increases in transmission and distribution mains repair costs.

Depreciation and amortization expense increased $6.5 million, or 20.5%, to $38.4 million in the first six months of 2017, as compared to $31.9 million in the first six months of 2016, mostly due to 2016 utility plant additions.

Income taxes increased $2.8 million, or 47.2%, to $8.8 million in the first six months of 2017, as compared to $5.9 million in the first six months of 2016. The increase was due primarily to an increase to operating income in the first six months of 2017 as compared to the first six months of 2016. 

Property and other taxes increased $0.7 million, or 6.0%, to $12.2 million during the first six months of 2017, as compared to $11.5 million in the first six months of 2016, due primarily to an increase in assessed property values in 2016 and increased local franchise taxes.

Other Income and Expenses

Net other income increased $2.3 million to $3.1 million in the first six months of 2017, as compared to $0.8 million in the first six months of 2016, due primarily to the implementation of allowance for equity funds used during construction in 2017 and a $0.9 million increase in unrealized gains on our benefit plan investments.

Interest Expense

Net interest expense increased $1.8 million, or 12.0%, to $16.7 million in the first six months of 2017, as compared to $14.9 million in the first six months of 2016. The increase was due primarily to an increase in short term financing for capital investments as well as increased short-term interest rates.

REGULATORY MATTERS

2017 California Regulatory Activity

California GRC filing

On December 15, 2016, the CPUC voted to approve Cal Water's 2015 GRC settlement agreement. The approved decision, which was proposed by the presiding Administrative Law Judge in November 2016, authorized Cal Water to increase gross revenue by approximately $45.0 million starting on January 1, 2017, up to $17.2 million in 2018, up to $16.3 million in 2019, and up to $30.0 million upon completion and approval of the Company’s advice letter projects. The 2018 and 2019 revenue increases are subject to the CPUC’s earning test protocol.

30

The CPUC’s decision also authorized Cal Water to invest $658.8 million in water system improvements throughout California over the three-year period of 2016-2018 in order to continue to provide safe and reliable water to its customers. This figure includes $197.3 million of water system infrastructure improvements that will be subject to the CPUC’s advice letter procedure.

Cost of Capital Application

In April of 2017, Cal Water, along with three other water utilities, filed an application to adopt a new cost of capital and capital structure for 2018. Cal Water requested a return on equity of 10.75% and a 53.4% equity capital structure as well as a water cost of capital adjustment mechanism similar to that last adopted for the company. The California Division of Ratepayer Advocates and other parties will submit testimony later in the year and may propose a different cost of capital and capital structure. The CPUC schedule for the application anticipates a decision on the matter by the end of 2017.

School Lead Testing Memorandum Account (SLT MA)

In March of 2017, Cal Water submitted an advice letter that established the SLT MA, which gives Cal Water the opportunity to recover costs related to lead monitoring and testing required by the State Water Resources Control Board's Division of Drinking Water. The SLT MA will track all incremental expenses associated with lead testing conducted at the request of K-12 schools within Cal Water's service territory.

California Drought Memorandum Account

The incremental costs tracked in the drought memorandum account for the six month period ended June 30, 2017 were $0.3 million, of which less than $0.1 million was spent on capital. For the six month period ended June 30, 2016, incremental costs were $3.8 million, of which $0.6 million was spent on capital. During three months ended June 30, 2017, incremental costs were $0.1 million, of which less than $0.1 million was spent on capital. During the three months ended June 30, 2016, incremental costs were $1.4 million, of which $0.2 million was spent on capital.

On December 15, 2016, the CPUC approved a resolution to allow Cal Water to begin recovering $2.9 million of incremental costs related to 2015 and 2014, through a surcharge, which became effective on January 1, 2017.

In 2017, Cal Water expects to submit an advice letter to request recovery of 2016 and 2017 incremental drought expenses and the incremental capital expenditures for the years 2015 and 2016.

WRAM and MCBA filings

In March of 2017, Cal Water submitted an advice letter to true up the revenue over- and under-collections in the 2016 annual WRAMs/MCBAs of its regulated districts. A net under-collection of $25.8 million is being recovered from customers in the form of 12, 18, and 18+ month surcharges/surcredits. The new rates became effective April 15, 2017.  This surcharge/surcredit in some cases is in addition to surcharges/surcredits authorized in prior years which have not yet expired.

Expense Offset filings

Expense offsets are dollar-for-dollar increases in revenue to match increased expenses, and therefore do not affect net operating income. In October of 2016, Cal Water submitted advice letters to offset increased purchased water and pump taxes in 4 of its regulated districts, totaling $1.9 million. The new rates became effective on January 1, 2017.

In March of 2017, Cal Water submitted an advice letter to offset increased purchased water in one of its regulated districts, totaling $1.0 million. The new rates became effective on April 15, 2017.

In June of 2017, Cal Water submitted advice letters to offset increased purchased water and pump taxes in four of its regulated districts, totaling $2.7 million. The new rates became effective on July 1, 2017.

In July of 2017, Cal Water submitted an advice letter to offset increased purchased water and pump taxes in one of its regulated districts, totaling $0.2 million. The new rates will become effective on August 1, 2017.

31

Ratebase Offset filings

For construction projects that are authorized in GRCs as advice letter projects, companies are allowed to file ratebase offsets to increase revenues after the plant is placed into service. In November of 2016, Cal Water submitted an advice letter to recover $2.6 million of annual revenue increase for ratebase offsets in five of its regulated districts. The new rates became effective on January 1, 2017.

In April of 2017, Cal Water submitted advice letters to recover $0.9 million of annual revenue increase for ratebase offsets in two of its regulated districts. The new rates became effective on April 15, 2017.

In May of 2017, Cal Water submitted an advice letter to recover $0.4 million of annual revenue increase for a ratebase offset in one of its regulated districts. The new rates became effective on July 1, 2017.

Travis Air Force Base

Cal Water has entered into a 50-year agreement with the U.S. Department of Defense to acquire the water distribution assets of, and to provide water utility service to, the Travis Air Force Base beginning in 2018. On May 31, 2017, Cal Water submitted an application to the CPUC seeking approval to provide water service to the base and to establish rates for its service.

The water system utilizes surface water treated at a water treatment plant and groundwater from five wells, and includes distribution piping, storage tanks, hydrants, and other appurtenances to serve about 15,280 active and reserve personnel and civilians on the 6,400-acre base. If approved, Cal Water will make initial capital improvements of about $12.7 million, with an anticipated capital investment of about $52.0 million over the 50-year term of the utility service contract.

2017 Regulatory Activity—Other States

2016 Pukalani (Hawaii) GRC Filing

In December of 2016, Hawaii water filed a GRC for its Pukalani wastewater system requesting an additional $1.3 million in revenues on an annual basis. This revenue increase is proposed to be implemented over five years. The application requested recovery for increases in operating expenses since the previous rate case. Additionally, the application requested recovery of the balance of the cost of the wastewater treatment plant that was not approved to be included in customer rates in the previous rate case among other capital investments. The first phase of the revenue increase is expected to become effective in the fourth quarter of 2017. Discovery between the parties is complete and settlement discussions are underway.

LIQUIDITY

Cash flow from Operations

Cash flow from operations for the first six months of 2017 was $35.7 million compared to $59.6 million for the same period in 2016. Cash generated by operations varies during the year due to customer billings, and timing of collections and contributions to our benefit plans.

During the first six months of 2017 we made contributions of $14.8 million to our employee pension plan compared to contributions of $14.0 million made during the first six months of 2016. During the first six months of 2017 there were no contributions to the other postretirement benefit plans compared to contributions of $3.3 million during the first six months of 2016. The total 2017 estimated cash contribution to the pension plans is $29.5 million and to the other postretirement benefit plans is $9.3 million.

Cal Water customer drought surcharges were discontinued on July 29, 2016. As such there were no drought surcharge billings during the first six months of 2017 as compared to $22.1 million in the first six months of 2016. In addition, Cal Water made $6.9 million prepayments for water chargesin the first six months of 2017, as compared to $4.2 million prepayment in the first six months of 2016.

The water business is seasonal. Billed revenue is lower in the cool, wet winter months when less water is used compared to the warm, dry summer months when water use is highest. This seasonality results in the possible need for short-term borrowings under the bank lines of credit in the event cash is not available to cover operating and utility plant costs during the winter period. The increase in cash flows during the summer allows short-term borrowings to be paid down. Customer

32

water usage can be lower than normal in drought years and when more than normal precipitation falls in our service areas or temperatures are lower than normal, especially in the summer months. In addition, short-term borrowings are used to finance utility plant expenditures until long-term financing is arranged.

Investing Activities

During the first six months of 2017 and 2016, we used $108.7 million and $116.2 million, respectively, of cash for utility plant expenditures. The 2017 budget estimates utility plant expenditures to be between $200.0 and $220.0 million. Annual expenditures fluctuate each year due to the availability of construction resources and our ability to obtain construction permits in a timely manner.

Financing Activities

Net cash provided by financing activities was $78.0 million during the first six months of 2017 compared to $79.8 million for the same period in 2016.

During the first six months of 2017 and 2016, we borrowed $140.0 million and $103.1 million, respectively, on our unsecured revolving credit facilities. Repayments of unsecured revolving credit facilities borrowings during the first six months of 2017 were $47.0 million and $61.6 million for the same period in 2016.

The undercollected net WRAM and MCBA receivable balances were $54.8 million and $28.9 million as of June 30, 2017 and June 30, 2016, respectively. The undercollected balances were primarily financed by Cal Water using short-term and long-term financing arrangements to meet operational cash requirements. Interest on the undercollected balances, the interest recoverable from ratepayers, is limited to the current 90-day commercial paper rates which is significantly lower than Cal Water’s short and long-term financing rates.

Short-Term and Long-Term Financing

During the first six months of 2017, we utilized cash generated from operations and borrowings on the unsecured revolving credit facilities. We did not sell Company common stock during the first six months of 2017 and 2016. In future periods, management anticipates funding our utility plant needs through a relatively balanced approach between long term debt and equity.

Short-term liquidity is provided by our unsecured revolving credit facilities and internally generated funds. Long-term financing is accomplished through the use of both debt and equity.  On September 23, 2010, the CPUC authorized Cal Water to issue $350.0 million of debt and common stock to finance utility plant projects and operations.

On March 10, 2015, the Company and Cal Water entered into Syndicated Credit Agreements, which provided for unsecured revolving credit facilities of up to an initial aggregate amount of $450.0 million for a term of five years. The Syndicated Credit Facilities amended, expanded, and replaced the Company’s and its subsidiaries’ credit facilities originally entered into on September 29, 2011. The new credit facilities extended the terms until March 10, 2020 and increased the Company’s unsecured revolving line of credit. The credit facilities may each be expanded by up to $50.0 million subject to certain conditions. 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.  On May 13, 2016, the CPUC approved additional financing for Cal Water. As part of that decision, Cal Water is now allowed to use its revolving credit facilities for up to 24 months. Previously, Cal Water had to pay down its credit facility every 12 months unless otherwise authorized by the CPUC. The proceeds from the revolving credit facilities may be used for working capital purposes, including the short-term financing of utility plant 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 capitalization ratio. Likewise, the unused commitment fee may vary from 8 basis points to 12.5 basis points based on the same ratio.

As of June 30, 2017, there were short-term borrowings of $190.1 million outstanding on the unsecured revolving credit facilities compared to $75.1 million as of June 30, 2016. The increase in short-term borrowings during the first six months of 2017 was mostly to fund general operations and capital investment.

Given our ability to access our lines of credit on a daily basis, cash balances are managed to levels required for daily cash needs and excess cash is invested in short-term or cash equivalent instruments. Minimal operating levels of cash are maintained for Washington Water, New Mexico Water, and Hawaii Water.

33

Both short-term 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 capitalization ratio not to exceed 66.7% and an interest coverage ratio of three or more.  As of June 30, 2017, we are in compliance with all of the covenant requirements and are eligible to use the full amount of our credit facilities.

In March 2016, Cal Water issued $50.0 million of First Mortgage Bonds, consisting of $40.0 million of 4.41% series SSS maturing April 16, 2046 and $10.0 million of 4.61% series TTT maturing April 14, 2056. Cash proceeds of approximately $49.7 million, net of $0.3 million debt issuance costs, were received. Cal Water used a portion of the net proceeds from the offering to repay outstanding borrowings on the Company and Cal Water lines of credit of $48.6 million.

Bond principal and other long-term debt payments were $2.4 million during the first six months of 2017 and $2.5 million during the first six months of 2016.

Long-term financing, which includes senior notes, other debt securities, and common stock, has typically been used to replace short-term borrowings and fund utility plant expenditures. Internally generated funds, after making dividend payments, provide positive cash flow, but have not been at a level to meet the needs of our utility plant expenditure requirements. Management expects this trend to continue given our utility plant expenditures plan for the next five years. Some utility plant expenditures are funded by payments received from developers for contributions in aid of construction or advances for construction. Funds received for contributions in aid of construction are non-refundable, whereas funds classified as advances in construction are refundable. Management believes long-term financing is available to meet our cash flow needs through issuances in both debt and equity instruments.

Dividends

During the first six months of 2017, our quarterly common stock dividend payments were $0.1800 per share compared to $0.1725 during the first six months of 2016. For the full year 2016, the payout ratio was 68% of net income. On a long-term basis, our goal is to achieve a dividend payout ratio of 60% of net income accomplished through future earnings growth.

At the July 26, 2017 meeting, the Board declared the second quarter dividend of $0.1800 per share payable on August 18, 2017, to stockholders of record on August 7, 2017. This was our 290th consecutive quarterly dividend.

2017 Financing Plan

We intend to fund our utility plant needs in future periods through a relatively balanced approach between long-term debt and equity. The Company and Cal Water have a syndicated unsecured revolving line of credit of $150.0 million and $300.0 million, respectively, for short-term borrowings. As of June 30, 2017, the Company’s and Cal Water’s availability on these unsecured revolving lines of credit was $94.9 million and $135.0 million, respectively.

Book Value and Stockholders of Record

Book value per common share was $13.78 at June 30, 2017 compared to $13.75 at December 31, 2016. There were approximately 1,960 stockholders of record for our common stock as of May 8, 2017.

Utility Plant Expenditures

During the first six months of 2017, utility plant expenditures totaled $108.7 million for company-funded and developer-funded projects. The 2017 budget estimates company-funded utility plant expenditures to be between $200.0 and $220.0 million. The actual amount may vary from the budget number due to timing of actual payments related to current year and prior year projects. We do not control third-party-funded utility plant expenditures and therefore are unable to estimate the amount of such projects for 2017.

As of June 30, 2017, construction work in progress was $167.9 million compared to $199.5 million as of June 30, 2016. Work in progress includes projects that are under construction but not yet complete and placed in service.

34

WATER SUPPLY

Our source of supply varies among our operating districts. Certain districts obtain all of their supply from wells; some districts purchase all of their supply from wholesale suppliers; and other districts obtain supply from a combination of wells and wholesale suppliers. A small portion of supply comes from surface sources and is processed through Company-owned water treatment plants. To the best of management’s knowledge, we are meeting water quality, environmental, and other regulatory standards for all company-owned systems.

Historically, approximately 49% of our annual water supply is pumped from wells. State groundwater management agencies operate differently in each state. Some of our wells extract ground water from water basins under state ordinances. These are adjudicated groundwater basins, in which a court has settled the dispute between landowners or other parties over how much annual groundwater can be extracted by each party. All of our adjudicated groundwater basins are located in the State of California. Our annual groundwater extraction from adjudicated groundwater basins approximates 6.8 billion gallons or 15% of our total annual water supply pumped from wells. Historically, we have extracted less than 100% of our annual adjudicated groundwater rights and have the right to carry forward up to 20% of the unused amount to the next annual period. All of our remaining wells extract ground water from managed or unmanaged water basins. There are no set limits for the ground water extracted from these water basins; however, the state or local water management agencies have the authority to regulate the groundwater extraction quantity whenever there are unforeseen large decreases to water basin levels. Our annual groundwater extraction from managed groundwater basins approximates 28.1 billion gallons or 59% of our total annual water supply pumped from wells. Our annual groundwater extraction from unmanaged groundwater basins approximates 12.2 billion gallons or 26% of our total annual water supply pumped from wells. Most of the managed groundwater basins we extract water from have groundwater recharge facilities. We are required to pay well pump taxes to financially support these groundwater recharge facilities. Our well pump taxes were $6.0 million and $5.4 million for the six months ended June 30, 2017 and 2016, respectively. Well pump taxes were $3.2 million and $2.9 million for the three months ended June 30, 2017 and 2016, respectively. In 2014, the State of California enacted the Sustainable Groundwater Management Act of 2014. The law and its implementing regulations will require most basins to select a sustainability agency by 2017, develop a sustainability plan by 2022, and show progress toward sustainability by 2027. We expect that in the future, groundwater will be produced mainly from managed and adjudicated basins.

California’s normal weather pattern yields little precipitation between mid-spring and mid-fall. The Washington Water service areas receive precipitation in all seasons, with the heaviest amounts during the winter. New Mexico Water’s rainfall is heaviest in the summer monsoon season. Hawaii Water receives precipitation throughout the year, with the largest amounts in the winter months. Water usage in all service areas is highest during the warm and dry summers and declines in the cool winter months. Rain and snow during the winter months replenish underground water aquifers and fill reservoirs, providing the water supply for subsequent delivery to customers. As of June 30, 2017, the State of California snowpack water content and rainfall accumulation during the 2016 - 2017 water year was 194% of normal (per the California Department of Water Resources, Northern Sierra Precipitation Accumulation report). On April 7, California's Governor Brown declared an end to the drought emergency in 54 of California’s 58 counties. Two of Cal Water's districts remain under a declared drought; these were areas where groundwater was impacted by five years of drought conditions. Management believes that supply pumped from underground aquifers and purchased from wholesale suppliers will be adequate to meet customer demand during 2017 and beyond. Long-term water supply plans are developed for each of our districts to help assure an adequate water supply under various operating and supply conditions. Some districts have unique challenges in meeting water quality standards, but management believes that supplies will meet current standards using current treatment processes.

CONTRACTUAL OBLIGATIONS

During the six months ended June 30, 2017, there were no material changes in contractual obligations outside the normal course of business.

Item 3.

QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

We do not hold, trade in or issue derivative financial instruments and therefore are not exposed to risks these instruments present. Our market risk to interest rate exposure is limited because the cost of long-term financing and short-term bank borrowings, including interest costs, is covered in consumer water rates as approved by the commissions. We do not have

35

foreign operations; therefore, we do not have a foreign currency exchange risk. Our business is sensitive to commodity prices and is most affected by changes in purchased water and purchased power costs.

Historically, the CPUC’s balancing account or offsetable expense procedures allowed for increases in purchased water and purchased power costs to be flowed through to consumers. Traditionally, a significant percentage of our net income and cash flows comes from California regulated operations; therefore the CPUC’s actions have a significant impact on our business. See Item 2, “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Regulatory Matters”.

Item 4.

CONTROLS AND PROCEDURES

(a) Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(c) under the Exchange Act) that are designed to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Securities and Exchange Commission’s rules and forms, and that such information is accumulated and communicated to our management, including our CEO and CFO, as appropriate, to allow for timely decisions regarding required disclosure.

In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Accordingly, our disclosure controls and procedures have been designed to provide reasonable assurance of achieving their objectives.

Our management, with the participation of our CEO and our CFO, evaluated the effectiveness of our disclosure controls and procedures as of June 30, 2017. Based on that evaluation, we concluded that our disclosure controls and procedures were effective at the reasonable assurance level.

(b) Changes to Internal Control over Financial Reporting

There was no change in our internal controls over financial reporting that occurred during the quarter ended June 30, 2017, that has materially affected, or is reasonably likely to materially affect, our internal controls over financial reporting.

PART II OTHER INFORMATION

Item 1.

LEGAL PROCEEDINGS

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. In the future, we may be involved in disputes and litigation related to a wide range of matters, including employment, construction, environmental issues and operations. Litigation can be time consuming and expensive and could divert management’s time and attention from our business. In addition, if we are subject to additional lawsuits or disputes, we might incur significant legal costs and it is uncertain whether we would be able to recover the legal costs from ratepayers or other third parties. For more information refer to footnote 10.

Item 1A.

RISK FACTORS

Organization and Operations and Basis of Presentation

Organization and Operations and Basis of Presentation

California Water Service Group (the 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 herein 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 unaudited condensed consolidated interim financial information has been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) for interim financial information and in accordance with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X promulgated by the Securities and Exchange Commission (SEC) and therefore do not contain all of the information and footnotes required by GAAP and the SEC for annual financial statements. The unaudited condensed consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements for the year ended December 31, 2016, included in its annual report on Form 10-K as filed with the SEC on February 23, 2017.

The preparation of the Company’s unaudited condensed consolidated interim 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 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, 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.

In the opinion of management, the accompanying unaudited condensed consolidated interim financial statements reflect all adjustments, consisting of normal recurring transactions that are necessary to provide a fair presentation of the results for the periods covered. The results for interim periods are not necessarily indicative of the results for any future period.

Due to the seasonal nature of the water business, the results for interim periods are not indicative of the results for a 12-month period. Revenue and income are generally higher in the warm, dry summer months when water usage and sales are greater. Revenue and income are generally lower in the winter months when cooler temperatures and rainfall curtail water usage and sales.

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 the 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 wastewater revenue requirements are authorized by the Commissions in the states in which they 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 California Public Utilities Commission (CPUC). Under the Water Revenue Adjustment Mechanism (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. 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 guidance for regulated operations. The variance amount represents amounts that will be billed or refunded to customers in the future. In addition to volumetric revenues, the revenue requirements approved by the CPUC include service charges, flat rate charges, and other items not subject to the WRAM.

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 Modified Cost Balancing Account (MCBA) provide 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 customers in the future. Cost-recovery expenses are generally recognized when expenses are incurred with no markup for return on investments 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 and the deferred net balances are interest bearing at the current 90 day commercial paper rate. Subsequent to calendar year-end, Cal Water files with the CPUC to refund or collect the balance in the accounts. The majority of under-collected net WRAM and MCBA receivable balances are collected over 12 or 18 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 period in which it was recorded. The deferred net WRAM and MCBA revenue and associated costs were determined using forecasts of customer consumption trends in future reporting periods and the estimated timing of when the CPUC will authorize Cal Water's filings to recover unbilled balances. Deferred revenues and associated costs are recorded in the periods when the 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 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 $0.8 million as of June 30, 2017 and December 31, 2016, respectively. This liability is included in “accrued expenses and other liabilities” on the condensed consolidated balance sheets.

Allowance for Funds Used During Construction

The allowance for funds used during construction (AFUDC) represents the capitalized cost of funds used to finance the construction of the utility plant. In general, AFUDC is applied to Cal Water construction projects requiring more than one month to complete. No AFUDC is applied to projects funded by customer advances for construction, contributions in aid of construction, or applicable state-revolving fund loans. AFUDC includes the net cost of borrowed funds and a rate of return on other funds when used, and is recovered through water rates as the utility plant is depreciated. Cal Water was authorized by the CPUC to record AFUDC on construction work in progress effective January 1, 2017. Prior to January 1, 2017, the CPUC authorized Cal Water to only record capitalized interest on borrowed funds. Cal Water previously reported the amounts authorized as capitalized interest and a reduction to interest expense. The amount of AFUDC related to equity funds and to borrowed funds for the three and six month periods ended June 30, 2017 and 2016 are shown in the tables below:

	Three Months Ended June 30
	2017		2016		Change

Cash and Cash Equivalents

Cash equivalents include highly liquid investments with maturities of three months or less.  Cash and cash equivalents was $29.1 million and $25.5 million as of June 30, 2017 and December 31, 2016, respectively.  Restricted cash was presented on the condensed consolidated balance sheet in “taxes, prepaid expenses and other assets” and was $1.0 million and $0.4 million as of June 30, 2017 and December 31, 2016, respectively.

Adoption of New Accounting Standards

In March 2016, the Financial Accounting Standards Board (FASB) issued updated accounting guidance on simplifying the accounting for share-based payments (ASU 2016-09), which includes the accounting for share-based payment transactions, the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The Company adopted and implemented the changes to accounting for share-based payments on January 1, 2017 and applied the requirements retrospectively on the statement of cash flows for all periods presented. The Company's forfeiture policy did not change and the Company continues to account for forfeitures when they occur. For the six month period ended June 30, 2016, the Company recorded $0.5 million of income tax benefits in excess of compensation costs for share-based compensation which reduced the effective tax rate. The tax-related cash flows resulting from share-based payments were reported as operating activities and the associated cash paid by the company for employee tax withholding transactions were reported as financing activities on the consolidated statement of cash flows.

The following table shows the effect of the accounting change to the Condensed Consolidated Statements of Cash Flows for the six month period ended June 30, 2016:

	Six Months Ended June 30, 2016
Cash Flow Classification	As Reported on Form 10-Q		Adjusted Balance on Form 10-Q			Increase (Decrease) from Retrospective Adoption
Other changes in noncurrent assets and liabilities	$	16,209	$	16,757		$	548

Repurchase of common stock	—		(548		)	(548		)
Net cash provided by financing activities	80,304		79,756			(548		)

New Accounting Standards

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which amends the existing revenue recognition guidance.  In August 2015, the FASB deferred 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 expects to adopt the new revenue standard using the modified retrospective method and does not expect the ASU to materially impact the timing or recognition of revenue related to the sale and delivery of water to their customers, which is a significant percentage of the Company's revenue. The Company is still evaluating the impact the ASU has on the related revenue disclosures.

In February 2016, the FASB issued ASU 2016-02, Leases. This update changes the accounting treatment of operating leases for lessees and related disclosure requirements. ASU 2016-02 is effective for annual reporting periods beginning after December 15, 2018 and early adoption is permitted. The Company will adopt the standard using the modified retrospective method for its existing leases and is currently evaluating the impact of adopting the new lease standard on its consolidated financial statements and related disclosures.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230) - Classification of Certain Cash Receipts and Cash Payments. This update adds and clarifies guidance on the classification of certain cash receipts and payments in the statement of cash flows. ASU 2016-15 is effective for annual periods beginning after December 15, 2017 and early adoption is permitted. The Company is currently evaluating the impact on its consolidated financial statements and related disclosures.

In March 2017, the FASB issued Accounting Standards Update No. 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost (“ASU 2017-07”). The update requires employers to present the service cost component of the net periodic benefit cost in the same income statement line item as other employee compensation costs arising from services rendered during the period. The other components of net benefit cost, including interest cost, expected return on plan assets, amortization of prior service cost/credit and actuarial gain/loss, and settlement and curtailment effects, are to be presented as non-operating items. Employers will have to disclose the line(s) used to present the other components of net periodic benefit cost, if the components are not presented separately in the income statement. The standard only allows the service cost component to be eligible for capitalization. ASU 2017-07 is effective for annual periods after December 15, 2017, and early adoption is permitted. The Company is currently evaluating the impact on its consolidated financial statements and related disclosures. The adoption of this guidance will change the Company's financial statement presentation of net benefit costs. However, based on current regulatory authorization, the changes required by the standard are not expected to materially impact the results of operations.

Earnings Per Share [Abstract]

Earnings Per Share

Earnings Per Share

The computations of basic and diluted earnings per share are noted below. Basic earnings per share is computed by dividing the net income available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts were exercised or converted into common stock. RSAs are included in the weighted average common shares outstanding because the shares have all the same voting and dividend rights as issued and unrestricted common stock. RSUs are not included in diluted shares for financial reporting until authorized by the Compensation & Organization Committee of the Board of Directors

There were no shares of Stock Appreciation Rights (SARs) outstanding as of June 30, 2017 and as of June 30, 2016. All the SARs were dilutive when they were outstanding during the period, as shown in the tables below.

Pension Plan and Other Postretirement Benefits

The Company provides a qualified, defined-benefit, non-contributory pension plan for substantially all employees. The Company makes annual contributions to fund the amounts accrued for in the qualified pension plan. The Company also maintains an unfunded, non-qualified, supplemental executive retirement plan. The costs of the plans are charged to expense or are capitalized in utility plant as appropriate.

The Company offers medical, dental, vision, and life insurance benefits for retirees and their spouses and dependents. Participants are required to pay a premium, which offsets a portion of the cost.

Cash contributions by the Company related to pension plans were $14.8 million and $14.0 million for the six months ended June 30, 2017 and June 30, 2016, respectively. There were no cash contributions by the Company to other postretirement benefit plans for the six months ended June 30, 2017 and $3.3 million of contributions for the six months ended June 30, 2016. The total 2017 estimated cash contribution to the pension plans is $29.5 million and to the other postretirement benefit plans is $9.3 million.

The following table lists components of net periodic benefit costs for the pension plans and other postretirement benefits.

Short-term and Long-term Borrowings

Short-term and Long-term Borrowings

In March 2016, Cal Water issued the remaining $50.0 million of First Mortgage Bonds, consisting of $40.0 million of 4.41% series SSS maturing April 16, 2046 and $10.0 million of 4.61% series TTT maturing April 14, 2056. Cash proceeds of approximately $49.7 million, net of $0.3 million debt issuance costs, were received. Cal Water used a portion of the net proceeds from the offering to repay outstanding borrowings on the Company and Cal Water lines of credit of $48.6 million.

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 capitalization ratio and interest coverage ratio.

The outstanding borrowings on the Company lines of credit were $55.1 million and $57.1 million as of June 30, 2017 and December 31, 2016, respectively. There were $135.0 million and $40.0 million borrowings on the Cal Water lines of credit as of June 30, 2017 and December 31, 2016, respectively.  The average borrowing rate for borrowings on the Company and Cal Water lines of credit during the six months ended June 30, 2017 was 1.82% compared to 1.30% for the same period last year.

Income Taxes

Income Taxes

The Company accounts for income taxes under the provisions of ASC 740, Accounting for Income Taxes. The Company adjusts its effective tax rate each quarter to be consistent with the estimated annual effective tax rate. The Company also records the tax effect of unusual or infrequently occurring discrete items.

The provision for income taxes consists of the following:

	Three Months Ended June 30
	2017		2016
Income tax provision	$	10,852	$	7,254

	Six Months Ended June 30
	2017		2016
Income tax provision	$	10,857	$	6,510

The increase in the income tax provision for three months ended June 30, 2017 as compared to the three months ended June 30, 2016 was due primarily to an increase in the Company’s earnings in 2017 as compared to 2016, which was partially offset by a $0.1 million tax benefit associated with the settlement of equity awards in 2017. 

The increase in the income tax provision for six months ended June 30, 2017 as compared to the six months ended June 30, 2016 was due primarily to an increase in the Company’s earnings in 2017 as compared to 2016, which was partially offset by a $0.5 million tax benefit associated with the settlement of equity awards in 2017. The Company’s fiscal year 2017 effective tax rate is estimated to be 37%.

As of June 30, 2017 and December 31, 2016, the Company had unrecognized tax benefits of approximately $10.2 million. Included in the balance of unrecognized tax benefits as of June 30, 2017 and December 31, 2016 is approximately $1.9 million of tax benefits that, if recognized, would result in an adjustment to the Company’s effective tax rate. The Company does not expect its unrecognized tax benefits to change significantly within the next 12 months.

Commitments

The Company has significant commitments to lease certain office spaces and water systems and to purchase water from water wholesalers. These commitments are described in Form 10-K for the year ended December 31, 2016. As of June 30, 2017, there were no significant changes from December 31, 2016.

Contingencies

Groundwater Contamination

The Company has undertaken litigation against third parties to recover past and anticipated costs related to groundwater 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 groundwater contamination litigation to be used first to pay transactional expenses, then to make ratepayers 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. As of June 30, 2017 and December 31, 2016, the Company recognized a liability of $6.2 million and $6.0 million, respectively, for known legal matters. 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, dependent on the nature of the settlement.

Fair Value of Financial Assets and Liabilities

Fair Value Disclosures [Abstract]

Fair Value of Financial Assets and Liabilities

Fair Value of Financial Assets and Liabilities

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 hierarchical 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 1.70%.

Advances for construction fair values were estimated using broker quotes from companies that frequently purchase these investments.

Accounting Policies [Abstract]

Revenue

Revenue

Revenue generally includes monthly cycle customer billings for regulated water and wastewater services at rates authorized by the 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 wastewater revenue requirements are authorized by the Commissions in the states in which they 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 California Public Utilities Commission (CPUC). Under the Water Revenue Adjustment Mechanism (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. 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 guidance for regulated operations. The variance amount represents amounts that will be billed or refunded to customers in the future. In addition to volumetric revenues, the revenue requirements approved by the CPUC include service charges, flat rate charges, and other items not subject to the WRAM.

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 Modified Cost Balancing Account (MCBA) provide 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 customers in the future. Cost-recovery expenses are generally recognized when expenses are incurred with no markup for return on investments 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 and the deferred net balances are interest bearing at the current 90 day commercial paper rate. Subsequent to calendar year-end, Cal Water files with the CPUC to refund or collect the balance in the accounts. The majority of under-collected net WRAM and MCBA receivable balances are collected over 12 or 18 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 period in which it was recorded. The deferred net WRAM and MCBA revenue and associated costs were determined using forecasts of customer consumption trends in future reporting periods and the estimated timing of when the CPUC will authorize Cal Water's filings to recover unbilled balances. Deferred revenues and associated costs are recorded in the periods when the 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 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 $0.8 million as of June 30, 2017 and December 31, 2016, respectively. This liability is included in “accrued expenses and other liabilities” on the condensed consolidated balance sheets.

Allowance for Funds Used During Construction

Allowance for Funds Used During Construction

The allowance for funds used during construction (AFUDC) represents the capitalized cost of funds used to finance the construction of the utility plant. In general, AFUDC is applied to Cal Water construction projects requiring more than one month to complete. No AFUDC is applied to projects funded by customer advances for construction, contributions in aid of construction, or applicable state-revolving fund loans. AFUDC includes the net cost of borrowed funds and a rate of return on other funds when used, and is recovered through water rates as the utility plant is depreciated. Cal Water was authorized by the CPUC to record AFUDC on construction work in progress effective January 1, 2017. Prior to January 1, 2017, the CPUC authorized Cal Water to only record capitalized interest on borrowed funds. Cal Water previously reported the amounts authorized as capitalized interest and a reduction to interest expense.

Cash and Cash Equivalents

Cash and Cash Equivalents

Cash equivalents include highly liquid investments with maturities of three months or less.  Cash and cash equivalents was $29.1 million and $25.5 million as of June 30, 2017 and December 31, 2016, respectively.  Restricted cash was presented on the condensed consolidated balance sheet in “taxes, prepaid expenses and other assets” and was $1.0 million and $0.4 million as of June 30, 2017 and December 31, 2016, respectively.

Adoption of New Accounting Standards

Adoption of New Accounting Standards

In March 2016, the Financial Accounting Standards Board (FASB) issued updated accounting guidance on simplifying the accounting for share-based payments (ASU 2016-09), which includes the accounting for share-based payment transactions, the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The Company adopted and implemented the changes to accounting for share-based payments on January 1, 2017 and applied the requirements retrospectively on the statement of cash flows for all periods presented. The Company's forfeiture policy did not change and the Company continues to account for forfeitures when they occur. For the six month period ended June 30, 2016, the Company recorded $0.5 million of income tax benefits in excess of compensation costs for share-based compensation which reduced the effective tax rate. The tax-related cash flows resulting from share-based payments were reported as operating activities and the associated cash paid by the company for employee tax withholding transactions were reported as financing activities on the consolidated statement of cash flows.

The following table shows the effect of the accounting change to the Condensed Consolidated Statements of Cash Flows for the six month period ended June 30, 2016:

	Six Months Ended June 30, 2016
Cash Flow Classification	As Reported on Form 10-Q		Adjusted Balance on Form 10-Q			Increase (Decrease) from Retrospective Adoption
Other changes in noncurrent assets and liabilities	$	16,209	$	16,757		$	548
Net cash provided by operating activities	59,063		59,611			548
Repurchase of common stock	—		(548		)	(548		)
Net cash provided by financing activities	80,304		79,756			(548		)

New Accounting Standards

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which amends the existing revenue recognition guidance.  In August 2015, the FASB deferred 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 expects to adopt the new revenue standard using the modified retrospective method and does not expect the ASU to materially impact the timing or recognition of revenue related to the sale and delivery of water to their customers, which is a significant percentage of the Company's revenue. The Company is still evaluating the impact the ASU has on the related revenue disclosures.

In February 2016, the FASB issued ASU 2016-02, Leases. This update changes the accounting treatment of operating leases for lessees and related disclosure requirements. ASU 2016-02 is effective for annual reporting periods beginning after December 15, 2018 and early adoption is permitted. The Company will adopt the standard using the modified retrospective method for its existing leases and is currently evaluating the impact of adopting the new lease standard on its consolidated financial statements and related disclosures.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230) - Classification of Certain Cash Receipts and Cash Payments. This update adds and clarifies guidance on the classification of certain cash receipts and payments in the statement of cash flows. ASU 2016-15 is effective for annual periods beginning after December 15, 2017 and early adoption is permitted. The Company is currently evaluating the impact on its consolidated financial statements and related disclosures.

In March 2017, the FASB issued Accounting Standards Update No. 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost (“ASU 2017-07”). The update requires employers to present the service cost component of the net periodic benefit cost in the same income statement line item as other employee compensation costs arising from services rendered during the period. The other components of net benefit cost, including interest cost, expected return on plan assets, amortization of prior service cost/credit and actuarial gain/loss, and settlement and curtailment effects, are to be presented as non-operating items. Employers will have to disclose the line(s) used to present the other components of net periodic benefit cost, if the components are not presented separately in the income statement. The standard only allows the service cost component to be eligible for capitalization. ASU 2017-07 is effective for annual periods after December 15, 2017, and early adoption is permitted. The Company is currently evaluating the impact on its consolidated financial statements and related disclosures. The adoption of this guidance will change the Company's financial statement presentation of net benefit costs. However, based on current regulatory authorization, the changes required by the standard are not expected to materially impact the results of operations.
