Notes to Unaudited Condensed Consolidated Financial Statements

March 31, ~~2017~~2018

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,~~2017, included in its annual report on Form 10-K as filed with the SEC on ~~February 23, 2017.~~March 1, 2018.

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

Operating revenue

~~Revenue~~The following table disaggregates the Company’s operating revenue by source:



	Three Months Ended March 31,
	2018			2017
Revenue from contracts with customers	$	134,254		$	112,812
Regulatory balancing account revenue	(2,007		)	9,224
Total operating revenue	$	132,247		$	122,036

Revenue ~~generally includes monthly cycle customer billings for~~from contracts with customers

The Company principally generates operating revenue from contracts with customers by providing 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~~tariff-rates authorized by the Commissions in the states in which they ~~operate.~~ operate and non-regulated water and wastewater services at rates authorized by contracts with government agencies. Revenue from contracts with customers reflects amounts billed for the volume of consumption at authorized per unit rates, for a service charge, and for other authorized charges.

The ~~revenue requirements are intended~~Company satisfies its performance obligation to provide water and wastewater services over time as services are rendered. The Company applies the ~~Company a reasonable opportunity to recover its operating costs~~invoice practical expedient and ~~earn a return on investments.~~

~~For metered customers, Cal Water~~ recognizes revenue from ~~rates~~contracts with customers in the amount for which the Company has a right to invoice. The Company has a right to invoice for the volume of consumption, for the service charge, and for other authorized charges.

The measurement of sales to customers is generally based on the reading of their meters, which occurs on a systematic basis throughout the month. At the end of each month, the Company estimates consumption since the date of the last meter reading and a corresponding unbilled revenue is recognized. The estimate is based upon the number of unbilled days that month and the average daily customer billing rate from the previous month (which fluctuates based upon customer usage).

Contract terms are ~~designed~~generally short-term and at will by customers and, as a result, no separate financing component is recognized for their collections from customers, which generally require payment within 30 days of billing. The Company applies judgment, based principally on historical payment experience, in estimating their customers’ ability to pay.

Certain customers are not billed for volumetric consumption, but are instead billed a flat rate at the beginning of each monthly service period. The amount billed is initially deferred and subsequently recognized over the monthly service period, as the performance obligation is satisfied. The deferred revenue balance, which is included in "other accrued liabilities" on the consolidated balance sheets, is inconsequential.

In the following table, revenue from contracts with customers is disaggregated by class of customers:



	Three Months Ended March 31,
	2018		2017
Residential	$	91,319	$	75,865
Business	27,057		22,026
Industrial	7,579		6,954
Public authorities	5,444		4,146
Other	2,855		3,821
Total revenue from contracts with customers	$	134,254	$	112,812

Regulatory balancing account revenue

The Company’s ability to recover revenue requirements authorized by the California Public Utilities Commission (CPUC)~~. Under~~ in its triennial General Rate Case (GRC), is decoupled from the volume of the sales. Regulatory balancing account revenue is revenue related to rate mechanisms authorized in California by the CPUC, which allow the Company to recover the authorized revenue and are not considered contracts with customers.

The Water Revenue Adjustment Mechanism (WRAM)~~, Cal Water records~~ allows the Company to recognize 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.~~revenues. 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.revenue.

~~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 the adopted ~~expense~~ levels of expenses 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~~program costs and certain other operating ~~expenses adopted by the CPUC.~~expenses. 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.regulatory balancing account revenue.

~~The balances in the~~Each district's WRAM and MCBA regulatory 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~~are allowed to be netted against one another. The Company recognizes regulatory balancing accountrevenues that have been authorized for rate recovery, are objectively determinable and probable of recovery, and are expected to be collected within 24 months. To 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 and 18 months. Cal Water defers net WRAM and MCBA operating revenues and associated costs whenever the net receivable balances areextent that regulatory balancing accountrevenue is estimated to be ~~collected more than~~collectible beyond 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 collectionrecognition 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 March 31, 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 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 reduced interest expense. The amount of AFUDC related to equity funds during the three months ended March 31, 2017 was $0.8 million and there was $0 million for the three months ended March 31, 2016. The amount of AFUDC related to borrowed funds for the three months ended March 31, 2017 was $0.5 million and the equivalent amount of capitalized interest on borrowed funds was $0.7 million for the three months ended March 31, 2016.

Non-regulated Revenue

~~Adoption~~



	Three Months Ended March 31,
	2018		2017
Operating and maintenance revenue	$	3,165	$	1,913
Other non-regulated revenue	743		1,042
Non-regulated revenue from contracts with customers	$	3,908	$	2,955
Lease revenue	$	511	$	507
Total non-regulated revenue	$	4,419	$	3,462

Operating and maintenance services are provided for water and wastewater systems owned by private companies and municipalities. The Company negotiates formal agreements with the customers, under which they provide operating, maintenance and customer billing services related to the customers’ water system. The formal agreements outline the fee schedule for the services provided. The agreements typically call for a fee-per-service or a flat-rate amount per month. The Company typically satisfies its performance obligation of ~~New Accounting Standard~~providing operating and maintenance services over time as services are rendered; as a result, the Company employs the invoice practical expedient and recognizes revenue in the amount that it has the right to invoice. Contract terms are generally short-term and as a result no separate financing component is recognized for its collections from customers, which generally require payment within 30 days of billing.

Other non-regulated revenue primarily relates to services for the design and installation of water mains and other water infrastructure for customers outside the regulated service areas and insurance program administration. Other non-regulated revenue is inconsequential.

~~In March 2016,~~The Company is the ~~Financial Accounting Standards Board (FASB) issued updated accounting guidance on simplifying the accounting for share-based payments (ASU 2016-09),~~lessor in operating lease agreements with telecommunications companies under which ~~includes the accounting for share-based payment transactions, the income tax consequences, classification of awards as either equity or liabilities, and classification~~cellular phone antennas are placed on the ~~statement of cash flows.

Cash, Cash Equivalents, 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 three month period ended March 31, 2017, the Company recorded $0.5 million of income tax benefits in excess 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.

Adoption of New Accounting Standards

In May of 2014, the FASB issued ASU ~~No.~~ 2014-09, Revenue from Contracts with Customers (codified in ASC 606), 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~~completed an evaluation of the new revenue standard ~~using~~and implemented 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 hasstandard 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,~~January 1, 2018 ~~and early adoption is permitted. The Company will adopt the standard~~ using the modified retrospective method for ~~its existing leases~~all contracts. The reported results for the first three months of 2018 reflect the application of ASC 606 guidance, while prior period amounts were not adjusted and ~~is currently evaluating~~continue to be reported in accordance with the accounting standards in effect for those periods. Other than increased disclosures regarding revenues related to contracts with customers, the implementation did not have a significant impact ~~of adopting~~on the ~~new lease standard on its~~Company’s consolidated financial statements ~~and related disclosures.~~(see "Operating Revenue" section of note 2 above).

In August of 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~~will continue to classify proceeds from the settlement of insurance claims on the basis of the nature of the loss and from the settlement of corporate-owned life insurance policies as cash inflows on the Condensed Consolidated Statements of Cash Flows. The Company implemented the standard on January 1, 2018 and retrospectively applied the standard in the comparative period. The standard does not have a significant impact ~~on its~~to the Company's consolidated financial ~~statements~~statements.

In November of 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230) - Restricted Cash. The update requires the Company to combine restricted cash with cash and ~~related disclosures.~~cash equivalents when reconciling the beginning and end

of period balances in the Condensed Consolidated Statements of Cash Flows. The Company implemented the standard on January 1, 2018 and retrospectively applied the standard in the comparative period.

The following table shows the effect of the accounting change to the Condensed Consolidated Statements of Cash Flows:



	Three Months Ended March 31, 2017

Cash, cash equivalents, and restricted cash at end of period	$	11,990		$	12,693		$	703

In March of 2017, the FASB issued ~~Accounting Standards Update No.~~ASU 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~~In addition, 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.

The standard became effective as of January 1, 2018. The presentation amendments were applied retrospectively and the capitalization amendments were applied prospectively on and after the effective date. The company applied the practical expedient that permits the Company to use the amounts disclosed in its pension and other postretirement benefit plan footnote from the prior comparative periods as the estimation basis for applying the retrospective presentation requirements. The Commissions have authorized the Company to recover the other components of net periodic benefit cost through the Company’s capital program and thus on and after the effective date, the other components of net periodic benefit cost that have previously been recorded as part of utility plant have been recognized as a regulatory asset (see note 9). As a result, the changes required by the standard did not have a material impact on the results of operations.

The following table shows the effect of the accounting change to the Condensed Consolidated Statements of (Loss) Income for the three months ended March 31, 2017:



	Three Months Ended March 31, 2017

New Accounting Standards Issued But Not Yet Adopted

In February of 2016, the FASB issued ASU ~~2017-07~~2016-02, Leases. This update changes the accounting treatment of leases and related disclosure requirements. In November of 2017, the FASB tentatively decided to amend the new leasing guidance such that entities may elect not to restate their comparative periods in the period of adoption. The guidance requires lessees to recognize an asset and liability on the balance sheet for all of their lease obligations. Operating leases were previously not recognized on the balance sheet. ASU 2016-02 is effective for annual reporting periods beginning after December 15, ~~2017,~~2018 and early adoption is permitted. The Company ~~is currently evaluating~~will adopt the standard using the modified retrospective method for its existing leases and expects this standard to increase lease assets and lease liabilities on the Condensed Consolidated Balance Sheets. The Company does not expect that the guidance will have a material impact on ~~its consolidated financial statements~~the Condensed Consolidated Statements of (Loss) Income, Condensed Consolidated Statements of Cash Flows, and ~~related~~lease 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.

Each RSU award reflects a target number of shares that may be issued to the award recipient. The ~~2017~~2018 and ~~2016~~2017 awards may be earned upon ~~the~~ completion of the three-year performance period and are recognized as expense ratably over the ~~three-year performance~~ period using a fair ~~market~~ value of ~~$36.75~~$35.40 per share and ~~$25.17~~$36.75 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 $0.7 million for the three months ended March 31, ~~2017~~2018 and ~~March 31, 2016.~~

Note 5. (Loss) Earnings Per Share

The computations of basic and diluted (loss) earnings per share are noted in the table below. Basic (loss) earnings per share isare computed by dividing the net (loss) 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 March 31, 2017 and as of March 31, 2016.~~

Note 7. Short-term and Long-term Borrowings

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.

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 as of March 31, ~~2017~~2018 and ~~$57.1 million as of~~ December 31, ~~2016.~~2017. There were ~~$75.0~~$220.0 million ~~and $40.0 million of~~ borrowings on the Cal Water lines of credit as of

March 31, ~~2017~~2018 and December 31, ~~2016, respectively.~~2017. The average borrowing rate for borrowings on the Company and Cal Water lines of credit during the three months ended March 31, ~~2017~~2018 was ~~1.6%~~2.45% compared to ~~1.27%~~1.60% 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:~~is shown below:

Three Months Ended March 31
2017 2016
Income tax provision (benefit) $ 5
$ (744 )



	Three Months Ended March 31
	2018			2017
Income tax (benefit) expense	$	(987	)	$	5

The ~~increase in the~~operating income tax ~~provision for 2017 from 2016 was due primarily~~benefit decreased $0.7 million to ~~an increase in the Company’s earnings~~$0.2 million for the three months ended March 31, 2018 as compared to the three months ended March 31, 2017 ~~which was partially offset by~~mostly due to a ~~$0.5~~decrease in the corporate federal income tax rate from 35 percent to 21 percent, effective January 1, 2018. The non-operating income tax expense decreased $1.6 million to $0.8 million for the three months ended March 31, 2018, as compared to the three months ended March 31, 2017, mostly due to a $1.5 million unrealized loss on certain benefit plan investments and a decrease in the corporate federal income tax ~~benefit associated with the settlement of equity awards.~~rate from 35 percent to 21 percent, effective January 1, 2018. The ~~Company’s fiscal year 2017~~Company's 2018 effective tax rate, before discrete items, is estimated to be ~~37%~~23%.

~~During the month of April~~For year ended December 31, 2017, the ~~Franchise Tax Board~~Company recorded a provisional re-measurement of ~~California completed an audit~~its deferred tax balances (related mostly to timing differences for plant-related items) which was offset by a change from a net deferred income tax regulatory asset to a net regulatory liability. The Company is continuing to work with state regulators to finalize the ratepayer net refund of $108.0 million to ensure compliance with federal normalization rules.

The final transition impacts of the ~~Company's State~~Tax Cuts and Jobs Act (TCJA) may differ from the recorded amounts, possibly materially, due to, among other things, regulatory decisions that could differ from the Company’s determination of ~~California EZ credit filing~~how the impacts of the TCJA are allocated between customers and shareholders. In addition, while the Company was able to make reasonable estimates of the impact of the reduction in federal tax rate and the elimination of bonus depreciation due to the enactment of the TCJA; the Company has not completed analysis for ~~years 2008-2012.~~areas of the TCJA around Internal Revenue Code Section 162(m), full expensing of fixed assets, and other asset related items of the TCJA. Changes in interpretations, guidance on legislative intent, and any changes in accounting standards for income taxes in response to the TCJA could impact the recorded amounts. The ~~completed audit~~Company will ~~not have a material~~finalize and record any adjustments related to the TCJA within the one year measurement period provided under Staff Accounting Bulletin No. 118. The balances relating to TCJA impact ~~on the Company's 2017 consolidated financial statements.~~

Ascontinue to be provisional as of March 31, ~~2017 and December 31, 2016, the~~2018.

The Company had unrecognized tax benefits of approximately $11.3 million and $10.5 ~~million.~~million as of March 31, 2018 and March 31, 2017, respectively. Included in the balance of unrecognized tax benefits as of March 31, 2018 and March 31, 2017 are approximately $2.1 million and ~~December 31, 2016 is approximately~~ $2.3 million, respectively, 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.

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 March 31, ~~2017~~2018 and December 31, ~~2016,~~2017, the Company recognized a liability of ~~$6.4~~$6.9 million and ~~$6.0~~$6.1 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.

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.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF

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. These statements are not statements of historical fact. When used in our documents, statements that are not historical in nature, including words like “expects,” “intends,” “plans,” “believes,” “may,” “estimates,” “assumes,” “anticipates,” “projects,” “predicts,” “forecasts,” “should,” “seeks,” or variations of these words or similar expressions are intended to identify forward-looking statements. 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;

changes in regulatory commissions’ policies and procedures;

the timeliness of regulatory commissions’ actions concerning rate relief;

inability to renew leases to operate city water systems on beneficial terms;

changes in California State Water Resources Control Board water quality standards;

changes in environmental compliance and water quality requirements;

electric power interruptions;

housing and customer growth trends;

the impact of opposition to rate increases;

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 ~~climate~~diseases on water quality, water availability, water sales and operating results;

~~the unknown impact of contagious diseases on the Company’s operations;~~

the risks set forth in “Risk Factors” included in the Company's annual report on ~~2016~~2017 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~~2017 Form 10-K. They include:

revenue recognition;

regulated utility accounting;

income taxes;

pension and postretirement health care benefits;

For the three month period ended March 31, ~~2017,~~2018, except for changes to revenue recognition from the adoption of ASC 606 (see Note 2), 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.

Overview

Net ~~income~~loss for the three month period ended March 31, ~~2017,~~2018, was ~~$1.1~~$2.5 million or ~~$0.02 earnings~~$0.05 net loss per diluted common share compared to a net ~~loss~~income of ~~$0.8~~$1.1 million or $0.02 ~~net loss~~earnings per diluted common share for the three month period ended March 31, ~~2016, an increase of $1.9 million.~~2017. The ~~increase~~$3.6 million decrease in net income was driven primarily by factors outside our immediate control, including a ~~result of rate increases and operating expenses decreases, notably a $1.8~~$1.5 million reduction in ~~California drought program incremental costs.~~unrealized income from certain benefit plan investments due to market conditions, a $0.8 million increase in uninsured loss costs due to water main breaks, and a $0.7 million reduction in unbilled revenue accrual. The ~~implementation~~net effect of ~~allowance for equity funds used during construction~~the following regulated revenue changes and ~~accounting changes for share-based payments, effective January 1, 2017,~~other operating costs also ~~increased net income. These increases were partially~~affected quarterly results. We received general rate relief of $4.7 million, offset by a ~~decrease~~reduction in rates due to the ~~accrual~~new adopted cost of capital for ~~unbilled revenue and increases~~Cal Water of $1.2 million, $1.5 million in additional depreciation and amortization costs, $0.7 million in additional wage costs, a $0.6 million increase in property and other taxes, and $0.5 million in additional interest expenses. ~~The change~~These cost increases were offset by a $0.7 million reduction in accrued unbilled revenue resulted mostly from a decrease in water usage. The change 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.

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~~increase in revenue was mainly due to ~~a decrease~~an increase in actual health care and pension expenses relative to adopted in the first quarter of 2018 as compared to the first quarter of ~~2016.~~2017, which was partially offset by a decrease in actual conservation expenses relative to adopted in the first quarter of 2018 as compared to the first quarter of 2017.

REGULATORY MATTERS

~~2017~~2018 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~~earnings test protocol.

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.

The CPUC follows a rate case plan, which requires Cal Water to file a GRC for each of its regulated operating districts (except Grand Oaks) every three years. In a GRC proceeding, the CPUC not only considers the utility's rate setting requests, but may also consider other issues that affect the utility's rates and operations. The CPUC is generally required to issue its GRC decision prior to the first day of the test year or authorize interim rates. In accordance with the rate case plan, Cal Water will file its next GRC application in July of 2018.

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. On March 22. 2018, the CPUC adopted a revised decision in the cost of capital proceeding for Cal Water ~~requested~~and three other water utilities for the years 2018-2020, establishing for Cal Water a 9.20% return on equity and a 5.51% cost of debt, with a capital structure of 46.60% long-term debt and 53.40% common equity, and an authorized return on rate base of 7.48%, compared with Cal Water’s prior return on equity of ~~10.75%~~9.43%, cost of debt of 6.24%, and ~~a 53.4% equity~~authorized return on rate base of 7.94%. The adopted capital structure ~~as well as a water~~did not change. The adopted returns on debt and

equity will reduce Cal Water’s 2018 adopted revenue by approximately $6.7 million. The CPUC also authorized continuation of the WCCM, which provides for an adjustment in the return on equity if the cost of ~~capital adjustment mechanism similar to that last adopted for~~long-term debt as defined by an index of utility debt rates varies from the ~~company. The California Division of Ratepayer Advocates~~most recent index by 100 basis points or more in 2019 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 2017.2020.

~~School Lead Testing Memorandum Account (SLT MA)~~

InOn March ~~of 2017,~~30, 2018, Cal Water submitted an advice letter that established the ~~SLT MA, which gives~~Cost of Capital Memorandum Account (CoC MA) to track the difference between current rates and rates based upon the new cost of capital adopted by the CPUC as if the new cost of capital had been in effect beginning January 1, 2018. For the first three months of 2018, Cal Water recorded a $1.2 million reduction to revenue with a corresponding regulatory liability due to 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.CoC MA.

~~California Drought~~2018 Tax Accounting Memorandum Account (TAMA)

~~The incremental costs tracked in~~On December 22, 2017, the drought memorandum account for the three month period ended March 31, 2017 were $0.2 million, of which less than $0.1 million was spent on capital. For the three month period ended March 31, 2016, incremental costs were $2.4 million, of which $0.4 million was spent on capital. On July 15, 2016, Cal Water submitted an adviceCPUC sent a letter to ~~recover $4.2 million~~All Class A and B Water and Sewer Utilities on the subject of incremental drought expenses associated with calendar years 2014 and 2015. During the third quarter of 2016, Cal Water discussed the request with interested parties, including the ORA. A revised advice letter was submitted on October 12, 2016 by“Changes in Federal Tax Rates for 2018.” The CPUC required Cal Water to ~~recover $2.9 million~~establish a memo account to track the impact of the TCJA on Cal Water. The TAMA will track the revenue requirement impact of the TCJA not otherwise reflected in ~~incremental costs related~~rates from January 1, 2018 until current rates are modified to ~~2014 and 2015 expenses. On December 15, 2016,~~reflect all impacts of the ~~CPUC approved a resolution to allow~~TCJA. For the first three months of 2018, Cal Water recorded a $1.9 million reduction to ~~begin recovering~~revenue with a corresponding regulatory liability due to the ~~requested $2.9~~TAMA. The Hawaii Water, Washington Water, and New Mexico Water Commissions have similar requirements to track the impact of the changes to the federal tax law. For the first three months of 2018, the Company recorded a reduction to revenue for $0.1 million ~~through~~for Hawaii Water, Washington Water and New Mexico Water.

Escalation increase requests

As a ~~surcharge, which became effective January 1, 2017.~~

part of the decision on the 2015 GRC, Cal Water was authorized to request annual escalation rate increases for 2018 for those districts that passed the earnings test. In November of 2017, Cal Water ~~expects to submit an advice letter to request recovery for~~requested escalation rate increases in all of its regulated districts. The annual adopted gross revenue associated with the ~~incremental drought expenses from 2016~~November 2017 ~~and the incremental capital expenditures from 2015-2016.~~

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,~~2017, Cal Water submitted an advice letter to recover ~~$2.6~~$1.4 million of annual revenue increase for ~~ratebase offsets~~a rate base offset in ~~five~~one of its regulated districts.

LIQUIDITY

Cash flow from Operations

Cash flow from operations for the first three months of ~~2017~~2018 was ~~$14.3~~$28.3 million compared to ~~$31.5~~$14.3 million for the same period in ~~2016.~~2017. 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 three months of ~~2017~~2018, we made contributions of ~~$7.5~~$7.3 million to our employee pension plan compared to contributions of ~~$7.3~~$7.5 million made during the first three months of ~~2016. There were no~~2017. During the first three months of 2018 and 2017, we did not make any contributions ~~made~~ to the other postretirement benefit ~~plans during the first three months of 2017 and 2016.~~plans. The ~~2017~~total 2018 estimated cash contribution to the pension plans is ~~$29.5~~$33.4 million and to the other postretirement benefit plans is ~~$9.3~~$10.1 million.

Cal Water customer drought surcharges were discontinued on July 29, 2016. As such there were no drought surcharge billings during the first quarter of 2017 as compared to $11.5 million in the first quarter of 2016. In addition, Cal Water made $6.6 million of prepayments for water charges and property taxes in the first quarter of 2017, as compared to none in the first quarter 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 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 three months of ~~2017~~2018 and ~~2016,~~2017, we used ~~$51.9~~$70.7 million and ~~$56.5~~$51.9 million, respectively, of cash for company-funded and developer-funded utility plant expenditures. The ~~2017~~2018 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~~used by financing activities was ~~$24.7~~$17.6 million during the first three months of ~~2017~~2018 compared to ~~$47.9~~$24.7 million of net cash provided by financing activities for the same period in ~~2016.~~2017.

During the first three months of ~~2017~~2018 and ~~2016,~~2017, we borrowed ~~$35.0~~$45.0 million and ~~$54.5~~$35.0 million, respectively, on our unsecured revolving credit facilities. Repayments of unsecured revolving credit facilities borrowings during the first three months of ~~2017~~2018 were ~~$2.0~~$45.0 million and ~~$53.6~~$2.0 million for the same period in ~~2016.~~2017. We also repaid $10.0 million of First Mortgage Bonds that matured in the first quarter of 2018.

The undercollected net WRAM and MCBA receivable balances were ~~$48.0~~$68.2 million and ~~$33.6~~$48.0 million as of March 31, ~~2017~~2018 and March 31, ~~2016,~~2017, 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~~Short-term and Long-Term Financing

During the first three months of ~~2017,~~2018, we utilized cash generated from operations and borrowings on the unsecured revolving credit facilities to fund operations and ~~proceeds from the issuance of long-term debt.~~capital investments. We did not sell Company common stock during the

first three months of ~~2017~~2018 and ~~2016.~~2017. 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~~facility; however, all borrowings need to ~~use its revolving credit facilities for up to~~be repaid within 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 March 31, 2018 and December 31, 2017, there were short-term borrowings of ~~$130.1~~$275.1 million outstanding on the unsecured revolving credit ~~facilities compared to $97.1 million as of December 31, 2016. The increase in short-term borrowings during the first three months of 2017 was mostly to fund general operations and capital investment.~~facilities.

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.

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 March 31, ~~2017,~~2018, we are in compliance with all of the covenant requirements and are eligible to use the full amount of our credit facilities.

Bond principal and other long-term debt payments were $10.2 million during the first three months of 2018 and $0.3 million during the first three months of ~~2017 and the first three months of 2016.~~2017.

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 three months of ~~2017,~~2018, our quarterly common stock dividend payments were ~~$0.18~~$0.1875 per share compared to ~~$0.1725~~$0.1800 during the first three months of ~~2016.~~2017. For the full year ~~2016,~~2017, the payout ratio was ~~68%~~51% 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 April ~~26, 2017~~25, 2018 meeting, the Board declared the ~~first~~second quarter dividend of ~~$0.18~~$0.1875 per share payable on May ~~19, 2017,~~18, 2018, to stockholders of record on May ~~8, 2017.~~7, 2018. This was our ~~289th~~294th consecutive quarterly dividend.

~~2017~~2018 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 March 31, ~~2017,~~2018, the Company’s and Cal Water’s availability on these unsecured revolving lines of credit was $94.9 million and ~~$225.0~~$80.0 million, respectively.

Book value per common share was ~~$13.56~~$14.17 at March 31, ~~2017~~2018 compared to ~~$13.75~~$14.44 at December 31, ~~2016.~~2017. There were approximately ~~1,118~~1,934 stockholders of record for our common stock as of February ~~6, 2017.~~12, 2018.

Utility Plant Expenditures

During the first three months of ~~2017,~~2018, utility plant expenditures totaled ~~$51.9~~$70.7 million for company-funded and developer-funded projects. The ~~2017~~2018 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.~~

2018.

As of March 31, ~~2017,~~2018, construction work in progress was ~~$150.5~~$197.4 million compared to ~~$171.9~~$150.5 million as of March 31, ~~2016.~~2017. Work in progress includes projects that are under construction but not yet complete and placed in service.

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~~management's knowledge, we are meeting water quality, environmental, and other regulatory standards for all ~~company-owned~~Company-owned systems.

Historically, approximately ~~49%~~46.5% 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%~~14.4% 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.~~basins. Our annual groundwater extraction from managed groundwater basins approximates ~~28.1~~28.0 billion gallons or ~~59%~~58.9% of our total annual water supply pumped from wells. Our annual groundwater extraction from unmanaged groundwater basins approximates ~~12.2~~12.7 billion gallons or ~~26%~~26.7% 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~~Well pump taxes were ~~$2.8~~$3.6 million and ~~$2.5~~$2.8 million for the three months ended March 31, ~~2017~~2018 and ~~2016,~~2017, 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~~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~~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 in California replenish underground water aquifers and fill reservoirs, providing the water supply for subsequent delivery to customers. As of March ~~31, 2017,~~30, 2018, the State of California snowpack water content ~~and rainfall accumulation~~ during the ~~2016 - 2017~~2017-2018 water year ~~was 167%~~is 57% of ~~normal~~long-term averages (per the California

Department of Water Resources, Northern Sierra Precipitation Accumulation report). The northern Sierra region is the most important for the state’s urban water supplies. The central and southern portions of the Sierras also have recorded 64% and 55%, respectively, of long-term averages. In January of 2014, California's Governor Brown proclaimed a drought emergency and directed State officials to take all necessary actions to make water immediately available. On April 7, ~~California's~~2017, the 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~~2018 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 three months ended March 31, ~~2017,~~2018, 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 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~~offsettable expense procedures allowed for increases in purchased water, pump tax, and purchased power costs to be flowed through to consumers. Traditionally, a significant percentage of our net income and cash flows ~~comes~~come 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”.~~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 March 31, ~~2017.~~2018. 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 March 31, ~~2017,~~2018, 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

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~~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 ~~Note~~footnote 10.

Item 1A.

RISK FACTORS

There have been no material changes to the Company’s risk factors set forth in Part I, Item 1A of the Company’s Annual Report on Form 10-K for the year-ended December 31, ~~2016~~2017 filed with the SEC on ~~February 23, 2017.~~March 1, 2018.

Item 5.

OTHER INFORMATION
