Notes to Unaudited Condensed Consolidated Financial Statements
March 31, 2019
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, 2018, included in its annual report on Form 10-K as filed with the SEC on February 28, 2019.
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.
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

Table of Contents
Revenue from contracts with customers
The Company principally generates operating revenue from contracts with customers by providing regulated water and wastewater services at tariff-rates authorized by the Commissions in the states in which they 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 Company satisfies its performance obligation to provide water and wastewater services over time as services are rendered. The Company applies the invoice practical expedient and recognizes revenue from 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 generally short-term and at will by customers and, as a result, no separate financing component is recognized for the Company's collections from customers, which generally require payment within 30 days of billing. The Company applies judgment, based principally on historical payment experience, in estimating its 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 or contract liability, which is included in "accrued expenses and other liabilities" on the consolidated balance sheets, is inconsequential.
In the following table, revenue from contracts with customers is disaggregated by class of customers for the three months ended March 31, 2019 and 2018:

| Three Months Ended March 31
| 2019 |  | 2018
Residential | $ | 84,259 |  |  | $ | 91,319 |
Business | 25,481 |  |  | 27,057 |
Industrial | 7,264 |  |  | 7,579 |
Public authorities | 4,471 |  |  | 5,444 |
Other (a) | (4,065 | ) |  | 2,855 |
Total revenue from contracts with customers | $ | 117,410 |  |  | $ | 134,254 |

(a) Other includes the accrued unbilled revenue.

Regulatory balancing account revenue
The Company’s ability to recover revenue requirements authorized by the California Public Utilities Commission (CPUC) 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) allows the Company to recognize the adopted level of volumetric revenues. The variance between adopted volumetric revenues and actual billed volumetric revenues for metered accounts is recorded as regulatory balancing account revenue.
Cost-recovery rates, such as the Modified Cost Balancing Account (MCBA), provide for recovery of the adopted levels of expenses for purchased water, purchased power, pump taxes, water conservation program costs, pension, and health care. Variances between adopted and actual costs are recorded as regulatory balancing account revenue.
Each district's WRAM and MCBA regulatory assets and liabilities are allowed to be netted against one another. The Company recognizes regulatory balancing account revenues 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 extent that regulatory balancing account revenue is estimated to be collectible beyond 24 months, recognition is deferred.

Non-regulated Revenue
The following table disaggregates the Company’s non-regulated revenue by source for the three months ended March 31, 2019 and 2018:

| Three Months Ended March 31
| 2019 |  | 2018
Operating and maintenance revenue | $ | 3,046 |  |  | $ | 3,165 |
Other non-regulated revenue | 1,296 |  |  | 743 |
Non-regulated revenue from contracts with customers | $ | 4,342 |  |  | $ | 3,908 |
Lease revenue | $ | 559 |  |  | $ | 511 |
Total non-regulated revenue | $ | 4,901 |  |  | $ | 4,419 |

Operating and maintenance services are provided for non-regulated 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 satisfies its performance obligation of 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.
Lease revenue is not considered revenue from contracts with customers and is recognized following operating lease standards. The Company is the lessor in operating lease agreements with telecommunications companies under which cellular phone antennas are placed on the Company's property. The company provides the lessee the right to ingress and egress across lessor property to access the Land. The minimum rents are recognized on a straight-line basis over the terms of the leases, which may span multiple years. The excess rents are recognized over amounts contractually due pursuant to the underlying leases and is included in a deferred receivable account in the accompanying balance sheet. The leases generally have terms of 5 years to 10 years, with lessee options to extend the lease for up to 15 years. The exercise of lease renewal options is at the lessee’s sole discretion. Most of the Company’s lease agreements contain mutual termination options that require prior written notice by either lessee or lessor to be invoked. A subset of the Company’s leases contains variable lease payments that depend on changes in the consumer price index (CPI).
The Company determines if an arrangement is a lease at inception. Generally, a lease agreement exists if the Company determines that the arrangement gives the lessee control over the use of an identified asset and obtains substantially all of the benefits from the identified asset.
Maturities of lease payments to be received are as follows:

Year Ending December 31, | Operating Leases
2019 | $ | 3,032 |
2020 | 2,482 |
2021 | 1,809 |
2022 | 1,013 |
2023 | 534 |
Thereafter | 828 |

Total cash, cash equivalents, and restricted cash shown in the statements of cash flows | $ | 60,890 |  |  | $ | 47,715 |

Adoption of New Accounting Standards
In February of 2016, the FASB issued guidance on leases, with amendments in 2018. 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.
The Company adopted the standard using the modified retrospective method for its existing leases and did not restate its comparative periods in the period of adoption. The Company completed its review of its lease portfolio including significant leases and the Company designed and implemented new controls as part of the adoption of the new standard. The implementation increased lease assets and lease liabilities on the Consolidated Balance Sheets by $13.8 million as of January 1, 2019.
The Company elected certain practical expedients and carried forward historical conclusions related to (1) contracts that contain leases, (2) existing lease classification for any expired or existing leases, and (3) initial direct costs for any existing leases. The Company also applied the practical expedient that allows the Company to elect, as an accounting policy, by asset class, to include both lease and nonlease components as a single component and account for it as a lease. The Company applied the short-term lease exception for lessees which allowed the Company to not have to apply the recognition requirements of the new leasing guidance for short-term leases and to recognize lease payments in net income on a straight line basis over the lease term. Otherwise, the new standard did not have a material impact on the remaining consolidated financial statements.
Note 3. Stock-based Compensation
Equity Incentive Plan
During the three months ended March 31, 2019 and 2018, the Company granted annual Restricted Stock Awards (RSAs) of 36,183 and 46,135, respectively, to officers and directors of the Company. During those same periods, 8,334 RSAs and 9,464 RSAs, respectively, were canceled. RSAs granted to officers vest over 36 months with the first year cliff vesting. RSAs granted to directors generally vest at the end of 12 months. During the first three months of 2019 and 2018, the RSAs granted were valued at $52.83 and $35.40 per share, respectively, based upon the fair value of the Company’s common stock on the date of grant.
During the three months ended March 31, 2019 and 2018, the Company granted 26,473 and 28,594 performance-based Restricted Stock Unit Awards (RSUs), respectively, to officers. During those same periods, the Company issued 62,726 RSUs and 48,753 RSUs, respectively, to officers, and canceled 31,177 RSUs and 24,009 RSUs, respectively. Each RSU award reflects a target number of shares that may be issued to the award recipient. The 2019 and 2018 awards may be earned upon completion of the three-year performance period and are recognized as expense ratably over the period using a fair value of $52.83 per share and $35.40 per share, respectively, and an estimate of RSUs earned during the period. The Company has recorded compensation costs for the RSAs and RSUs in administrative and general operating expenses in the amount of $2.7 million and $0.7 million for the three months ended March 31, 2019 and 2018, respectively.

Note 5. Loss Per Share
The computations of basic and diluted loss per share are noted in the table below. Basic loss per share are computed by dividing the net loss available to common stockholders by the weighted average number of common shares outstanding during the period. 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 Organization & Compensation Committee of the Board of Directors.

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.
There were no cash contributions made to the pension plans for the three months ended March 31, 2019 and there were cash contributions of $7.3 million made to the pension plans for the three months ended March 31, 2018. Cash contributions made by the Company related to other postretirement benefit plans were $1.4 million for the three months ended March 31, 2019 and there were no cash contributions made by the Company related to other postretirement benefit plans for the three months ended March 31, 2018. The total 2019 estimated cash contribution to the pension plans is $18.8 million and to the other postretirement benefit plans is $7.9 million.
The following table lists components of net periodic benefit costs for the pension plans and other postretirement benefits.

Note 7. Short-term and Long-term Borrowings
On March 29, 2019, the Company and Cal Water entered into certain syndicated credit agreements, which provide for unsecured revolving credit facilities of up to an initial aggregate amount of $550 million for a term of five years. The revolving credit facilities amend, expand, and replace the Company’s and its subsidiaries’ prior credit facilities originally entered into on May 10, 2015. The new credit facilities extended the terms until March 29, 2024, and increased Cal Water’s unsecured revolving line of credit. The Company and subsidiaries that it designates may borrow up to $150 million under the Company’s revolving credit facility. Cal Water may borrow up to $400 million under its revolving credit facility; however, all borrowings must be repaid within 24 months unless a different period is required or authorized by the CPUC. Additionally, the credit facilities available to the Company may be increased by up to an incremental $150 million under the Cal Water facility and $50 million under the Company facility, subject in each case to certain conditions. The proceeds from the revolving credit facilities may be used for working capital purposes, including the short-term financing of capital projects. Borrowings under the credit facilities typically have maturities varying between one and six months and will bear interest annually at a rate equal to (i) the base rate or (ii) the Eurodollar rate, plus an applicable margin of 0.650% to 0.875%, depending on the Company and its subsidiaries’ consolidated total capitalization ratio.
Both short-term unsecured credit agreements contain affirmative and negative covenants and events of default customary for credit facilities of this type including, among other things, limitations and prohibitions relating to additional

indebtedness, liens, mergers, and asset sales. Also, these unsecured credit agreements contain financial covenants governing the Company and its subsidiaries’ consolidated total capitalization ratio and interest coverage ratio.
The outstanding borrowings on the Company line of credit were $55.1 million as of March 31, 2019 and December 31, 2018. There were $70.0 million and $10.0 million of borrowings on the Cal Water line of credit as of March 31, 2019 and December 31, 2018, respectively. The average borrowing rate for borrowings on the Company and Cal Water lines of credit during the three months ended March 31, 2019 was 3.22% compared to 2.45% for the same period last year.
Note 8. 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 is shown in the tables below:

| Three Months Ended March 31
| 2019 |  | 2018
Income tax benefit | $ | (2,163 | ) |  | $ | (464 | )

The income tax benefit increased $1.7 million to $2.2 million for the three months ended March 31, 2019 as compared to the three months ended March 31, 2018. The increase is mostly due to an increase in pre-tax loss of $8.6 million for the three months ended March 31, 2019 as compared to the three months ended March 31, 2018.
The Company's 2019 effective tax rate, before discrete items, is estimated to be 22%.
For the year ended December 31, 2018, the Company recorded a re-measurement of its deferred tax balances (related mostly to timing differences for plant-related items). The final impact of the Tax Cuts and Jobs Act (TCJA) may differ from the recorded amounts, possibly materially, due to regulatory decisions that could differ from the Company’s determination of how the impact of the TCJA are allocated between customers and shareholders. In addition, changes in interpretations, guidance on legislative intent, and any changes in accounting standards for income taxes in response to the TCJA could also impact the recorded amounts.
The Company is continuing to work with state regulators to finalize the customer net refund of $107.0 million to ensure compliance with federal normalization rules and will record any adjustments based on state regulator decision.
The Company had unrecognized tax benefits of approximately $10.1 million and $8.0 million as of March 31, 2019 and 2018, respectively. Included in the balance of unrecognized tax benefits as of March 31, 2019 and 2018 are approximately $3.0 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 10. Commitments and Contingencies
Commitments
The Company has significant commitments purchase water from water wholesalers. These commitments are described in Form 10-K for the year ended December 31, 2018.
Leases
The Company has operating and finance leases for water systems, offices, land easements, licenses, equipment, and other facilities. The leases generally have remaining lease terms of 1 year to 50 years, some of which include options to extend the lease for up to 25 years. The exercise of lease renewal options is at the Company’s sole discretion. Most of the Company’s lease agreements contain mutual termination options that require prior written notice by either lessee or lessor to be invoked. The Company’s lease agreements do not contain any material residual value guarantees or material restrictive covenants. Certain leases include options to purchase the leased property. The depreciable life of the assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise. Leases with an initial term of 12 months or less are not recorded on the balance sheet as the Company applied the short-term lease exception allowed by the lease standard. Lease expense for these leases are recognized on a straight-line basis over the lease term. A subset of the Company’s leases contains variable lease payments that depend on changes in the CPI.
The Company determines if an arrangement is a lease at inception. Generally, a lease agreement exists if the Company determines that the arrangement gives the Company control over the use of an identified asset and obtains substantially all of the benefits from the identified asset.
The right-of-use (ROU) assets that are recorded represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of the Company’s operating leases do not provide an implicit rate, the Company uses an incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The ROU asset and lease liability may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Variable lease payments that are based on changes in CPI are included in the measurement of ROU asset and lease liability on the basis of the rate at lease commencement. Subsequent changes to the payments as a result of changes to the CPI rate are recognized in the period in which the obligation of these payments is incurred.

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 customers whole for water treatment costs to comply with the CPUC’s water quality standards. The CPUC allows for a risk-based consideration of contamination proceeds which exceed the costs of the remediation described above and may result in some sharing of proceeds with the shareholder, determined on a case by case basis. The CPUC has authorized various memorandum accounts that allow the Company to track significant litigation costs to request recovery of these costs in future filings and uses of proceeds to comply with CPUC’s general policy.

Other Legal Matters
From time to time, the Company is involved in various disputes and litigation matters that arise in the ordinary course of business. The status of each significant matter is reviewed and assessed for potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and the amount of the range of loss can be estimated, a liability is accrued for the estimated loss in accordance with the accounting standards for contingencies. Legal proceedings are subject to uncertainties, and the outcomes are difficult to predict. Because of such uncertainties, accruals are based on the best information available at the time. While the outcome of these disputes and litigation matters cannot be predicted with any certainty, management does not believe when taking into account existing reserves the ultimate resolution of these matters will materially affect the Company’s financial position, results of operations, or cash flows. As of March 31, 2019 and December 31, 2018, the Company recognized a liability of $3.2 million and $2.3 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.

Note 13. Immaterial Restatement of Prior Period Financial Statements
Subsequent to the issuance of the Company's Condensed Consolidated Financial Statements for the quarter ended March 31, 2018, the Company identified an immaterial computational error related to the amount of authorized revenue recorded pursuant to the Company's pension and health care cost recovery balancing accounts. In accordance with the 2015 GRC, the Company adjusts the revenue and corresponding balancing accounts quarterly to reflect actual pension and health care costs, subject to certain limitations prescribed by the 2015 GRC. The error does not impact the billings to customers or the cash collected from customers in this GRC period, which ends on December 31, 2019. As provided for in the 2015 GRC, the amounts included in the balancing account will be recovered from or refunded to customers during the next GRC period.
The Company corrected the error in the accompanying Condensed Consolidated Financial Statements for the three months ended March 31, 2018. The Company believes the correction of the error is immaterial to the previously issued Condensed Consolidated Financial Statements.
The corrections to the Company's Condensed Consolidated Statement of Income for the three months ended March 31, 2018 were as follows:

CRITICAL ACCOUNTING POLICIES
We maintain our accounting records in accordance with 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 2018 Form 10-K. They include:

• | revenue recognition;

• | regulated utility accounting;

• | income taxes;

• | pension and postretirement health care benefits;

For the three months ended March 31, 2019, 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 FIRST QUARTER 2019 OPERATIONS
COMPARED TO FIRST QUARTER 2018 OPERATIONS
Dollar amounts in thousands unless otherwise stated
Overview
Correction of prior period financial data.
As discussed further in Note 13 the Company corrected an immaterial computational error that understated revenue for the three months ended March 31, 2018.
The net loss for the three months ended March 31, 2019 was $7.6 million or $0.16 net loss per diluted common share compared to a net loss of $0.8 million or $0.02 loss per diluted common share for the first quarter of 2018. The $6.8 million increase in net loss was primarily due to increases in operating expenses which were not fully offset by rate increases and a reduction in accrued unbilled revenue driven by weather. These were partially offset by an increase in unrealized gain on certain benefit plan investments.
The increases in operating expenses in the first quarter compared to the same period last year were: $1.9 million in employee wages, $1.7 million in depreciation and amortization, $1.0 million in maintenance expense, $1.0 million in outside services, $0.6 million in property taxes, and $1.5 million in net interest expenses. These operating expense increases were partially offset by $4.0 million in rate increases and a $0.6 million increase in allowance for equity funds

used during construction. The divergence between operating expense increases and rate relief in the first quarter is partially related to the Company’s tiered rate structure in California, which focuses operating revenue increases into the high-usage summer months while operating expense increases are distributed more evenly throughout the year.
Additionally, certain factors outside the Company’s immediate control significantly increased the net loss, including a $7.1 million reduction in accrued unbilled revenue, which was partially offset by a $3.4 million increase in unrealized gain on certain benefit plan investments. The decrease 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 period-to-period basis.
Operating Revenue
Operating revenue decreased $8.4 million, or 6.3%, to $126.1 million in the first quarter of 2019 as compared to the first quarter of 2018. The factors that impacted the operating revenue for the first quarter of 2019 as compared to the first quarter of 2018 are as follows:

Net change due to rate changes, usage, and other (1) | $ | (2,368 | )
MCBA Revenue (2) | (3,778 | )
Other balancing account revenue (3) | 40 |
Deferral of revenue (4) | (2,336 | )
Net operating revenue increase | $ | (8,442 | )

1. | The net change due to rate changes, usage, and other in the above table was mainly driven by a $7.1 million decrease in accrued unbilled revenue due to a decline in customer usage, which was partially offset by rate increases. The components of the rate increases are as follows:

General rate case | 540 |
Escalation rate increases | 3,006 |
Purchased water and pump tax offsets | 1,103 |
Rate base offsets | 434 |
Total increase in rates | $ | 5,083 |

2. | The MCBA revenue decrease resulted from a decrease in actual water production costs relative to adopted water production costs in the first quarter of 2019 as compared to the first quarter of 2018. The actual water production costs decreased as a result of a decrease in customer consumption in the first quarter of 2019 as compared to the first quarter of 2018. As required by the MCBA mechanism, the decrease in actual water production costs relative to adopted 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 increase in revenue was mainly due to an increase in actual conservation and health care expenses relative to adopted in the first quarter of 2019 as compared to the first quarter of 2018, which was partially offset by a decrease in actual pension expenses relative to adopted in the first quarter of 2019 as compared to the first quarter of 2018.

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 quarter of 2019 as compared to the first quarter of 2018 due to a decline in actual customer usage relative to adopted customer usage in the first quarter of 2019 as compared to the first quarter of 2018.

Total Operating Expenses
Total operating expenses increased $0.9 million, or 0.7%, to $125.6 million in the first quarter of 2019, as compared to $124.7 million in the first quarter of 2018.

Table of Contents
Water production costs consists of purchased water, purchased power, and pump taxes. It represents the largest component of total operating expenses, accounting for approximately 36.3% of total operating expenses in the first quarter of 2019, as compared to 38.2% of total operating expenses in the first quarter of 2018. Water production costs decreased 4.2% in the first quarter of 2019 as compared to the same period last year mainly due to a decrease in customer usage.
Sources of water as a percent of total water production are listed in the following table:

| Three Months Ended March 31
| 2019 |  | 2018
Well production | 45 | % |  | 47 | %
Purchased | 50 | % |  | 49 | %
Surface | 5 | % |  | 4 | %
Total | 100 | % |  | 100 | %

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

| Three Months Ended March 31
| 2019 |  | 2018 |  | Change
Purchased water | $ | 38,216 |  |  | $ | 38,523 |  |  | $ | (307 | )
Purchased power | 5,230 |  |  | 5,523 |  |  | (293 | )
Pump taxes | 2,146 |  |  | 3,560 |  |  | (1,414 | )
Total | $ | 45,592 |  |  | $ | 47,606 |  |  | $ | (2,014 | )

Administrative and general and other operations expenses increased $3.0 million to $46.9 million in the first quarter of 2019, as compared to $43.9 million in the first quarter of 2018. The increase was due primarily to increases of $1.9 million in employee wages, $1.3 million in conservation program costs, $1.0 million of outside services, and $0.9 million of health care costs which were partially offset by a reduction of $1.9 million for deferral of costs associated with deferred revenue and $0.8 million decrease in employee pension benefit and retiree medical costs. Changes in employee pension benefits and water conservation program costs for regulated California operations generally do not affect earnings, as the Company is allowed by the CPUC to record these costs in balancing accounts for future recovery, creating a corresponding change to revenue. Employee and retiree medical expenses are recovered in rates through a balancing account authorized in the 2015 GRC, such that revenues are recovered up to 85% of the variance between adopted and recorded expenses. At March 31, 2019, there were 1,179 employees and at March 31, 2018, there were 1,172 employees.
Maintenance expense increased $1.0 million, or 18.7%, to $6.4 million in the first quarter of 2019, as compared to $5.4 million in the first quarter of 2018, mostly due to increases in transmission and distribution mains and services repairs.
Depreciation and amortization expense increased $1.7 million, or 8.0%, to $22.4 million in the first quarter of 2019, as compared to $20.7 million in the first quarter of 2018, mostly due to capital additions.
Income tax benefit increased $3.3 million, to a $3.0 million income tax benefit in the first quarter of 2019, as compared to a $0.3 million income tax expense in the first quarter of 2018. The income tax benefit increased mostly due to an increase in pre-tax loss from operations. The Company’s estimated combined effective income tax rate for 2019 is 22%.
Property and other taxes increased $0.6 million, or 8.8%, to $7.3 million in the first quarter of 2019, as compared to $6.7 million in the first quarter of 2018, mostly due to an increase in assessed property values.
Other Income and Expenses
Net other income increased $4.0 million in the first quarter of 2019, mostly due to a $3.4 million increase in unrealized gain on certain benefit plan investments, a $0.6 million increase in allowance for equity funds used during construction, and a $1.3 million decrease in other components of net periodic benefit costs.
Interest Expense
Net interest expense increased $1.5 million, or 17.7%, to $10.2 million in the first quarter of 2019, as compared to $8.7 million in the first quarter of 2018. The increase was due primarily to an increase in financing for capital investments and operations as well as increased short-term interest rates.

REGULATORY MATTERS
2019 California Regulatory Activity
California GRC filing
On July 2, 2018, Cal Water filed a GRC requesting new water infrastructure investments of $828.5 million in accordance with the rate case plan for all of its regulated operating districts for the years 2019, 2020, and 2021. The CPUC will evaluate the new water infrastructure improvement investments along with operating budgets to establish water rates that reflect the actual cost of service. The required filing begins an approximately 18-month review process, with any changes in customer rates expected to become effective in 2020. Cal Water has proposed to the CPUC to increase revenues by $50.7 million, or 7.6%, in 2020; $31.5 million, or 4.4%, in 2021; and $33.0 million, or 4.4%, in 2022 as compared to the last authorized revenue. More than half of Cal Water’s proposed $828.5 million of new infrastructure improvements relate to its transmission and distribution pipeline replacement program, and all are necessary to enhance reliability, augment water supply, and upgrade aging water system infrastructure. The plans also reflect Cal Water's cost-control measures to reduce operating and administrative costs. Cal Water is in the process of reviewing parties’ recommendations, evaluating the validity of underlying data, and composing rebuttal testimony. Settlement negotiations with the California Public Advocates Office and intervenors will begin in May, and evidentiary hearings are scheduled for early June. Any rate change as a result of this filing is expected to be effective on January 1, 2020.
Cost of Capital Decision
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 and three other water utilities for the years 2018, 2019, and 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 9.43%, cost of debt of 6.24%, and authorized return on rate base of 7.94%. The adopted capital structure did not change. The adopted returns on debt and equity reduced Cal Water’s 2018 adopted revenue by approximately $6.9 million. The CPUC also authorized continuation of the water cost of capital adjustment mechanism, which provides for an adjustment in the return on equity if the cost of long-term debt as defined by an index of utility debt rates varies from the most recent index by 100 basis points or more in 2019 and 2020.
On March 30, 2018, Cal Water submitted an advice letter that established the 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.
In May of 2018, Cal Water submitted an advice letter to adopt the new cost of capital and capital structure for 2018 in customer rates. The annual adopted gross revenue reduction associated with the May 2018 filing was $6.9 million. The new rates became effective on July 1, 2018.
In 2018, Cal Water recorded a $3.0 million regulatory liability due to the CoC MA. The regulatory liability was for the revenue reduction that Cal Water recorded for the first six months of 2018 during which the new cost of capital and capital structure were yet to be adopted in customer rates. In April of 2019, Cal Water submitted an advice letter to refund the full balance of the cost of capital memorandum account of $3.0 million. The new rates became effective April 15, 2019.
2018 Tax Accounting Memorandum Account (TAMA)
On December 22, 2017, the CPUC sent a letter to All Class A and B Water and Sewer Utilities on the subject of “Changes in Federal Tax Rates for 2018.” The CPUC required Cal Water to 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 rates from January 1, 2018 until current rates are modified to reflect all impacts of the TCJA. 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. In 2018, the Company recorded a $5.4 million regulatory liability due to the changes required by the TCJA. The regulatory liability was for the revenue reduction that the Company recorded for the first six months of 2018 during which the new federal corporate income tax rate was yet to be adopted in customer rates.
In May of 2018, Cal Water submitted an advice letter to adopt the new federal corporate income tax rate in customer rates. The annual adopted gross revenue reduction associated with the May 2018 filing was $11.1 million. The new rates became effective on July 1, 2018.
In April of 2019, Cal Water submitted an advice letter to refund $5.0 million of the tax accounting memorandum account's balance associated with the decrease in the federal corporate income tax rate for Cal Water for the first six months of 2018.
30

Table of Contents
The new rates became effective April 15, 2019. The memorandum account remains open to allow the Commissions to review other changes to Cal Water’s revenue requirements such as ad valorem taxes and excess deferred income taxes.
Escalation increase requests
As a part of the decision on the 2015 GRC, Cal Water was authorized to request annual escalation rate increases for 2019 for those districts that passed the earnings test. In November of 2018, Cal Water requested escalation rate increases in all of its regulated districts. The annual adopted gross revenue associated with the November 2018 filing was $16.2 million. The new rates became effective on January 1, 2019.
WRAM and MCBA filings
In April of 2019, Cal Water submitted an advice letter to true up the revenue under-collections in the 2018 annual WRAMs/MCBAs of its regulated districts. A net under-collection of $29.2 million is being recovered from customers in the form of 12, 18, and greater-than-18-month surcharges and 12 month surcredits. The new rates became effective April 15, 2019. These surcharges/surcredits are 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 November of 2018, Cal Water submitted advice letters to request offsets for increases in purchased water costs and pump taxes in five of its regulated districts totaling $2.0 million. The new rates became effective on January 1, 2019.
Rate base Offset filings
For construction projects that are authorized in GRCs as advice letter projects, companies are allowed to file rate base offsets to increase revenues after the plant is placed into service. In November of 2018, Cal Water submitted advice letters to recover $0.2 million of annual revenue increase for rate base offsets in four of its regulated districts. The new rates became effective on April 15, 2019.
California Drought Memorandum Account
In March of 2018, Cal Water submitted an advice letter to request recovery of 2016 and 2017 incremental drought expenses of $3.3 million. On January 10, 2019, the Commission approved Cal Water's request for recovery of the $3.3 million of incremental expenses; subsequently, Cal Water submitted an advice letter on January 15, 2019 to implement a surcharge to recover the incremental expenses from customers. The new rates became effective on April 15, 2019.
Travis Air Force Base
On September 29, 2016, Cal Water entered into a 50-year agreement with the U.S. Department of Defense to acquire the water distribution assets of and distribute water to most of Travis Air Force Base (TAFB) beginning in 2018. On May 31, 2017, Cal Water submitted an application to the CPUC seeking approval to distribute water service to most of the base and to establish rates for its service.
On December 13, 2018, the CPUC conditionally approved Cal Water’s request to own and operate the TAFB water system as a regulated water utility district. Approval was conditioned upon modifying the contract between Cal Water and the Department of Defense to more clearly assert the CPUC’s jurisdiction over a new Travis District. In January of 2019, Cal Water fulfilled the condition by submitting a contract amendment that was approved by the CPUC. The decision enables Cal Water to acquire the water distribution assets of TAFB from the U.S. Department of Defense and provide water utility service to the base for a term of 50 years. Subject to the terms of the contract with the Department of Defense and the CPUC decision, Cal Water will begin serving TAFB’s more than 15,000 active and reserve personnel and civilians in 2019. The CPUC will regulate water rates, rules, and tariffs for the system as part of Cal Water’s normal three-year rate case cycle.
2019 Regulatory Activity—Other States
2019 Kona (Hawaii Water) GRC Filing
In February of 2019, Hawaii Water filed a GRC application requesting an additional $0.6 million in annual revenues for its Kona Water and Wastewater systems with the Hawaii Public Utilities Commission. The GRC seeks recovery of capital investments in the Kona water and wastewater systems as well as increases in operational expenses since the previous rate case. If approved, the Company anticipates rates would become effective the first quarter of 2020.

2017 Waikoloa (Hawaii Water) GRC Filings
In December of 2017, Hawaii Water filed GRC applications requesting an additional $3.8 million in annual revenues for its Waikoloa Village and Resort Systems with the Hawaii Public Utilities Commission. The GRCs seek recovery of capital investments in the Waikoloa Village and Waikoloa Resort Systems as well as increases in operating expenses since the previous rate case. On January 1, 2019, the HPUC authorized Waikoloa Village rate increases of $0.8 million for 2019 and $0.1 million for 2020. On January 7, 2019, the HPUC authorized Waikoloa Resort rate increases of $0.8 million for 2019, $0.8 million for 2020, and $0.1 million for 2021.
LIQUIDITY
Cash flow from Operations
Cash flow from operations for the first three months of 2019 was $20.1 million compared to $28.3 million for the same period in 2018. 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 2019, we did not make a contribution to our employee pension plan and we made contributions of $7.3 million during the first three months of 2018. During the first three months of 2019, we made contributions of $1.4 million to the other postretirement benefit plans and did not make a contribution during the first three months of 2018. The total 2019 estimated cash contribution to the pension plans is $18.8 million and to the other postretirement benefit plans is $7.9 million.
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.
Investing Activities
During the first three months of 2019 and 2018, we used $59.9 million and $70.7 million, respectively, of cash for company-funded and developer-funded utility plant expenditures. Annual expenditures fluctuate each year due to the availability of construction resources and our ability to obtain construction permits in a timely manner. For 2019, the Company's capital program will be dependent in part on the timing and nature of regulatory approvals in connection with Cal Water's 2018 GRC filing. The Company proposed to the CPUC spending $828.5 million on new projects in 2019-2021. Capital expenditures in California are evaluated in the context of the pending GRC and may change as the case moves forward.
Financing Activities
Net cash provided by financing activities was $52.9 million during the first three months of 2019 compared to net cash used of $17.6 million for the same period in 2018.
During the first three months of 2019 and 2018, we borrowed $60.0 million and $45.0 million, respectively, on our unsecured revolving credit facilities. We did not make a repayment on our unsecured revolving credit facilities borrowings during the first three months of 2019 and we made a repayment of $45.0 million for the same period in 2018.
On March 29, 2019, the Company and Cal Water entered into certain syndicated credit agreements, which provide for unsecured revolving credit facilities of up to an initial aggregate amount of $550 million for a term of five years. The revolving credit facilities amend, expand, and replace the Company’s and its subsidiaries’ prior credit facilities originally entered into on May 10, 2015. The new credit facilities extended the terms until March 29, 2024, and increased Cal Water’s unsecured revolving line of credit. The Company and subsidiaries that it designates may borrow up to $150 million under the Company’s revolving credit facility. Cal Water may borrow up to $400 million under its revolving credit facility; however, all borrowings must be repaid within 24 months unless a different period is required or authorized by the CPUC. Additionally, the credit facilities available to the Company may be increased by up to an incremental $150 million under the Cal Water facility and $50 million under the Company facility, subject in each case to certain conditions. The proceeds from the revolving credit facilities may be used for working capital purposes, including the short-term financing of capital projects. Borrowings under the credit facilities typically have maturities varying between one and six months and will bear interest annually at a rate equal to (i) the base rate or (ii) the Eurodollar rate, plus an applicable margin of 0.650% to 0.875%, depending on the Company and its subsidiaries’ consolidated total capitalization ratio.

Table of Contents
The undercollected net WRAM and MCBA receivable balances were $60.8 million and $68.2 million as of March 31, 2019 and 2018, 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 customers, 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 three months of 2019, we utilized cash generated from operations and borrowings on the unsecured revolving credit facilities to fund operations and capital investments. We did not sell Company common stock during the first three months of 2019 and 2018. We issued $0.5 million of Company common stock for the Company's employee stock purchase plan that went into effect on January 1, 2019. In future periods, management anticipates funding our utility plant needs through a relatively balanced approach between 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. 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 $400.0 million under its revolving credit facility; however, all borrowings must be repaid within 24 months unless a different period is required or 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.
As of March 31, 2019 and December 31, 2018, there were short-term borrowings of $125.1 million and $65.1 million, respectively, outstanding on the unsecured revolving credit 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, 2019, 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 $0.2 million during the first three months of 2019 and $10.2 million during the first three months of 2018. In addition, Cal Water has $100.0 million of First Mortgage Bonds maturing during the second quarter of 2019, which is expected to be repaid using Cal Water's line of credit until long-term financing can be arranged.
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 generally refundable over 40 years. 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 2019, our quarterly common stock dividend payments were $0.1975 per share compared to $0.1875 per share during the first three months of 2018. For the full year 2018, the payout ratio was 55.2% 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 24, 2019 meeting, the Company's Board of Directors declared the second quarter dividend of $0.1975 per share payable on May 17, 2019, to stockholders of record on May 6, 2019. This was our 297th consecutive quarterly dividend.

2019 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 $400.0 million, respectively, for short-term borrowings. As of March 31, 2019, the Company’s and Cal Water’s availability on these unsecured revolving lines of credit was $94.9 million and $330.0 million, respectively.
Book Value and Stockholders of Record
Book value per common share was $14.84 at March 31, 2019 compared to $15.19 at December 31, 2018. There were approximately 1,901 stockholders of record for our common stock as of February 11, 2019.
Utility Plant Expenditures
During the first three months of 2019, utility plant expenditures totaled $59.9 million for company-funded and developer-funded projects. For 2019, the Company's capital program will be dependent in part on the timing and nature of regulatory approvals in connection with Cal Water's 2018 GRC filing. The Company proposed to the CPUC spending $828.5 million on new projects in 2019-2021. Capital expenditures in California are evaluated in the context of the pending GRC and may change as the case moves forward. We do not control third-party-funded utility plant expenditures and therefore are unable to estimate the amount of such projects for 2019.
As of March 31, 2019, construction work in progress was $237.4 million. 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 knowledge, we are meeting water quality, environmental, and other regulatory standards for all Company-owned systems.
Historically, approximately half 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 14.0% 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. Our annual groundwater extraction from managed groundwater basins approximates 29.1 billion gallons or 59.4% of our total annual water supply pumped from wells. Our annual groundwater extraction from unmanaged groundwater basins approximates 13.1 billion gallons or 26.6% 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. Well pump taxes were $2.1 million and $3.6 million for the three months ended March 31, 2019 and 2018, respectively. In 2014, the State of California enacted the Sustainable Groundwater Management Act of 2014. The law and its implementing regulations 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 in California replenish underground water aquifers and fill reservoirs, providing the water supply for subsequent delivery to customers. As of February 5, 2019, the State of California snowpack water content during the 2018-2019 water year is 111% of 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 128% and 133%, respectively, of long-term averages. Management believes that supply pumped from underground aquifers and

purchased from wholesale suppliers will be adequate to meet customer demand during 2019 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.
On May 31, 2018, California's Governor Brown signed two bills (Assembly Bill 1668 and Senate Bill 606) into law that will establish long-term standards for water use efficiency. The bills revise and expand the existing urban water management plan requirements to include five year drought risk assessments, water shortage contingency plans, and annual water supply/demand assessments. By June 30, 2022, the California State Water Resources Control Board, in conjunction with the California Department of Water Resources, will establish long-term water use standards for indoor residential use, outdoor residential use, water losses and other uses. Cal Water will also be required to calculate and report on urban water use target by November 1, 2023 and each November 1 thereafter that compares actual urban water use to the target. Management believes that Cal Water is well-positioned to comply with all regulations required of utilities.
CONTRACTUAL OBLIGATIONS
During the three months ended March 31, 2019, 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 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 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.”
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(e) under the Securities Exchange Act of 1934, as amended) that are designed to ensure that information required to be disclosed in our reports filed or submitted under the Securities Exchange Act of 1934, as amended, 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 Chief Executive Officer and Chief Financial Officer, as appropriate, to allow for timely decisions regarding required disclosure.
In designing and evaluating the disclosure controls and procedures, management, including the Chief Executive Officer and Chief Financial Officer, 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 Chief Executive Officer and our Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of March 31, 2019. Based on that evaluation and the changes made to our internal control over financial reporting in the first quarter of 2019 noted below, we concluded that our disclosure controls and procedures were effective at the reasonable assurance level.

(b) Changes to Internal Control over Financial Reporting
To remediate the material weakness in internal control over financial reporting as of December 31, 2018 disclosed in our Form 10-K Item 9A, management made the following changes during the first quarter of 2019:
•Management revised the design of monthly regulatory balancing account control for the health cost balancing account (HCBA) and pension cost balancing account (PCBA). Monthly detailed calculations are prepared for these balancing accounts, which are reviewed by accounting and rates management who approve the calculations. The monthly review and approval process validates all assumptions and inputs used to determine the monthly balancing account revenue and related balance sheet account adjustments for HCBA and PCBA. This control was implemented in the first quarter of 2019 and internal audit tested the design and operating effectiveness of the resulting control and concluded that it is operating effectively as of March 31, 2019.
•Management designed a new control over GRC settlements or decisions. When GRC approval is final or a rate case settlement is final, management will review the authorized GRC provisions, events, and requirements that have financial reporting impacts. Accounting management will prepare a memo outlining the specific accounting procedures for each GRC balancing account, including examples of the required monthly calculations. The final memo and supporting documents will be provided to rates management to validate all known GRC changes that impact financial reporting have been documented in the memo.
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 customers or other third parties. For more information refer to note 10.
