CALIFORNIA WATER SERVICE GROUP
Notes to Unaudited Condensed Consolidated Financial Statements
March 31, 2022
Dollar amounts in thousands unless otherwise stated
Note 1. Organization and Operations and Basis of Presentation
California Water Service Group (Company) is a holding company that provides water utility and other related services in California, Washington, New Mexico, Hawaii, and Texas through its wholly-owned and non-wholly owned subsidiaries. California Water Service Company (Cal Water), Washington Water Service Company (Washington Water), New Mexico Water Service Company (New Mexico Water), and Hawaii Water Service Company, Inc. (Hawaii Water), provide regulated utility services under the rules and regulations of their respective state’s regulatory commissions (jointly referred to as the Commissions). CWS Utility Services and HWS Utility Services LLC provide non-regulated water utility and utility-related services. TWSC, Inc. (Texas Water) holds regulated and contracted wastewater utilities.
The Company operates in one reportable segment, providing water and related utility services.
Basis of Presentation
The unaudited condensed consolidated interim financial statements have 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. Interim financial information includes the Company's accounts and those of its wholly and non-wholly owned subsidiaries. The non-wholly owned subsidiary was consolidated using the voting interest model as the Company owns a majority of the voting interests in the non-wholly owned subsidiary and includes the Company's accounts and those of its wholly and non-wholly owned subsidiaries. The interim unaudited condensed consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements included in its Annual Report on Form 10-K for the year ended December 31, 2021 as filed with the SEC on February 24, 2022.
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 credit losses, 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.
Noncontrolling Interests
Noncontrolling interests in the Company’s condensed consolidated financial statements represents a 20.45% interest not owned by Texas Water in a consolidated subsidiary. Texas Water obtained control over the subsidiary on May 1, 2021. Since the Company controls this subsidiary, its financial statements are consolidated with those of the Company, and the noncontrolling owner’s 20.45% share of the subsidiary’s net assets and results of operations is deducted and reported as noncontrolling interests on the condensed consolidated balance sheet and as net income or loss attributable to noncontrolling interests in the condensed consolidated statement of operations. The Company reports noncontrolling interests in consolidated entities as a component of equity separate from the Company’s equity. The Company’s net income attributable to California Water Service Group excludes a net loss attributable to the noncontrolling interests.

Note 2. Summary of Significant Accounting Policies
Operating revenue
The following table disaggregates the Company’s operating revenue by source for the three months ended March 31, 2022 and 2021:

| Three Months Ended March 31
| 2022 |  | 2021
Revenue from contracts with customers | $ | 158,933 |  |  | $ | 146,528 |
Regulatory balancing account revenue | 14,060 |  |  | 1,209 |
Total operating revenue | $ | 172,993 |  |  | $ | 147,737 |

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 unaudited condensed 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, 2022 and 2021:

| Three Months Ended March 31
| 2022 |  | 2021
Residential | $ | 106,560 |  |  | $ | 101,371 |
Business | 32,163 |  |  | 27,721 |

Public authorities | 6,985 |  |  | 6,403 |
Other (a) | 7,452 |  |  | 4,990 |
Total revenue from contracts with customers | $ | 158,933 |  |  | $ | 146,528 |

(a) Other includes 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. These mechanisms include the following:
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), Conservation Expense Balancing Account (CEBA), Pension Cost Balancing Account (PCBA), and Health Cost Balancing Account (HCBA), generally 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.
The CPUC issued a decision effective August 27, 2020 requiring that Class A companies submitting GRC filings after the effective date to be (i) precluded from proposing the use of a full decoupling WRAM in their next GRCs and (ii) allowed the use of Monterey-Style Water Revenue Adjustment Mechanisms (MWRAM). Incremental Cost Balancing Accounts (ICBA), which are authorized by statute, would replace the MCBA. The MWRAM tracks the difference between the revenue received for actual metered sales through the tiered volumetric rate and the revenue that would have been received with the same actual metered sales if a uniform rate would have been in effect. The ICBA tracks differences between the authorized per-unit prices of water production costs and actual per-unit prices of water production costs. Cal Water has complied with this decision in its recent 2021 GRC filing.
Non-regulated Revenue
The following table disaggregates the Company’s non-regulated revenue by source for the three months ended March 31, 2022 and 2021:

| Three Months Ended March 31
| 2022 |  | 2021
Operating and maintenance revenue | $ | 3,405 |  |  | $ | 4,087 |
Other non-regulated revenue | 1,150 |  |  | 860 |
Non-regulated revenue from contracts with customers | 4,555 |  |  | 4,947 |
Lease revenue | 642 |  |  | 625 |
Total non-regulated revenue | $ | 5,197 |  |  | $ | 5,572 |

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.

Allowance for credit losses
The Company measures expected credit losses for Customer Receivables, Other Receivables, and Unbilled Revenue on an aggregated level. These receivables are generally trade receivables due in one year or less or expected to be billed and collected in one year or less. The expected credit losses for Other Receivables and Unbilled Revenue are inconsequential. Customer receivables include receivables for water and wastewater services provided to residential customers, business, industrial, public authorities, and other customers. The expected credit losses for business, industrial, public authorities, and other customers are inconsequential. The overall risks related to the Company’s receivables are low as water and wastewater services are seen as essential services. The estimate for the allowance for credit losses is based on a historical loss ratio, in conjunction with a qualitative assessment of elements that impact the collectability of receivables to determine if the allowance for credit losses should be further adjusted in accordance with the accounting guidance for credit losses. Management contemplates available current information such as changes in economic factors, regulatory matters, industry trends, payment options and programs available to customers, and the methods that the Company is able to utilize to ensure payment.
The Company reviewed its allowance for credit losses utilizing a quantitative assessment, which included trend analysis of customer billing and collection, aging by customer class, and unemployment rates since the outbreak of COVID-19 in the first quarter of 2020. The Company also utilized a qualitative assessment, which considered the future collectability on customer outstanding balances, management's estimate of the cash recovery, and a general assessment of the economic conditions of the locations the Company serves due to the outbreak of COVID-19. The Company has resumed shutoffs for non-payment in New Mexico Water and Hawaii Water and plans to resume shutoffs for non-payment in Cal Water and Washington Water during the second quarter of 2022. The Company has also contemplated funds that the Company received and applied to customer accounts from the California Water and Wastewater Arrearage Payment Program (Program). The Program was created by the California Legislature, is administered by the State Water Resources Control Board and provided relief to community water and wastewater systems for unpaid bills – arrearages – related to the COVID-19 pandemic. Based on the above assessments, the Company adjusted its allowance for credit losses accordingly.
The following table presents the activity in the allowance for credit losses for the 3-month period ended March 31, 2022 and 12-month period ended December 31, 2021:

Allowance for credit losses | March 31, 2022 |  | December 31, 2021
Beginning balance | $ | 3,743 |  |  | $ | 5,246 |
Provision for credit loss expense | 1,548 |  |  | 1,088 |
Write-offs | (234) |  |  | (3,113) |
Recoveries | 103 |  |  | 522 |
Total ending allowance balance | $ | 5,160 |  |  | $ | 3,743 |

Cash, Cash Equivalents, and Restricted Cash
The following table provides a reconciliation of cash, cash equivalents, and restricted cash within the Condensed Consolidated Balance Sheets that sum to the total of the same such amounts shown on the Condensed Consolidated Statements of Cash Flows:

| March 31, 2022 |  | December 31, 2021
Cash and cash equivalents | $ | 68,379 |  |  | $ | 78,380 |
Restricted cash (included in "taxes, prepaid expenses and other assets") | 3,473 |  |  | 2,273 |
Total cash, cash equivalents, and restricted cash shown in the statements of cash flows | $ | 71,852 |  |  | $ | 80,653 |

Adoption of New Accounting Standards
In October of 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. In a business combination, an acquirer generally recognizes assets acquired and liabilities assumed, including contract assets and contract liabilities, at their respective fair value on the acquisition date. ASU 2021-08 requires that in a business combination, an acquirer should recognize and measure contract assets acquired and contract liabilities assumed in a business combination in accordance with Topic 606, Revenue from Contracts with Customers. The guidance provides certain practical expedients for acquirers when recognizing and measuring acquired contract assets and contract liabilities from revenue contracts with customers in a business combination. The guidance is effective for annual reporting periods beginning after December 15, 2022, including interim

Table of Contents
periods within those fiscal years. ASU 2021-08 should be applied prospectively for acquisitions occurring on or after the effective date of the amendments, and early adoption is permitted. The Company is evaluating the requirements of the guidance to determine the impact on the Company's financial statements and footnote disclosures upon adoption.
Note 3. Stock-based Compensation
The Company's equity incentive plan was approved and amended by stockholders on April 27, 2005 and May 20, 2014. The Company is authorized to issue awards up to 2,000,000 shares of common stock.
During the first three months of 2022, the Company granted Restricted Stock Awards (RSAs) to Officers and to members of the Board of Directors. An RSA share represents a restricted share of the Company's common stock and is valued based on the fair market value of the Company's common stock at the date of grant. RSAs granted to Officers vest over 36 months with the first year cliff vesting. In general, RSAs granted to Board members vest at the end of 12 months. The RSAs are recognized as expense evenly over 36 months for the shares granted to Officers and 12 months for the shares granted to Board members. As of March 31, 2022, there was approximately $3.4 million of total unrecognized compensation cost related to RSAs. The cost is expected to be recognized over a weighted average period of 1.9 years.
A summary of the status of the outstanding RSAs as of March 31, 2022 is presented below:

| Number of RSA Shares |  | Weighted-Average Grant-Date Fair Value
RSAs at January 1, 2022 | 62,691 |  |  | $ | 53.49 |
Granted | 42,057 |  |  | 56.42 |
Vested | (39,323) |  |  | 53.73 |
RSAs at March 31, 2022 | 65,425 |  |  | $ | 55.23 |

During the first three months of 2022, the Company granted performance-based Restricted Stock Units (RSUs) to Officers. An RSU represents the right to receive a share of the Company's common stock. Each award reflects a target number shares of common stock that may be issued to the award recipient. The 2022 awards may be earned upon the completion of a 3-year performance period. Whether RSUs are earned at the end of the performance period will be determined based on the achievement of certain performance objectives set by the Organization and Compensation Committee of the Board of Directors in connection with the issuance of the RSUs. The performance objectives are based on the Company's business plan covering the performance period. The performance objectives include achieving the budgeted return on equity, budgeted investment in utility plant, customer service standards, employee safety standards and water quality standards. Depending on the results achieved during the 3-year performance period, the actual number of shares that a grant recipient receives at the end of the performance period may range from 0% to 200% of the target shares granted, provided that the grantee is continuously employed by the Company through the vesting date. If prior to the vesting date employment is terminated by reason of death, disability or normal retirement, then a pro rata portion of this award will vest. The RSUs are recognized as expense ratably over the 3-year performance period using a fair market value of the Company's common share at the date of grant and an estimated number of RSUs earned during the performance period. As of March 31, 2022, there was approximately $3.6 million of total unrecognized compensation cost related to RSUs. The cost is expected to be recognized over a weighted average period of 2.0 years.
A summary of the status of the outstanding RSUs as of March 31, 2022 is presented below:

| Number of RSU Shares |  | Weighted-Average Grant-Date Fair Value
RSUs at January 1, 2022 | 90,942 |  |  | $ | 52.71 |
Granted | 35,911 |  |  | 56.42 |
Performance criteria adjustment | 12,173 |  |  | 58.63 |
Vested | (32,913) |  |  | 58.63 |
Forfeited | (5,733) |  |  | 52.83 |
RSUs at March 31, 2022 | 100,380 |  |  | $ | 54.01 |

The Company has recorded compensation costs for the RSAs and RSUs that are included in administrative and general operating expenses in the amount of $0.5 million and $1.3 million for the three months ended March 31, 2022 and 2021, respectively.

Note 5. Earnings (Loss) Per Share of Common Stock
The computations of basic and diluted earnings (loss) per share of common stock are noted in the table below. Basic earnings (loss) per share of common stock is computed by dividing the net income (loss) attributable to California Water Service Group 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.

Note 6. Pension Plan and Other Postretirement Benefits
The Company provides a qualified, defined-benefit, non-contributory pension plan for substantially all employees. The Company makes annual contributions to fund the amounts accrued for in the qualified pension plan. The Company also maintains an unfunded, non-qualified, supplemental executive retirement plan. The costs of the plans are charged to expense or are capitalized in utility plant as appropriate.
The Company offers medical, dental, vision, and life insurance benefits for retirees and their spouses and dependents. Participants are required to pay a premium, which offsets a portion of the cost.
Cash contributions made by the Company to the pension plans were $5.1 million and $9.4 million for the three months ended March 31, 2022 and 2021, respectively. Cash contributions made by the Company to the other postretirement benefit plans were $0.1 million and $1.2 million for the three months ended March 31, 2022 and 2021, respectively.

Note 7. Short-term and Long-term Borrowings
On May 11, 2021, Cal Water completed the sale and issuance of $280.0 million in aggregate principal amount of First Mortgage Bonds (the Bonds) in a private placement. The Bonds consist of $130.0 million of 2.87% bonds, series ZZZ, maturing May 11, 2051, and $150.0 million of 3.02% bonds, series 1, maturing May 11, 2061. Interest on the bonds will accrue semi-annually and be payable in arrears on May 11 and November 11 of each year, commencing on November 11, 2021. The Bonds will rank equally with all of Cal Water’s other First Mortgage Bonds and will be secured by liens on Cal Water’s properties, subject to certain exceptions and permitted liens. Cal Water used the net proceeds from the sale of the Bonds to refinance existing indebtedness and for general corporate purposes. The Bonds were not registered under the Securities Act of 1933 and may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements.
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 $550.0 million for a term of five years. 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. Additionally, the credit facilities may be increased by up to an incremental $150.0 million under the Cal Water facility and $50.0 million under the Company facility, subject in each case to certain conditions.
The revolving credit facilities 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 $35.0 million as of March 31, 2022 and December 31, 2021. There were $15.0 million and no borrowings on the Cal Water line of credit as of March 31, 2022 and December 31, 2021, respectively. The average borrowing rate for borrowings on the Company and Cal Water lines of credit during the three months ended March 31, 2022 and 2021 was 0.98%.
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
| 2022 |  | 2021
Income tax (benefit) expense | $ | (905) |  |  | $ | 257 |

Income tax benefit increased $1.2 million to $0.9 million income tax benefit in the first quarter of 2022 as compared to $0.3 million income tax expense in the first quarter of 2021. The Company’s effective tax rate was 12% before discrete items as of March 31, 2022 and 6.0% as of March 31, 2021. The increase in effective tax rate was primarily due to an increase in state tax benefits from repairs and other deductions partially offset by a decrease in refunds of excess 2017 deferred federal income taxes.
The Company had unrecognized tax benefits of approximately $16.2 million and $14.1 million as of March 31, 2022 and 2021, respectively. Included in the balance of unrecognized tax benefits as of March 31, 2022 and 2021, is $4.1 million and $3.9 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.

Note 10. Commitments and Contingencies
Commitments
The Company has significant commitments to purchase water from water wholesalers. The Company also has operating and finance leases for water systems, offices, land easements, licenses, equipment, and other facilities. These commitments and leases are described in the Company's Annual Report on Form 10-K for the year ended December 31, 2021.
As of March 31, 2022, there were no significant changes in these commitments from December 31, 2021.
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 and to request recovery of these costs in future filings.
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, 2022 and December 31, 2021, the Company recognized a liability of $5.4 million and $3.5 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 Company 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.
15

Table of Contents
Specific valuation methods include the following:
Cash, Accounts receivable, short-term borrowings, 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 of similar securities, 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 0.60%.

CRITICAL ACCOUNTING ESTIMATES
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 Company's Annual Report on Form 10-K for the year ended December 31, 2021. They include:
•revenue recognition;
•regulated utility accounting;
•income taxes; and
•pension and postretirement health care benefits.
17

Table of Contents
For the three months ended March 31, 2022, 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.
COVID-19
During 2021 and for the three months ended March 31, 2022 and through April 28, 2022, the COVID-19 pandemic has not had a significant impact on our business or operations. We have resumed shutoffs for non-payment in New Mexico Water and Hawaii Water and plan to resume shutoffs for non-payment in Cal Water and Washington Water during the second quarter of 2022.
If we need to close any of our facilities due to outbreaks of COVID-19 or if a critical number of our employees become too ill to work, our business operations could be materially adversely affected in a rapid manner. Company employees have returned to the office full-time. We continue to be vigilant for employee and customer safety, we encourage and incentivize vaccination, and we follow local masking rules as applicable. The impact of the COVID-19 pandemic is fluid and continues to evolve, and therefore, we cannot predict the extent to which our business, results of operations, financial condition or liquidity will ultimately be impacted.
RESULTS OF FIRST QUARTER 2022 OPERATIONS
COMPARED TO FIRST QUARTER 2021 OPERATIONS
Dollar amounts in thousands unless otherwise stated
Overview
Net Income Attributable to California Water Service Group
Net income attributable to California Water Service Group for the first quarter of 2022 was $1.1 million or $0.02 earnings per diluted common share, compared to net loss attributable to California Water Service Group of $3.0 million or $0.06 loss per diluted common share for the first quarter of 2021.
The $4.1 million increase in net income attributable to California Water Service Group was driven primarily by general rate increases of $5.2 million, an operating revenue increase of $2.7 million from prior year acquisitions, a change in deferred revenue added $1.8 million to net operating income, and an income tax benefit increase of $1.3 million. These positive factors were partially offset by increases in employee wage costs of $2.2 million, depreciation and amortization expenses of $1.8 million, and interest expense of $1.0 million.
Additionally, certain factors outside the Company’s immediate control impacted net income attributable to the Company, including a $3.3 million decrease in value of non-qualified benefit plan investments partially offset by a $2.3 million increase in accrued unbilled revenue.
Operating Revenue
Operating revenue increased $25.3 million, or 17.1%, to $173.0 million in the first quarter of 2022 as compared to the first quarter of 2021, with such change attributed to the following:

Net change due to WRAM, rate changes, usage, and other (1) | $ | 11,494 |
MCBA Revenue (2) | 4,235 |
Other balancing account revenue (3) | 103 |
Deferral of revenue (4) | 9,425 |
Net operating revenue increase | $ | 25,257 |

1.The net change due to WRAM, rate changes, usage, and other in the above table was primarily driven by rate increases, the components of which are set forth in the table below, a $2.7 million increase in operating revenue from prior year acquisitions, and a $2.3 million increase in accrued unbilled revenue.

Escalation rate increases | 3,852 |
Purchased water and pump tax offsets | 1,314 |
Rate base offsets | 27 |
Total increase in rates | $ | 5,193 |

Table of Contents
2.MCBA revenue is the variance between adopted water production costs and actual water production costs. For the first quarter of 2022, we recognized an increase of $8.3 million of MCBA revenue as compared to an increase to revenue of $4.1 million for the first quarter 2021. The MCBA revenue increase in the first three months of 2022 as compared to the first three months of 2021 resulted from an increase in actual water production costs relative to adopted water production costs, due to a 7% increase in purchased water production.
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. For the first three months of 2022, we recognized a net decrease to revenue of $2.1 million for these balancing accounts as compared to a net decrease of $2.2 million of revenue for the first three months of 2021. The year-over-year increase in revenue was primarily due to an increase in actual conservation and health care expenses relative to adopted partially offset by a decrease in actual pension expenses relative to adopted.
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 decreased in the first quarter of 2022 as compared to the first quarter of 2021 due to a decrease in the balancing account revenue expected to be collected beyond 24 months.
Total Operating Expenses
Total operating expenses increased $19.1 million, or 13.2%, to $163.9 million in the first quarter of 2022, as compared to $144.8 million in the first quarter of 2021.
Water production cost consists of purchased water, purchased power, and pump taxes. It represents the largest component of total operating expenses, accounting for approximately 37.6% of total operating expenses for the first quarter of 2022, as compared to 37.9% of total operating expenses for the first quarter of 2021. Water production costs increased 12.2% in the first quarter of 2022 as compared to the same period last year primarily due to increases in purchased water quantities and an increase in rates from our purchased water wholesalers.
Sources of water as a percent of total water production are listed in the following table:

| Three Months Ended March 31
| 2022 |  | 2021
Well production | 49 | % |  | 47 | %
Purchased | 50 | % |  | 48 | %
Surface | 1 | % |  | 5 | %
Total | 100 | % |  | 100 | %

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

| Three Months Ended March 31
| 2022 |  | 2021 |  | Change
Purchased water | $ | 48,792 |  |  | $ | 44,765 |  |  | $ | 4,027 |
Purchased power | 8,399 |  |  | 6,504 |  |  | 1,895 |
Pump taxes | 4,347 |  |  | 3,557 |  |  | 790 |
Total | $ | 61,538 |  |  | $ | 54,826 |  |  | $ | 6,712 |

Administrative and general and other operations expenses increased $11.0 million, or 22.7%, to $59.3 million in the first quarter of 2022, as compared to $48.3 million in the first quarter of 2021. The increase was primarily due to an increase in the costs associated with the reduction of deferred revenue of $7.7 million, employee labor costs of $2.1 million, outside legal and consulting service costs of $0.9 million, and employee health care costs of $0.8 million. Changes in conservation program expense, employee pension benefits, and employee and retiree medical costs for regulated California operations generally do not affect net income, as the Company has been allowed by the CPUC to record these costs in balancing accounts for future recovery, creating a corresponding change to revenue.
Maintenance expense increased $0.5 million, or 8.5%, to $7.3 million in the first quarter of 2022, as compared to $6.8 million in the first quarter of 2021, due to repairs of facilities and equipment.
19

Table of Contents
Depreciation and amortization expense increased $1.8 million, or 6.4%, to $28.8 million in the first quarter of 2022, as compared to $27.0 million in the first quarter of 2021, mostly due to utility plant placed in service in 2021.
Income tax benefit increased $1.3 million, resulting in a $1.4 million tax benefit in the first quarter of 2022, as compared to a $0.1 million income tax benefit in the first quarter of 2021. The increase was primarily due to an increase in the tax benefit from the flow-through method of accounting for “repairs” deductions on state corporate income tax filings and resolution of a prior year Hawaii Water GRC deferred tax asset issue. These tax benefits were partially offset by a decrease in customer refunds of excess deferred federal income taxes.
Property and other taxes increased $0.4 million to $8.4 million in the first quarter of 2022, as compared to $8.0 million in the same period of 2021, mostly due to an increase in assessed property values for utility plant in service.
Other Income and Expenses
Net other income decreased $1.3 million to $2.7 million in the first quarter of 2022, as compared to a net other income of $4.0 million in the first quarter of 2021, due primarily to a $3.3 million decrease in the value of non-qualified benefit plan investments, which was partially offset by a $1.0 million increase in other components of net periodic benefit credit, a $0.4 million increase in allowance for equity funds used during construction, and a $0.4 million gain on company owned life insurance.
Interest Expense
Net interest expense increased $1.0 million, or 10.1%, to $10.9 million in the first quarter of 2022, as compared to $9.9 million in the first quarter of 2021. The increase was due primarily to an increase in financing to support the capital investment program.
REGULATORY MATTERS
2021 California Regulatory Activity
2021 GRC Filing
California Public Advocates Office reviewed Cal Water's 2021 GRC filing and submitted its report in February 2022. Cal Water reviewed California Public Advocates Office recommendations, evaluated the validity of the underlying data, and composed and filed rebuttal testimony with the CPUC in April 2022. Settlement negotiations with the California Public Advocates Office and intervenors began in the second quarter of 2022 and evidentiary hearings are also scheduled for the second quarter of 2022. Any rate change resulting from this filing is not expected to be effective until January 1, 2023 at the earliest.
2021 Cost of Capital Application
On May 3, 2021, Cal Water filed its required application with the CPUC to review its cost of capital for 2022 through 2024. Cal Water currently has an approved return on equity of 9.2%, a cost of debt of 5.51%, and a 53.4% equity capital structure. Cal Water requested a return on equity of 10.35%, a cost of debt of 4.23%, and a 53.4% equity capital structure. The California Public Advocates Office recommends a return on equity of 7.81%, a cost of debt of 4.23%, and a 49.4% equity capital structure The CPUC will evaluate the proposal along with proposals of other parties, and in accordance with its standard process, is currently expected to issue a decision in the latter half of 2022.
California Drought Memorandum Account (DRMA)
In June 2021, Cal Water submitted advice letters to request a DRMA to track the incremental operational and administrative costs incurred to further implement updated Rule 14.1 for voluntary conservation measures and Schedule 14.1 for implementation of our Water Shortage Contingency Plan, including activities related to enhanced conservation efforts, staffing, and capital expenditures to ensure a safe, reliable supply of water. The DRMA would also track monies paid by customers for fines, penalties, or other compliance measures associated with water use violations; and penalties paid by Cal Water to its water wholesalers. The DRMA was approved by the CPUC with an effective date of June 14, 2021. Cal Water has incurred $0.8 million of cumulative DRMA related costs, of which $0.2 million was incurred in the first three months of 2022.
The California State Governor has issued a drought declaration for all California counties through five State of Emergency Proclamations with the most recent on October 19, 2021. Given these drought proclamations and current water usage levels in Bakersfield, Bay Area Region, Bear Gulch, Dominguez, East Los Angeles, Hermosa Redondo, Kern River Valley, Livermore, Los Altos, Visalia, Palos Verdes, and Westlake, Cal Water has activated Stage 2 of the “Water Use Restrictions of its Water Shortage Contingency Plan” of Schedule 14.1 for these 12 service areas.

In Stage 1, irrigating ornamental landscape with potable water is prohibited during the hours of 8:00 a.m. and 6:00 p.m. For Stage 2, irrigating ornamental landscapes with potable water is limited to no more than three days per week as well as prohibited during the hours of 8:00 a.m. and 6:00 p.m. In addition this stage states that new connections may not install single-pass cooling systems for air conditioning or other cooling system applications unless required for health or safety reasons.
Escalation Increase Requests
As part of the decision on the 2018 GRC, Cal Water was authorized to request annual escalation rate increases for 2022 for those districts that passed the earnings test. In November of 2021, Cal Water requested escalation rate increases for 2022 in 19 of its regulated districts. The increase in annual adopted gross revenue associated with the November 2021 filing was $21.7 million. The new rates were implemented on January 1, 2022.
Expense Offset Requests
Expense offsets are dollar-for-dollar increases in revenue to match increased expenses, and therefore do not affect net operating income. In December of 2021, Cal Water submitted an advice letter to request offsets for increases in purchased water costs and pump taxes in seven of its regulated districts totaling $5.2 million. The new rates were implemented on January 1, 2022.
Rate Base Offset Requests
For construction projects authorized in GRCs as advice letter projects, Cal Water is allowed to request rate base offsets to increase revenues after the project goes into service. In November of 2021, Cal Water submitted an advice letter to recover $0.2 million of annual revenue increase for a rate base offset in one of its regulated districts. The new rates were implemented on January 1, 2022.
In March of 2022, Cal Water submitted an advice letter to recover $0.1 million of annual revenue increase for a rate base offset in one of its regulated districts. The new rates were implemented on April 15, 2022.
WRAM/MCBA Filings
In April of 2022, Cal Water submitted an advice letter to true up the revenue under-collections for the 2021 annual WRAMs/MCBAs of its regulated districts. A net under-collection of $54.1 million is being recovered/refunded from/to customers in the form of 12, 18, and greater-than-18-month surcharges and 12 month surcredits. The new rates incorporate net WRAM/MCBA balances that were previously approved for recovery and were implemented on April 15, 2022.
Regulatory Activity - Other States
Kona Water Service Company GRC (Hawaii Water)
In May of 2021, Hawaii Water submitted a private letter ruling (PLR) to the IRS requesting a ruling on the treatment of deferred taxes because of the TCJA. A favorable decision on the PLR was received on November 18, 2021. The Consumer Advocates and Hawaii Water submitted a joint stipulation to the Hawaii Public Utility Commission (HPUC) incorporating the PLR into revised water rates on March 2, 2022. Hawaii Water is awaiting approval from the HPUC.
LIQUIDITY
Cash flow from Operations
Cash flow from operations for the first three months of 2022 was $54.2 million compared to $30.0 million for the same period in 2021. The increase in the first three months of 2022 as compared to 2021 was primarily due to receipt of $20.8 million from the Water Arrearages Payment Program. 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 2022, we made contributions of $5.1 million to our employee pension plan compared to contributions of $9.4 million during the first three months of 2021. During the first three months of 2022, we made contributions of $0.1 million to the other postretirement benefit plans compared to contributions of $1.2 million during the first three months of 2021. The full-year 2022 estimated cash contribution to the pension plans and other postretirement benefits plans are expected to be approximately $16.1 million and $0.7 million, respectively.
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 unsecured revolving credit facilities 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 greater-than-normal precipitation falls in our service areas or temperatures are lower than normal, especially in the summer months. Aged accounts receivable past due more than 60 days decreased from $26.2 million as of December 31, 2021 to $15.3 million as of March 31, 2022 mostly due to the application of $16.6 million of Program funds.
Investing Activities
During the first three months of 2022 and 2021, we used $68.5 million and $66.8 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 2022, the Company's capital program will be dependent in part on the timing and nature of regulatory approvals in connection with Cal Water's 2021 GRC filing. The Company proposed to the CPUC spending $1.0 billion on water infrastructure investments in 2022-2024. 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 $5.7 million during the first three months of 2022 compared to $78.8 million of net cash provided by financing activities for the same period in 2021. For 2022, this includes our issuance of $0.6 million of common stock through our employee stock purchase plan. For 2021, this includes our issuance of $22.7 million of Company common stock through our at-the-market equity program and $0.5 million through our employee stock purchase plan.
During the first three months of 2022 and 2021, we borrowed $30.0 million and $105.0 million, respectively, on our unsecured revolving credit facilities. We made a repayment on our unsecured revolving credit facilities of $15.0 million and $40.0 million during the first three months of 2022 and 2021, respectively.
The net WRAM and MCBA receivable balances were $79.6 million and $69.7 million as of March 31, 2022 and 2021, respectively. The receivable balances were primarily financed by Cal Water using short-term and long-term financing arrangements to meet operational cash requirements. Interest on the receivable balances, which represents the interest recoverable from customers, is limited to the then-current 90-day commercial paper rates which typically are significantly lower than Cal Water’s short and long-term financing rates.
Short-Term and Long-Term Financing
During the first three months of 2022, we utilized cash generated from operations and borrowings on the unsecured revolving credit facilities to fund operations and capital investments.
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 unsecured revolving credit facilities may be used for working capital purposes, including the short-term financing of utility plant projects.
As of March 31, 2022 and December 31, 2021, there were short-term borrowings of $50.0 million and $35.0 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, Hawaii Water and Texas 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, 2022, we are in compliance with all of the covenant requirements and are eligible to use the full amount of the undrawn portion of our unsecured revolving credit facilities.

Long-term financing, which includes First Mortgage Bonds, 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 planned utility plant expenditures 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.
Equity Issuance
We expect to renew our at-the-market equity program in the near term, with a planned size of up to $350.0 million over three years. We intend to use proceeds from sales under this program for general corporate purposes.
Summarized Financial Information for Guarantors and the Issuer of Guaranteed Securities.
On April 17, 2009, Cal Water (Issuer) issued $100.0 million aggregate principal amount of 5.500% First Mortgage Bonds due 2040, all of which are fully and unconditionally guaranteed by the Company (Guarantor). Certain subsidiaries of the Company do not guarantee the security and are referred to as Non-guarantors. The Guarantor fully, absolutely, irrevocably and unconditionally guarantees the due and punctual payment when due, whether at stated maturity, by acceleration, by notice of prepayment or otherwise, of the principal of, premium, if any, and interest on the bonds. The bonds rank equally among Cal Water's other First Mortgage Bonds.
The following tables present summarized financial information of the Issuer subsidiary and the Guarantor. The information presented below excludes eliminations necessary to arrive at the information on a consolidated basis. In presenting the summarized financial statements, the equity method of accounting has been applied to the Guarantor interests in the Issuer. The summarized information excludes financial information of the Non-guarantors, including earnings from and investments in these entities.

Dividends
During the first three months of 2022, our quarterly common stock dividend payments were $0.2500 per share compared to $0.2300 per share during the first three months of 2021. For the full year 2021, the payout ratio was 46.9% 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 27, 2022 meeting, the Company's Board of Directors declared the second quarter dividend of $0.2500 per share payable on May 20, 2022, to stockholders of record on May 9, 2022. This was our 309th consecutive quarterly dividend.
2022 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, 2022, the Company’s and Cal Water’s availability on these unsecured revolving lines of credit was $115.0 million and $385.0 million, respectively.
Book Value and Stockholders of Record
Book value per common share was $21.66 at March 31, 2022 compared to $22.02 at December 31, 2021. There were approximately 1,903 stockholders of record for our common stock as of February 7, 2022.
Utility Plant Expenditures
During the first three months of 2022, utility plant expenditures totaled $68.5 million for Company-funded and developer-funded projects. For 2022, the Company's capital program will be dependent in part on the timing and nature of regulatory approvals in connection with Cal Water's 2021 GRC filing. The Company proposed to the CPUC spending $1.0 billion on water infrastructure investments in 2022-2024. Capital expenditures in California are evaluated in the context of the pending GRC and may change as the case moves forward.
As of March 31, 2022, construction work in progress was $251.8 million. Construction 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 5.4 billion gallons or 10.3% 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 32.1 billion gallons or 61.1% of our total annual water supply pumped from wells. Our annual groundwater extraction from unmanaged groundwater basins approximates 15.0 billion gallons or 28.6% 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 financially support these groundwater recharge facilities by paying well pump taxes. Our well pump taxes were $4.3 million and $3.6 million for the three months ended March 31, 2022 and 2021, 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 after the act's provisions are fully implemented, substantially all the Company's California groundwater will be produced from sustainably 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 March 31, 2022, the State of California snowpack water content during the 2021-2022 water year is 30% 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 have recorded 43% and 44%, respectively, of long-term averages. Management believes that, notwithstanding lower-than-average snowpack water content, supply pumped from underground aquifers and purchased from wholesale suppliers will be adequate to meet customer demand during 2022 and thereafter. 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 currently available treatment processes.
On May 31, 2018, California's Governor 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, is expected to 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 such regulations.
CONTRACTUAL OBLIGATIONS
During the three months ended March 31, 2022, 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.
25

Table of Contents
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, 2022. 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, 2022, that has materially affected, or is reasonably likely to materially affect, our internal controls over financial reporting.
PART II OTHER INFORMATION
Item 1.
LEGAL PROCEEDINGS
From time to time, the Company is involved in various disputes and litigation matters that arise in the ordinary course of business. The status of each significant matter is reviewed and assessed for potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and the amount of the range of loss can be reasonably 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.
