Notes to Unaudited Condensed Consolidated Financial Statements
June 30, 2021
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, Hawaii, and Texas 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), Hawaii Water Service Company, Inc. (Hawaii Water), and TWSC, Inc. (Texas 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 included in its Annual Report on Form 10-K for the year ended December 31, 2020 as filed with the SEC on February 25, 2021.
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 the 38.87% 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 38.87% 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 loss attributable to noncontrolling interests in the condensed consolidated statement of operations.

Total operating revenue | $ | 360,860 |  |  | $ | 301,047 |

(a) As further discussed below, no amounts were recorded for the Company’s Water Revenue Adjustment Mechanism (WRAM), Modified Cost Balancing Account (MCBA), Pension Cost Balancing Account (PCBA), and Health Cost Balancing Account (HCBA) for the three and six months ended June 30, 2020 due to the delay in the resolution of the 2018 General Rate Case (GRC).
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 tables, revenue from contracts with customers is disaggregated by class of customers for the three and six months ended June 30, 2021 and 2020:

| Three Months Ended June 30

Total revenue from contracts with customers | $ | 358,985 |  |  | $ | 307,330 |

(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 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 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 MCBA, Conservation Expense Balancing Account (CEBA), PCBA, and 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.
For 2021, the WRAM, MCBA, PCBA, and HCBA have all been authorized by the CPUC with the approval of the 2018 GRC in the fourth quarter of 2020. For 2020, the WRAM, MCBA, PCBA, and HCBA were being litigated in the 2018 GRC. As a result, the Company determined that the regulatory asset and liability recognition criteria under accounting standards for regulated entities was not met and the Company did not record regulatory assets or liabilities with respect to these mechanisms for the first six months of 2020. As the CEBA was not being litigated in the then-pending 2018 GRC, the Company recorded a regulatory liability for the CEBA for the first six months of 2020. The Company determined that the CEBA met the regulatory liability recognition criteria under accounting standards for regulated utilities.
Due to the delay in the resolution of the 2018 GRC, the CPUC authorized Cal Water to track the effect of the delay on customer billings in an interim rates memorandum account (IRMA) effective January 1, 2020. Variances between actual customer billings and those that would have been billed assuming the GRC had been effective January 1, 2020 are recorded as regulatory balancing account revenue. Rates for the 2018 GRC were implemented on February 1, 2021; as a result, Cal Water recorded an IRMA regulatory asset for January of 2021. For the first six months of 2020, the Company did not record a regulatory asset for the IRMA because the regulatory asset recognition criteria under accounting standards for regulated entities was not met as the 2018 GRC was still pending resolution as of the end of the quarter.
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 tables disaggregate the Company’s non-regulated revenue by source for the three and six months ended June 30, 2021 and 2020:

| Three Months Ended June 30
| 2021 |  | 2020
Operating and maintenance revenue | $ | 3,925 |  |  | $ | 2,789 |
Other non-regulated revenue | 796 |  |  | 834 |
Non-regulated revenue from contracts with customers | 4,721 |  |  | 3,623 |
Lease revenue | 653 |  |  | 585 |
Total non-regulated revenue | $ | 5,374 |  |  | $ | 4,208 |

| Six Months Ended June 30
| 2021 |  | 2020
Operating and maintenance revenue | $ | 8,013 |  |  | $ | 5,288 |
Other non-regulated revenue | 1,655 |  |  | 1,599 |
Non-regulated revenue from contracts with customers | 9,668 |  |  | 6,887 |
Lease revenue | 1,278 |  |  | 1,148 |
Total non-regulated revenue | $ | 10,946 |  |  | $ | 8,035 |

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.
10

Table of Contents
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 is complying with the CPUC requirements to suspend customer disconnections for non-payment and ceased agency collection activities, and anticipates this situation will continue until further notice. Based on the above assessments, the Company expects an increase in customer receivable write-offs as compared to historical experiences and adjusted its allowance for credit losses, accordingly.
The following table presents the activity in the allowance for credit losses for the period ended June 30, 2021 and December 31, 2020:

Allowance for credit losses | June 30, 2021 |  | December 31, 2020
Beginning balance | 5,246 |  |  | 771 |
Provision for credit loss expense | 2,126 |  |  | 5,716 |

Total cash, cash equivalents, and restricted cash shown in the statements of cash flows | $ | 67,497 |  |  | $ | 45,129 |

Adoption of New Accounting Standards
In December 2019, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2019-12, Simplifying the Accounting for Income Taxes (Topic 740). ASU 2019-12 simplifies the accounting for income taxes by removing certain exceptions for performing intraperiod tax allocations, recognizing deferred taxes for investments, and calculating income taxes in interim periods. The guidance also simplifies the accounting for franchise taxes, transactions that result in a step-up in the tax basis of goodwill, and the effect of enacted changes in tax laws or rates in interim periods. The Company adopted ASU 2019-12 in the first quarter of 2021 and the adoption did not have a material impact to the Company’s Condensed Consolidated Financial Statements.

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 six months of 2021, 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 June 30, 2021, there was approximately $3.0 million of total unrecognized compensation cost related to RSAs. The cost is expected to be recognized over a weighted average period of 1.6 years.
A summary of the status of the outstanding RSAs as of June 30, 2021 is presented below:

| Number of RSA Shares |  | Weighted-Average Grant-Date Fair Value
RSAs at January 1, 2021 | 51,561 |  |  | $ | 50.92 |
Granted | 50,981 |  |  | 53.92 |
Vested | (32,210) |  |  | 50.39 |
Forfeited | — |  |  | — |
RSAs at June 30, 2021 | 70,332 |  |  | $ | 53.34 |

During the first six months of 2021, 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 2021 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. RSUs are not included in diluted shares until earned. 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 June 30, 2021, there was approximately $2.8 million of total unrecognized compensation cost related to RSUs. The cost is expected to be recognized over a weighted average period of 1.7 years.
A summary of the status of the outstanding RSUs as of June 30, 2021 is presented below:

| Number of RSU Shares |  | Weighted-Average Grant-Date Fair Value
RSUs at January 1, 2021 | 87,787 |  |  | $ | 46.62 |
Granted | 31,749 |  |  | 53.96
Performance criteria adjustment | 12,257 |  |  | 52.96
Vested | (38,897) |  |  | 52.96
Forfeited | (1,954) |  |  | 35.40
RSUs at June 30, 2021 | 90,942 |  |  | $ | 52.71 |

The Company has recorded compensation costs for the RSAs and RSUs that are included in administrative and general operating expenses in the amount of $1.4 million and $0.5 million for the three months ended June 30, 2021 and 2020, respectively. For the six months ended June 30, 2021 and 2020, the Company has recorded compensation costs for the RSAs and RSUs in the amount of $2.7 million and $1.3 million, respectively.

Note 5. Earnings (Loss) Per Share of Common Stock
The computations of basic and diluted earnings per share of common stock are noted in the table below. Basic earnings per share of common stock is computed by dividing the net income 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. RSUs are not included in the basic and diluted shares calculation for financial reporting until authorized by the Organization & Compensation Committee of the Board of Directors.

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.

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 $95.0 million and $100.0 million as of June 30, 2021 and December 31, 2020, respectively. There were $50.0 million and $270.0 million of borrowings on the Cal Water line of credit as of June 30, 2021 and December 31, 2020, respectively. The average borrowing rate for borrowings on the Company and Cal Water lines of credit during the six months ended June 30, 2021 was 0.99% compared to 2.13% 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 table below:

| Three Months Ended June 30
| 2021 |  | 2020
Income tax expense | $ | 2,484 |  |  | $ | 1,442 |

| Six Months Ended June 30
| 2021 |  | 2020
Income tax expense (benefit) | $ | 2,741 |  |  | $ | (3,408) |

The total income tax expense increased $1.0 million to $2.5 million in the second quarter of 2021 as compared to $1.4 million in the second quarter of 2020. The increase was mainly due to an increase in pre-tax earnings which was partially offset by reduction of tax repair deduction benefits and increase in refund of excess deferred income taxes in 2021 as compared to 2020.
The total income tax expense increased $6.1 million to $2.7 million in the first six months of 2021 as compared to $3.4 million income tax benefit in the first six months of 2020. The increase was mainly due to an increase in pre-tax earnings which was partially offset by reduction of tax repair deduction benefits and increase in refund of excess federal deferred income taxes in 2021 as compared to 2020.
The Company’s effective tax rate was 6.02% before discrete items in the second quarter of 2021 as compared to 18.5% in the second quarter of 2020. The decrease in effective income tax rate was primary due to an increase in refund of the excess federal deferred taxes in 2021 as compared to 2020.
16

Table of Contents
The Company had unrecognized tax benefits of approximately $14.2 million and $12.4 million as of June 30, 2021 and 2020, respectively. Included in the balance of unrecognized tax benefits as of June 30, 2021 and 2020, is $3.8 million and $3.0 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, 2020.
17

Table of Contents
As of June 30, 2021, there were no significant changes in these commitments from December 31, 2020.
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 June 30, 2021 and December 31, 2020, the Company recognized a liability of $3.6 million and $2.6 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.
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 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 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 Company's Annual Report on Form 10-K for the year ended December 31, 2020. They include:
•revenue recognition;
•regulated utility accounting;
•income taxes;
•pension and postretirement health care benefits;
For the six months ended June 30, 2021, 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 the course of 2020 and continuing into the first six months of 2021, as a result of the COVID-19 pandemic, shelter-in-place and social distancing ordinances of varying durations and scope were implemented in all of the states in which we operate. Such governmental orders resulted in temporary closures of non-essential businesses and self-quarantining on non-essential workers. As an “essential business” during times of emergencies pursuant to the U.S. Critical Infrastructures Protection Act of 2001, we are working to continue to provide high quality water and wastewater services to our two million customers. During 2020 and for the six months ended June 30, 2021 and through July 29, 2021, the COVID-19 pandemic has not had a significant impact on our business or operations. We have, however, increased our allowance for

credit losses as we have ceased all shutoffs for non-payment during the pandemic and anticipate this situation will continue until further notice. We are expecting segments of our customer base to continue to experience employment layoffs and business closures that negatively impact their ability to pay utility bills. We have also incurred costs to promote the health and safety of our employees and facilities.
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. All 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 SECOND QUARTER 2021 OPERATIONS
COMPARED TO SECOND QUARTER 2020 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 second quarter of 2021 was $38.2 million or $0.75 earnings per diluted common share, compared to net income attributable to California Water Service Group of $5.3 million or $0.11 earnings per diluted common share for the second quarter of 2020.
The $32.9 million increase in net income attributable to California Water Service Group was primarily due to the December 2020 decision by the CPUC on Cal Water’s 2018 GRC. The decision authorized rate increases and the continuation of regulatory mechanisms that the Company had not recorded in the second quarter of 2020. Second quarter 2021 results included cumulative GRC rate relief of $7.9 million, representing 2020 and 2021 rate changes, and regulatory mechanism net revenue increases of $18.0 million in the second quarter of 2021 as compared to the second quarter of 2020. The increase in net income attributable to California Water Service Group resulting from the adoption of Cal Water's 2018 GRC was partially offset by increases in administrative and general expense of $4.8 million, depreciation and amortization expense of $2.7 million and property taxes of $0.6 million.
Additional factors outside the Company’s immediate control also significantly contributed to the increase in net income attributable to California Water Service Group, including a $10.9 million increase in accrued unbilled revenue partially offset by a $1.9 million decrease in unrealized gain on certain benefit plan investments. Seasonal weather patterns and the number of unbilled days are the primary drivers of accrued unbilled revenue.
Operating Revenue
Operating revenue increased $37.6 million, or 21.4%, to $213.1 million in the second quarter of 2021 as compared to the second quarter of 2020, with such change attributed to the following:

Net change due to rate changes, usage, and other (1) | $ | 37,533 |
WRAM Revenue (2) | 1,477 |
MCBA Revenue (3) | 6,978 |
Other balancing account revenue (4) | (793) |
Deferral of revenue (5) | (7,556) |
Net operating revenue increase | $ | 37,639 |

1.The net change due to rate changes, usage, and other in the above table was mainly driven by rate increases, the components of which are set forth in the table below, a 9.8% increase in customer usage and a $10.9 million increase in accrued unbilled revenue.

General rate case | $ | 2,306 |
Escalation rate increases | 1,970 |
Purchased water and pump tax offsets | 1,376 |
Rate base offsets | 2,273 |
Total increase in rates | $ | 7,925 |

2.WRAM revenue is the variance between adopted volumetric revenues and actual billed volumetric revenues for metered accounts. For the second quarter of 2021, we recognized $1.5 million of WRAM revenue. Actual volumetric revenue was lower than adopted volumetric billings due to a shift in customer usage from nonresidential to residential usage. Due to the delay in the resolution of the 2018 GRC, WRAM revenue was not recorded in the second quarter of 2020.
3.MCBA revenue is the variance between adopted water production costs and actual water production costs. For the second quarter of 2021, we recognized $7.0 million of MCBA revenue. Actual water production costs were higher than adopted production costs in the second quarter of 2021 due to a shift in water production mix from well water to purchased water in certain of our service territories. As required by the MCBA mechanism, the increase in actual water production costs relative to adopted water production costs in California also increased operating revenue for the same amount. Due to the delay in the resolution of the 2018 GRC, MCBA revenue was not recorded in the second quarter of 2020.
4.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 second quarter of 2021, we recognized a decrease to revenue of $0.8 million for these balancing accounts. The decrease in revenue was mainly due to a decrease in actual health care expenses relative to adopted in the second quarter of 2021. Due to the delay in the resolution of the 2018 GRC, PCBA and HCBA revenue were not recorded in the second quarter of 2020.
5.The deferral of revenue consists of amounts that are expected to be collected from customers beyond 24 months following the end of the accounting period in which these revenues were recorded. The deferral increased in the second quarter of 2021 as compared to the second quarter of 2020 due to an increase in the balancing account revenue expected to be collected beyond 24 months.
Total Operating Expenses
Total operating expenses increased $7.9 million, or 4.8%, to $170.9 million in the second quarter of 2021, as compared to $163.0 million in the second quarter of 2020.
Water production costs consists of purchased water, purchased power, and pump taxes. It represents the largest component of total operating expenses, accounting for approximately 43.8% of total operating expenses for the second quarter of 2021, as compared to 43.6% of total operating expenses for the second quarter of 2020. Water production costs increased 5.3% in the second quarter of 2021 as compared to the same period last year mainly 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 June 30
| 2021 |  | 2020
Well production | 47 | % |  | 44 | %
Purchased | 49 | % |  | 50 | %
Surface | 4 | % |  | 6 | %
Total | 100 | % |  | 100 | %

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

| Three Months Ended June 30
| 2021 |  | 2020 |  | Change
Purchased water | $ | 62,139 |  |  | $ | 59,738 |  |  | $ | 2,401 |
Purchased power | 9,171 |  |  | 8,128 |  |  | 1,043 |

Total | $ | 74,911 |  |  | $ | 71,142 |  |  | $ | 3,769 |

Administrative and general and other operations expenses decreased $0.3 million, or 0.7%, to $52.5 million in the second quarter of 2021, as compared to $52.8 million in the second quarter of 2020. The decrease was due to a $6.3 million decrease in costs associated with deferred WRAM revenue, $0.8 million decrease in uninsured loss costs, and a $0.5 million decrease in legal expense. The cost decreases were partially offset by increases in employee wages of $4.7 million, consulting and other outside service fees of $0.8 million, water treatment costs of $0.7 million, and software maintenance costs of $0.6 million. 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 up to 85% of the variance between adopted and recorded expenses.
Maintenance expense decreased $0.1 million, or 1.7%, to $6.6 million in the second quarter of 2021, as compared to $6.7 million in the second quarter of 2020, mostly due to a reduction in repairs of transmission and distribution mains.
Depreciation and amortization expense increased $2.7 million, or 11.0%, to $27.2 million in the second quarter of 2021, as compared to $24.5 million in the second quarter of 2020, mostly due to utility plant placed in service in 2020.
Income taxes increased $1.4 million to $2.0 million in the second quarter of 2021, as compared to $0.6 million in the second quarter of 2020. The increase was mainly due to an increase in operating income and reduction in state tax benefits from repair deductions of $64.0 million which was partially offset by a decrease in the 2021 effective tax rate due to a $19.4 million increase in refund of excess federal income taxes in 2021 as compared to 2020.
Property and other taxes increased $0.6 million to $7.7 million in the second quarter of 2021, as compared to $7.1 million in the same period of 2020, mostly due to an increase in assessed property values.
Other Income and Expenses
Net other income increased $3.3 million to $6.6 million in the second quarter of 2021, as compared to a net other income of $3.3 million in the second quarter of 2020, due primarily to a $4.0 million decrease in other components of net periodic benefit costs partially offset by a $1.9 million decrease in unrealized gain on certain benefit plan investments and a $0.9 million decrease in allowance for equity funds used during construction.
Interest Expense
Net interest expense increased $0.3 million, or 2.6%, to $10.8 million in the second quarter of 2021, as compared to $10.5 million in the second quarter of 2020. The increase was due primarily to an increase in financing to support the capital investment program from the 2018 GRC.

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 six months of 2021 was $35.2 million or $0.69 earnings per diluted common share, compared to net loss attributable to California Water Service Group of $15.0 million or $0.31 net loss per diluted common share for the first six months of 2020.
The $50.2 million increase in net income attributable to California Water Service Group was primarily due to the December 2020 decision by the CPUC for Cal Water’s 2018 GRC. The decision authorized rate increases and the continuation of regulatory mechanisms which the Company had not recorded during the first six months of 2020. Results for the first six months of 2021 included cumulative 2018 GRC rate relief of $14.3 million, representing 2020 and 2021 rate changes, and regulatory mechanism net revenue increases of $25.6 million for the first six months of 2021 as compared to the first six months of 2020. The increase in net income attributable to California Water Service Group resulting from the adoption of Cal Water's 2018 GRC was partially offset by increases in administrative and general expense of $5.5 million, depreciation and amortization expense of $5.3 million, and property taxes of $1.3 million.
Additional factors outside the Company’s immediate control also significantly contributed to the increase in net income attributable to California Water Service Group, including a $14.5 million increase in accrued unbilled revenue and $3.1 million increase in unrealized gain on certain benefit plan investments. Seasonal weather patterns and the number of unbilled days are the primary drivers of accrued unbilled revenue.
Operating Revenue
Operating revenue increased $59.8 million, or 19.9%, to $360.9 million for the first six months of 2021 as compared to the first six months of 2020, with such change attributed to the following:

Net change due to rate changes, usage, and other (1) | $ | 52,324 |
WRAM Revenue (2) | 705 |

3.MCBA revenue is the variance between adopted water production costs and actual water production costs. For the first six months of 2021, we recognized $11.0 million of MCBA revenue. Actual water production costs were higher than adopted production costs in the first six months of 2021 due to a shift in water production mix from well water to purchased water in certain of our service territories. As required by the MCBA mechanism, the increase in actual water production costs relative to adopted water production costs in California also increased operating revenue for the same amount. Due to the delay in the resolution of the 2018 GRC, MCBA revenue was not recorded in the first six months of 2020.
4.Due to the delay in the resolution of the 2018 GRC, the CPUC authorized Cal Water to track the effect of the delay on customer billings in an IRMA effective January 1, 2020. Variances between actual customer billings and those that would have been billed assuming the GRC had been effective January 1, 2020 are recorded as regulatory balancing account revenue. The 2018 GRC was approved in December of 2020 and final rates for the 2018 GRC were implemented as of February 1, 2021; as a result, Cal Water recorded IRMA revenue for January 2021. Due to the delay in the resolution of the 2018 GRC, IRMA revenue was not recorded in the first six months of 2020.
5.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 six months of 2021, we recognized a decrease to revenue of $2.2 million for these balancing accounts. The decrease in revenue was mainly due to a decrease of $3.6 million in actual health care expenses relative to adopted partially offset by an increase of $1.0 million in actual pension expenses relative to adopted in the first six months of 2021. Due to the delay in the resolution of the 2018 GRC, PCBA and HCBA revenue were not recorded in the first six months of 2020.
6.The deferral of revenue consists of amounts that are expected to be collected from customers beyond 24 months following the end of the accounting period in which these revenues were recorded. The deferral increased in the first six months of 2021 as compared to the first six months of 2020 due to an increase in the balancing account revenue expected to be collected beyond 24 months.

Administrative and general and other operations expenses increased $4.3 million, or 4.4%, to $100.8 million in the first six months of 2021, as compared to $96.5 million in the first six months of 2020. The increase was primarily due to a $4.3 million increase in employee wages, $1.3 million increase in uninsured losses, $1.0 million increase in water treatment costs, $0.9 million increase in software maintenance costs, and $0.6 million increase in credit loss expenses which was partially offset by a $3.6 million decrease in costs associated with deferred WRAM revenue and a $0.7 million decrease in retirement benefits. 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 up to 85% of the variance between adopted and recorded expenses.
Maintenance expense decreased $0.4 million, or 3.0%, to $13.4 million in the first six months of 2021, as compared to $13.8 million in the first six months of 2020, mostly due to a reduction in repairs of transmission and distribution mains.
Depreciation and amortization expense increased $5.3 million, or 10.7%, to $54.3 million in the first six months of 2021, as compared to $49.0 million in the first six months of 2020, mostly due to capital additions in 2020.
Income tax expense increased $5.2 million to $1.9 million in the first six months of 2021, as compared to $3.3 million income tax benefit in the first six months of 2020. The increase was mainly due to an increase in operating income and a reduction in the state tax benefit from repair deductions which was partially offset by an increase in refund of excess deferred federal income taxes in 2021 as compared to 2020.
Property and other taxes increased $1.3 million to $15.7 million in the first six months of 2021, as compared to $14.4 million in the same period of 2020, mostly due to an increase in assessed property values.
Other Income and Expenses
Net other income increased $10.9 million to $10.6 million in the first six months of 2021, as compared to a net other loss of $0.3 million in the first six months of 2020, due primarily to a $8.4 million decrease in other components of net periodic benefit costs and $3.1 million increase in unrealized gain on certain benefit plan investments due to favorable market conditions which was partially offset by a $1.9 million decrease in allowance for equity funds used during construction.
Interest Expense
Net interest expense increased $0.4 million, or 1.7%, $20.7 million in the first six months of 2021, as compared to $20.3 million in the first six months of 2021. The increase was due primarily to an increase in financing to support the capital investment program from the 2018 GRC.
REGULATORY MATTERS
2021 California Regulatory Activity
California GRC Filing
On October 14, 2020, an ALJ with the CPUC issued a proposed decision for Cal Water's 2018 GRC filing, which was approved by the CPUC on December 4, 2020. The new rates were implemented on February 1, 2021.
The CPUC follows a rate case plan, which requires Cal Water to file a GRC for each of its regulated operating districts (except Grand Oaks) every three years. In a GRC proceeding, the CPUC not only considers the utility's rate setting requests, but may also consider other issues that affect the utility's rates and operations. The CPUC is generally required to issue its GRC decision prior to the first day of the test year or authorize interim rates.
On July 2, 2021, Cal Water filed its 2021 GRC requesting water infrastructure investments of $1.0 billion in accordance with the rate case plan for all of its regulated operating districts for the years 2022, 2023, and 2024. The CPUC will evaluate the water infrastructure improvement investments along with operating budgets to establish water rates that reflect the actual cost of service. The CPUC will also evaluate Cal Water's proposed rate design changes that would improve revenue stability and provide a discounted unit rate to the first six units of water per month for residential customers. In the proposal, this block of usage would be charged at 25% of the average rate. The CPUC has recognized this six-unit block as essential for basic needs. The required filing begins an approximately 18-month review process, with any changes in customer rates expected to become effective in 2023. Cal Water has proposed to the CPUC to increase revenues by $80.5 million, or 11.1%, in 2023; $43.6 million, or 5.4%, in 2024; and $43.2 million, or 5.1%, in 2025 to support these investments. If approved as filed, this would cost the average residential customer less than an additional $5 per month across all of Cal Water’s service areas.

IRMA
The 2018 GRC was approved in December of 2020 and final rates for the 2018 GRC were implemented as of February 1, 2021; as a result, Cal Water calculated and recorded a regulatory asset of $55.7 million and a corresponding increase to revenue for the difference between final rates and interim rates for the 13-month period January 1, 2020 to January 31, 2021. Cal Water also recorded a regulatory liability of $1.6 million and a corresponding decrease to regulatory assets for LIRA and RSF program credits that would have been given to customers had the rate case been approved on time.
In April of 2021, Cal Water submitted an advice letter to request amortization of the IRMA. The new rates were implemented on April 15, 2021. In May of 2021, Cal Water submitted an advice letter to adjust the rates that were implemented on April 15, 2021. The updated rates were implemented on June 15, 2021.
2020 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 requested a return on equity of 10.35%, a cost of debt of 4.23%, and a 53.4% equity capital structure. The CPUC will evaluate the proposal along with proposals of other parties and, according to its standard process, is expected to issue a decision late in 2021.
California Drought Memorandum Account (DRMA)
In June of 2021, Cal Water submitted an advice letter 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 mandatory rationing measures, 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.
Escalation Increase Requests
As part of the decision on the 2018 GRC, Cal Water was authorized to request annual escalation rate increases for 2021 for those districts that passed the earnings test. In December of 2020, Cal Water requested escalation rate increases for 2021 in 13 of its regulated districts. The annual adopted gross revenue associated with the December 2020 filing was $8.2 million. The new rates were implemented on February 1, 2021.
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 2020, 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 $5.5 million. The new rates were implemented on February 1, 2021.
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 July of 2020, Cal Water submitted an advice letter to recover $9.0 million of annual revenue increase for a rate base offset in one of its regulated districts. The new rates were implemented on February 1, 2021.
WRAM/MCBA Filings
In April of 2021, Cal Water submitted an advice letter to true up the revenue under-collections for the 2020 annual WRAMs/MCBAs of its regulated districts. A net under-collection of $39.6 million is being recovered/refunded from/to customers in the form of 12, 18, and greather-than-18-month surcharges and 6 and 12 month surcredits. The new rates incorporate net WRAM/MCBA balances that were previously approved for recovery, and were implemented on April 15, 2021.

2015 GRC PCBA and HCBA Filings
During the first six months of 2021, Cal Water submitted advice letters to amortize the PCBA and HCBA from the 2015 GRC that tracked the difference between adopted and actual costs for the period of 2017-2019. For the PCBA, $21.3 million is being recovered from customers in the form of 12 and 24 month surcharges as actual pension costs during 2017-2019 were higher than the adopted pension costs. For the HCBA, $4.3 million is being refunded to customers in the form of 12 month surcredits as actual health care costs during 2017-2019 were lower than the adopted health care costs. The new rates were implemented on June 15, 2021.
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 as a result of the TCJA. A decision on the PLR is expected later this year.
Kapalua Water Company and Kapalua Waste Treatment (Hawaii Water)
In the first quarter of 2021, Hawaii Water Service received approval from the Hawaii Public Utilities Commission (HPUC) to acquire the assets of Kapalua Water Company and Kapalua Waste Treatment Company from Maui Land and Pineapple Company. Hawaii Water took control of the water and wastewater systems on May 1, 2021.
HOH Utilities Company (Hawaii Water)
In June of 2021, Hawaii Water signed an agreement to acquire the assets of HOH Utilities Company, a wastewater utility located in the growing Poipu/Koloa area of Kauai County on the island of Kauai. The acquisition is subject to satisfaction of customary closing conditions, including approval by the HPUC.
Hawaii Water is expected to own and manage the wastewater utility, which currently serves almost 1,800 residential, commercial, and resort customers in Poipu and Koloa, including three hotels, condominiums, multi-family housing, a golf course, and single-family homes.
BVRT Utility Holding Company (BVRT) (Texas Water)
In May of 2021, Texas Water became the majority owner of BVRT, a Texas-based utility development company owning and operating four wastewater utilities serving growing communities outside of Austin and San Antonio. Texas Water initially invested funds to enable BVRT to continue to build wastewater infrastructure and converted its investment to equity. BVRT’s four wastewater utilities currently serve or are under contract to serve over 2,500 connections, with an estimated potential total build-out of more than 61,000 connections.
LIQUIDITY
Cash flow from Operations
Cash flow from operations for the first six months of 2021 was $67.7 million compared to $20.0 million for the same period in 2020. The increase in the first six months of 2021 as compared to 2020 was primarily due to the delay in the resolution of the 2018 GRC. Due to the delay, we did not meet the recognition criteria to recognize $4.1 million of rate relief and $25.6 million of regulatory mechanism net revenue in the first six months of 2020. Cash generated by operations varies during the year due to customer billings, and timing of collections and contributions to our benefit plans.
During the first six months of 2021, we made contributions of $14.1 million to our employee pension plan compared to contributions of $16.8 million during the first six months of 2020. During the first six months of 2021, we made contributions of $1.5 million to the other postretirement benefit plans compared to contributions of $3.9 million during the first six months of 2020. The full-year 2021 estimated cash contribution to the pension plans and other postretirement benefits plans are expected to be approximately $23.5 million and $2.2 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.

Investing Activities
During the first six months of 2021 and 2020, we used $138.5 million and $133.5 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 2021, we estimate utility plant expenditures to be between $270.0 million and $300.0 million.
Financing Activities
Net cash provided by financing activities was $98.7 million during the first six months of 2021 compared to $222.8 million of net cash provided by financing activities for the same period in 2020. For 2021, this includes our issuance of $280.0 million of First Mortgage Bonds, $61.6 million of Company common stock through our at-the-market equity program, and $1.0 million through our employee stock purchase plan. For 2020, this includes our issuance of $37.1 million of Company common stock through our at-the-market equity program and $0.9 million through our employee stock purchase plan.
During the first six months of 2021 and 2020, we borrowed $125.0 million and $270.0 million, respectively, on our unsecured revolving credit facilities. We made a repayment on our unsecured revolving credit facilities of $350.0 million and $70.0 million during the first six months of 2021 and 2020, respectively.
The undercollected net WRAM and MCBA receivable balances were $67.5 million and $52.6 million as of June 30, 2021 and 2020, 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, 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 six months of 2021, we utilized cash generated from operations, borrowings on the unsecured revolving credit facilities, issuance of First Mortgage Bonds, and cash received from the sale of Company common stock through our at-the-market equity program 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 June 30, 2021 and December 31, 2020, there were short-term borrowings of $145.0 million and $370.0 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, 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 June 30, 2021, 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.

Dividends
During the first six months of 2021, our quarterly common stock dividend payments were $0.4600 per share compared to $0.4250 per share during the first six months of 2020. For the full year 2020, the payout ratio was 43.1% 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.

Table of Contents
At the July 28, 2021 meeting, the Company's Board of Directors declared the third quarter dividend of $0.2300 per share payable on August 20, 2021, to stockholders of record on August 9, 2021. This was our 306th consecutive quarterly dividend.
2021 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 June 30, 2021, the Company’s and Cal Water’s availability on these unsecured revolving lines of credit was $55.0 million and $350.0 million, respectively.
On May 11, 2021, Cal Water completed the sale and issuance of $280.0 million in aggregate principal amount of First Mortgage Bonds in a private placement and used the net proceeds from the sale to refinance existing indebtedness and for general corporate purposes.
Book Value and Stockholders of Record
Book value per common share was $19.25 at June 30, 2021 compared to $18.30 at December 31, 2020. There were approximately 1,932 stockholders of record for our common stock as of May 10, 2021.
Utility Plant Expenditures
During the first six months of 2021, utility plant expenditures totaled $138.5 million for Company-funded and developer-funded projects. For 2021, we estimate utility plant expenditures to be between $270.0 million and $300.0 million. We do not control third-party-funded utility plant expenditures and therefore are unable to estimate the amount of such projects for 2021.
As of June 30, 2021, construction work in progress was $216.0 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 5.8 billion gallons or 12.3% 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 27.5 billion gallons or 58.0% of our total annual water supply pumped from wells. Our annual groundwater extraction from unmanaged groundwater basins approximates 14.1 billion gallons or 29.7% of our total annual water supply pumped from wells. Most of the managed groundwater basins we extract water from have groundwater recharge facilities. We are required to pay well pump taxes to financially support these groundwater recharge facilities. Our well pump taxes were $3.6 million and $3.3 million for the three months ended June 30, 2021 and 2020, respectively. For the six months ended June 30, 2021 and 2020 our well pump taxes were $7.2 million and $6.1 million, 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

Table of Contents
fill reservoirs, providing the water supply for subsequent delivery to customers. As of June 30, 2021, the State of California snowpack water content during the 2021-2022 water year is 5% 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 0% and 0%, 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 2021 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 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 six months ended June 30, 2021, 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.
32

Table of Contents
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 June 30, 2021. Based on that evaluation, we concluded that our disclosure controls and procedures were effective at the reasonable assurance level.
(b) Changes to Internal Control over Financial Reporting
There was no change in our internal controls over financial reporting that occurred during the quarter ended June 30, 2021, 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.
