(a) The adjustments 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 first six months ended June 30, 2020 were recorded in the three months ended September 30, 2020 as the Company received a proposed decision for its 2018 General Rate Case for Cal Water (2018 GRC) in October of 2020. The Company also recorded an adjustment for its interim rate memorandum account (IRMA) where it was authorized to track the effect of the delay in the resolution of the 2018 GRC on customer billings.

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 condensed consolidated balance sheets, is inconsequential.

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:

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.

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 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. In the third quarter of 2020, Cal Water determined that the IRMA met regulatory asset recognition criteria under accounting standards for regulated utilities.

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.

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.

Lease revenue is not considered revenue from contracts with customers and is recognized following operating lease standards. The Company is the lessor in operating lease agreements with telecommunications companies under which cellular phone antennas are placed on the Company's property.

The Company 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 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.

During the third quarter of 2020, 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 April 1, 2021. 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.

In June of 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which changed the impairment model for certain financial assets that have a contractual right to receive cash, including trade and loan receivables. The new model required recognition based upon an estimation of expected credit losses rather than recognition of losses when it is probable that they have been incurred. ASU 2016-13 was effective for annual reporting periods beginning after December 15, 2019, with early adoption permitted. The Company adopted the standard utilizing the modified retrospective method for its trade receivables and unbilled revenue on January 1, 2020. Based on the composition of the Company’s trade receivables and unbilled revenue, and expected future losses, the adoption of ASU 2016-13 did not have a material impact on its consolidated financial statements.

In January of 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, which eliminated the second step of the goodwill impairment test that required a hypothetical purchase price allocation to measure goodwill impairment. Under the new guidance, a goodwill impairment loss will be measured at the amount by which a reporting unit’s carrying amount exceeds its fair value, not to exceed the carrying amount of goodwill. ASU 2017-04 was effective for annual reporting periods beginning after December 15, 2019, with early adoption permitted for any impairment test performed on testing dates after January 1, 2017. The Company adopted the standard on January 1, 2020 and the adoption of the standard did not have a material impact on its consolidated financial statements.

In August of 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure for Fair Value Measurement, which modified the disclosure requirements on fair value measurements. The modifications in this update eliminated, amended, and added disclosure requirements for fair value measurements. ASU 2018-13 was effective for annual reporting periods beginning after December 15, 2019, with early adoption permitted. The Company adopted the standard in part prospectively and in part retrospectively, in accordance with the requirements of ASU 2018-13, on January 1, 2020. Since the Company does not have level 3 fair value measurements or transfers between level 1 and level 2 fair value measurements, the adoption of the standard did not have a material impact on its footnote disclosures.
