The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) and include the accounts of SJW Group, its wholly owned subsidiaries, and two variable interest entities in which two SJW Group subsidiaries are the primary beneficiaries. The accounting policies of SJW Group’s subsidiaries comply with the applicable uniform system of accounts prescribed by the respective regulators. All intercompany transactions and balances have been eliminated in consolidation. The accounting policies of SJW Group’s subsidiaries comply with the applicable uniform system of accounts prescribed by the respective regulators and conform to generally accepted accounting principles for rate-regulated public utilities. SJW Group’s subsidiaries are as follows:

San Jose Water Company (“SJWC”), is a regulated California water utility providing water service to approximately 231,000 connections that serve approximately one million people in the greater metropolitan San Jose area. Approximately 93% of SJWC’s revenues are derived from the sale of water to residential and business customers.

SJWNE is a special purpose entity holding company for SJW Group’s investment in Connecticut Water Service, Inc. (“CTWS”) which was acquired on October 9, 2019. CTWS, headquartered in Connecticut, is a holding company for water utilities companies providing water service to approximately 139,000 connections that serve a population of approximately 485,000 people in 81 municipalities throughout Connecticut and Maine and more than 3,000 wastewater connections in Southbury, Connecticut. As part of the merger transaction between SJW Group and CTWS on October 9, 2019, CTWS became a wholly-owned subsidiary of SJWNE LLC which is a wholly-owned subsidiary of SJW Group (see, Note 12, “Business Combinations”). The subsidiaries held by CTWS that provide utility water services are The Connecticut Water Company (“Connecticut Water”) and The Maine Water Company (“Maine Water”). The remaining two subsidiaries are Chester Realty, Inc., a real estate company in Connecticut, and New England Water Utility Services, Inc. (“NEWUS”), which provides contract water and sewer operations and other water related services. Effective September 30, 2020, The Heritage Village Water Company (“HVWC”) and The Avon Water Company (“Avon Water”) merged into Connecticut Water after receiving the merger approval from the Connecticut Public Utilities Regulatory Authority (“PURA”).

SJWTX, Inc. is incorporated in the State of Texas and is doing business as Canyon Lake Water Service Company (“CLWSC”). CLWSC is a public utility in the business of providing water service to approximately 59,000 people. CLWSC’s service area comprises more than 247 square miles in the southern region of the Texas Hill Country in Blanco, Comal, Hays and Travis counties, the growing region between San Antonio and Austin, Texas. SJWTX, Inc. has a 25% interest in Acequia Water Supply Corporation. Acequia has been determined to be a variable interest entity within the scope of ASC Topic 810 with SJWTX, Inc. as the primary beneficiary. As a result, Acequia has been consolidated with SJWTX, Inc.

SJW Land Company owns a commercial property and undeveloped real estate property in the states of California and Tennessee and owns and operates commercial properties in the state of Tennessee. SJW Land also has a 70% limited partnership interest in 444 West Santa Clara Street, L.P. 444 West Santa Clara Street, L.P. has been determined to be a variable interest entity within the scope of ASC Topic 810 with SJW Land Company as the primary beneficiary. As a result, 444 West Santa Clara Street L.P. has been consolidated with SJW Land Company. In 2017, 444 West Santa Clara Street, L.P. sold all of its interests in the commercial building and land the partnership owned and operated. The limited partnership is expected to dissolve in 2021. Results of operations and balances of the non-controlling interest are not material to the consolidated financial statements (see below in Note 1, “Real Estate Investments”).

In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,” and subsequent amendments. Topic 326 requires measurement and recognition of expected credit losses for financial assets held. ASU 2016-13 was effective for SJW Group in the first quarter of fiscal 2020. The adoption of ASU 2016-13 did not have a material impact on the consolidated financial statements.

In August 2018, the FASB issued Accounting Standards Update (“ASU”) 2018-14, “Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20: “Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans,” which aims to improve the overall usefulness of disclosure to financial statement users and reduce unnecessary costs to companies when preparing defined benefit plan disclosures. This update was effective for SJW Group’s Form 10-K for the year ending December 31, 2020. Retrospective adoption is required and early adoption is permitted. The adoption of ASU 2018-14 did not have a material impact on the condensed consolidated financial statements.

In December 2019, the FASB issued ASU 2019-12, “Simplifying the Accounting for Income Taxes”, which simplifies the accounting for income taxes, eliminates certain exceptions within Topic 740, “Income Taxes”, and clarifies certain aspects of the current guidance to promote consistency among reporting entities. This update is effective for fiscal years beginning after December 15, 2021. Most amendments within the standard are required to be applied on a prospective basis, while certain amendments must be applied on a retrospective or modified retrospective basis. Management is currently evaluating the impacts of the provisions of ASU 2019-12 on the consolidated financial statements.

The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America 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 date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

For the years 2020, 2019 and 2018, depreciation expense as a percent of the beginning of the year balance of depreciable plant was approximately 3.2%, 3.8% and 3.6%, respectively. Depreciation expense for utility plant for the years ended December 31, 2020, 2019 and 2018 was $86,823, $63,785 and $53,031, respectively. For the years 2020, 2019 and 2018, the amounts allocated to administrative and general expense were $2,343, $2,869 and $2,306, respectively. The cost of utility plant retired, including retirement costs (less salvage), is charged to accumulated depreciation and no gain or loss is recognized.

AFUDC represents the capitalized costs of borrowed funds or a return on equity funds used to finance utility plant under construction and is capitalized as part of construction work in progress. AFUDC is recorded to the extent approved by the respective states’ utility regulators and is recovered through water rates as the utility plant depreciates. The amount of interest capitalized in 2020, 2019 and 2018 was $4,133, $4,323 and $2,856, respectively. Interest on long-term debt is presented net of amounts capitalized on the Consolidated Statement of Comprehensive Income. The amount of equity funds capitalized in 2020 was $1,249, reflected in “Other, net” on the Consolidated Statement of Comprehensive Income. Prior to the merger with CTWS on October 9, 2019, SJW Group did not have AFUDC for equity funds.

Real estate investments are recorded at cost and consist primarily of land and buildings. Net gains and losses from the sale of real estate investments are recorded as a component of other (expense) income in the Consolidated Statements of Comprehensive Income. Nonutility property in Water Utility Services is also classified in real estate investments. Nonutility property is property that is neither used nor useful in providing water utility services to customers and is excluded from rate base for rate-setting purposes. SJWC recognizes gain/loss on disposition of nonutility property in accordance with California

Public Utilities Commission (“CPUC”) Code Section 790, whereby the net proceeds are reinvested back into property that is useful in providing water utility services to customers. CTWS and CLWSC do not have regulatory restrictions on the use of proceeds from the sale of nonutility property. There is no depreciation associated with Water Utility Services nonutility property as it is all undeveloped land.

On December 19, 2019, Maine Water completed the second half of a previously announced land sale with the Coastal Mountains Land Trust, Maine nonprofit corporation. The transaction was structured such that Maine Water sold a conservation easement valued at $1,200 for $600. Accordingly, Maine Water expects to claim a $600 charitable deduction for federal and state income tax purposes on the bargain sale. The MPUC has previously ruled that the net proceeds from the transaction will be shared equally between the customers of the Camden Rockland division and Maine Water. The transaction generated approximately $180 in pre-tax gain on sale of nonutility property at Maine Water. Additionally, Connecticut Water disposed of a small parcel of land generating an additional $4 in pre-tax gain on sale of nonutility property.

On April 22, 2019, all creek repairs were completed for a commercial building and land SJW Land sold in 2017 and a reimbursement of $745 was provided to a SJW Land partnership. SJW Land Company and the noncontrolling interest recognized a pre-tax gain on the creek reimbursement of $521 and $224, respectively, on the transaction.

Real estate investments include $57,273 and $56,839 as of December 31, 2020 and 2019, respectively, of assets that are leased or available for lease. The following schedule shows the future minimum rental payments to be received from third parties under operating leases that have remaining noncancelable lease terms in excess of one year as of December 31, 2020:

SJW Group applies the provisions of ASC Topic 805—“Business Combinations” for the purchase accounting related to the merger with CTWS on October 9, 2019. Topic 805 requires SJW Group to recognize separately from goodwill the assets acquired and the liabilities assumed at the acquisition date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair values of the assets acquired and the liabilities assumed. While SJW Group used our best estimates and assumptions to accurately value assets acquired and liabilities assumed at the acquisition date, our estimates were inherently uncertain and subject to refinement. As a result, during the one year measurement period from the acquisition date, we recorded adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments were recorded to our Consolidated Statements of Comprehensive Income. Accounting for business combinations requires SJW Group to make significant estimates and assumptions, especially at the acquisition date, including estimates for intangible assets, contractual obligations assumed and pre-acquisition contingencies. Although SJW Group believes that the assumptions and estimates we make are reasonable and appropriate, they are based in part on historical experience and information obtained from CTWS’s management

and are inherently uncertain. Events and circumstances may occur that may affect the accuracy or validity of such assumptions, estimates or actual results. The purchase price allocation process requires management to make significant estimates and assumptions with respect to intangible assets. Although SJW Group believes the assumptions and estimates made are reasonable, they are based in part on historical experience, market conditions and information obtained from management of the acquired companies and are inherently uncertain. Examples of critical estimates in valuing certain of the intangible assets we have acquired include, but are not limited to: future expected cash flows from services; historical and expected customer attrition rates and anticipated growth in revenue from acquired customers; the expected use of the acquired assets; and discount rates. See Note 12, “Business Combination” for further discussion on the CTWS transaction.

In accordance with the requirements of FASB ASC Topic 360—“Property, Plant and Equipment,” the long-lived assets of SJW Group are reviewed for impairment when changes in circumstances or events require adjustments to the carrying values of the assets. When such changes in circumstances or events occur, the company assesses recoverability by determining whether the carrying value of such assets will be recovered through the undiscounted expected future cash flows. To the extent an impairment exists, the asset is written down to its estimated fair value with a corresponding charge to operations in the period in which the impairment is identified. Long-lived assets consist primarily of utility plant in service, goodwill, regulatory assets, real estate investments and intangible assets. SJW Group first performs a qualitative assessment to determine whether it is necessary to perform the quantitative impairment test. In assessing the qualitative factors, SJW Group considers the impact of these key factors: change in industry and competitive environment, financial performance, and other relevant Company-specific events. If SJW Group determines that as a result of the qualitative assessment it is more likely than not (> 50% likelihood) that the fair value is less than carrying amount, then a quantitative test is performed. No impairments occurred during 2020, 2019 or 2018.

Goodwill represents the excess of the purchase price paid over the estimated fair value of the assets acquired and liabilities assumed in the acquisition of a business. Goodwill is not amortized but is tested for impairment annually on October 1st or more frequently if an event occurs or circumstances change that would more likely than not, reduce the fair value of a reporting unit below its carrying amount. SJW Group first performs a qualitative assessment to determine whether it is necessary to perform the quantitative impairment test. In assessing the qualitative factors, SJW Group considers the impact of these key factors: change in industry and competitive environment, financial performance, macroeconomic conditions, and other relevant Company-specific events. If SJW Group determines that as a result of the qualitative assessment it is more likely than not (> 50% likelihood) that the fair value is less than carrying amount, then a quantitative test is performed. SJW Group’s goodwill is primarily associated with the recent merger with CTWS on October 9, 2019. As of October 1, 2020, SJW Group performed a qualitative assessment and found no indicators of impairment and therefore did not perform the quantitative impairment test. No impairments occurred during 2020, 2019 or 2018.

Cash and cash equivalents primarily consist of cash on deposit with banks with maturities of three months or less from the date of purchase. Restricted funds consist of proceeds from a Maine state revolving fund bond issuances to Maine Water of $5,000 and $4,000 on December 19, 2019 and December 23, 2020, respectively for capital expenditures. Proceeds are held by a trustee for the bonds and as funding conditions are met, funds are released. In the first quarter of 2020, all the proceeds from the December 19, 2019 bond were released by the trustee.

The following instruments are not measured at fair value on the company’s consolidated balance sheets but, require disclosure of fair values: cash and cash equivalents, accounts receivable and accounts payable. The estimated fair value of such instruments approximates their carrying value as reported on the consolidated balance sheets. The fair value of such financial instruments are determined using the income approach based on the present value of estimated future cash flows. The fair value of these instruments would be categorized as Level 2 in the fair value hierarchy, with the exception of cash and cash equivalents, which would be categorized as Level 1. The fair value of long-term debt is discussed in Note 4, “Long-Term Debt” and pension plan assets in Note 9, “Benefit Plans”.

SJW Group has investments in company owned life insurance which are valued at cash surrender value of the policies as reported by the insurer. These contracts are based principally on a referenced pool of investment funds that actively redeem shares, are observable and measurable, and are presented in “Other investments” on SJW Group’s consolidated balance sheets. As of December 31, 2020 and 2019, the value of the company owned life insurance was $8,026 and $7,086, respectively, of which $4,311 and $3,829, respectively, was related to assets to fund CTWS’ supplemental retirement plan agreements. See discussion on pension plans in Note 9, “Benefit Plans”.

Generally, there are three types of rate adjustments that affect SJWC’s revenue collection: general rate adjustments, cost of capital adjustments, and offset rate adjustments. General rate adjustments are authorized in general rate case decisions, which usually authorize an initial rate adjustment followed by two annual escalation adjustments. General rate applications are normally filed and processed during the last year covered by the most recent general rate case as required by the CPUC in order to avoid any gaps in regulatory decisions on general rate adjustments.

The purpose of an offset rate adjustment is to compensate utilities for changes in specific pre-authorized offsettable capital investments or expenses, primarily for purchased water, groundwater extraction, purchased power and pensions. Pursuant to Section 792.5 of the California Public Utilities Code, a balancing account must be maintained for each expense item for which such revenue offsets have been authorized. Memorandum accounts track revenue impacts due to catastrophic events, certain unforeseen water quality expenses related to new federal and state water quality standards, energy efficiency, water conservation during periods of mandated water restrictions, water tariffs and other approved activities or as directed by the CPUC. The purpose of a balancing and memorandum account is to track the under-collection or over-collection associated with such expense changes and activities for future recovery consideration.

On January 22, 2020, SJWC, along with three other California water utilities, filed a joint request for a one-year deferment on the Cost of Capital filings which would otherwise be due on May 1, 2020. Postponing the filing one year would alleviate administrative processing costs on the utilities as well as the CPUC staff, and provide relief for both CPUC and utility resources already strained by numerous other proceedings. The request was conditioned on no changes to the current Water Cost of Capital Mechanism in place during the one-year deferment. On March 11, 2020, the CPUC approved the request.

On March 17, 2020, the CPUC ordered its regulated water utilities to halt customer disconnection activities in connection with the COVID-19 pandemic. On April 2, 2020, Governor Gavin Newsom issued Executive Order N-42-20 suspending customer disconnection activities until further notice. On April 16, 2020, the CPUC issued Resolution M-4842 directing utilities to implement emergency customer protections to assist customers such as waiving reconnection deposits, offering payment arrangements, and suspending disconnections for nonpayment. This resolution is effective for up to one year, or April 15, 2021, with the option to extend. On February 11, 2021, the CPUC approved extending customer protections required in Resolution M-4842 through June 30, 2021, through approval of Resolution M-4849 . The resolution also requires water utilities to develop a transition plan regarding shutoffs and terminations with customers once the moratorium ends. SJWC is currently working on such plan.

On March 19, 2020, SJWC filed Advice Letter 546 to extend customer protections listed in the company’s Disaster Relief Customer Protections and Outreach Plan as required by the CPUC in response to the COVID-19 pandemic. The filing also activated SJWC’s Catastrophic Event Memorandum Account (“CEMA”) to track costs related to SJWC’s response which includes labor and materials, increases in bad debt from the suspension of shutoffs for non-payment, waived deposits and reconnection fees, and divergence from actual versus authorized usage. The customer protections and CEMA were approved effective March 4, 2020. SJWC anticipates requesting recovery of the COVID-19 pandemic response costs in a future general rate case or other filings.

On January 4, 2021, SJWC filed General Rate Case Application No. 21-01-003 requesting authority for an increase of revenue of $51,585 or 13.35% in 2022, $16,932 or 3.88% in 2023, and $19,195 or 4.24% in 2024. The application also includes requests to recover $18,499 from balancing and memorandum accounts, authorization for a $435,000 capital budget, further alignment between actual and authorized usage, and a shift to greater revenue collection in the service charge. The application will undergo a year-long review process and the new rates, if approved, are expected to be effective January 1, 2022.

On January 5, 2021, SJWC, along with three other California water utilities, filed a joint request for another one-year deferment on the Cost of Capital filings which would otherwise be due on May 1, 2021. Postponing the filing another year would alleviate administrative processing costs on the utilities as well as the CPUC staff, and provide relief for both CPUC and utility resources already strained by numerous other proceedings and COVID-19. The request is conditioned on no changes to the

PURA allows the Connecticut regulated operations to add surcharges to customers’ bills in order to recover certain costs associated with approved eligible capital projects through the Water Infrastructure Conservation Adjustment (“WICA”) in between full rate cases, as well as approved surcharges for the Water Revenue Adjustment (“WRA”).

Connecticut Water and the HVWC division mitigate the risk associated with changes in demand through a PURA approved WRA mechanism. The WRA is used to reconcile actual water demands with the demands projected in the most recent general rate case and allows companies to implement a surcharge or surcredit as necessary to recover the revenues approved in the general rate case. The WRA removes the financial disincentive for water utilities to develop and implement effective water conservation programs. The WRA allows water companies to defer on the balance sheet, as a regulatory asset or liability, for later collection from or crediting to customers the amount by which actual revenues deviate from the revenues allowed in the most recent general rate proceedings, including WICA proceedings. Projects eligible for WICA surcharges include certain types of aging utility plant, primarily water mains, meters, and service lines. Additionally, certain energy conservation projects, improvements required to comply with streamflow regulations, and improvements to acquired systems are eligible for WICA surcharges.

As of December 31, 2020, WICA surcharges for Connecticut Water and the Avon Water division were 5.75% and 9.31%, respectively. The HVWC division did not have an approved WICA surcharge. On January 28, 2020, Connecticut Water filed a WICA application representing an additional 2.6% surcharge, for a cumulative WICA surcharge of 5.84%. Additionally, on February 7, 2020, Connecticut Water and the Avon Water division separately filed their annual WICA reconciliations which called for 0.09% and 0.05% reductions of the WICA surcharges, respectively. On March 25, 2020, in separate decisions, PURA approved a net cumulative 5.75% surcharge for Connecticut Water and a net cumulative 9.26% WICA surcharge for the Avon Water division, both of which became effective on customers’ bills on April 1, 2020. On October 28, 2020, Connecticut Water filed a WICA application representing an additional 1.11% surcharge or approximately $956 increase in revenues, for a cumulative WICA surcharge of 6.94% which is scheduled to become effective April 1, 2021.

On January 15, 2021, Connecticut Water filed an application with PURA to amend rates for its customer, including those of former AWC and HVWC companies. The filing requests an increase of $20,206 in annual revenues that includes more than $265,514 in completed infrastructure investments that are not currently in approved rates and surcharges. The proposed increase will be applied across the company but may differ by rate divisions, meter size and between customer rate categories, i.e. for residential, commercial, industrial, etc. users. The application also reflects the costs of operating and maintaining the utility, including expenditures on power and treatment additives that have increased since the company’s last general rate case in 2010. PURA has 200 days from the filing to review the application, and the approved rates will go into effect soon thereafter.

On March 12, 2020, PURA issued Docket No. 20-03-15 to establish a State of Emergency Utility Shut-off Moratorium for the COVID-19 pandemic. The moratorium ordered regulated utility companies to refrain from terminating utility service to residential customers, except for safety reasons until August 1, 2020, or until such other time as determined by the PURA. The moratorium was extended through October 1, 2020 at which time the company was permitted to resume standard collection practices until or unless there is further action by PURA. In the same docket, PURA directed the public service companies to offer COVID-19 payment plans for the duration of the Governor’s Emergency Order (currently through April 20, 2021), and allow customers up to 24 months for payment arrangements on their water bills. The docket directs the public service companies to maintain a detailed record of costs incurred and revenues lost as a result of implementing its orders in the docket and allows for the establishment a regulatory asset to track incurred costs. Approval for recovery of additional costs incurred and/or revenues lost relating to the COVID-19 pandemic would be considered for recovery in the Connecticut Water’s next general rate case proceeding.

CLWSC’s rates are subject to the economic regulation of the Public Utilities Commission of Texas (“PUCT”). The PUCT authorize rate increases after the filing of an Application for a Rate/Tariff Change. Rate cases may be filed as they become necessary, provided there is no current rate case outstanding. Further, rate cases may not be filed more frequently than once every 12 months.

Maine Water’s rates, service and other matters affecting its business are subject to regulation by the Maine Public Utilities Commission (“MPUC”). As with the Connecticut regulated operations, rate relief is sought as necessary to enable the company to achieve an authorized rate of return. MPUC approves Maine Water’s rates on a division-by-division basis in Maine and allows Maine Water to add surcharges to customers’ bills in order to recover certain costs associated with capital projects through the Water Infrastructure Surcharge (“WISC”) in between general rate cases. Projects eligible for WISC surcharges include all infrastructure replacement or repair projects, excluding meters, that are necessary for the transmission, distribution or treatment of water.

In 2015, a WRA mechanism law in Maine became available to regulated water utilities. Maine’s rate-adjustment mechanism could provide revenue stabilization in divisions with declining water consumption and Maine Water expects to request usage of this mechanism in future rate filings when consumption trends support its use.

On January 20, 2020, Maine Water filed Water Infrastructure Surcharge (“WISC”) applications with the MPUC in four divisions requesting an increase between 1.76% and 3.00%, representing approximately $371 in additional revenues. The WISC application was approved on February 26, 2020 and the surcharges were effective March 1, 2020.

On March 16, 2020, MPUC issued an emergency moratorium on utility disconnection activities in connection to the COVID-19 pandemic. The moratorium directed public utility companies not to engage in any disconnection activities including disconnection notices for all classes of customers until further notice from MPUC. Maine Water is tracking COVID-19 related costs for potential future recovery in rates charged to customers. On September 17, 2020, the MPUC issued an order lifting the moratorium on utility disconnections in Maine effective November 1, 2020. The Order requires specific notifications by utilities to their customers prior to resuming disconnection activities and requires a waiver of late payment fess for customers who enter into payment arrangements on or before December 31, 2020. Maine Water is providing customer notices as required and resumed utility disconnections in November, 2020.

In California, the CPUC has established a balancing account mechanism for the purpose of tracking the under-collection or over-collection associated with expense changes and the revenue authorized by the CPUC to offset those expense changes. SJWC also maintains memorandum accounts to track revenue impacts due to catastrophic events, certain unforeseen water quality expenses related to new federal and state water quality standards, energy efficiency, water conservation, water tariffs, and other approved activities or as directed by the CPUC.

CPUC approved Advice Letter No. 548A for the recovery of the Hydro Generation Research, Development and Demonstration Memorandum Account (“PRVMA”) on August 27, 2020. Advice Letter No. 548A allowed recovery of $1,219 which was recognized as a regulatory asset for the year ended December 31, 2020. The amounts have been reflected in the PRVMA balances shown in the table below.

In response to the California Governor’s Emergency Declaration on March 4, 2020, CPUC Resolution M-4842 authorized water utilities to activate a COVID-19 CEMA with the same effective date. The CEMA was activated for SJWC through the filing of Advice Letter 546 on March 19, 2020. The account tracks savings and costs from COVID-19 related activities as well as uncollectibles beyond the authorized bad debt in the general rate case. SJWC has determined that future recovery of the account is probable and recognized regulatory assets of $2,266 in the COVID-19 CEMA for the year ended December 31, 2020. The amounts have been reflected in the CEMA balances shown in the table below.

On December 19, 2019, the CPUC denied the recovery of the 2018 Water Conservation Memorandum Account (“WCMA”) in Advice Letter No. 532 and no longer approved the tracking of WCMA balances. Due to the decision, SJWC determined it no longer met the probability criteria under ASC Topic 980-605-25 for the 2018 WCMA and recognized a reduction to regulatory assets of $9,386 for the year ended December 31, 2019.

SJWC recognized regulatory assets of $1,182 due to lost revenues accumulated in the 2017 WCMA account which represented the relief of the $1,169 reserve and interest earned on the balance during the year ended December 31, 2018. The reserve had represented the estimated amount that may not be collected within the 24-month period defined in the guidance.

A cost of capital memorandum account was approved by the CPUC on March 14, 2018. The account tracks the difference between current water rates and the lower rates adopted in the cost of capital decision issued on March 22, 2018. SJWC recorded a regulatory liability of $1,379 in the cost of capital memorandum account for the year ended December 31, 2018 with a corresponding reduction to revenue. The amount has been reflected in the 2018 cost of capital memorandum account balance shown in the table below.

The CPUC directed SJWC to establish a memorandum account to capture all of the impacts of the Tax Act including the benefit of the reduction in the federal statutory income tax rate from 35% to 21% on its regulated revenue requirement. The CPUC has indicated that the net benefit from implementing the new law should ultimately be passed on to ratepayers. The benefits associated with regulatory activities is expected to flow back to customers as directed by the CPUC, with no impact to net income. Per Advice Letter 522A filed with the CPUC, the benefit of the reduction in the federal statutory income tax rate from 35% to 21% were reflected in the customer bills effective July 1, 2018. As such, the tax memorandum account only includes the benefit of the reduction in the federal statutory income tax rate through June 30, 2018. The other impacts of the Tax Act were recorded in the tax memorandum account for the entire year. Accordingly, SJWC recorded a regulatory liability of $6,504 in the tax memorandum account for the for the year ended December 31, 2018 with a corresponding reduction to revenue. The amount has been reflected in the tax memorandum account balance shown in the table below. Refunds for tax memorandum account balances began on January 27, 2020.

On December 28, 2018, SJWC’s GRC with the CPUC was approved with new rates effective on January 1, 2019. As part of the GRC decision, $27,045 of balancing and memorandum accounts were also approved for recovery over a 12-month period at $0.5894 per centum cubic feet surcharge effective on January 1, 2019. For the year ended December 31, 2020 and 2019, SJWC collected $151 and $25,108, respectively, in surcharges for the approved recovery. Recovery of this surcharge ended in January 2020 and the remaining uncollected balance will be filed in the next general rate case.

Water Utility Services recognizes regulatory assets and liabilities for amounts that are deemed probable of recovery from, or refund to, customers. Determining probability requires significant judgement by management and includes assessing evidence that may exist prior to regulatory authorization, including regulatory rules and decisions, historical ratemaking practices, and other facts and circumstances that would indicate that recovery or refund is probable.

If the utility determined that it is no longer probable that regulatory assets would be recovered or reflected in future rates, or if the utility ceased to be subject to rate regulation, the regulatory assets would be charged against income in the period in which that determination was made. If regulatory accounting did not apply, the utility’s future financial results could become more volatile as compared to historical financial results due to the differences in the timing of expense or revenue recognition.

Rate-regulated enterprises are required to charge a regulatory asset to earnings if and when it is determined that the asset is no longer probable of recovery. SJW Group continually evaluates the recoverability of regulatory assets by assessing whether the amortization of the balance over the remaining life can be recovered through expected and undiscounted future cash flows.

(b)WRA is a Connecticut Water decoupling mechanism that qualifies as an alternative revenue program. It is used to reconcile actual water demands with the demands projected in the most recent general rate case and allows companies to implement a surcharge or surcredit as necessary to recover the revenues approved in the general rate case.

Income taxes are accounted for using the asset and liability method. Deferred tax assets and liabilities are recognized for the effect of temporary differences between financial and tax reporting. Deferred tax assets and liabilities are measured using current tax rates in effect. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the period that includes the enactment date.

In California, advances for construction received after 1981 are primarily refunded ratably over 40 years. In Connecticut and Maine, advances for construction are refunded as services are connected to the main, over periods not exceeding 15 years and in Texas non-refundable. Estimated refunds for the next five years and thereafter are shown below:

As of December 31, 2020, advances for construction was $125,027 of which $29,117 was related to non-refundable advances for construction and $28,456 was related to advances which are refunded based on service connections made. As of December 31, 2020 and 2019, the fair value of the advances for construction refunded ratably over 40 years is $50,391 and $50,035, respectively.

Customer advances and contributions in aid of construction received subsequent to 1986 and prior to June 12, 1996 generally must be included in federal taxable income, except for CTWS. Taxes paid relating to advances and contributions are recorded as deferred tax assets for financial reporting purposes and are amortized over 40 years for advances and over the tax depreciable

SJW Group’s asset retirement obligation is recorded as a liability included in other non-current liabilities. It reflects principally the retirement costs of wells and other anticipated clean-up costs, which by law, must be remediated upon retirement. Retirement costs have historically been recovered through rates at the time of retirement. As a result, a regulatory asset is also recorded.

The first category is recognized in accordance with ASC Topic 606- “Revenue from Contracts with Customers” and represents metered revenue of Water Utility Services which includes billings to customers based on meter readings plus an estimate of water used between the customers’ last meter reading and the end of the accounting period. SJW Group satisfies its performance obligation upon delivery of water to the customer at which time the customer consumes the benefits provided by the company. The customer is typically billed on a quarterly or bi-monthly basis after water delivery has occurred. The customer is charged both a service charge which is based upon meter size and covers a portion of the fixed costs of furnishing water to the customer and a consumption charge based on actual water usage. Unbilled revenue from the last meter reading date to the end of the accounting period is estimated based on the most recent usage patterns, production records and the effective tariff rates. As the company has the right to bill for services that it has provided, SJW Group estimates the dollar value of deliveries during the unbilled period and recognizes the associated revenue. Actual results could differ from those estimates, which may result in an adjustment to revenue when billed in a subsequent period.

The second category is recognized in accordance with ASC Topic 980-605-25, “Alternative Revenue Programs”. Under Programs established by the CPUC and PURA, allowing for automatic adjustment of future rates, the company recognizes revenue when it is objectively determinable, probable of recovery and expected to be collected within 24 months of the year-end in which the revenue is recognized. A reserve, based on an estimate of actual usage over the recovery period, is recorded for amounts SJW Group estimates will not be collected within the 24-month period. SJW Group’s alternative revenue programs include SJWC’s WCMA and CTWS’s WRA.

•The WCMA allowed SJWC to track lost revenue, net of related water costs, associated with reduced sales due to water conservation and associated calls for water use reductions. SJWC recorded the lost revenue captured in the WCMA balancing accounts. In December 2019, CPUC denied SJWC’s request to recover the 2018 WCMA balance. As a result of the decision, during the year ended December 31, 2019, SJWC wrote off a total balance of $9,386 related to 2018 lost revenue and $639 related to 2019 lost revenue that was recorded in the 2018 and 2019 WCMA accounts, respectively.

•The WRA allows Connecticut Water to mitigate risk associated with changes in demand. The WRA is used to reconcile actual water demands with the demands projected in the most recent general rate case and allows companies to implement a surcharge or surcredit as necessary to recover the revenues approved in the general rate case. The WRA allows the company to defer, as a regulatory asset or liability, the amount by which actual revenues deviate from the revenues allowed in the most recent general rate proceedings.

The third category represents the impact of other balancing and memorandum accounts and other regulatory mechanisms that are accounted for under FASB ASC Topic 980 - “Regulated Operations”. Balancing and memorandum accounts are recognized by SJWC when it is probable that future recovery of previously incurred costs or future refunds that are to be credited to customers will occur through the ratemaking process.

The fourth category, rental income, represents lease rental income. Tenants pay monthly in accordance with lease agreements and SJW Group recognizes the income ratably over the lease term as this is the most representative of the pattern in which the benefit is expected to be derived from SJW Group’s underlying asset.

The compensation cost for service-based restricted stock awards are charged to income on a straight-line basis over the requisite service period, which is the vesting period. For performance-based stock awards, compensation expense is charged to income on a straight-line basis over the requisite service period based on expected attainment of performance targets. Changes in the estimates of the expected attainment of performance targets will result in a change in the number of shares that are expected to vest which may cause a cumulative catch up for the amount of share-based compensation expense during each reporting period in which such estimates are altered. Forfeitures are accounted for as they occur.

Basic earnings per share is calculated using income available to common stockholders, divided by the weighted average number of shares outstanding during the year. Diluted earnings per share is calculated using income available to common stockholders divided by the weighted average number of shares of common stock including both shares outstanding and shares potentially issuable in connection with deferred restricted common stock awards under SJW Group’s Long-Term Incentive Plan and shares potentially issuable under the Employee Stock Purchase Plans. Restricted common stock units of 22,396, 27,082 and 5,551 as of December 31, 2020, 2019 and 2018, respectively, were excluded from the dilutive earnings per share calculation as their effect would have been anti-dilutive.
