SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Summary of Significant Accounting Policies

The accompanying consolidated financial statements 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. 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 principal subsidiary, 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 91% of SJWC’s revenues are derived from the sale of water to residential and business customers.

Connecticut Water Service, Inc. (“CTWS”), headquartered in Connecticut, is a holding company for water utilities companies providing water service to approximately 137,000 connections that serve a population of approximately 480,000 people in 80 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, “SJW Group and CTWS Merger”). The subsidiaries held by CTWS that provide utility water services are The Connecticut Water Company (“Connecticut Water”), The Heritage Village Water Company (“HVWC”), The Avon Water Company (“Avon 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.

SJWTX, Inc., a wholly owned subsidiary of SJW Group, 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 54,000 people. CLWSC’s service area comprises more than 246 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, an undeveloped real estate property, and a warehouse property in the state of Tennessee. In September 1999, SJW Land Company contributed real property for a 70% limited partnership interest in 444 West Santa Clara Street, L.P. A commercial building was constructed on the partnership property and was leased to an unrelated international real estate firm under a long-term lease. 444 West Santa Clara Street, L.P. was 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. The consolidated financial statements of SJW Group at December 31, 2019 and 2018 include the operating results of 444 West Santa Clara Street, L.P. Intercompany balances and transactions have been eliminated. In 2017, the commercial building owned by the partnership was sold. 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”).

Texas Water Alliance Limited (“TWA”), formerly a wholly owned subsidiary of SJW Group, was undertaking activities that were necessary to develop a water supply project in Texas. On February 22, 2016, SJW Group entered into a Purchase and Sale Agreement with the Guadalupe-Blanco River Authority (“GBRA”) pursuant to which SJW Group agreed to sell all of its equity interests in TWA to GBRA for $31,000 in cash. The sales transaction closed on November 16, 2017. As provided in the sale agreement, GBRA held back $3,000 (“Holdback Amount“) from the payment of the purchase price at the closing, which amount will be paid to SJW Group on June 30, 2021, subject to reduction under certain conditions. The transaction resulted in a pre-tax gain on sale of utility property of $12,501, excluding the Holdback Amount.

Recently Adopted Accounting Principles

In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02, “Leases (Topic 842),” as amended, which supersedes the lease requirements in “Leases (Topic 840).” This ASU generally requires lessees to recognize operating and financing lease liabilities and corresponding right-of-use assets on the Consolidated Balance Sheets and to provide enhanced disclosures surrounding the amount, timing and uncertainty of cash flows arising from leasing arrangements. ASU 2016-02 also makes some changes to lessor accounting and aligns with the new

revenue recognition guidance. SJW Group adopted the new standard effective January 1, 2019, on a modified retrospective basis and did not restate comparative periods. SJW Group also elected the package of practical expedients permitted under the transition guidance and combined lease and non-lease components. In addition, SJW Group kept leases with an initial term of 12 months or less off the Consolidated Balance Sheets and recognized the associated lease payments in the Consolidated Statements of Comprehensive Income on a straight-line basis over the lease term. The adoption of this standard did not have a material impact on SJW Group’s consolidated financial statements.

Use of Estimates

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.

Utility Plant

The cost of additions, replacements and betterments to utility plant is capitalized. The amount of interest capitalized in 2019, 2018 and 2017 was $4,323, $2,856 and $2,807, respectively. Construction in progress was $112,232 and $68,765 at December 31, 2019 and 2018, respectively.

The major components of depreciable plant and equipment as of December 31, 2019 and 2018 are as follows:

	2019		2018
Equipment	$	521,183	335,358
Transmission and distribution	2,207,051		1,375,821
Office buildings and other structures	260,220		121,872
Total depreciable plant and equipment	$	2,988,454	1,833,051

Depreciation is computed using the straight-line method over the estimated remaining service lives of groups of assets, ranging from 5 to 75 years. The estimated service lives of depreciable plant and equipment are as follows:

	Useful Lives
Equipment	5 to 35 years
Transmission and distribution plant	35 to 75 years
Office buildings and other structures	7 to 50 years

For the years 2019, 2018 and 2017, depreciation expense as a percent of the beginning of the year balance of depreciable plant was approximately 3.8%, 3.6% and 3.6%, respectively. A portion of depreciation expense was allocated to administrative and general expense. For the years 2019, 2018 and 2017, the amounts allocated to administrative and general expense were $2,869, $2,306 and $2,209, respectively. Depreciation expense for utility plant for the years ended December 31, 2019, 2018 and 2017 was $63,785, $53,031 and $46,456, respectively. The cost of utility plant retired, including retirement costs (less salvage), is charged to accumulated depreciation and no gain or loss is recognized.

Utility Plant Intangible Assets

All intangible assets are recorded at cost and are amortized using the straight-line method over the estimated useful life of the asset, ranging from 5 to 70 years (see Note 6, “Utility Plant Intangible Assets”).

Real Estate Investments

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 and not separately disclosed on the balance sheet based on the immateriality of the amount. Nonutility property is property that is neither used nor useful in providing water utility services to customers and is excluded from the 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. There is no depreciation associated with nonutility property as it is all land.

The major components of real estate investments as of December 31, 2019 and 2018 are as follows:

	2019		2018
Land	$	14,168	13,262
Buildings and improvements	43,531		43,074
Total real estate investment	$	57,699	56,336

Depreciation on buildings and improvements for real estate investments is computed using the straight-line method over the estimated useful lives of the assets, ranging from 7 to 39 years.

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 second 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 6, 2017, 444 West Santa Clara Street, L.P. sold all of its interests in the commercial building and land the partnership owned and operated for $11,000. 444 West Santa Clara Street, L.P. recognized a pre-tax gain on sale of real estate investments of $6,323, after selling expenses of $1,157. SJW Land Company holds a 70% limited interest in 444 West Santa Clara Street, L.P. SJW Land Company and the noncontrolling interest recognized a pre-tax gain on sale of real estate investments of $4,427 and $1,896, respectively, on the transaction. In connection with this sale, the partnership was required to deposit $750 into an escrow account for estimated repairs to the creek next to the land the partnership sold. On April 22, 2019, all creek repairs were completed and a reimbursement of $745 was provided to the 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. In addition, SJW Land Company sold undeveloped land located in San Jose, California for $1,350 on April 6, 2017. SJW Land Company recognized a pre-tax gain on sale of real estate investments of $580 on the transaction, after selling expenses of $14.

Real estate investments include $56,839 and $56,090 as of December 31, 2019 and 2018, 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, 2019:

Year ending December 31:	Rental Revenue
2020	$	4,520
2021	3,208
2022	2,527
2023	2,564
2024	2,645
Thereafter	10,544

Business Combinations

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 uses our best estimates and assumptions to accurately value assets acquired and liabilities assumed at the acquisition date, our estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, we record 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 are 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 or may acquire in the future 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. As of December 31, 2019, management estimated the preliminary fair values of net tangible and intangible assets acquired, and the excess of the consideration transferred over the aggregate of such fair values was recorded as goodwill. The preliminary value of the acquired deferred tax assets and deferred tax liabilities are based on a preliminary analysis, and our estimates and assumptions are subject to change within the measurement period (up to one year from the acquisition date). In addition, management is still gathering information necessary to complete the recognition and measurement of the opening balance sheet (see Note 12, “SJW Group and CTWS Merger”).

Impairment of Long-Lived Assets and Goodwill

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, real estate investments, intangible assets, and regulatory assets. In addition, the company tests unamortized intangible assets, which primarily relate to water rights, at least annually or more frequently if events or changes in circumstances indicate that the asset may be impaired. 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 2019, 2018 or 2017.

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 and must be allocated at the reporting unit level, which is defined as an operating segment or one level below, and tested for impairment at least annually, 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 value. SJW Group’s goodwill is primarily associated with the recent merger with CTWS on October 9, 2019. As of December 31, 2019, SJW Group performed a qualitative assessment and found no indicators of impairment and therefore did not perform the quantitative impairment test.

Cash and Cash Equivalents, and Restricted Fund

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 issuance to Maine Water of $5,000 on December 19, 2019 for construction of a new water treatment plant. Proceeds are held by a trustee for the bond and as conditions are met, funds are released. On February 3, 2020, the trustee released proceeds of $4,114 from the bond.

Financial Instruments and Investments

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, 2019, the value of the company owned life insurance was $7,086 of which $3,829 was related to assets to fund CTWS’ supplemental retirement plan agreements. See discussion on pension plans in Note 9, “Benefit Plans”.

SJW Group’s had an investment in California Water Service Group which was accounted for under FASB ASC Topic 320—“Investment—Debt and Equity Securities,” as an available-for-sale marketable security. The investment was recorded on the Consolidated Balance Sheet at its quoted market price with the change in unrealized gain or loss reported, net of tax, as a

component of other expense (income) with the adoption of ASU 2016-01 on January 1, 2018. Prior to adoption, the changes in unrealized gain or loss, net of tax, were reported as a component of other comprehensive income.

During the year ended December 31, 2018, SJW Group sold its remaining 100,000 shares of California Water Service Group for $4,112 before fees of $9. SJW Group recognized a gain on the sale of the stock of approximately $104 and tax expense of approximately $29 for a net gain of $75.

Regulatory Rate Filings

California Regulatory Affairs

SJWC’s rates, service and other matters affecting its business are subject to regulation by the CPUC.

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.

Cost of capital adjustments are rate adjustments resulting from the CPUC’s usual tri-annual establishment of a reasonable rate of return for SJWC’s capital investments.

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 such as the memorandum account for the Tax Cuts and Jobs Act (H.R. 1) (the “Tax Act”). The purpose of a balancing and memorandum account is to track the under-collection or over-collection associated with such expense changes and activities.

On January 4, 2018, SJWC filed General Rate Case Application No. 18-01-004 (“GRC”) with the CPUC requesting authority for an increase of revenue of $34,288, or 9.76%, in 2019, $14,232, or 3.7%, in 2020 and $20,582, or 5.17%, in 2021. Among other things, the application also included requests to recover $20,725 from balancing and memorandum accounts, the establishment of a Water Revenue Adjustment Mechanism and Sales Reconciliation Mechanism (“WRAM/SRM”), and a shift to greater revenue collection in the service charge. On June 28, 2018, the CPUC issued an order in the case identifying the issues to be considered, including whether the proposed merger between SJW Group and CTWS will have any ratemaking impact on the customers of SJWC (see discussion on the merger with CTWS at Note 12). This consideration was subsequently removed from the GRC to be considered in an Order Instituting Investigation (“OII”) on the proposed merger issued on July 20, 2018, see below for further discussion. On August 10, 2018, SJWC and the Office of Ratepayer Advocates filed a joint motion for partial settlement (“Settlement”) of the GRC with the CPUC, resolving all issues in the GRC with the exception of authorization of a WRAM/SRM and the recovery of the balance in the Hydro Generation Research, Development and Demonstration Memorandum Account, such issues being subsequently contested in legal briefs. The Settlement also lowered authorized sales to a level that aligns more closely with current actual consumption.  In addition, it allowed for a shift in cost recovery allowing 40% of total revenue to be collected through the fixed charge. On October 16, 2018, the CPUC issued a Proposed Decision adopting the Settlement in part, without any impact on the proposed revenue requirement outlined in the Settlement, and delaying ruling on the contested issues in order to allow the Settlement rates to become effective January 1, 2019. On December 4, 2018, the CPUC issued Decision 18-11-025 authorizing new rates for 2019. Accordingly, SJWC filed Advice Letter No. 528/528A on December 7, 2018, requesting authorization to increase revenue requirement by $16,378 or 4.55% in 2019 and to implement surcharges to recover $27,045 of under-collections from memorandum and balancing accounts. This was approved on December 28, 2018, and new rates became effective January 1, 2019.

On July 20, 2018, the CPUC issued an Order Instituting Investigation (“OII”) No. 18-07-007 concerning SJW Group’s then proposed merger with CTWS. A Scoping Memorandum was issued on September 7, 2018, which identified the issues to be considered in the proceeding as to whether the proposed merger is subject to CPUC approval and to evaluate the merger’s likely impacts within California. On September 14, 2018, SJW Group and SJWC submitted joint comments in response to the issues identified in accordance with the Scoping Memorandum’s adopted schedule, and reply comments were submitted on October 19, 2018. A Public Participation Hearing was held on January 31, 2019. On March 4, 2019, the CPUC suspended this proceeding due to SJW Group’s announcement of its intention to file a new merger approval application with the Connecticut Public Utilities Regulatory Authority (“PURA”). On April 3, 2019, SJW Group and CTWS jointly filed a new merger

application with PURA. After securing the required approvals from both PURA and the MPUC, SJW Group announced the close of the merger on October 9, 2019, and notified the CPUC accordingly.

In January 2017, a SJWC customer inquired about the company’s billing practice as it related to the proration of service charges in billing cycles where a rate change occurred. On June 22, 2017, SJWC was served with Complaint 17-06-009 regarding its billing practice for service charge rate changes. The billing issue was made a part of SJWC’s GRC proceeding and a settlement agreement was reached with the Office of Ratepayer Advocates (now the Public Advocates Office) on May 23, 2018, limiting the duration from which to calculate customer refunds from June 1, 2011, through December 31, 2016. Accordingly, SJWC provided an additional reserve to cover the remaining period covered by the settlement. In accordance with Decision 18-11-025 for the GRC, SJWC filed Advice Letter No. 530 proposing total refunds of $2,020 for the period from June 1, 2011 through December 31, 2016. This advice letter became effective February 8, 2019, and refunds were completed by mid-May 2019. On April 22, 2019, the CPUC dismissed Complaint 17-07-009 citing the relief provided in Advice Letter No. 530 and the current OII on this matter (see below for further discussion). The Complainant filed an appeal with the CPUC to dispute the dismissal. This appeal was rejected and the Complaint was dismissed via CPUC Decision No. 19-09-040 on September 24, 2019.

On September 14, 2018, the CPUC issued OII No. 18-09-003 to which SJWC was named as Respondent. The OII will determine whether the company unlawfully overcharged customers over a 30-year period by failing to pro-rate service charges when increases occurred during a billing period, and whether the company double-billed service charges during one billing period when allegedly switching from billing such charges in advance to billing in arrears.  The OII resulted from a report by the CPUC’s Consumer Protection and Enforcement Division (“CPED”), dated August 16, 2018, recommending an investigation into SJWC’s billing practice.  CPED calculated a refund obligation of approximately $2,061 for the years 2014 to 2016 that had been the subject of SJWC’s Advice Letter No. 510.  CPED calculated a further refund obligation of approximately $1,990 for the years 1987 to 2013.  CPED also asserted that the company double-billed its customers during a billing period when it allegedly converted from billing in advance to billing in arrears, assumed that such double-billing occurred in January 2011, and calculated a refund obligation of approximately $4,935.  The OII notes these estimates and identifies the proper refund amount as an issue in the proceeding.  The OII also identifies the CPUC’s authority to consider imposing penalties on SJWC in amounts ranging from five hundred dollars to fifty thousand dollars per offense, per day. On July 24, 2019, SJWC and CPED jointly filed a motion for CPUC approval of a Settlement Agreement (“Agreement”) over SJWC’s past customer billing practices. The Agreement requires the company to pay approximately $2,100 in customer credits, consisting of $1,757 for refunds during the period from 1987 to 2011 and an additional $350 in customer credits to low income water customers, and invest $5,000 in utility plant that is not allowed an investment return or rate recovery. SJWC has recorded the $2,100 customer credit expense as an offset to revenues in the accompanying December 31, 2019, Consolidated Statements of Comprehensive Income. The $5,000 commitment to invest in utility plant will be recognized as plant in service on the company’s financial statements once invested. The Agreement is subject to final approval by the CPUC. A CPUC Presiding Officer’s Decision approved the Agreement in December 2019, but an appeal was filed in January 2020 by a group of SJWC customers. A final CPUC decision approving the Settlement and dismissing the appeal was approved on February 27, 2020.

On February 28, 2019, SJWC filed Advice Letter No. 531 with the CPUC requesting to adjust the Utilities Reimbursement Account User Fees as directed by CPUC Resolution M-4839. The reimbursement fee was reduced from 1.4% to 1.23%. This request was approved and the new fee became effective on April 1, 2019.

On March 29, 2019, SJWC filed Advice Letter No. 532 with the CPUC requesting authorization to recover its 2018 WCMA balance for the period of January 1, 2018, through December 31, 2018. On December 19, 2019, the CPUC denied the recovery via Resolution W-5210 citing the elimination of mandatory conservation requirements. SJWC recorded a reduction of balancing and memorandum accounts of $9,386 with an offset to revenues for the 2018 WCMA and reversed revenues of $639 recorded in the 2019 WCMA during the period ended December 31, 2019.

On June 19, 2019, the CPUC issued its final decision resolving the remaining issues in SJWC’s GRC. Decision 19-06-010 denied the establishment of a WRAM/SRM and authorized the recovery of the Hydro Generation Research, Development and Demonstration Memorandum Account balance of $1,243. SJWC filed Advice Letter No. 534 on August 1, 2019, to recover this amount via a surcharge over a three-year period. The CPUC rejected the advice letter on October 10, 2019, citing an error and recommended a correction and a new filing for recovery. SJWC has made a filing to correct the record and is awaiting the CPUC’s decision. A new advice letter for recovery is anticipated to be filed in the first quarter of 2020 pending the decision.

On August 30, 2019, SJWC filed Advice Letter No. 535 with the CPUC requesting authorization to increase the total 2019 authorized revenue requirements by $0.7 million or 0.17% for plant additions related to the Montevina Water Treatment Plant Upgrade Project in 2018. This advice letter became effective on September 29, 2019.

SJWC filed Advice Letter No. 537 with the CPUC requesting authorization to refund the balance in its 2018 Tax Accounting Memorandum Account as required by the GRC decision on October 18, 2019.  On December 3, 2019, Advice Letter 537-A was filed to refund the balance via a one-time surcredit. For a typical residential customer with a 3/4-inch meter, the one-time

refund will be $20.84.  This advice letter was approved effective January 1, 2020, and refunds to customers began on January 27, 2020.

SJWC filed Advice Letter No. 541 on November 20, 2019, with the CPUC requesting authorization to increase its revenue requirement by $8,600 or 2.28% in 2020 for the first escalation year authorized in our 2018 General Rate Case Decision 18-011-025 which established rates for 2019, 2020, and 2021. This advice letter was approved on December 26, 2019, and new rates became effective January 1, 2020.

On December 6, 2019, SJWC filed Application No. 19-12-002 with the CPUC requesting approval for cost recovery to deploy Advanced Metering Infrastructure throughout its service area.  The application seeks revenue increases of $2.3 million or 0.61% in 2021, $4.0 million or 1.04% in 2022, and $2.5 million or 0.65% in 2023, and $0.3 million or 0.09% in 2024 based on current rates in effect.  A decision from the CPUC is anticipated in the fourth quarter of 2020.

On January 22, 2020, SJWC, along with California-American Water Company, California Water Service Company, and Golden State Water Company, 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 is conditioned on no changes to the current Water Cost of Capital Mechanism in place during the one-year deferment. A CPUC decision is expected in the first quarter of 2020.

Connecticut Regulatory Affairs

Connecticut Water, HVWC and Avon Water’s rates, service and other matters affecting its business are subject to regulation by the Public Utilities Regulatory Authority of Connecticut (“PURA”). The Connecticut regulated operations seek rate relief as necessary to enable it to achieve an authorized rate of return.

PURA generally establishes rates in Connecticut on a company-wide basis and 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 HVWC 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. Avon Water does not currently use the WRA mechanism.

As of December 31, 2019, WICA surcharges for Connecticut Water and Avon Water were 3.24% and 9.31%, respectively. HVWC does not currently 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 filed its annual WICA reconciliation which called for a 0.09% reduction of the WICA surcharge. If approved as filed, Connecticut Water will begin to charge customers a cumulative WICA surcharge of 5.75% on April 1, 2020.

Connecticut Water and HVWC’s allowed revenues, as approved by PURA during each company’s last general rate case and including subsequently approved WICA surcharges for Connecticut Water, were approximately $18,588 for the period from October 9, 2019, through December 31, 2019. Through the normal billing, for the period from October 9, 2019 through December 31, 2019, revenues received from water and wastewater customers would have been approximately $20,428. As a result of the utilization of the WRA mechanism, Connecticut Water and HVWC recorded an approximate $1,840 reduction in revenues for the period from October 9, 2019 through December 31, 2019.

Texas Regulatory Affairs

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.

As required, CLWSC submitted on January 28, 2019, its Water Pass-Through Charge (“WPC”) true-up report for the Canyon Lake area systems 2018 purchased water costs to the PUCT reflecting a change from $1.13 to $1.05 per thousand gallons. The WPC is the annual filing to change that component of CLWSC’s water rates for the changes in purchased water costs since the

last annual true-up report. This change for 2019 became effective on water bills being prepared as of February 1, 2019. Two WPC true-up reports were filed to report the year 2019 costs. The changes in the purchased water costs for the Deer Creek Ranch water system resulted in a decrease in the usage charge from $2.19 to $2.02 per thousand gallons, and an increase in the monthly base charge of $3.04 per residential account. These Deer Creek Ranch rate changes became effective October 1, 2019. The 2019 WPC true-up report for the water systems located in the Canyon Lake area resulted in a reduction of the WPC usage rate from $1.05 to $0.95 per thousand gallons which became effective on February 1, 2020.

Maine Regulatory Affairs

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 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 December 20, 2019, Maine Water filed a general a rate increase for their Skowhegan Division seeking approximately $221, or 14.7%, in additional revenue with the MPUC. A final decision from the MPUC is expected in the second quarter of 2020. 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 are effective March 1, 2020.

Balancing and Memorandum Accounts

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.

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. In addition, in the case of special revenue programs such as the Water Conservation Memorandum Account (“WCMA”) and WRA, SJWC and CTWS follow the requirements of ASC Topic 980-605-25—“Alternative Revenue Programs” in determining revenue recognition, including the requirement that such revenues will be collected within 24 months of the year-end in which the revenue is recorded. A reserve is recorded for amounts SJW Group estimates will not be collected within the 24-month period. This reserve is based on an estimate of actual usage over the recovery period, offset by applicable drought surcharges. In assessing the probability criteria for balancing and memorandum accounts between general rate cases, SJWC considers evidence that may exist prior to CPUC authorization that would satisfy ASC Topic 980 subtopic 340-25 recognition criteria. Such evidence may include regulatory rules and decisions, past practices, and other facts and circumstances that would indicate that recovery or refund is probable. When such evidence provides sufficient support, the balances are recorded in SJW Group’s consolidated financial statements.

On December 19, 2019, the CPUC denied the recovery of the 2018 WCMA in Advice Letter No. 532 and no longer approved the tracking of WCMA balances. Due to the decision, SJWC believes it no longer meets the probability criteria under ASC Topic 980-605-25 for the 2018 WCMA and has recognized a reduction to regulatory assets of $9,386 for the year ended December 31, 2019. SJWC had previously recognized regulatory assets of $9,386 due to lost revenues accumulated in the 2018 WCMA account for the year ended December 31, 2018. As of December 31, 2018, there was no reserve recorded to offset the 2018 WCMA.

As a result of the current status of the CPUC filing for the 2018 WCMA above, SJW Group also eliminated the regulatory asset balance for its 2019 WCMA as of December 31, 2019. As of December 31, 2019, $639 in lost revenues had accumulated in the 2019 WCMA.

SJWC recognized regulatory assets of $1,182 due to lost revenues accumulated in the 2017 WCMA account which represented the relief of the prior year reserve of $1,169 and interest earned on the balance during the year ended December 31, 2018. The prior year reserve represented the estimated amount that may not be collected within the 24-month period defined in the guidance. These amounts have been recorded in the 2017 WCMA balance shown in the table below for the year ended December 31, 2018. As of December 31, 2018, there was no reserve balance netted from the balance below.

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 the tax memorandum account began on January 27, 2020.

In 2018, SJWC re-evaluated the accounting for cost-recovery balancing and memorandum accounts under the new revenue recognition guidance, ASU 2014-09, “Revenue from Contracts with Customers.” Prior to adoption, SJWC recorded cost-recovery accounts as a component of revenue. Upon adoption of ASU 2014-09, SJWC began recording such balances as capitalized costs until recovery is approved by the CPUC. The change is reflected in the cost-recovery balancing and memorandum accounts as shown in the table below.

SJWC met the recognition requirements for certain of its balancing and memorandum accounts and certain amounts subject to balancing and memorandum accounts and recorded revenue and regulatory assets as follows:

	For the year ended December 31, 2019

As of December 31, 2019, the total balance in SJWC’s balancing and memorandum accounts combined, including interest, that has not been recorded into the financial statements was a net under-collection of $1,428.

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, 2019, SJWC collected $25,108 in surcharges for the approved recovery.

All balancing accounts and memorandum-type accounts not included for recovery or refund in the current general rate case will be reviewed by the CPUC in SJWC’s next general rate case or at the time an individual account reaches a threshold of 2% of authorized revenue, whichever occurs first.

Regulatory Assets and Liabilities

Generally accepted accounting principles for water utilities include the recognition of regulatory assets and liabilities as permitted by ASC Topic 980. In accordance with ASC Topic 980, Water Utility Services, to the extent applicable, records deferred costs and credits on the balance sheet as regulatory assets and liabilities when it is probable that these costs and credits will be recognized in the ratemaking process in a period different from when the costs and credits are incurred. Accounting for such costs and credits is based on management’s judgment and prior historical ratemaking practices, and it occurs when management determines that it is probable that these costs and credits will be recognized in the future revenue of Water Utility Services through the ratemaking process. The regulatory assets and liabilities recorded by Water Utility Services primarily relate to the recognition of deferred income taxes for ratemaking versus tax accounting purposes, balancing and memorandum

accounts, debt premiums related to business combinations, postretirement pension benefits, medical costs, accrued benefits for vacation and asset retirement obligations that have not yet been passed through in rates. For Connecticut and Maine water utility services, regulatory assets and liabilities also include deferred revenues associated with the WRA regulatory mechanism (see discussion in Regulatory and Rates Regulation section above). The company adjusts the related asset and liabilities for these items through its regulatory asset and liability accounts at year-end, except for certain postretirement benefit costs and balancing and memorandum accounts which are adjusted monthly. The company expects to recover regulatory assets related to plant depreciation income tax temporary differences over the average lives of the plant assets of between 5 to 75 years.

Rate-regulated enterprises are required to charge a regulatory asset to earnings if and when that asset no longer meets the criteria for being recorded as a regulatory asset. 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.

Regulatory assets and liabilities are comprised of the following as of December 31:

	2019		2018
Regulatory assets:
Income tax temporary differences, net	$	2,433	—
Postretirement pensions and other medical benefits	73,525		66,233
Business combinations debt premium, net	25,020		—
Balancing and memorandum accounts, net	5,283		34,413
WRA	9,108		—
Other, net	5,048		2,979
Total regulatory assets, net in Consolidated Balance Sheets	120,417		103,625
Less: current regulatory asset, net	6,472		26,910
Total regulatory assets, net, less current portion	$	113,945	76,715
Regulatory liability:
Income tax temporary differences, net	$	—	59,149
Total regulatory liability in Consolidated Balance Sheets	$	—	59,149

Income Taxes

On December 22, 2017, the Tax Act was signed into law. Among other things, the Tax Act lowers the corporate tax rate to 21% from the maximum rate of 35%, effective for tax years including or commencing January 1, 2018. See also Note 5, “Income Taxes”.

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.

To the extent permitted by the regulators, investment tax credits resulting from utility plant additions are deferred and amortized over the estimated useful lives of the related property.

Advances for Construction and Contributions in Aid of Construction

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. Estimated refunds for the next five years and thereafter are shown below:

	Estimated Refunds
2020	$	2,890
2021	2,890
2022	2,890
2023	2,878
2024	2,799
Thereafter	49,631

As of December 31, 2019, advances for construction was $112,339 of which $21,463 was related to non-refundable advances for construction and $26,898 was related to advances which are refunded based on service connections made.

Contributions in aid of construction represent funds received from developers that are not refundable under applicable regulations. Depreciation applicable to utility plant constructed with these contributions is charged to contributions in aid of construction.

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 life of the related asset for contributions. Receipts subsequent to June 12, 1996 are generally exempt from federal taxable income, unless specifically prescribed under treasury regulations, including CTWS.

Advances and contributions received subsequent to 1991 and prior to 1997 are included in state taxable income, except for CTWS.

Asset Retirement Obligation

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, the liability is offset by a regulatory asset.

As of December 31, 2019 and 2018, the asset retirement obligation is as follows:

	2019			2018
Retirement obligation	$	4,803		4,803
Discount rate	6		%	6	%
Regulatory asset, present value, recorded as a liability	$	942		942

Revenue

SJW Group recognizes revenue in accordance with ASC Topic 606 - “Revenue from Contracts with Customers.” In accordance with Topic 606, management has determined that the company has principally four categories of revenues. The first category, revenue from contracts with customers, 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, rental income, represents lease rental income from SJW Land Company and Chester Realty, Inc. tenants. The 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 third and fourth revenue categories are other balancing and memorandum accounts and alternative revenue programs. Both are scoped out of Topic 606 and 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. In addition, in the case of special revenue programs, SJWC, Connecticut Water, and HVWC follow the requirements of ASC Topic 980-605-25, “Alternative Revenue Programs” in determining revenue recognition, including the requirement that such revenues will be collected within 24 months of the year-end in which the revenue is recorded. A reserve is recorded for amounts SJW Group estimates will not be collected within the 24-month period. This reserve is based on an estimate of actual usage over the recovery period, offset by applicable drought surcharges. In assessing the probability criteria for balancing and memorandum accounts between general rate cases, SJWC considers evidence that may exist prior to CPUC authorization that would satisfy ASC Topic 980 subtopic 340-25 recognition criteria. Such evidence may include regulatory rules and decisions, past practices, and other facts and circumstances that would indicate that recovery or refund is probable. When such evidence provides sufficient support, the balances are recorded in SJW Group’s financial statements.

To encourage conservation, SJWC received approval from the CPUC to implement a Mandatory Conservation Revenue Adjustment Memorandum Account in 2014. This account was subsequently replaced with a WCMA. 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 regulatory accounts once the revenue recognition requirements of FASB ASC Topic 980 - “Regulated Operations,” subtopic 605-25 were met. In December 2019, CPUC denied SJWC’s request in Advice Letter No. 532 to recover the 2018 balances of WCMA and was ordered to remove the WCMA accounts from the preliminary statement book. 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. For further discussion, please see “Balancing and Memorandum Accounts” in Note 1.

The major streams of revenue for SJW Group are as follows:

	2019			2018		2017
Revenue from contracts with customers	$	447,720		389,302		381,777
Alternative revenue programs, net	(18,232		)	10,456		12,584
Other balancing and memorandum accounts revenue, net (1)	(14,403		)	(7,541	)	(10,838	)
Rental income	5,397			5,482		5,702
	$	420,482		397,699		389,225

___________________________________

(1) For year ended December 31, 2019 and 2018, $962 and $2,643, respectively, of amounts related to cost-recovery balancing accounts which upon adoption of Topic 606 are recorded as capitalized costs rather than revenue until recovery is approved by the CPUC. Prior to adoption of Topic 606, these amounts were recorded as revenue. For further discussion, please see “Balancing and Memorandum Accounts” above.

Revenue also includes a surcharge collected from regulated customers that is paid to the CPUC. This surcharge is recorded both in operating revenues and administrative and general expenses. For the years ended December 31, 2019, 2018 and 2017, the surcharge was $4,955, $5,013 and $5,017, respectively.

Share-Based Compensation

SJW Group calculates the fair value of service-based and performance-based restricted stock awards based on the grant date fair market value of the company’s stock price reduced by the present value of the dividends expected to be declared on outstanding shares.

SJW Group utilizes the Monte Carlo valuation model, which requires the use of subjective assumptions, to compute the fair value of market-vesting restricted stock units.

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.

Maintenance Expense

Planned major maintenance projects are charged to expense as incurred.

Earnings per Share

Basic earnings per share is calculated using income available to common stockholders, divided by the weighted average number of shares outstanding during the year. The two-class method in computing basic earnings per share is not used because the number of participating securities as defined in FASB ASC Topic 260—“Earnings Per Share” is not significant. The two-class method is an earnings allocation formula that determines earnings per share for each class of common stock and participating security. 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 27,082, 5,551 and 4,474 as of December 31, 2019, 2018 and 2017, respectively, were excluded from the dilutive earnings per share calculation as their effect would have been anti-dilutive.
