NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1. Basis of Preparation of Financials

The condensed consolidated financial statements included herein have been prepared by Connecticut Water Service, Inc. (“CTWS” or the “Company”) and its wholly-owned subsidiaries, pursuant to the rules and regulations of the Securities and Exchange Commission and reflect all adjustments that are of a normal recurring nature which are, in the opinion of management, necessary to a fair statement of the results for interim periods.  Certain information and footnote disclosures have been omitted pursuant to such rules and regulations, although the Company believes that the disclosures are adequate to make the information presented not misleading.  The Company’s primary operating subsidiaries are: The Connecticut Water Company (“Connecticut Water”), The Heritage Village Water Company (“HVWC”) and The Avon Water Company (“Avon Water”) in the State of Connecticut and The Maine Water Company (“Maine Water”) in the State of Maine. The Condensed Consolidated Balance Sheet at December 31, 2017 has been derived from the audited financial statements at that date but does not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements.  It is suggested that these condensed consolidated financial statements be read in conjunction with the financial statements and the notes thereto included in the Company’s latest Annual Report on Form 10-K for the fiscal year ended December 31, 2017 (the “10-K”) and as updated in the Company’s Quarterly Report on Form 10-Q for the period ended March 31, 2018.

The results for interim periods are not necessarily indicative of results to be expected for the year since the consolidated earnings are subject to seasonal factors.  Effective February 27, 2017 and July 1, 2017, the Company acquired HVWC and Avon Water, respectively, discussed further in Note 12 below.  As a result, the Company’s Condensed Consolidated Statements of Net Income, Condensed Consolidated Statements of Comprehensive Income, Condensed Consolidated Statements of Retained Earnings and Condensed Consolidated Statements of Cash Flows for the three and six months endedJune 30, 2017 do not include Avon Water, however, they do include the approximate four months of activity related to HVWC after its acquisition on February 27, 2017.  The Condensed Consolidated Statements of Net Income, Condensed Consolidated Statements of Comprehensive Income, Condensed Consolidated Statements Retained Earnings and the Condensed Consolidated Statements of Cash Flows for the three and six months endedJune 30, 2018 include HVWC’s and Avon Water’s results. HVWC’s and Avon Water’s assets and liabilities are included in the Condensed Consolidated Balance Sheet as of June 30, 2018 and December 31, 2017.

As noted in Note 12 below, HVWC serves approximately 4,700 water customers in the Towns of Southbury, Middlebury, and Oxford, Connecticut and approximately 3,000 wastewater customers in the Town of Southbury, Connecticut. The results of the wastewater line of business are included in the Company’s Water Operations segment. Additionally, as noted in Note 12, Avon Water serves approximately 4,800 water customers in the Towns of Avon, Farmington, and Simsbury, Connecticut.

Proposed Merger with SJW Group

On August 5, 2018, the Company entered into a Second Amended and Restated Agreement and Plan of Merger (the “Revised Merger Agreement”) with SJW Group, a Delaware corporation (“SJW”), and Hydro Sub, Inc., a Connecticut corporation and a direct wholly owned subsidiary of SJW (“Merger Sub”), pursuant to which Merger Sub will merge with and into the Company, with the Company surviving the Merger as a wholly owned subsidiary of SJW (the “Merger”). Subject to the terms and conditions of the Revised Merger Agreement, at the effective time of the Merger, each outstanding share of our common stock (other than certain cancelled shares) will be automatically converted into the right to receive an amount in cash equal to $70.00 per share, payable without interest. The Revised Merger Agreement amends and restates in its entirety the Amended and Restated Agreement and Plan of Merger (the “First Amended and Restated Merger Agreement”), dated as of May 30, 2018, by and among the Company, SJW and Merger Sub, which amended and restated in its entirety the Agreement and Plan of Merger (the “Original Merger Agreement”), dated as of March 14, 2018, by and among the Company, SJW and Merger Sub.

The Board of Directors approved, adopted and declared advisable and resolved to recommend to the Company’s shareholders the approval of the Revised Merger Agreement and the Merger following a comprehensive review of the transaction.

The Merger is subject to certain customary closing conditions, including, among other things, approval of the Revised Merger Agreement by the Company’s shareholders and regulatory approvals (including the approval of the Connecticut Public Utilities Regulatory Authority (“PURA”) and the Maine Public Utilities Commission (“MPUC”) and pre-approvals of any license transfers from the Federal Communications Commission). The required waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and the rules and regulations promulgated thereunder (the “HSR Act”), was terminated early on April 27, 2018.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (continued)

On May 4, 2018, Maine Water filed with the MPUC an application for approval of the Merger. On May 7, 2018, the Company and SJW filed with the PURA a joint application for approval of the Merger. Following the start on May 31, 2018 of a 45-day go-shop process permitted by the First Amended and Restated Merger Agreement, the Company and SJW withdrew their joint application on June 19, 2018, and filed a new joint application on July 18, 2018, following the end of the go-shop process.

On July 20, 2018, the California Public Utilities Commission (“CPUC”) formally issued an Order Instituting Investigation (“Order”) providing that the CPUC will investigate whether the Merger is subject to CPUC approval and the Merger’s anticipated impacts within California. The Order states that the CPUC plans to substantially complete its investigation in a manner sufficiently timely to allow the Merger to go forward by the end of 2018, if appropriate.

The Company and SJW expect the closing of the Merger to occur during the first quarter of 2019.

Regulatory Matters

The rates we charge our water and waste water customers in Connecticut and Maine are established under the jurisdiction of and are approved by PURA and the MPUC, respectively. It is our policy to seek rate relief as necessary to enable us to achieve an adequate rate of return. The Regulated Companies’ allowed returns on equity and allowed returns on rate base are as follows:

As of June 30, 2018	Allowed Return on Equity		Allowed Return on Rate Base
Connecticut Water	9.75	%	7.32	%
HVWC (blended water and wastewater rates)	10.10	%	7.19	%
Avon Water	10.00	%	7.79	%
Maine Water	9.50	%	7.96	%

The PURA establishes rates in Connecticut on a company-wide basis while the MPUC approves Maine Water’s rates on a division-by-division basis. Each of Connecticut Water, HVWC, Avon Water and Maine Water are allowed to add surcharges to customers’ bills in order to recover certain costs associated with approved capital projects in between full rate cases, as well as approved surcharges for Water Revenue Adjustments, in Connecticut, as discussed in more detail below. HVWC has not added surcharges to customers’ bills in order to recover certain approved capital projects as of June 30, 2018, however, HVWC, as ordered by PURA, began to utilize Water Revenue Adjustments as of March 31, 2017.

On January 3, 2018, PURA filed a motion to reopen the most recent rate case decisions for the Company’s Connecticut Regulated Companies to determine what, if any, adjustments to rates are appropriate to account for revisions to tax laws, including corporate tax rates, contained in the Tax Cuts and Jobs Act (“Tax Act”). PURA held a hearing on July 30, 2018 for regulated water companies. As discussed below, Connecticut Water has entered into a settlement agreement with the Connecticut Office of Consumer Counsel (“OCC”) that covers treatment of the Tax Act.

On January 11, 2018, the MPUC issued a notice of investigation to determine the impact of the Tax Act on Maine Water. The investigation will allow the MPUC to determine the specific impact of the Tax Act and whether any rate adjustments are warranted. Following discovery, technical conferences were held on April 19, 2018 and July 17, 2018. The current schedule for the investigation anticipates a report by the Hearing Examiner on August 13, 2018. In addition to determining the impact of the Tax Act on the justness and reasonableness of Maine Water’s rates, the MPUC will consider whether to issue an accounting order to establish a regulatory liability which defers for future flow-through to ratepayers the impact of the tax changes.

Maine Water Land Sale

On March 11, 2016, Maine Water entered into a purchase and sale agreement with the Coastal Mountains Land Trust, a Maine nonprofit corporation (the “Land Trust”) pursuant to which Maine Water agreed to sell two conservation easements to the Land Trust on approximately 1,300 acres of land located in the towns of Rockport, Camden and Hope, in Knox County, Maine valued in the aggregate at $3.1 million.  The land had a book value of approximately $600,000 at June 30, 2018 and December 31, 2017 and is included in “Utility Plant” on the Company’s Consolidated Balance Sheets. The easements and purchase prices are as follows:

1.Ragged Mountain Mirror Lake Conservation Easement: $1,875,000; and

2.Grassy Pond conservation Easement: $600,000.

On June 25, 2018, an amendment to the agreement was made to extend closing of the first transaction to September 30, 2018, from June 30, 2018.  This is also expected to extend the second closing into 2020.  Maine Water will make a $250,000 contribution to the Land Trust upon completion of the closing of the first easement sale.  Maine Water also expects to claim a charitable deduction for the $600,000 in excess of the fair market value of the second easement over the $600,000 sale price.

Connecticut Rates

Connecticut Water’s Water Infrastructure Conservation Adjustment (“WICA”) was 9.98% and 8.25% at June 30, 2018 and 2017, respectively. As of June 30, 2018, Avon Water’s WICA surcharge was 7.51%. As of June 30, 2018, HVWC has not filed for a WICA surcharge.

On February 6, 2018, Connecticut Water filed a petition with PURA to reopen Connecticut Water’s 2010 rate case proceeding (previously reopened in 2013) for the limited purpose of approving a Settlement Agreement entered into by Connecticut Water and the OCC (the “Agreement”). The Agreement proposes a change in Connecticut Water’s customer rates effective for bills rendered on and after April 1, 2018 made up of the following two components: (1) the revenue requirements associated with a $36.3 million addition to rate base to reflect necessary upgrades to Connecticut Water’s Rockville Water Treatment Plant; and (2) the folding in to base rates of the Company’s present WICA surcharges. In addition, the Agreement provides that:

1. Upon implementation of new rates under the Agreement, until such time as new rates are adopted in a general rate case, through a temporary modification of the earnings sharing mechanism, Connecticut Water customers will receive one hundred percent of any earnings in excess of levels allowed by law rather than limiting such customer credits to 50% as contemplated by applicable law;

2. Connecticut Water agrees it will not file for a general increase of Connecticut Water’s base rates to be effective before January 1, 2020;

3. The pending proceeding initiated by PURA in Docket No. 09-12-11RE03, Application of The Connecticut Water Company for Amended Rates – Federal Tax Cuts and Jobs Act shall be closed; and

4. Connecticut Water shall continue to make investments in infrastructure replacement consistent with its approved WICA plan. Connecticut Water shall be allowed to continue to pursue recovery of eligible projects through WICA.

The Agreement provides that, if PURA does not fully approve the Agreement in its entirety, it shall be deemed withdrawn.  Accordingly, the Agreement has no operative effect unless and until it is approved by PURA.  No assurance can be given that PURA will approve the Agreement and permit some or all of the terms contained in the Agreement requested by the parties.  PURA has agreed to the request to reopen the rate proceeding.  PURA issued a Proposed Final Decision on July 6, 2018 that rejected the Settlement Agreement, due to the proposed treatment of income tax expense resulting from the Tax Act. The Company and the Office of Consumer Council each filed written exceptions to the draft decision and a hearing was held on a revised settlement agreement submitted from both parties that would include an adjustment to reflect the impacts of the Tax Act but at a lower dollar amount than recommended in the PURA draft decision.  A final decision is anticipated from PURA in August with implementation of new rates to immediately follow.

Since 2013, Connecticut law has authorized a Water Revenue Adjustment (“WRA”) to reconcile actual water revenues with the revenues projected in the last general rate case and allows companies to adjust rates as necessary to recover the revenues approved by PURA in the last 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. Additionally, projects eligible for WICA surcharges were expanded to include energy conservation projects, improvements required to comply with streamflow regulations, and improvements to certain acquired systems.

Connecticut Water’s and HVWC’s allowed revenues for the six months endedJune 30, 2018, as approved by PURA during each company’s most recent general rate case and including subsequently approved WICA surcharges, are approximately $38.7 million. Through normal billing for the six months endedJune 30, 2018, revenue for Connecticut Water and HVWC would have been approximately $35.2 million had the WRA not been implemented. As a result of the implementation of the WRA, Connecticut Water and HVWC recorded $3.5 million in additional revenue for the six months endedJune 30, 2018. Avon Water does not currently use the WRA mechanism. Avon Water does not currently have PURA approval to apply the WRA surcharge to their customers’ bills.

Maine Rates

In Maine, the overall, cumulative Water Infrastructure Charge (“WISC”) for all divisions was 6.8% and 5.7% as of June 30, 2018 and 2017, respectively. The WISC rates for the Biddeford and Saco division were reset to zero with the approval of the general rate increase discussed below.

11

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (continued)

On June 29, 2017, Maine Water filed for a rate increase in its Biddeford and Saco division. The rate request was for an approximate $1.6 million, or 25.1%, increase in revenues. The rate request is designed to recover higher operating expenses, depreciation and property taxes since Biddeford and Saco’s last rate increase in 2015. Maine Water and the Maine Office of the Public Advocate reached an agreement that increases annual revenue by $1.56 million. The agreement was approved by the MPUC on December 5, 2017, with new rates effective December 1, 2017.

A water revenue adjustment mechanism law in Maine became available to regulated water utilities in Maine on October 15, 2015. Maine Water is currently precluded from seeking new rates in the Biddeford and Saco division due to provisions in the settlement agreement with the MPUC. As the stay-out periods for other divisions expire, Maine Water expects to request usage of this mechanism as Maine Water file rate cases for those divisions.

4. Recently Adopted and New Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers,” (“ASU No. 2014-09”) which amended its guidance related to revenue recognition. ASU No. 2014-09 requires an entity to recognize revenue as performance obligations are met, in order to reflect the transfer of promised goods or services to customers in an amount that reflects the consideration the entity is entitled to receive for those goods or services. The following steps are applied in the updated guidance: (1) identify the contract(s) with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when, or as, the entity satisfies a performance obligation. ASU No. 2014-09 became effective for public companies for fiscal years, and interim periods within those years, beginning after December 15, 2016, and could be adopted either retrospectively to each prior reporting period presented or as a cumulative-effect adjustment as of the date of adoption, however early adoption is not permitted. On April 1, 2015, the FASB voted for a one-year deferral of the effective date of ASU No. 2014-09, making ASU No. 2014-09 effective for public companies for fiscal years, and interim periods within those years, beginning after December 15, 2017. The Company engaged in a project to analyze the impact that adoption of this standard would have on our consolidated financial statements, disclosures, and internal controls. The project included identification of the Company’s revenue streams, creation of an inventory of its contracts with customers, evaluation of a representative sample of these contracts with respect to the new guidance and documentation of any required changes in reporting. The Company derives more than 90% of its revenue from regulated delivery of water and wastewater services to its retail customers, which is considered a contract with customers under ASU 2014-09, excluding revenue recognized as WRA. The majority of the remainder of the Company’s revenue is derived from contract operations and unregulated revenues generated from its Linebacker^® program, also considered a contract with customers under ASU 2014-09. The Company determined that revenue generated from the attachment of telecommunications equipment to its facilities through leases with third parties is outside the scope of ASU No. 2014-09. In 2017, the American Institute of Certified Public Accountants (AICPA) power and utility entities revenue recognition task force determined that contributions in aid of construction are not in the scope of ASU No. 2014-09. The Company’s adoption of ASU No. 2014-09 on January 1, 2018 did not result in any change in the measurement and timing of recognition of its revenues. The Company used the modified retrospective approach when implementing ASU No. 2014-09. See Note 5 for more details.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (continued)

In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842)”, (“ASU No. 2016-02”), which will require lessees to recognize the following for all leases at the commencement date of a lease: a) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and b) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Public business entities should apply the amendments in ASU No. 2016-02 for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application is permitted for all public business entities and all nonpublic business entities upon issuance. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Lessees and lessors may not apply a full retrospective transition approach. The Company is currently assessing the impact of this standard on its consolidated financial statements and footnote disclosures, but does not expect that the adoption of this guidance will materially impact our consolidated financial position.

In August 2016, the FASB issued ASU No. 2016-15, “Classification of Certain Cash Receipts and Cash Payments” (“ASU No. 2016-15”). The amendments ASU No. 2016-15 clarify the classification for eight different types of activities, including debt prepayment and extinguishment costs, proceeds from insurance claims and distributions from equity method investees. For public business entities, ASU No. 2016-15 is effective for financial statements issued for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. The Company’s adoption of this guidance did not materially impact our consolidated financial position or cash flows.

In March 2017, the FASB issued ASU 2017-07, "Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost," (“ASU 2017-07”) which amends the requirements related to the income statement presentation of the components of net periodic benefit cost for employer sponsored defined benefit pension and other postretirement benefit plans. Under ASU 2017-07, an entity must disaggregate and present the service cost component of net periodic benefit cost in the same income statement line item as other employee compensation costs arising from services rendered during the period, and only the service cost component will be eligible for capitalization. Other components of net periodic benefit cost will be presented separately from the line item that includes the service cost. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. Early adoption is permitted at the beginning of an annual period in which the financial statements have not been issued. Entities must use a retrospective transition method to adopt the requirement for separate presentation of the income statement service cost and other components, and a prospective transition method to adopt the requirement to limit the capitalization of benefit cost to the service component. As a result of the adoption of ASU 2017-07 in the first quarter of 2018, the Company reclassified $210,000 and $443,000 out of Operation and Maintenance expense and moved it to the “Other” line item in the “Other (Deductions) Income, Net of Taxes” section of the quarter to date and year to date, respectively, June 30, 2017 Condensed Consolidated Statement of Income to conform with the requirements of 2017-07.

In February 2018, the FASB issued ASU 2018-02, “Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income”, (ASU No. 2018-02) to help businesses and other organizations present some effects from the Tax Act’s reduction in the corporate tax rate in their income statements. ASU No. 2018-02 gives the option of reclassifying what are called the “stranded” tax effects within accumulated other comprehensive income to retained earnings during each fiscal year or quarter in which the effect of the lower tax rate is recorded. ASU No. 2018-02 instructs businesses and other organizations to provide a disclosure in their financial statement footnotes that describes the accounting policy they used to release the income tax effects from accumulated other comprehensive income, whether they are reclassifying the stranded income tax effects from the Tax Cut and Jobs Act, and information about the other effects on taxes from the reclassification. ASU 2018-02 is effective for all organizations for fiscal years that begin after December 15, 2018, and the quarterly and other interim periods in those years, with early adoption permissible. The Company adopted ASU No. 2018-02 effective December 31, 2017. The adoption of ASU No. 2018-02 resulted in an approximate $70,000 increase to Retained Earnings at December 31, 2017.

5. Revenues from Contracts with Customers

Accounting Policy

Our revenues are primarily from tariff-based sales. We provide water and wastewater services to customers under these tariffs without a defined contractual term (at-will).  As the revenue from these arrangements is based upon the amount of the water and wastewater services supplied and billed in that period (including estimated billings), there was not a shift in the timing or pattern of revenue recognition for such sales when compared to our revenue recognition prior to the adoption of ASU 2014-09.  We have also completed the evaluation of our other revenue streams, including those tied to longer term contractual commitments and the Company’s Linebacker program.

Customers are primarily billed quarterly on a cycle basis. To match revenues with associated expenses, we accrue unbilled revenues for water and wastewater services delivered to customers, but not yet billed at month end, creating a contract asset.

Nature of Goods and Services

Water Operations - We currently provide retail water and wastewater services to five primary customer classes. Our largest customer class consists of residential customers, which include single private dwellings and individual apartments. Our commercial class consists primarily of main street businesses, our industrial class consists primarily of manufacturing and processing businesses that turn raw materials into products, our public authority class represents services provided primarily to municipality or other government customers, and, finally, our fire protection class consists of services related to fire suppression systems and fire hydrants. Connecticut Water’s management has determined that tariff-based receipts; except for the WRA and other deferred revenue mechanisms, which are considered alternative revenue programs; are considered revenues from contracts with customers.

• The Company has performance obligations for the service of standing ready to deliver water to customers. The Company recognizes revenue at a fixed rate as it provides these services, as approved by regulators. These arrangements generally do not have fixed terms and remain in effect as long as the customer consumes the utility service. The rates are set by PURA and the MPUC through the rate-making process and represent the stand-alone selling price of Company’s service to stand ready to deliver.

• The Company has performance obligations for the service of delivering the commodity of water to customers. The Company recognizes revenue at a price per unit of water delivered (gallons, cubic feet, etc.), based on the tariffs established by our regulators. These arrangements generally do not have fixed terms and remain in effect as long as the customer consumes the utility service. The rates are set by PURA and the MPUC through the rate-making process and represent the stand-alone selling price of a bundled product comprising the commodity and the service of delivering such commodity.

• The Company has a performance obligation related to administrative services such as turn-on/turn-off services, assessment of late charges, etc. The Company views that these services are not distinct in the context of the contract because they are highly interdependent for the effective delivery of water service provided to consumers.

Based on the above discussion, the Company believes that the Goods and Services provided under customer contracts constitute a single performance obligation. The Company believes that this performance obligation is satisfied over time.

Services and Rentals - We provide contracted services to water utilities and other clients and also lease certain of our properties to third parties. The types of services provided include contract operations of water; Linebacker, our service line protection plan for public drinking water customers; and providing bulk deliveries of emergency drinking water to businesses and residences via tanker truck. Our lease and rental income comes primarily from the renting of residential and commercial property. The goods and services provided by Linebacker have been determined to be based on the stand ready nature of the Company to provide the goods and services and, therefore, customers simultaneously receive and consume the benefits provided by the Company. The other revenue streams in the Services and Rentals segment, including contracted services to water utilities and other clients, have performance obligations that are satisfied at a point in time, and likewise will not have a shift in the timing or pattern of revenue recognition.

Accrued Unbilled Revenues from Contracts with Customers	$	9,732	$	8,481

Accounts Receivable and Accrued Unbilled Revenues: Accounts receivable are comprised of trade receivables primarily from our regulated water customers. The Company records their accounts receivable at cost, which approximates fair value. Additionally, the Company establishes an allowance for uncollectible accounts based on historical losses, management’s assessment of existing economic conditions, customer payment trends, and other factors. The Company assesses late payment

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (continued)

fees on trade receivables based on contractual past-due terms established with customers and approved by PURA or the MPUC. The provision for bad debts is charged to operating expense.

The Company’s customers are primarily billed quarterly in cycles having billing dates that do not generally coincide with the end of a fiscal quarter. This results in customers having received water or waste water services that they have not been billed for as of a given period’s end. The Company estimates its unbilled revenues by applying an average billed rate to total unbilled deliveries for each customer class.

On January 10, 2017, Maine Water executed and delivered to CoBank a new Promissory Note and Single Advance Term Loan Supplement, dated January 10, 2017 (the “Third Promissory Note”). On the terms and subject to the conditions set forth in the Third Promissory Note issued pursuant to the Agreement, CoBank agreed to make an unsecured loan (the “Loan”) to Maine Water in the principal amount of $5,000,000 at 4.18%, due December 30, 2026. The proceeds of the Loan will be used to finance new capital expenditures and refinance existing debt owed to the Company, incurred in connection with general water system improvements.

On August 28, 2017, the Company executed and delivered to CoBank a new Promissory Note and Supplement (2017 Single Advance Term Loan) (the “2017 Promissory Note”). On the terms and subject to the conditions set forth in the 2017 Promissory Note issued pursuant to the Company’s Master Loan Agreement, CoBank agreed to make a term loan (the “Loan”) to the Company in the principal amount of $15,000,000. Under the 2017 Promissory Note, the Company will pay interest on the Loan at a fixed rate of 4.15% per year through August 20, 2037, the maturity date of the Loan.

On September 28, 2017, Connecticut Water completed the issuance of $35,000,000 aggregate principal amount of its 3.53% unsecured Senior Notes due September 25, 2037 (the “Senior Notes”). The Senior Notes were issued pursuant to the Note Purchase Agreement dated as of September 28, 2017 (the “Purchase Agreement”) between and among Connecticut Water, NYL Investors, LLC (“NY Life”), as agent, and the Purchasers listed in the Purchaser Schedule attached to the Purchase Agreement, in a private placement financing exempt from registration pursuant to Section 4(a)(2) of the Securities Act of 1933, as amended. The proceeds of the sale of the Senior Notes will be used by Connecticut Water to repay loans from the Company the proceeds of which were used for capital expenditure projects by Connecticut Water. The Senior Notes bear interest at the rate of 3.53% per annum, payable semi-annually on March 27 and September 27 of each year commencing on March 27, 2018. The principal amount of the Senior Notes, if not previously paid, shall be due on September 25, 2037. The Senior Notes are callable in whole or in part, subject to a make-whole amount.

Financial Covenants – The Company and its subsidiaries are required to comply with certain covenants in connection with various long term loan agreements.  The most restrictive of these covenants is to maintain a consolidated debt to capitalization ratio of not more than 60%. Additionally, Maine Water has restrictions on cash dividends paid based on restricted net assets. The Company and its subsidiaries were in compliance with all covenants at June 30, 2018.

8. Fair Value Disclosures

FASB Accounting Standards Codification (“ASC”) 820, Fair Value Measurements and Disclosures (“FASB ASC 820”) provides enhanced guidance for using fair value to measure assets and liabilities and expands disclosure with respect to fair value measurements.

FASB ASC 820 establishes a fair value hierarchy that distinguishes between assumptions based on market data (observable inputs) and the Company’s assumptions (unobservable inputs).  The hierarchy consists of three broad levels, as follows:

Level 1 – Quoted market prices in active markets for identical assets or liabilities.

Level 2 – Inputs other than Level 1 that are either directly or indirectly observable.

Level 3 – Unobservable inputs developed using the Company’s estimates and assumptions, which reflect those that the Company believes market participants would use.

(2) Mutual funds consist primarily of fixed income securities and are presented on the Other Property and Investments line item of the Company’s Condensed Consolidated Balance Sheets.

The following methods and assumptions were used to estimate the fair value of each of the following financial instruments, which are not recorded at fair value on the financial statements.

Cash and cash equivalents – Cash equivalents consist of highly liquid instruments with original maturities at the time of purchase of three months or less.  The carrying amount approximates fair value.  Under the fair value hierarchy the fair value of cash and cash equivalents is classified as a Level 1 measurement.

Company Owned Life Insurance – The fair value of Company Owned Life Insurance is based on the cash surrender value of the contracts. These contracts are based principally on a referenced pool of investment funds that actively redeem shares and are observable and measurable and are presented on the “Other Property and Investments” line item of the Company’s Consolidated Balance Sheets. The value of Company Owned Life Insurance at June 30, 2018 and December 31, 2017 was $4,098,000 and $4,018,000, respectively.

Long-Term Debt – The fair value of the Company’s fixed rate long-term debt is based upon borrowing rates currently available to the Company.  As of June 30, 2018 and December 31, 2017, the estimated fair value of the Company’s long-term debt was $258,051,000 and $268,628,000, respectively, as compared to the carrying amounts of $256,357,000 and $258,272,000, respectively. The estimated fair value of long term debt was calculated using a discounted cash flow model that uses comparable interest rates and yield curve data based on the A-rated MMD (Municipal Market Data) Index which is a benchmark of current municipal bond yields. Under the fair value hierarchy, the fair value of long term debt is classified as a Level 2 measurement.

Advances for Construction – Customer advances for construction had a carrying amount of $19,560,000 and $20,024,000 at June 30, 2018 and December 31, 2017, respectively. Their relative fair values cannot be accurately estimated since future refund payments depend on several variables, including new customer connections, customer consumption levels and future rate increases.

The fair values shown above have been reported to meet the disclosure requirements of FASB ASC 825, “Financial Instruments” (“FASB ASC 825”) and do not purport to represent the amounts at which those obligations would be settled.

10. Income Taxes

FASB ASC 740 Income Taxes (“FASB ASC 740”) addresses the determination of how tax benefits claimed or expected to be claimed on a tax return should be recorded in the financial statements. Under FASB ASC 740, the Company must recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate resolution.

The Company adopted the Internal Revenue Service (“IRS”) temporary tangible property regulations on the Company’s 2012 Federal tax return. Since that time, the Company has been recording a provision for any possible disallowance of a portion of the repair deduction if the Company’s Federal tax return were to be reviewed by the IRS. While the Company believes that the deductions taken on its tax returns are appropriate, the methodology for determining the deduction has not been agreed to by the taxing authorities.  During the Company’s review of the position through the quarter ended March 31, 2017, new information caused management to reassess the previously recorded provision. This reassessment resulted in the reversal of a portion of the provision related to the Maine subsidiary, in the amount of $1,164,000 in the first quarter of 2017. During the Company’s review of the position through the quarter ended June 30, 2017, the impact of the new information on the Connecticut subsidiary caused management to reassess the previously recorded provision. The reassessment resulted in the reversal of a portion of the provision in the amount of $2,445,000. Through June 30, 2017, the Company has recorded, as required by FASB ASC 740, a provision of $725,000 for a portion of the benefit that is not being returned to customers resulting from any possible tax authority challenge. For the six months endedJune 30, 2018, the Company recorded a provision of $530,000 for a portion of the benefit that is not being returned to customers resulting from any possible tax authority challenge. The Company had previously recorded a provision of $4.6 million in prior years for a cumulative total of $5.1 million.

On December 22, 2017, H.R. 1, originally known as the Tax Cuts and Jobs Act, (the “Tax Act”) was enacted. Among the significant changes to the U.S. Internal Revenue Code, the Tax Act lowered the U.S. federal corporate income tax rate (“Federal Tax Rate”) from 35% to 21% effective January 1, 2018. In December 2017, the Securities and Exchange Commission staff issued Staff Accounting Bulletin No. 118, which addresses how a company recognizes provisional amounts when a company does not have the necessary information available, prepared or analyzed (including computations) in reasonable detail to complete its accounting for the effect of the changes in the Tax Act. The measurement period ends when a company has obtained, prepared and analyzed the information necessary to finalize its accounting, but cannot extend beyond one year. While we are able to make reasonable estimates of the impact of the reduction in corporate rate, the final impact of the Tax Act may differ from these estimates, due to, among other things, changes in our interpretations and assumptions, additional guidance that may be issued by the I.R.S., and actions we may take. We are continuing to gather additional information to determine the final impact. Provisional amounts have been recorded as a Regulatory Liability to the extent that the tax savings over time will be returned to customers in utility rates, and a non-cash adjustment was recognized to record additional income tax expense to the extent revalued deferred income taxes are not believed to be recoverable in utility customer rates. Accounting for the income tax effects of the Tax Act is expected to be completed when a decision is reached by both PURA and the MPUC regarding the impact that shall be included in utility customer rates. During the first half of 2018, the Company performed further analysis on the impact of the enacted legislation.  Through the quarter ended June 30, 2018, the Company recorded an excess accumulated deferred tax liability of $31 million, of which $28 million relates to the Tax Act.  The additional analysis resulted in no change to the Unrecovered Income Taxes and Unfunded Future Income Taxes or income tax expense.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (continued)

From time to time, the Company may be assessed interest and penalties by taxing authorities.  In those cases, the charges would appear on the Other line item within the Other Income (Deductions), Net of Taxes section of the Company’s Condensed Consolidated Statements of Income.  There were no such charges for the six months endedJune 30, 2018 and 2017.  Additionally, there were no accruals relating to interest or penalties as of June 30, 2018 and December 31, 2017.  The Company remains subject to examination by federal and state tax authorities for the 2014 through 2016 tax years. On April 26, 2017, Avon Water was notified by the IRS that its stand-alone Federal tax filing for 2015 was selected to be reviewed beginning in the second quarter of 2017 and the audit was expanded to include the 2016 standalone tax year. On March 20, 2018, Avon Water received a notice of adjustment from the IRS related to the Federal tax audit for the tax years ended December 31, 2015 and 2016. As a result, a reduction in the net operating loss carryover of $56,000 was recorded during the six months ended June 30, 2018.

The Company is currently engaged in an analysis to determine the amount of expenditures related to tangible property that will be reflected on its 2018 Federal Tax Return to be filed in September 2019.  As a result, through the second quarter of 2018, the Company has estimated the portion of its infrastructure investment that will qualify as a repair deduction for 2018 and has reflected that deduction in its effective tax rate, net of any reserves.  Consistent with other differences between book and tax expenditures, the Company is required to use the flow-through method to account for any timing differences not required by the IRS to be normalized.

The Company’s effective income tax rate for the three months endedJune 30, 2018 and 2017 was 10.7% and (10.5)%, respectively. The Company’s effective tax rate, excluding discrete items recorded during the three months endedJune 30, 2018 and 2017, was (6.8)% and 16.2%, respectively. In 2018, these discrete items include adjustments related to uncertain tax positions for the repair deduction in Connecticut and purchase accounting adjustments to goodwill. In 2017, these discrete items include adjustments related to uncertain tax positions for the repair deduction in Connecticut. Excluding discrete items, there was a decrease in the effective tax rate year over year for the three month period of approximately 23%. The decrease in the effective tax rate for this period can be attributed to a higher estimated repair deduction, higher tax deductible pension contribution and higher performance stock deduction in 2018 than in 2017. The Company’s effective income tax rate for the six months endedJune 30, 2018 and 2017 was 11.7% and (7.1)%, respectively. The Company’s effective tax rate, excluding discrete items recorded during the six months endedJune 30, 2018 and 2017, was (18.0)% and 17.7%, respectively. In 2018, these discrete items include adjustments related to uncertain tax positions for the repair deduction in Connecticut, purchase accounting adjustments to goodwill, an IRS audit adjustment, and adjustments required under the Tax Act. In 2017, these discrete items include adjustments related to uncertain tax positions for the repair deduction in Connecticut. Excluding discrete items, there was a decrease in the effective tax rate year over year for the six month period of approximately 36%. The decrease in the effective tax rate for this period can be attributed to a higher estimated repair deduction, higher tax deductible pension contribution and higher performance stock deduction in 2018 than in 2017. The blended Federal and State statutory income tax rates during the three and six months endedJune 30, 2018 and 2017 were 28% and 41%, respectively. In determining its annual estimated effective tax rate for interim periods, the Company reflects its estimated permanent and flow-through tax differences for the taxable year, including the basis difference for the adoption of the tangible property regulations.

11. Lines of Credit

As of June 30, 2018, the Company maintained a $15.0 million line of credit agreement with CoBank, that is currently scheduled to expire on July 1, 2020.  The Company maintained an additional line of credit of $45.0 million with Citizens Bank, N.A., with an expiration date of April 25, 2021.  Additionally, Avon Water maintains a $3.0 million line of credit with Northwest Community Bank, with an expiration date of September 30, 2018. As of June 30, 2018, the total lines of credit available to the Company were $63.0 million.  As of June 30, 2018 and December 31, 2017, the Company had $42.9 million and $19.3 million, respectively, of Interim Bank Loans Payable. As of June 30, 2018, the Company had $20.1 million in unused lines of credit.  Interest expense charged on lines of credit will fluctuate based on market interest rates.

The estimated fair values of the assets acquired and the liabilities assumed were determined based on the accounting guidance for fair value measurement under GAAP, which defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value analysis assumes the highest and best use of the assets by market participants. The allocation of the purchase price includes an adjustment to fair value related to the fair value of HVWC’s and Avon Water’s long term debt and any associated deferred taxes. Additionally, adjustments were made to deferred taxes based on the Company’s ability to utilize net operating loss carryforwards that had valuation allowances at the acquired companies. The excess of the purchase price paid over the estimated fair value of the assets acquired and the liabilities assumed was recognized as goodwill, none of which is deductible for tax purposes. Goodwill recognized as part of the acquisitions of HVWC and Avon Water are a part of the Company’s Water Operations segment.

Part I, Item 2: Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion should be read in conjunction with the accompanying unaudited financial statements and related notes thereto and the audited financial statements and the notes thereto contained in our Annual Report on Form 10-K for the year ended December 31, 2017.

General Information

Proposed Merger with SJW Group

On August 5, 2018, the Company entered into a Second Amended and Restated Agreement and Plan of Merger (the “Revised Merger Agreement”) with SJW Group, a Delaware corporation (“SJW”), and Hydro Sub, Inc., a Connecticut corporation and a direct wholly owned subsidiary of SJW (“Merger Sub”), pursuant to which Merger Sub will merge with and into the Company, with the Company surviving the Merger as a wholly owned subsidiary of SJW (the “Merger”). Subject to the terms and conditions of the Revised Merger Agreement, at the effective time of the Merger, each outstanding share of our common stock (other than certain cancelled shares) will be automatically converted into the right to receive an amount in cash equal to $70.00 per share, payable without interest. The Revised Merger Agreement amends and restates in its entirety the Amended and Restated Agreement and Plan of Merger (the “First Amended and Restated Merger Agreement”), dated as of May 30, 2018, by and among the Company, SJW and Merger Sub, which amended and restated in its entirety the Agreement and Plan of Merger (the “Original Merger Agreement”), dated as of March 14, 2018, by and among the Company, SJW and Merger Sub.

The Board of Directors approved, adopted and declared advisable and resolved to recommend to the Company’s shareholders the approval of the Revised Merger Agreement and the Merger following a comprehensive review of the transaction.

The Merger is subject to certain customary closing conditions, including, among other things, approval of the Revised Merger Agreement by the Company’s shareholders and regulatory approvals (including the approval of the Connecticut Public Utilities Regulatory Authority (“PURA”) and the Maine Public Utilities Commission (“MPUC”) and pre-approvals of any license transfers from the Federal Communications Commission). The required waiting period under the Hart-Scott-Rodino Antitrust

28

Improvements Act of 1976, as amended, and the rules and regulations promulgated thereunder (the “HSR Act”), was terminated early on April 27, 2018.

On May 4, 2018, Maine Water filed with the MPUC an application for approval of the Merger. On May 7, 2018, the Company and SJW filed with the PURA a joint application for approval of the Merger. Following the start on May 31, 2018 of a 45-day go-shop process permitted by the First Amended and Restated Merger Agreement, the Company and SJW withdrew their joint application on June 19, 2018, and filed a new joint application on July 18, 2018, following the end of the go-shop process.

On July 20, 2018, the California Public Utilities Commission (“CPUC”) formally issued an Order Instituting Investigation (“Order”) providing that the CPUC will investigate whether the Merger is subject to CPUC approval and the Merger’s anticipated impacts within California. The Order states that the CPUC plans to substantially complete its investigation in a manner sufficiently timely to allow the Merger to go forward by the end of 2018, if appropriate.

The Company and SJW expect the closing of the Merger to occur during the first quarter of 2019.

Regulatory Matters

The rates we charge our water and waste water customers in Connecticut and Maine are established under the jurisdiction of and are approved by PURA and the MPUC, respectively. It is our policy to seek rate relief as necessary to enable us to achieve an adequate rate of return. The Regulated Companies’ allowed returns on equity and allowed returns on rate base are as follows:

As of June 30, 2018	Allowed Return on Equity		Allowed Return on Rate Base
Connecticut Water	9.75	%	7.32	%
HVWC (blended water and wastewater rates)	10.10	%	7.19	%
Avon Water	10.00	%	7.79	%
Maine Water	9.50	%	7.96	%

The PURA establishes rates in Connecticut on a company-wide basis while the MPUC approves Maine Water’s rates on a division-by-division basis. Each of Connecticut Water, HVWC, Avon Water and Maine Water are allowed to add surcharges to customers’ bills in order to recover certain costs associated with approved capital projects in between full rate cases, as well as approved surcharges for Water Revenue Adjustments, in Connecticut, as discussed in more detail below. HVWC has not added surcharges to customers’ bills in order to recover certain approved capital projects as of June 30, 2018, however, HVWC, as ordered by PURA, began to utilize Water Revenue Adjustments as of March 31, 2017.

On January 3, 2018, PURA filed a motion to reopen the most recent rate case decisions for the Company’s Connecticut Regulated Companies to determine what, if any, adjustments to rates are appropriate to account for revisions to tax laws, including corporate tax rates, contained in the Tax Cuts and Jobs Act (“Tax Act”). PURA held a hearing on July 30, 2018 for regulated water companies. As discussed below, Connecticut Water has entered into a settlement agreement with the Connecticut Office of Consumer Counsel (“OCC”) that covers treatment of the Tax Act.

On January 11, 2018, the MPUC issued a notice of investigation to determine the impact of the Tax Act on Maine Water. The investigation will allow the MPUC to determine the specific impact of the Tax Act and whether any rate adjustments are warranted. Following discovery, technical conferences were held on April 19, 2018 and July 17, 2018. The current schedule for the investigation anticipates a report by the Hearing Examiner on August 13, 2018. In addition to determining the impact of the Tax Act on the justness and reasonableness of Maine Water’s rates, the MPUC will consider whether to issue an accounting order to establish a regulatory liability which defers for future flow-through to ratepayers the impact of the tax changes.

The Heritage Village Water Company Acquisition

On May 10, 2016, the Company announced that it had reached an agreement to acquire HVWC, pending a vote of HVWC shareholders, approval by PURA and MPUC and the satisfaction of other various closing conditions, pursuant to the terms of Agreement and Plan of Merger dated May 10, 2016 between and among HVWC, the Company, and HAC, Inc., the Company’s wholly-owned Connecticut subsidiary (the “Merger Agreement”). HVWC serves approximately 4,700 water customers in the Towns of Southbury, Middlebury, and Oxford, Connecticut and approximately 3,000 wastewater customers in the Town of Southbury, Connecticut.

29

The acquisition was executed through a stock-for-stock merger transaction valued at approximately $16.9 million. Holders of HVWC common stock received shares of the Company’s common stock in a tax-free exchange. In addition, the transaction reflected a total enterprise value of HVWC of approximately $21.5 million, with the $16.9 million paid to shareholders in a stock exchange and the assumption by the Company of approximately $4.6 million of debt held by HVWC at the time of the acquisition.

The Company received regulatory approval from MPUC on September 28, 2016 and from PURA on December 5, 2016, to proceed with the transaction. The shareholders of HVWC voted to approve the acquisition at a special meeting of HVWC’s shareholders held on February 27, 2017.

On February 27, 2017, the Company completed the acquisition of HVWC by completing the merger of the Company’s wholly-owned subsidiary HAC, Inc. with and into HVWC, with HVWC as the surviving corporation, pursuant to the terms of the Merger Agreement and Connecticut corporate law. Upon the effective time of the Merger, the holders of HVWC’s 1,620 issued and outstanding shares of common stock became entitled to receive an aggregate of 300,445 shares of the Company’s common stock in a tax-free exchange, which exchange was commenced promptly by the issuance of a letter of transmittal and related materials by Connecticut Water’s exchange agent.

The Avon Water Company Acquisition

On October 12, 2016, the Company announced that it had reached an agreement to acquire Avon Water, pending a vote of Avon Water shareholders, approval by PURA and the MPUC and the satisfaction of other various closing conditions, pursuant to the terms of that certain Agreement and Plan of Merger dated October 11, 2016 as amended on March 29, 2017 between and among Avon Water, the Company, and WC-A I, Inc., the Company’s wholly-owned Connecticut subsidiary (the “Merger Agreement”). Avon Water serves approximately 4,800 customers in the Farmington Valley communities of Avon, Farmington, and Simsbury, Connecticut.

On February 10, 2017, Connecticut Water received regulatory approval from MPUC and on April 12, 2017, Connecticut Water received regulatory approval from PURA to proceed with the transaction. The shareholders of Avon Water voted to approve the acquisition at a special meeting of Avon Water’s shareholders held on June 16, 2017.

Effective July 1, 2017, the Company completed the acquisition of Avon Water by completing the merger of Connecticut Water’s wholly-owned subsidiary WC-A I, Inc. with and into Avon Water, with Avon Water as the surviving corporation, pursuant to the terms of the Merger Agreement and Connecticut corporate law. Upon the effective time of the Merger, the holders of Avon Water’s 122,289 issued and outstanding shares of common stock became entitled to receive the following merger consideration for each share of Avon Water common stock held: (i) a cash payment of $50.11; and (ii) a stock consideration component, consisting of 3.97 shares of the Company’s common stock.

The transaction was completed through a stock-for-stock exchange where Avon Water shareholders received the Company’s common stock valued at approximately $26.9 million, in a tax-free exchange, and a cash payment of $6.1 million for a total payment to shareholders of $33.0 million. The transaction reflects a total enterprise value of approximately $39.1 million, with the $33.0 million paid to shareholders and the assumption by the Company of approximately $6.1 million of debt of Avon Water.

Maine Water Land Sale

On March 11, 2016, Maine Water entered into a purchase and sale agreement with the Coastal Mountains Land Trust, a Maine nonprofit corporation (the “Land Trust”) pursuant to which Maine Water agreed to sell two conservation easements to the Land Trust on approximately 1,300 acres of land located in the towns of Rockport, Camden and Hope, in Knox County, Maine valued in the aggregate at $3.1 million.  The land had a book value of approximately $600,000 at June 30, 2018 and December 31, 2017 and is included in “Utility Plant” on the Company’s Consolidated Balance Sheets. The easements and purchase prices are as follows:

1.Ragged Mountain Mirror Lake Conservation Easement: $1,875,000; and

2.Grassy Pond conservation Easement: $600,000.

On June 25, 2018, an amendment to the agreement was made to extend closing of the first transaction to September 30, 2018, from June 30, 2018.  This is also expected to extend the second closing into 2020.  Maine Water will make a $250,000 contribution to the Land Trust upon completion of the closing of the first easement sale.  Maine Water also expects to claim a charitable deduction for the $600,000 in excess of the fair market value of the second easement over the $600,000 sale price.

Connecticut Rates

Connecticut Water’s Water Infrastructure Conservation Adjustment (“WICA”) was 9.98% and 8.25% at June 30, 2018 and 2017, respectively. As of June 30, 2018, Avon Water’s WICA surcharge was 7.51%. As of June 30, 2018, HVWC has not filed for a WICA surcharge.

On February 6, 2018, Connecticut Water filed a petition with PURA to reopen Connecticut Water’s 2010 rate case (previously reopened in 2013) proceeding for the limited purpose of approving a Settlement Agreement entered into by Connecticut Water and the OCC (the “Agreement”). The Agreement proposes a change in Connecticut Water’s customer rates effective for bills rendered on and after April 1, 2018 made up of the following two components: (1) the revenue requirements associated with a $36.3 million addition to rate base to reflect necessary upgrades to Connecticut Water’s Rockville Water Treatment Plant; and (2) the folding in to base rates of the Company’s present WICA surcharges. In addition, the Agreement provides that:

1. Upon implementation of new rates under the Agreement, until such time as new rates are adopted in a general rate case, through a temporary modification of the earnings sharing mechanism, Connecticut Water customers will receive one hundred percent of any earnings in excess of levels allowed by law rather than limiting such customer credits to 50% as contemplated by applicable law;

2. Connecticut Water agrees it will not file for a general increase of Connecticut Water’s base rates to be effective before January 1, 2020;

3. The pending proceeding initiated by PURA in Docket No. 09-12-11RE03, Application of The Connecticut Water Company for Amended Rates – Federal Tax Cuts and Jobs Act shall be closed; and

4. Connecticut Water shall continue to make investments in infrastructure replacement consistent with its approved WICA plan. Connecticut Water shall be allowed to continue to pursue recovery of eligible projects through WICA.

The Agreement provides that, if PURA does not fully approve the Agreement in its entirety, it shall be deemed withdrawn.  Accordingly, the Agreement has no operative effect unless and until it is approved by PURA.  No assurance can be given that PURA will approve the Agreement and permit some or all of the terms contained in the Agreement requested by the parties.  PURA has agreed to the request to reopen the rate proceeding.  PURA issued a Proposed Final Decision on July 6, 2018 that rejected the Settlement Agreement, due to the proposed treatment of income tax expense resulting from the Tax Act. The Company and the Office of Consumer Council each filed written exceptions to the draft decision and a hearing was held on a revised settlement agreement submitted from both parties that would include an adjustment to reflect the impacts of the Tax Act but at a lower dollar amount than recommended in the PURA draft decision.  A final decision is anticipated from PURA in August with implementation of new rates to immediately follow.

Since 2013, Connecticut law has authorized a Water Revenue Adjustment (“WRA”) to reconcile actual water revenues with the revenues projected in the last general rate case and allows companies to adjust rates as necessary to recover the revenues approved by PURA in the last 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. Additionally, projects eligible for WICA surcharges were expanded to include energy conservation projects, improvements required to comply with streamflow regulations, and improvements to certain acquired systems.

Connecticut Water and HVWC’s allowed revenues for the six months endedJune 30, 2018, as approved by PURA during each company’s most recent general rate case and including subsequently approved WICA surcharges, are approximately $38.7 million. Through normal billing for the six months endedJune 30, 2018, revenue for Connecticut Water and HVWC would have been approximately $35.2 million had the WRA not been implemented. As a result of the implementation of the WRA, Connecticut Water and HVWC recorded $3.5 million in additional revenue for the six months endedJune 30, 2018. Avon Water does not currently use the WRA mechanism. Avon Water does not currently have PURA approval to apply the WRA surcharge to their customers’ bills.

Maine Rates

In Maine, the overall, cumulative Water Infrastructure Charge (“WISC”) for all divisions was 6.8% and 5.7% as of June 30, 2018 and 2017, respectively. The WISC rates for the Biddeford and Saco division were reset to zero with the approval of the general rate increase discussed below.

On June 29, 2017, Maine Water filed for a rate increase in its Biddeford and Saco division. The rate request was for an approximate $1.6 million, or 25.1%, increase in revenues. The rate request is designed to recover higher operating expenses, depreciation and property taxes since Biddeford and Saco’s last rate increase in 2015. Maine Water and the Maine Office of the Public Advocate reached an agreement that increases annual revenue by $1.56 million. The agreement was approved by the MPUC on December 5, 2017, with new rates effective December 1, 2017.

31

A water revenue adjustment mechanism law in Maine became available to regulated water utilities in Maine on October 15, 2015. Maine Water is currently precluded from seeking new rates in the Biddeford and Saco division due to provisions in the settlement agreement with the MPUC. As the stay-out periods for other divisions expire, Maine Water expects to request usage of this mechanism as Maine Water file rate cases for those divisions.

Critical Accounting Policies and Estimates

The Company maintains its accounting records in accordance with accounting principles generally accepted in the United States of America and as directed by the PURA and the MPUC, to which the Company’s regulated water utility subsidiaries are subject.  Significant accounting policies employed by the Company, including the use of estimates, were presented in the Notes to Consolidated Financial Statements of the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017.

Critical accounting policies are those that are the most important to the presentation of the Company’s financial condition and results of operations.  The application of such accounting policies requires management’s most difficult, subjective, and complex judgments and involves uncertainties and assumptions.  The Company’s most critical accounting policies pertain to public utility regulation related to ASC 980 “Regulated Operations”, revenue recognition (including the WRA), goodwill impairment, income taxes and accounting for pension and other post-retirement benefit plans.  Each of these accounting policies and the application of critical accounting policies and estimates were discussed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017.

Management must use informed judgments and best estimates to properly apply these critical accounting policies.  Because of the uncertainty in these estimates, actual results could differ from estimates used in applying the critical accounting policies.  The Company is not aware of any reasonably likely events or circumstances which would result in different amounts being reported that would materially affect its financial condition or results of operations.

Outlook

The following modifies and updates the “Outlook” section of the Company’s 2017 Annual Report on Form 10-K for the fiscal year ended December 31, 2017.

The Company’s earnings and profitability are primarily dependent upon the sale and distribution of water. The water revenues of Maine Water and Avon Water can be dependent on seasonal weather fluctuations, particularly during the summer months when water demand will vary with rainfall and temperature levels. This risk has been mitigated by Connecticut Water and HVWC with the implementation of the WRA. The Company’s earnings and profitability in future years will also depend upon a number of other factors, such as the ability to control our operating costs, customer growth in the Company’s core regulated water utility businesses, growth in revenues attributable to non-water sales operations, availability and desirability of land no longer needed for water delivery for land sales, and the timing and adequacy of rate relief when requested, from time to time, by our regulated water companies.

The Company expects Net Income from its Water Operations segment to decrease in 2018 over 2017 levels, primarily due to costs associated with the merger with SJW. Partially offsetting these costs, the Company expects accretive effects of the HVWC acquisition, completed on February 27, 2017, and the Avon Water acquisition, completed on July 1, 2017, and revenue increases resulting from the recently issued Biddeford and Saco rate decision and increased surcharges related to WISC in Maine and WICA in Connecticut.

The Company believes that the factors described above and those described in detail under the heading “Commitments and Contingencies” below may have significant impact, either alone or in the aggregate, on the Company’s earnings and profitability in fiscal years 2018 and beyond.  Please also review carefully the risks and uncertainties described in the sections entitled Item 1A – Risk Factors, “Commitments and Contingencies” in Item 7 of the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017 and the risks and uncertainties described in the “Forward-Looking Information” section below.

Results of Operations

Three months ended June 30

Net Income for the three months endedJune 30, 2018 decreased from the same period in the prior year by $3,689,000 to $4,729,000. Earnings per basic average common share were $0.39 and $0.75 during the three months ended June 30, 2018 and 2017, respectively. The primary driver for the decrease in Net Income was the approximately $2.4 million in after-tax costs associated with the announced merger with SJW.

This decrease is broken down by business segment as follows (in thousands):

Business Segment	June 30, 2018		June 30, 2017		Increase/(Decrease)
Water Operations	$	4,297	$	8,086	$	(3,789	)
Real Estate Transactions	—		—		—
Services and Rentals	432		332		100
Total	$	4,729	$	8,418	$	(3,689	)

The Net Income from Water Operations for the three months endedJune 30, 2017 were impacted positively by a partial reversal of previously established tax provisions. During the three months endedJune 30, 2017, new information caused the Company to undertake a review of its provision recorded associated with the repair deduction. While the Company maintains the belief that the deduction taken on its tax return is appropriate, the methodology for determining the deduction has not been agreed to by the taxing authorities.  During the Company’s review of the position through the quarter ended June 30, 2017, the impact of new information on Connecticut Water caused management to reassess the previously recorded provision. The reassessment resulted in the reversal of a portion of the provision in the amount of $2,445,000.

Revenue

Revenue from our regulated customers increased by $2,002,000, or 7.2%, to $29,904,000 for the three months endedJune 30, 2018 when compared to the same period in 2017.  Approximately $1,072,000 of the increase in revenues was related to the acquisition of Avon Water on July 1, 2017. Excluding the impact of Avon Water, the Company saw an approximate $930,000 increase in revenues primarily related to increased WICA and WISC surcharges, as well as the increase in rates, effective December 1, 2017, in the Biddeford and Saco division of Maine Water.

33

Operation and Maintenance Expense

Operation and Maintenance (“O&M”) expense increased by $1,304,000, or 11.4%, for the three months ended June 30, 2018 when compared to the same period of 2017. The major reason for the increase was the impact on O&M expense related to the acquisition of Avon Water during 2017, which contributed $577,000 to the increase in O&M expense during the period. Note that HVWC was owned by the Company in the second quarter of both 2018 and 2017 and has therefore been included in the June 30, 2018 and the June 30, 2017 columns below. The following table presents the components of O&M expense for the three months ending June 30, 2018 and 2017, both including and excluding the impact of the Avon Water acquisition on July 1, 2017, (in thousands):

Expense Components	June 30, 2018		June 30, 2017		Increase / (Decrease)			Avon Water O&M Impact			Adjusted Increase/(Decrease)

Total	$	12,720	$	11,416	$	1,304		$	577		$	727

The increase in O&M expenses excluding the O&M impact of the acquisition of Avon Water, was approximately $727,000, or approximately 6.4%, in the three months endedJune 30, 2018 when compared to the same period in 2017.  The changes in individual items, excluding the impact of HVWC and Avon Water, are described below:

• Payroll costs increased primarily due to more employee time being charged to capital projects in 2017 than in 2018, and therefore less to O&M expense, and higher wages paid in the three months endedJune 30, 2018 compared to the three months endedJune 30, 2017;

• Medical costs increased in three months endedJune 30, 2018 compared to the three months endedJune 30, 2017 primarily due to an increase in costs associated with claims filed by employees and their families and the costs associated with the administration of the Company’s medical plans;

• Outside services increased primarily as a result of higher non-merger related consulting and auditing fees in the three months endedJune 30, 2018 when compared to the same period in 2017; and

• Utility costs increased in the period primarily due to an increase in communication and electrical costs, partially offset by a decrease in fuel oil costs.

The increases described above were partially offset by the following decreases to O&M expense:

• Other benefits increased primarily due to lower costs associated with stock awards granted to certain named executives as well as an increase in capitalized benefits, which reduces O&M expense;

• Investor relations decreased due to lower costs associated with directors fees, primarily due to timing, and a reduction in costs associated with the Company’s transfer agent;

• Overall, Pension and Post-retirement benefit costs increased in the period due to a decrease in discount rates; however, due to the application of ASU 2017-07, which requires that a portion of these costs are moved out of O&M expense to the “Other” line in the Consolidated Statements of Net Income, the amount reclassified out of O&M expense in 2017 was greater than the corresponding amount in 2018, causing a decrease in the Pension and an increase Post-retirement medical lines of O&M expense; and

• Customer costs decreased primarily due to a reduction in uncollectible accounts and costs associated with a voluntary water conservation program that rewards customers for reducing their consumption by 10%.

The Company saw an approximate $376,000, or 9.4%, increase in its Depreciation expense for the three months endedJune 30, 2018 compared to the same period in 2017.  Of this increase, approximately $265,000 was attributable to the acquisition of Avon Water on July 1, 2017. The remaining increase was primarily due to higher Utility Plant in Service as of June 30, 2018 compared to June 30, 2017, driven by the completion of a large treatment plant in Connecticut in the second quarter of 2017 and continued spending on WICA and WISC projects in Connecticut and Maine, respectively.

The Company incurred $627,000 in above-the-line Income Taxes in the three months endedJune 30, 2018 compared to a $624,000 benefit in the same period of 2017. The primary reason for the change in the three months ended June 30, 2017 was the Company’s review of the provision recorded related to tangible property regulations through the quarter ended June 30, 2017. New information caused management to change its previously estimated reserve for uncertain tax positions related to the adoption of the tangible property regulation. This change in estimate resulted in the reversal of a portion of the provision in the amount of $2,445,000 in the three months ended June 30, 2017. Additionally, Income Tax expense of approximately $343,000 related to the impact of the Avon Water acquisition.

Other Income (Deductions), Net of Taxes decreased for the three months endedJune 30, 2018 by $1,935,000. The primary driver of this decrease was after-tax costs associated with the announced merger with SJW, which were $2,391,000 in the quarter ending June 30, 2018. Additionally, the Company saw a decrease in AFUDC due to the completion of a large treatment plant in the second quarter of 2017. Partially offsetting these decreases was an increase in Non-Water Sales earnings during the three months endedJune 30, 2018.

Total Interest and Debt Expense increased by $742,000 in the three months endedJune 30, 2018 when compared to the same period in 2017. Of this increase, approximately $64,000 was attributable to the acquisition of Avon Water. The remaining increase was primarily due to higher debt balances outstanding and increased borrowing under our lines of credit at June 30, 2018 when compared to June 30, 2017 and the aforementioned completion of a large treatment plant in the second quarter of 2017 resulting in lower capitalized interest costs in 2018.

Six months ended June 30

Net Income for the six months endedJune 30, 2018 decreased from the same period in the prior year by $8,984,000 to $3,502,000. Earnings per basic average common share decreased by $0.82 to $0.29 during the six months endedJune 30, 2018 primarily due to increased costs associated with the merger with SJW in 2018 and tax benefits recognized in 2017 as a result of a reversal of tax provisions related to tangible property tax regulations.

This decrease in Net Income is broken down by business segment as follows (in thousands):

Business Segment	June 30, 2018		June 30, 2017		Increase/(Decrease)
Water Operations	$	2,674	$	11,863	$	(9,189	)
Real Estate Transactions	—		33		(33		)
Services and Rentals	828		590		238
Total	$	3,502	$	12,486	$	(8,984	)

The Net Income from Water Operations for the six months endedJune 30, 2017 were impacted positively by a partial reversal of previously established tax provisions and a non-recurring expense reduction, respectively. During the six months endedJune 30, 2017, new information caused the Company to undertake a review of its provision recorded associated with the repair deduction. While the Company maintains the belief that the deduction taken on its tax return is appropriate, the methodology for determining the deduction has not been agreed to by the taxing authorities.  During the Company’s review of the position through the quarter ended March 31, 2017, new information caused management to reassess the previously recorded provision. This reassessment resulted in the reversal of a portion of the provision related to the Maine subsidiary, in the amount of $1,164,000 in the first quarter of 2017. During the Company’s review of the position through the quarter ended June 30, 2017, the impact of new information on Connecticut Water caused management to reassess the previously recorded provision. The reassessment resulted in the reversal of a portion of the provision in the amount of $2,445,000, for a total reversal of $3,609,000 during the six months ended June 30, 2017.

Revenue

Revenue from our regulated customers increased by $4,392,000, or 8.7%, to $54,757,000 for the six months endedJune 30, 2018 when compared to the same period in 2017. Approximately $2,702,000 of the increase in revenues was related to the acquisitions of HVWC and Avon Water on February 27, 2017 and July 1, 2017, respectively. The primary driver for the remaining increase was the use of the higher WISC and WICA surcharges in Maine and Connecticut, respectively, as well as the increase in rates, effective December 1, 2017, in the Biddeford and Saco division of Maine Water during the six months endedJune 30, 2018.

Operation and Maintenance Expense

O&M expense increased by $3,321,000, or 14.8%, for the six months endedJune 30, 2018 when compared to the same period of 2017, including the impact of O&M expense incurred after the acquisitions of HVWC and Avon Water on February 27, 2017 and July 1, 2017, respectively, which contributed $1,781,000 of incremental O&M expense during the period. The following table presents the components of O&M expense for the six months endedJune 30, 2018 and 2017, both including and excluding the impact of the HVWC and Avon Water acquisitions (in thousands):

Expense Components	June 30, 2018		June 30, 2017		Increase / (Decrease)			HVWC and Avon Water O&M Impact		Adjusted Increase/(Decrease)
Medical	$	1,878	$	1,375	$	503		$	29	$	474

The increase in O&M expenses excluding the incremental expense as a result of the acquisitions of HVWC and Avon Water, was approximately $1,540,000, or approximately 6.9%, in the six months endedJune 30, 2018 when compared to the same period in 2017.  The changes in individual items, excluding the impact of HVWC and Avon Water, are described below:

• Medical costs increased in the six months ended ending June 30, 2018 compared to the six months endedJune 30, 2017 primarily due to an increase in costs associated with claims filed by employees and their families and the costs associated with the administration of the Company’s medical plans;

• Payroll costs increased primarily due to more employee time being charged to capital projects in 2017 than in 2018, and therefore less time to O&M expense, and higher wages in the six months endedJune 30, 2018 compared to the six months endedJune 30, 2017;

• The increase in Outside services was primarily due to an increase in the use of non-merger related consultants and temporary labor during the six months endedJune 30, 2018 when compared to the same period in 2017, partially offset by a reduction in non-merger related legal costs;

• Utility costs increased in the period primarily due to an increase in electrical costs, partially offset by a decrease in fuel oil costs;

• Property and liability costs increased due to higher premiums on the Company’s insurance coverage stemming from the growth in insurable assets; and

• Customer costs increased primarily due to increased customer communications as well as an increase in uncollectible accounts. These increases were partially offset by a decrease in costs associated with a voluntary water conservation program that rewards customers for reducing their consumption by 10%.

36

The increases described above were partially offset by the following decreases to O&M expense:

• Other benefits decreased primarily due to lower costs associated with stock awards granted to certain named executives as well as an increase in capitalized benefits, which reduces O&M expense;

• Post-retirement medical costs decreased due to a regulatory asset established by the PURA that was fully depreciated during 2017; and

• Investor relations decreased due to lower costs associated with directors fees and a reduction in costs associated with the Company’s transfer agent.

The Company saw an approximate $1,389,000, or 18.1%, increase in its Depreciation expense from the six months endedJune 30, 2018 compared to the same period in 2017.  Of this increase, approximately $607,000 was attributable to the acquisitions of HVWC and Avon Water. The remaining increase was primarily due to higher Utility Plant in Service as of June 30, 2018 compared to June 30, 2017 driven by the completion of a large treatment plant in Connecticut in the second quarter of 2017 and continued spending on WICA and WISC projects in Connecticut and Maine, respectively.

The Company recorded an above-the-line Income Tax expense of $620,000 for the six months endedJune 30, 2018 compared to $814,000 of an above-the-line benefit in the same period of 2017. The primary reasons for the change in the six months endedJune 30, 2017 were discrete items including adjustments related to uncertain tax positions for the repair deduction in both Connecticut and Maine. Partially offsetting this increase was approximately $577,000 of Income Tax expense related to HVWC and Avon Water for the six months endedJune 30, 2018.

Other Income (Deductions), Net of Taxes decreased for the six months endedJune 30, 2018 by $5,478,000. The primary driver of this decrease was an increase in costs associated with the announced SJW merger. Additionally, the Company saw a decrease in AFUDC due to the completion of a large treatment plant in the second quarter of 2017. Partially offsetting these increase in Other Income (Deductions), the Company saw an increase in net income from the Company’s Service and Rentals segment during the six months endedJune 30, 2018.

Total Interest and Debt Expense increased by $1,521,000 in the six months endedJune 30, 2018 when compared to the same period in 2017. Of this increase, approximately $152,000 was attributable to the acquisition of Avon Water. The remaining increase was primarily due to higher debt balances outstanding and increased borrowing under our lines of credit at June 30, 2018 when compared to June 30, 2017.

Liquidity and Capital Resources

The Company is not aware of demands, events, or uncertainties that will result in a decrease of liquidity or a material change in the mix or relative cost of its capital resources, other than those outlined below.

Borrowing Facilities

As of June 30, 2018, the Company maintained a $15.0 million line of credit agreement with CoBank, that is currently scheduled to expire on July 1, 2020.  The Company maintained an additional line of credit of $45.0 million with Citizens Bank, N.A., with an expiration date of April 25, 2021.  Additionally, Avon Water maintains a $3.0 million line of credit with Northwest Community Bank, with an expiration date of September 30, 2018. As of June 30, 2018, the total lines of credit available to the Company were $63.0 million.  As of June 30, 2018 and December 31, 2017, the Company had $42.9 million and $19.3 million, respectively, of Interim Bank Loans Payable. As of June 30, 2018, the Company had $20.1 million in unused lines of credit.  Interest expense charged on lines of credit will fluctuate based on market interest rates.

On January 10, 2017, Maine Water executed and delivered to CoBank a new Promissory Note and Single Advance Term Loan Supplement, dated January 10, 2017 (the “Third Promissory Note”). On the terms and subject to the conditions set forth in the Third Promissory Note issued pursuant to the Company’s Master Loan Agreement, CoBank agreed to make an unsecured loan (the “Loan”) to Maine Water in the principal amount of $5,000,000 at 4.18%, due December 30, 2026. The proceeds of the Loan will be used to finance new capital expenditures and refinance existing debt owed to the Company, incurred in connection with general water system improvements.

On August 28, 2017, the Company executed and delivered to CoBank a new Promissory Note and Supplement (2017 Single Advance Term Loan) (the “2017 Promissory Note”). On the terms and subject to the conditions set forth in the 2017 Promissory Note issued pursuant to the Company’s Master Loan Agreement, CoBank agreed to make a term loan (the “Loan”) to the Company in the principal amount of $15,000,000. Under the 2017 Promissory Note, the Company will pay interest on the Loan at a fixed rate of 4.15% per year through August 20, 2037, the maturity date of the Loan.

37

On September 28, 2017, Connecticut Water completed the issuance of $35,000,000 aggregate principal amount of its 3.53% unsecured Senior Notes due September 25, 2037 (the “Senior Notes”). The Senior Notes were issued pursuant to the Note Purchase Agreement dated as of September 28, 2017 (the “Purchase Agreement”) between and among Connecticut Water, NYL Investors, LLC (“NY Life”), as agent, and the Purchasers listed in the Purchaser Schedule attached to the Purchase Agreement, in a private placement financing exempt from registration pursuant to Section 4(a)(2) of the Securities Act of 1933, as amended. The proceeds of the sale of the Senior Notes will be used by Connecticut Water to repay loans from the Company the proceeds of which were used for capital expenditure projects by Connecticut Water. The Senior Notes bear interest at the rate of 3.53% per annum, payable semi-annually on March 27 and September 27 of each year commencing on March 27, 2018. The principal amount of the Senior Notes, if not previously paid, shall be due on September 25, 2037. The Senior Notes are callable in whole or in part, subject to a make-whole amount.

During the first six months of 2018, the Company paid approximately $803,000 related to Connecticut Water Service’s 2017 CoBank issuance as well as the Company’s Term Note Payable issued as part of the 2012 acquisition of Maine Water, approximately $2,921,000 in sinking funds related to Maine Water’s outstanding bonds, approximately $82,000 in sinking funds related to HVWC’s bank loan and $96,000 related to Avon Water’s mortgage note payable.

Credit Rating

In January 2018, Standard & Poor’s Rating Services (“S&P”) affirmed its ‘A’ corporate credit rating on the Company. Additionally, S&P revised the Company’s ratings outlook as negative due to their view that the recently revised corporate tax code could potentially strain cash flows if our regulators determine a reduction in revenue requirements is appropriate and a potential weakening of consolidated financial measures due to our growth strategy and high capital spending requirements.

Stock Plans

The Company offers a dividend reinvestment and stock purchase plan (“DRIP”) for all registered shareholders and for the customers and employees of our regulated water companies, whereby participants can opt to have cash dividends directly reinvested into additional shares of the Company. In August 2011, the Board of Directors approved amendments to the DRIP (effective as of January 1, 2012) that permit the Company to add, at the Company’s discretion, an “up to 5.00% purchase price discount” feature to the DRIP which is intended to encourage greater shareholder, customer and employee participation in the DRIP. In August 2014, the Board of Directors approved further amendments to the DRIP to reflect the Company’s appointment of a new common stock transfer agent. On August 11, 2017, the Board of Directors approved a Third Amended and Restated DRIP which expanded the class of participants to include any persons other than registered shareholders, customers and employees described above, upon an initial minimum purchase of $500. The DRIP was also amended to add 129,000 additional shares to the DRIP’s share reserve and to revise certain monthly and quarterly share purchase requirements. During the six months endedJune 30, 2018 and 2017, plan participants invested $722,000 and $692,000, respectively, in additional shares as part of the DRIP.

2018 Construction Budget

The Board of Directors approved a $66.2 million construction budget for 2018, net of amounts to be financed by customer advances and contributions in aid of construction.  The Company will fund the capital budget through a combination of its internally generated funds, borrowing under its available lines of credit and potential new debt issuances by both Connecticut Water and Maine Water in 2018.

As the Company looks forward to the remainder of 2018 and 2019, it anticipates continued reinvestment to replace aging infrastructure and to seek recovery of these costs through periodic WICA and WISC applications.  The total cost of that investment may exceed the amount of internally generated funds.  The Company expects to rely upon its internally generated funds and short-term borrowing facilities and proceeds from a potential debt issuance during the remainder of 2018.

38

Commitments and Contingencies

The Company adopted the Internal Revenue Service (“IRS”) temporary tangible property regulations on the Company’s 2012 Federal tax return. Since that time, the Company has been recording a provision for any possible disallowance of a portion of the repair deduction if the Company’s Federal tax return were to be reviewed by the IRS. While the Company believes that the deductions taken on its tax returns are appropriate, the methodology for determining the deduction has not been agreed to by the taxing authorities.  During the Company’s review of the position through the quarter ended March 31, 2017, new information caused management to reassess the previously recorded provision. This reassessment resulted in the reversal of a portion of the provision related to the Maine subsidiary, in the amount of $1,164,000 in the first quarter of 2017. During the Company’s review of the position through the quarter ended June 30, 2017, the impact of the new information on the Connecticut subsidiary caused management to reassess the previously recorded provision. The reassessment resulted in the reversal of a portion of the provision in the amount of $2,445,000. Through June 30, 2017, the Company has recorded, as required by FASB ASC 740, a provision of $725,000 for a portion of the benefit that is not being returned to customers resulting from any possible tax authority challenge. For the six months endedJune 30, 2018, the Company recorded a provision of $530,000 for a portion of the benefit that is not being returned to customers resulting from any possible tax authority challenge. The Company had previously recorded a provision of $4.6 million in prior years for a cumulative total of $5.1 million.

The Company remains subject to examination by federal and state tax authorities for the 2014 through 2016 tax years. On April 26, 2017, Avon Water was notified by the IRS that its stand-alone Federal tax filing for 2015 was selected to be reviewed beginning in the second quarter of 2017 and the audit has since been expanded to include the 2016 standalone tax year. On March 20, 2018, Avon Water received a notice of adjustment from the IRS related to the Federal tax audit for the tax years ended December 31, 2015 and 2016. As a result, a reduction in the net operating loss carryover of $56,000 was recorded during the six months ended June 30, 2018.

There were no material changes under this subheading to any of the other items previously disclosed by the Company in its Annual Report on Form 10-K for the year December 31, 2017.

Part I, Item 3:  Quantitative and Qualitative Disclosure About Market Risk

The primary market risk faced by the Company is interest rate risk.  The Company has no exposure to derivative financial instruments or financial instruments with significant credit risk or off-balance-sheet risks.  In addition, the Company is not subject, in any material respect, to any currency or other commodity risk.

The Company is subject to the risk of fluctuating interest rates in the normal course of business.  The Company’s exposure to interest fluctuations is managed at the Company and subsidiary operations levels through the use of a combination of fixed rate long-term debt, variable long-term debt and short-term variable borrowings under financing arrangements entered into by the Company and its subsidiaries.  As of June 30, 2018, the Company had $63.0 million of variable rate lines of credit with two banks, under which the Company had $42.9 million of interim bank loans payable at June 30, 2018.

As of June 30, 2018, the Company had $22.05 million of variable-rate long-term debt outstanding.  Holding other variables constant, including levels of indebtedness, a one-percentage point change in interest rates would impact pre-tax earnings by approximately $0.2 million, annually.  The Company monitors its exposure to variable rate debt and will make future financing decisions as the need arises.

Part I, Item 4:  Controls and Procedures

Evaluation of Disclosure Controls and Procedures

As of June 30, 2018, management, including the Company’s Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the design and operation of the Company’s disclosure controls and procedures (as defined in Exchange Act Rule 13a-15(e)).  Based upon, and as of the date of that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures were effective.

Changes in Internal Control Over Financial Reporting

During the quarter ended June 30, 2018, there have been no changes in internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Part II, Item 1:  Legal Proceedings

On June 14, 2018, certain shareholders of the Company filed two nearly identical class-action complaints in the Connecticut Superior Court in the Judicial District of Middlesex against the Board of Directors, SJW, and Eric W. Thornburg, Chairman, President and Chief Executive Officer of SJW. The complaints allege that the Board of Directors breached its fiduciary duties in connection with negotiating the Merger and that SJW and Mr. Thornburg aided and abetted such breaches. Among other remedies, the actions seek to recover rescissory and other damages and attorney’s fees and costs. The Company believes the claims in these complaints are without merit and intends to vigorously defend this litigation. At this time, the Company cannot determine the likelihood that liability exists on the part of the Company and we are unable to provide a reasonable estimate of potential loss, if any.

We are involved in various other legal proceedings from time to time.  Although the results of legal proceedings cannot be predicted with certainty, there are no pending legal proceedings to which we or any of our subsidiaries are a party or to which any of our properties is the subject that presents a reasonable likelihood of a material adverse impact on the Company.

Part II, Item 1A: Risk Factors

Except as set forth in the below risk factors, information about the material risks related to our business, financial condition and results of operations for the three months ended June 30, 2018 does not materially differ from that set out under Part I, Item 1A “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2017. You should carefully consider the risk factors and other information discussed in our Annual Report on Form 10-K for the year ended December 31, 2017, as well as the information provided elsewhere in this report. Additional risks, uncertainties and other factors not presently known to us or that we currently deem immaterial may also impair the Company’s business operations, financial condition or operating results.

We may fail to consummate the Merger, and uncertainties related to the consummation of the Merger may have a material adverse effect on our business, results of operations and financial condition and negatively impact the price of our common stock.

As previously discussed, on August 5, 2018, the Company entered into the Revised Merger Agreement with SJW and Merger Sub, a direct wholly owned subsidiary of SJW. Pursuant to the Revised Merger Agreement, Merger Sub will merge with and into the Company, with the Company surviving the Merger as a wholly owned subsidiary of SJW. Subject to the terms and conditions of the Revised Merger Agreement, at the effective time of the Merger, each outstanding share of our common stock (other than certain cancelled shares) will be automatically converted into the right to receive an amount in cash equal to $70.00 per share, payable without interest. The Merger is subject to the satisfaction of a number of conditions beyond our control, including approval of the Revised Merger Agreement by the Company’s shareholders, regulatory approvals (including, without limitation, the approval of PURA and MPUC) and other customary closing conditions. The CPUC previously instituted an investigation into whether the Merger is subject to its approval and the Merger’s anticipated impacts in California. The CPUC is planning to complete its inquiry in time to allow the acquisition to go forward, if appropriate, by the end of 2018; however, there can be no assurance that the CPUC will not determine that its prior authorization is required for the Merger. There also is no assurance that the Merger and the other transactions contemplated by the Revised Merger Agreement will occur on the terms and timeline currently contemplated or at all. The conditions to the Merger could prevent or delay the completion of the Merger. In addition, the efforts to satisfy the closing conditions of the Merger, including the shareholder approval process (especially in light of the actions taken by Eversource Energy to solicit proxies from the Company’s shareholders in opposition to the Merger, as further discussed below) and the regulatory approval process, may place a significant burden on management and internal resources, and the Merger and related transactions, whether or not consummated, may result in a diversion of management’s attention from day-to-day operations and a disruption of our operations. Any significant diversion of management’s attention away from ongoing business and any difficulties encountered in the Merger process could have a material adverse effect on our business, results of operations and financial condition.

The Revised Merger Agreement also contains certain customary termination rights, including the right for each of the Company and SJW to terminate the Revised Merger Agreement if the Merger is not consummated by May 5, 2018, subject to two automatic three-month extensions up to November 5, 2019 if needed to satisfy the regulatory approvals. Upon termination of the Revised Merger Agreement under specified circumstances, including a change in the recommendation of the Board of Directors, the termination by the Company in order to accept a superior proposal with respect to an alternative transaction, or, in certain circumstances, as a result of a material breach of the Company’s non-solicitation obligations, the Company will be required to pay SJW a cash termination fee of $28.1 million. The Company may not be able to obtain the approval of its shareholders required to consummate the Merger, including in particular because some of the Company’s shareholders may be persuaded to vote against approval of the Revised Merger Agreement as a result of Eversource Energy’s actions to solicit proxies from the Company’s shareholders in opposition to the Merger, as further discussed below. If the Company’s shareholders fail to approve the Merger, then the Revised Merger Agreement will be terminated and the Company will be required to reimburse SJW’s expenses up to $5 million and may also be required to pay to SJW the termination fee of $28.1 million (less the amount of expenses reimbursed) in certain circumstances. If the proposed Merger is not completed or the Revised Merger Agreement is terminated, the price of our common stock may decline, including to the extent that the current market price of our common stock reflects an assumption that the Merger and the other transactions contemplated by the Revised Merger Agreement will be consummated without unexpected delays, which could have a material adverse effect on our business, results of operations and financial condition.

We are subject to various uncertainties and restrictions on the conduct of our business while the Merger is pending, which could have a material adverse effect on our business, results of operations and financial condition.

Uncertainty about the effect of the Merger on employees, customers, vendors, communities and other third parties who deal with us may have a material adverse effect on our business, results of operations and financial condition. These uncertainties may impair our ability to attract, retain and motivate key personnel pending the consummation of the Merger, as such personnel may experience uncertainty about their future roles following the consummation of the Merger. Additionally, these uncertainties could cause customers, vendors and other third parties who deal with us to seek to change existing business relationships with us or fail to extend an existing relationship with us, all of which could have a material adverse effect on our business, results of operations and financial condition. In addition, the Revised Merger Agreement restricts us from taking certain actions without SJW’s consent while the Merger is pending. These restrictions may, among other matters, prevent us from pursuing otherwise attractive business opportunities, buying or selling assets, making certain capital expenditures, refinancing or incurring additional indebtedness, entering into transactions or making other changes to our business prior to consummation of the Merger or termination of the Revised Merger Agreement. These restrictions and uncertainties could have a material adverse effect on our business, results of operations and financial condition.

42

We are subject to lawsuits relating to the Merger, which may impact the timing of the closing of the Merger and adversely impact our business.

On June 14, 2018, a putative class action complaint was filed against the members of the Board of Directors, SJW and Mr. Eric W. Thornburg (the chief executive officer and president of SJW) on behalf of the Company’s shareholders in the Connecticut Superior Court in the Judicial District of Middlesex under the caption Dunn v. Benoit, et al., Case No. MMX-CV18-6021536-S (Conn. Super. Ct.). The complaint alleges that the members of the Board of Directors breached their fiduciary duties owed to the Company’s shareholders in connection with negotiating the Merger. The complaint further alleges that SJW and Mr. Thornburg aided and abetted the alleged breaches by the Board of Directors. Among other remedies, the action seeks to recover rescissory and other damages and attorneys’ fees and costs. The defendants believe this lawsuit is without merit and intend to defend vigorously against these allegations.

Also on June 14, 2018, a near-identical putative class action complaint was filed against the members of the Board of Directors, SJW and Mr. Thornburg on behalf of the Company’s shareholders in the Connecticut Superior Court in the Judicial District of Middlesex under the caption Tillotson v. Benoit, et al., Case No. MMX-CV18-6021537-S (Conn. Super. Ct.). The complaint alleges that the members of the Board of Directors breached their fiduciary duties owed to the Company’s shareholders in connection with negotiating the Merger. The complaint further alleges that SJW and Mr. Thornburg aided and abetted the alleged breaches by the Board of Directors. Among other remedies, the action seeks to recover rescissory and other damages and attorneys’ fees and costs. The defendants believe this lawsuit is without merit and intend to defend vigorously against these allegations.

The Company and our directors and officers may be subject to lawsuits relating to the Merger, including, among other things, in relation to the change from stock consideration in the Original Merger Agreement to cash consideration in the Revised Merger Agreement. Litigation is very common in connection with the sale of public companies, regardless of whether the claims have any merit. One of the conditions to consummating the Merger is that no order preventing or otherwise prohibiting the consummation of the Merger shall have been issued by any court. Consequently, if any lawsuit challenging the Merger is successful in obtaining an order preventing the consummation of the Merger, that order may delay or prevent the Merger from being completed. While we will evaluate and defend against any lawsuits, the time and costs of defending against litigation relating to the Merger may adversely affect our business.

The Revised Merger Agreement contains provisions that could discourage a potential competing acquiror of the Company, or could result in any competing proposal being at a lower price than it might otherwise be. However, competing acquirors for the Company or SJW could negatively impact the completion and timing of the proposed transaction and cause disruption and expense for the Company.

Other than in connection with the 45-day go-shop period permitted by the First Amended and Restated Merger Agreement that concluded at 11:59 p.m. Eastern time on July 14, 2018, the Revised Merger Agreement contains “no shop” provisions that, subject to limited exceptions, restrict the Company’s ability to solicit, initiate, knowingly encourage or knowingly facilitate any takeover proposal (which includes among other things any proposal or offer made by a third party relating to any merger, amalgamation, consolidation, share exchange, other business combination, recapitalization, liquidation, dissolution or similar transaction involving the Company, or any of its subsidiaries, or any sale, lease, contribution or other disposition, directly or indirectly, of any business or assets of the Company, or any of its subsidiaries, representing 15% or more of the consolidated revenues, net income or assets of the Company, or any its subsidiaries, taken as a whole). In addition, SJW has an opportunity to offer to modify the terms of the Merger in response to any competing acquisition proposal before the Board of Directors may withdraw or qualify its recommendation with respect to the Merger.

These provisions could discourage a potential third-party acquiror that might have an interest in acquiring all or a significant portion of the Company from considering or proposing that acquisition, even if it were prepared to pay consideration with a higher per share cash or market value than the cash consideration proposed to be paid to the Company’s shareholders in the Merger or might result in a potential third-party acquiror proposing to pay a lower price to the shareholders than it might otherwise have proposed to pay because of the added expense of the $28.1 million termination fee for the Company, as applicable, that may become payable in certain circumstances.

On April 4, 2018, SJW received an unsolicited proposal from California Water Service Group (“Cal Water”) regarding the acquisition of all of the outstanding shares of SJW common stock for $68.25 per share. On April 5, 2018, the Company received an unsolicited proposal from Eversource Energy regarding the acquisition of all of the outstanding shares of our common stock for $63.50 per share in cash and/or stock at the election of holders of our common stock, which it revised to $64.00 per share in cash and/or stock at the election of holders of our common stock on July 2, 2018. While each of SJW and the Company has determined that the unsolicited proposal that it had received was neither a superior proposal nor reasonably

43

likely to lead to a superior proposal, Eversource Energy filed on April 27, 2018 a preliminary proxy statement to solicit proxies in opposition to the Merger and Cal Water filed a Schedule TO with the SEC commencing a tender offer to acquire all outstanding shares of SJW for $68.25 per share in cash on June 7, 2018, and it is unclear what additional actions these third parties may take to further their proposals. Even if ultimately unsuccessful, actions taken by these or other third parties, including the proxy contest, could disrupt the Company’s business, cause the Company to incur substantial additional expense, and negatively impact the ability of SJW and the Company to consummate the Merger and the expected timing of the consummation of the Merger. In addition, as a result of the proxy solicitation by Eversource Energy in opposition to the Merger, initiation of the Cal Water tender offer, and other actions that may be taken by these or other third parties, the Company’s shareholders may vote against the approval of the Merger and related proposals at the special meeting and, consequently, the required shareholder approval may not be obtained.

If the Revised Merger Agreement is terminated and the Company determines to seek another business combination, it may not be able to negotiate a transaction with another party on terms comparable to, or better than, the terms of the Merger.

Notes To Financial Statements [Abstract]

Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]

1. Basis of Preparation of Financials

The condensed consolidated financial statements included herein have been prepared by Connecticut Water Service, Inc. (“CTWS” or the “Company”) and its wholly-owned subsidiaries, pursuant to the rules and regulations of the Securities and Exchange Commission and reflect all adjustments that are of a normal recurring nature which are, in the opinion of management, necessary to a fair statement of the results for interim periods.  Certain information and footnote disclosures have been omitted pursuant to such rules and regulations, although the Company believes that the disclosures are adequate to make the information presented not misleading.  The Company’s primary operating subsidiaries are: The Connecticut Water Company (“Connecticut Water”), The Heritage Village Water Company (“HVWC”) and The Avon Water Company (“Avon Water”) in the State of Connecticut and The Maine Water Company (“Maine Water”) in the State of Maine. The Condensed Consolidated Balance Sheet at December 31, 2017 has been derived from the audited financial statements at that date but does not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements.  It is suggested that these condensed consolidated financial statements be read in conjunction with the financial statements and the notes thereto included in the Company’s latest Annual Report on Form 10-K for the fiscal year ended December 31, 2017 (the “10-K”) and as updated in the Company’s Quarterly Report on Form 10-Q for the period ended March 31, 2018.

The results for interim periods are not necessarily indicative of results to be expected for the year since the consolidated earnings are subject to seasonal factors.  Effective February 27, 2017 and July 1, 2017, the Company acquired HVWC and Avon Water, respectively, discussed further in Note 12 below.  As a result, the Company’s Condensed Consolidated Statements of Net Income, Condensed Consolidated Statements of Comprehensive Income, Condensed Consolidated Statements of Retained Earnings and Condensed Consolidated Statements of Cash Flows for the three and six months endedJune 30, 2017 do not include Avon Water, however, they do include the approximate four months of activity related to HVWC after its acquisition on February 27, 2017.  The Condensed Consolidated Statements of Net Income, Condensed Consolidated Statements of Comprehensive Income, Condensed Consolidated Statements Retained Earnings and the Condensed Consolidated Statements of Cash Flows for the three and six months endedJune 30, 2018 include HVWC’s and Avon Water’s results. HVWC’s and Avon Water’s assets and liabilities are included in the Condensed Consolidated Balance Sheet as of June 30, 2018 and December 31, 2017.

As noted in Note 12 below, HVWC serves approximately 4,700 water customers in the Towns of Southbury, Middlebury, and Oxford, Connecticut and approximately 3,000 wastewater customers in the Town of Southbury, Connecticut. The results of the wastewater line of business are included in the Company’s Water Operations segment. Additionally, as noted in Note 12, Avon Water serves approximately 4,800 water customers in the Towns of Avon, Farmington, and Simsbury, Connecticut.

Proposed Merger with SJW Group

On August 5, 2018, the Company entered into a Second Amended and Restated Agreement and Plan of Merger (the “Revised Merger Agreement”) with SJW Group, a Delaware corporation (“SJW”), and Hydro Sub, Inc., a Connecticut corporation and a direct wholly owned subsidiary of SJW (“Merger Sub”), pursuant to which Merger Sub will merge with and into the Company, with the Company surviving the Merger as a wholly owned subsidiary of SJW (the “Merger”). Subject to the terms and conditions of the Revised Merger Agreement, at the effective time of the Merger, each outstanding share of our common stock (other than certain cancelled shares) will be automatically converted into the right to receive an amount in cash equal to $70.00 per share, payable without interest. The Revised Merger Agreement amends and restates in its entirety the Amended and Restated Agreement and Plan of Merger (the “First Amended and Restated Merger Agreement”), dated as of May 30, 2018, by and among the Company, SJW and Merger Sub, which amended and restated in its entirety the Agreement and Plan of Merger (the “Original Merger Agreement”), dated as of March 14, 2018, by and among the Company, SJW and Merger Sub.

The Board of Directors approved, adopted and declared advisable and resolved to recommend to the Company’s shareholders the approval of the Revised Merger Agreement and the Merger following a comprehensive review of the transaction.

The Merger is subject to certain customary closing conditions, including, among other things, approval of the Revised Merger Agreement by the Company’s shareholders and regulatory approvals (including the approval of the Connecticut Public Utilities Regulatory Authority (“PURA”) and the Maine Public Utilities Commission (“MPUC”) and pre-approvals of any license transfers from the Federal Communications Commission). The required waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and the rules and regulations promulgated thereunder (the “HSR Act”), was terminated early on April 27, 2018.

On May 4, 2018, Maine Water filed with the MPUC an application for approval of the Merger. On May 7, 2018, the Company and SJW filed with the PURA a joint application for approval of the Merger. Following the start on May 31, 2018 of a 45-day go-shop process permitted by the First Amended and Restated Merger Agreement, the Company and SJW withdrew their joint application on June 19, 2018, and filed a new joint application on July 18, 2018, following the end of the go-shop process.

On July 20, 2018, the California Public Utilities Commission (“CPUC”) formally issued an Order Instituting Investigation (“Order”) providing that the CPUC will investigate whether the Merger is subject to CPUC approval and the Merger’s anticipated impacts within California. The Order states that the CPUC plans to substantially complete its investigation in a manner sufficiently timely to allow the Merger to go forward by the end of 2018, if appropriate.

The Company and SJW expect the closing of the Merger to occur during the first quarter of 2019.

Regulatory Matters

The rates we charge our water and waste water customers in Connecticut and Maine are established under the jurisdiction of and are approved by PURA and the MPUC, respectively. It is our policy to seek rate relief as necessary to enable us to achieve an adequate rate of return. The Regulated Companies’ allowed returns on equity and allowed returns on rate base are as follows:

As of June 30, 2018	Allowed Return on Equity		Allowed Return on Rate Base
Connecticut Water	9.75	%	7.32	%
HVWC (blended water and wastewater rates)	10.10	%	7.19	%
Avon Water	10.00	%	7.79	%
Maine Water	9.50	%	7.96	%

The PURA establishes rates in Connecticut on a company-wide basis while the MPUC approves Maine Water’s rates on a division-by-division basis. Each of Connecticut Water, HVWC, Avon Water and Maine Water are allowed to add surcharges to customers’ bills in order to recover certain costs associated with approved capital projects in between full rate cases, as well as approved surcharges for Water Revenue Adjustments, in Connecticut, as discussed in more detail below. HVWC has not added surcharges to customers’ bills in order to recover certain approved capital projects as of June 30, 2018, however, HVWC, as ordered by PURA, began to utilize Water Revenue Adjustments as of March 31, 2017.

On January 3, 2018, PURA filed a motion to reopen the most recent rate case decisions for the Company’s Connecticut Regulated Companies to determine what, if any, adjustments to rates are appropriate to account for revisions to tax laws, including corporate tax rates, contained in the Tax Cuts and Jobs Act (“Tax Act”). PURA held a hearing on July 30, 2018 for regulated water companies. As discussed below, Connecticut Water has entered into a settlement agreement with the Connecticut Office of Consumer Counsel (“OCC”) that covers treatment of the Tax Act.

On January 11, 2018, the MPUC issued a notice of investigation to determine the impact of the Tax Act on Maine Water. The investigation will allow the MPUC to determine the specific impact of the Tax Act and whether any rate adjustments are warranted. Following discovery, technical conferences were held on April 19, 2018 and July 17, 2018. The current schedule for the investigation anticipates a report by the Hearing Examiner on August 13, 2018. In addition to determining the impact of the Tax Act on the justness and reasonableness of Maine Water’s rates, the MPUC will consider whether to issue an accounting order to establish a regulatory liability which defers for future flow-through to ratepayers the impact of the tax changes.

Maine Water Land Sale

On March 11, 2016, Maine Water entered into a purchase and sale agreement with the Coastal Mountains Land Trust, a Maine nonprofit corporation (the “Land Trust”) pursuant to which Maine Water agreed to sell two conservation easements to the Land Trust on approximately 1,300 acres of land located in the towns of Rockport, Camden and Hope, in Knox County, Maine valued in the aggregate at $3.1 million.  The land had a book value of approximately $600,000 at June 30, 2018 and December 31, 2017 and is included in “Utility Plant” on the Company’s Consolidated Balance Sheets. The easements and purchase prices are as follows:

1.Ragged Mountain Mirror Lake Conservation Easement: $1,875,000; and

2.Grassy Pond conservation Easement: $600,000.

On June 25, 2018, an amendment to the agreement was made to extend closing of the first transaction to September 30, 2018, from June 30, 2018.  This is also expected to extend the second closing into 2020.  Maine Water will make a $250,000 contribution to the Land Trust upon completion of the closing of the first easement sale.  Maine Water also expects to claim a charitable deduction for the $600,000 in excess of the fair market value of the second easement over the $600,000 sale price.

Connecticut Rates

Connecticut Water’s Water Infrastructure Conservation Adjustment (“WICA”) was 9.98% and 8.25% at June 30, 2018 and 2017, respectively. As of June 30, 2018, Avon Water’s WICA surcharge was 7.51%. As of June 30, 2018, HVWC has not filed for a WICA surcharge.

On February 6, 2018, Connecticut Water filed a petition with PURA to reopen Connecticut Water’s 2010 rate case proceeding (previously reopened in 2013) for the limited purpose of approving a Settlement Agreement entered into by Connecticut Water and the OCC (the “Agreement”). The Agreement proposes a change in Connecticut Water’s customer rates effective for bills rendered on and after April 1, 2018 made up of the following two components: (1) the revenue requirements associated with a $36.3 million addition to rate base to reflect necessary upgrades to Connecticut Water’s Rockville Water Treatment Plant; and (2) the folding in to base rates of the Company’s present WICA surcharges. In addition, the Agreement provides that:

1. Upon implementation of new rates under the Agreement, until such time as new rates are adopted in a general rate case, through a temporary modification of the earnings sharing mechanism, Connecticut Water customers will receive one hundred percent of any earnings in excess of levels allowed by law rather than limiting such customer credits to 50% as contemplated by applicable law;

2. Connecticut Water agrees it will not file for a general increase of Connecticut Water’s base rates to be effective before January 1, 2020;

3. The pending proceeding initiated by PURA in Docket No. 09-12-11RE03, Application of The Connecticut Water Company for Amended Rates – Federal Tax Cuts and Jobs Act shall be closed; and

4. Connecticut Water shall continue to make investments in infrastructure replacement consistent with its approved WICA plan. Connecticut Water shall be allowed to continue to pursue recovery of eligible projects through WICA.

The Agreement provides that, if PURA does not fully approve the Agreement in its entirety, it shall be deemed withdrawn.  Accordingly, the Agreement has no operative effect unless and until it is approved by PURA.  No assurance can be given that PURA will approve the Agreement and permit some or all of the terms contained in the Agreement requested by the parties.  PURA has agreed to the request to reopen the rate proceeding.  PURA issued a Proposed Final Decision on July 6, 2018 that rejected the Settlement Agreement, due to the proposed treatment of income tax expense resulting from the Tax Act. The Company and the Office of Consumer Council each filed written exceptions to the draft decision and a hearing was held on a revised settlement agreement submitted from both parties that would include an adjustment to reflect the impacts of the Tax Act but at a lower dollar amount than recommended in the PURA draft decision.  A final decision is anticipated from PURA in August with implementation of new rates to immediately follow.

Since 2013, Connecticut law has authorized a Water Revenue Adjustment (“WRA”) to reconcile actual water revenues with the revenues projected in the last general rate case and allows companies to adjust rates as necessary to recover the revenues approved by PURA in the last 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. Additionally, projects eligible for WICA surcharges were expanded to include energy conservation projects, improvements required to comply with streamflow regulations, and improvements to certain acquired systems.

Connecticut Water’s and HVWC’s allowed revenues for the six months endedJune 30, 2018, as approved by PURA during each company’s most recent general rate case and including subsequently approved WICA surcharges, are approximately $38.7 million. Through normal billing for the six months endedJune 30, 2018, revenue for Connecticut Water and HVWC would have been approximately $35.2 million had the WRA not been implemented. As a result of the implementation of the WRA, Connecticut Water and HVWC recorded $3.5 million in additional revenue for the six months endedJune 30, 2018. Avon Water does not currently use the WRA mechanism. Avon Water does not currently have PURA approval to apply the WRA surcharge to their customers’ bills.

Maine Rates

In Maine, the overall, cumulative Water Infrastructure Charge (“WISC”) for all divisions was 6.8% and 5.7% as of June 30, 2018 and 2017, respectively. The WISC rates for the Biddeford and Saco division were reset to zero with the approval of the general rate increase discussed below.

On June 29, 2017, Maine Water filed for a rate increase in its Biddeford and Saco division. The rate request was for an approximate $1.6 million, or 25.1%, increase in revenues. The rate request is designed to recover higher operating expenses, depreciation and property taxes since Biddeford and Saco’s last rate increase in 2015. Maine Water and the Maine Office of the Public Advocate reached an agreement that increases annual revenue by $1.56 million. The agreement was approved by the MPUC on December 5, 2017, with new rates effective December 1, 2017.

A water revenue adjustment mechanism law in Maine became available to regulated water utilities in Maine on October 15, 2015. Maine Water is currently precluded from seeking new rates in the Biddeford and Saco division due to provisions in the settlement agreement with the MPUC. As the stay-out periods for other divisions expire, Maine Water expects to request usage of this mechanism as Maine Water file rate cases for those divisions.

New Accounting Pronouncements

6 Months Ended

Notes To Financial Statements [Abstract]

Recently Adopted and New Accounting Pronouncements

4. Recently Adopted and New Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers,” (“ASU No. 2014-09”) which amended its guidance related to revenue recognition. ASU No. 2014-09 requires an entity to recognize revenue as performance obligations are met, in order to reflect the transfer of promised goods or services to customers in an amount that reflects the consideration the entity is entitled to receive for those goods or services. The following steps are applied in the updated guidance: (1) identify the contract(s) with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when, or as, the entity satisfies a performance obligation. ASU No. 2014-09 became effective for public companies for fiscal years, and interim periods within those years, beginning after December 15, 2016, and could be adopted either retrospectively to each prior reporting period presented or as a cumulative-effect adjustment as of the date of adoption, however early adoption is not permitted. On April 1, 2015, the FASB voted for a one-year deferral of the effective date of ASU No. 2014-09, making ASU No. 2014-09 effective for public companies for fiscal years, and interim periods within those years, beginning after December 15, 2017. The Company engaged in a project to analyze the impact that adoption of this standard would have on our consolidated financial statements, disclosures, and internal controls. The project included identification of the Company’s revenue streams, creation of an inventory of its contracts with customers, evaluation of a representative sample of these contracts with respect to the new guidance and documentation of any required changes in reporting. The Company derives more than 90% of its revenue from regulated delivery of water and wastewater services to its retail customers, which is considered a contract with customers under ASU 2014-09, excluding revenue recognized as WRA. The majority of the remainder of the Company’s revenue is derived from contract operations and unregulated revenues generated from its Linebacker^® program, also considered a contract with customers under ASU 2014-09. The Company determined that revenue generated from the attachment of telecommunications equipment to its facilities through leases with third parties is outside the scope of ASU No. 2014-09. In 2017, the American Institute of Certified Public Accountants (AICPA) power and utility entities revenue recognition task force determined that contributions in aid of construction are not in the scope of ASU No. 2014-09. The Company’s adoption of ASU No. 2014-09 on January 1, 2018 did not result in any change in the measurement and timing of recognition of its revenues. The Company used the modified retrospective approach when implementing ASU No. 2014-09. See Note 5 for more details.

In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842)”, (“ASU No. 2016-02”), which will require lessees to recognize the following for all leases at the commencement date of a lease: a) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and b) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Public business entities should apply the amendments in ASU No. 2016-02 for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application is permitted for all public business entities and all nonpublic business entities upon issuance. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Lessees and lessors may not apply a full retrospective transition approach. The Company is currently assessing the impact of this standard on its consolidated financial statements and footnote disclosures, but does not expect that the adoption of this guidance will materially impact our consolidated financial position.

In August 2016, the FASB issued ASU No. 2016-15, “Classification of Certain Cash Receipts and Cash Payments” (“ASU No. 2016-15”). The amendments ASU No. 2016-15 clarify the classification for eight different types of activities, including debt prepayment and extinguishment costs, proceeds from insurance claims and distributions from equity method investees. For public business entities, ASU No. 2016-15 is effective for financial statements issued for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. The Company’s adoption of this guidance did not materially impact our consolidated financial position or cash flows.

In March 2017, the FASB issued ASU 2017-07, "Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost," (“ASU 2017-07”) which amends the requirements related to the income statement presentation of the components of net periodic benefit cost for employer sponsored defined benefit pension and other postretirement benefit plans. Under ASU 2017-07, an entity must disaggregate and present the service cost component of net periodic benefit cost in the same income statement line item as other employee compensation costs arising from services rendered during the period, and only the service cost component will be eligible for capitalization. Other components of net periodic benefit cost will be presented separately from the line item that includes the service cost. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. Early adoption is permitted at the beginning of an annual period in which the financial statements have not been issued. Entities must use a retrospective transition method to adopt the requirement for separate presentation of the income statement service cost and other components, and a prospective transition method to adopt the requirement to limit the capitalization of benefit cost to the service component. As a result of the adoption of ASU 2017-07 in the first quarter of 2018, the Company reclassified $210,000 and $443,000 out of Operation and Maintenance expense and moved it to the “Other” line item in the “Other (Deductions) Income, Net of Taxes” section of the quarter to date and year to date, respectively, June 30, 2017 Condensed Consolidated Statement of Income to conform with the requirements of 2017-07.

In February 2018, the FASB issued ASU 2018-02, “Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income”, (ASU No. 2018-02) to help businesses and other organizations present some effects from the Tax Act’s reduction in the corporate tax rate in their income statements. ASU No. 2018-02 gives the option of reclassifying what are called the “stranded” tax effects within accumulated other comprehensive income to retained earnings during each fiscal year or quarter in which the effect of the lower tax rate is recorded. ASU No. 2018-02 instructs businesses and other organizations to provide a disclosure in their financial statement footnotes that describes the accounting policy they used to release the income tax effects from accumulated other comprehensive income, whether they are reclassifying the stranded income tax effects from the Tax Cut and Jobs Act, and information about the other effects on taxes from the reclassification. ASU 2018-02 is effective for all organizations for fiscal years that begin after December 15, 2018, and the quarterly and other interim periods in those years, with early adoption permissible. The Company adopted ASU No. 2018-02 effective December 31, 2017. The adoption of ASU No. 2018-02 resulted in an approximate $70,000 increase to Retained Earnings at December 31, 2017.

There are no mandatory sinking fund payments required on Connecticut Water’s outstanding bonds.  However, certain fixed rate Unsecured Water Facilities Revenue Refinancing Bonds provide for an estate redemption right whereby the estate of deceased bondholders or surviving joint owners may submit bonds to the trustee for redemption at par, subject to a $25,000 per individual holder and a 3% annual aggregate limitation.

On January 10, 2017, Maine Water executed and delivered to CoBank a new Promissory Note and Single Advance Term Loan Supplement, dated January 10, 2017 (the “Third Promissory Note”). On the terms and subject to the conditions set forth in the Third Promissory Note issued pursuant to the Agreement, CoBank agreed to make an unsecured loan (the “Loan”) to Maine Water in the principal amount of $5,000,000 at 4.18%, due December 30, 2026.

Fair Value Disclosures

Fair Value Disclosures

FASB Accounting Standards Codification (“ASC”) 820, Fair Value Measurements and Disclosures (“FASB ASC 820”) provides enhanced guidance for using fair value to measure assets and liabilities and expands disclosure with respect to fair value measurements.

FASB ASC 820 establishes a fair value hierarchy that distinguishes between assumptions based on market data (observable inputs) and the Company’s assumptions (unobservable inputs).  The hierarchy consists of three broad levels, as follows:

Level 1 – Quoted market prices in active markets for identical assets or liabilities.

Level 2 – Inputs other than Level 1 that are either directly or indirectly observable.

Level 3 – Unobservable inputs developed using the Company’s estimates and assumptions, which reflect those that the Company believes market participants would use.

The following table summarizes our financial instruments measured at fair value on a recurring basis within the fair value hierarchy as of June 30, 2018 (in thousands):

	Level 1		Level 2		Level 3		Total
Asset Type:
Money Market Fund	$	70	$	—	$	—	$	70
Mutual Funds:
Equity Funds (1)	2,007		—		—		2,007
Fixed Income Funds (2)	639		—		—		639
Total	$	2,716	$	—	$	—	$	2,716

The following table summarizes our financial instruments measured at fair value on a recurring basis within the fair value hierarchy as of December 31, 2017 (in thousands):

	Level 1		Level 2		Level 3		Total
Asset Type:
Money Market Fund	$	70	$	—	$	—	$	70
Mutual Funds:
Equity Funds (1)	2,051		—		—		2,051
Fixed Income Funds (2)	642		—		—		642
Total	$	2,763	$	—	$	—	$	2,763

(1) Mutual funds consist primarily of equity securities and are presented on the Other Property and Investments line item of the Company’s Condensed Consolidated Balance Sheets.

(2) Mutual funds consist primarily of fixed income securities and are presented on the Other Property and Investments line item of the Company’s Condensed Consolidated Balance Sheets.

The following methods and assumptions were used to estimate the fair value of each of the following financial instruments, which are not recorded at fair value on the financial statements.

Cash and cash equivalents – Cash equivalents consist of highly liquid instruments with original maturities at the time of purchase of three months or less.  The carrying amount approximates fair value.  Under the fair value hierarchy the fair value of cash and cash equivalents is classified as a Level 1 measurement.

Company Owned Life Insurance – The fair value of Company Owned Life Insurance is based on the cash surrender value of the contracts. These contracts are based principally on a referenced pool of investment funds that actively redeem shares and are observable and measurable and are presented on the “Other Property and Investments” line item of the Company’s Consolidated Balance Sheets. The value of Company Owned Life Insurance at June 30, 2018 and December 31, 2017 was $4,098,000 and $4,018,000, respectively.

Long-Term Debt – The fair value of the Company’s fixed rate long-term debt is based upon borrowing rates currently available to the Company.  As of June 30, 2018 and December 31, 2017, the estimated fair value of the Company’s long-term debt was $258,051,000 and $268,628,000, respectively, as compared to the carrying amounts of $256,357,000 and $258,272,000, respectively. The estimated fair value of long term debt was calculated using a discounted cash flow model that uses comparable interest rates and yield curve data based on the A-rated MMD (Municipal Market Data) Index which is a benchmark of current municipal bond yields. Under the fair value hierarchy, the fair value of long term debt is classified as a Level 2 measurement.

Advances for Construction – Customer advances for construction had a carrying amount of $19,560,000 and $20,024,000 at June 30, 2018 and December 31, 2017, respectively. Their relative fair values cannot be accurately estimated since future refund payments depend on several variables, including new customer connections, customer consumption levels and future rate increases.

The fair values shown above have been reported to meet the disclosure requirements of FASB ASC 825, “Financial Instruments” (“FASB ASC 825”) and do not purport to represent the amounts at which those obligations would be settled.

Income Taxes

Income Taxes

FASB ASC 740 Income Taxes (“FASB ASC 740”) addresses the determination of how tax benefits claimed or expected to be claimed on a tax return should be recorded in the financial statements. Under FASB ASC 740, the Company must recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate resolution.

The Company adopted the Internal Revenue Service (“IRS”) temporary tangible property regulations on the Company’s 2012 Federal tax return. Since that time, the Company has been recording a provision for any possible disallowance of a portion of the repair deduction if the Company’s Federal tax return were to be reviewed by the IRS. While the Company believes that the deductions taken on its tax returns are appropriate, the methodology for determining the deduction has not been agreed to by the taxing authorities.  During the Company’s review of the position through the quarter ended March 31, 2017, new information caused management to reassess the previously recorded provision. This reassessment resulted in the reversal of a portion of the provision related to the Maine subsidiary, in the amount of $1,164,000 in the first quarter of 2017. During the Company’s review of the position through the quarter ended June 30, 2017, the impact of the new information on the Connecticut subsidiary caused management to reassess the previously recorded provision. The reassessment resulted in the reversal of a portion of the provision in the amount of $2,445,000. Through June 30, 2017, the Company has recorded, as required by FASB ASC 740, a provision of $725,000 for a portion of the benefit that is not being returned to customers resulting from any possible tax authority challenge. For the six months endedJune 30, 2018, the Company recorded a provision of $530,000 for a portion of the benefit that is not being returned to customers resulting from any possible tax authority challenge. The Company had previously recorded a provision of $4.6 million in prior years for a cumulative total of $5.1 million.

On December 22, 2017, H.R. 1, originally known as the Tax Cuts and Jobs Act, (the “Tax Act”) was enacted. Among the significant changes to the U.S. Internal Revenue Code, the Tax Act lowered the U.S. federal corporate income tax rate (“Federal Tax Rate”) from 35% to 21% effective January 1, 2018. In December 2017, the Securities and Exchange Commission staff issued Staff Accounting Bulletin No. 118, which addresses how a company recognizes provisional amounts when a company does not have the necessary information available, prepared or analyzed (including computations) in reasonable detail to complete its accounting for the effect of the changes in the Tax Act. The measurement period ends when a company has obtained, prepared and analyzed the information necessary to finalize its accounting, but cannot extend beyond one year. While we are able to make reasonable estimates of the impact of the reduction in corporate rate, the final impact of the Tax Act may differ from these estimates, due to, among other things, changes in our interpretations and assumptions, additional guidance that may be issued by the I.R.S., and actions we may take. We are continuing to gather additional information to determine the final impact. Provisional amounts have been recorded as a Regulatory Liability to the extent that the tax savings over time will be returned to customers in utility rates, and a non-cash adjustment was recognized to record additional income tax expense to the extent revalued deferred income taxes are not believed to be recoverable in utility customer rates. Accounting for the income tax effects of the Tax Act is expected to be completed when a decision is reached by both PURA and the MPUC regarding the impact that shall be included in utility customer rates. During the first half of 2018, the Company performed further analysis on the impact of the enacted legislation.  Through the quarter ended June 30, 2018, the Company recorded an excess accumulated deferred tax liability of $31 million, of which $28 million relates to the Tax Act.  The additional analysis resulted in no change to the Unrecovered Income Taxes and Unfunded Future Income Taxes or income tax expense.

From time to time, the Company may be assessed interest and penalties by taxing authorities.  In those cases, the charges would appear on the Other line item within the Other Income (Deductions), Net of Taxes section of the Company’s Condensed Consolidated Statements of Income.  There were no such charges for the six months endedJune 30, 2018 and 2017.  Additionally, there were no accruals relating to interest or penalties as of June 30, 2018 and December 31, 2017.  The Company remains subject to examination by federal and state tax authorities for the 2014 through 2016 tax years. On April 26, 2017, Avon Water was notified by the IRS that its stand-alone Federal tax filing for 2015 was selected to be reviewed beginning in the second quarter of 2017 and the audit was expanded to include the 2016 standalone tax year. On March 20, 2018, Avon Water received a notice of adjustment from the IRS related to the Federal tax audit for the tax years ended December 31, 2015 and 2016. As a result, a reduction in the net operating loss carryover of $56,000 was recorded during the six months ended June 30, 2018.

The Company is currently engaged in an analysis to determine the amount of expenditures related to tangible property that will be reflected on its 2018 Federal Tax Return to be filed in September 2019.  As a result, through the second quarter of 2018, the Company has estimated the portion of its infrastructure investment that will qualify as a repair deduction for 2018 and has reflected that deduction in its effective tax rate, net of any reserves.  Consistent with other differences between book and tax expenditures, the Company is required to use the flow-through method to account for any timing differences not required by the IRS to be normalized.

The Company’s effective income tax rate for the three months endedJune 30, 2018 and 2017 was 10.7% and (10.5)%, respectively. The Company’s effective tax rate, excluding discrete items recorded during the three months endedJune 30, 2018 and 2017, was (6.8)% and 16.2%, respectively. In 2018, these discrete items include adjustments related to uncertain tax positions for the repair deduction in Connecticut and purchase accounting adjustments to goodwill. In 2017, these discrete items include adjustments related to uncertain tax positions for the repair deduction in Connecticut. Excluding discrete items, there was a decrease in the effective tax rate year over year for the three month period of approximately 23%. The decrease in the effective tax rate for this period can be attributed to a higher estimated repair deduction, higher tax deductible pension contribution and higher performance stock deduction in 2018 than in 2017. The Company’s effective income tax rate for the six months endedJune 30, 2018 and 2017 was 11.7% and (7.1)%, respectively. The Company’s effective tax rate, excluding discrete items recorded during the six months endedJune 30, 2018 and 2017, was (18.0)% and 17.7%, respectively. In 2018, these discrete items include adjustments related to uncertain tax positions for the repair deduction in Connecticut, purchase accounting adjustments to goodwill, an IRS audit adjustment, and adjustments required under the Tax Act. In 2017, these discrete items include adjustments related to uncertain tax positions for the repair deduction in Connecticut. Excluding discrete items, there was a decrease in the effective tax rate year over year for the six month period of approximately 36%. The decrease in the effective tax rate for this period can be attributed to a higher estimated repair deduction, higher tax deductible pension contribution and higher performance stock deduction in 2018 than in 2017. The blended Federal and State statutory income tax rates during the three and six months endedJune 30, 2018 and 2017 were 28% and 41%, respectively. In determining its annual estimated effective tax rate for interim periods, the Company reflects its estimated permanent and flow-through tax differences for the taxable year, including the basis difference for the adoption of the tangible property regulations.

The Heritage Village Water Company Acquisition

On May 10, 2016, the Company announced that it had reached an agreement to acquire HVWC, pending a vote of HVWC shareholders, approval by PURA and MPUC and the satisfaction of other various closing conditions, pursuant to the terms of Agreement and Plan of Merger dated May 10, 2016 between and among HVWC, the Company, and HAC, Inc., the Company’s wholly-owned Connecticut subsidiary (the “Merger Agreement”). HVWC serves approximately 4,700 water customers in the Towns of Southbury, Middlebury, and Oxford, Connecticut and approximately 3,000 wastewater customers in the Town of Southbury, Connecticut.

The acquisition was executed through a stock-for-stock merger transaction valued at approximately $16.9 million. Holders of HVWC common stock received shares of the Company’s common stock in a tax-free exchange. In addition, the transaction reflected a total enterprise value of HVWC of approximately $21.5 million, with the $16.9 million paid to shareholders in a stock exchange and the assumption by the Company of approximately $4.6 million of debt held by HVWC at the time of the acquisition.

The Company received regulatory approval from MPUC on September 28, 2016 and from PURA on December 5, 2016, to proceed with the transaction. The shareholders of HVWC voted to approve the acquisition at a special meeting of HVWC’s shareholders held on February 27, 2017.

On February 27, 2017, the Company completed the acquisition of HVWC by completing the merger of the Company’s wholly-owned subsidiary HAC, Inc. with and into HVWC, with HVWC as the surviving corporation, pursuant to the terms of the Merger Agreement and Connecticut corporate law. Upon the effective time of the Merger, the holders of HVWC’s 1,620 issued and outstanding shares of common stock became entitled to receive an aggregate of 300,445 shares of the Company’s common stock in a tax-free exchange, which exchange was commenced promptly by the issuance of a letter of transmittal and related materials by Connecticut Water’s exchange agent.

The Avon Water Company Acquisition

On October 12, 2016, the Company announced that it had reached an agreement to acquire Avon Water, pending a vote of Avon Water shareholders, approval by PURA and the MPUC and the satisfaction of other various closing conditions, pursuant to the terms of that certain Agreement and Plan of Merger dated October 11, 2016 as amended on March 29, 2017 between and among Avon Water, the Company, and WC-A I, Inc., the Company’s wholly-owned Connecticut subsidiary (the “Merger Agreement”). Avon Water serves approximately 4,800 customers in the Farmington Valley communities of Avon, Farmington, and Simsbury, Connecticut.

On February 10, 2017, Connecticut Water received regulatory approval from MPUC and on April 12, 2017, Connecticut Water received regulatory approval from the PURA to proceed with the transaction. The shareholders of Avon Water voted to approve the acquisition at a special meeting of Avon Water’s shareholders held on June 16, 2017.

Effective July 1, 2017, the Company completed the acquisition of Avon Water by completing the merger of Connecticut Water’s wholly-owned subsidiary WC-A I, Inc. with and into Avon Water, with Avon Water as the surviving corporation, pursuant to the terms of the Merger Agreement and Connecticut corporate law. Upon the effective time of the Merger, the holders of Avon Water’s 122,289 issued and outstanding shares of common stock became entitled to receive the following merger consideration for each share of Avon Water common stock held: (i) a cash payment of $50.11; and (ii) a stock consideration component, consisting of 3.97 shares of the Company’s common stock.

The transaction was completed through a stock-for-stock exchange where Avon Water shareholders received the Company’s common stock valued at approximately $26.9 million, in a tax-free exchange, and a cash payment of $6.1 million for a total payment to shareholders of $33.0 million. The transaction reflects a total enterprise value of approximately $39.1 million, with the $33.0 million paid to shareholders and the assumption by the Company of approximately $6.1 million of debt of Avon Water.

The following table summarizes the fair value of the HVWC assets acquired on February 27, 2017 and the Avon Water assets on July 1, 2017, the dates of the acquisitions (in thousands):

Contributions in Aid of Construction	18,452		11,560
Net Assets Acquired	$	16,903	$	32,744

The estimated fair values of the assets acquired and the liabilities assumed were determined based on the accounting guidance for fair value measurement under GAAP, which defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value analysis assumes the highest and best use of the assets by market participants. The allocation of the purchase price includes an adjustment to fair value related to the fair value of HVWC’s and Avon Water’s long term debt and any associated deferred taxes. Additionally, adjustments were made to deferred taxes based on the Company’s ability to utilize net operating loss carryforwards that had valuation allowances at the acquired companies. The excess of the purchase price paid over the estimated fair value of the assets acquired and the liabilities assumed was recognized as goodwill, none of which is deductible for tax purposes. Goodwill recognized as part of the acquisitions of HVWC and Avon Water are a part of the Company’s Water Operations segment.

The following unaudited pro forma summary for the three and six months endedJune 30, 2018 and 2017 presents information as if HVWC and Avon Water had each been acquired on January 1, 2017 and assumes that there were no other changes in our operations.  The following pro forma information does not necessarily reflect the actual results that would have occurred had the Company operated the businesses since January 1, 2017, nor is it necessarily indicative of the future results of operations of the combined companies (in thousands):

Revenue from Contracts with Customers (Notes)

Revenue from Contract with Customer [Text Block]

5. Revenues from Contracts with Customers

Accounting Policy

Our revenues are primarily from tariff-based sales. We provide water and wastewater services to customers under these tariffs without a defined contractual term (at-will).  As the revenue from these arrangements is based upon the amount of the water and wastewater services supplied and billed in that period (including estimated billings), there was not a shift in the timing or pattern of revenue recognition for such sales when compared to our revenue recognition prior to the adoption of ASU 2014-09.  We have also completed the evaluation of our other revenue streams, including those tied to longer term contractual commitments and the Company’s Linebacker program.

Customers are primarily billed quarterly on a cycle basis. To match revenues with associated expenses, we accrue unbilled revenues for water and wastewater services delivered to customers, but not yet billed at month end, creating a contract asset.

Nature of Goods and Services

Water Operations - We currently provide retail water and wastewater services to five primary customer classes. Our largest customer class consists of residential customers, which include single private dwellings and individual apartments. Our commercial class consists primarily of main street businesses, our industrial class consists primarily of manufacturing and processing businesses that turn raw materials into products, our public authority class represents services provided primarily to municipality or other government customers, and, finally, our fire protection class consists of services related to fire suppression systems and fire hydrants. Connecticut Water’s management has determined that tariff-based receipts; except for the WRA and other deferred revenue mechanisms, which are considered alternative revenue programs; are considered revenues from contracts with customers.

• The Company has performance obligations for the service of standing ready to deliver water to customers. The Company recognizes revenue at a fixed rate as it provides these services, as approved by regulators. These arrangements generally do not have fixed terms and remain in effect as long as the customer consumes the utility service. The rates are set by PURA and the MPUC through the rate-making process and represent the stand-alone selling price of Company’s service to stand ready to deliver.

• The Company has performance obligations for the service of delivering the commodity of water to customers. The Company recognizes revenue at a price per unit of water delivered (gallons, cubic feet, etc.), based on the tariffs established by our regulators. These arrangements generally do not have fixed terms and remain in effect as long as the customer consumes the utility service. The rates are set by PURA and the MPUC through the rate-making process and represent the stand-alone selling price of a bundled product comprising the commodity and the service of delivering such commodity.

• The Company has a performance obligation related to administrative services such as turn-on/turn-off services, assessment of late charges, etc. The Company views that these services are not distinct in the context of the contract because they are highly interdependent for the effective delivery of water service provided to consumers.

Based on the above discussion, the Company believes that the Goods and Services provided under customer contracts constitute a single performance obligation. The Company believes that this performance obligation is satisfied over time.

Services and Rentals - We provide contracted services to water utilities and other clients and also lease certain of our properties to third parties. The types of services provided include contract operations of water; Linebacker, our service line protection plan for public drinking water customers; and providing bulk deliveries of emergency drinking water to businesses and residences via tanker truck. Our lease and rental income comes primarily from the renting of residential and commercial property. The goods and services provided by Linebacker have been determined to be based on the stand ready nature of the Company to provide the goods and services and, therefore, customers simultaneously receive and consume the benefits provided by the Company. The other revenue streams in the Services and Rentals segment, including contracted services to water utilities and other clients, have performance obligations that are satisfied at a point in time, and likewise will not have a shift in the timing or pattern of revenue recognition.

The following table show the components of Accounts Receivable and Accrued Unbilled Revenues related to revenues from contracts with customers:

	June 30, 2018		December 31, 2017

Other accounts receivable	1,178		1,973
Total Accounts Receivable	$	13,262	$	14,965
Accrued Unbilled Revenues from Contracts with Customers	$	9,732	$	8,481

Accounts Receivable and Accrued Unbilled Revenues: Accounts receivable are comprised of trade receivables primarily from our regulated water customers. The Company records their accounts receivable at cost, which approximates fair value. Additionally, the Company establishes an allowance for uncollectible accounts based on historical losses, management’s assessment of existing economic conditions, customer payment trends, and other factors. The Company assesses late payment fees on trade receivables based on contractual past-due terms established with customers and approved by PURA or the MPUC. The provision for bad debts is charged to operating expense.

The Company’s customers are primarily billed quarterly in cycles having billing dates that do not generally coincide with the end of a fiscal quarter. This results in customers having received water or waste water services that they have not been billed for as of a given period’s end. The Company estimates its unbilled revenues by applying an average billed rate to total unbilled deliveries for each customer class.
