Note 1 – Organization, Summary of Significant Accounting Policies and Recent Developments

(a) Organization - Middlesex Water Company (Middlesex) is the parent company and sole shareholder of Tidewater Utilities, Inc. (Tidewater), Tidewater Environmental Services, Inc. (TESI), Pinelands Water Company (Pinelands Water) and Pinelands Wastewater Company (Pinelands Wastewater) (collectively, Pinelands), Utility Service Affiliates, Inc. (USA), Utility Service Affiliates (Perth Amboy) Inc. (USA-PA) and Twin Lakes Utilities, Inc. (Twin Lakes). Southern Shores Water Company, LLC (Southern Shores) and White Marsh Environmental Systems, Inc. (White Marsh) are wholly-owned subsidiaries of Tidewater.

Middlesex Water Company has operated as a water utility in New Jersey since 1897, in Delaware, through our wholly-owned subsidiary, Tidewater, since 1992 and in Pennsylvania, through our wholly-owned subsidiary, Twin Lakes, since 2009. We are in the business of collecting, treating, distributing and selling water for domestic, commercial, municipal, industrial and fire protection purposes. We also operate New Jersey municipal water, wastewater and storm water systems under contract and provide unregulated water and wastewater services in New Jersey and Delaware through our subsidiaries. Our rates charged to customers for water and wastewater services, the quality of services we provide and certain other matters are regulated in New Jersey, Delaware and Pennsylvania by the New Jersey Board of Public Utilities (NJBPU), Delaware Public Service Commission (DEPSC) and Pennsylvania Public Utilities Commission (PAPUC), respectively. Our USA, USA-PA and White Marsh subsidiaries are not regulated utilities.

Certain reclassifications have been made to the prior year financial statements to conform with current period presentation. The reclassifications are immaterial to the overall presentation of our consolidated financial statements.

(b) Principles of Consolidation– The financial statements for Middlesex and its wholly-owned subsidiaries (the Company) are reported on a consolidated basis. All significant intercompany accounts and transactions have been eliminated. Other financial investments in which the Company holds a 50% or less voting interest and cannot exercise control over the operation and policies of the investments are accounted for under the equity method of accounting. Under the equity method of accounting, the Company records its investment interests in Non-Utility Assets and its percentage share of the earnings or losses of the investees in Other Income (Expense).

(c) System of Accounts– Middlesex, Pinelands Water and Pinelands Wastewater maintain their accounts in accordance with the Uniform System of Accounts prescribed by the NJBPU. Tidewater, TESI and Southern Shores maintain their accounts in accordance with DEPSC requirements. Twin Lakes maintains its accounts in accordance with PAPUC requirements.

(d) Regulatory Accounting - We maintain our books and records in accordance with accounting principles generally accepted in the United States of America. Middlesex and certain of its subsidiaries, which account for 91% of Operating Revenues and 99% of Total Assets, are subject to regulation in the state in which they operate. Those companies are required to maintain their accounts in accordance with regulatory authorities’ rules and guidelines, which may differ from other authoritative accounting pronouncements. In those instances, the Company follows the guidance provided in Accounting Standards Codification (ASC) 980, Regulated Operations.

In accordance with ASC 980, Regulated Operations, costs and obligations are deferred if it is probable that these items will be recognized for rate-making purposes in future rates. Accordingly, we have recorded costs and obligations, which will be amortized over various future periods. Any change in the assessment of the probability of rate-making treatment will require us to change the accounting treatment of the deferred item. We have no reason to believe any of the deferred items that are recorded will be treated differently by the regulators in the future. For additional information, see Note 2 – Rate and Regulatory Matters.

(e) Retirement Benefit Plans - We maintain a noncontributory defined benefit pension plan (Pension Plan) which covers all active employees who were hired prior to April 1, 2007. In addition, the Company maintains an unfunded supplemental plan for a limited number of its executive officers. The Company has a retirement benefit plan other than pensions (Other Benefits Plan) for substantially all of its retired employees. Employees hired after March 31, 2007 are not eligible to participate in this plan. Coverage includes healthcare and life insurance.

The Company’s costs for providing retirement benefits are dependent upon numerous factors, including actual plan experience and assumptions of future experience. Retirement benefit plan obligations and expense are determined based on investment performance, discount rates and various other demographic factors related to the population participating in the Company’s retirement benefit plans, all of which can change significantly in future years. For more information on the Company’s Retirement Benefit Plans, see Note 7 – Employee Benefit Plans.

(f) Utility Plant– Utility Plant is stated at original cost as defined for regulatory purposes. Property accounts are charged with the cost of betterments and major replacements of property. Cost includes direct material, labor and indirect charges for pension benefits and payroll taxes. The cost of labor, materials, supervision and other expenses incurred in making repairs and minor replacements and in maintaining the properties is charged to the appropriate expense accounts. At December 31, 2019, there was no event or change in circumstance that would indicate that the carrying amount of any long-lived asset was not recoverable.

(g) Depreciation – Depreciation is computed by each regulated member of the Company utilizing a rate approved by the applicable regulatory authority. The accumulated provision for depreciation is charged with the cost of property retired, less salvage. The following table sets forth the range of depreciation rates for the major utility plant categories used to calculate depreciation for the years ended December 31, 2019, 2018 and 2017. These rates have been approved by the NJBPU, DEPSC or PAPUC:

Source of Supply	1.15% - 3.44%	Transmission and Distribution (T&D):
Pumping	2.00% - 5.39%	T&D – Mains	1.10% - 3.13%
Water Treatment	1.65% - 7.09%	T&D – Services	2.12% - 3.16%
General Plant	2.08% - 17.84%	T&D – Other	1.61% - 4.63%
Wastewater Collection	1.42% - 1.81%

Non-regulated fixed assets consist primarily of office buildings, furniture and fixtures, and transportation equipment. These assets are recorded at original cost and depreciation is calculated based on the estimated useful lives, ranging from 3 to 42 years.

(h) Preliminary Survey and Investigation (PS&I)Costs – In the design of water and wastewater systems that the Company ultimately intends to construct, own and operate certain expenditures are incurred to advance those project activities. These PS&I costs are recorded as deferred charges on the balance sheet because these costs are expected to be recovered through future rates charged to customers as the underlying projects are placed into service as utility plant. If it is subsequently determined that costs for a project recorded as PS&I are not recoverable through rates charged to our customers, the applicable PS&I costs are recorded as Other Expense on the statement of income at that time.

(i) Customers’ Advances for Construction (CAC) – Utility plant and/or cash advances are provided to the Company by customers, real estate developers and builders in order to extend utility service to their properties. These transactions are recorded as CAC. Contractual Refunds of CACs in the form of cash are made by the Company and are based on either additional operating revenues generated from new customers or as new customers are connected to the respective system. After all refunds are made and/or contract terms have expired, any remaining balance is transferred to Contributions in Aid of Construction.

Contributions in Aid of Construction(CIAC) – CIAC include direct non-refundable contributions of utility plant and/or cash and the portion of CAC that becomes non-refundable.

Index

CAC and CIAC are not depreciated in accordance with regulatory requirements. In addition, these amounts reduce the investment base for purposes of setting rates.

(j) Allowance for Funds Used During Construction (AFUDC) - Middlesex and its regulated subsidiaries capitalize AFUDC, which represents the cost of financing projects during construction. AFUDC is added to the construction costs of individual projects exceeding specific cost and construction period thresholds established for each company and then depreciated along with the rest of the utility plant’s costs over its estimated useful life. AFUDC is calculated using each company’s weighted cost of debt and equity as approved in their most recent respective regulatory rate order. The AFUDC rates for the years ended December 31, 2019, 2018 and 2017 for Middlesex and Tidewater are as follows:

	2019	2018	2017
Middlesex	6.50%	6.50%	6.73%
Tidewater	7.92%	7.92%	7.92%

(k) Accounts Receivable – We record bad debt expense based on historical write-offs combined with an evaluation of current conditions. The allowance for doubtful accounts was $1.4 million and $1.0 million as of December 31, 2019 and 2018, respectively. For the years ended December 31, 2019, 2018 and 2017, bad debt expense was $1.0 million, $0.8 million and $0.5 million, respectively. For the years ended December 31, 2019, 2018 and 2017, write-offs were $0.6 million, $0.7 million and $0.5 million, respectively.

(l) Revenues - The Company’s revenues are primarily generated from regulated tariff-based sales of water and wastewater services and non-regulated operation and maintenance contracts for services on water and wastewater systems owned by others.Revenue from contracts with customers is recognized when control of a promised good or service is transferred to customers at an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services.

The Company’s regulated revenue from contracts with customers is derived from tariff-based sales that result from the obligation to provide water and wastewater services to residential, industrial, commercial, fire-protection and wholesale customers. The Company’s residential customers are billed quarterly while most of the Company’s industrial, commercial, fire-protection and wholesale customers are billed monthly. Payments by customers are due between 15 to 30 days after the invoice date. The Company recognizes revenue as the water and wastewater services are delivered to customers as well as records unbilled revenues estimated from the last meter reading date to the end of the accounting period utilizing factors such as historical customer data, regional weather indicators and general economic conditions in its service territories. Unearned Revenues and Advance Service Fees include fixed service charge billings in advance to Tidewater customers that are recognized as service is provided to the customer.

Non-regulated service contract revenues consist of base service fees as well as fees for additional billable services provided to customers. Fees are billed monthly and are due within 30 days after the invoice date. The Company considers the amounts billed to represent the value of these services provided to customers. These contracts expire at various times through December 2028 and thus contain remaining performance obligations for which the Company expects to recognize revenue in the future. These contracts also contain customary termination provisions.

Almost all of the amounts included in operating revenues and accounts receivable are from contracts with customers. The Company records its allowance for doubtful accounts based on historical write-offs combined with an evaluation of current economic conditions within its service territories.

The Company’s contracts do not contain any significant financing components.

(m) Unamortized Debt Expense and Premiums on Long-Term Debt - Unamortized Debt Expense and Premiums on Long-Term Debt, included on the consolidated balance sheet in long-term debt, are amortized over the lives of the related debt issues.

(n) Income Taxes - Middlesex files a consolidated federal income tax return for the Company and income taxes are allocated based on the separate return method. Investment tax credits have been deferred and are amortized over the estimated useful life of the related property. In the event that there are interest and penalties associated with income tax adjustments from income tax authority examinations, these amounts will be reported under interest expense and other expense, respectively. For more information on income taxes, see Note 3 – Income Taxes.

(o) Cash and Cash Equivalents - For purposes of reporting cash flows, the Company considers all highly liquid investments with original maturity dates of three months or less to be cash equivalents. Cash and cash equivalents represent bank balances and money market funds with investments maturing in less than 90 days.

(p) Restricted Cash – Restricted cash includes cash proceeds from loan transactions entered into through government financing programs and are held in trusts for specific capital expenditures or debt service.

(q) Use of Estimates - Conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts in the financial statements. Actual results could differ from those estimates.

(r) Recent Accounting Pronouncements

Revenue Recognition - The Financial Accounting Standards Board (FASB) issued guidance, which replaces most of the existing guidance with a single set of principles for recognizing revenue from contracts with customers. The guidance became effective January 1, 2018 and did not have a material impact on the Company’s financial statements. Disclosures related to Revenue Recognition are included above in Revenues.

Recognition and Measurement of Financial Assets and FinancialLiabilities - The FASB issued guidance which (i) requires all investments in equity securities, except those accounted for under the equity method of accounting or that result in consolidation of the investee, unincorporated joint ventures and limited liability companies, to be carried at fair value through net income, (ii) requires an incremental recognition and disclosure requirement related to the presentation of fair value changes of financial liabilities for which the fair value option has been elected, (iii) amends several disclosure requirements, including the methods and significant assumptions used to

Index

estimate fair value or a description of the changes in the methods and assumptions used to estimate fair value, and (iv) requires disclosure of the fair value of financial assets and liabilities measured at amortized cost at the amount that would be received to sell the asset or paid to transfer the liability. The guidance became effective January 1, 2018 and did not have a material impact on the Company’s financial statements.

Statement of Cash Flows - The FASB issued guidance which amends the previous guidance on the classification of certain cash receipts and payments in the statement of cash flows. The primary purpose of the amendment is to reduce the diversity in practice that has resulted from the lack of consistent principles on this topic. The guidance became effective January 1, 2018 and did not have a material impact on the Company’s financial statements.

Restricted Cash - The FASB issued guidance related to the classification and presentation of restricted cash in the statement of cash flows, which requires entities to a) include restricted cash balances in its cash and cash-equivalent balances in the statement of cash flows and b) include a reconciliation of cash and cash-equivalents per the statement of financial position as compared to the statement of cash flows. Changes in restricted cash and restricted cash equivalents that result from transfers between cash, cash equivalents, and restricted cash and restricted cash equivalents will not be presented as cash flow activities in the statement of cash flows. In addition, an entity with a material balance of amounts described as restricted cash and restricted cash equivalents must disclose information about the nature of the restrictions. The guidance became effective January 1, 2018 and did not have a material impact on the Company’s financial statements.

Employee Benefit Plans-Net Periodic Benefit Cost – The FASB issued guidance which requires entities to (1) disaggregate the current-service-cost component from the other components of net benefit cost and present it with other current compensation costs for related employees in the income statement and (2) present the other components elsewhere in the income statement and outside of income from operations if that subtotal is presented. In addition, the guidance requires entities to disclose the income statement lines that contain the other components if they are not presented on appropriately described separate lines. The guidance became effective January 1, 2018 and did not have a material impact on the Company’s financial statements. As a result of adopting this guidance, the consolidated statement of income for the year ended December 31, 2017 was revised, which resulted in increases in Operations and Maintenance expense and Other Income (Expense), net of $0.8 million.

Leases - The FASB issued guidance related to leases which requires lessees to recognize a lease liability (a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis) and a right-of-use asset (an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term). The guidance became effective on January 1, 2019. The Company elected the optional transition method of adoption option to apply the requirements of the standard in the period of adoption with no restatement of prior periods. The Company utilized the package of transition practical expedients provided by the new guidance, including carrying forward prior conclusions related to contracts that contain leases and lease classification. The Company also utilized the transition practical expedient permitting entities to forgo the evaluation of existing land easement arrangements to determine if they contain a lease. Land easement arrangements, or modifications to existing arrangements, entered into after adoption of this guidance will need to be evaluated to determine if they meet the definition of a lease. The adoption of this guidance resulted in the recording of a $6.7 million right-of-use asset, a $7.1 million lease liability and a $0.4 million regulatory asset on the Company’s consolidated balance sheet as of January 1, 2019. For further discussion, see “Leases” in Note 4 – Commitments and Contingent Liabilities.

There are no other new adopted or proposed accounting guidance that the Company is aware of that could have a material impact on the Company’s consolidated financial statements.
