NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Note 1 – Basis of Presentation and Recent Developments

Middlesex Water Company (Middlesex or the Company) 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. 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.

The consolidated notes within the 2018 Annual Report on Form 10-K (2018 Form 10-K) are applicable to these financial statements and, in the opinion of the Company, the accompanying unaudited condensed consolidated financial statements contain all adjustments necessary (including normal recurring accruals) to present fairly the financial position as of June 30, 2019 and the results of operations and cash flows for the three month and six month periods ended June 30, 2019 and 2018. Information included in the Condensed Consolidated Balance Sheet as of December 31, 2018, has been derived from the Company’s audited financial statements for the year ended December 31, 2018 included in the 2018 Form 10-K.

Recently Adopted Accounting Guidance

Leases - On January 1, 2019, the Company adopted Financial Accounting Standards Board (FASB) issued guidance related to leases which required lessees to recognize a lease liability and a right-of-use asset. 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 7 – 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 financial statements.

Note 2 – Rate and Regulatory Matters

Middlesex – In December 2018, the New Jersey Board of Public Utilities (NJBPU) approved Middlesex’s petition to establish its Purchased Water Adjustment Clause (PWAC) tariff rate to recover additional annual costs of less than $0.1 million, primarily for the purchase of treated water from a non-affiliated water utility regulated by the NJBPU. A PWAC is a rate mechanism that allows for recovery of increased purchased water costs between base rate case filings. The PWAC is reset to zero once those increased costs are included in base rates. The PWAC tariff rate became effective on January 1, 2019.

Tidewater - Effective July 1, 2019, Tidewater reset its Delaware Public Service Commission (DEPSC) approved Distribution System Improvement Charge rate, which is expected to generate revenues of approximately $0.5 million annually.

In February 2019, Tidewater received approval from the DEPSC to reduce its rates, effective March 1, 2019, to reflect the lower corporate income tax rate enacted by the Tax Cuts and Jobs Act of 2017 (Tax Act) , resulting in an overall rate decrease of 3.35%, or $1.0 million of revenues, on an annual basis. The DEPSC also approved a one-time credit of $0.7 million to customers’ accounts related to the lower corporate income tax rate.

Pinelands - In March 2019, Pinelands Water and Pinelands Wastewater filed separate petitions with the NJBPU seeking permission to increase base rates by approximately $0.2 million and $0.5 million per year, respectively. These requests were necessitated by capital infrastructure investments both companies have made, or have committed to make, and increased operations and maintenance costs. We cannot predict whether the NJBPU will ultimately approve, deny, or reduce the amount of the requests. A decision by the NJBPU in either matter is not expected before the fourth quarter of 2019.

Twin Lakes - In July 2019, Twin Lakes filed a petition with the Pennsylvania Public Utilities Commission (PAPUC) seeking permission to increase base rates by approximately $0.2 million per year. This request was necessitated by capital infrastructure investments Twin Lakes has made, or has committed to make, and increased operations and maintenance costs. We cannot predict whether the PAPUC will ultimately approve, deny, or reduce the amount of the request. A decision by the PAPUC is not expected before the first quarter of 2020.

Note 3 – Capitalization

Common Stock - During the six months ended June 30, 2019 and 2018, there were 129,675 common shares ($7.1 million) and 15,026 common shares (approximately $0.6 million), respectively, issued under the Middlesex Water Company Investment Plan (Investment Plan). On January 2, 2019, the Company began offering shares of its common stock for purchase at a 5% discount to participants in the Investment Plan. The discount offering will continue until 200,000 shares are purchased at the discounted price or December 30, 2019, whichever event occurs first.  The discount applies to all common stock purchases made under the Investment Plan, whether by optional cash payment or by dividend reinvestment.

In May 2019, Middlesex received approval from the NJBPU to issue and sell up to 1,500,000 shares of its common stock in one or more transactions through December 31, 2022. Sales of additional shares of common stock are part of the Company’s comprehensive financing plan to fund its multi-year utility plant infrastructure investment program. As described below in “ Long-term Debt” , the NJBPU approved the New Jersey Economic Development Authority (NJEDA) debt funding component of the financing plan.

Long-term Debt - Subject to regulatory approval, the Company periodically issues long-term debt to fund its investments in utility plant and other assets. To the extent possible, the Company finances qualifying capital projects under State Revolving Fund (SRF) loan programs in New Jersey and Delaware. These government programs provide financing at interest rates that are typically below rates available in the broader financial markets. A portion of the borrowings under the New Jersey SRF is interest-free. Under the New Jersey SRF program, borrowers first enter into a construction loan agreement with the New Jersey Infrastructure Bank (NJIB) at a below market interest rate. The current interest rate on construction loan borrowings is zero percent (0%). When construction on the qualifying project is substantially complete, NJIB will coordinate the conversion of the construction loan into a long-term securitized loan with a portion of the principal balance having a stated interest rate of zero percent (0%) and a portion of the principal balance at a market interest rate at the time of closing using the credit rating of the State of New Jersey. The current term of the long-term loans offered through the NJIB is up to thirty years. The current portion of the principal balance having a stated interest rate of zero percent (0%) is 75% with the remaining portion of 25% having a market based interest rate.

The NJIB generally schedules its long-term debt financings in May and November. Middlesex currently has two projects that are in the construction loan phase of New Jersey SRF program:

In May 2018, Middlesex repaid its $9.5 million RENEW 2017 interest-free construction loan by issuing to the NJIB first mortgage bonds designated as Series 2018A ($7.1 million) and Series 2018B ($2.4 million). The interest rate on the Series 2018A bond is zero and the interest rate on the Series 2018B bond ranges between 3.0% and 5.0%. Through June 30, 2019, Middlesex has drawn a total of $8.9 million and expects to finish drawing on this loan during the third quarter of 2019. The final maturity date for both bonds is August 1, 2047, with scheduled debt service payments over the life of the loans.

In order to help ensure adherence to its comprehensive financing plan, Middlesex received approval from the NJBPU in February 2019 to issue and sell up to $140 million of First Mortgage Bonds (FMB) through the NJEDA in one or more transactions through December 31, 2022. Because the interest paid to the bondholders is exempt from federal and New Jersey income taxes, the interest rate on FMB issued through the NJEDA is generally lower than otherwise achievable in the traditional taxable corporate bond market. However, the interest is subject to the Alternative Minimum Tax. Middlesex has selected an underwriter to market and sell up to $60 million of FMB in August 2019.

In March 2018, the DEPSC approved Tidewater’s request to borrow up to $0.9 million under the Delaware SRF program to fund the replacement of an entire water distribution system of a small Delaware subdivision. Tidewater closed on this SRF loan in May 2018. In April 2019, Tidewater received approval from the DEPSC to increase the borrowing to $1.7 million based on revised project cost estimates. Tidewater expects to close on this additional SRF loan in August 2019 and expects to draw down on the loan beginning in the fourth quarter of 2019 through the second quarter of 2020.

In 2019, the NJIB de-obligated principal payments of $0.1 million on Series NN of the Company’s First Mortgage Bonds.

Fair Value of Financial Instruments - The following methods and assumptions were used by the Company in estimating its fair value disclosure for financial instruments for which it is practicable to estimate that value. The carrying amounts reflected in the condensed consolidated balance sheets for cash and cash equivalents, trade receivables, accounts payable and notes payable approximate their respective fair values due to the short-term maturities of these instruments. The fair value of FMB and State Revolving Fund Bonds (collectively, the Bonds) issued by Middlesex is based on quoted market prices for similar issues. Under the fair value hierarchy, the fair value of cash and cash equivalents is classified as a Level 1 measurement and the fair value of notes

payable and the Bonds in the table below are classified as Level 2 measurements. The carrying amount and fair value of the Bonds were as follows:

For other long-term debt for which there was no quoted market price and there is not an active trading market, it was not practicable to estimate their fair value (for details, including carrying value, interest rate and due date on these series of long-term debt, please refer to those series noted as “Amortizing Secured Note”, “State Revolving Trust Note” and “Construction Loans” on the Condensed Consolidated Statements of Capital Stock and Long-Term Debt). The carrying amount of these instruments was $72.9 million and $61.5 million at June 30, 2019 and December 31, 2018, respectively. Customer advances for construction have carrying amounts of $23.4 million and $22.6 million at June 30, 2019 and December 31, 2018, 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.

Note 4 – Earnings Per Share

Basic earnings per share (EPS) are computed on the basis of the weighted average number of shares outstanding during the period presented. Diluted EPS assumes the conversion of both the Convertible Preferred Stock $7.00 Series and the Convertible Preferred Stock $8.00 Series.

Note 5 – Business Segment Data

The Company has identified two reportable segments. One is the regulated business of collecting, treating and distributing water on a retail and wholesale basis to residential, commercial, industrial and fire protection customers in parts of New Jersey, Delaware and Pennsylvania. This segment also includes regulated wastewater systems in New Jersey and Delaware. The Company is subject to regulations as to its rates, services and other matters by New Jersey, Delaware and Pennsylvania with respect to utility services within these states. The other segment is primarily comprised of non-regulated contract services for the operation and maintenance of municipal and private water and wastewater systems in New Jersey and Delaware. Inter-segment transactions relating to operational costs are treated as pass-through expenses. Finance charges on inter-segment loan activities are based on interest rates that are below what would normally be charged by a third party lender.

Note 6 – Short-term Borrowings

As of June 30, 2019, the Company retains lines of credit aggregating $100.0 million. At June 30, 2019, the outstanding borrowings under these credit lines were $59.4 million at a weighted average interest rate of 3.41%.

The weighted average daily amounts of borrowings outstanding under the Company’s credit lines and the weighted average interest rates on those amounts were as follows:

The maturity dates for the $59.4 million outstanding as of June 30, 2019 are in July 2019 through September 2019 and are extendable at the discretion of the Company.

Interest rates for short-term borrowings under the lines of credit are below the prime rate with no requirement for compensating balances.

Note 7 – Commitments and Contingent Liabilities

Water Supply - Middlesex has an agreement with the New Jersey Water Supply Authority (NJWSA) for the purchase of untreated water through November 30, 2023, which provides for an average purchase of 27.0 million gallons a day (mgd). Pricing is set annually by the NJWSA through a public rate making process. The agreement has provisions for additional pricing in the event Middlesex overdrafts or exceeds certain monthly and annual thresholds.

Middlesex also has an agreement with a non-affiliated regulated water utility for the purchase of treated water. This agreement, which expires February 27, 2021, provides for the minimum purchase of 3.0 mgd of treated water with provisions for additional purchases.

Tidewater contracts with the City of Dover, Delaware to purchase 15.0 million gallons of treated water annually.

Purchased water costs are shown below:

Guarantees - As part of an agreement with the County of Monmouth, New Jersey (County), Middlesex serves as guarantor of the performance of Applied Water Management, Inc. (AWM), an unaffiliated wastewater contractor, to operate a County-owned leachate pretreatment facility at the Monmouth County Reclamation Center in Tinton Falls, New Jersey. The performance guaranty is effective through 2028 unless another guarantor, acceptable to the County, replaces Middlesex before such date. Under agreements with AWM and Natural Systems Utilities, LLC (NSU), the parent company of AWM, Middlesex earns a fee for providing the performance guaranty. In addition, Middlesex may provide operational support to the facility, as needed, and AWM and NSU, serving as guarantor to Middlesex with respect to the performance of AWM, have indemnified Middlesex against any claims that may arise under the Middlesex guaranty to the County.

If requested to perform under the guaranty to the County and, if AWM and NSU, as guarantor to Middlesex, do not fulfill their obligations to indemnify Middlesex against any claims that may arise under the Middlesex guaranty to the County, Middlesex would be required to fulfill the remaining operational commitment of AWM. As of both June 30, 2019 and December 31, 2018, the liability recognized in Other Non-Current Liabilities on the balance sheet for the guaranty is approximately $1.5 million.

Leases - The Company determines if an arrangement is a lease at inception. Generally, a lease agreement exists if the Company determines that the arrangement gives the Company control over the use of an identified asset and obtains substantially all of the benefits from the identified asset.

The Company has entered into an operating lease of office space for administrative purposes, expiring in 2030. The Company has not entered into any finance leases. The exercise of a lease renewal option for the Company’s administrative offices is solely at the discretion of the Company.

The right-of-use (ROU) asset recorded represents the Company’s right to use an underlying asset for the lease term and lease liability represents the Company’s obligation to make lease payments arising from the lease. Lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. The Company’s operating lease does not provide an implicit discount rate and as such the Company used an estimated incremental borrowing rate (4.03%) based on the information available at commencement date in determining the present value of lease payments.

Given the impacts of accounting for regulated operations, and the resulting recognition of expense at the amounts recovered in customer rates, expenditures for operating leases are consistent with lease expense and were $0.1 million and less than $0.1 million for the three months ended June 30, 2019 and 2018, respectively and $0.3 million and $0.1 million for the six months ended June 30, 2019 and 2018, respectively.

Information related to operating lease ROU assets and lease liabilities is as follows:

The Company’s future minimum operating lease commitments as of June30, 2019 are as follows:

Construction - The Company has forecasted to spend approximately $116 million for its construction program in 2019. The Company has entered into several contractual construction agreements that, in the aggregate, obligate it to expend an estimated $77 million in the future. The timing and amount of capital expenditures is dependent on project scheduling and refinement of engineering estimates for certain projects.

Litigation - The Company is a defendant in lawsuits in the normal course of business. We believe the resolution of pending claims and legal proceedings will not have a material adverse effect on the Company’s consolidated financial statements.

Change in Control Agreements - The Company has Change in Control Agreements with certain of its officers that provide compensation and benefits in the event of termination of employment in connection with a change in control of the Company.

Note 8 – Employee Benefit Plans

Pension Benefits - The Company’s Pension Plan covers all active employees hired prior to April 1, 2007. Employees hired after March 31, 2007 are not eligible to participate in this plan, but do participate in a defined contribution plan that provides for a potential annual contribution in an amount that is at the discretion of the Company. In order to be eligible for a contribution, the participant must be employed by the Company on December 31st of the year to which the contribution relates. For the three months ended June 30, 2019 and 2018, the Company made Pension Plan cash contributions of $0.5 million and $0.8 million, respectively. For the six months ended June 30, 2019 and 2018, the Company made Pension Plan cash contributions of $1.0 million and $1.3 million, respectively. The Company expects to make Pension Plan cash contributions of approximately $2.6 million over the remainder of the current year. The Company also maintains an unfunded supplemental retirement benefit plan for certain active and retired Company officers and currently pays $0.4 million in annual benefits to the retired participants.

Other Postretirement Benefits - The Company’s retirement plan other than pensions (Other Benefits Plan) covers substantially all of its current retired employees. Employees hired after March 31, 2007 are not eligible to participate in this plan. Coverage includes healthcare and life insurance. For each of the three months ended June 30, 2019 and 2018, the Company made Other Benefits Plan cash contributions of $0.2 million, respectively. For each of the six months ended June 30, 2019 and 2018, the Company made Other Benefits Plan cash contributions of $0.4 million, respectively. The Company expects to make Other Benefits Plan cash contributions of approximately $1.0 million over the remainder of the current year.

The following tables set forth information relating to the Company’s periodic costs for its employee retirement benefit plans:

Note 9 – Revenue Recognition from Contracts with Customers

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 and 30 days after the invoice date. The Company recognizes revenue as the water and wastewater services are delivered to customers and 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 of service provided to Tidewater customers and are recognized as service is provided.

Non-regulated service contract revenues consist of base service fees, as well as fees for additional billable services provided to customers, 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. Certain of these contracts continue through 2022 and thus contain remaining performance obligations for which the Company expects to recognize revenue in the future. These contracts also contain termination provisions.

Substantially all operating revenues and accounts receivable are from contracts with customers. The Company records an 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.

The Company’s operating revenues are comprised of the following:

Note 10 – Income Taxes

As part of its 2014 Federal income tax return, the Company adopted the final Internal Revenue Service (IRS) tangible property regulations and changed its accounting method for the tax treatment of expenditures that qualified as deductible repairs. The adoption resulted in a net reduction of $17.6 million in taxes previously remitted to the IRS, for which the Company has already sought and received the tax refunds. A reserve provision against refunded taxes of $2.3 million was recorded in 2015 at the time of filing its change in accounting method based on a possible challenge by the IRS during an audit examination. The Company’s 2014 federal income tax return was subsequently selected for examination by the IRS. In 2018, the Company increased its income tax reserve provision to $4.1 million. During the first quarter of 2019, the Company agreed to certain modifications of its accounting method for expenditures that qualify as deductible repairs and the IRS concluded its audit of the Company’s 2014 federal income tax return. The modifications also impacted the Company’s filed 2015, 2016 and 2017 federal income tax returns. In 2019, the Company paid $0.8 million in income taxes and $0.1 million in interest in connection with the conclusion and closing of the 2014 and 2015 tax return audits and reduced its income tax reserve provision and interest expense liability to $3.1 million and $0.2 million, respectively. The IRS is currently examining the 2016 and 2017 tax returns to determine the impact of the modifications on those filings and pending completion of those examinations, the final tax liability could be different than the recorded reserve provision.
