{a) In accordance with Subtopic 820-10, certain investments that were measured at fair value using the net asset value
per share (or its equivalent) practical expedient have not been classified in the fair value hierarchy. The fair value
amounts presented in this table are intended to permit reconciliation of the fair value hierarchy to the amounts
presented in the statements of assets available for benefits of the Plans.

Level 1: Based on quoted prices in active markets for identical assets.
Level 2: Based on significant observable inputs.
Level 3: Based on significant unobservable inputs.

The following table summarizes investments at fair value based on NAV per share as of
December 31, 2020 and 2019, respectively:

In order to satisfy the minimum funding requirements of the Employee Retirement Income
Security Act of 1974, applicable to defined benefit pension plans, the Company anticipates it
will contribute approximately $1.4 million to the DB Plan in 2021.

The following maximum benefit payments, which reflect expected future service, as appro-
priate, are expected to be paid in the years indicated:

Because the Company is subject to regulation in the state in which it operates, we are
required to maintain our accounts in accordance with the regulatory authority’s rules and
regulations. In those instances, we follow the guidance of ASC Topic 980 (“Regulated
Operations”). Based on prior regulatory practice, we recorded underfunded DB Plan and
OPEB Plan obligations as a regulatory asset, and we expect to recover those costs in rates
charged to customers.

Defined Contribution Plan

In addition to the defined benefit plan, the Company provides and maintains a defined
contribution plan covering substantially all employees. Under this plan, the Company
matches 100% of the first 3% of each participating employee’s salary contributed to the plan.
The matching employer’s contributions, recorded as operating expenses, were approximately
$272,000 and $278,000 for the years ended December 31, 2020 and 2019, respectively.

Financial Measurement and Fair Value of Financial Instruments

Management uses its best judgment in estimating the fair value of its financial instruments.
However, there are inherent weaknesses in any estimation technique. Therefore, for substan-
tially all financial instruments, the fair value estimates herein are not necessarily indicative of
the amounts that we could realize in a sales transaction for these instruments. The estimated
fair value amounts have been measured as of the period end and have not been reevaluated
or updated for purposes of these consolidated financial statements subsequent to those
respective dates.

A fair value hierarchy is used, which prioritizes the inputs to valuation methods used to measure
fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets
for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable
inputs (Level 3 measurements). The three levels of fair value hierarchy are as follows:

Level 1: Based on quoted prices in active markets for identical assets.
Level 2: Based on significant observable inputs.

Level 3: Based on significant unobservable inputs.

An asset or liability’s level within the fair value hierarchy is based on the lowest level of input
that is significant to the fair value measurement.

30

For assets and liabilities measured at fair value on a recurring basis, the fair value measure-
ment by levels within the fair value hierarchy used as of December 31, 2020 and 2019 were
as follows:

December 31, 2020

The carrying value of certain financial instruments included in the accompanying Consoli-
dated Balance Sheets, along with the related fair value, as of December 31, 2020 and 2019
was as follows:
2020 2019
Carrying Fair Carrying Fair
{in thousands) Value Value Value Value

Liabilities:
interest rate swap liability $ (460) $ (460) $ (353) $ (353)

The fair market value of the interest rate swap represents the estimated cost to terminate
this agreement as of December 31, 2020 and 2019 based upon the then-current interest rates
and the related credit risk.

The carrying values of our cash and cash equivalents, restricted cash, accounts receivable and
accounts payable approximate their fair values because of their short-term maturity dates.
The carrying value of CIAC approximates its fair value because it is expected that this is the
amount that will be recovered in future rates. The carrying values of lines of credit and long-
term debt approximate fair value, as interest rates approximate market rates.

City of Nashua, Public Works Division
Board of Public Works Meeting Date: May 25, 2022

David Boucher, Superintendent
Wastewater Department

Polymer

To approve Change Order #1 for the purchase of chemical Polymer from Polydyne of
Riceboro, GA in the amount of $39,000.00. Funding will be through: Department: 169
Wastewater; Fund: Wastewater; Account Classification: 61 Supplies & Materials.

Vendor quote
Polymer is a product used at the plant to coagulate sludge.

Periodically, the Facility has different companies come in and do bench testing to ensure
we are using the best polymer for the best price to meet our needs. Our current product
continues to perform well, producing a dry product that saves the City money in trucking
and disposal costs. The Polydyne products we are currently using are Clarifloc NE2180
for the screw presses and Clarifloc C-6266 for the belt filter presses.

The original fiscal year funding of $450,000 for the annual purchase of Polymer was
approved at the June 24, 2021 BPW Meeting and was based on historical usage. Due to
supply chain issues, the wastewater facility had to purchase smaller emergency loads at a
higher cost throughout the beginning of 2022 to ensure we would not run out of
chemicals and were able to maintain our treatment process. We are requesting additional
funding to complete the fiscal year.

Revenue from Contracts with Customers — Non-Regulated Entities

Revenue is recognized when control of the promised goods or services is transferred to
customers, in an amount that reflects the consideration we expect to be entitled to in
exchange for those goods or services.

Disaggregation of Revenue
For the years ended December 31, 2020 and 2019, revenue recognized for goods transferred
over time totaled $2,777,693 and $2,892,868, respectively.

For the year ended December 31, 2020, approximately 62% of revenues were from large-
contract customers, 21% of revenues were from small contract customers (con-ops), and 17%
revenues were from residential maintenance and other customers. For the year ended
December 31, 2019, approximately 59% of revenues were from large-contract customers,
20% of revenues were from small contract customers (con-ops), and 21% revenues were from
residential maintenance and other customers. In addition, substantially all of the Company's
contracts were service-related type contracts.

The Company has accumulated federal net operating losses. The federal tax benefit of the
cumulative net operating losses is approximately $4 million, begin to expire in 2033, and is
included in deferred income taxes in the Consolidated Balance Sheet as of December 31,
2020. Approximately 88% of the net operating losses are 100 percent available to be applied
to taxable income in future years and are not subject to the TCJA as they were generated
prior to the 2018 tax year. The enactment of the TCJA now limits the net operating loss shelter
to 80 percent of taxable income, for post-2017 tax year losses. The TCJA also provides for net
operating losses to be carried forward indefinitely instead of limited to 20 years, as is the case
for pre-2018 losses; however, carrybacks of these losses are no longer permitted.
Approximately 12% of the net operating losses were generated in 2019 and 2020 and

therefore are subject to the 80% limitation.

33

The Company has accumulated New Hampshire net operating losses. The New Hampshire tax
benefit of the cumulative net operating loss is approximately $1.4 million which begins to
expire in 2023 and is included in deferred income taxes in the Consolidated Balance Sheet as
of December 31, 2020.

As of December 31, 2020 and 2019, it is estimated that approximately $476,000 and
$476,000, respectively, of cumulative federal alternative minimum tax credits may be carried
forward indefinitely as a credit against our regular tax liability.

As of December 31, 2020 and 2019, the Company had New Hampshire Business Enterprise
Tax (“NHBET”) credits of approximately $960,000 and $1.1 million, respectively. NHBET
credits begin to expire in 2021. It is anticipated that these NHBET credits will not be fully
utilized before they expire; therefore, a valuation allowance has been recorded related to
these credits. The valuation allowance decreased by approximately $167,000 and increased
by approximately $126,000 in the years ended December 31, 2020 and 2019, respectively.

Investment tax credits resulting from utility plant additions are deferred and amortized. The
unamortized investment tax credits are being amortized through the year 2033.

The Company had a regulatory liability related to income taxes of approximately $9,918,000
and $9,930,000 as of December 31, 2020 and 2019, respectively. This represents the
estimated future reduction in revenues associated with deferred taxes which were collected
at rates higher than the currently enacted rates and the amortization of deferred investment
tax credits.

A review of the portfolio of uncertain tax positions was performed. In this regard, an
uncertain tax position represents the expected treatment of a tax position taken in a filed tax
return, or as planned to be taken in a future tax return, that has not been reflected in
measuring income tax expense for financial reporting purposes. As a result of this review, it
was determined that the Company had no material uncertain tax positions, and tax planning
strategies will be used, if required and when possible, to avoid the expiration of any future
net operating loss and/or tax credits.

The Company’s practice is to recognize interest and/or penalties related to income tax
matters in “Other, Net” in the Consolidated Statements of Income. We incurred no interest
in 2020 and 2019. We incurred no penalties during the years ended December 31, 2020 and
2019.
