HVAC Replacement Project
In February of 2019, the Engineering Firm SMRT was hired to
perform a complete assessment of the Nashua Police
Department’s HVAC System. Some of the highlights of their
assessment follow
The HVAC systems for the Police Station were designed in two
stages with the original part of the building designed in 1977
and a subsequent Addition Project in 1999
The 1977 design is based on water source heat pumps and
the 1999 design is based on Variable Air Volume System
The 1977 design incorporates a Pistol Range and a Fleet
Maintenance Garage
47 of the 49 existing heat pumps are charged with R22
refrigerant. This material will be unavailable in the year 2020
The Air-cooled Condensing Unit that cools the air prior to it
being introduced to the heat pumps has failed and has been
removed causing the heat pumps to be overworked
HVAC Replacement Project
All equipment controlling the Pistol Range is original to the
1977 building, in poor condition and beyond it’s useful life.
Range officers have recently been blood tested and showed
high lead levels due to the systems inefficiencies
The Fleet Maintenance Garage System is also all original to
the 1977 building. It is in poor condition and beyond it’s
useful life
The Variable Air Volume System is original to the 1999
addition
There are two main hot water pumps supplying hot water to
the addition and operate on a lead/standby fashion. One of
those pumps is not operating due to a faulty isolation valve
leaving the building with no backup system
Many of the components of this system are currently
working but are charged with R22 and will not be able to be
repaired if they fail
the entire balance in this account, which included $23.4 million of principal due on the bonds
being refunded, as well as approximately $375,000 of accrued interest due on these bonds,
was paid out to the holders of those debt instruments.
This restricted cash balance also consists of funds that resulted from the issuance of the
Series 2015A tax-exempt bonds in October of 2015, as notated and fully described in Note
10 of these audited financial statements. The refinance money proceeds, as described in Note
10, from that bond issuance are maintained in a separate restricted cash account, pending the
completion of the refinance of existing tax-exempt bonds on November 30, 2015, the date at
which the required 30-day notice period to bondholders has expired from the date of
notification after the close of the October 27, 2015 bond closing. As of November 27, 2015,
the entire balance in this account, which included $16.2 million of principal due on the bonds
being refunded, as well as approximately $165,000 of accrued interest due on these bonds,
was paid out to the holders of these debt instruments.
Investments — Bond Project Funds
As discussed above, approximately $17.2 million of monies from the 2014 and 2015
restricted cash bond project funds were invested in instruments of varying maturities through
the end of 2016. At maturity, these funds will be utilized to reimburse qualifying and eligible
capital project expenditures as they go “used and useful” throughout 2016.
The Company determines the appropriate classification of its investments in debt and equity
securities at the time of purchase and reevaluates such determinations at each balance-sheet
date. Debt securities are classified as held-to-maturity when the Company has the positive
intent and ability to hold the securities to maturity. Held-to-maturity securities are recorded
as either short-term or long-term on the consolidated balance sheet, based on contractual
maturity date and are stated at amortized cost.
The fair value of all securities is determined by quoted market prices. The estimated fair
value of securities for which there are no quoted market prices is based on similar types of
securities that are traded in the market.
Concentration of Credit Risks
Financial instruments that subject our Company to credit risk consist primarily of cash
(including cash equivalents and restricted cash) and accounts receivable. Cash balances are
invested in financial institutions insured by the Federal Deposit Insurance Corporation
(“FDIC”). At December 31, 2015 and 2014, the Company had approximately $9,200,000 and
$48,700,000 in excess of FDIC insured limits, respectively. Our accounts receivable balances
primarily represent amounts due from the residential, commercial and industrial customers of
our regulated water utility operations, as well as receivables from our Service Corporation
customers.
