The decision isn’t “if” to spend, but “how”

The decision isn t if to spend, but how

“Government agencies spend more than $10 billion a year on energy —

while grappling with tightening budgets. Yet nearly one-third of the energy

used to run typical government buildings goes to waste.”

• Market alternative to a cash purchase or tax-exempt municipal bond issue

Agreement?

• Interest is exempt from federal taxation, allowing rates to be set lower than for

bonds, providing the municipality with significant cost savings

• Non-appropriation clause: municipal payment obligation terminates if it fails to

appropriate funds to make lease payments

• Municipality holds title to the leased equipment

Advantages include:

Fast, simple approval process

(as compared to issuing a bond referendum)

Reduced transaction costs

(most costs associated with bond financing are

eliminated)

(

Lower interest rates

(the interest income is tax exempt; the lessor passes these

savings to the municipality in the form of a lower interest rate)

Full financing

(covers all project costs; no down payment required; funding into an

escrow account ensures the municipality has deepest vendor discounts)

escrow account ensures the municipality has deepest vendor discounts)

No large capital outlay

(project costs paid for as they are incurred; helps local

governments and school districts manage their capital reserve fund balances)
