TEXT-Fitch affirms Iowa Finance Authority SRF revs at 'AAA'

Nov 26 - Fitch Ratings affirms its 'AAA' rating on the following Iowa
Finance Authority's (IFA) outstanding bonds:

--$502.7 million state revolving fund (SRF) bonds, series 2010A, 2010B and 2011;
--$331.8 million SRF bonds, series 2003, 2007, 2008 and 2009.

The Rating Outlook is Stable.


The series 2010A, 2010B, and 2011 bonds (together the MTA bonds) are secured by
loan principal and interest amounts pledged under the restated and amended
master trust agreement (MTA), account investment earnings, and, if necessary,
amounts held in the equity fund.

The series 2003-2009 bonds (or the existing bonds) are secured by each series'
pledged loan principal and interest amounts, investment earnings, debt service
reserve funds, deficiency funds, and revenues pledged to the MTA bonds.


STRONG FINANCIAL STRUCTURE: The program's overcollateralization and significant
reserves provide enough credit enhancement to withstand loan defaults of up to
89% (the default tolerance) of the pool in the first four years of the bonds
life and up to 100% in both middle and last four-years. This is in excess of
Fitch's 'AAA' liability default hurdle of 59% as produced using Fitch's
Portfolio Stress Calculator (PSC), which is derived based on overall pool credit
quality as measured by the rating of underlying borrowers, size, loan term, and

ADEQUATE POOL CREDIT QUALITY: An estimated 60% of pledged borrowers are small,
non-rated entities. However, strong underlying loan provisions provide security
of loan principal from water, sewer, general obligation pledges, or some
combination of the three.

respect to the existing bonds only) and equity fund provide for
cross-collateralization, meaning surplus amounts in each respective fund
allocated to the clean water accounts can be used to cure shortfalls in drinking
water accounts and vice-versa.


Iowa's SRF program follows guidelines established by the Environmental
Protection Agency under the Drinking Water and Clean Water Acts, wherein federal
capitalization grants and a 20% state match are used to provide subsidized loans
to eligible borrowers. Such loans are used to provide below-market financing for
water pollution and drinking water infrastructure projects within the state.


With the issuance of the 2010 bonds, the indenture was amended and restated
allowing for all loan repayments to be pledged to the MTA instead of dedicated
loan repayments specifically securing each outstanding series of program bonds.
All future bonds are expected to be issued out of the amended and restated MTA
and secured by the program's open indenture.

IFA's scheduled borrower repayments derived from bond proceeds and direct loans
derived from the program's pledged equity funds, plus interest income (net
revenues), provide strong annual debt service coverage. Excess cash flow
coverage or overcollateralization after paying debt service is expected to be a
minimum of 1.25x.

In addition to pledged revenues, existing bonds are secured by a deficiency fund
held by the trustee. The deficiency fund is used to prevent any shortfalls of
debt service payable to the existing bonds only. After debt service is paid in
full, remaining amounts in the deficiency fund are transferred to the MTA equity
fund on each payment date. Amounts available in the equity fund provide
additional security for all outstanding bonds (both from the restated and
existing MTA).


The deficiency fund (with respect to the existing bonds only) and equity fund
provide for crosscollateralization, meaning amounts in each fund allocated to
clean water accounts can be used to cure shortfalls in drinking water accounts
and vice versa. This increases the diversity of the loan pool and lessens the
risk of any one borrower's default eroding reserve balances and threatening
bondholder payments. As of August 2012, the unencumbered equity fund balance
stood at approximately $70 million. Program reserves, which total approximately
$35 million, are primarily invested in fully collateralized investment
agreements, money market funds, and U.S. agency securities.


Senior or first lien loans are required to be covered by pledged net revenues of
at least 1.1x annual parity debt, while any junior lien loans must be covered by
1.05x maximum annual debt service. Senior lien loans account for more than 90%
of all program loans. MTA funds can be transferred out of the program, as long
as an officer's certificate report reflects that such withdrawals would not
cause the projected asset coverage ratio to drop below 1.2x.

Additional parity bonds can be issued provided that, after such issuance, all-in
debt service coverage is at least 1.05x. In calculating such coverage, all
expected pledged revenues, funds,
accounts and subaccounts can be used, excluding amounts in the rebate fund.
Given IFA's stated intent, Fitch expects that IFA will sustain coverage levels
and borrower loan default
tolerance levels that will continue to pass Fitch's 'AAA' stress test scenarios.


The combined MTA consists of approximately 420 obligors. Although there are a
large number of individual borrowers, concentration is moderate for a municipal
bond pool, with the top 10 representing approximately 44% of the aggregate loan
pool. Single-obligor concentration is also moderate, with the largest obligor,
the Wastewater Reclamation Authority, representing 12% of the total pledged loan

Fitch estimates that approximately 32% of the pool exhibits investment-grade
characteristics. Loan provisions are strong with virtually all loan principal
secured by water and/or wastewater revenue pledges or general obligation
pledges, the majority of which are senior lien.


IFA is ultimately responsible for the arrangement of financing for borrowers.
This includes the review, processing, underwriting, and approval of
program-eligible loans that meet the minimum coverage requirements. The IFA
board consists of nine members appointed by the governor, with the approval of
two-thirds of the members of the state Senate.

Management of the program is supplemented by the state Department of Natural
Resources (DNR). DNR is responsible for performing ongoing SRF program
operations, monitoring project progress, and providing technical support to
participants. DNR provides technical assistance to loan participants and
monitors all projects to ensure conformity with SRF and DNR rules and
