$267.5 million of asset-backed securities rated
New York, September 17, 2010 -- Moody's Investors Service has assigned a definitive rating of Aaa (sf)
to the notes issued by Arkansas Student Loan Authority, Student
Loan Asset-Backed Notes, Series 2010-1 ("ASLA 2010-1").
Issuer: Arkansas Student Loan Authority
$267,500,000 LIBOR Floating Rate Notes, rated
The ratings are based on the underlying collateral which consists of Federal
Family Education Loan Program (FFELP) student loans, which are indirectly
guaranteed by the U.S. Department of Education for a minimum
of 97% of defaulted principal and accrued interest; available
credit enhancement provided by the overcollateralization of the trust,
which has a starting parity level of approximately 106.75%,
and gross excess spread expected to average approximately 20 basis points
per annum; and liquidity support provided by a debt service reserve
account equal to 0.25% of the initial pool balance and a
capitalized interest account funded at $2 million at closing.
The expected net loss on the collateral pool underlying the ASLA 2010-1
transaction is 0.15%.
In rating securitizations backed by student loans originated under FFELP,
Moody's assesses both the liquidity and credit risk of the transaction.
The drivers that affect the performance of a transaction include defaults,
servicer guarantee rejection rates, voluntary prepayments,
basis risk, borrower benefit utilization, and the number of
borrowers in non-repayment status, such as deferment and
As part of our analysis to understand the risk of the underlying collateral,
we examine historical FFELP static pool performance data. To the
extent that performance data is available from a specific issuer,
that information is used to arrive at our cash flow assumptions for that
particular issuer. If an issuer's data are either limited or unavailable,
our assumptions are based on FFELP performance data received from other
participants. Although FFELP loans are a standardized asset,
we will assume additional volatility in certain assumptions for those
issuers that have limited or no data.
In addition, historical interest rates and spreads are analyzed
to evaluate the basis risk between the interest rate to which the bonds
are indexed and the interest rate to which the FFELP loans are indexed.
This historical data is used to derive an expected, or most likely,
outcome for each variable. These expected defaults, prepayments,
interest rates, and other assumptions are then stressed in accordance
with the rating categories requested by the issuer. Factors that
influence the stress levels include the availability of relevant issuer-specific
performance data, the seasoning of the loans, collateral concentrations
(school types, loan programs), the financial strength and
stability of the servicer, and the general economic environment.
Other Methodologies and factors that may have been considered in the process
of rating this issuer can also be found on Moody's website.
These stressed assumptions are then incorporated into a cash flow model
that takes into account the FFELP loan characteristics as well as structural
(e.g., starting parity, cash flow waterfall,
bond tranching, etc.) and pricing features of the transaction.
The cash flow model outputs are analyzed to determine whether the transaction
as structured by the issuer has sufficient credit protection to pay off
the bonds by their legal final maturity dates. We also analyze
the liquidity risk of the transaction given that borrowers can be in non-repayment
status while in school, grace, deferment or forbearance status,
and the transaction can experience delays in default reimbursement and
The most common form of basis risk in FFELP-backed student loan
transactions is CP-based assets paired with LIBOR-based
liabilities. The basis risk exists because all FFELP loans disbursed
after 2000 generate a CP-based yield, while the bond interest
rates are generally indexed to LIBOR. This CP-LIBOR risk
is accounted for and stressed through Moody's interest rate cash flow
assumptions which were updated on November 19, 2008. Unlike
a typical FFELP transaction, the underlying collateral in the ASLA
2010-1 transaction consists of approximately 10% of loans
that are indexed to T-bill. This creates a significant amount
of basis risk between T-Bill and Three-Month LIBOR.
The interest rate stress assumptions used for the T-bill and Three-Month
Spread Assumptions: Aaa -- 150 bps; Maturity
-- 130 bps;
Spike Assumptions: Aaa -- 330 bps; Maturity --
The interest rate spikes occur in the third and fourth quarter of year
1; the third and fourth quarter of year 5 and for the first 6 months
after the pool factor reaches 10%.
The V Score for this transaction is Medium, which is in line with
the Medium V Score assigned for the U.S. FFELP-Backed
LIBOR-Indexed ABS sector.
Moody's V Scores provide a relative assessment of the quality of available
credit information and the potential variability around the various inputs
to a rating determination. The V Score ranks transactions by the
potential for significant rating changes owing to uncertainty around the
assumptions due to data quality, historical performance, the
level of disclosure, transaction complexity, the modeling
and the transaction governance that underlie the ratings. V Scores
apply to the entire transaction (rather than individual tranches).
If the basis risk in our Aaa stressed assumptions were to increase by
5, 15 or 25 basis points, the initial model outputs for the
Class A notes are Aa1, Aa2, and A1, respectively.
Parameter Sensitivities are not intended to measure how the rating of
the security might migrate over time; rather they are designed to
provide a quantitative calculation of how the initial model output might
change if key input parameters used in the initial rating process differed.
The analysis assumes that the deal has not aged. Parameter Sensitivities
only reflect the ratings impact of each scenario from a quantitative/model-indicated
standpoint. Qualitative factors are also taken into consideration
in the rating process, so the actual ratings that would be assigned
in each case could vary from the information presented in the Parameter
