Fitch Ratings assigns the following rating and Rating Outlook to Fannie Mae's second risk transfer transaction, Connecticut Avenue Securities, series 2014-C01:

--$375,000,000 class M-1 notes 'BBB-sf'; Outlook Stable.

The following classes will not be rated by Fitch:

--$28,429,457,323 class A-H reference tranche;

--$20,667,705 class M-1H reference tranche;

--$375,000,000 class M-2 notes;

--$20,667,705 class M-2H reference tranche;

--$87,926,156 class B-H reference tranche.

The 'BBB-sf' rating for the M-1 notes reflects the 1.65% subordination provided by the 1.35% class M-2 notes and the non-offered 0.30% B-H reference tranche. The notes are general senior unsecured obligations of Fannie Mae (rated 'AAA' on Negative Watch by Fitch) subject to the credit and principal payment risk of a pool of certain residential mortgage loans held in various Fannie Mae-guaranteed mortgage-backed securities (MBS).

Connecticut Avenue Securities, series 2014-C01 (CAS 2014-C01) is Fannie Mae's second risk transfer transaction issued as part of the Federal Housing Finance Agency's Conservatorship Strategic Plan for 2013 - 2017 for each of the government sponsored enterprises (GSEs) to demonstrate the viability of multiple types of risk transfer transactions involving single-family mortgages.

The objective of the transaction is to transfer credit risk from Fannie Mae to private investors with respect to a $29 billion pool of mortgage loans currently held in previously issued MBS guaranteed by Fannie Mae where principal repayment of the notes is subject to the performance of a reference pool of mortgage loans. As loans become 180 days delinquent or other credit events occur, the outstanding principal balance of the debt notes will be reduced by a pre-defined, tiered loss severity percentage related to those credit events.

While the transaction structure simulates the behavior and credit risk of traditional RMBS mezzanine and subordinate securities, Fannie Mae will be responsible for making monthly payments of interest and principal to investors. Because of the counterparty dependence on Fannie Mae, Fitch's rating on the M-1 notes will be based on the lower of: the quality of the mortgage loan reference pool and credit enhancement available through subordination; and Fannie Mae's Issuer Default Rating. The M-1 notes will be issued as uncapped LIBOR-based floaters and will carry a 10-year legal final maturity.

KEY RATING DRIVERS

Sustainable Home Value Rising: Fitch's sustainable home price values increased for 48 of the top 50 metropolitan statistical areas (MSAs) between the second and third quarters of 2013 due to continued improvement in the economic indicators factored into Fitch's view. However, the Case Shiller home price index continued to increase at a faster pace than is supported by economic fundamentals, causing only 14 of the 50 MSAs to move closer to sustainable values. As a result, Fitch's market value decline assumption increased slightly over the prior transaction, raising its loss expectation to 1.65% for this reference pool from 1.60%. There was virtually no credit drift in the collateral attributes.

Fewer Due Diligence Findings: Compared to Fannie Mae's prior transaction, fewer findings in the due diligence review were noted. The findings are reflective of the improvements made to Fannie Mae's risk management and quality control processes, which have evolved over time, with the majority of the processes developed following the crisis and implemented prior to 2013. The findings also reflect the revised scope of the due diligence review to better reflect Fannie Mae's quality control process.

Improved Aggregator Platform: Based on a comprehensive review of the platform, Fitch believes that Fannie Mae has a robust lender quality assurance and loan quality control review platform in place. Fitch applied a modest reduction to its default expectations to account for the lower risk associated with the recent acquisitions.

Fixed-Loss Severity: One of the unique structural features of the transaction is a fixed-loss severity schedule that is tied to cumulative net credit events. If actual loan loss severity is above the set schedule, Fannie Mae absorbs the higher losses. Fitch views the fixed-loss severity positively as it reduces uncertainty that may be driven by future changes in Fannie Mae loss mitigation or loan modification policies. The fixed severity also offers investors greater protection against natural disaster events where properties are severely damaged and there is limited or no recourse to insurance.

Advantageous Payment Priority: The payment priority of the M-1 class will result in a shorter life and more stable credit enhancement than mezzanine classes in private-label (PL) RMBS, providing a relative credit advantage. Unlike PL mezzanine RMBS, which often do not receive a full pro rata share of the pool's unscheduled principal payment until year 10, the M-1 class can receive a full pro rata share of unscheduled principal immediately as long as a minimum credit enhancement level is maintained. Additionally, unlike PL mezzanine classes, which lose subordination over time due to scheduled principal payments to more junior classes, the M-2 and B-H classes will not receive any scheduled or unscheduled allocations until the M-1 is paid in full. The B-H class will not receive any scheduled or unscheduled principal allocations until the M-2 is paid in full.

10-Year Hard Maturity: The M-1 and M-2 notes benefit from a 10-year legal final maturity. As a result, any collateral losses on the reference pool that occur beyond year 10 are borne by Fannie Mae and do not affect the transaction. Fitch accounted for the 10-year hard maturity in its default analysis and applied a 10% reduction to its lifetime default expectations.

Rep and Warranty Gaps: While the loan defect risk for 2014-C01 is notably lower than for agency and non-agency mortgage pools securitized prior to 2009, Fitch believes the risk is greater for this transaction than for recently issued U.S. PL RMBS. Notably, neither Fannie Mae nor an independent third party will conduct loan file reviews for credit events and Fannie Mae will not conduct any reviews of loans from a seller once it has filed for bankruptcy. Fitch incorporated this risk into its analysis by treating all historical repurchases as if they were defaulted loans that were not repurchased. Consequently, the rating analysis includes an assumption that the loans will experience defect rates consistent with historical rates and that those defects will not be repurchased.

Solid Alignment of Interests: While the transaction is designed to transfer credit risk to private investors, Fitch believes the transaction benefits from solid alignment of interests. Fannie Mae will be retaining credit risk in the transaction by holding the senior reference tranche A-H, which has 3% of loss protection, as well as the first-loss B-H reference tranche, sized at 30bps. Fannie Mae is also retaining a 5.2% vertical slice/interest in the M-1 and M-2 tranches.

Limited Size and Scope of Third-Party Diligence: Only 608 of the loans eligible to be included in the reference pool were selected for review by a third-party diligence provider. Of the 608 loans, 359 were part of this transaction's reference pool. This sample selection was also limited to a population of 1,477 loans that had been previously reviewed by Fannie Mae. Furthermore, the third-party due diligence scope was limited to reflect Fannie Mae's post-close loan review for compliance. Fitch's review of Fannie Mae's risk management and quality control process/infrastructure, which has been significantly improved over the past several years, indicates a robust control environment that should minimize loan quality risk.

Special Hazard Leakage: Fitch believes the structure is vulnerable to special hazard risk as there is no consideration for payment disruptions related to natural disaster events in the credit event definition. As such, credit protection in the transaction may be eroded by natural disasters that may cause extended delinquencies (that may in part be allowed by disaster relief programs) but where borrowers ultimately cure. Fitch considered this risk in its analysis, conducted sensitivity analysis and found, based on prior observed performance in post-natural disaster events including Hurricane Katrina and the Northridge earthquake, the risk exposure is relatively low.

Receivership Risk Considered: Under the Federal Housing Finance Regulatory Reform Act, the Federal Housing Finance Agency (FHFA) must place Fannie Mae into receivership if it determines that Fannie Mae's assets are less than its obligations for longer than 60 days following the deadline of its SEC filing, as well as for other reasons. As receiver, FHFA could repudiate any contract entered into by Fannie Mae if it is determined that it would promote an orderly administration of Fannie Mae's affairs. Fitch believes that the U.S. government will continue to support Fannie Mae, which is reflected in its current rating of Fannie Mae. However, if at some point Fitch views the support as being reduced and receivership likely, the ratings of Fannie Mae could be downgraded and the M-1 notes rating affected.

RATING SENSITIVITIES

Fitch's analysis incorporates a sensitivity analysis to demonstrate how the ratings would react to steeper market value declines (MVDs) than assumed at the state or MSA level. The implied rating sensitivities are only an indication of some of the potential outcomes and do not consider other risk factors that the transaction may become exposed to or be considered in the surveillance of the transaction. Two sets of sensitivity analyses were conducted at the state and national level to assess the effect of higher MVDs for the subject pool.

Historical Economic Data Incorporated in sMVD Projections: In its analysis, Fitch considered placing a greater emphasis on recent economic performance in determining MVDs for the pool. While Fitch's current loan loss model looks to three years of historical data and one year of projections, this does not incorporate recent notable economic improvement. To reflect the more recent economic environment, a sensitivity analysis was performed using two years historical economic data and two years of projections.

California sMVDs: Roughly 30% of the pool is located in California, in areas with both high and low MVD projections. The MVD projections are key contributors to Fitch's default assessment of this pool. Fitch conducted sensitivity analysis assuming sMVDs were 5%, 10%, and 15% higher than that for California. The sensitivity analysis indicated an impact on ratings for the rated bond.

Additional Decline in sMVD at the National Level: This set of sensitivity analysis demonstrates how the rating would react to steeper MVDs at the national level. The analysis assumes MVDs of 5%, 10% and 15% in addition to the model-projected 31% at the 'BBB-sf' rating level for this pool. The analysis indicates a rating impact with a further 5% MVD from the current model projection with further rating migration for the additional 10% and 15% MVD assumptions.
