OREANDA-NEWS. Fitch Ratings has upgraded six and affirmed one class of MACH ONE 2004-1, LLC (MACH ONE) as a result of increased credit enhancement to the notes from principal paydowns. A complete list of rating actions follows at the end of this release.

KEY RATING DRIVERS

Since the last rating action in October 2014, the class F and G notes have paid-in-full and the class H notes have received \\$8.9 million in paydowns. Over this period, none of the collateral has been downgraded and 36.5% has been upgraded. Currently, 64% of the portfolio has a Fitch derived rating below investment grade and 11.8% has a rating in the 'CCC' category and below, compared to 43.8% and 8.9%, respectively, at the last rating action. In addition, approximately 23% of the pool has a Fitch derived rating of 'AAA'. As of the Sept. 30, 2015 payment date, the class H through N notes are current on interest while the class O notes are experiencing interest shortfalls. Since issuance the transaction has experienced approximately \\$538 million in paydowns.

This transaction was analyzed under the framework described in the report 'Global Rating Criteria for Structured Finance CDOs' using the Portfolio Credit Model (PCM) for projecting future default levels for the underlying portfolio. Fitch also analyzed the structure's sensitivity to the assets that are distressed, experiencing interest shortfalls, and those with near-term maturities. Additionally, a deterministic analysis was performed where the recovery estimate on the distressed collateral was modeled in accordance with the principal waterfall. An asset by asset analysis was then performed for the remaining assets to determine the collateral coverage for the remaining liabilities. Based on the analysis, classes H through M pass at or above the assigned ratings. The ratings reflect these results as well as the risk of adverse selection as the portfolio continues to amortize.

For the class N notes, Fitch analyzed the class' sensitivity to the default of the distressed assets ('CCC' and below). Given the probability of default of the underlying assets and the expected recovery prospects upon default (with increasing credit enhancement due to paydown), the class N notes have been upgraded to 'CCCsf', indicating that default is possible. The class O notes have been affirmed at 'Dsf' due to incurred principal losses (approximately \\$2.6 million since the last rating action).

The Stable Outlook on the class H and K through M notes and Positive Outlook on class J reflects Fitch's expectation that the transaction will continue to delever and anticipated recoveries from the distressed collateral.

RATING SENSITIVITIES

In addition to the sensitivities discussed above, additional negative migration and defaults beyond those projected by SF PCM as well as increasing concentration of weaker credit quality assets could lead to downgrades for the more junior classes. The senior notes are expected to continue to amortize as 36% of the collateral are senior positions in their respective underlying transactions.
