TRANSACTION SUMMARY

Arch Street CLO, Ltd. (the issuer) and Arch Street CLO, LLC (the co-issuer) comprise an arbitrage cash flow collateralized loan obligation (CLO) that will be managed by NewStar Capital LLC. Net proceeds from the issuance of the secured and subordinated notes will be used to purchase a portfolio of approximately $400 million primarily senior secured leveraged loans. The CLO will have an approximately four-year reinvestment period and two-year noncall period.

KEY RATING DRIVERS

Sufficient Credit Enhancement: Credit enhancement (CE) available to the notes, in addition to excess spread, is sufficient to protect against portfolio default and recovery rate projections in the respective rating stress scenarios. The degree of CE available to class A, C and D notes are in line with the average CE of notes at the same rating level in recent CLO issuances. Class X notes are expected to be paid in full from the application of interest proceeds on the first or second payment date.

'B+/B' Asset Quality: The average credit quality of the indicative portfolio is 'B+/B', which is comparable to recent Fitch-rated CLOs. Issuers rated in the 'B' rating category denote a highly speculative credit quality; however, in Fitch's opinion, each class of rated notes is projected to be sufficiently robust against default rates, in line with its applicable rating stress.

Strong Recovery Expectations: The indicative portfolio consists of 98.7% first lien senior secured loans. Approximately 95.3% of the indicative portfolio has either strong recovery prospects or a Fitch-assigned Recovery Rating of 'RR2' or higher, and the base case recovery assumption is 80.7%. In determining the ratings for each class of rated notes, Fitch stressed the indicative portfolio by assuming a higher portfolio concentration of assets with lower recovery prospects and further reduced recovery assumptions for higher rating stress assumptions. The analysis of class X, A, C and D notes assumed recovery rates of 39.4%, 39.4%, 53.6% and 59.7% for their respective rating scenario.

RATING SENSITIVITIES

Fitch evaluated the structure's sensitivity to the potential variability of key model assumptions,

Including decreases in recovery rates and increases in default rates or correlation. Fitch expects

The class X and A notes to remain investment grade and class C and D notes to remain within two rating categories of their assigned ratings, even under the most extreme sensitivity scenarios. Results under these sensitivity scenarios ranged between 'A+sf' and 'AAAsf' for the class X notes, 'A+sf' and 'AAAsf' for the class A notes, 'BB+sf' and 'A+sf' for the class C notes and 'B-sf' and 'BBB+sf' for the class D notes.

Key Rating Drivers and Rating Sensitivities are further described in the accompanying new issue report, which will be available shortly to investor's on Fitch's website at 'fitchratings. com'.
