OREANDA-NEWS. Fitch Ratings affirms the three remaining rated classes of Credit Suisse First Boston Mortgage Securities Corp., series 2001-CK1 (CSFB 2001-CK1) commercial mortgage pass-through certificates. A detailed list of rating actions follows at the end of this release.

KEY RATING DRIVERS

The affirmations are due to the stable performance of the one remaining asset which remains current but continues to underperform.

The remaining loan in the pool is a 160,509 square foot (sf) office property located in Raleigh, NC (61.7%). The loan transferred to the special servicer in January 2011 due to maturity default. The loan was transferred back to the master servicer after the borrower's bankruptcy plan was approved and the loan was modified. The sponsor is working to raise occupancy by aggressively marketing the building to prospective tenants. The loan was extended and is now scheduled to mature in October 2016. Current occupancy is 67%, which is an improvement from 64% reported in 2014.

As of the February 2015 distribution date, the pool's aggregate principal balance has been reduced by 98.4% to \$15.8 million from \$997.1 million at issuance. Interest shortfalls total \$3.66 million and affect classes O through K. The pool has experienced \$38.6 million (3.87% of the original pool balance) in realized losses to date.

RATINGS SENSITIVITIES

The Rating Outlook of class J is Stable as no rating changes are expected. Although credit enhancement is high, the loan continues to underperform and may not be able to refinance at the extended maturity date. Class K could be subject to a downgrade to 'Dsf' if losses are incurred if the loan defaults at maturity.

Fitch affirms the following class as indicated:

--\$7 million class J at 'B-sf', Outlook Stable;
--\$7.5 million class K at 'Csf', RE to 90% from 65%;
--\$1.3 million class L at 'Dsf', RE 0%.

Fitch does not rate classes M, N, and O certificates and previously withdrew the ratings on the A-X and A-CP notes. Classes A-1 through H have paid in full.
