Fitch Ratings Affirms CSFB 2001-CK1

CHICAGO--(Business Wire)--
Fitch Ratings affirms Credit Suisse First Boston (CSFB) Mortgage
Securities Corp.'s commercial mortgage pass-through certificates,
series 2001-CK1, as follows:

--$461.8 million class A-3 at 'AAA';

--Interest-only class A-X at 'AAA';

--Interest-only class A-Y at 'AAA';

--Interest-only class A-CP at 'AAA';

--$42.9 million class B at 'AAA';

--$45.4 million class C at 'AAA';

--$12.6 million class D at 'AAA';

--$12.6 million class E at 'AAA';

--$20.2 million class F at 'AAA';

--$17.7 million class G at 'AA+';

--$17.5 million class H at 'A-';

--$27.4 million class J at 'BB+';

--$7.5 million class K at 'BB';

--$7.5 million class L at 'B+'.

Fitch does not rate classes M, N, and O. The class A-1 and A-2
certificates have paid in full.

The rating affirmations are the result of minimal reduction of the
pool collateral balance and stable performance since the last Fitch
rating action. As of the July 2008 distribution date, the pool has
paid down 29.7%, to $700.6 million from $997.1 million at issuance.
Forty-one loans (45.1%) have defeased since issuance.

Fitch has identified 15 loans (13.7%) as Fitch Loans of Concern,
which include two loans in special servicing (4.5%).

The largest specially serviced loan (3.1%) was originally a
portfolio of four cross-collateralized, cross-defaulted multifamily
buildings located in Texas and Indiana. The portfolio transferred to
special servicing in August 2006 due to technical default because of
weak performance and existence of significant deferred maintenance. Of
the three of the assets that are located in Texas (Houston, Arlington
and Amarillo), the Arlington and Amarillo properties have been sold.
The remaining property in Texas is currently 38% occupied and is being
marketed for sale. One property is located in Indianapolis, Indiana
and the special servicer is working to foreclose on this asset. Losses
on this specially serviced loan are anticipated to be fully absorbed
by the nonrated class O.

The second specially serviced loan (1.4%) is secured by two office
buildings in Clayton, MO. The loan is current and losses are not
expected at this time.

The largest loan in the pool, Stonewood Center Mall (10.5%),
maintains its investment grade shadow rating. The loan is secured by
the leasehold interest in a 929,792 square foot regional retail mall
in Downey, CA. As of March 2008, occupancy was 98% compared to 94% at
issuance and the anticipated repayment date is December 11, 2010.

There is minimal short-term maturity risk as no loans mature in
2008 and one loan (0.2%) matures in 2009. The majority of the
non-defeased loans (40.5%) mature in 2010 and 2011.
