ITEM 1.01. Entry into a Material Definitive Agreement.

On May 11, 2007, a single series of mortgage; pass-through certificates, entitled Wachovia Bank Commercial Mortgage Trust, Commercial Mortgage Pass-Through Certificates, Series 2007-C31 (the “Certificates”), was issued pursuant to a pooling and servicing agreement (the “Pooling Agreement”) attached hereto as Exhibit 4.1, and dated as of May 1, 2007, among Wachovia Commercial Mortgage Securities, Inc., as depositor (the “Registrant”), Wachovia Bank, National Association, as master servicer, LNR Partners, Inc., as special servicer, and Wells Fargo Bank, N.A., as trustee. The Certificates consist of thirty-two classes (each, a “Class”) of Certificates, fourteen of which Classes are designated as the “Class A-l Certificates”, the “Class A-2 Certificates”, the “Class A-3 Certificates”, the “Class A-PB Certificates”, the “Class A-4 Certificates”, the “Class A-5 Certificates”, the “Class A-1A Certificates”, the “Class A-M Certificates”, the “Class A-J Certificates”, the “Class B Certificates”, the “Class C Certificates”, the “Class D Certificates”, the “Class E Certificates” and the “Class F Certificates” (collectively, the “Offered Certificates”); and eighteen of which Classes are designated as the “Class A-5FL Certificates”, the “Class G Certificates”, the “Class H Certificates”, the “Class J Certificates”, the “Class K Certificates”, the “Class L Certificates”, the “Class M Certificates”, the “Class N Certificates”, the “Class O Certificates”, the “Class P Certificates”, the “Class Q Certificates”, the “Class S Certificates”, the “Class T Certificates”, the “Class U Certificates”, the “Class IO Certificates”, the “Class R-I Certificates”, the “Class R-II Certificates” and the “Class Z Certificates” (collectively, the “Private Certificates”). The Certificates evidence in the aggregate the entire beneficial ownership interest in a trust fund (the “Trust Fund”) consisting primarily of one hundred and eighty-nine (189) commercial mortgage loans (the “Mortgage Loans”) having an aggregate Cut-Off Date Pool Balance of approximately $4,899,751,000. Each Mortgage Loan is secured by a mortgage lien on a fee or leasehold interest in an income producing property. Certain of the Mortgage Loans (the “Wachovia Loans”) were acquired by the Registrant from Wachovia Bank, National Association (“Wachovia”) pursuant to a mortgage loan purchase agreement, dated as of May 1, 2007, between the Registrant and Wachovia. Certain of the Mortgage Loans were acquired by the Registrant from Nomura Credit & Capital, Inc.

Certain of the Mortgage Loans (the “Barclays Loans”) were acquired by the Registrant from Barclays Capital Real Estate, Inc. (“Barclays”) pursuant to a mortgage loan purchase agreement, dated as of May 1, 2007, between the Registrant and Barclays. The source of funds for payment of the purchase price for the Mortgage Loans paid by the Registrant to Wachovia was derived from (i) the sale of the Offered Certificates by the Registrant to Wachovia Capital Markets, LLC (“Wachovia Securities”), Wachovia Commercial Mortgage Securities, Inc., Wachovia Bank, National Association, Barclays Capital Inc. (“Barclays Capital”), Credit Suisse Securities (USA) LLC (“Credit Suisse”) and Goldman, Sachs & Co., (“Goldman”, together with Wachovia Securities, Barclays Capital and Credit Suisse, the “Underwriters”) pursuant to the underwriting agreement (the “Underwriting Agreement”), dated May 11, 2007, and (ii) a Certificate Purchase Agreement, dated May 11, 2007, among the Registrant, Wachovia and Wachovia Securities (pertaining to the Class A-5FL, Class G, Class H, Class J, Class K, Class L, Class M, Class N, Class O, Class P, Class Q, Class S, Class T, Class U and Class IO Certificates). The Registrant is a wholly-owned limited purpose finance subsidiary of Wachovia. On May 1, 2007 the Registrant transferred the Mortgage Loans to the Trust Fund pursuant to the Pooling Agreement. The consideration received by the Registrant in exchange for such transfer consisted of the Certificates. The Offered Certificates and the Mortgage Loans are more particularly described in the Prospectus, dated October 19, 2006, and the Prospectus Supplement, dated May 11, 2007 as previously filed with the Securities and Exchange Commission pursuant to Rule 424(b)(5).
