Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions (see General Instruction A.2. below):

SVB Financial Group (the “Company”) is filing this Current Report on Form 8-K to update its historical financial statements included in its Annual Report on Form 10-K for the year ended December 31, 2009 (“2009 10-K”), to reflect, for all periods presented, a reorganization of the Company’s operating segments effective January 1, 2010. This report is issued for the purpose of incorporating the contents of this report in the Registration Statement on Form S-3 which we intend to file substantially concurrently herewith. Under Securities and Exchange Commission (the “SEC”) guidance, the revised segment financial reporting required by Accounting Standards Codification 280 should be provided for previously-issued financial statements included in the Company’s 2009 10-K, if those financial statements are incorporated by reference in filings with the SEC made under the Securities Act of 1933, as amended, even though those financial statements related to periods prior to the revised segment financial reporting.

Reorganization of Operating Segments

The reorganization of the Company’s operating segments was the result of changing the way we monitor performance and the results of our business. We have reclassified all prior period segment information to conform to the current presentation of our reportable segments. The segment reorganization did not change the Company’s previously reported consolidated financial position, results of operations or stockholders’ equity.

This report amends the following items included in the Company’s 2009 10-K:

This report does not change any information contained in any other item of the Company’s 2009 10-K as originally filed on March 1, 2010. This report does not reflect events that have occurred after the original filing date of the 2009 10-K, except as described above. The revised Management’s Discussion and Analysis of Financial Condition and Results of Operations and Financial Statements and Supplementary Data for the years ended December 31, 2009, 2008, and 2007 are incorporated by reference in this Item 8.01 and are attached to this current report on Form 8-K as Exhibit 99.1. This report should be read in conjunction with our 2009 10-K (except for Items 7 and 8 of Part II, which are contained in this report).

(d) Exhibits.
