Item 8.01.Other Events. On October 28, 2008, First Midwest Bancorp, Inc. ("FMBI" or the "Company") filed an application with the U.S. Department of the Treasury ("Treasury") to participate in the voluntary Capital Purchase Program ("CPP"). The CPP offers all qualifying financial institutions that are approved by the Treasury the opportunity to issue and sell senior perpetual preferred stock, along with warrants to purchase common stock, to the Treasury. FMBI has received preliminary approval from the Treasury to participate in the CPP, up to the program's maximum allowable amount of 3% of the Company's risk-weighted assets, or $193 million. A press release announcing the Treasury's preliminary approval of FMBI's CPP application is attached hereto as Exhibit 99.1. Upon participation, the proceeds would further bolster the Company's already well-capitalized regulatory total capital ratio as of September 30, 2008, which stood at 12.04%, some $132 million in excess of required levels, and would further strengthen FMBI's capital position. The Treasury initiated CPP under authority provided in the Emergency Economic Stabilization Act of 2008 ("EESA"). CPP is designed to attract broad participation by healthy institutions to stabilize the financial system. Additional information about EESA and CPP is available on the Treasury web site atwww.treas.gov/initiatives/eesa. The information contained in this Current Report on Form 8-K is being furnished to, and shall not be deemed "filed" with, the Securities and Exchange Commission. |
