Chemical Financial Corporation Identifies Fraudulent Loan Transaction

Company Release - 9/8/2008 7:44 AM ET

MIDLAND, Mich., Sept. 8, 2008 (GLOBE NEWSWIRE) -- Chemical Financial Corporation (Nasdaq:CHFC) today announced that it has identified a fraudulent commercial loan transaction related to a single borrower with an aggregate outstanding loan balance of $10.5 million. While the borrowings are secured by collateral, the Company has currently determined that due to the irregularities involved the collateral may have limited value. As a result, Chemical Financial Corporation will incur an after-tax charge of $7.2 million, or $0.30 per share, to third quarter 2008 earnings for the entire $10.5 million exposure.

"We are extremely disappointed by this situation, but it is important to note that this is a single, isolated incident of fraud perpetuated by one borrower and we do not believe that it is reflective of the strength and character of our overall commercial loan portfolio. Chemical Financial Corporation remains financially strong and very well capitalized," said David B. Ramaker, Chairman, President and Chief Executive Officer.

The asset impairment was discovered on September 3, 2008 after an ongoing investigation into irregularities involving one of the Company's long-term client relationships, coupled with information arising from an ongoing federal government investigation into the client. "It appears that the client intentionally made inaccurate, misleading and potentially illegal representations about its financial condition and the source of repayment for a significant line of credit. Based upon our initial investigation, it also appears that this client and some of its key officers intentionally engaged in a pattern of misleading, deceptive and potentially illegal practices involving misrepresentations of material aspects of the client's financial position," said Ramaker.

"We intend to vigorously pursue all reasonable avenues of recovery available to us. At this time, due to the complex nature of the transaction and extent of legal claims currently outstanding against this client, an estimate of recovery cannot be determined. At this stage of the investigation, no Chemical Financial Corporation personnel were involved in these fraudulent dealings," said Ramaker.

Chemical Financial Corporation is the third-largest bank holding company headquartered in Michigan. The Company operates through a single subsidiary bank, Chemical Bank, with 129 banking offices spread over 31 counties in the lower peninsula of Michigan. At June 30, 2008, the Company had total assets of $3.74 billion. Chemical Financial Corporation common stock trades on The NASDAQ Stock Market under the symbol CHFC and is one of the issues comprising the NASDAQ Global Select Market.
