Cornerstone Community Bancorp (OTC Pink: CRSB) announced today the charge-offs of three related agricultural loans in the aggregate amount of $9.4 million due to the deteriorating financial condition of the borrowers. This represents 100% of the Company’s exposure. Although one of the loans is secured by certain equipment and all three loans have guarantors, any future recoveries cannot be reasonably predicted. As a result of these charge-offs, the Company recorded a $9.4 million provision for credit losses on loans.

With the exception of the credits mentioned above, overall credit quality remains solid in the loan portfolio. The bank continues to maintain a strong capital position that exceeds well-capitalized regulatory requirements.
