Realized losses covered by the loss sharing agreement include loan contractual balances (and related unfunded commitments that were acquired), accrued interest on loans for up to 90 days, the book value of foreclosed real estate acquired, and certain direct costs, less cash or other consideration received by Great Southern.

In addition to the loan and FDIC indemnification assets noted above, the acquisition consisted of other assets with a fair value of approximately $47.2 million, including $23.1 million of investment securities, $12.8 million of cash and cash equivalents, $2.2 million of foreclosed assets and $5.9 million of FHLB stock. Liabilities with a fair value of $444.0 million were also assumed, including $352.7 million of deposits, $74.6 million of FHLB advances, $10.0 million of borrowings from the Federal Reserve Bank and $3.2 million of repurchase agreements with a commercial bank. A customer-related core deposit intangible asset of $2.2 million was also recorded. In addition to the excess of liabilities over assets, the Bank received approximately $131.3 million in cash from the FDIC and entered into the loss sharing agreement with the FDIC.
