Certain financial instruments, including derivatives, may be eligible for offset in the consolidated balance sheet and/or subject to master netting arrangements. The Company's derivative transactions with financial institution counterparties are generally executed under International Swaps and Derivative Association ("ISDA") master agreements which include "right of setoff" provisions. In such cases there is generally a legally enforceable right to offset recognized amounts and there may be an intention to settle such amounts on a net basis. Nonetheless, the Company does not generally offset financial instruments for financial reporting purposes.

Pursuant to the Company's agreements with certain of its derivative financial institution counterparties, the Company may receive collateral or post collateral, which may be in the form of cash or securities, based upon mark-to-mark positions.The Company has posted collateral with a market value of $30.5 million as of September 30, 2019.

Loans associated with a customer counterparty loan interest rate swap agreement may be subject to a make whole penalty upon termination of the agreement. The dollar amount of the make whole penalty varies based on the remaining term of the agreement and market rates at that time. The make whole penalty is secured by equity in the specific collateral securing the loan. The Company estimates the make whole penalty when determining if there is sufficient collateral to pay off both the potential make whole penalty and the outstanding loan balance at the origination of the loan. In the event of a customer default, the make whole penalty is capitalized into the existing loan balance; however, no guarantees can be made that the collateral will be sufficient to cover both the make whole provision and the outstanding loan balance at the time of foreclosure.
