The premium finance loans represent short-term loans which we make to many of our brokerage related clients and other non-brokerage clients to finance their premiums paid to insurance carriers. These premium finance loans are primarily generated by the Crombie/OAMPS operations which were acquired on June 16, 2014. Financing receivables are carried at amortized cost. Given that these receivables are collateralized, carry a fairly rapid delinquency period of only seven days post payment date, and that contractually the underlying insurance policies will be cancelled within one month of the payment due date, there historically has been a minimal risk of not receiving payment and therefore we do not maintain any significant allowance for losses against this balance.
