In connection with its mortgage banking activities, Mid Penn enters into commitments to originate certain fixed-rate residential mortgage loans for customers, also referred to as interest rate locks. In addition, Mid Penn enters into forward commitments for the future sales or purchases of mortgage-backed securities to or from third-party counterparties to hedge the effect of changes in interest rates on the values of both the interest rate locks and mortgage loans held for sale. Forward sales commitments may also be in the form of commitments to sell individual mortgage loans at a fixed price at a future date. The amount necessary to settle each interest rate lock is based on the price that secondary market investors would pay for loans with similar characteristics, including interest rate and term, as of the date fair value is measured.
