The York County Industrial Development Authority Series 2006 bonds are subject to optional redemption provisions that allow the Company to redeem all or a portion of the bonds on or after October 1, 2016. The Company may refinance these bonds at some time to take advantage of lower interest rates.

In the second quarter of 2016, the Company renewed its $13,000 and $11,000 committed lines of credit and extended the maturity date of each to May 2018. In addition, the Company renewed its third line of credit, increasing the committed amount from $5,000 to $7,500, lowering the interest rate from LIBOR plus 1.50% to LIBOR plus 1.25%, and extending the maturity date to June 2017.

Subsequent to June 30, 2016, the Company entered into an agreement with a fourth bank for a $10,000 unsecured committed line of credit at an interest rate of LIBOR plus 1.20% maturing in July 2017.
