The Company entered into an interest rate swap agreement in 2012 to reduce its exposure to market risks from changing interest rates, exchanges the variable rate to fixed interest rate payments of 2.47%. The exchange-traded swap is valued on a recurring basis using quoted market prices and was classified within Level 2 of the fair value hierarchy which includes significant other observable inputs because the exchange is not deemed an active market. The swap agreement is a fair value hedge. The derivative mark to market was $0.1 million as of January 31, 2015 and January 31, 2014, respectively. This was included in other long-term liabilities on the consolidated balance sheets.
