The Company is subject to interest rate risk related to the variable rate debt. When interest rates increase, interest expense would increase. Conversely, when interest rates decrease, interest expense would also decrease.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:9pt;"&gt;&lt;font style="font-family:inherit;font-size:9pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:9pt;"&gt;&lt;font style="font-family:inherit;font-size:9pt;"&gt;In order to manage fluctuations in cash flows resulting from interest rate risk attributable to changes in the benchmark interest rates, the Company entered into &lt;/font&gt;&lt;font style="font-family:inherit;font-size:9pt;color:#000000;text-decoration:none;"&gt;3&lt;/font&gt;&lt;font style="font-family:inherit;font-size:9pt;"&gt;-year interest rate swap agreements with a total notional amount of &lt;/font&gt;&lt;font style="font-family:inherit;font-size:9pt;color:#000000;text-decoration:none;"&gt;$500 million&lt;/font&gt;&lt;font style="font-family:inherit;font-size:9pt;"&gt; to fix the variable  LIBOR rate on the Company's term loan to &lt;/font&gt;&lt;font style="font-family:inherit;font-size:9pt;color:#000000;text-decoration:none;"&gt;0.52%&lt;/font&gt;&lt;font style="font-family:inherit;font-size:9pt;"&gt;, resulting in an effective rate of &lt;/font&gt;&lt;font style="font-family:inherit;font-size:9pt;color:#000000;text-decoration:none;"&gt;2.14%&lt;/font&gt;&lt;font style="font-family:inherit;font-size:9pt;"&gt; after adding the &lt;/font&gt;&lt;font style="font-family:inherit;font-size:9pt;color:#000000;text-decoration:none;"&gt;1.625%&lt;/font&gt;&lt;font style="font-family:inherit;font-size:9pt;"&gt; margin per the 2012 Credit Agreement, as amended. Under the interest rate swap, the Company receives LIBOR-based variable interest rate payments and makes fixed interest rate payments, thereby creating the equivalent to fixed-rate debt with respect to the notional amount of such swap agreements. These interest rate contract derivative instruments were designated as cash flow hedges upon inception in September 2012.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:9pt;"&gt;&lt;font style="font-family:inherit;font-size:9pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:9pt;"&gt;&lt;font style="font-family:inherit;font-size:9pt;"&gt;The Company assesses interest rate cash flow risk by continually identifying and monitoring changes in interest rate exposures that may adversely impact expected future cash flows and by evaluating hedging opportunities. The Company does not enter into derivative instruments for any purpose other than hedging identified exposures. That is, the Company does not speculate using derivative instruments and has not designated any instruments as fair value hedges or hedges of the foreign currency exposure of a net investment in foreign operations.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:9pt;"&gt;&lt;font style="font-family:inherit;font-size:9pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:9pt;"&gt;&lt;font style="font-family:inherit;font-size:9pt;"&gt;The fair value of the interest rate swap liability as of &lt;/font&gt;&lt;font style="font-family:inherit;font-size:9pt;color:#000000;text-decoration:none;"&gt;June&amp;#160;30, 2013&lt;/font&gt;&lt;font style="font-family:inherit;font-size:9pt;"&gt; was &lt;/font&gt;&lt;font style="font-family:inherit;font-size:9pt;color:#000000;text-decoration:none;"&gt;$0.9 million&lt;/font&gt;&lt;font style="font-family:inherit;font-size:9pt;"&gt;.

This expectation is based on the expected timing of the occurrence of the hedged forecasted transactions and assumes the current LIBOR rate will remain consistent. Fluctuations in the market LIBOR rate will have an impact on the amount of expense reclassified from accumulated other comprehensive income to interest expense, as well as the overall fair value of the derivative instrument.&lt;/font&gt;&lt;/div&gt;&lt;/div&gt;</NonNumbericText><FootnoteIndexer /><CurrencyCode /><CurrencySymbol /><IsIndependantCurrency>false</IsIndependantCurrency><ShowCurrencySymbol>false</ShowCurrencySymbol><DisplayDateInUSFormat>false</DisplayDateInUSFormat></Cell></Cells><ElementDataType>nonnum:textBlockItemType</ElementDataType><SimpleDataType>na</SimpleDataType><ElementDefenition>The entire disclosure for the entity's entire derivative instruments and hedging activities.
