The Company exchanges variation margin for swaps based upon daily changes in fair value. As a result of amendments to rules governing certain central clearing activities, the exchange of variation margin is treated as a legal settlement of the exposure under the swap contract. Previously such payments were treated as cash collateral pledged against the exposure under the swap contract. Accordingly, the Company accounted for the receipt or payment of variation margin as a direct reduction to or increase in the carrying value of the interest rate swap asset or liability on the accompanying consolidated balance sheets.</span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div>
