Debt

On November 21, 2011, the Company terminated its credit facility agreement originally signed on December 20, 2006. Also, on November 21, 2011, the Company entered into a new agreement with a consortium of lenders to provide up to $150.0 million of financing to the Company through a five-year, unsecured revolving credit facility (the "Credit Facility") expiring on November 21, 2016. The agreement contains an expansion feature to increase the total financing available under the Credit Facility by up to $75.0 million to an aggregate of $225.0 million. Such increased financing would be provided by one or more existing Credit Facility lending institutions, subject to the approval of the lending banks, and/or in combination with one or more new lending institutions, subject to the approval of the Credit Facility's administrative agent.

As of March 31, 2012 and December 31, 2011, there were no outstanding borrowings under the Credit Facility. Interest paid during the three-month periods ended March 31, 2012, and 2011, was less than $0.1 million and $0.2 million, respectively.
