On June 25, 2014, we entered into an amendment to our unsecured, syndicated revolving credit agreement, which increased the borrowing capacity from $500,000 to $600,000, extended the maturity date from July 1, 2018 to July 1, 2019, increased the swingline subfacility from $65,000 to $90,000 and modified certain definitions. At June 30, 2014 and December 31, 2013, $348,787 and $230,044 was outstanding under the revolving credit agreement, respectively. The revolving credit agreement contains customary affirmative and negative covenants, including financial covenants with respect to consolidated leverage and interest coverage ratios, and other customary restrictions. We believe we were in compliance with all covenants at June 30, 2014.
