We have the ability to increase the total commitment of our Revolving Credit Facility by up to $200.0 million for a total facility size of up to $500.0 million, subject to receiving increased commitments from lenders and to the satisfaction of certain conditions. The Revolving Credit Facility includes a $25.0 million sub-limit for standby letters of credit and a $10.0 million sub-limit for swing line loans.

The applicable margin will vary based on our Consolidated Total Leverage Ratio, as defined in the Revolving Credit Facility.
