Subsequent Events [Abstract]
Subsequent Event	Subsequent Event Subsequent to September 30, 2015, we executed a second amendment (the Second Amendment) to our Secured Revolving Credit Facility. The Second Amendment, among other things, extends the termination date of the Facility to January 15, 2018 and increases its capacity from $130.0 million to $145.0 million. The Facility, which also allows us to issue letters of credit against the undrawn capacity, will continue to be with three lenders.
