Guarantees [Abstract]
Guarantees-Indemnifications to Officers and Directors	(16) Guarantees—Indemnifications to Officers and Directors The Company has entered into an updated form of indemnification agreement, which was approved in January 2012. The indemnification agreement to our directors and certain of our officers is to indemnify them to the extent permitted by law against any and all liabilities, costs, expenses, amounts paid in settlement and damages incurred by the directors as a result of any lawsuit, or any judicial, administrative or investigative proceeding in which the directors are sued as a result of their service as members of its Board of Directors. The form was intended to update the current form for our reincorporation into Delaware and general developments in corporate law since the adoption of our original form of indemnification agreement and was done as part of our ordinary course of corporate governance matters.
