Leases [Abstract]
Financing Liability	Financing Liability In April 2010, the Company modified the terms of the building lease, i.e., those which previously resulted in the Company being considered the owner of the building for accounting purposes. Under the terms of the modified lease, the letter of credit that constituted continuing involvement was replaced with a cash security deposit. This provision allowed the Company to qualify for sale-leaseback accounting and to begin accounting for the lease as an operating lease. In connection with the sale-leaseback of the building, the Company wrote off the remaining asset value of the building, related accumulated depreciation and the financing liability. As a result, the Company recorded a gain on sale-leaseback of $1.7 million.
