Leases [Abstract]
Build-to-Suit Lease	Build-to-Suit Lease On October 3, 2014, we entered into a 15-year lease agreement for a build-to-suit facility related to the design and construction of a new campus in Long Beach, California. Under the agreement, we have retained substantially all of the construction risk. Therefore, for accounting purposes, we are considered the owner during the construction period and establish assets and liabilities for the estimated construction costs incurred to the extent we are involved in the construction of structural improvements or take construction risk prior to the lease commencement. Although we are the owner during the construction period, we do not own the underlying land. Therefore, we have an imputed operating lease expense related to our use of the land that will be recognized from the time we entered into the agreement through the initial lease term.

The entire disclosure for lessee entity's leasing arrangements including, but not limited to, all of the following: (a.) The basis on which contingent rental payments are determined, (b.) The existence and terms of renewal or purchase options and escalation clauses, (c.) Restrictions imposed by lease agreements, such as those concerning dividends, additional debt, and further leasing.
