COMMITMENTS AND CONTINGENCIES Lease Commitments We occupy three office buildings in San Jose, California where our corporate headquarters are located. We reference these office buildings as the Almaden Tower and the East and West Towers. We own the land and the East and West Tower buildings, and lease the Almaden Tower building.

If we purchase the building, the investment in the lease receivables may be credited against the purchase price. The residual value guarantee under the Almaden Tower obligation is $89.4 million . The Almaden Tower lease is subject to standard covenants including certain financial ratios that are reported to the lessor quarterly. As of May 29, 2015 , we were in compliance with all of the covenants.

If we choose to remarket or are required to do so upon relinquishing the building, we are bound to arrange the sale of the building to an unrelated party and will be required to pay the lessor any shortfall between the net remarketing proceeds and the lease balance, up to the residual value guarantee amount less our investment in lease receivable.
