Impairments	(17) Impairments During the year ended December 31, 2012, the Company executed an expansion of its tenant relationship with General Atomics in Poway, CA, to a total of 396,000 square feet, consisting of the following: (i) a lease extension of 281,000 square feet through June 2024, (ii) a new 10—year lease for a 115,000 square feet building to be developed and (iii) the purchase of a 19 acre land parcel from the Company for $19 million. As a result of the land sale the Company recognized an impairment charge of $7.9 million, which reduced the carrying value of the Company's investment from $27 million to the $19 million sales price. The fair value of the Company's land parcel was based on the sales price from its disposition in conjunction with this transaction. The sales price of the land parcel was considered to be a Level 3 measurement within the fair value hierarchy. During the year ended December 31, 2011, the Company concluded that its senior secured term loan to Delphis was impaired and established a provision for losses (impairment) of $15.4 million. The impairment resulted from the Company's conclusion that the carrying value of its loan was in excess of the fair value of the loan's underlying collateral assets. This provision for losses reduced the carrying value of its investment from $91.1 million to its fair value of $75.7 million. The fair value of the Company's loan investment was based on a discounted cash flow valuation model and inputs considered to be a Level 3 measurement within the fair value hierarchy. Inputs to this valuation model include real estate capitalization rates, discount rates, earnings multiples, industry growth rates and operating margins, some of which influence the Company's expectation of future cash flows from the loan and, accordingly, the fair value of its investment. On October 12, 2010, the Company concluded that its 35% interest in HCP Ventures II, which owns 25 senior housing properties leased by Horizon Bay Communities or certain of its affiliates (collectively "Horizon Bay"), was impaired. The impairment resulted from the recent and projected deterioration of the operating performance of the properties leased by Horizon Bay from HCP Ventures II. During the year ended December 31, 2010 the Company recognized an impairment of $71.7 million related to its investment in HCP Ventures II, which reduced the carrying value of its investment from $136.8 million to its fair value of $65.1 million. The fair value of the Company's investment in HCP Ventures II was based on a discounted cash flow valuation model that is considered to be a Level 3 measurement within the fair value hierarchy. Inputs to this valuation model include real estate capitalization rates, discount rates, industry growth rates and operating margins, some of which influence the Company's expectation of future cash flows from HCP Ventures II and, accordingly, the fair value of its investment.
