[1] For our non-real estate investments in Steward, we compared our carrying value of all such investments to the fair value of the underlying collateral, which resulted in a $90 million impairment to our equity investment. The remaining charge relates to reserving for other outstanding receivables, including receivables for reimbursement of property taxes and insurance.

[2] For the real estate leased to Steward, we made a comparison of the projected undiscounted future cash flows with the net book value of each asset. For less than 10 of these properties, the carrying value was deemed not recoverable, and we recorded an impairment charge to reduce the carrying value to its estimated fair value. In estimating fair value for these properties, we, along with assistance from a third-party, independent valuation firm, used a combination of cost, market and income approaches using Level 3 inputs. The cost approach used comparable sales to value the land and cost manuals to value the improvements. The value derived from the market approach was based on sale prices of similar properties. For the income approach, we divided the expected operating income (i.e. rent revenue less expenses, if any) from the property by a market capitalization rate (range from 6.5% to 9.5%).
