On January 28, 2016, we announced that our multifamily business is non-core. As a result, we plan to opportunistically exit our multifamily portfolio and no longer allocate capital to new communities in this business.

On February 4, 2016, we entered into a Purchase and Sale Agreement to sell the Radisson Hotel & Suites in Austin for $130,000,000. This transaction is subject to normal closing conditions and is expected to close in second quarter 2016.

On March 1, 2016, we sold our remaining Kansas and Nebraska oil and gas properties for $21,000,000, with a $2,000,000 contingency payment if the WTI oil price exceeds $60 Bbl for 60 consecutive trading days within one year following closing. We will incur an additional loss related to the sale of Kansas and Nebraska oil and gas properties due to allocation of goodwill on a relative fair value basis to the disposal group that constitutes a business.
