[1] The basis of the financial statements of the CB Portfolio used in the calculation of the Company’s equity in earnings for the first quarter of 2014 was computed using the Company’s cost basis for its investment in the CB Portfolio’s underlying assets and liabilities for its properties at the dates the Company acquired its interests in the CB Portfolio. For the first quarter of 2014 this included 28 properties. The calculation includes the effects of purchase price adjustments determined at the date the Company acquired its interests in the CB Portfolio. We consummated the acquisition of a 48.0% interest in 35 properties of the CB Portfolio. As a result of lender consents that were required to be obtained from various lenders to the CB Portfolio prior to our ownership, we completed our acquisition of the 48.0% interest in stages, which resulted in a variation in our ownership percentage from 25.3% to 48.0% in all 35 of the CB Portfolio properties from March 18, 2013 to September 30, 2013. Effective October 1, 2013, the Company and the CB Portfolio sellers amended the purchase and sale agreement, subject to receipt of all required third party consents, to increase the Company’s ownership interest by 19.0% in 28 of the 35 properties (thereby increasing its ownership in the 28 properties to 67%) in exchange for the Company’s 48.0% interest in seven of the properties (thereby reducing our ownership in the seven properties to 0%) and deferring the Company’s acquisition of any interests in two of the properties, plus a $20.2 million cash payment. Accordingly, the Company recognized its proportionate share of earnings of the CB Portfolio for the specific percentage of ownership interest we held during the applicable period, which was a 67.0% effective interest in the 28 properties during the first quarter of 2014.
