[1] The basis of the financial statements of the CB Portfolio used in the calculation of the Company’s equity in earnings for the year ended December 31, 2014 was computed using the 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. The calculation includes the effects of purchase price adjustments determined at the date the Company acquired its interests in the CB Portfolio. The Company consummated the acquisition of a 48.0% interest in 36 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 its ownership, the Company completed its acquisition of the 48.0% interest in stages, which resulted in a variation in its ownership percentage from 25.3% to 48.0% in all 36 of the CB Portfolio operating 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 its 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 it held during the applicable period, which was a 67.0% effective interest in the 28 properties during the first and second quarters of 2014 and through August 18, 2014. Due to the Company's decision not to exercise the first purchase option to acquire additional interests in the CB Portfolio, on August 19, 2014, the Company's ownership interest in all 35 unconsolidated operating properties in the CB Portfolio reverted to 48.0% and remained at 48.0% through December 31, 2014.

[2] For the year ended December 31, 2014, the losses incurred from January 1, 2014 through August 18, 2014 while the Company held 67% ownership in 28 of the properties exceeded the income earned from August 19, 2014 through December 31, 2014 while the Company held 48% ownership in 36 properties.

[3] The Company was entitled to a preferred payment for the first year of its investment and the proportionate share of the remaining operating cash flows in the CB Portfolio and it was currently entitled to its proportionate share of the operating cash flows in the CB Portfolio. During the period from March 18, 2013 to March 17, 2014, the Company was entitled to $13.0 million related to its preferred payment, all of which has been paid, and the Company received approximately $1.0 million in other distributions, as of December 31, 2014.

[4] The Company recorded in the calculation of equity in losses in the CB Portfolio the amortization of the net difference in the Company’s carrying value of investment as compared to the underlying equity in net assets of the investee.
