PARTNERS' CAPITAL OF AMERICAN ASSETS TRUST, L.P.

PARTNERS' CAPITAL OF AMERICAN ASSETS TRUST, L.P.

Noncontrolling interests in our Operating Partnership are interests in the Operating Partnership that are not owned by us. Noncontrolling interests consisted of 17,899,516 common units (the “noncontrolling common units”), and represented approximately 28.6% of the ownership interests in our Operating Partnership at June 30, 2015. Common units and shares of our common stock have essentially the same economic characteristics in that common units and shares of our common stock share equally in the total net income or loss distributions of our Operating Partnership. Investors who own common units have the right to cause our Operating Partnership to redeem any or all of their common units for cash equal to the then-current market value of one share of our common stock, or, at our election, shares of our common stock on a one-for-one basis.

During the six months ended June 30, 2015, approximately 5,741 common units were converted into shares of our common stock.

Earnings Per Unit of the Operating Partnership

Basic earnings (loss) per unit (“EPU”) of the Operating Partnership is computed by dividing income (loss) applicable to unitholders by the weighted average Operating Partnership units outstanding, as adjusted for the effect of participating securities. Operating Partnership units granted in equity-based payment transactions are considered participating securities prior to vesting. The impact of unvested Operating Partnership unit awards on EPU has been calculated using the two-class method whereby earnings are allocated to the unvested Operating Partnership unit awards based on distributions and the unvested Operating Partnership units’ participation rights in undistributed earnings (losses).

The calculation of diluted earnings per unit for the three month periods ended June 30, 2015 and 2014 does not include the weighted average of 176,767 and 431,059 unvested Operating Partnership units, respectively, as these equity securities are either considered contingently issuable or the effect of including these equity securities was anti-dilutive to income from continuing operations and net income attributable to the unitholders. The calculation of diluted earnings per unit for the six month periods ended June 30, 2015 and 2014 does not include the weighted average of 211,526 and 419,024 unvested Operating Partnership units, respectively.
