[1] Includes amortization of debt issue costs.

[2] Includes interest income, foreign currency exchange (gain) loss and equity in income of affiliates and excludes distributions from NCM.

[3] Includes cash distributions received from equity investees that were recorded as a reduction of the respective investment balances. In an effort to more closely align our reported Adjusted EBITDA with our operating cash flow, which provides our chief operating decision maker with more comprehensive cash flow information, and for consistency with our peers, beginning with the three months ended March 31, 2016, Adjusted EBITDA now includes total cash distributions received from equity investees, including the cash distributions recorded as a reduction of the respective investment balance. Adjusted EBITDA for the three and nine months ended September 30, 2015 has been adjusted to reflect comparable presentations.

[4] Distributions from NCM and other cash distributions from equity investees are reported entirely within the U.S. operating segment.
