|(1) | Non-GAAP net income and non-GAAP diluted EPS (along with non-GAAP weighted average diluted shares) are non-GAAP financial measures which represent net income excluding any non-cash interest related to ASC Topic 470,
non-cash non-recurring gains and charges, foreign currency translation gains and losses, and charges related to professional fees incurred as a result of the continuing correspondence with the Staff and the Special Committees review, all
net of tax, and any incremental dilutive shares related to our convertible notes that are covered by their respective hedges. The Company believes these are useful financial measures in evaluating its financial condition.

|(2) | Based on the average closing stock price for the years ended December 31, 2015 and 2014 there were potential dilutive shares related to our convertible notes for GAAP purposes; however, the Company will
not be responsible for issuing a portion of these shares as they are covered by our convertible notes hedges.

Adjusted EBITDA provides additional information for determining its ability to meet future debt service requirements, investing and capital expenditures, and is useful because it provides supplemental information to assist investors in evaluating
the Companys financial condition.

|(4) | Free Cash Flow, a non-GAAP financial measure, represents net cash provided by operating activities, plus cash received from the sale of trademarks and formation of joint ventures, less distributions to non-controlling
interests and capital expenditures. Free Cash Flow excludes notes receivable from sale of trademarks and the formation of joint ventures, cash used to acquire the membership interests of our joint venture partners, mandatory debt service
requirements, and other non-discretionary expenditures. Free Cash Flow should not be considered in isolation, as a measure of residual cash flow available for discretionary purposes, or as an alternative to operating results presented in accordance
with GAAP. The Company believes Free Cash Flow is useful because it provides information regarding actual cash received in a specific period from the Companys comprehensive business strategy of maximizing the value of its brands through
traditional licensing, international joint ventures and other arrangements. We have excluded the cash used to buy back our joint venture membership interests from the above definition because we believe that, like other acquisitions, such actions
are capital transactions. It also provides supplemental information to assist investors in evaluating the Companys financial condition and ability to pursue opportunities that enhance shareholder value.
