FORECASTED AND ACTUAL NON-GAAP NET INCOME PER SHARE

(Unaudited)

Non-GAAP diluted net income per share is a “non-GAAP financial measure” that excludes items resulting in other income in fiscal 2015 which consists of (a) the sale of the right to operate Calvin Klein Performance stores in Asia, including the sale of the Company’s interest in a joint venture that operated Calvin Klein Performance stores in China and expenses associated with this other income incurred in the fourth quarter of fiscal 2015, (b) the reduction of a portion of the estimated contingent consideration payable in connection with the acquisition of Vilebrequin, and (c) the early extinguishment of debt due to the seller of Vilebrequin for an amount less than the principal amount of this debt. Management believes that this non-GAAP financial measure provides meaningful supplemental information regarding our performance by excluding items of other income that are not indicative of our core business operating results. Management uses this non-GAAP financial measure to assess our performance on a comparative basis and believes that it is also useful to investors to enable them to assess our performance on a comparative basis across historical periods and facilitate comparisons of our operating results to those of our competitors.

RECONCILIATION OF FORECASTED AND ACTUAL NET INCOME TO FORECASTED AND ACTUAL ADJUSTED EBITDA

(In thousands)

(Unaudited)

Adjusted EBITDA is a “non-GAAP financial measure” which represents earnings before depreciation and amortization, interest and financing charges, net, and income tax expense and excludes items resulting in other income net of related expenses, in the fiscal 2015 period which consists of (a) the sale of the right to operate Calvin Klein Performance stores in Asia, including the sale of the Company’s interest in a joint venture that operated Calvin Klein Performance stores in China and expenses associated with this other income incurred in the fourth quarter of fiscal 2015, (b) the reduction of a portion of the estimated contingent consideration payable in connection with the acquisition of Vilebrequin, and (c) the early extinguishment of debt due to the seller of Vilebrequin for an amount less than the principal amount of this debt. Adjusted EBITDA is being presented as a supplemental disclosure because management believes that it is a common measure of operating performance in the apparel industry. Adjusted EBITDA should not be construed as an alternative to net income as an indicator of the Company’s operating performance, or as an alternative to cash flows from operating activities as a measure of the Company’s liquidity, as determined in accordance with generally accepted accounting principles.
