APPENDIX B

In addition to addressing financial results calculated in accordance with GAAP, our Form 10-K/A contains presentations derived from “non-GAAP” adjusted measures, as defined below. The adjustments reflect items identified specific to fiscal year 2016 and our corresponding annual bonus plan for the named executive officers for such period.

The income from continuing operations for 2016 and 2015 is presented on a GAAP basis and also adjusted by multiplying pretax income by a normalized tax rate. The Company presents the below-described Adjusted EBITDA measures, 2016 results using a normalized tax rate and 2015 adjusted results because it considers them important supplemental measures of its performance and believes they are frequently used by securities analysts, investors and other interested parties in the evaluation of companies in its industry.

We present Adjusted Operating Income, which we define as operating income adjusted to exclude expenses incurred in connection with the Company’s streamlining initiatives, brand-exiting activities, acquisition related costs and loss on settlement of note receivable. The adjusted results for 2015 also exclude a $26.0 million charge related to the termination of certain contracts with our former joint venture partner in Kate Spade China Co., Ltd. Adjusted Operating Income as utilized in the Company’s 2016 Annual Incentive Plan is further adjusted to exclude share-based compensation. Adjusted Operating Income as utilized in the Company’s 2015 Annual Incentive Plan is further adjusted to exclude share-based compensation expense and the results of KATE SPADE SATURDAY, JACK SPADE brick and mortar, Kate Spade Brazil and Adelington Design Group exiting brands.

We present Adjusted EBITDA, which we define as income from continuing operations, adjusted to exclude income tax provision (benefit), interest expense, net, depreciation and amortization, net, losses on settlement of note receivable, expenses incurred in connection with the Company’s streamlining initiatives, brand-exiting activities, acquisition related costs, non-cash impairment charges, losses on asset disposals, non-cash share-based compensation expense and unrealized and certain realized foreign currency transaction adjustments, net. As presented herein, all references to Adjusted EBITDA are net of foreign currency transaction adjustments.

The Company believes that the adjusted results represent a more meaningful presentation of its historical operations and financial performance since these results provide period to period comparisons that are consistent and more easily understood. We present the above-described adjusted measures because we consider them important supplemental measures of our performance and believe they are frequently used by securities analysts, investors and other interested parties in the evaluation of companies in our industry. We also present Adjusted EBITDA Excluding Wind-Down Operations, which the Company defines as Adjusted EBITDA further adjusted to remove the Adjusted EBITDA of Kate Spade Saturday, Jack Spade brick and mortar, Kate Spade Brazil and brand exits in the Adelington Design Group segment. The Company believes this Adjusted EBITDA measure provides a presentation of its 2015 results that will provide investors with a means to compare those results to its 2016 results.

Adjustments to net sales for wind-down operations include net sales for Kate Spade Saturday, Jack Spade brick and mortar locations, Kate Spade Brazil and brand exits in the Adelington Design Group segment in 2015 and 2014. In addition to those items, the impacts of the 53rd week, changes in foreign currency exchange rates and strategic initiatives, including quality of sale and the conversion of the Hong Kong, Macau and Taiwan territories to a joint venture are adjusted in 2014. Refer to the tables entitled “Reconciliation of Non-GAAP Net Sales Information” for a reconciliation from GAAP results.

We provide a reconciliation of the non-GAAP financial measures to their most directly comparable GAAP financial measures below.
