Non-GAAP Financial Measures

This presentation contains certain non-GAAP financial measures such as Adjusted Earnings per Share, Adjusted Operating Earnings (Loss), and Organic Growth (Decline). Adjusted Earnings per Share represents reported diluted earnings per share excluding the impact from adjustments related to the adoption of the U.S. Tax Cuts and Jobs Act, amortization of an inventory step up on the HAY equity method investment, a gain on the consolidation of the naughtone equity method investment, restructuring expenses and other special charges or gains, including related taxes. Adjusted Operating Earnings (Loss) represents reported operating earnings plus restructuring expenses and other special charges. Restructuring expenses include actions involving facilities consolidation and optimization, targeted workforce reductions, and costs associated with an early retirement program. Special charges include costs related to CEO transition, third party consulting costs related to the Company's profit enhancement initiatives, and acquisition related costs. Organic Growth represents the change in sales and orders, excluding currency translation effects and the impact of acquisitions. The Company believes these non-GAAP measures are useful for investors as they provide financial information on a more comparative basis for the periods presented.

Adjusted Earnings per Share, Adjusted Operating Earnings (Loss), and Organic Growth (Decline) are not measurements of our financial performance under GAAP and should not be considered an alternative to the related GAAP measurement. These non-GAAP measures have limitations as analytical tools and should not be considered in isolation or as a substitute for analysis of our results as reported under GAAP. Our presentation of non-GAAP measures should not be construed as an indication that our future results will be unaffected by unusual or infrequent items. We compensate for these limitations by providing equal prominence of our GAAP results.

Certain tables below summarize select financial information, for the periods indicated, related to each of the Company’s reportable segments. The North America Contract segment includes the operations associated with the design, manufacture, and sale of furniture products for work-related settings, including office, education, and healthcare environments, throughout the United States and Canada. The business associated with the Company's owned contract furniture dealer is also included in the North America Contract segment. North America Contract also includes the operations associated with the design, manufacture, and sale of high-craft furniture products and textiles including Geiger wood products, Maharam textiles, Nemschoff healthcare and Herman Miller Collection products. The International Contract segment includes the operations associated with the design, manufacture, and sale of furniture products, primarily for work-related settings, in the EMEA, Latin America and Asia-Pacific geographic regions. The Retail segment includes operations associated with the sale of modern design furnishings and accessories to third party retail distributors, as well as direct to consumer sales through eCommerce and Design Within Reach and HAY retail studios. Corporate costs represent unallocated expenses related to general corporate functions, including, but not limited to, certain legal, executive, corporate finance, information technology, administrative and acquisition-related costs.
