Non-GAAP Supplementary Materials

Non-GAAP Supplementary Materials In an effort to provide investors with additional information regarding the company's results as determined by generally accepted accounting principles (GAAP), the company also discusses in these materials the following Non-GAAP information which management believes provides useful information to investors. Operating (Non-GAAP) Earnings, EPS, Pre-Tax Income, and Segment Profit Management presents certain financial measures excluding the effects of certain acquisition-related charges, non-operating retirement-related costs, and any related tax impacts. Management uses the term "operating" to describe this view of the company's financial results and other financial information. For acquisitions, these measures exclude the amortization of purchased intangible assets and acquisition-related charges such as in-process research and development, transaction costs, applicable restructuring and related expenses, and tax charges related to acquisition integration. For retirement-related costs, the company has characterized certain items as operating and others as non-operating. The company includes service cost, amortization of prior service cost and the cost of defined contribution plans in its operating results. Non-operating retirement-related costs include interest cost, expected return on plan assets, amortized actuarial gains/losses, the impacts of any plan curtailments/settlements, multi-employer plan costs, pension insolvency costs, and other costs. Non-operating costs primarily relate to changes in pension plan assets and liabilities which are tied to market performance, and management considers these costs to be outside the operational performance of the business. Management’s calculation of these operating measures, as presented, may differ from similarly titled measures reported by other companies. Overall, management believes that providing investors with an operating view as described above provides increased transparency and clarity into both the operational results of the business and the performance of the company’s pension plans, improves visibility to management decisions and their impacts on operational performance, enables better comparison to peer companies, and allows the company to provide a long term strategic view of the business going forward. For the 2015 earnings per share road map, the company is utilizing an operating view to establish its objectives and track its progress.

Non-GAAP Supplementary Materials Constant Currency Management refers to growth rates at constant currency or adjusting for currency so that certain financial results can be viewed without the impact of fluctuations in foreign currency exchange rates, thereby facilitating period-to-period comparisons of the company's business performance. Financial results adjusted for currency are calculated by translating current period activity in local currency using the comparable prior year period’s currency conversion rate. This approach is used for countries where the functional currency is the local currency. Generally, when the dollar either strengthens or weakens against other currencies, the growth at constant currency rates or adjusting for currency will be higher or lower than growth reported at actual exchange rates. Cash Flow Management uses a free cash flow measure to evaluate the company’s operating results, plan share repurchase levels, evaluate strategic investments and assess the company’s ability and need to incur and service debt. The entire free cash flow amount is not necessarily available for discretionary expenditures. The company defines free cash flow as net cash from operating activities less the change in Global Financing receivables and net capital expenditures, including the investment in software. A key objective of the Global Financing business is to generate strong returns on equity, and increasing receivables is the basis for growth. Accordingly, management considers Global Financing receivables as a profit-generating investment, not as working capital that should be minimized for efficiency. Therefore, management includes presentations of both free cash flow and cash flow from operations that exclude the effect of Global Financing receivables. Divestitures Management presents certain financial results excluding the effects of the divestitures of the printer business and the personal computer (PCD or PC) business. In June 2007, the company divested 51 percent of its printer business and divested the remaining 49 percent quarterly over the following 3 years. In April 2005, the company completed the sale of its PCD business. Management believes that presenting certain revenue measures without these items is more representative of the company’s operational performance and provides additional insight into, and clarifies the basis for, historical and/or future performance, which may be more useful for investors.
