Forward Looking Statements and Risk Factors

This release contains forward-looking statements within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995 regarding future growth, cost reductions, profitability and capital return for shareholders. These forward-looking statements are subject to risks and uncertainties that may cause actual results to differ materially, including the impact of competition on our product sales and for our customers and partners and any resulting loss of business; the impact of increased competition due to consolidation in our industry or competition from companies that are larger or that

have greater resources than we do; potential fluctuations in results and future growth rates; risks associated with global economic conditions and external market factors; the market acceptance of our products and changing market demands, including demands for differing technologies or product and services offerings; our ability to successfully integrate our acquisitions into our business; possible delays in the development, availability and shipment of new products due to engineering, manufacturing or other delays; increasing costs and differing uses of capital; changes in key personnel that may cause disruption to the business; the impact of restructuring actions; and the impact of global conflicts that may adversely impact our business. Many of these risks and uncertainties are discussed in the Company’s Quarterly Report on Form 10-Q for the quarter ended September 30, 2013, and in other reports filed by Polycom with the SEC.

GAAP to non-GAAP Reconciliation

To supplement our consolidated financial statements presented on a GAAP basis, Polycom uses non-GAAP measures of operating results, net income and income per share, which are adjusted to exclude certain costs, expenses, gains, and losses we believe appropriate to enhance an overall understanding of our past financial performance and also our prospects for the future. These adjustments to our current period GAAP results are made with the intent of providing both management and investors a more complete understanding of Polycom’s underlying operational results and trends and our marketplace performance. For example, the non-GAAP results are an indication of our baseline performance before gains, losses, or other charges that are considered by management to be outside of our core operating results. In addition, these adjusted non-GAAP results are among the primary indicators management uses as a basis for our planning and forecasting of future periods. The presentation of this additional information is not meant to be considered in isolation or as a substitute for net income or diluted net income per share prepared in accordance with generally accepted accounting principles in the United States.
