Forward-Looking StatementsThis press release contains forward-looking statements regarding future events and financial performance. These statements are based on current expectations and assumptions involving judgments about, among other things, future economic, competitive and market conditions and future business decisions, all of which are difficult or impossible to predict accurately and many of which are beyond PDI's control. These statements also involve known and unknown risks, uncertainties and other factors that may cause PDI's actual results to be materially different from those expressed or implied by any forward-looking statement. For example, with respect to statements regarding projections of future revenues, growth and profitability, actual results may differ materially from those set forth in this release based on the loss, early termination or significant reduction of any of our existing service contracts, the failure to meet performance goals in PDI's incentive-based arrangements with customers or the inability to secure additional business. Additionally, all forward-looking statements are subject to the risk factors detailed from time to time in PDI's periodic filings with the Securities and Exchange Commission, including without limitation, PDI's Annual Report on Form 10-K for the year ended December 31, 2011, and PDI's subsequently filed quarterly reports on Form 10-Q and current reports on Form 8-K.
