Strong Financial Performance and Robust Cash Position Support Distribution

KING OF PRUSSIA, Pa.--(BUSINESS WIRE)-- InterDigital, Inc. (NASDAQ:IDCC) is pleased to announce that its Board of Directors has approved the company’s initial dividend policy, pursuant to which the company will pay a regular quarterly cash dividend of $0.10 per share on its common stock. The Board has declared the first quarterly cash dividend to be payable on February 2, 2011 to shareholders of record of the company’s common stock at the close of business on January 12, 2011.

“With one of the strongest wireless technology portfolios in the industry, InterDigital® continues to drive shareholder value through a combination of strategic investments in its business and appropriate levels of capital return, both in the form of cash dividends and stock repurchases,” said Terry Clontz, InterDigital’s Chairman of the Board. “The initiation of a regular dividend reflects the stability of the company, its strong performance over the past several years and our confidence in the long-term prospects for the business.”

In establishing the initial level of the regular quarterly dividend, the Board of Directors considered a number of factors, including current and future performance metrics, use of cash to grow the business and maintain ample flexibility to pursue strategic investments. The Board will review the company’s capital policy periodically to determine the appropriate level of dividend distributions as well as other means to return capital to shareholders, including the repurchase of common stock.
