Item 8.01. Other Events
On August 22, 2012, Marc P. Lefar, Chief Executive Officer of Vonage Holdings Corp. (the "Company"), adopted a pre-arranged stock trading plan in accordance with Rule 10b5-1 of the Securities Exchange Act of 1934 and the Company's securities trading compliance policy.
The plan was initiated in connection with a long-term strategy for asset diversification and family financial planning. Mr. Lefar holds vested and unvested options and restricted stock units representing a total of approximately 12.6 million shares. The plan provides for the sale of up to three million shares acquired through the exercise of stock options, over a period between September 11, 2012 and August 7, 2013. Subject to minimum price thresholds, shares will be sold under the plan on the open market at prevailing market prices. Assuming that all of the contemplated options are exercised and the underlying shares sold under the plan, Mr. Lefar would remain well above the stock ownership thresholds established by the Company's Board of Directors. Transactions under the plan will be disclosed publicly through Form 4s filed with the Securities and Exchange Commission.
