Skype, the internet phone service, has filed for an IPO and plans to be listed on the NASDAQ. The numbers are mind boggling whichever way you look at it.

$406.2 million: Revenues for the six-month period ended June 30, up 25% from $324.8 million in the year-earlier period.

560 million: Registered users on June 30, up 47% from 390 million a year ago.

95 billion: Minutes of voice and video racked up by users so far this year.

839: Employees and contractors at June 30, up from 640 a year ago.

$343.8 million: Net charges from a legal settlement with Joltid, the firm controlled by Skype’s co-founders who sued the company last year alleging copyright theft. Skype disclosed in November that Joltid would take a 14% stake in the settlement, but didn’t detail the other terms. In the IPO filing, Skype said Joltid received a 10% stake valued at the time at $224 million, a cash payment of $85 million and a warrant to purchase equivalent to a 1% stake. Joltid also invested $80 million in Skype for another 3.4% stake.
