Carlyle co-founder David M. Rubenstein may need to amend his firm’s investment criteria. Rubenstein recently admitted to missing out on a whopper of a deal: getting in on the ground floor of Facebook.

Turns out that a few years ago the future husband of Rubenstein’s daughter pitched the Carlyle chieftain on behalf of Mark Zuckerberg, Facebook’s founder.

Zuckerberg was dropping out of Harvard to focus on Facebook and needed capital.

Rubenstein asked what the company did.

He was told it helped college students meet each other.

“I don’t think I’m that kind of investor,” Rubenstein recalled saying. “I don’t think I want to meet him.”

Recent valuations estimate privately held Facebook to be worth around $50 billion.

Now, Rubenstein regrets the response.

Though he missed out on the Facebook windfall, Rubenstein is doing just fine. When Carlyle goes public, his share of stock will make him a billionaire — at least on paper.

Ticket masters

The NHL Washington Capitals, which lost in the second round of the playoffs in four straight to the Tampa Bay Lightning, are doing better off the ice than on. Season ticket renewals are clicking at a 98 percent rate, according to the team.

The NBA Wizards, who recorded the fourth worst record in the league at 23-59 , are renewing at an 80 percent renewal rate and expanding their base.

“We have sold more than 1,200 new season tickets thus far after the season,” said spokesman Kurt Kehl, way ahead of last year’s pace.

To help overcome the team’s poor performance and the threat of 2011-12 season cancellation because of labor problems, the Wizards plan to hold a June 23 NBA draft party at the Verizon Center for season ticket holders, prospects and fans.
