Nasdaq OMX Group Inc. (NDAQ) and buyout shop Carlyle Group LP (CG) discussed a deal to take the exchange company private, though the talks didn't result in a transaction and they aren't ongoing, according to people familiar with the matter.

Carlyle reached out to Nasdaq, one of the people said. The buyout firm's chief financial officer, Adena Friedman, brokered a meeting with Nasdaq OMX, where she previously was chief financial officer.

Carlyle's dealmakers conducted preliminary due diligence, but a gulf emerged between what the buyout shop was inclined to pay and what Nasdaq felt it was worth, the person said.

A move to private ownership would have been a dramatic shift for the $5 billion exchange group, which serves as a gateway for companies to raise investment funds via public share-listings. Carlyle itself listed on Nasdaq when it went public last year. Nasdaq's so-called enterprise value, a figure that includes its debt, is more than $6 billion, a doable size for a buyout, given current market conditions.

The Nasdaq Stock Market became a shareholder-owned company following its spinoff from the National Association of Securities Dealers in 2000. The Nasdaq gained status as a regulated stock exchange in 2006.

News of the going-private talks was first reported by Fox Business News.

Ms. Friedman, who worked at Nasdaq OMX in various positions for 18 years before leaving in early 2011, has since remained on cordial terms with Robert Greifeld, Nasdaq OMX's chief executive, according to people close to the executives. She was a key figure in deals that expanded the exchange company's overseas profile, helping to navigate its 2008 purchase of Nordic exchange group OMX AB. She also helped put together Nasdaq OMX's acquisition of the Philadelphia Stock Exchange, which helped to bolster Nasdaq OMX's position in stock-options trading.
