NEW YORK ( TheStreet) -- There is one more interested party in the NYSE Euronext ( NYX) takeover battle -- the ex-wife of NYSE's chief operating officer.

According to a Securities and Exchange Commission filing on Monday, the ex-wife of NYSE COO Operating Officer Larry Leibowitz received thousands of shares of the exchange as part of a divorce settlement.

"The reporting person transferred 10,213 shares of common stock to the reporting person's former spouse pursuant to property settlement in a divorce proceeding. The reporting person disclaims beneficial ownership of the securities owned by the former spouse," a footnote to the filing said.

The transaction took place on April 8, and Leibowitz retains 36,659 shares of the NYSE following the transaction.

Leibowitz joined the NYSE in 2007 from UBS ( UBS) and become COO in 2010, according to the NYSE Web site. He is also the older brother of Daily Show anchor Jon Stewart.

A spokesperson for the NYSE confirmed the filing but offered no further comment.

On Sunday, NYSE Euronext rejected the $11.3 billion hostile takeover bid from Nasdaq OMX ( NDAQ) and IntercontinentalExchange ( ICE). the exchange reaffirmed its previously announced merger agreement with Germany's Deutsche Boerse AG.

Shares of NYSE Euronext were down 2.2%, to $37.83, in morning trading.
