Nasdaq

said Tuesday that it plans to acquire a majority of the

Easdaq's

shares, expanding the electronic stock market from its trading platform in the U.S. and Japan into Europe.

Nasdaq will buy 58% of Easdaq's diluted stock, giving Nasdaq roughly 51% ownership after it issues additional shares and exercises warrants outstanding.

Nasdaq plans to restructure Easdaq, which was established in 1996, into

Nasdaq Europe

, "a globally linked, pan-European market." Nasdaq will implement a new trading system for Nasdaq Europe in May or June.
