Overstock.com founder back as CEO

New York -- Overstock.com founder Patrick M. Byrne has returned as CEO of online discount retailer.

Byrne took a medical leave of absence in February to address cardiac issues thought to be associated with cancer treatments received much earlier in his life.

During his leave, Byrne retained his position as chairman, but appointed Jonathan Johnson, formerly president, as acting CEO. Recently, Johnson was nominated to stand for election to the board of directors at the company's annual stockholders' meeting in May. The company's proxy materials note that if Johnson is elected, the board intends to appoint him as executive vice chairman of the board.
