The seemingly never-ending saga involving Action Alerts Plus holding Broadcom Ltd.'s (AVGO) - Get Report hostile bid and proxy war to take control of Qualcomm Inc. (QCOM) - Get Report came to a definitive close on Wednesday. The unsolicited bidder, Broadcom, announced that it had terminated its $79 a share offer for Qualcomm. The chip-maker also withdrew a change-of-control slate of director nominees it had up for election to Qualcomm's board.
