Take a look at some of Tuesday's morning movers:
Barclays - CEO Bob Diamond has resigned in the wake of the Libor manipulation scandal that saw the bank fined more than $450 million by U.S. and U.K. regulators. That comes a day after chairman Marcus Agius stepped down from his position, although the bank now says he'll lead the search for a new CEO.
Microsoft - The company will take a $6.2 billion noncash charge to write down goodwill in its online services division. Most of that writedown is related to its 2007 purchase of aQuantive, an online ad agency, for $6.3 billion. Such writedowns are required by accounting rules if the value of an investment or an acquisition has diminished.
Chesapeake Energy - Investor Carl Icahn told CNBC’s “Fast Money” that the company is a “very undervalued asset” and that he wouldn’t sell his shares now. Separately, Reuters is reporting that Chesapeake, along with Canada’s Encana, are the targets of a Justice Department probe involving possible bidding collusion between the two in Michigan land deals two years ago.
Forest Laboratories - The company has responded to a letter sent by Icahn to the company yesterday, which accused the board of putting Chairman and CEO Howard Solomon’s interests ahead of shareholders. The drugmaker says it is “not surprised by Mr. Icahn’s theatrical display of self-serving rhetoric.”
Apple - Apple won another interim victory in its ongoing legal battle with Samsung, with a judge rejecting a Samsung request to lift a ban on U.S. sales of its Galaxy Tab 10.1. A patent trial involving the two is set to begin July 30.
General Motors, Facebook - The two are in talks to return General Motors to Facebook as a paid advertiser, according to The Wall Street Journal. That comes a few months after a GM executive said Facebook ads had little impact and that GM would stop advertising on the social networking site.
Navistar - The Journal reports the truck maker will announce it’s backing away from pollution-reduction technology that has hurt its sales and caused conflict with federal regulators.
Boeing - Boeing has raised its 20-year forecast for jet sales, citing an increase in demand from emerging markets, as well as an accelerating push by airlines to make their fleets more fuel efficient.
