Market Insider | What's Shaking | Earnings to Watch | Before the Bell

Check out which companies are making headlines before the bell on Tuesday:

AIG — The insurance banking giant is replacing Baker Hughes In the S&P 100 Index, with S&P citing the drop in the oilfield service company's market cap below the $21 billion mark. Separately, AIG has been designated as "systemically important" and subject to increased regulatory oversight, along with Prudential Financial (PRU) and General Electric's GE Capital unit.

Dell — CEO Michael Dell saw his pay cut by 14 percent to $13.9 million last year, as personal computer sales slumped. The majority of Dell's compensation consisted of stock awards, with his salary remaining unchanged at $950,000.

Dollar General— The discount retailer matched estimates with first quarter profit of 71 cents per share, excluding certain items, but it's cut its full year profit forecast below Street consensus due to slowing sales growth.

FedEx — FedEx raised its quarterly dividend by a penny to 15 cents per share, and also announced an acceleration of its aircraft fleet modernization, choosing to retire a number of its jets earlier than previously planned.

General Motors — The automaker will be added to the S&P 500 after the closing of trading Thursday, replacing H.J. Heinz (HNZ). Heinz is being bought by Berkshire Hathaway and 3G Capital.

Buffalo Wild Wings — The restaurant chain's stock has been removed from the "Focus Idea" list at Baird Equity, which cites valuation. Baird is maintaining an "outperform" rating on the stock.

AstraZeneca —The drug maker has dropped development of its rheumatoid arthritis pill known as fostamatinib, after disappointing results in a late stage trial. AstraZeneca will take a $140 million charge, but the bigger impact may be on Rigel Pharmaceuticals , the U.S. firm that struck a licensing deal for the drug with AstraZeneca three years ago.

Carlyle Group — Calpers, the nation's largest public pension fund, is selling its four percent stake in Carlyle. Calpers had acquired a 5.5 percent stake back in 2001 for $175 million, well before Carlyle's 2012 initial public offering, and the stake is now worth $373 million.

Lululemon —Lululemon's Astro and Groove yoga pants are starting to reappear in stores, three months after they had been recalled because the fabric was considered too sheer.

Walt Disney — Disney has raised theme park prices, with a one-day adult ticket at Disneyland now at $92, a five dollar increase. Tickets for children are also higher by five dollars at $87.

Ulta Salon — Goldman Sachs has cut its rating on Ulta to "neutral" from "buy", saying the company must invest more to take advantage of e-commerce opportunities.

CME Group —Wells Fargo has upgraded CME to "outperform" from "market perform", in part because of increased business resulting from Dodd-Frank regulations.

ExactTarget — The cloud marketing platform operator will be acquired by Salesforce.com for $33.75 per share in cash, or about $2.5 billion. The price is a 52.7 percent premium over ExactTarget's Monday closing price.
