The type of transaction wasn't described in the filing with the Securities and Exchange Commission. But Peltz, whose hedge fund owns nearly a quarter of the company, said he expects "to contact and discuss a possible transaction involving the company with potential debt and/or equity financing sources, other shareholders of the company and other interested third parties." Shares jumped 11% to $4.84 in premarket trading. ArcSight Inc.'s (ARST) fiscal fourth-quarter earnings soared on strong sales that beat its optimistic outlook as the compliance and security software company continued to benefit from increased awareness of cybersecurity. Its shares climbed 12% to $22.22 in premarket trading as it also gave an upbeat outlook for the current fiscal quarter and year. Dell set aside $100 million as part of a potential legal settlement with U.S. regulators, a move that prompted the computer maker to lower its fiscal first-quarter earnings by five cents a share.

The New York-based drug makers studied apixaban in people with atrial fibrillation, a disease involving irregular heartbeat that increases the risk for stroke. Meanwhile, Bristol-Myers was upgraded by analysts at both Citigroup and Leerink Swann, which both highlighted the company's positive cancer-news this week, and potential for more catalysts on the way.

Under the agreement, Buckeye GP holders will receive 0.705 of a Buckeye Partner unit, valuing Buckeye GP at $41.01 a unit, a 32% premium to Thursday's closing price. About 20 million units will be issued as part of the deal, which it expects will dilute distributable cash flow per unit by 6% to 7% next year.
