Among the companies whose shares are expected to actively trading in Tuesday's session are Oshkosh Corp. (OSK), BP PLC (BP) and Taseko Mines Ltd. (TGB). Oshkosh won contracts worth $690.5 million to supply the Army with tactical trucks and trailers, the Defense Department said Friday.

It also includes the sale of 98 palletized loading system trailers. Shares rose 2.1% at $30.63 after hours. BP killed speculation Tuesday that it was looking for a white knight investor to take a large equity stake in the company by saying it won't issue new equity to raise money to cover the costs of the oil spill in the Gulf of Mexico. BP would welcome it if any existing shareholders or new investors want to expand their holding in the company by buying already-listed shares, but no new shares will be listed, said a company spokeswoman. American depositary shares rose 5.8% to $31.06 in premarket trading. The approval process for Taseko Mines' gold-copper mine in central British Columbia is likely to be "messy" after a Canadian review panel concluded there would be a significant adverse environmental impact.

Taseko shares slumped 11% to $3.50 in premarket trading. Cliffs Natural Resources Inc. (CLF) said Spider Resources Inc. (SDERF, SPID.RQ) broke off its agreement to merge with KWG Resources Inc.

Chromite is used to make chromium, which is in turn used in the production of stainless steel. Earlier this month, Cliffs raised its bid on Spider 27% to about C$109 million (US$102.6 million), which Spider determined trumped the terms it agreed to when it entered a binding letter of intent to merge with KWG.
