Shares of JLG Industries(JLG Quote) were among the NYSE's winners Monday, jumping 33% after the construction-equipment maker agreed to be acquired by Oshkosh Truck(OSK Quote) for $3 billion in cash.

Oshkosh will pay $28 a share for JLG, representing a 35% premium over Friday's closing price of $20.75. "The acquisition of JLG is the latest broad-based initiative in the continuing transformation of Oshkosh Truck Corporation," Oshkosh said.

Mattel(MAT Quote) rose 5% after the toymaker posted better-than-expected third-quarter results. The company earned $239 million, or 62 cents a share, on revenue of $1.79 billion. Analysts polled by Thomson First Call expected earnings of 61 cents a share on revenue of $1.63 billion. During the year-earlier period, Mattel earned $225.3 million, or 55 cents a share, on revenue of $1.67 billion.

Separately, Mattel said that a review of historical stock option grants, going back to 1993, found no backdating of stock option grants, no material inaccuracies in financial statements, and no misconduct or manipulation associated with the stock option grant dates.

The review did turn up some unintentional errors associated with incorrect accounting measurement dates for certain grants made before 2003. The errors resulted in an after-tax charge to earnings of 3 cents a share during the third quarter. Mattel shares recently were up $1.06 to $21.76.
