NEW YORK (AP) _ Bestfoods, the maker of Skippy peanut butter and Hellmanns mayonnaise, agreed today to be purchased by European consumer goods conglomerate Unilever in an all-cash deal worth $20.4 billion, or $73 a share.

The final offer, made nearly a month after Unilever first courted Bestfoods, was 11 percent higher than Unilever's original unsolicited bid of $18.4 billion, or $66 a share.
