Consumer goods giant Sara Lee Corp on Thursday posted a slight rise in third quarter net income as it was boosted by favourable foreign exchange rates and strong sales of its key intimate apparel and underwear brands. The Chicago-based company, which makes everything from food to household products, posted net income of $269 million, or 33 cents a share, versus $257m, or 31 cents, in the year-ago period. Revenue rose 3.6 per cent to $4.35 billion from the year prior.
