Campbell Soup Co , the world's largest soup maker, reported a higher-than-expected quarterly profit, helped by a fall in advertising and promotion expenses.

For the first quarter ended October 30, net earnings attributable to Campbell Soup were $265 million, or 82 cents a share, compared with $279 million, or 82 cents a share, a year ago.

Sales fell 1 percent to $2.16 billion.

Analysts on average were expecting a profit of 79 cents a share, on sales of $2.21 billion, according to Thomson Reuters I/B/E/S.
