''Nestlé has delivered a good performance by any measure in the first half of 2002, demonstrating its capacity for growth and performance improvement even in a difficult global environment,'' Peter Brabeck, the chief executive, said. Nestlé took charges totaling $1.1 billion to write down the value of some units, notably Spillers pet food, which it acquired in 1998. Spillers has suffered as European consumers have switched to dry pet food. Nestlé's registered shares rose 3 percent in Swiss trading to close at 335 Swiss francs ($223.62) a share. Mr. Brabeck told analysts that Nestlé would introduce another cost-cutting program over the next three years, reducing the number of production plants, selling units and upgrading production. An earlier plan completed last year reduced costs by $2.7 billion.
