Ahold has formally given acting president and CEO John Rishton the top job at the company, the Dutch retail giant said today (16 November).

Rishton, who has held the dual roles on a temporary basis since Anders Moberg decided to leave the company earlier this year, will take the job with immediate effect.

"After careful consideration, the supervisory board unanimously reached the conclusion that John is the right individual to lead Ahold into the future," said René Dahan, chairman of Ahold's supervisory board.

Ahold also promoted deputy chief financial officer Kimberly Ross to the role of CFO. Dahan said: "Kimberly brings a proven track record in finance, as well as a deep knowledge of Ahold."

In April, Moberg announced he was to leave Ahold. Moberg has since joined Dubai-based retail group Majid Al Futtaim as chief executive.

Ahold has had a mixed financial performance this year. Last month, Ahold recorded a mixed performance in the US with like-for-like sales at its Stop & Shop outlets rising, while sales from its Giant-Landover business fell 1.8%.

Ahold warned that its "value improvement programme" at these outlets would continue to hit margins.

On a group basis, Ahold booked net sales of EUR6.3bn (US$9.1bn) for the three months to 7 October, a rise of 1.1% on a year earlier.

The weak dollar weighed on the numbers, however. At constant exchange rates, net sales were up 5.6%.
