Dutch retailer Ahold said on Thursday that fourth-quarter net profit more than doubled, thanks to its domestic activities, and said it would increase its share buyback to 3 billion euros ($4 billion).

Profit at the world's fourth-biggest food retailer and foodservice group by sales rose to 240 million euros ($320.9 million) from 108 million euros ($144.4 million) a year ago, beating an average forecast of 169 million euros ($225.9 million) in a Reuters poll of 14 analysts.
