Fashion retail giant Gap has unveiled a new global structure designed to reflect the company’s increasingly international footprint and to drive long-term growth.

Gap, which now has more than 3,200 stores in over 40 countries covering its five brands, said it would bring together its North American, International, Online, Outlet and Franchise divisions under a single global executive for each brand from the start of fiscal 2013.

“Our strong performance gives us the confidence to make this move to bring each brand together with the goal of gaining market share around the world and enhancing shareholder value,” said Glenn Murphy, chairman and CEO.

The changes include a number of new roles for members of the company’s management team, with the transition process beginning on 5 November.

At Gap, Stephen Sunnucks, current president of the International division, becomes global president, based in New York.

Mark Breitbard, the brand’s senior product leader in the US and Canada, takes on an expanded role based in San Francisco as president of Gap North America, reporting to Sunnucks.

Meanwhile, current Gap North America president Art Peck takes on the position of president of the newly formed Innovation, Digital Strategy and New Brands Division, and will also take charge of the Athleta and Piperlime brands.

At Banana Republic, Jack Calhoun, current president North America, will be global president, while the brand’s top merchant, Julie Rosen, takes responsibility for the brand’s North America performance, also continuing to lead global product.

Stefan Larsson started as global president of Old Navy earlier this month, and is joined full-time by Jill Stanton, who will oversee all aspects of product design, development and production.

The company’s current China team, based in Shanghai, will be overseen by CEO Murphy, while Old Navy product leader Nancy Green will assume a new role supporting China.

Finally, Toby Lenk, president of Gap’s online division, will leave the business in February.

The San Francisco based retailer earlier this month booked a 6% rise in comparable sales during September on the back of gains at its North American divisions. Net sales increased 8% to US$1.45bn for the five weeks ended 29 September, compared to $1.35bn the same period last year.

For the year-to-date its net sales have increased 6% to $9.71bn, while comparable sales are up by 5% compared to a 3% decrease last year.
