Wesfarmers Ltd chief executive Richard Goyder says the sale of assets is not required for the company to focus on its $20 billion Coles business. Mr Goyder said on Sunday the company did not need to sell assets despite this year having to refinance $4 billion of debt accrued from the Coles transaction. "We don't need to sell an asset," he told ABC television. "We may in the future, we may not ... but we don't feel compelled to do it," he added. Wesfarmers' diversified portfolio includes, coal, hardware, insurance energy, chemical and safety products.
