(Reuters) - Visa Inc (N:V), the world's largest credit and debit card company, said it might have to pay more than $10 billion (6.39 billion pounds) to buy its London-based European licensee, Visa Europe Ltd, if its owners exercise their option to sell it.
Visa might issue debt or equity, or need third-party financing, to fund the purchase of Visa Europe, it said in an annual filing with regulators.
Visa Europe is owned and operated by more than 3,700 European financial institutions.
