[1] The put option is exercisable at any time at the sole discretion of Visa Europe with payment required 285 days thereafter. Classification in current liabilities is not an indication of management’s expectation of exercise and simply reflects the fact that the obligation resulting from the exercise of the instrument could become payable within 12 months.

[2] The increase in current accrued income taxes is primarily related to current income taxes accrued in the first quarter of fiscal 2014, but payable in the second quarter of fiscal 2014.
