_______________________________________ Note (A) For accounts receivable, amounts comprise currency translation adjustments. For deferred tax valuation allowance in 2013, 2012 and 2011, amounts relate primarily to changes in foreign tax credit carryforwards and foreign currency differences recorded through other comprehensive income. Note (B) For accounts receivable, amounts represent excess of uncollectible balances written off over recoveries of accounts previously written off. For deferred tax valuation allowance, the decrease in 2013 relates primarily to decreases in foreign tax loss carryforwards, while in 2012 and 2011 the reductions relate primarily to a decrease of recorded foreign tax credit and research and development tax credits.
