Undistributed earnings of our foreign subsidiaries amounted to approximately $1,381 million as of March 31,
2013. Those earnings are considered to be indefinitely reinvested and, accordingly, no U.S. income taxes have
been provided thereon. Upon distribution of those earnings in the form of dividends or otherwise, we would be
subject to both U.S. income taxes (subject to an adjustment for foreign tax credits) and withholding taxes payable
to various foreign countries. It is not practicable to determine the income tax liability that might be incurred if
these earnings were to be distributed.
The components of net deferred tax assets, as of March 31, 2013 and 2012 consisted of (in millions):

The valuation allowance increased by $23 million in fiscal year 2013, primarily due to the increase in deferred
tax assets for U.S. tax losses and tax credits that are not currently considered to be more likely than not to be
realized.
