For fiscal year 2014, we recorded a valuation allowance of $10.3 million on net deferred tax assets primarily related to our United States net operating loss carry forward. The gross amount of federal net operating loss carry forwards as of September 30, 2014 is estimated to be $159.3 million, which will begin to expire in 2025. Management does not expect that our tax credit carry forward of $1.2 million will be utilized to offset future tax obligations before the credits begin to expire in 2015. Thus, a corresponding valuation allowance of $1.2 million is recorded as of September 30, 2014.

We have approximately $19.6 million of windfall tax benefits from previous stock option exercises that have not been recognized as of September 30, 2014. This amount will not be recognized until the deduction would reduce our United States income taxes payable. At such time, the amount will be recorded as an increase to paid-in-capital. We apply the “with-and-without” approach when utilizing certain tax attributes whereby windfall tax benefits are used last to offset taxable income.

We do not record federal income taxes on the undistributed earnings of our foreign subsidiaries that we consider to be indefinitely reinvested in foreign operations. The cumulative amount of such undistributed earnings was approximately $2.4 billion at September 30, 2014. If these earnings were distributed, we estimate approximately $450 million in additional taxes would be incurred. These earnings could also become subject to additional taxes under the anti-deferral provisions within the U.S. Internal Revenue Code. However, we believe this is highly unlikely given our current structure and have not provided deferred income taxes on these foreign earnings as we consider them to be permanently invested abroad.

We record estimated accrued interest and penalties related to uncertain tax positions in income tax expense. At September 30, 2014, we had approximately $12.3 million of reserves for uncertain tax positions, including estimated accrued interest and penalties of $3.3 million, which are included in Other Long Term Liabilities in the Consolidated Balance Sheet. All $12.3 million of the net uncertain tax liabilities would affect the effective tax rate if recognized.

A summary of activity related to the net uncertain tax positions including penalties and interest for fiscal year 2014 is as follows:



	Liability for Uncertain
(In thousands)	Tax Positions
Balance at October 1, 2013	$	7,711
Increases as a result of tax positions taken during the current period	1,224
Increases as a result of tax positions taken in prior periods	5,546
Decreases due to the lapse of the applicable statute of limitations	(2,183		)
Balance at September 30, 2014	$	12,298

We believe that it is reasonably possible that approximately $1.2 million of our remaining unrecognized tax benefits may be recognized by the end of fiscal year 2015 as a result of a lapse of the statute of limitations.

Our United States tax returns for fiscal year 2010 and subsequent years remain subject to examination by tax authorities. As we conduct business globally, we have various tax years remaining open to examination in our international tax jurisdictions, including tax returns in Australia for fiscal years 2008 through 2013, as well as returns in Equatorial Guinea for calendar years 2010 through 2013. Although we cannot predict the outcome of ongoing or future tax examinations, we do not anticipate that the ultimate resolution of these examinations will have a material impact on our consolidated financial position, results of operations or cash flows.

We have historically earned most of our operating income in certain nontaxable and deemed profit tax jurisdictions, which significantly reduced our effective tax rate for fiscal years 2014, 2013 and 2012 when compared to the United States statutory rate. There were no significant transactions that materially impacted our effective tax for fiscal years 2014, 2013 or 2012. The differences between the United States statutory and our effective income tax rate are as follows:



	Fiscal 2014		Fiscal 2013		Fiscal 2012
Statutory income tax rate	35	%	35	%	35	%
Resolution of prior period tax items	—		—		(3	)
Increase in tax rate resulting from:
Valuation allowance	2		1		4
Increases to the reserve for uncertain tax positions	1		—		—
Decrease in tax rate resulting from:
Foreign tax rate differentials, net of foreign tax credit utilization	(24	)	(23	)	(23	)
