During 2011 and 2010, the Company's valuation allowance provided against its U.S. net deferred tax asset increased by $0.6 million and $18.8 million, respectively, primarily related to U.S. net operating losses incurred in 2011 and 2010 for which utilization is uncertain and, in 2011, the change in deferred taxes on unrealized gain on marketable securities.

As of December 31, 2011, the Company has a U.S. Federal net operating loss ("NOL") carryforward of approximately $223.3 million which can be used to offset U.S. income taxes payable in future years. This U.S. NOL carryforward will expire in periods beginning 2025 through 2031. As of December 31, 2011, the Company has an alternative minimum tax (AMT) credit carryforward of approximately $1.8 million which can be used to offset regular U.S. Federal income taxes payable in future years and which has an indefinite carryforward period. As of December 31, 2011, the Company has Canadian NOL carryforwards of approximately $1.4 million (Canadian) which can be used to offset Canadian income taxes payable in future years. These Canadian NOL carryforwards will expire in 2029.

In February 2006, Olympic Seismic Ltd. ("Olympic"), a wholly owned subsidiary of the Company, was notified by Canada Revenue Agency ("CRA") that CRA was going to perform an audit of certain aspects of Olympic's tax returns for the years 2003 and 2004. In February 2009, CRA notified the Company that the audit was expanded to include years from 2005 through 2007. In April 2011, the Company received notification that CRA concluded their audits, disallowing Olympic's deductions for certain royalties payable to the Company's U.S. entities for years 2003 to 2007. Olympic and the Company object to and are appealing the audit results. As a condition to appeal the audit results, Olympic was required to pay $7.6 million (Canadian) to CRA and did so in May 2011 and made an additional $0.1 million payment in the third quarter of 2011. These payments, which included amounts for taxes, penalties and interest assessed by CRA, have been shown as income tax payments in the Consolidated Statement of Cash Flows because the amounts paid can be applied interchangeably to the amounts which may ultimately be due to CRA. As of December 31, 2011, the appeal process has not been concluded. The Company has recorded liabilities associated with potential adjustments that may occur as a result of the appeal based on management's assessment of the probability of the outcome of the appeal, net of certain payments made to CRA. See "Uncertain Tax Benefits" below.

Uncertain Tax Benefits

The Company accounts for income taxes in accordance with ASC Topic 740, "Income Taxes," which prescribes a minimum recognition threshold a tax position must meet before being recognized in the financial statements. A reconciliation of the beginning and ending gross unrecognized tax benefits is as follows (in thousands):


	Year Ended December 31,
	2011			2010		2009
Balance at beginning of year	$	6,151		$	5,545	$	4,859
Additions based on prior year tax positions		—			310		275
Reductions in tax positions due to a lapse in statute		—			—		(365	)
Foreign currency translation		(135	)		296		776

Balance at end of year	$	6,016		$	6,151	$	5,545

As of December 31, 2011, approximately $6.0 million of the total unrecognized tax benefits would impact the effective income tax rate, if recognized in future periods. In addition, as of December 31, 2011, the Company has recorded $5.9 million in related assets which are fully offset with a valuation allowance.

Uncertain tax positions are reflected as income tax assets and liabilities. Income tax-related interest and penalty expenses are recorded as a component of income tax expense. As of December 31, 2011, we had $0.5 million of

accrued interest and $1.0 million of accrued penalties. As of December 31, 2010, we had $0.3 million of accrued interest and $1.0 million of accrued penalties. Income tax expense (benefit) for the years ended December 31, 2011, 2010 and 2009 included $0.2 million, $(0.2) million and $0.1 million, respectively, related to interest and penalties on unrecognized tax benefits.

With few exceptions, the Company is no longer subject to U.S. Federal, state and local, or non-U.S. income tax examinations by tax authorities for years prior to 2007, 2007 and 2004, respectively.
