Note 10 - Income taxes:

 

 

The amount shown in the above table of our income tax rate reconciliation for non-U.S. tax rates represents the result determined by multiplying the pre-tax earnings or losses of each of our non-U.S. subsidiaries by the difference between the applicable statutory income tax rate for each non-U.S. jurisdiction and the U.S. federal statutory tax rate of 35%.  The amount shown on such table for incremental net tax (benefit) on earnings and losses on non-U.S. companies includes, as applicable, (i) current income taxes (including withholding taxes, if applicable), if any, associated with any current-year earnings of our non-U.S. subsidiaries to the extent such current-year earnings were distributed to us in the current year, (ii) deferred income taxes (or deferred income tax benefit) associated with the current-year change in the aggregate amount of undistributed earnings of our Canadian subsidiary, which earnings are not subject to a permanent reinvestment plan, in an amount representing the current-year change in the aggregate current income tax that would be generated (including withholding taxes, if applicable) when such aggregate undistributed earnings are distributed to us, and (iii) current U.S. income taxes (or current income tax benefit), including U.S. personal holding company tax, as applicable, attributable to current-year income (losses) of one of our non-U.S. subsidiaries, which subsidiary is treated as a dual resident for U.S. income tax purposes, to the extent the current-year income (losses) of such subsidiary is subject to U.S. income tax under the U.S. dual-resident provisions of the Internal Revenue Code.

The components of our net deferred income taxes at December 31, 2014 and 2015 are summarized in the following table.

 

 

We have substantial net operating loss (NOL) carryforwards in Germany (the equivalent of $683 million and $96 million for German corporate and trade tax purposes, respectively, at December 31, 2015) and in Belgium (the equivalent of $86 million for Belgian corporate tax purposes at December 31, 2015), all of which have an indefinite carryforward period.  As a result, we have net deferred income tax assets recognized with respect to these two jurisdictions, primarily related to these NOL carryforwards.  The German corporate tax is similar to the U.S. federal income tax, and the German trade tax is similar to the U.S. state income tax.  Prior to June 30, 2015, and using all available evidence, we had concluded no deferred income tax asset valuation allowance was required to be recognized with respect to these net deferred income tax assets under the more-likely-than-not recognition criteria, primarily because (i) the carryforwards have an indefinite carryforward period, (ii) we utilized a portion of such carryforwards during the most recent three-year period, and (iii) we expect to utilize the remainder of the carryforwards over the long term.  We had also previously indicated that facts and circumstances could change, which might in the future result in the recognition of a valuation allowance against some or all of such deferred income tax assets.  However, as of June 30, 2015, and given our operating results during the second quarter of 2015 and our expectations at that time for our operating results for the remainder of 2015, we did not have sufficient positive evidence to overcome the significant negative evidence of having cumulative losses in the most recent twelve consecutive quarters in both our German and Belgian jurisdictions at June 30, 2015 (even considering that the carryforward period of our German and Belgian NOL carryforwards is indefinite, one piece of positive evidence).  Accordingly, at June 30, 2015, we concluded that we were required to recognize a non-cash deferred income tax asset valuation allowance under the more-likely-than-not recognition criteria with respect to our German and Belgian net deferred income tax assets. Such valuation allowance aggregated $150.3 million at June 30, 2015.  We recognized an additional $8.7 million non-cash deferred income tax asset valuation allowance under the more-likely-than-not recognition criteria during the third and fourth quarters of 2015, due to losses recognized by our German and Belgian operations during such period.   In addition to the aggregate $159.0 million increase in the deferred income tax asset valuation allowance recognized as part of the provision for income taxes in 2015, the deferred income tax asset valuation allowance also increased by an aggregate of $9.8 million in 2015 due to amounts recognized in other comprehensive income.

Tax authorities are examining certain of our U.S. and non-U.S. tax returns and have or may propose tax deficiencies, including penalties and interest.  Because of the inherent uncertainties involved in settlement initiatives and court and tax proceedings, we cannot guarantee that these tax matters will be resolved in our favor, and therefore our potential exposure, if any, is also uncertain.  In 2011 and 2012 we received notices of re-assessment from the Canadian federal and provincial tax authorities related to the years 2002 through 2004.  We objected to the re-assessments and believed the position was without merit.  Accordingly, we appealed the re-assessments and in connection with such appeal we were required to post letters of credit aggregating Cdn. $7.9 million (see Note 9).  In 2014, the Appeals Division of the Canadian Revenue Authority ruled in our favor and reversed in their entirety such notices of re-assessment.  As a result, we recognized a non-cash income tax benefit of $3.0 million related to the release of a portion of our reserve for uncertain tax positions in 2014 related to the completion of this Canadian income tax audit.  In addition, the related letters of credit have been cancelled.  Also during 2014, we recognized a non-cash income tax benefit of $3.1 million related to the release of a portion of our reserve for uncertain tax positions in conjunction with the completion of an audit of our U.S. income tax return for 2009. We believe we have adequate accruals for additional taxes and related interest expense which could ultimately result from tax examinations.  We believe the ultimate disposition of tax examinations should not have a material adverse effect on our consolidated financial position, results of operations or liquidity.

We accrue interest and penalties on our uncertain tax positions as a component of our provision for income taxes.  The amount of interest and penalties we accrued during 2013, 2014 and 2015 was not material, and at December 31, 2013, 2014 and 2015, we had $3.7 million, $2.8 million and $2.3 million, respectively, accrued for interest and penalties for our uncertain tax positions.

The following table shows the changes in the amount of our uncertain tax positions (exclusive of the effect of interest and penalties discussed above) during 2013, 2014 and 2015:

 

 

If our uncertain tax positions were recognized, a benefit of $15.1 million, $8.8 million and $7.8 million would affect our effective income tax rates for 2013, 2014 and 2015 respectively.  At December 31, 2015, we currently estimate that our unrecognized tax benefits will not change materially during the next twelve months related to our prior year returns.

We file income tax returns in various U.S. federal, state and local jurisdictions.  We also file income tax returns in various non-U.S. jurisdictions, principally in Germany, Canada, Belgium and Norway.  Our U.S. income tax returns prior to 2012 are generally considered closed to examination by applicable tax authorities.  Our non-U.S. income tax returns are generally considered closed to examination for years prior to 2011 for Germany, 2012 for Belgium, 2010 for Canada and 2006 for Norway.
