The tax effects of significant temporary differences representing net deferred tax assets and liabilities consisted of the following at December 31, 2017 and 2016:

In accordance with ASC Topic 740, we analyzed our valuation allowance at December 31, 2017 and determined that, based upon available evidence, it is more likely than not that certain of our deferred tax assets will be realized and, as such, has removed any valuation allowance against certain deferred tax assets.  

The aggregate changes in the balance of gross unrecognized tax benefits (included as part of accrued expenses in the accompanying financial statements), which excludes interest and penalties, are as follows as of and for the years ended December 31, 2017 and 2016:

Our total liability for unrecognized gross tax benefits was $44,488 as of December 31, 2017, which, if ultimately recognized, would impact the effective tax rate in future periods. We are subject to examination by the Internal Revenue Service for fiscal years 2014 and thereafter.  For states within the U.S. in which we conduct significant business, we generally remain subject to examination for fiscal years 2014 and thereafter, unless extended for longer periods under state laws. We have no accrual for interest or penalties related to uncertain tax positions at December 31, 2017 and 2016, and did not recognize interest or penalties in the statements of operations during the years ended December 31, 2017 and 2016.

As of December 31, 2017, we expected to use our foreign tax credits of $51,679 to offset federal income tax owed in 2017.
