of temporary differences between the financial reporting and tax bases of assets and liabilities, and for operating losses and tax credit carryforwards. Deferred tax assets and liabilities are measured using the currently enacted tax rates that apply to taxable income in effect for the years in which those tax assets are expected to be realized or settled. The Company records a valuation allowance to reduce deferred tax assets to the amount that is believed more likely than not to be realized. 

The Company only recognizes the tax benefit from an uncertain tax position if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such positions are then measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. 

Management believes it is more likely than not that forecasted income, including income that may be generated as a result of certain tax planning strategies, together with future reversals of existing taxable temporary differences, will be sufficient to fully recover the deferred tax assets. In the event that the Company determines all or part of the net deferred tax assets are not realizable in the future, the Company will make an adjustment to the valuation allowance that would be charged to earnings in the period such determination is made. In addition, the calculation of tax liabilities involves significant judgment in estimating the impact of uncertainties in the application of GAAP and complex tax laws. Resolution of these uncertainties in a manner inconsistent with management’s expectations could have a material impact on the Company’s financial condition and operating results. 

Legal and Other Contingencies 

As discussed in Part I, Item 3 of this Form 10-K under the heading “Legal Proceedings” and in Note 8 “Commitments and Contingencies” in Notes to Consolidated Financial Statements, the Company is subject to various legal proceedings and claims that arise in the ordinary course of business. In accordance with GAAP, the Company records a liability when it is probable that a loss has been incurred and the amount is reasonably estimable. There is significant judgment required in both the probability determination and as to whether an exposure can be reasonably estimated. In management’s opinion, the Company does not have a potential liability related to any current legal proceedings and claims that would individually or in the aggregate materially adversely affect its financial condition or operating results. However, the outcomes of legal proceedings and claims brought against the Company are subject to significant uncertainty. Should the Company fail to prevail in any of these legal matters or should several of these legal matters be resolved against the Company in the same reporting period, the operating results of a particular reporting period could be materially adversely affected.
