Once qualified, the Plan is required to operate in conformity with the Code to maintain its qualified status. Subsequent to receiving this determination by the IRS, the Plan was amended and restated.

Accounting principles generally accepted in the United States require plan management to evaluate uncertain tax positions taken by the Plan and recognize a tax liability if the Plan has taken an uncertain position that more likely than not would not be sustained upon examination by the IRS. Plan management has analyzed the tax positions taken by the Plan and has concluded that there are no uncertain positions taken or expected to be taken. The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress.
