        <ExplanationTxt>ACCOUNTING PRINCIPLES GENERALLY ACCEPTED IN THE UNITED STATES OF AMERICA REQUIRE PLAN MANAGEMENT TO EVALUATE 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 U.S. FEDERAL, STATE, OR LOCAL TAXING AUTHORITIES. THE PLAN IS SUBJECT TO ROUTINE AUDITS BY TAXING JURISDICTIONS; HOWEVER, THERE ARE CURRENTLY NO AUDITS FOR ANY TAX PERIODS IN PROGRESS. TYPICALLY, PLAN TAX YEARS WILL REMAIN OPEN FOR THREE YEARS; HOWEVER; THIS MAY DIFFER DEPENDING UPON THE CIRCUMSTANCES OF THE PLAN.</ExplanationTxt>
