        <ExplanationTxt>THE COMPONENT OF TRUST I NOT SUBJECT TO COLLECTIVE BARGAINING AGREEMENTS CONSTITUTES A QUALIFIED VOLUNTARY EMPLOYEE BENEFIT ASSOCIATION UNDER SECTION 501(C)(9) OF THE INTERNAL REVENUE CODE (IRC) AND IS, THEREFORE, CONSIDERED TO BE EXEMPT FROM FEDERAL INCOME TAXES UNDER PROVISIONS OF SECTION 501(A), EXCEPT FOR ANY UNRELATED BUSINESS INCOME. SUCH UNRELATED BUSINESS INCOME ESSENTIALLY CONSISTS OF INVESTMENT INCOME AND IS SUBJECT TO UNRELATED BUSINESS INCOME TAXES BASED UPON THE CHARACTER OF THE INCOME TAXED (CAPITAL VERSUS ORDINARY). THE PLAN FILES UNRELATED BUSINESS INCOME TAX (UBIT) RETURNS IN THE U.S. FEDERAL JURISDICTION. THE PLAN IS CURRENTLY UNDER EXAMINATION BY THE IRS FOR ITS U. S. FEDERAL INCOME TAX RETURN FOR THE YEARS 2008, 2009 AND 2010. THE COMPONENT OF TRUST I SUBJECT TO COLLECTIVE BARGAINING AGREEMENTS AND TRUST III CONSTITUTE A QUALIFIED VOLUNTARY EMPLOYEE BENEFIT ASSOCIATION UNDER SECTION 501(C)(9) OF THE IRC AND ARE, THEREFORE, CONSIDERED TO BE EXEMPT FROM FEDERAL INCOME TAXES UNDER PROVISIONS OF SECTION 501(A). TRUST I AND TRUST III OBTAINED THEIR LATEST DETERMINATION LETTERS ON JUNE 22, 1977 AND NOVEMBER 22, 1993, RESPECTIVELY, IN WHICH THE INTERNAL REVENUE SERVICE (IRS) STATED THAT TRUST I AND TRUST III, AS THEN DESIGNED, WERE IN COMPLIANCE WITH THE APPLICABLE REQUIREMENTS OF THE IRC. TRUST I AND TRUST III HAVE BEEN AMENDED SINCE RECEIVING DETERMINATION LETTERS. HOWEVER, TRUST I AND TRUST III'S ADMINISTRATOR BELIEVES THAT THE PLAN AND TRUSTS ARE CURRENTLY DESIGNED AND BEING OPERATED IN COMPLIANCE WITH THE APPLICABLE REQUIREMENTS OF THE IRC. 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 (OR ASSET) IF THE PLAN HAS TAKEN AN UNCERTAIN POSITION THAT MORE LIKELY THAN NOT WOULD NOT BE SUSTAINED UPON EXAMINATION BY THE IRS. THE PLAN ADMINISTRATOR HAS ANALYZED THE TAX POSITIONS OF THE PLAN AND HAS CONCLUDED THAT AS OF DECEMBER 31, 2015, THERE IS ONLY ONE UNCERTAIN POSITION TAKEN OR EXPECTED TO BE TAKEN THAT WOULD REQUIRE RECOGNITION OF A LIABILITY AND DISCLOSURE IN THE FINANCIAL STATEMENTS. THIS POSITION RELATES TO THE "SET ASIDE". THE IRC PROVIDES THAT PASSIVE INCOME CAN BE "SET ASIDE" IF IT IS USED FOR THE PURPOSE OF THE PAYMENT OF BENEFITS OR FOR ADMINISTRATIVE COSTS RELATED TO SUCH PURPOSE. THE PLAN ADMINISTRATOR BELIEVES THE PASSIVE INCOME USED TO PAY CLAIMS INCURRED BUT NOT REPORTED CAN BE "SET ASIDE." THE PLAN RECOGNIZES INTEREST AND PENALTIES ACCRUED RELATED TO UNRECOGNIZED TAX BENEFITS IN TAX EXPENSE. THE AMOUNT OF INTEREST AND PENALTIES RECOGNIZED MAY BE AN EXPENSE OR BENEFIT DUE TO NEW OR REMEASURED UNRECOGNIZED TAX BENEFIT ACCRUALS. AT DECEMBER 31, 2015, THERE ARE NO ACCRUED INTEREST AND PENALTIES RECORDED FOR THIS ISSUE. INVESTMENT INCOME FROM THE COMPONENT OF TRUST I RELATED TO PARTICIPANTS NOT SUBJECT TO COLLECTIVE BARGAINING AGREEMENTS, AS DEFINED BY THE IRC, IS SUBJECT TO UNRELATED BUSINESS INCOME TAXES (UBIT). THE INCOME TAXES RECEIVABLE AT DECEMBER 31, 2015 AND 2014, IN THE PLAN'S STATEMENTS OF NET ASSETS AVAILABLE FOR BENEFITS RESULTS FROM TAX PAYMENTS EXCEEDING THE ACTUAL AMOUNT OF TAX LIABILITY AS OF THAT DATE. THE FUTURE TAX CONSEQUENCE ATTRIBUTED TO UNREALIZED INVESTMENT INCOME (OR LOSSES) IS REFLECTED AS A NET DEFERRED UBIT TAX LIABILITY OR A NET DEFERRED UBIT TAX ASSET IN THE PLAN'S STATEMENTS OF NET ASSETS AVAILABLE FOR BENEFITS AS THE NET TAXES ARE NOT PAYABLE OR RECEIVABLE UNTIL THE INVESTMENT INCOME OR LOSS IS REALIZED. THE COMPONENT OF TRUST I SUBJECT TO COLLECTIVE BARGAINING AGREEMENTS AND TRUST III ARE NOT SUBJECT TO UBIT.</ExplanationTxt>
