        <ReturnReference>PART X, LINE 2:</ReturnReference>
        <Explanation>THE SOCIETY IS A NOT-FOR-PROFIT CORPORATION AND IS EXEMPT FROM TAX UNDER THE PROVISIONS OF INTERNAL REVENUE CODE SECTION 501(C)(6). ACCOUNTING PRINCIPLES GENERALLY ACCEPTED IN THE UNITED STATES OF AMERICA REQUIRE MANAGEMENT TO EVALUATE TAX POSITIONS TAKEN BY THE SOCIETY AND RECOGNIZE A TAX LIABILITY IF THE SOCIETY HAS TAKEN AN UNCERTAIN POSITION THAT MORE LIKELY THAN NOT WOULD NOT BE SUSTAINED UPON EXAMINATION BY THE IRS OR OTHER APPLICABLE TAXING AUTHORITIES. MANAGEMENT HAS ANALYZED THE TAX POSITIONS TAKEN BY THE SOCIETY AND HAS CONCLUDED THAT AS OF DECEMBER 31, 2012 AND 2011, THERE ARE NO UNCERTAIN POSITIONS TAKEN OR EXPECTED TO BE TAKEN THAT WOULD REQUIRE RECOGNITION OF A LIABILITY OR DISCLOSURE IN THE FINANCIAL STATEMENTS. THE SOCIETY IS SUBJECT TO ROUTINE AUDITS BY TAXING JURISDICTIONS; HOWEVER, THERE ARE CURRENTLY NO AUDITS FOR ANY TAX PERIODS IN PROGRESS. MANAGEMENT BELIEVES IT IS NO LONGER SUBJECT TO INCOME TAX EXAMINATIONS FOR YEARS PRIOR TO 2009.</Explanation>
