        <ReturnReference>PART X, LINE 2:</ReturnReference>
        <Explanation>AAR IS EXEMPT FROM FEDERAL INCOME TAXES UNDER SECTION 501(C)(6) OF THE IRC. HOWEVER, AAR IS SUBJECT TO FEDERAL INCOME TAXES FOR ACTIVITIES THAT ARE UNRELATED TO ITS TAX-EXEMPT FUNCTION. RRF IS INCORPORATED UNDER IRC SECTION 501(C)(3) AS A TAX-EXEMPT ORGANIZATION AND IS FURTHER CLASSIFIED AS A PUBLIC CHARITY UNDER SECTION 509(A)(1) OF THE IRC; HOWEVER, RRF IS SUBJECT TO FEDERAL INCOME TAXES FOR ACTIVITIES THAT ARE UNRELATED TO ITS TAX-EXEMPT FUNCTION. AAR AND RRF, AS TAX EXEMPT ORGANIZATIONS, FILE AN INFORMATION RETURN, FORM 990-RETURN OF ORGANIZATION EXEMPT FROM INCOME TAX, AND TO THE EXTENT OF ANY UNRELATED ACTIVITIES TO THEIR TAX-EXEMPT FUNCTION, FILE FORM 990-T-RETURN OF ORGANIZATION BUSINESS INCOME TAX RETURN. TTCI AND RAILINC FILE SEPARATE FEDERAL AND STATE INCOME TAX RETURNS. ACCORDINGLY, AMOUNTS REPORTED IN THE ACCOMPANYING CONSOLIDATED FINANCIAL STATEMENTS REPRESENT THE COMBINED INCOME TAX ACCOUNTS OF AAR, TTCI, RAILINC, AND RRF. DEFERRED TAX ASSETS AND LIABILITIES ARE RECOGNIZED FOR THE FUTURE TAX CONSEQUENCES ATTRIBUTABLE TO DIFFERENCES BETWEEN THE FINANCIAL STATEMENT CARRYING AMOUNTS OF EXISTING ASSETS AND LIABILITIES AND THEIR RESPECTIVE TAX BASES AND OPERATING LOSS AND TAX CREDIT CARRYFORWARDS. DEFERRED TAX ASSETS AND LIABILITIES ARE MEASURED USING ENACTED TAX RATES EXPECTED TO APPLY TO TAXABLE INCOME IN THE YEARS IN WHICH THOSE TEMPORARY DIFFERENCES ARE EXPECTED TO REVERSE. IF APPROPRIATE, DEFERRED TAX ASSETS ARE REDUCED BY A VALUATION ALLOWANCE, WHICH REFLECTS EXPECTATIONS OF THE EXTENT TO WHICH SUCH ASSETS WILL BE REALIZED. THE ASSOCIATION FOLLOWS THE CODIFICATION TOPIC, INCOME TAXES, WHICH ADDRESSES THE DETERMINATION OF WHETHER TAX BENEFITS CLAIMED OR EXPECTED TO BE CLAIMED ON A TAX RETURN SHOULD BE RECORDED IN THE FINANCIAL STATEMENTS. UNDER THIS GUIDANCE, THE ASSOCIATION MAY RECOGNIZE THE TAX BENEFIT FROM AN UNCERTAIN TAX POSITION ONLY IF IT IS MORE LIKELY THAN NOT THAT THE TAX POSITION WILL BE SUSTAINED ON EXAMINATION BY TAXING AUTHORITIES, BASED ON THE TECHNICAL MERITS OF THE POSITION. THE TAX BENEFITS RECOGNIZED IN THE FINANCIAL STATEMENTS FROM SUCH A POSITION ARE MEASURED BASED ON THE LARGEST BENEFIT THAT HAS A GREATER THAN 50% LIKELIHOOD OF BEING REALIZED UPON ULTIMATE SETTLEMENT. THE GUIDANCE ON ACCOUNTING FOR UNCERTAINTY IN INCOME TAXES ALSO ADDRESSES DE-RECOGNITION, CLASSIFICATION, INTEREST AND PENALTIES ON INCOME TAXES, AND ACCOUNTING IN INTERIM PERIODS. MANAGEMENT EVALUATED THE ASSOCIATION'S PRECONSOLIDATED TAX POSITIONS AND CONCLUDED THAT THE ASSOCIATION HAS TAKEN NO UNCERTAIN TAX POSITIONS THAT REQUIRE ADJUSTMENT TO THE FINANCIAL STATEMENTS TO COMPLY WITH THE PROVISIONS OF THIS GUIDANCE. GENERALLY, THE ASSOCIATION IS NO LONGER SUBJECT TO INCOME TAX EXAMINATIONS BY THE U.S. FEDERAL, STATE, OR LOCAL TAX AUTHORITIES FOR YEARS BEFORE 2009.</Explanation>
