Explanation	CASH GRANTS: THE MUSEUM'S CASH AWARDS FALL INTO THREE CATEGORIES. A) SUBAWARDS UNDER GRANTS - THESE ARE MONIES PASSED THROUGH TO INSTITUTIONS WHO HAVE APPLIED FOR GOVERNMENT AND PRIVATE GRANTS JOINTLY WITH THE MUSEUM. THE MUSEUM MONITORS THE SUBAWARDEES' USE OF FUNDS IN ACCORDANCE WITH THE REGULATIONS GOVERNING SUCH GRANTS AND THE ADEQUACY OF THIS MONITORING IS AUDITED ANNUALLY UNDER THE PROVISIONS OF 2 CFR 200. B) PRIZES AND AWARDS - THE MUSEUM ADMINISTERS TWO MAJOR ANNUAL AWARDS FOR THE RECOGNITION OF SCIENTIFIC PUBLICATION AND COMMUNICATION. THE MUSEUM ALSO HOSTS REFEREED STUDENT COMPETITIONS FOR WHICH CASH PRIZES ARE AWARDED. AS ALL THESE AWARDS ARE HONORARIA, MONITORING OF THEIR USE IS NOT APPLICABLE. C) STIPENDS - THESE ARE PAYMENTS TO PARTICIPANTS IN PROFESSIONAL DEVELOPMENT WORKSHOPS OFFERED BY THE MUSEUM, OR IN PILOT TESTING OF MUSEUM PRODUCTS AND PROGRAMS. AS THESE PAYMENTS ARE SIMPLE FLAT STIPENDS BASED ON NUMBER OF WORKSHOP DAYS, OR ON PILOT TEST MILESTONES, MONITORING OF THEIR USE IS NOT APPLICABLE. NON-CASH GRANTS: THE MUSEUM ALSO PROVIDES SUBSTANTIAL NON-CASH "SCHOLARSHIPS" FOR REDUCED-FEE OR NO-FEE PARTICIPATION IN MUSEUM PROGRAMS FOR WHICH A FEE IS USUALLY CHARGED. FOR THESE TRANSACTIONS, NO FUNDS ARE DISBURSED TO THE GRANTEE; THEY ARE SIMPLY CHARGED LESS, OR NOT AT ALL, FOR THE PROGRAM ATTENDED. ELIGIBILITY IS DETERMINED IN A NUMBER OF WAYS, DEPENDING ON THE NATURE OF THE GRANTEE. SCHOOLS ARE EVALUATED BASED ON LOCATION IN UNDER-SERVED NEIGHBORHOODS OR BY PERCENTAGE OF FREE/REDUCED LUNCH PROGRAM STUDENTS. COMMUNITY GROUPS ARE EVALUATED ON THE BASIS OF CHARITABLE STATUS. INDIVIDUAL GRANTEES ARE EVALUATED ON THE BASIS OF INCOME OR RESIDENCE IN UNDER-SERVED AREAS. AS THE OPERATION OF THESE NON-CASH AWARDS IS ENTIRELY INTERNAL TO THE MUSEUM, MONITORING THE USE OF THE FUNDS IS ALSO ENTIRELY INTERNAL AND ACCOMPLISHED THROUGH THE MUSEUM'S OWN ACCOUNTING SYSTEM.
