As a condition of receiving Federal awards or grants, recipients must agree to comply with the applicable laws and regulations related to the program and its agency, as well as any provisions included in the contracts and grant agreements entered between the recipient and the agency. Failure to do so may lead to sanctions, including fines and penalties, exclusion or suspension from participating in federal assistance programs and activities, and/or criminal charges. Most federal program regulations for which agencies and recipients must always comply are compiled in the Code of Federal Regulations, with summaries and guidance for these regulations contained in OMB Circular letters.
