This report examines the Small Business Administration's (SBA's) appropriations (new budget authority, minus rescissions and sequestration) over time, focusing on developments and trends since FY2000. It also provides total available funding (which includes carryover from the prior fiscal year, carryover into the next fiscal year, account transfers, rescissions, and sequestration) and, for entrepreneurial development noncredit programs, actual expenditures for comparative purposes. SBA appropriations, as a whole, have varied significantly from year to year since FY2000 and across all three of the agency's major spending categories: disaster assistance, business loan credit subsidies, and "other programs," a category that includes salaries and expenses, business loan administration, the Office of Inspector General, the Office of Advocacy, and entrepreneurial development programs. Overall, the SBA's appropriations have ranged from a high of $2.233 billion in FY2006 to a low of $571.8 million in FY2007. Much of this volatility is due to significant variation in appropriations for disaster assistance, which ranged from a high of $1.7 billion in FY2006 to a low of $0 in FY2009. This variation can be attributed primarily to supplemental appropriations provided to address disaster needs arising from the impact of major hurricanes, such as Hurricane Katrina and, more recently, Hurricane Sandy. The SBA's appropriations for business loan credit subsidies have also varied since FY2000, ranging from a high of $319.7 million in FY2013 ($337.3 million before sequestration and rescission) to a low of $1.3 million in FY2006 and FY2007. This variation is due to the impact of changing economic conditions on the SBA's guaranteed loan portfolios. During good economic times, revenue from SBA fees and collateral liquidation is typically sufficient to cover the costs of purchasing guaranteed loans that have defaulted. During and immediately following recessions, however, that revenue is typically insufficient to cover the costs of purchasing guaranteed loans that have defaulted. The SBA's appropriations for other programs, as a collective, have also varied since FY2000, ranging from a high of $1.6253 billion in FY2010 to a low of $455.6 million in FY2007. This variation is primarily due to congressional response to changing economic conditions. For example, Congress approved significant, temporary increases in appropriations for the SBA's other programs spending category in FY2009 and FY2010. Aside from these temporary increases, appropriations for other programs have increased at a pace that roughly matches inflation. This report provides appropriations for all 5 major components of the other programs spending category, including all 14 of the SBA's permanent entrepreneurial development programs.
