Reserve months = net assets ÷ average monthly spending; net assets count everything the organization owns beyond its debts — buildings and donor-restricted funds included, not just cash. Staff pay = salaries, wages, and officer compensation; it excludes benefits and payroll taxes. The IRS releases this data years after the fact — this organization's newest public year is 2023. Years refer to the calendar year in which the organization's fiscal year ended. Short-form filers do not publicly report donor-restricted balances or staffing costs. Source filings
