In its most recent public year (2023), this organization spent $1,664,284 more than it brought in. Its reserves stood at about 45.9 months of spending, down from 122.1 in 2011. Staff pay was 34% of spending. $5,002,968 of its net assets are donor-restricted.

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
