Money made simple

Pay context: The highest compensation shown in this filing is $376,275 for DR ROBERT M HAUSER (CEO). Compare pay with organizations of similar size and complexity.

Financial picture
A plain-language look at the latest Form 990 figures available. These numbers help you ask better questions; they do not, by themselves, rate whether a charity is good or bad.
How each $100 of revenue was used
The large number compares each expense with revenue. The smaller number shows its share of total expenses.
Gray means reported revenue left after expenses for this filing year. It does not necessarily mean cash sitting in a bank account.
Has the pattern changed?
Colored bars = expense mix: how each year’s expenses were divided. Total expenses vs. revenue shows whether the charity spent less or more than it received. The current filing is first.
Money in and money out
