I'm guessing they are a 501C3 and "Answer:

"Indeed. Nonprofits are required to submit their financial statements and other information -- including the salaries of directors, officers, and key employees -- to the IRS. (For information on who is considered a key employee, see IRS Form 990 and its instructions.)

The IRS and nonprofits themselves are required to disclose the information on Form 990 to anyone who asks. Nonprofits must allow public inspection of these records during regular business hours at their principal offices. However, many people won't even need to ask -- a number of websites make Forms 990 available for the searching, including the Foundation Center at http://fdncenter.org and GuideStar at www.guidestar.org."

So it's likely very easy for you to inspect their finances if you so desire.
