List Methodology, Limitations and Disclaimer

These numbers are from regulatory filings, including Form 990, prepared by the covered organizations. Regulatory filings are prepared by individuals and service providers at the organizations, and are therefore inherently flawed. Not all foundations and endowments make regulatory filings, and those are not accounted for in this list. This data set is provided as-is, free of charge and for informational purposes only. Do not rely upon this list for any investment or contribution decision. For the most up-to-date information about a covered organization, please search the institutional investor database or contact the organization directly.

Financial Data

Year-End 2013

Financial data is derived from, among other places, the IRS Form 990 filed by each covered organization. Because exempt organizations only file Form 990 at the close of their fiscal year, the list below is current only through the end of 2013.

Gross Assets

The list is organized by gross assets for comparison with other entities covered in our special reports. Measuring gross assets may significantly inflate an organization's "size" by failing to adjust for fully-secured liabilities, such as mortgages on development real estate.
