Return Reference	Explanation
Part V, Line 4: Intended uses of the endowment fund.	SDRI has a policy of appropriation for distribution each year a prudent portion of earnings from endowment assets. In establishing this policy, SDRI considered the long-term expected return on its endowment. accordingly, over the long-term, SDRI expects its spending policy to allow SDRI to conduct diabetes research. This is consistent with SDRI's objective to maintain the purchasing power of the endowment assets held in perpetuity as well as to provide additional real growth the new gifts.
Part X : FIN48 Footnote	SDRI is organized as a California nonprofit corporation and has been recognized by the IRS as exempt from federal income taxes under Internal Revenue Code (IRC)Section 501(a) as an organization described in IRC Section 501(c)(3) and qualifies for the charitable contribution deduction under IRC Section 170(b)(1)(A)(vi) and has been determined not to be a private foundation under IRC Section 509(a)(2). SDRI is annually required to file a Return of Organization Exempt from Income Tax (Form990) with the IRS. In addition, SDRI is subject to income that is derived from business activities that are unrelated to its exempt purpose. Management has determined SDRI is not subject to unrelated business income tax and has not filed an Exempt Organization Business Income Tax Return (Form 990-T) with the IRS.SDRI tax filings are subject to examination by the IRS, generally for three years after they are filed. SDRI is not aware of any activities that would jeopardize its tax exempt status.
