Form And Line Reference	Schedule D, Part X, Line 2	FormAndLineReferenceDesc
Explanation	Uncertain tax positions The Foundation is exempt from federal income tax under Section 501(c)(3). Accounting standards prescribe a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. These standards also provide guidance on de-recognition of tax benefits, classification on the balance sheet, interest and penalties, accounting in interim periods, disclosure, and transition. The Foundation has evaluated any uncertain tax positions and related income tax contingencies and determined uncertain positions, if any, are not material to the financial statements. Penalties and interest assessed by income taxing authorities are included in operating expenses, if incurred. Tax Returns are generally subject to examination by federal and state taxing authorities for three years.	ExplanationTxt

Schedule I, Line 1

The Silverstein Foundation for Parkinsons with GBA maintains records to substantiate the funding amount, eligibility criteria and selection criteria used to award the grants. A Grant Contracting Process Summary provides detailed instructions and guidance for the Board and Scientific Advisory Board (SAB) as they seek new, cutting-edge therapeutic approaches for treating and preventing Parkinsons Disease in GBA mutation carriers. The SAB, which guides decision making in the selection process, is comprised of eleven (11) world renowned researchers and drug-developers. They are able to rapidly comb through GBA-related research to advance our goals and determine which grants shall be awarded. The Grant Contracting Process outlines the steps the Foundation takes to substantiate amounts and eligibility as follows; Primary Investigators (PI's) are asked to submit a detailed research plan and complete milestone and budget templates which are reviewed by Foundation staff and SAB members. Budget justification may be required. For private companies, high-level financial documents are requested in order to provide confirmation that the company has financial stability throughout the duration of the grant and beyond. Once all documents are received from grantee, internal review by all scientists ensures that all requests and goals are appropriate. A contract template, which includes payment schedule, is completed once all documents have been vetted by internal staff. A payment schedule is determined and payments are based upon milestones and deliverables being met. Clear go/no-go points for the research are required. Final executed contract, including budget and milestones are signed by the Foundation and the grantee, and are kept on file. Foundation personnel are assigned to oversee the progress of the grant, both scientifically and administratively. Progress updates, check-ins and reporting requirements are outlined and agreed upon in the contract and are monitored closely by personnel.

Schedule I, Line 2

Describe the Foundation's procedures for monitoring the use of grant funds. The Silverstein Foundation for Parkinson's with GBA maintains a rigorous grant management process which involves the following steps: Identify point of contact (POC) internally and communicate this to grantee. Inform grantee that they will be in touch with POC proactively on: - First month progress on recruitment and hires (clinical grant) - Monthly progress on recruitment (clinical grant) - Scheduling a three (3) month call, midpoint assessment call and final assessment meeting/call. - Submit midpoint report and final report to the POC progress against milestones. Payments will only be released if milestones are met. Grantee will need to stay in touch to share updates. Adjust payments if milestones are delayed. If work cannot continue, modification of work or early termination of grant would be required. Upon confirmation that payment can be sent, inform Foundation Treasurer (Natalie Silverstein) three (3) days in advance to issue payment. Share grantee name, amount and bank information. Track information in grants tracker, payment tab. During midpoint and final report submission, ensure all high-level data, findings and results are shared in written form, even if grantee plans to share information via phone or in person during assessment meeting. Foundation shall save all reports and final presentations in grantee's file as "reports & results".

Form 990, Part III, LINE 1, Organization's mission

CONTINUE FROM PART III: WE AGGRESSIVELY SEEK OUT NEW CUTTING EDGE THERAPEUTIC APPROACHES TREATING AND PREVENTING PARKINSON'S IN GBA MUTATION CARRIERS. THROUGH CLINICIANS, SCIENTISTS AND BIOTECH COMPANIES, WE SEEK TO ACCELERATE RESEARCH AND CLINICAL TRIALS IN AN EFFORT TO RAPIDLY BRING NEW THERAPEUTIC OPTIONS TO PATIENTS. FORM 990, PART III, LINE 4a, PROGRAM SERVICES CONTINUE FROM PART III: THE FOUNDATION PREVIOUSLY FUNDED THE FOLLOWING INITIATIVES THAT CONTINUE TO ADVANCE THE MISSION OF THE ORGANIZATION: Prevail Therapeutics, a company that the Foundation started with Asa Abeliovich, raised $200 million via private and public financing. Prevail recently announced that enrollment in the PR001 Phase 1/2 PROPEL clinical trial is progressing, patient dosing continues, and the Company is hopeful that it will remain on track to report interim data on a subset of patients in the second half of 2020. Aspen Neuroscience, which was spun out of Scripps Institute and the lab of world-renowned stem cell researcher Dr. Jean Loring, raised more than $70 million to study autologous stem cell approaches. FURTHER, THE FOUNDATION LAUNCHED THE FOLLOWING NEW INITIATIVES DURING 2019: During the third quarter of 2019, Vanqua Bio was launched, based on Foundation-funded research being conducted in the laboratory of Dr. Dimitri Krainc at Northwestern University. The company is focused on developing small molecule modulators of lysosomal targets that have genetic linkages to GBA PD. In September 2019, together with Q-State Biosciences, the Foundation launched Chamishi Therapeutics, a new drug discovery and development company focused on neurodegenerative diseases and other related disorders. The partnership will combine The Silverstein Foundation's deep scientific knowledge base with Q-State's precision medicine platform, disease-relevant cellular assays, and ASO (antisense-oligonucleotide) design capabilities. Chamishi is led by Jim Sullivan, former Vice President of Pharmaceutical Discovery at AbbVie.
