We invite all of our sponsors, partners, and members of the community to learn more about how our organization operates, the impact of our efforts, our financial position, and our nonprofit status.
COS is governed by board-adopted by-laws. View our Financial Conflict of Interest Policy.
Our 501(c)(3) status allows for charitable contributions to be tax deductible.
Dedication to ensuring our user’s security and confidentiality while utilizing COS services is a top priority. One way we do this is by publishing our practices in our Account and Security Page. COS has been very fortunate to receive increasing sponsorship each subsequent year, and has used these new investments to grow programs and operations in pursuit of our mission. Our community has responded enthusiastically to new tools and services and we are now pursuing strategies to sustain these services as public goods.
The above revenue figures include Operating Revenue as well as Grant Pass-through Funds. Financial details showing a breakdown of the history of our funding by program, type, and funder from 2013 to 2022 can be found on the OSF here.
