Governance Explanations

Form 990, Part VI, Section B, Line 11B

“Executive Director emails draft final copy of 990, as completed by the organization's accountant, to the current President/ interim Treasurer for review. Upon his go-ahead, the Executive Director emails final draft of 990 to all Board members for review. Each member has up to two weeks to review and reply back to Executive Director and Co-President/interim Treasurer that they have reviewed the 990 and have no issues. The Executive Director gives the accountant the go-ahead to submit, upon receiving Board member replies.”

Form 990, Part VI, Section B, Line 12C

“All Directors must sign a form acknowledging that they have received and agree to comply with the Conflict of Interest Policy. If a potential conflict of interest is identified, at any time, all Board members will be notified immediately of the situation. A Board meeting will be called immediately to review the facts and determine if conflict of interest is indeed present. A vote will be taken by a quorum of Board, who have no direct or indirect interest in the transaction, and will approve/not approve the transaction in question.”

Form 990, Part VI, Section B, Line 15A

“Executive Director's compensation is determined by current comparable salaries of other nonprofit Executive Directors, having similar missions.”

Form 990, Part VI, Section C, Line 19

“No documents available to the public.”

IRS990/Desc0General Programs - Cornerstones in collaboration with the Association of Rural and Small libraries conducted an evaluation and held interviews with their membership to explore how public libraries support community resilience on issues like natural disasters, food insecurity, public health, as examples. Over 353 librarians completed the survey and 12 librarians participated in interviews. The results and recommendations, from this survey, will be used by the organization to create a new programs and services starting in the new fiscal year FY 2025-2026. Though Cornerstones has discontinued both the Library Telescope Program and the NLM_Cornerstones of Science Test The Waters Kit there continues to be residual expenses in order to support those libraries, to replace pieces, who loan these tools out to the public. Cornerstones will continue to create NIght Sky BackPacks, in special circumstances (e.g. as an honor or award) to libraries.

IRS990ScheduleO/SupplementalInformationDetail/ExplanationTxt0Executive Director emails draft final copy of 990, as completed by the organization's accountant, to the current President/ interim Treasurer for review. Upon his go-ahead, the Executive Director emails final draft of 990 to all Board members for review. Each member has up to two weeks to review and reply back to Executive Director and Co-President/interim Treasurer that they have reviewed the 990 and have no issues. The Executive Director gives the accountant the go-ahead to submit, upon receiving Board member replies.
IRS990ScheduleO/SupplementalInformationDetail/ExplanationTxt1All Directors must sign a form acknowledging that they have received and agree to comply with the Conflict of Interest Policy. If a potential conflict of interest is identified, at any time, all Board members will be notified immediately of the situation. A Board meeting will be called immediately to review the facts and determine if conflict of interest is indeed present. A vote will be taken by a quorum of Board, who have no direct or indirect interest in the transaction, and will approve/not approve the transaction in question.
IRS990ScheduleO/SupplementalInformationDetail/ExplanationTxt2Executive Director's compensation is determined by current comparable salaries of other nonprofit Executive Directors, having similar missions.
