“Compensation for the organization's president and other officers is paid by southern illinois hospital services, inc. (sihs), a related tax-exempt organization. The board of trustees sets the executive compensation policy and is responsible for approval of the compensation. The governance committee is designated by the board to act as the compensation committee for matters concerning executive compensation. Each member of the committee, while considering executive compensation issues, must be an independent director, free from any conflict of interest. The committee seeks out and contracts the services of an outside, independent executive compensation consultant to advise the committee in matters of market values of comparable executive positions. The committee annually reviews all comparability data and prepares a recommendation as to the compensation package of the president/ceo for the full board. Only the full board has the authority to approve the compensation of the president/ceo. The decisions and deliberations are documented in the governance committee minutes. This process was last undertaken in june 2024. Because the organization's president and other officers are not paid by the filing organization, the form 990 instructions require this to be answered "no."”
“The members of the Governance Committee are the President, the Secretary, and the Treasurer. The Governance committee is authorized to act for the Board of Trustees in all matters as specifically authorized by resolution of the Board or when the Board of Trustees is not in session.”
“The organization's sole member is Southern Illinois Hospital Services, a related tax-exempt organization. The member has the right to elect members to the board of trustees and approve some decisions of the board.”
“The organization's sole member, Southern Illinois Hospital Services, Inc., has the exclusive right to elect Trustees to the organization's Board of Trustees”
“The organization's sole member, Southern Illinois Hospital Services (Corporate Member), has reserved powers found in the Organizations bylaws. Except for transfers identified in the budget of the Organization approved by the Corporate Member, the Organization may not transfer assets to entities other than the Corporate Member or entities that the Corporate Member controls (the "Corporate Member Affiliates"), without the approval of the Corporate Member. The Corporate Member has the right to require the Organization to transfer assets to the extent necessary to accomplish the Corporate Member's goals and objectives. The Corporate Member also has the right to require the organization to provide for the payment of all indebtedness of the Corporate Member or a Corporate Member Affiliate. The Organization cannot be required to violate its charitable purposes, the terms of any restricted gifts, or the covenants of its debt instruments in complying with any asset transfers directed by the Corporate Member. In addition, the following matters must be submitted to and receive the approval of the Corporate Member: 1. Capital expenditures in excess of $500,000; 2. The buying, selling, leasing, mortgaging or disposing of real property belonging to the Corporation or any of its subsidiaries; 3. The establishment or discontinuance of any major services; including services requiring Certificates of Need; 4. Long-Range Strategic Plans; 5. Master Facilities and Site Plans; 6. The creation or dissolution of any corporation, the sole member or majority stockholder of which is the Corporation; 7. Joint venture or affiliation agreements; 8. The incurrence of indebtedness in excess of $500,000; 9. Such other matters as may be required by law or by the Organization's Articles of Incorporation, or by its bylaws to be submitted to the Corporate Member; 10. Delegation of the functions, powers, duties and responsibilities of any officer of the Corporation, and; 11. Any other matter which may be specified from time to time by the Corporate Member. In addition, The Corporate Member retains the right to approve all changes to the organization's bylaws.”
“A draft of the Form 990 and supplemental schedules was distributed to the CEO, CFO and certain Vice-Presidents of the corporation for their review and comments. A draft copy was presented to the Finance Committee by the CFO and the organization's tax advisors for review and comments. After the review and comment period, all suggestions and comments were considered and the Form 990 was updated as appropriate. The finalized Form 990 and supplemental schedules was then presented to the Board of Trustees and a copy of the return was made available to every member of the governing body before it was filed with the IRS.”
“Annually, the General Counsel sends out a Conflict of Interest Questionnaire to each Trustee, Director, Officer, Manager and key employee to complete and return. The General Counsel then reviews these Questionnaires to determine what conflicts, real or perceived, exist. During every board meeting, the General Counsel reminds the Trustees that the Board has a conflict of interest policy, that the General Counsel has reviewed the agenda for any conflicts, but that the Trustees are obligated to give notice if a conflict has been over-looked or if a discussion or action comes before the Board which may involve or create a conflict of interest for someone. If a Trustee has a conflict of interest, the Trustee or the General Counsel discloses the conflict. The Trustee with the conflict is allowed to remain in the meeting to answer any question the Trustee may need to answer and then the conflicted Trustee is excused from the meeting. The remaining Trustees then discuss the matter further and action is taken on the matter. Finally, the conflicted Trustee is then invited back into the meeting. Interested persons may also be asked, in rare situations, to resign their position on the Board.”
“The Board of Trustees sets the executive compensation policy and is responsible for approval of the compensation. The Governance Committee is designated by the Board to act as the Compensation Committee for matters concerning executive compensation. Each member of the Committee, while considering executive compensation issues, must be an independent director, free from any conflict of interest. The Committee seeks out and contracts the services of an outside, independent executive compensation consultant to advise the Committee in matters of market values of comparable executive positions. The Committee annually reviews all comparability data and prepares a recommendation as to the compensation package of all officers for the full Board. Only the Committee will have the authority to approve the compensation of the senior management team and will report its actions to the Board. The decisions and deliberations are documented in the governance committee minutes. This process was last undertaken in June 2024.”
“The organization makes its conflict of interest policy available to the public on its website and upon request. Governing documents and financial statements are not required disclosures pursuant to Internal Revenue Code (IRC) Section 6104. These documents are not available to the public at this time.”

“The organization is included in consolidated financial statements. Below is the FIN 48 (ASC 740) footnote from those financial statements: SIHE and its affiliated organizations, with the exception of the Captive, Harrisburg Medical Center Clinic Services, LLC, HSSI and PSC, are exempt from federal income taxes under Section 501(c)(3) of the Internal Revenue Code. The Corporation realized certain income which the Internal Revenue Service considers to be unrelated business income subject to income tax. For the years ended March 31, 2025 and 2024, a minimal amount of tax was due related to these operations. The Captive is incorporated under the laws of the Cayman Islands, which impose no tax on income or capital gains. However, the Captive is subject to U.S. federal corporate taxation to the extent that it generates income that is effectively connected with a U.S. trade or business. The Captive is not engaged in any such trade or business in the U.S. PSC is a pass-through entity and its members separately account for their share of PSC's net income or loss which is allocated to the members based on the ownership percentage. Accordingly, income taxes are not provided for in the accompanying consolidated financial statements. When tax returns are filed, it is highly certain that some positions taken would be sustained upon examination by the taxing authorities, while others are subject to uncertainty about the merits of the position taken or the amount of the position that would be ultimately sustained. Examples of tax positions common to health systems include matters such as the tax-exempt entity taking a tax position that an organization is tax exempt without observing corresponding proof of tax exemption from federal and state taxing authorities and there is material net income generated by the entity or egregious compensation paid to insiders that could result in revocation of exempt status (outside the scope of intermediate sanctions excise tax penalties). The tax position is to consider that these compensatory arrangements do not jeopardize tax exemption. The benefit of a tax position is recognized in the consolidated financial statements in the period during which, based on all available evidence, management believes it is more likely than not that the position will be sustained upon examination, including the resolution of appeals or litigation processes, if any. Tax positions taken are not offset or aggregated with other positions. Tax positions that meet the "more-likely-than-not" recognition threshold are measured as the largest amount of tax benefit that is more than 50 percent likely of being realized upon settlement with the applicable taxing authority. There were no uncertain tax benefits identified and recorded at March 31, 2025 and 2024. The Corporation does not expect the total amount of unrecognized tax benefits to significantly change in the next 12 months. The Corporation would recognize interest and/or penalties related to income tax matters in miscellaneous expenses. There was no interest and/or penalties related to income tax matters identified and recorded for the years ended March 31, 2025 and 2024. Tax returns filed by the Corporation are subject to examination by the Internal Revenue Service (IRS) up to three years from the extended due date of each return. Tax returns filed by the Corporation are no longer subject to examination for the years ended March 31, 2021 and prior.”
