“As a cooperative, Wolverine is owned by its members.”
“Each member's board appoints two of its directors to represent them on Wolverine's board.”
“Wolverine's Board of Directors is authorized to make most business decisions. However, certain key matters require approval from Wolverine's members, including: (1) amendments to the Articles of Incorporation; (2) amendments or repeals of any bylaw provisions adopted by the members that address membership classifications, qualifications, director terms or classifications, quorum requirements for meetings, procedures for amending the bylaws, or provisions related to property interests; and (3) approval of any other bylaw changes passed by a two-thirds vote of the full Board of Directors.”
“Before filing Form 990, the following reviews were conducted: the Vice President, Accounting and Finance and Controller conducted a detailed review, along with Wolverine's external accounting firm. The CEO reviewed the general content of the form. Subsequently, the Audit Committee reviewed the Form 990, which was also distributed to all Board members for their individual review.”
“A conflict-of-interest statement is reviewed annually, and all directors, officers, and key employees are required to complete an annual disclosure questionnaire. Any potential conflicts identified are reported to the Board, which is responsible for determining whether a conflict exists and how it should be addressed. Individuals involved in a potential conflict are recused from any related voting decisions.”
“The Board reviews and approves the CEO's compensation annually, using information from an independent consultant and national benchmarking data, which includes compensation data from various national surveys, including those for generation and transmission cooperatives. This process was last conducted in 2024.”
“Salaries for all non-union employees are set annually following a formal performance evaluation. Salary ranges are reviewed each year to maintain internal pay equity and external competitiveness. Compensation surveys are conducted every two years and used to inform the determination of salary ranges for non-union employees. The most recent review took place in 2024.”
“The Form 990 is available upon request. However, the organization does not make its governing documents, conflict of interest policy, or financial statements publicly available.”
“The compensation reported in Part VII for the Executive Vice President represents a full-time position; however, the majority of his time was allocated to unrelated organizations-Michigan Electric Cooperative Association and Wolverine Power Marketing Cooperative, Inc.-as well as to a related organization, Spartan Renewable Energy, Inc., under management services agreements.”
“Other - Total Revenue: 31524, Related or Exempt Function Revenue: 31212, Unrelated Business Revenue: 0, Revenue Excluded from Tax Under Sections 512, 513, or 514: 312; - Total Revenue: , Related or Exempt Function Revenue: , Unrelated Business Revenue: , Revenue Excluded from Tax Under Sections 512, 513, or 514: ;”
“Recognition of post-retirement liabilities - 315544; Allocation of patronage capital - 22481681; Total - 22797225;”
“Wolverine and Peninsula are not-for-profit corporations, generally exempt from income tax under Section 501(c)(12) of the Internal Revenue Code. However, activities with non-member customers are subject to federal income taxes. Wolverine and Peninsula had no federal income tax liability as of December 31, 2024, or 2023. Spartan applies the liability method for accounting for income taxes, under which deferred tax assets and liabilities are calculated based on differences between the financial reporting and tax basis of assets and liabilities that will result in future taxable or deductible amounts. These deferred tax amounts are determined using enacted tax laws and rates applicable to the periods when the temporary differences are expected to impact taxable income. Valuation allowances are recorded when necessary to adjust deferred tax assets to the amount expected to be realized. Income tax expense represents the tax payable or refundable for the period, adjusted for any changes in deferred tax assets and liabilities during that time. Uncertain tax positions are recognized and measured in accordance with the provisions outlined in FASB ASC 740. A tax position is recognized as a benefit only if it is "more likely than not" that the position would be upheld in a tax examination, which is assumed to occur. The recognized amount is the largest tax benefit that has more than a 50% likelihood of being realized upon examination. For tax positions that do not meet the "more likely than not" threshold, no tax benefit is recorded. Spartan is subject to federal income tax. Wolverine and both of its subsidiaries are subject to the Michigan Corporate Income Tax. However, for cooperatives (Wolverine and Peninsula), only activities involving non-member customers are taxable. Wolverine files a unified tax return. With a few exceptions, Wolverine is no longer subject to examination by taxing authorities for years on or before 2020. Wolverine does not anticipate any significant changes in the total amount of unrecognized tax benefits over the next 12 months. Wolverine accounts for interest and/or penalties related to income tax matters as interest expense and income tax expense, respectively. As of December 31, 2024, and 2023, Wolverine did not have any amounts accrued for interest or penalties.”
