“The trust shall be administered by a board of three trustees, who shall be appointed by the umwa. The union may remove any trustee at any time. In the event of resignation, death, removal, inability or unwillingness to serve of a trustee, the union shall appoint a successor.”
“No other committees exists.”
“An electronic copy of the form 990 is supplied by the independent certified public accounting firm to the trustees for their joint review. Upon their review, any proposed changes are relayed back to the indepenent certified public acccounting firm; who upon their discussion with the trustees, make the necessary proposed changes agreed upon and resend the return for final approval for filing.”
“The organization does not make its governing documents nor its financial statements available to the public; however, they are furnished upon request to the contributing employer, participants and beneficiaries.”
“The trust terminated on 6/01/2017 and transferred all its assets and liabilities, net of $139,240,070, to the united mine workers of america prefunded benefit plan.”
“Accounting principles generally accepted in the United States of America require management to evaluate tax positions taken and recognize a tax liability if the Plan has taken an uncertain position that more likely than not would not be sustained upon examination by the Internal Revenue Service. Management has evaluated the tax positions taken by the Plan, and concluded that as of June 1, 2017, there are no uncertain positions taken or expected to be taken that would require disclosure in the financial statements. The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress.”

| IRS990ScheduleD/SupplementalInformationDetail/ExplanationTxt | 0 | Accounting principles generally accepted in the United States of America require management to evaluate tax positions taken and recognize a tax liability if the Plan has taken an uncertain position that more likely than not would not be sustained upon examination by the Internal Revenue Service. Management has evaluated the tax positions taken by the Plan, and concluded that as of June 1, 2017, there are no uncertain positions taken or expected to be taken that would require disclosure in the financial statements. The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress. |
