Longyear's audited financial statements, in accordance with gaap, reflect combined assets and activity of longyear and the trust. The original trust documents provided for two named trustees to manage the trust in perpetuity. While the trust has separate governing documents and distinct trustees from longyear, longyear has the right to appoint trustees of the trust and trustees of the two organizations work together as needed to fulfill the mission of the two organizations.”
