Under the LMEC governing documents, each member appoints two directors to sit on the LMEC governing board, one from such Member's senior management and the other from the Member's governing board (except that the President and Fellows of Harvard College may appoint an alternate in lieu of a Member of their governing board), and each corporate Member may appoint an alternate to attend and vote at meetings of the Board of Directors in the absence of either of the directors it appoints. The bylaws provide that the Directors appointed by each Member jointly have one vote, and in the event of any disagreement between such directors, the vote of such Member shall be disregarded. An appointed Director may be suspended or removed with or without cause by the Member that appointed such Director.</ExplanationTxt>

        <ExplanationTxt>LMEC is a tax-exempt organization under Section 501(c)(3) of the Internal Revenue Code (the Code) and is exempt from federal income taxes on related income pursuant to Section 501(a) of the Code. Tax-exempt organizations could be required to record an obligation for income taxes as the result of a tax position they have historically taken on various tax exposure items including unrelated business income or tax status. LMEC has evaluated the position taken on its filed tax returns. LMEC has concluded that no uncertain income tax positions exist at September 30, 2016. LMEC's tax years from 2013 through 2016 are potentially subject to examination.</ExplanationTxt>

        <ExplanationTxt>During calendar year 2015, Mr. John Aubrecht was paid by President and Fellows of Harvard College (Harvard) and leased to Longwood Medical Energy Collaborative, Inc. (LMEC) for his role as President and Executive Director of LMEC. Mr. Aubrecht commenced that role in September of 2010. The Executive Committee of LMEC serves as the Organization's Compensation Committee. The process for determining the annual compensation for LMEC's Executive Director included a comprehensive review by the Executive Committee. As part of the process of hiring Mr. Aubrecht as Executive Director, the Executive Committee consulted with senior human resources executives from two of the Member Organizations (BIDMC and Harvard) and hired an executive recruitment firm to gather comparable compensation data for experienced executives with energy business expertise and help set compensation limits. The Executive Committee reviewed and discussed the comparable compensation data and the proposed compensation terms for the Executive Director and approved the compensation arrangements for the Executive Director. The Executive Committee deliberations were documented in minutes, and the LMEC Member Organizations also ratified, approved and confirmed the hiring and compensation of the Executive Director which approval was contemporaneously documented in minutes. During the fiscal year covered by this return, the Organization's President and Executive Director, John Aubrecht, left the organization in April of 2016. Andrew Cohn assumed responsibilities as the Organization's President and Executive Director as effectuated by a signed consulting contract agreement with the Organization. The contract was approved by the Organization's Board of Directors. During the period covered by this filing, LMEC did not have any other officers or key employees that merited a compensation review process.</ExplanationTxt>
