        <ReturnReference>FIN 48 (ASC 70) FOOTNOTE</ReturnReference>
        <Explanation>In July 2006, the Financial Accounting Standards Board ("FASB") issued guidance that clarifies the accounting for uncertainty in income taxes recognized in an enterprise's financial statements. HIMSS adopted this new guidance as of July 1, 2009. This guidance clarifies the accounting for uncertainty in tax positions taken or expected to be taken in a tax return, including issues relating to financial statement recognition and measurement. This guidance provides that the tax effects from an uncertain tax position can be recognized in the financial statements only if the position is more likely than not to be sustained if the position were to be challenged by the taxing authority. The assessment of the tax position is based solely on the technical merits of the position, without regard to the likelihood that the tax position may be challenged. HIMSS and the Foundation are exempt from income tax under internal revenue code section 501(c)(6) and 501(c)(3), respectively, though it is subject to tax on income unrelated to its exempt purposes, unless that income is otherwise excluded by the internal revenue code. The tax years ending 2008, 2009, and 2010 are still open to audit for both federal and state purposes. The adoption of this guidance did not have any impact on HIMSS' financial statements.</Explanation>

        <ReturnReference>WRITTEN CONFLICT OF INTEREST POLICY</ReturnReference>
        <Explanation>Board members and key employees are annually required to complete a conflict of interest disclosure statement. The President/CEO reviews each statement of disclosure for any set of facts or circumstances that may reflect an actual, potential or apparent conflict of interest. The President/CEO may request the assistance of legal counsel to identify potential conflicts. If the President/CEO identifies an actual, potential, or apparent conflict of interest with respect to an officer, director, nominee for director, nominee for an elected position and nominee for appointment to the board, he/she must pursue resolution of such conflict of interest or challenge in accordance with Article 10, Section 10.3 of the HIMSS Bylaws. For the organization's employees, the President/CEO may take one of the following actions to resolve such conflict or challenge: - waive the conflict of interest as unlikely to affect disclosing party's ability to act in the best interests of the organization; - determine that the disclosing party should be recused from all deliberation and decision-making related to the particular transaction or relationship that gives rise to the conflict of interest. This course of action should apply particularly when the transaction or relationship is one which presents a conflict only with respect to one or two discrete programs or activities; or - recommend that the disclosing party should resign from his or her employment. This course of action should apply when the conflict is so pervasive that the disclosing party would likely seldom, if ever be able to act solely in the best interest of the organization.</Explanation>
