“Ithaka's conflicts of interest policy applies to its governing board, corporate officers, key employees, and others representing the organization. Members of ithaka's governing board are required to disclose all conflicts of interest at the time they arise and annually via a written disclosure process. The audit committee is charged with reviewing conflicts of interest transactions and associated decisions and making a determination regarding any restrictions to be imposed on the transaction. Ithaka's officers and key employees are likewise required to disclose to their supervisors promptly all conflicts of interest that arise and complete an annual conflicts of interest disclosure statement.”
“The compensation and benefits committee of the board conducts an annual review of officers' compensation and the compensation of highly paid employees. As part of this review, the committee references available market data for comparable positions and internal equity considerations, and it utilizes an analysis of officer salaries using industry benchmarking data from several sources. The review process covers all officers and highly paid employees.”
“Ithaka's form 990 and financial statements are available upon request.”
“Fees for services - other as reported on form 990, part ix, line 11g represent those costs incurred related to software development which is integral to ithaka's various programs.”

“Ithaka follows the provisions of the financial accounting standards board's accounting standards codification ("asc") topic 740-10-05 relating to the accounting and reporting for uncertainty in income taxes. For ithaka, these provisions could be applicable to the incurrence of unrelated business income tax ("ubit") attributable to ithaka's shared services revenue. However, due to ithaka's general tax-exempt status, asc topic 740-10-05 has not had, and is not expected to have, a material impact on ithaka's consolidated financial statements. Ithaka is no longer subject to examination by federal and state tax authorities for years prior to 2010.”
