        <ExplanationTxt>The compensation for the Chief Executive Officer and the Chief Financial Officer was determined by the related organization: American Association of Neurosurgeons, Inc. The following process was used: The Chief Executive Officer's annual compensation is subject to the provisions in their employment contract: the Executive shall receive a base salary, paid in accordance with the Association's normal payroll practices. Effective as of January 1, 2016, the Executive's base salary shall be at an annual rate of $325,000, and shall increase three percent (3%) on January 1st of each year. In addition, during the period of November 1, 2018 through December 31, 2018, the Association and the Executives agreed to meet in good faith to renegotiate the Executive's base salary to determine any other appropriate increase. The Association may award the Executive bonuses in such amounts and at such times as the Association's Review Committee, in his or her sole discretion, deems appropriate. This process is documented. Compensation for the CFO and Associate Executive Directors was determined by the Chief Executive Officer. The CEO's basis for determining compensation is based on market data including the Association's Forum of Chicagoland.</ExplanationTxt>
