        <ExplanationTxt>The audited financial statements report revenue in 2020 as well as the only prior-year revenue adjustment, while Form 990, Part I reports only revenue in 2020. The difference is the only prior-year revenue adjustment in the amount of -$5,513 and therefore reported on this line. It represents a refund of a portion of a grant to the non-government organization that had awarded the grant in a prior year. The refund was made because that portion had still been unobligated by the end of the period of performance of the grant in 2020. The prior-year revenue adjustment is also reported on Form 990, Part XI, Line 9 and explained on Schedule O (Form 990).</ExplanationTxt>

Paid leave earned in 2020, but not taken in 2020, could be considered deferred compensation and therefore be included, but the organization maintains a bona fide paid leave plan and as such paid leave earned in 2020, but not taken in 2020, is not considered deferred compensation and therefore not included. The nontaxable benefits reported in Column (D) are comprised of the employer and employee contributions to the health, dental, and vision insurance premiums, payments into the medical and dependent daycare flexible spending accounts, which are entirely made by the employee, and payments of the workers' compensation insurance premiums, which are entirely made by the employer. The forgoing describes all benefits whose amounts are included in Columns (C) and (D). Of all those benefits that are not required, but can be elected, not all were elected by the employee, Edward V Denison.</ExplanationTxt>

        <ExplanationTxt>The governing body, i.e., the board of directors, held a special meeting in December 2019 to deliberate on an appropriate compensation of the organization's CEO for 2020. The one director who is also the organization's CEO recused himself from the deliberation. The other directors, in their deliberations, selected another organization with a comparable mission and a position at that other organization that they consider comparable to the position of the organization's CEO. They then determined from the pay scale for that position at the other organization, which lists compensations based on years of experience, the appropriate compensation of the organization's CEO for 2020. The secretary of the organization was present at the special meeting and recorded minutes of it. The minutes were subsequently approved by the board of directors.</ExplanationTxt>

        <ExplanationTxt>1) The organization is in the following referred to as the employer. The compensation reported in Column (F) is comprised of employer and employee contributions to the health, dental, and vision insurance premiums, payments into the medical and dependent daycare flexible spending accounts, which are entirely made by the employee, employer contributions to the 403(b) retirement plan, and payments of the workers' compensation insurance premiums, which are entirely made by the employer. Paid leave earned in 2020, but not taken in 2020, could be considered deferred compensation and therefore be included, but the organization maintains a bona fide paid leave plan and as such paid leave earned in 2020, but not taken in 2020, is not considered deferred compensation and therefore not included. Of all those benefits that are not required, but can be elected, not all were elected by all employees. 2) The organization has chosen not to apply the $10,000-per-item exception to any item. 3) The compensation of Dr Jurgen Theiss, Director, President, and CEO, given by the sum of the amounts reported in Columns (D) and (F) is not identical to the expense reported on Form 990, Part IX, Line 5, Column (A). The difference exists because the compensation includes, but the expense does not include, the portion of the paid leave that he earned prior to 2020 and took in 2020, which is in the amount of $7,286, and the expense includes, but the compensation does not include, the portion of the paid leave that he earned in 2020 but did not take in 2020, which is in the amount of $10,905.21. The difference is therefore $10,905 - $7,286 = $3,619.</ExplanationTxt>
