Governance Explanations

Form 990, Part VI, Section A, Line 6

For governance purposes, nuclear matters has one member: nuclear energy institute (nei).

Form 990, Part VI, Section A, Line 7A

Nei, as the sole member of nuclear matters, appoints the directors to the nuclear matters board of directors (i.e., the governing body).

Form 990, Part VI, Section A, Line 7B

Nei, the sole member, has the right to appoint directors to the board of directors and the officers of nuclear matters, the right to approve the annual budget, and other rights provided to members under d.c. Nonprofit corporation act.

Form 990, Part VI, Section B, Line 11B

The full board will receive a copy and will be given reasonable time to review and ask questions before the return is filed.

Form 990, Part VI, Section B, Line 12C

Nei employees shall identify any areas in which a possible conflict of interest might exist and contemporaneously disclose any situation that is, or might have the potential to become, a conflict of interest or that might appear to others to represent a conflict of interest. Failure to make such disclosures or making any false or intentionally misleading statements related to conflict or potential conflict may result in disciplinary action up to and including termination. Employees are required to sign a conflict of interest report annually to confirm that they understand the policy and that they have disclosed any conflict of interest or appearance of conflict of interest. As a general matter, supervisors should ensure that employees do not take part in any decision (e.g., the establishment of specifications; the evaluation and selection of products, services or equipment; the awarding of contracts; or the approval of payment for goods or services provided) that might create a conflict of interest. If an employee believes that he or she is or may become involved in a situation in which a conflict of interest exists or may appear to exist, the employee should promptly report it to his or her immediate supervisor.

Form 990, Part VI, Section B, Line 15

Salaries for all nei positions are benchmarked against industry standards, using mid-to-large-sized not-for-profit organizations as key comparators. All officer positions are evaluated against a compensation scoring system that ensures the salary range for the position is set relative to the position's internal and external responsibilities. Ceo and officer positions are also benchmarked against industry standards annually using the same comparator group as the other positions. The review is performed by an external consultant who provides recommendations to the organization & compensation committee of the nei executive committee. Those recommendations, if approved by the organization & compensation committee, are then provided to the executive committee for the executive committee's final approval.

Form 990, Part VI, Section C, Line 19

Nuclear matters did not have a request for documents during the year. Nuclear matters will make the documents available upon request for the period as set forth in irc section 6104(d).
