INFORMATION GATHERING Our self-evaluation process is conducted on an anonymous basis, using our Board portal. We have found by using an anonymous evaluation process, the Board and committee members have a level of comfort in being able to critique the Board and/or the committees.

ANNUAL BOARD AND COMMITTEE EVALUATIONS The Board and each committee conduct annual self-evaluations through the use of electronic questionnaires in the Board portal that cover the topics discussed on the previous page.

SUMMARY OF EVALUATIONS Hecla’s Secretary uses our Board portal to generate a summarized report of our directors’ anonymous responses to the electronic questionnaires and submits the report to the appropriate chair of each committee of the Board for review before the next quarterly Board and/or committee meeting.

BOARD AND COMMITTEE REVIEW Using the summaries of the self-evaluations as guides, our chair of the Governance Committee reviews the results of the Board evaluation, and each committee chair reviews the results of each committee evaluation. The self-evaluations and summaries are shared and discussed with the full Board and each committee.

These enhancements reflect the Board’s commitment to continuous improvement in governance practices and its recognition that individual accountability and peer perspective are important complements to group self-assessment.
