The Equal Employment Opportunity Commission ("EEOC" or "Commission") is issuing this final rule to amend its Age Discrimination in Employment Act ("ADEA" or "Act") regulations concerning disparate-impact claims and the reasonable factors other than age defense ("RFOA"). The Commission published proposed rules in the Federal Register on March 31, 2008, and February 18, 2010, for sixty-day notice-and-comment periods. After consideration of the public comments, the Commission has revised portions of the proposed rules and is now issuing a final rule covering both proposals.
