As you are aware, last year the Cross-Community Working Group on Enhancing ICANN Accountability's Work Stream 1 Report recommended that the key parts of the Affirmation of Commitments be brought into the ICANN Bylaws, and that the Affirmation itself be terminated.
As of 1 October 2016, the Affirmation reviews are incorporated into ICANN's Bylaws, as well as an annual reporting requirement on those reviews. ICANN's obligation to support broad, informed participation is now part of ICANN's Core Values; the obligation to produce rationales for ICANN decisions is part of ICANN's Bylaws-mandated commitment to transparency. ICANN's commitment to remain a not-for-profit corporation, headquartered in the United States of America is embedded into ICANN's Articles of Incorporation, and in the Bylaws, which specify that ICANN's California office is its principal place of business.
This week, ICANN and NTIA have finalized the formal termination of the Affirmation of Commitments here [PDF, 252 KB].
