Asura did not voluntarily revoke its registration, they were seriously delinquent on its filing requirements. It caught notice of Division of Enforcement at the SEC where they sent a certified letter of notice to cure the delinquency.
The Company then responded. The Company has an opportunity to "withdraw" its registration by filing Form 15-12g with the SEC on Edgar, subject to the company having the provisions available to them. In this case, they did not "voluntarily" file a "withdraw" because it had too many shareholders and did not qualify to withdraw its registration because it is not exempt from its filing requirements.
Without having the ability to voluntarily "withdraw" its registration, it was left with one of two choices: 1) ignore the OIP initiated by the Commission; or, 2) respond to the notice.
Either way, the Commission was going to proceed with the OIP to revoke the registration of the company's securities pursuant to Section 12j of the Act with or without the consent of the issuer.
In this case, the issuer agreed to the Commission revoking its registration, not that it had any choice.
