One event may result in more than one affirmative answer to Items 11.C., 11.D., 11.E., 11.F. or 11.G. Use only one DRP to report details related to the
same event. If an event gives rise to actions by more than one regulator, provide details for each action on a separate DRP.

adviser's or advisory affiliate's favor.

If you are registered or registering with a state securities authority , you may remove a DRP for an event you reported only in response to Item
11.D(4), and only if that event occurred more than ten years ago. If you are registered or registering with the SEC, you may remove a DRP for any
event listed in Item 11 that occurred more than ten years ago.
This DRP should be removed from the ADV record because it was filed in error, such as due to a clerical or data-entry mistake. Explain the
