To record a cancellation in Pulley, first select the security that needs to be cancelled. (For example, Cap Table > Shares > CS-6).
Click the Actions dropdown, then click Cancel.
Fill in the Cancellation Date and Cancellation Reason. Click Next.
Review the cancelation details for accuracy and then select Cancel Security. The shares from the canceled security will return to the pool.
Once you've completed this process, the security will be marked as cancelled, and a record of the cancellation will appear in the security's Activity Timeline.
