He talked about the IRS §382 rule. They were limited to a maximum of $100 million stock repurchase (until Aug. 2021, then they can buy back much more). In the last erarnings call they reported they already bought back 1.2 million shares for ~$23.3 million, so there were ~$76.7 million left at that point in time. We do not know if they bought back more shares up to now, but I am sure they will tell us at the next earnings call.
As they said, if the stock is still at these levels in August 2021, they will buy back shares "in a far more aggressive way"...
