And our quarterly reports on form 10 Q. In particular, the extent to which the covid 19 pandemic can continues to impact our business is uncertain and depends on numerous evolving factors which are difficult to predict, including the duration and scope of the pandemic and of actions taken in response to it. Some of the financial measures discussed during this call are non GAAP financial measures. reconciliations of these measures are the closest gap measures are included in the appendix of this presentation and the earnings release.
