long-term stale statement?

I understood that a stock usually only has a stale statement flag for a few weeks, but BPRN had a stale statement flag from early February 2018 all the way to November 2018. This is very unusual, right? Is there an explanation for this? Nine months for a stale statement seems odd.

Not sure how it’ll help you, but the following screenshot shows off some of my research on date functions. These formulas are applied to BPRN. The formula names should give an idea of the intent. Let me know if otherwise.

The gist is that it may be possible to piece together some of the vagaries we have been given into a coherent picture.
