Subject: Re: Buyback average price
So, one might infer that management currently feels that they would be happy buying B shares at about 623,205.69/1540 = $404.70 per B.

FWIW, that's 1.56 times end year book, the last publicly known level. A bit eyebrow raising, in a way.
For the longest time the highest known-for-sure single buyback was at 1.438 times then-known book.

It's a "mere" 1.527 times Q1 book, i.e. book at end of the month (March) of the purchases.
