Usually layoffs have a one-time charge associated with closures and severance and other such payments (COBRA?).

But $230 million over 1,600 is $145k per person.

I’d guess some of that is accounting for taxes on profit they’ll now have to pay that otherwise would have been deductible if spent on salaries for R&D?

Block reportedly handed out a bunch of incentives to the people staying, could be similar to that.
