Unless they specifically state that all pay is being deferred, we can safely assume it is merely a part of their rather generous salary that they have "deferred", and not all of it.
One might also point out that their jobs are not, as far as I know, full time. Heddle still lives in Florida, I believe, tending to his business there. Probably Bordy isn't dedicating himself exclusively to PTOI either, given that there are no longer any normal operations.
