" and are based on the facts and information made available as of the date of this report"
seems like a get-out-of-jail-free clause; albeit not unreasonable in our profession.
I've had the "facts" presented to me/available on scene change dramatically upon going to court.

On this point, I had a retail fire Friday where my client (Insurer) denied the other party's FI access to the site;
I strongly advised against this, since it means that each FI only has access to half the data
(the other party promptly denied me access to the witness of their staff etc.)
meaning we might head to court a few years down the line with (potentially-clashing) hypotheses based on incomplete data sets.

I realize FI's just generally want to get to the bottom of the fire cause
and loss adjusters must protect their Client's interests legally
(my pet theory is that the lawyers do it on purpose in order to book hours),
but ultimately, the Truth will out - preferably sooner than later...
