"as soon as it was reasonably determined the item was lost"
I'd agree with that too - it should take no more than a week or so to file a claim and have the shipping company admit that it is lost and start a search. In the case I described, I was able to have fedex redirect the package to a new address after it was found (over a month and many phone later) so the ability to redirect the lost package (at least at fedex) should provide protection for the seller and allow for a much quicker refund to the buyer.
