Thanks for that awesome link. To clarify, and to answer
@Marius L 's points:
The casinos don't profit on any chip that they might have to redeem, but they do profit on any chip that they will
never have to redeem. The difficulty is knowing what proportion of their outstanding chips won't ever have to be redeemed. They do know that
some won't; these are considered "souvenirs and lost chips" i.e. chips that patrons decide to take home with them, and chips that patrons have mislaid somehow, never to be recovered by anyone. They know that every souvenir and lost chip represents income; this goes straight to the bottom line, making the casino more profitable. They have to account for this income from souvenirs and lost chips in their financial statements to investors, and they have to account for this income in their tax filings.
The two ways that they can try to account for souvenirs and lost chips are:
- Wait for the chips to be retired. Any that aren't presented by the end of the final redemption period will never have to be redeemed, and so they all count as income at that time.
OR
- Estimate on a periodic basis (e.g. annually) how many of the currently outstanding chips are going to never be redeemed, by counting how many get redeemed within a short period (e.g. a week or two) at the time of the date of estimation.
So, yes, absolutely, when you buy a rack of fives from the cage and bring them home and put them in your cabinet, the casino does indeed profit from that. They have to account for that profit to their investors and to the IRS, and they do so by either counting it
eventually when the chips get retired, or more commonly by
annually estimating the number of chips that have been squirreled away that year.
And if you do it with a rack of ones, then in the exact same manner the casino gets $100 of income, but will also incur an operating expense (netting out to a small loss of probably around 25c per chip) if and when they decide they need to replace the chips that walked away with more chips from the same non-retired series.
