The best would be a business that purchases his things for him.
E.g. he starts an LLC, profits stay in the company, company provides meals, vehicle, and phone+plan for the execs, plus travel expenses, and he gets a low salary from which I guess he still has to pay his rent.
Can't the LLC rent some flat as "company apartment" for "employees traveling on business", that happens to be in the same town as the HQ, and, since the LLC has only one employee...
Or just plain rent it and sublet it to the CEO for peanuts.
(This is all fun speculation, but Nintendo lawyers aren't idiots - the actual settlement likely covers LLCs, startups, benefits, and all other obvious workarounds. Hell, it probably makes Nintendo entitled to the 30% of unreported cash income and proceeds from crime as well.)
I assumed it was an order imposed by a judge and that there was some kind of standard process here. It's not abnormal for a judge to order you to pay X% of your salary capped at Y dollars a month, for example in child support.
It's unclear from the article what the nature of the payment is. It's described as a "fine" rather than "damages" but also mentions an "agreement with Nintendo".
