The issue is rate of return. They are evidently spending $4.85bn on Xbox per year. The US federal interest rate is 3.5% so if you just put that money in US bonds you would get about $175M per year of much purer simpler gravy.

Russ: "Anyway, next thing you know, we IPO, stock triples in a day and AOL gobbles us up. All of a sudden, I'm 22 years young and I'm worth 1.2 billion. Now a couple decades later, I'm worth 1.4. You do the math."

Richard: "Okay. Well, that's a gain of $200 million over 20 years. Um, 16.66 repeating. That's less than 1% return. Inflation is, like, 1.7. I think CDs are 2%. So that's less than a CD."

But the revenue is coming out of the same org. That $5bn revenue only exists because of the $4.85bn expense. That money doesn't exist to put into bonds unless it's coming out of the games org. They can only make their margin percent look better by making their absolute margin $150mm worse.

Exactly. The inflation rate is about 3%, so the people at Xbox worked very hard all year to have about the same value they put into it.
