IDC mentioned that running at (too) high gross margins might obligate the FTC to step in especially since Intel is looking like it might be the only player in town within the next very few years. So its one of the reasons Intel has to pump extra money to essentially compete against itself and keep cranking out ever better faster chips at a goodly pace.
So I was just thinking if Intel could actually slow the pace of innovation without perturbing the FTC.
I see your point now. The short answer is no, never. The long answer goes below.
For them to do that they would have to incur in expenses that didn't happen, so they would have to forge an expense, the receipt and move the money elsewhere. The problem is that they would have to put the money completely out of their subsidiaries, as they have to consolidate those in the financial statements in the SEC fillings. I don't think any sane management would do that, as they would not be defrauding the IRS or the SEC, but also the shareholders. It's the kind of gargantuan screw-up that they don't want to bring over Intel, something at the levels of Enron or Worldcom.
There is another alternative, bring some items that would be deemed investments as costs, which would erode their current results but not he future ones, but there is a limit on how far you can go with this. The further you go, the further you are likely to breach some cardinal FASB rule.
I see that you worry a lot with Intel gross margins, but the FTC doesn't. The FTC won't bother with Intel margins, they are likely to bother with consumer prices. If Intel platform costs keep rising from generation to generation then the FTC is likely to step in to rein Intel, but if prices are more or less stable, or slowly decreasing, even if margins were going up a bit, then no.
Intel margins aren't likely to go up too much if AMD retires from the market. The only area where Intel faces competition is in the bottom market and there it is Intel who dictates prices, not AMD, so they are already very comfortable with prices and margins. To move prices up would mean impact volumes, something they really don't want to do in the medium term.
Intel margins are likely to influence the resolve of any would-be competitor to pick a fight with Intel. One thing is to buy an AMD with 35% gross margins and Intel with 60%. But let's say that Intel reaches 70% gross margins, it is highly unlikely that a company a bit less incompetent than AMD could not field products that generated around 45% gross margins and make money. So while Intel must generate enough cash to make shareholders happy and keep them ahead of the other players, they must calibrate their prices in order to not attract undesirable competition.
Keep in mind that manufacturing is a fundamental stone in Intel strategy, much like having the best x86 design on the market. It is the best design making use of the best fabs available that makes Intel chips what they are. I don't see Intel slowing down even if they were alone, much less with ARM around the corner.
