Quick answer: 36 million went to the government. 61 million didn't exist: the 183 million would have been paid out over 30 years, during which time (in theory) the 112 million would be making investment interest, plus the dollar value would be shrinking, so the payouts would be worth less then paid out 10, 20, up to 30 years later. Now, a person with half a brain and reasonable risk aversion should be able to take 76 million and grow it to more than 183 million over 30 years, so it would be better to take the upfront money and run it yourself, either for your own betterment or to grow a charitable foundation.
I agree with you. I just thought it was funny that they mention the after tax haul without mentioning the already imposed tax of $71 million for taking the cash payout.
