The Millions New York Counties Coulda Got

In 1999, New York counties had a choice to make. They had just been promised annual payments from tobacco companies as part of a national settlement to reimburse them for smoking-related health care costs. Like winning the lottery, they could either get small payments indefinitely -- or take a lump sum immediately by entering into "securitization" deals. Counties knew that these deals would mean less money in the long run, but bankers said they offered protection in case the payments shrank or went away. Now the cost is clear: millions pledged to investors that counties could have kept for themselves.
