From NYT:

The proposal is the result of more than a year of preparation and more than three months of intense negotiations between a small group of Democrats and Republicans led by Senator Max Baucus, Democrat of Montana, the chairman of the Finance Committee.
The first surprise in the Baucus plan: a slimmed down price-tag of $856 billion over 10 years. Earlier versions of the health care legislation had come in costing $1 trillion or more. But stay tuned for a close look at the fine print; Congressional budget-scoring is often as much art as science.
Another number to watch: 13 percent. That’s the share of family income that the Baucus plan envisions middle-class American families having to pay in health insurance premiums before co-payments, deductibles and other cost-sharing.
