that would be Blue Shield of California. As a"non-profit" their profit and administrative expenses are strictly limited - to 17% administrative and 3% profit. They studiously manage to get to that 20% each and every year. Except for the years that they went over and where forced to give a little bit back. For context, I think the Canadian single payer system operates on something like 4% overhead, and even Medicare, including and estimated 8% fraud, is around 10% (2% administrative overhead). It takes a lot of big executive salaries these days to run a large "non-profit", lots of expensive off-site conferences that just happen to be in resort areas, that sort of thing.
