As I said in my remarks, we're certainly supportive of it being voluntary. It's a principle for us. The voluntary aspect is important to us, as any additional tax without individual benefit goes to increasing the cost of providing care. Frankly, it goes to making access more difficult rather than easier, as we see with the other benefits of this program.
At CDA we see it in the same way we see commercial insurance. Dentists purchase insurance for their practices all the time. None of the insurance is mandatory. It's based on personal situations, perceived future need, and so on. The only mandatory insurance is malpractice insurance, which of course is for the patient's protection.
