Automatic Contribution Arrangement expiration

[Guest Jones01]

Hello. I have found in the final regs (http://www.gpo.gov/fdsys/pkg/FR-2009-02-24/pdf/E9-3716.pdf), that the QACA provision provides for a plan to set an expiration date on the affirmative election.

I have not found in the final regs anything concerning allowing for a plan to set an expiration date on the affitmative election for an EACA, or the more general ACA.

I have referenced the IRS FAQs on the topic (http://www.irs.gov/Retirement-Plans/FAQs---Auto-Enrollment---Can-an-employee's-election-not-to-participate-in-the-retirement-plan's-automatic-contribution-arrangement-expire%3F), but the response is broad and unclear.

Is there an authoritative source someone can direct me to that can confirm if EACA/ACA allow for an affirmative election expiration?

Thank you
