A 2013 requirement to provide a notice to employees has been updated. The notice must include the following:

(1)
informing the employee of the existence of an Exchange, including a
description of the services provided by such Exchange, and the manner in
which the employee may contact the Exchange to request assistance;

(2)
if the employer plan’s share of the total allowed costs of benefits
provided under the plan is less than 60 percent of such costs, that the
employee may be eligible for a premium tax credit under section 36B of
title 26 and a cost sharing reduction under section 18071 of title 42 if
the employee purchases a qualified health plan through the Exchange;
and

(3) if the employee purchases a
qualified health plan through the Exchange, the employee may lose the
employer contribution (if any) to any health benefits plan offered by
the employer and that all or a portion of such contribution may be
excludable from income for Federal income tax purposes.

Expect a updated finalized version  this summer or
fall.  At that point a new mandatory date will be provided.
