This excerpt taken from the ABII 8-K filed Nov 8, 2007.
We expect to adopt a defined contribution plan intended to qualify as an eligible cash or deferred arrangement under Section 401(k) of the Internal Revenue Code. Under the 401(k) plan, participants will be able to defer a percentage of their compensation, the dollar amount of which may not exceed the limit as governed by applicable law. The 401(k) plan will also permit discretionary matching contributions by us in amounts and subject to limitations specified by our board of directors. Individual participants will be entitled to direct the trustee to invest their accounts in authorized investment alternatives selected by us.
