Merrill+ is a separate program (which had been shared with a version of the deferred debit card). Accolades earns Worldpoints. Individuals who have both cards can transfers points from Accolades to Merrill+, but (to my knowledge), not the reverse. There has not been an application link for Merrill+ for a few years, but it may be possible to apply by phone or through a Merrill advisor.

This card was administered for Merrill by Bank of America even before they owned the company. If you review this thread (and others) you will see that Merrill tinkered with this card's benefits most years. Many are offered on a calendar year basis, but typically they do not publish changes until after the year has started.
