In stage 2, Abt solicited SSDI-only participants from the solicitation pool created
                  from the original list. If the beneficiary consented to be a part of the project,
                  Abt randomly assigned the beneficiary to one of three groups: (1) a treatment group,
                  which receives the $1 for $2 offset; (2) a treatment group which receives the $1 for
                  $2 offset with enhanced work incentives counseling; or (3) a control group which is
                  subject to existing non-BOND rules. Enrollment for stage 2 ended in September 2012.
               
               Individuals who completed the enrollment process received a $40.00 incentive payment
                  in appreciation for their time. We will pay other incentive payments after completion
                  of the 12-month survey ($25.00) and the 36-month survey ($45.00).
