How Retro Works


PITB is an association who sponsors three state-approved retro groups administered by Approach Management Services. Members report worker hours in similar risk classes and must be approved to join the group.

Work Together

The retro group’s premium is pooled together to cover the cost of the claim losses.  Each member commits to robust safety practices and proactive claims management.  Members work closely with a professional workers’ compensation analyst to help injured workers get back-to-work and mitigate costs.

Earn Refunds

Each year the groups premium is compared to losses and if the premium exceeds the losses the group is eligible for a refund.  Since 1981, the Retro program has refunded billions of dollars back to participants.
