The claimant sought entitlement to the cost of an accounting report and interest on IRBs. The insurer had paid IRBs at a lower rate and then increased the weekly IRB payment upon receipt of further information. Adjudicator Ferguson held that the insurer was not required to pay for the accounting report because the claimant was an employed individual and the IRB calculation was very simple. It was not reasonable to retain an accountant. In terms of interest, Adjudicator Ferguson ordered the insurer to pay interest on the increased IRBs even though the claimant was late in submitting documents.
