Interim resolution professional costs must be fixed by the applicant; adjudicator fixes if not, and ratified costs are reimbursable. The applicant must fix expenses for the interim resolution professional; if it does not, the adjudicating authority will fix them. The applicant initially bears the expenses, which the committee of creditors may reimburse to the extent it ratifies; amounts ratified by the committee are treated as fast track process costs. 'Expenses' include the interim resolution professional's fee and other costs, including fees for professional advisors.
