There is not a specific report that can be run in the reporting module but this can be done.
Go into File Maintenance Matter Manager.
Right-click where you see data, left-click Select Grid Fields, and drag Fee Arrangement to where the column headers are.

Click Refresh.
Now you can sort on this column by clicking on the Fee Arrangement column header, or you can select the down arrow on the header and that will only show whatever fee arrangement you have selected.

Once you have set the criteria you can go to Report and print out the results.
