For particular types of expenditure which may be incurred under this heading (but which may also qualify under other parts of OTA75\S3(1)),


  • OT09275, material stocks
  • OT09300, redundancy
  • OT09325, overheads
  • OT09350, insurance
  • OT09600, sale and leaseback (where, in particular, expenditure is subject to specific limitations).
