Additionally,  budget  submission  requirements  provide for reporting obligations by material categories, and fund codes have been assigned to these categories. DEFENSE FINANCE AND ACCOUNTING  SYSTEM The   Defense   Finance   and   Accounting   System (DFAS)  performs  the  official  accounting  and  reporting for   operating   budgets   granted   for   operation   and maintenance  of  ships  and  ship  commands.  Also  for administrative  expenses  of  staff  and  headquarters commands.  Atlantic  Fleet  ships  and  commands  report obligation data to DFAS, Norfolk, and Pacific Fleet ships and commands report to DFAS, San Diego. Each DFAS  maintains  records  of  each  ship’s  obligations.  As requisitioned  material  is  supplied  and  vouchers  paid, they  match  them  with  the  expenditure  documents received  from  supply  activities  and  disbursing  offices. The listings resulting from this matching process is reported to the ship monthly. This enables the OPTAR recordskeeper  to  make  corrections  to  the  appropriate records and report any errors to the DFAS. OPTAR ACCOUNTING As has been previously stated, the commanding officer is responsible for the effective and economical use   of   OPTAR   funds   and   for   making   sure   the obligational  authority  is  not  exceeded.  The  supply officer  is  responsible  for  maintaining  required  records and  submitting  status  and  transactions  reports  to  the commanding officer, type commander, and DFAS. In discharging this responsibility, the supply officer relies on   the   OPTAR   recordskeeper   to   maintain   the Requisition/ OPTAR Log (NAVCOMPT Form 2155), prepare  reports,  and  informs  the  supply  officer  of  any unusual    transactions. You,   as   the   OPTAR recordskeeper,  must  assume  a  degree  of  responsibility for the proper use of funds. This is because you will be posting  all  transactions  to  accounting  records  and  can review them for accurate fund codes and completeness. FUND CODES Fund  codes  are  established  by  the  Comptroller  of the Navy and assigned to the various type commanders. Of  the  fund  codes  assigned,  the  type  commanders designate those that may be cited by afloat units. The OPTAR grant may be allocated to these fund codes. Since fund codes are the primary source of accounting data, it is essential that they be assigned correctly. If the stock record cards have been annotated to indicate “equipage, repair parts, and consumables” the stock records Storekeeper will be able to verify fund codes during  the  process  of  posting  the  NAVSUP  Form 1250-1. This occurs before they are passed to you for posting  to  the  accounting  records.  All  fund  codes currently assigned are listed in NAVSO P-3013-2. REQUISITION/OPERATING TARGET LOG Each   ship   and   command   must   establish   a Requisition/OPTAR  Log,  NAVCOMPT  Form  2155,  in which  all  documents  are  recorded.  The  log  is  the principal   shipboard   financial   control   device.   The Storekeeper who maintains it and its supporting files is known  as  the  OPTAR  recordskeeper.  Most  of  the columns  in  the  OPTAR  Log  are  self-explanatory. However,   the   following   general   rules   should   be observed: All entries should be legible, and in ink. The  ship’s  name  and  hull  number  should  be written  in  the  space  provided  in  the  upper right-hand comer of each page. Each page should be numbered in sequence. The fiscal year should be entered on each page (fiscal year OPTAR granted). As   the   OPTAR   recordskeeper,   you   have   the responsibility of maintaining the OPTAR logs for your ship. For the first 6 months of any fiscal year, you must maintain two separate logs at the same time. One is for the  current  year  and  the  other  for  the  immediate preceding year. After Match, the DAO will take over OPTAR accounting and reporting for the remainder of the 36-monthlife cycle of the appropriation. Details for accounting and reporting procedures for the current and subsequent years for O&MN funds are promulgated in Financial  Management  of  Resources  (Operating Forces},   NAVSO   P-3013-2   and   Afloat  OPTAR Recordskeeper’s Guide, NAVSO P-3073. The  OPTAR  amount  established  by  the  type commander  must  be  entered  on  the  Requisition/OPTAR Log. This amount is then reduced by the value of each chargeable  transactions. Not  all  transactions  are chargeable   to   the   OPTAR.   Requisitions   citing nonchargeable fund codes are recorded in the log for the purpose of maintaining requisition number control, although they will not have an effect on the OPTAR balance. Some nonchargeable requisitions may have to be completed as chargeable at a later date. Various 10-2
