Accounting structure
Chart of Account structure
For OCBC SIN, this is the chart of account (COA) structure. It consists of 19 digits. Murex has a constrained of maximum 20
digits.

Entity code (3-digits) – retrieved from the Portfolio user-defined field (UDF).

Cost centre (3-digits) - retrieved from the Portfolio UDF

GL account code (5-digits) – retrieved from accounting mapping table

Product code (3-digits) – retrieved from typology or product mapping table

Customer segment code (2-digits) – retrieved from counterparty or portfolio mapping

Sub-ledger code (3-digits) – country specific logic
For OCBC NISP, the structure is proposed to be a bit different. OCBC NISP is looking for a GL account code that is 8 digits. In
order to accommodate this setup, this is the configuration that is under consideration:





Entity code (3-digits) – retrieved from the Portfolio user-defined field (UDF).
Cost centre (3-digits) - retrieved from the Portfolio UDF
GL account code (8-digits) – retrieved from accounting mapping table
Product code (3-digits) – retrieved from typology or product mapping table
Customer segment code (2-digits) – retrieved from counterparty or portfolio mapping
Organisation of the GL code presentation
In OCBC NISP, the 1st digit specifies financial classification:

1 – Asset

2 – Liability

3 – Equity




4 – Revenue
5 – Expense
6 - Commitment & Contingent
7 – Contra Commitment & Contingent

Accounting FX treatment
Accounting currency is setup in the entity level.
All currency that is not accounting currency is considered as Foreign Currency.
FX conversion is done for foreign currency to a specific currency based on configuration. The exchange rate is taken from
the accounting fixing rate.
Day 2
Accounting processes
Accounting simulation
Accounting simulation is an important tool to verify whether the accounting rules setup is performed correctly or not.
After trade query, go to Tools -> Building accounting entries and Click 'Yes' to proceed.
This is a function that allows user to know what entries would be generated during the accounting EOD.

Accounting Marked-to-Market
Sample trade: 13439237 (FXD)
Computation:
(MV + FCP + PV) * Accounting fixing rate
= (-4873.54481239972 + 0 + 0.000751812806811358) * 1.68261386862429
= -8200.29
Sample Trade: 13646878
Computation:
(MV + FCP + PV) * Accounting fixing rate
= (29.6754500007038 + 0 + -0.00163336417994486) * 1.24686050005053
= 36.99911
Sample trade: 13650865 (Option)
Refer to murex document:
5.1.1311
Marked to Market Revaluation Formulae
Computation:
Market Value (Discounted) + Cash future initial payment flat (Discounted) + Cash past initial payment flat (Non Discounted)
= MVDisc+CshFutIPCapDisc+CshPastIPCapNonDisc
= (-11793.8760544467+ 0 + 64800)
= 53006.1239455533
Accounting Interest Accrual
Refer to murex document:
5.1.26
Accounting accruals calculation
Calculation of interest accrual is related to a configuration in the Accounting Template.
End of Month booking
EOM Amount: amount of the last accrual entry of the month is equal to the exact value of accrual at the end of the month.
Non working day booking
This flag is used to manage the end-of-week interest.
Actual amount: amount of the accrual entry is equal to the exact value of accrual at this date
Sample trade: 13652145 (Loan & Deposit)
Interest accrual entry is generated daily and reversed out the following day.
The interest accrual amount can be obtained from the P&L (Accounting breakdown) function.
Sample trade: 13557395 (Bond Live)
There is a distinction for bonds traded under the AFS book. The premium/discount is recognized outside of the FI asset
account. It is amortized daily until bond maturity or bond is netted.
The interest accrual and the premium/discount amortization can be obtained from the P&L (Accounting breakdown) after
performing trade query.
Sample trade: 11774177 (Bond netted - partial)
Computation of the amount of premium/discount that is offset due to netting:
= Original premium-discount * (netted quantity / original quantity)
= 517500 * 20000/150000
= 69000
Computation of the realized amortized premium/discount:
= Effective yield amortization from P&L (accounting breakdown) * (netted quantity / original quantity)
= 38831.7037856325 * 20000/150000
= 5177.560504751
Note:
The netting is performed on 16 Aug 2013 so the P&L breakdown should be retrieved for 15 Aug 2013.
Sample trade: 13267095 (Bond netted - full)
In this sample, the sell leg is fully netted with another Buy deal (5313678). Therefore, the remaining position is left with
only the Buy leg.
Sample trade: 13263966 (Bond_Repo)
For Bond Repo, the interest accrual is found in the second leg of the P&L (Accounting breakdown). The first leg is the P&L
for the underlying instrument.

2 – Expiry
3 – Early Termination
4 – Netting
5 – Restructuring
6 – Cancel & Reissue
7 – Delete
Sample restructuring accounting
Sample trade: 10403773 (Option)
The restructuring happens after the premium in the original trade has settled.
Restructured trade: 11144654 (Option)
Though the premium is revised, the premium amount posted for restructured deal is still the original trade premium.
Sample cancel&reissue accounting
Sample trade: 1202990 (Option)
The cancel&reissue happens after the premium in the original trade has settled.
Cancel&reissue trade: 1416251 (Option)
The new trade posted the new premium amount in the cancel&reissue deal.
Day 3
Accounting EOD script
End of day job sequence
Accounting EOD is performed after FO or PC (need to confirm) move date is completed. Generally, it follows this sequence
but to be confirmed against Control-M setup:

End of day job script
Refer to murex document:
5.1.216
Accounting End of Day procedure


3-ACCOUNTNG EOD SG
2-ACC MOVE DATE SG
As part of the accounting EOD, there are four key steps to be performed:

ACCCOPY-FX: Copy the FX rates into the Accounting Fixing rates.
Accounting EOD

ACCEOD-TRN: Generate the accounting entries between accounting date (included) and target date (excluded).
In this sample, OCBC SIN splits the EOD day into LN_BR and non LN_BR. This is not required for NISP.

ACCEOD-BAL: Compute the accounting balances between target date and accounting date. When the shifter is
left empty, system will compute the balance for the accounting date only.

ACCEOD-MVDATE: Move the entities account dates to the target date. If the target date is earlier than the
current accounting date, it removes all accounting entries from the target date to the accounting date.
End of day troubleshooting
Troubleshooting - Accounting monitoring Monit
These are two processes that should be active when accounting EOD is running.
Troubleshooting - Accounting -> Audit -> End of Day audit trail
The end of day audit displays the product that is processed by the accounting end of day.
In a typical end of day process, the audit will display this information:

Start of accounting engine

Loading of accounting rule

Reading of transaction audit information

Generate the accounting entries
Most of the items in the audit trail come in pairs. For example, the LOAD RULE (code 1871671) will have a start entry and
an end entry. When the END entry is missing for a particular task, it means that task is still running or has failed.
If a step has been running for a long time, the audit table will shows the last step that the accounting end of day is
performing. From there, it will give an indication of where the processing is taking a long time and troubleshooting can
commence from the database or UNIX level.
Recovery
There will be situation where we need to undo an accounting end of day.

ACCUNDO-TRN: Remove accounting entries between target date (included) and accounting date (included). This
is different from undo move date as manual entries by users are not removed.

ACCEOD-MVDATE: Move the entities account dates to the target date. If the target date is earlier than the
current accounting date, it removes all accounting entries from the target date to the accounting date.

Accounting process capture a set of FX rate for the conversion to accounting currency.
This function is accessible through Accounting -> Query -> FX spot rates
This will be the FX rate that accounting EOD use to perform the FX conversion.
If the FX spot rate is not copied over during the End of Day process, the rate will all be zero.
Accounting Audit Table
Accounting audit table captures the event where accounting entries for a trade is to be reviewed.
This function is accessible by Accounting -> Audit -> Trade Audit Trail -> One audit entry
