BF#C F# Cash Position Upate

Introuction

The BFXC, FX Cash Position Update batch task is used to update the

foreign exchange trader currency pair position using all debit/credit

amounts for the foreign exchange cash general ledger account created

from journal entries or accounting tasks that do not directly update

trader position.

The BFXC, FX Cash Position Update task is run in the nightly batch

Moifications

BFXC will be modified to include a new text box that will allow the

user to specify a currency with which BFXC will disaggregate the cash

position.

When a currency is entered, BFXC will do the following

Use existing logic to calculate the foreign currency against

base currency position.

Retrieve the Spot Revaluation Rates from the REVP table

Calculate the rate for each currency against that specified on

the BFXC disaggregate currency field using the spot

revaluation rates.

Calculate the disaggregate amounts and create the position

updates for each disaggregate currency pair using thecorresponding Cash Position trader, portfolio and cost center

on the CCYP table.

Normally, when the checkbox Use Implied Spot Rate from ACUPs

is checked then BFXC calculates the conversion rate to use from the

currency amount against the base equivalent. In this example, BFXC

would produce the following CPPR update

PORT1 1000 3 Jul 2001 347,367.11 -125,000 2.77893688

However, the user has specified a disaggregate currency of USD.

Instead of posting just the AUD/GBP position as above BFXC will

now calculate and post a AUD/USD, CPPR.CCY1 against

disaggregation currency, and a GBP/USD position, CPPR.CCY2

against disaggregation

The AUD/USD (CCY1 against Disaggregation currency) rate is

calculated using the spot revaluation rates from the REVP table.

AUD/USD rate = 0.5080

The GBP/USD (CCY2 against Disaggregation currency) rate is

calculated using the AUD/USD and AUD/GBP rates, so

GBP/USD rate = GBP/AUD x AUD/USD

= 2.77893688 x 0.5080 = 1.41169993504

BFXC will always use the REVP rate to calculate the base currency

against the disaggregation currency whether the base is CCY1 orCCY2. BFXC will then use that rate in conjunction with the rate used

for the foreign currency against base currency to calculate the foreign

currency against disaggregation currency rate.

GBP USD TRAD2 PORT2 1000 3 Jul 2001 -125,000.00 176,462.49 1.41169993504

The trader, portfolio and cost center that BFXC posts to are those from

the CCYP of the disaggregate currency pair not the currency against

base pair.

When the checkbox Use Implied Spot Rate from ACUPs is not

checked then BFXC uses the REVP spot rate for the currency against

base, this will not change. However, BFXC will now use that rate to

calculate the rate for the base against disaggregate currency.
