Interest calculation for decrease in TRM contracts - Loans (Int. rate instrument)

[former_member957466]

Hello everyone!

We have a process from our client that we are not able to recreate right now in TRM. Follow the example:

Loans contract of 1.000.000 USD - Begin 01.jan.2019 - End in 31.dec.2019 - Interests will be paid in the end of the contract (3%).

+ 1.000.000 USD --> 01.jan.2019 (principal)

- 1.000.000 USD --> 31.dec.2019 (pay principal)

- 300.000 USD --> 31.1dec.2019 (pay interests).

During the life of the contract, the client make a payment (decrease), and would like to pay the interests for this decrease in the same day.

+ 10M USD --> 01.jan.2019 (principal)

- 3M USD --> 01.feb.2019 (decrease)

- 7.75k USD --> 01.feb.2019

- 7M USD --> 31.dec.2019 (pay principal)

- 299.225K USD --> 31.dec.2019 (pay interests).

Or, he would like to pay the interest (01.feb.2019) based in the amount that he decreased from the contract, and not based in the total amount of the contract.

Where I can change this base amount to the calculation of the interest? I just got the scenario below:

+ 10M USD --> 01.jan.2019 (principal)

- 3M USD --> 01.feb.2019 (decrease)

- 25.833k USD --> 01.feb.2019 --> based on 10M usd --> 10M * 3% /360 * 31 = 25,833.33

- 7M USD --> 31.dec.2019 (pay principal)

- 641.666K USD --> 31.dec.2019 (pay interests).

Please, can someone help me?

Regards,

Bruno
