# Recalculate after a default

> What happens in the SLC cycle, and through Lerian, when a participant with a net debit does not pay in full.

Adjust the cycle when a participant with a net debit does not deposit the full amount, whether it is another participant or your own institution.

<Note>
  This flow is a suggested reading of the Núclea and BACEN manuals. The manuals prevail over this page. Your institution, as the participant, validates the flow and implements it on the Lerian APIs. See [how to read the diagrams](/en/diagrams/introduction).
</Note>

## Participants

***

* **Your institution.** The participant that runs the journey and books its effects.
* **Lerian.** Lerian SLC, Lerian SILOC and Lerian SPB. They exchange the messages with Núclea and STR, and expose the API and the events your institution uses.
* **Núclea.** Runs the SLC and SILOC clearinghouses and their settlement windows.
* **STR (BACEN).** The BACEN reserve transfer system. It moves the money between reserve accounts.

| # | From | To | Message | Lerian API | What happens |
| - | - | - | - | - | - |
| 1 | Núclea | Núclea | Internal step | | At the end of the deposit window, Núclea excludes the defaulter and recalculates the balances. |
| 2 | Núclea | Lerian | `LDL0021` | | Núclea sends a new request with the recalculated balance and a new deadline. |
| 3 | Lerian | Your institution | Lerian API | Event `clearing.cycle_recalculated` | Lerian publishes the recalculated cycle with the new amount and deadline. |
| 4 | Your institution | Lerian | Lerian API | Pending | If your institution is a debtor, command the new amount or the difference within the new deadline. |
| 5 | Lerian | STR (BACEN) | `LDL0022` | Pending | Lerian sends the deposit to STR. |
| 6 | STR (BACEN) | Lerian | `LDL0022R1` | Pending | STR returns the result of the entry. |
| 7 | Núclea | STR (BACEN) | `LDL0020` | | At settlement time, Núclea orders the transfer to the creditors. |
| 8 | STR (BACEN) | Lerian | `LDL0020R2` | | If your institution is a creditor, STR reports the credit in its reserve account. |
| 9 | Lerian | Your institution | Lerian API | Pending | Lerian publishes the card cycle credit. |
| 10 | Núclea | STR (BACEN) | `LDL0006` | | If your institution deposited more than the new amount, Núclea refunds the excess. |
| 11 | STR (BACEN) | Lerian | `LDL0006R2` | | STR reports the refund. |
| 12 | Lerian | Your institution | Lerian API | Pending | Lerian publishes the refund. |

Until the deposit through Lerian is available, your institution sends `LDL0022` on its own STR connection and records the result with [`POST /v1/funding/settlement-instructions/{instructionId}/ack`](/en/reference/rails/slc/record-funding-ack).

### CRC adjustment

| # | From | To | Message | Lerian API | What happens |
| - | - | - | - | - | - |
| 1 | Núclea | Lerian | `LTR0001` | | Núclea creates a mandatory bilateral adjustment (`SubTpAtv=CRC`) for the amounts the defaulter left open. |
| 2 | Lerian | Your institution | Lerian API | [`GET /v1/lbtr/results`](/en/reference/rails/slc/list-lbtr-results) | Read the announced adjustment and its amount. |
| 3 | Your institution | Lerian | Lerian API | [`POST /v1/lbtr/results/{resultId}/decision`](/en/reference/rails/slc/decide-lbtr-result) | Agree or dispute by 10:00 or 17:30. |
| 4 | Lerian | Núclea | `LTR0002` | | Lerian sends your answer to Núclea. |
| 5 | Your institution | Lerian | Lerian API | [`POST /v1/str/operations/ltr-transfers`](/en/reference/rails/spb/create-ltr-transfer) | If your institution is the debtor of the adjustment, command the payment. |
| 6 | Lerian | STR (BACEN) | `LTR0004` | | Lerian pays into Núclea's settlement account. |
| 7 | STR (BACEN) | Lerian | `LTR0004R1` | | STR returns the result of the payment. |
| 8 | Núclea | STR (BACEN) | `LTR0005` | | If your institution is the creditor of the adjustment, Núclea orders the credit after the debtor pays. |
| 9 | STR (BACEN) | Lerian | `LTR0005R2` | Pending | STR reports the credit in your institution's reserve account. |

## How you know it finished

***

The new `LDL0021` acknowledged, plus the evidence for your side of each step. As a debtor: `LDL0022R1` for the deposit and `LTR0004R1` for each `CRC` adjustment paid. As a creditor: `LDL0020R2` for the recalculated balance and `LTR0005R2` for each `CRC` adjustment received.
