# Renegotiation

The **Renegotiation** phase allows the Pool Manager to propose modified loan terms when circumstances change. This can happen from either the **Active** or **Defaulted** phase.

## When to Renegotiate

Renegotiation is useful when:

* The borrower is struggling with payments and needs adjusted terms
* Market conditions have changed and rates need updating
* A defaulted vault can be restructured to resume payments
* The loan term needs to be extended or shortened

## How It Works

### 1. Propose

The Pool Manager calls `propose_renegotiation(caller, new_interest_rate, new_loan_term)`:

* The vault's **previous phase** (Active or Defaulted) is saved
* A `RenegotiationProposal` is stored with the new rate, new term, and timestamp
* The vault transitions to the **Renegotiation** phase

### 2. Approve or Reject

The Pool Manager then either approves or rejects the proposal:

**If approved** (`approve_renegotiation`):

* The vault's interest rate and loan term are updated
* The **EMI is recalculated** based on the **outstanding principal** (not the original principal)
* Payment tracking is reset: `payments_made = 0`, `missed_payments = 0`, `late_fees = 0`
* The **next due date** is set to 30 days from now
* The vault transitions back to **Active**

**If rejected** (`reject_renegotiation`):

* The proposal is discarded
* The vault returns to its **previous phase** (Active or Defaulted)

{% hint style="warning" %}
Only one renegotiation proposal can exist at a time. A new proposal cannot be created while one is pending.
{% endhint %}

## Key Details

* Only the vault's **Pool Manager** can propose, approve, or reject renegotiations
* The EMI recalculation uses the **remaining outstanding principal**, not the original principal — this means the new payment schedule reflects what's actually owed
* Renegotiation from **Defaulted** is particularly powerful — it allows a defaulted vault to be restructured and resume active repayments
