When redeemed early by the user 
When redeemed by liquidation 
Redeemed amount 
1. WhaleFin only supports the user to enter redeemed principal, and will automatically calculate the redeemed interest and the bonus interest. 2. Maximum redeemable principal amount = remaining principal amount 3. Users are not allowed to redeem their assets when the following conditions are met:

Liquidation order: the assets will be redeemed pro rata based on the principal + accrued interest + bonus interest 
Redeemed interest 
Recalculated based on (redeemed interest * 0.5% APR * holding days / 365), and the excess portion will be deducted as penalty/transaction fees 
Remains unchanged (no penalty) 
Bonus interest 
1. The settled portion will be redeemed pro rata 2. The remaining portion will not be settled (in case of interest arbitrage) 
1. The settled portion will be redeemed pro rata 2. The remaining portion will still be settled according to the original coupon rules

Remaining principal after redemption 
Calculated at the original APR 
Calculated at the original APR and the original coupon rules (if any coupon is used) 
Example:
If user A subscribes to the Earn product [BTC30 days5%] on 04/01 with 10 BTC, and applies a 1% bonus interest coupon that is valid for 15 days; and user A redeems 5 BTC on 04/10, then:
1. Redeemed principal = 5 BTC
2. Accrued interest = Early redeemed principal * 0.5% * Holding days / 365 = 5 * 0.5% * 10 / 365 = 0.00068493
3. Accrued bonus = (Early redeemed principal amount / Principal) * Accrued interest before first redemption = (5 / 10) * 10 * 1% * 10 / 365 = 0.001369863013699
4. Actual redeemed amount = Early redeemed principal amount + (Early redeemed principal amount * 0.5% * Holding days / 365) + (Early redeemed principal amount / Principal) * Realized coupon APR = 5 + 0.00068493 + 0.001369863013699 = 5.002054793013699
5. After early redemption:

 The bonus interest coupon is invalid, i.e. the coupon is 5 days from expiry, and the remaining portion of interest will not be settled
 The remaining principal of 5 BTC will be settled at 5%, the original APR
