calculateWritedownFor

function calculateWritedownFor(contract ICreditLine cl, uint256 timestamp, uint256 gracePeriodInDays, uint256 maxDaysLate) public view returns (uint256, uint256)

calculateWritedownForPrincipal

function calculateWritedownForPrincipal(contract ICreditLine cl, uint256 principal, uint256 timestamp, uint256 gracePeriodInDays, uint256 maxDaysLate) public view returns (uint256, uint256)

calculateAmountOwedForOneDay

function calculateAmountOwedForOneDay(contract ICreditLine cl) public view returns (struct FixedPoint.Unsigned)

splitPayment

function splitPayment(uint256 paymentAmount, uint256 balance, uint256 interestOwed, uint256 interestAccrued, uint256 principalOwed) external pure returns (uint256 interestPayment, uint256 principalPayment)

Given a lump sum, returns the amount of the payment that should be allocated to paying interest, and the amount that should be allocated to paying principal

allocatePayment

function allocatePayment(struct Accountant.AllocatePaymentParams params) public pure returns (struct ILoan.PaymentAllocation)

Allocate a payment.

1. interestOwed must be paid before principalOwed
2. principalOwed must be paid before interestAccrued
3. interestAccrued must be paid before the rest of the balance

IO - Interest Owed PO - Principal Owed AI - Accrued Interest
