## Special Case 1: Annual Lease Rental Not Given
### When does this arise?
The question gives you the Fair Value of the asset but does not state the annual lease rental. The lease rentals are missing.
### Underlying Assumption
> The lessor prices the lease so that the Fair Value of the asset is fully recovered through the present value of future cash flows:
>
> `Fair Value = PV of MLP + PV of UGRY`
This is equivalent to saying: Net Investment = Fair Value on Day 1.

### Step-by-Step Method to Find Annual Lease Rent (LR)
Step 1 – Isolate PV of MLP
```
PV of MLP = Fair Value − PV of UGRY
```
Step 2 – Find Annual LR using Annuity Factor
If the lease rentals are a uniform annual amount:
```
PV of MLP = Annual LR × Annuity Factor (n years, r%)
∴ Annual LR = PV of MLP ÷ Annuity Factor
```
Step 3 – Compute Gross Investment, Net Investment, UFI as normal
```
GI = (Annual LR × n) + GRV + UGRY [face values]
NI = Fair Value (= PV of MLP + PV of UGRY)
UFI = GI − NI
```

### What is the Annuity Factor?
The annuity factor for n years at rate r% is simply the sum of individual discount factors:
```
Annuity Factor = DF₁ + DF₂ + … + DFₙ
= PV of ₹1 received each year for n years
```
