This refer to a car (used for business purposes) lease originally for three years but terminated early during the first year (within the first year)
Your lease downpayment must be prorated over the length of the lease. Example: your lease is for 5 years, claim 20% of your down payment per year and add that to your "total lease charges paid".
For a three year lease you would 34%, 33% and 33% of your downpayment each year. If you cancelled your lease before it was up, you will have to make a further proration and divide that 34% by 12, then multiply it by the number of months you held the lease.
