yeah, nah
The change from 1 to 2 looks something like:
Grade |
Change |
A1 - A2 |
78% drop |
B1 - B2 |
74% drop |
C1 - C2 |
3% rise |
D1 - D2 |
9% drop |
E1 - E2 |
69% rise |
F1 - F2 |
4% drop |
So I'd say only A and B are showing significant drops from 1 to 2?

I'd agree but the interest charged is somewhat significantly different.. Possibly just statistical noise or bias in our sample. I won't be changing my filters for it.

Could be something to do with scorecard changes or borrower selection or even a shift in grade selection by lenders. Just interesting...
Could be change in Harmoney sales focus and strategy due to Commerce Commission actions/ruling...

The way I'm reading it, your graph is a hazard curve too. It shows that 42% of the defaults in our data pool occurred within the first 15 months of the loan. Harmoney hazard curve (to july 17) stated that almost 60% of the defaults that occurred were within the first 15 months of the loan. Harmoney hazard curve was plotted on maturity approx two-thirds of ours (time wise), which explains some of the improvement in percentage.
I'm getting the distinction you are making, as well as the goal you are aiming at, through Survival rate computation. But how to plot it, given that survival rate gets impacted not just by defaults but by early repaids too? Hmm...

Thanks leesal, very interesting. Also your work on max vs non-max loans, which was supplemented by additional insights from Myles, humvee, Cool Bear and RMJH.
Also interesting was the "grade ceiling overflows" from A limits into the B1 and B2, and B limits into C1, C2 and C4. So, not a ceiling after all, more like a rough guideline...

Some interesting observations emerged as I played around with your trivariate tables today, Myles. For example, while all except 50-59 year olds were high risk when buying new vehicles, all new vehicle buyers in AB grades were cool to loan to (despite small bases by age groups within grade).
Full owners in A grade taking holidays were cool, but in C were high risk. Etc.
While the above 60 wanting loans to buy a new vehicle were not at all cool overall (2 defaults /21 total), we may have to wait until the next data pool to analyze them by grade.
Thanks again for your time and effort in producing and sharing these nevertheless.

Not sure if this has been discussed before so just putting it out there - it's really a question: Is a loan paid off in a shorter period, higher, lower or the same risk/value as a loan paid off over a longer period?

The fact that, on average, a 60 month term loan is paid of in less time than a 36 month term loan is just nuts? Perhaps it's human nature to take the extra time and perhaps most don't realise the extra Interest paid...

My view is that early repayment does not affect the returns or risk. If you accept a certain risk/returns and if the loan is repaid early then you can always invest the proceeds into a similar loan.

Under the original fee structure, early repayment hurt. Not so much now but there is still a re-investment lag. Just to confirm. Your figures represent the average age at which early repaid loans were repaid rather than average loan life? I think that must be the case.

Forgot to say, I think the remainder of the original cohort will become a bit more risky with these early repayments as they are prior to the default peak and thus the bad loans are less diluted.
