In this part the question asked why 92.5% combined ratio is in appropriate...
The solutions has given formula of combined ratio and explained that due to difference in denominators, the target ratio is likely to be distorted by difference between two. In the case of question because
(1) some premiums are earned in old basis, thereby reducing the earned premium amount... (I don't get how this mechanics works. I thought the UPR is determined by written premium and time that policies are written. Does change in basis impact the earned proportion?)
(2) The volume of business written may not remain constant. (Again how does it affect the combined ratio?)
Thanks
