Policy year information reflects an actuarial perspective or look at what
has happened to a particular policy year over time. A policy year is based
on policies with effective dates in a twelve month period. So, policy year
2000 data are those policies with effective dates between 1/1/00 and 12/31/
00. For example, if you look at policy year 2000 today, it would have
everything that had developed on a policy since 2000; all losses, premiums,
reserves, expenses, allowances, etc. up to this point in time.
Accident year data is based on accidents that occur within a twelve month
period. Thus, accident year 2000 is based on those accidents that occurred
between 1/1/00 and 12/31/00.
To compare, a policy could be effective 9/1/00 and an accident could occur
on 2/1/01. The loss would be included in policy year 2000 and accident year
2001. If the loss occurred on 12/1/00, the amount would be reported in
policy year 2000 and also in accident year 2000.
Calendar year information in contrast, is more from an accounting
perspective and contains information about each policy year. For example,
policy years 1980-1998 could all have transactions going on in calendar year
1998, and that is what calendar year information is showing - many policy
years with activity within one calendar year.
Looking at policy year 1980 in calendar year 1998, we would not likely see
any premium activity still occurring during 1998, but we would still see
loss activity. So the results for calendar year 1998 would include that loss
information for policy year 1980, along with the loss information for all
other policy years that had transactions during the 1998 year. As we
approach the more current policy years, we would also see more premium
activity going on for those years as well as loss activity. | I**R

half a year more mature than policy year. But that depends on specific book
of business. |
