AJ Important ones that need to be stated¶ Trending¶ There's an apparent downward trend in LDFs. I'll select a 2 year average to be responsive, but not overly reactive. Development¶ Disposal Rates¶ Disposal rates have been trending down, perhaps due to a slowdown in closing claims. I'll select the latest 3 year average to be slightly more responsive but conservative in case the trend doesn't continue. UW expenses¶ I assume premium is trending at the same rate as fixed expenses, so no need to trend fixed expense ratios. For simplicity without loss of much accuracy, I’ll trend all fixed expenses using average written dates.
