When assessing asbestos and environmental exposures, you need a year-by-year view of how the reserves evolve. For the five most current calendar years, the essential data to present for each exposure on both a gross and a net basis are four line items: beginning reserves, incurred losses and LAE, current-year payments for loss and LAE, and ending reserves. Beginning reserves set the starting point for the year; incurred losses and LAE capture what the company accrues during the year; payments made during the year reduce the reserve; ending reserves show the remaining liability.

Presenting these four pieces for each year across five years lets you see how much is added each year, how much is paid, and how the remaining reserve changes over time, which is exactly what you need to understand development and tail risk. The approach works for both gross and net because you apply the same structure to each, with net amounts reflecting recoveries (reinsurance, etc.) to arrive at net exposure. Other options omit key components (like the annual incurred and payments), so they don’t provide the full view of yearly development.
