i referred to reserves as:
reserves = pv of future benefits + pv of future expenses - pv of future premium
(stressing benefits and premiums as the major components)
then i mentioned how surplus is required. this is my reasoning for why it is not unusual for assets to dwarf liabilities.
i also mentioned rbc and dac tax. left out tax reserves and aat (still dont know wtf this is).
the whole module must be 4 pages so i tried to be brief.
