I'm not aware of any companies that do profitability by product.... most often by product line and perhaps contribution by product for the players who really have their act together. Unless you were privy to the product pricing or subsequent actual to expected studies you have no way of know whether they are making money on the product or not... only company insiders would have access to that information.
Prudential isn't stupid... I'm sure that they are pricing the product for a profit and mortality is quite predictable.
