We derive an integrodifferential equation satisfied by the expectation of the discounted dividends until ruin. The case when profits follow an exponential distribution is solved. %K Threshold Strategy %K Dual Risk Model %K Generalized Erlang (n) Risk Process %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=5189
