In this paper, we use a Lévy process to model the surplus flow of an insurance company. It is assumed that the surplus level is observed at a sequence of fixed times and dividend decisions are made at each observation time. If the observed surplus level is larger than a given barrier, then the excess amount would be paid off as a lump sum of dividends. Further, we assume that ruin is declared as soon as the observed surplus level is negative. Using the Fourier cosine series expansion method, we propose some numerical methods for computing the finite-time expected discounted dividend payments before ruin and the finite-time expected discounted penalty function. Both error analysis and numerical examples are given to show accuracy and efficiency of our method.
