The timeliness of financial-modeling systems used by life insurance companies is seen as less than optimal, with 13% of chief financial officers saying they are "extremely satisfied" with how long it takes to get and interpret results, according to a Towers Watson study. Seventeen percent said they were "not at all satisfied." Half of respondents said their models yield results within a week, and 41% said they get results within a month, but 91% said it takes additional time to interpret the results.
