• Cat ProActive Price Monitor
  by Richard M. Cundy, FCAS

  The program is window-based and available in ZIP format and is easily installed when the program is unzipped by running SETUP from Windows. The zipfile size is ~4mb and the additional documentation files add another ~300kb. This a true 32-bit application, thus no Window 3.1 users. The program provides a front-end underwriting tool and back-end monitoring tool for use by underwriters and management to make informed decisions when writing Property Catastrophe Exposures. The tool assumes that the user has acquired the use of a simulation model, such as Catmap, RMS or similar programs that provide expected losses and standard deviations. Reports on the book of business can easily be created by importing the database files into Excel or Lotus.

• Aggregate Loss Distribution Builder
  by Hou-wen Jeng

  This software is provided as a zipped file of size 6.5MB. It unpacks into 10 files; double-click setup.exe to run the program. This updated software is designed to build aggregate loss distributions based on the collective risk model. Most calculations can be completed in less than 10 seconds (with a Pentium II 450/64 MB memory). You have the choice of using either Simulation or two approximation methods - Recursion and Fast Fourier Transform - to build your aggregate loss distributions.

  The two choices for frequency distributions are Poisson and Negative Binomial while there are five severity distributions -Exponential, Gamma, LogNormal, Weibull, and Pareto- for the user to choose from. The software presents the results in both tabular and graphic forms. The user can print the summary results or export the results to MS Excel. If you need more specific information about the resulting aggregate loss distributions, please contact Hou-wen Jeng at hjeng@columbus.rr.com.

• Software for Fourier Methods of Calculating Aggregate Loss Distributions
  by Glenn Meyers

  The spreadsheet FFTCalc provides an introduction to Fourier methods for aggregate loss distributions. It provides a step by step explanation of the process. It also illustrates the FFT methodology developed by Shaun Wang to include correlation beween the frequency distribution of two lines of insurance.

• Bond Analytics Program, Version 2.03a
  by Thomas P. Hughes

  The Bond Analytics Program is a fixed income analytics program for computing bond yields, price-yield volatility metrics and horizon analyses. Options include an external reinvestment rate, tax rates, horizon and call calculations and odd first coupon periods. The program has an easy to use single screen user interface featuring pop-up Help windows and extensive diagnostic messages. A User Guide text file gives more detailed information about the program and bond analytics in general. This is not a .pdf file, it is a zipped file (77KB) containing a .txt file and an executable file.

• Seabury and Smith Experience Analysis System (SSEAS)

  SSEAS is a complete loss reserving system able to do side-by-side comparisons using chain-ladder, Bornhuetter-Ferguson and numerous other estimators. It can perform Monte-Carlo simulations extending Stanard's model in PCAS LXXII. It runs under DOS or in a DOS session under OS/2 or Windows 3.1 or higher. This is the complete DOS version of SSEAS, release 7.24, and may be used for study or research with no restrictions. The software is provided as a zipped file of size 1,169,013 bytes. It unpacks into the files sseas.exe and readme.1st; to install, follow the instructions in the latter file.
