1. Is it possible to simultaneously use different database systems?

RE uses a single database per instance user, e.g.company or department. A set of company users is defined in the company’s database (instance user) and uses data from this database alone. If a different set of users within the organisation needs to access another database, a separate instance of RE has to be started or a new instance user (department) has to be configured.

2. Which WEB browsers are supported in the WEB GUI?

All standard browsers are supported, including Internet Explorer 9+, Mozilla Firefox, Google Chrome, Sea Monkey, Opera, Safari for PCs, tablets and smart phones. The GUI uses HTML and JavaScript only, without any external dependencies.

3. What is the RE license policy?

Each module is enabled or restricted with separate licenses and thus allows customers to pay only for modules they really need. The licenses can be configured to be either time restricted or not. It is also possible to aquire a test license and thus get free access to all modules for a limited period of time in order to test their usability.

4. What is a Rule-Based Instrument?

A tool that calculates complex, structured, exotic and non-standard instruments, that display a future path-dependent behavior, e.g., in cases where future cash flows and pay offs depend on other future events. The evaluation of such instruments may require a Monte Carlo simulation of one or several factors at different future time points. The simulation structure is explicitly defined by periods and pricing formulas per factor, as well as by simulation markets.
Example: A 4-year loan can be paid back at the end of every year,up to a maximum amount of 50%. If the entire 100% are paid in the first two years, then there is nothing to be paid back in year 3 and 4. But if, e.g., 20% is paid in the first year and 25% in the second, then a lot of payback variations exit for year 3 and 4.

5. What is the difference between Standard, Rule-Based and Multi-Factor Instruments?

• Standard Instruments - Contract conditions are simple; instruments are known on the stock exchange; direct implementation brings high performance.
• Rule Based Instruments - See FAQ 4.; the instruments are defined by a simulation structure, using exact contract conditions, given mostly in term sheets.
• Multi-Factor Instruments - If term sheets do not exist and contract conditions are unknown, the evaluation can be based on existing historical price time series for the instrument. The approach is to map this historical price time series to other well-known time series, e.g. to FX-Rates, indexes, interest rates, price of other known instruments, etc. This can be achieved by using regression and by defining automatic pricing expressions for the unknown instrument. The pricing expression, along with the included known time series, make the unknown instrument known and enable the performance of all sorts of analysis, including VaR.
