Ellis products are CGCalc and TaxReporter. CGCalc is a rule-based global tax cost calculation engine. TaxReporter is a highly configurable tax reporting software suite.

The CGCalc engine uses your data, the related tax rule definitions and the relevant corporate action definitions to dynamically derive the correct transaction set that is required to be processed.

The transactions are then processed to compute related tax costs and to populate the derived transactions such as dividends. The results are persisted for use by TaxReporter.
For your convenience and for use in basic valuation reporting, average book costs are also computed.

The CGCalc engine has been developed using the latest design and development techniques. We are distinctly proud of the design of our system. From the outset it had to be efficient enough to cope with the huge quantity of data that we are required to process. Yet the system has to be flexible enough to cater for a multitude of tax jurisdictions and corporate action definitions. We have successfully achieved this with CGCalc whilst at the same time ensuring the system is comfortably maintainable and extensible.
