Abstract: A computer system includes a web server component and a rules engine component in communication with the web server component. The rules engine component receives input rating information that is relevant to insurance coverage rating decisions. The rules engine component applies rating rules to the input rating information to generate premium quotations for a proposed insurance policy. The web server component downloads a quotation display page to a client computer. The quotation display page includes two different quotation sections positioned side-by-side. Each quotation section provides a different premium quotation, with the premium quotations based on mutually different sets of input rating information.
