I have known Bob since 1989. He and I worked together closely on a series of tax appeals and audits, particularly during the 1989-93 period. During this time Bob, working either with me or my partners, negotiated with senior Department of Revenue personnel in ten states to limit back filing to 4 years from potentially 20 years – to obtain favorable apportionment factors and non-business income treatment for interest income and sales of assets in several states. In several cases we were able, under the current laws then in place, to successfully disclaim nexus, saving over $3,000,000 a year. In the years that I have known Bob I have been impressed by his strong work ethic, ability to research complex issues and arrive at solid conclusions. He has been a pleasure to work with.
