A former broker won a $600,000 arbitration award for claims that another broker reneged on a deal to sell his book of business. According to a Financial Industry Regulatory Authority Inc. filing, former Ameriprise Financial Services broker Peter Butler acquired the business of another Ameriprise broker, Craig Wiggins. Mr. Butler claims Mr. Wiggins tried to recapture the clients after he learned that Mr. Butler intended to resell the business to a third party. Mr. Butler alleges Mr. Wiggins contacted the clients and transferred them back to his own firm, Financial Management Strategies, with the help of his new broker-dealer, Cetera Financial Services. Mr. Butler initially sought damages of at least $975,000 for breach of contract, misappropriation of trade secrets, breach of fiduciary duty, civil conspiracy, unjust enrichment, interference with contractual relationships and violation of Finra Rule 2010.
