With extensive experience in employee benefits, estate planning and tax law, Tom Mug is a go-to resource for a number of public and private employers of all sizes. Key areas of his practice include designing, implementing and maintaining Employee Stock Ownership Plans (ESOPs) and advising on government retirement plan issues.
ESOPs. When a business owner wants to set up a plan to shift ownership interests to employees, Tom can assist with the ESOP process from start to finish — discussing how the transaction will work, negotiating with the plan’s designated trustee and closing the deal. He works with companies maintaining existing ESOPs and counsels ESOP trustees and lenders. Tom is a sought after national speaker on ESOP topics and is active in the ESOP Association and National Center for Employee Ownership.
Government pensions. Tom advises on government retirement plan issues. He represents municipalities and other local governmental entities, including local housing authorities and fire protection districts, on compliance issues and the administration of qualified and non-qualified retirement plans. He is a member of the Missouri Association of Public Employee Retirement Systems (MAPERS).
Other employee benefits. Representing employers, qualified plan fiduciaries and industry associations, Tom assists with the design and operation of employee benefit plans and executive compensation arrangements. He advises on 401(k), profit-sharing, defined benefit pension and 403(b) plans, including issues of plan qualification and the duties of plan fiduciaries. He works with clients to provide creative solutions in incentive compensation, equity compensation and other non-qualified programs and assists with fringe benefit programs, health plans and COBRA compliance.
Estate planning. Individuals consult with Tom on their needs and wishes in developing personal estate plans. By preparing documents including wills, trusts, powers of attorney and health care directives, as well as advising on tax issues, charitable planning and advanced estate planning techniques, he provides clients with the counsel needed to ensure their affairs are in order.
Business planning. In conjunction with his practice, Tom advises owners of closely held businesses on business succession, compensation planning, shareholder issues (including buy-sell agreements), tax issues and transactional matters.
