Most companies with an employee stock ownership plan (ESOP) either sponsor a separate 401(k) plan or combine ESOP and 401(k) components together under the umbrella of a single plan arrangement known as a KSOP. The combination of plans offers employees the ability to diversify the investment of their retirement savings through the 401(k) arrangement while enjoying the benefits of ownership through the ESOP. However, many administrative and legal issues arise, and it is crucial for both companies and service providers to understand them, beginning in the plan design stage. The new fee disclosure rules that became effective in 2012 only added to those issues. This publication, written by three experienced practitioners with backgrounds ranging from law to administration, discusses a wide range of essential issues and the best practices for dealing with them.
