This material assumes that the reader is reasonably knowledgeable of GAAP, GAAS, ERISA, and the IRC as it relates to 401(k) plans. This material focuses on and attempts to meld together the unique ERISA and tax issues involved in the accounting, tax reporting and ultimately the auditing of the financial statements of 401(k) employee benefit plans. Since most practitioners will deal with single employer sponsored 401(k) plans, the materials focus on single employer sponsored plans. This intermediate level course is most appropriate for the professional with detailed knowledge in this topic or the professional seeking to expand his or her knowledge base and who may be at a mid-level position within an organization with operational or supervisory responsibilities, or both.
