Business Team Investment Entrepreneur Trading Concept
Overview
When it comes to assets in company retirement plans based on company plan size, some familiar names lead the list. New data from business intelligence data analytics firm miEdge found that the top 401(k) plans by asset size for companies with more than 1,000 actively enrolled employees hail from IBM Corp., Boeing and Wells Fargo.

The miEdge data comes from Form 5500 filings with the U.S. Department of Labor as of July 30. Government entities such as cities, towns and fire and police departments are not required to file and therefore are not reflected in this data. The same applies to church plans, as defined by ERISA.

Additionally, participation percentages for each company include retired or former employees who have left employment with the company, but still have their plans/balances in, accounting for participation rates of more than 100%.
