Abstract: The disclosed technology relates generally to a method and system for providing exchange traded funds (ETFs) as investment options for individual account retirement plans. Participants may purchase, in certain embodiments, ETFs, mutual funds, collective investment trusts or other investments for their retirement plan accounts. The disclosed technology provides participants with the ability to purchase ETFs for their retirement account and benefit from these advantages. The disclosed technology enables participants to be allocated fractional shares—thus allowing them to purchase and sell a desired number of shares without having to round their purchase to the nearest whole share. Instead, a house account is used to purchase or sell the number of shares necessary to execute a whole share transaction. This provides participants with increased flexibility from low investment costs and broad investment choices—gaining the ability to more precisely tailor their retirement investments and save more for retirement.
