MidWestOne Financial Group, Inc. 401(k) Plan Document Summary

Part I of this document consists of performance information for the plan’s investment options, and fees associated with those investments. In addition, Part I shows  how well the investments have performed in the past and compares the returns with an industry benchmark. Part II provides detailed information on the plan‐level  and individual fees that may be charged to your account.    Part I. Investment Information Your plan gives you the right to direct the investment of your account balance. To make a change to your investment elections, log into your account at  www.americantrustretirement.com; under Transactions, click Manage Investments ; under Change Elections, click Get Started .  The table below provides a list of the Designated Investment Alternatives (options) available to you under the plan and how these options have performed over time.  In addition, this table allows you to compare each investment type with an appropriate benchmark for the same timeframe. Past performance does not guarantee  how the investment option will perform in the future, and your investment in these options could lose money. Information about an option’s principal risks is available  in the investment’s fund fact sheet, as well as the fund’s prospectus. This information can be obtained by logging into your account at  www.americantrustretirement.com or calling American Trust at 800.548.2994 or contacting your plan administrator.  This table also provides the fee and expense information for each investment option. The Total Annual Operating Expenses are expenses that reduce the rate of return  of the investment option. This expense is expressed as a percentage, as well as the cost per $1,000 of investment. The Shareholder‐Type Fee is any fee charged against  your investment for purchase and sale other than the Total Annual Operating Expenses.
