 of significant input determines the placement of the entire fair value measurement in the hierarchy.

The Plan’s policy is to recognize transfers between levels of the fair value hierarchy as of the end of the reporting period.

The following descriptions of the valuation methods and assumptions used by the Plan to estimate the fair values of investments apply to investments held directly by the Plan. Registered investment companies and Company stock: The fair values of Registered investment companies and Company stock investments are determined by obtaining quoted prices on nationally recognized securities exchanges (Level 1 inputs). Common/Collective trusts: The fair values of participation units held in the common/collective trusts are based on their net asset values (“NAV”), as reported by the managers of the common/collective trusts and as supported by the fair value of the trusts’ underlying net assets, and by the unit prices of actual purchase and sale transactions occurring as of or close to the financial statement date. The investment objectives and underlying investments of the common/collective trusts vary. The Plan invests in various common/collective trusts within the Old Second National Bank of Aurora Common Trust Fund for Corporate Retirement Plans, including the Diversified Equity Portfolio and Strategic Dividend Fund common/collective trusts (“equity” funds) which are comprised of a diversified portfolio of common stocks, both domestic and international, as well as open-ended mutual funds. The Bond Fund common/collective trust (“bond” fund) invests in individual fixed income securities issued by the U.S. Government, government agencies, and corporations. In addition, there is an asset allocation collective trust, the Balanced Fund, that is comprised primarily of a different mix of the equity and bond funds discussed above. Each of the common/collective trusts discussed above provides for daily redemptions by the Plan at reported net asset value per unit. In the event the Plan was to initiate a full redemption of the collective trusts, the investment advisor will ensure that securities liquidations will be carried out in an orderly manner. The Plan also invests in the Federated Capital Preservation Trust Fund common/collective trust (the Stable Value fund) which holds guaranteed investment contracts (traditional GICs), separate account guaranteed investment contracts (separate account GICs) and synthetic guaranteed investment contracts (synthetic GICs). Participants may purchase units of the Stable Value fund daily based on the established unit value of $10.00. Participants may redeem units of the Stable Value fund for the purpose of funding a benefit payment, funding a participant note
