Following is a description of the valuation methodologies used for pension plan assets measured at fair value on a recurring basis, as well as the general classification of pension plan assets pursuant to the valuation hierarchy. Where quoted market prices are available in an active market, plan assets are classified within Level 1 of the valuation hierarchy. Level 1 plan assets total $92.0 million and $85.0 million as of December 31, 2021 and 2020, respectively, and include cash and cash equivalents, common stocks, mutual funds and corporate bonds and notes. If quoted market prices are not available, then fair values are estimated by using pricing models, quoted prices of plan assets with similar characteristics or discounted cash flows. Level 2 plan assets total $2.6 million and $3.5 million as of December 31, 2021 and 2020, respectively, and include governmental agencies, taxable municipal bonds and notes, and certificates of deposit. In certain cases where Level 1 or Level 2 inputs are not available, plan assets are classified within Level 3 of the hierarchy. There are no assets classified within Level 3 of the hierarchy at December 31, 2021 and 2020.
