The dollar amount reported in column (d) represents the average of the amounts reported for the Company’s named executed officers (“NEOs”) as a group in the “Total” column of the Summary Compensation Table in each applicable year. The names of each of the NEOs included for purposes of calculating the average amounts in each applicable year are as follows: (i) for 2022, Brandon M. Gall, David S. Bratcher, David E. Dykstra, Stephen J. Glaser, Amel Pasagic, and Erika Lapish; (ii) for 2021, Brandon M. Gall, David S. Bratcher, David E. Dykstra, and Stephen Glaser; and (iii) for 2020, Brandon M. Gall, David E.

The dollar amounts do not reflect the actual average amount of compensation earned by or paid to the NEOs as a group (excluding Mr. Griffin and Mr. Colo) during the applicable year. In accordance with the requirements of Item 402(v) of Regulation S-K, the following adjustments were made to average total compensation for the NEOs as a group for each year to determine the compensation actually paid, using the same methodology described above in Note 2. | | | |

| Compensation Actually Paid vs. Total Shareholder Return [Text Block] | | Compensation Actually Paid and Cumulative TSR As demonstrated by the following graph, the amount of compensation actually paid to Mr. Colo and Mr. Griffin and the average amount of compensation actually paid to the Company’s NEOs as a group (excluding Mr. Colo and Mr. Griffin) is aligned with the Company’s cumulative TSR over the three years presented in the table. The alignment of compensation actually paid with the Company’s cumulative TSR over the period presented is because a significant portion of the compensation actually paid to Mr. Colo, Mr. Griffin and the other NEOs is comprised of equity awards. As described in more detail in the section “Compensation Discussion and Analysis,” the Company’s compensation program objectives are to align compensation program with our business objectives and stockholders’ interests, to reward performance, to be externally competitive and internally equitable, and to retain talent on a long-term basis. In particular, our philosophy is to balance salary and benefits with incentive and equity compensation so that the interests of the executive officers will be aligned with those of stockholders. | | | |
| Compensation Actually Paid vs. Net Income [Text Block] | | Compensation Actually Paid and Net Income As demonstrated by the following graph, the amount of compensation actually paid to Mr. Colo and Mr. Griffin and the average amount of compensation actually paid to the Company’s NEOs as a group (excluding Mr. Colo and Mr. Griffin) is generally aligned with the Company’s net income over the three years presented in the table. While the Company does not use net income as a performance measure in the overall executive compensation program, the measure of net income is correlated with the measure of Adjusted Operating Income, which the Company uses when setting goals in the Company’s short-term incentive and long-term incentive compensation programs. | | | |
| Compensation Actually Paid vs. Company Selected Measure [Text Block] | | Compensation Actually Paid and Adjusted Operating Income As demonstrated by the following graph, the amount of compensation actually paid to Mr. Colo and Mr. Griffin and the average amount of compensation actually paid to the Company’s NEOs as a group (excluding Mr. Colo and Mr. Griffin) is generally aligned with the Company’s Adjusted Operating Income over the three years presented in the table. While the Company uses several financial and non-financial performance measures for the purpose of evaluating performance for the Company’s compensation programs, the Company has determined that Adjusted Operating Income is the financial performance measure that, in the Company’s assessment, represents the most important performance measure used by the Company to link compensation actually paid to the Company’s NEOs, for the most recently completed fiscal year, to Company performance. | | | |
| Total Shareholder Return Vs Peer Group [Text Block] | | Cumulative TSR of the Company and Cumulative TSR of the Peer Group As demonstrated by the following graph, the Company’s cumulative TSR over the three-year period presented in the table was $208.52, while the cumulative TSR of the peer group presented for this purpose, Russell 2000 – Consumer Staples (line of business comparison), was $106.67 over the three years presented in the table. | | | |
