Our methodologies for determining the fair value of equity awards in our financial statements and in the Summary Compensation Table and Grants of Plan-Based Awards Table above are described in Note 16, “Stock Based Compensation Plans,” to our consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023, and in footnote (2) to the Summary Compensation Table. For purposes of calculating compensation actually paid in this section, awards of RSUs are valued at fiscal year-end dates and vesting dates based on the closing market price of our common stock at each such measurement date, based on target shares as adjusted at any vesting date for earned above-target shares or forfeitures. |  |  |

Compensation Actually Paid vs. Total Shareholder Return | As required by Section 953(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(v) of Regulation S-K, we are providing the following information about the relationship between executive compensation and certain aspects of the Company’s financial performance. For further information regarding our executive compensation programs, the metrics the Compensation Committee used to set executive compensation for 2023 (which are different than the financial metrics we are required to include in the tables and discussion below) and our pay versus performance philosophy, please refer to “Compensation Discussion and Analysis” starting on page 20 of this Proxy Statement.
| ​ | ​ | Financial Metrics | ​ | ​ |  | ​ | ​ | Comp Actually Paid
Year | ​ | ​ | TSR | ​ | ​ | Net Income | ​ | ​ | PEO Compensation | ​ | ​ | Non-PEO Compensation
2023 | ​ | ​ | 6.2% | ​ | ​ | -69% | ​ | ​ | 1915.0% | ​ | ​ | 41.2%
2022 | ​ | ​ | -37.0% | ​ | ​ | 27% | ​ | ​ | -98.8% | ​ | ​ | -73.9%
2021 | ​ | ​ | 134.0% | ​ | ​ | 464% | ​ | ​ | 176.3% | ​ | ​ | 62.1%
2020 | ​ | ​ | 29.6% | ​ | ​ | -18% | ​ | ​ | 153.6% | ​ | ​ | -31.0%
We believe that the Company’s total shareholder return and profitability are important in the design of our compensation programs. Since 2020, cumulative total shareholder return is approximately 55%. Our 2023 net income is 123% higher than in 2020 and our 2023 Adjusted EBITDA is 33% higher than in 2020. The ‘compensation actually paid’ to our PEO has varied significantly from year to year but is now 66% of the amount in 2020. For the non-PEO Named Executive Officers, this ‘compensation actually paid’ is 60% of the amount in 2020. Therefore, PEO and non-PEO Named Executive Officer compensation is modest relative to above returns. Approximately 70% of the total direct compensation of our PEO and 55% of the total direct compensation of our Non-PEOs is variable or “at risk” and therefore changes in share price can significantly impact “compensation actually paid”. The Compensation Committee believes that 2023 compensation decisions for the PEO and Non-PEOs are reflective of the Company’s overall operating, strategic, finance and stock price performance and thus aligned with shareholders. Pay Versus Performance Alignment In linking pay and performance, the Compensation Committee intends to align executive pay with stockholders’ interests. A substantial portion of compensation is determined by the creation of stockholder value. In addition to adopting share ownership guidelines that are described elsewhere in this Proxy Statement, ISG focuses on the measures of revenue, adjusted EBITDA and total shareholder return. The values in the Pay Versus Performance table above show the impact of share price on the ‘actual compensation paid.’ In determining Named Executive Officer compensation for a particular year, the Compensation Committee conducts a broad review of ISG performance relative to budget plans and considers general market conditions. In addition, the Compensation Committee also considers performance against operating and strategic goals. We believe that this provides an appropriate holistic view of firm performance. |  |  |

Total Shareholder Return Vs Peer Group | The following table compares the 4 year cumulative total shareholder return on our common stock from December 31, 2019 through December 31, 2023, with the cumulative total return for the same period of the Peer Group described below. The comparison assumes for the same period the investment of $100 on December 31, 2019 in our common stock and of the peer group and in each case, assumes reinvestment of all dividends.

Since 2020, ISG’s return has outperformed its peer group and resulted in a more than 55% cumulative return during that time period. As noted in the pay versus performance table, annual compensation actually paid to the PEO and non-PEO Named Executive Officers has declined during that same time period. |  |  |
