(5) For purposes of this disclosure, the peer group is the S&P 600 SmallCap Materials Index.. (6) Net income (loss) is calculated in accordance with GAAP, as previously reported.

The table above also describes the relationship between our one-, two-, three-, four- and five-year cumulative TSR compared to the weighted average one-, two-, three-, four- and five-year cumulative TSR of the companies in the S&P SmallCap 600 Materials Index. Our TSR during 2020 through 2022 was impacted by a series of external issues and challenges initiating with the onset of the COVID-19 pandemic late in the first quarter of 2020 that negatively impacted the end markets for many of our products, including large commercial aerospace applications. In addition, while the S&P SmallCap 600 Materials Index reflects our industry sector, many of the companies included in the index were not as heavily impacted by the COVID-19 pandemic related impact on the aerospace industry. |  |  |  |
