Based on the findings of prior analytical and empirical research, we formulate and test hypotheses about the likelihood of voluntary CAP participation and the resulting effect on FIN 48 tax reserves. We find that firms with moderate-sized FIN 48 reserves are more likely to participate in CAP than firms with either small or large reserves, indicating an inverted U-shaped relation between CAP participation rates and firms' tax reserves. After controlling for non-random sample selection, we find that CAP firms significantly reduce their FIN 48 reserves by about 16.5 percent relative to non-CAP firms. However, this reduction is concentrated among firms with moderate-sized FIN 48 reserves. These cross-sectional differences are consistent with FIN 48 reserves reflecting both tax uncertainty and tax aggressiveness
