This information asymmetry situation can provide opportunities for each party to achieve its personal interests, so that it can cause underpricing conditions. This research aims to analyze the effect of financial leverage, return on assets (ROA), ownership concentration, inflation rate, and listing delay on the level of underpricing both simultaneously and partially.

Data analysis that used is panelpooled data regression analysis using eviews software 9.0 version.The result of the study showed that financial leverage, ROA, ownership concentration, inflation rate, and listing delay simultaneously had an effect on the level of underpricing. While partially, ROA has a negative effect on the level of underpricing. Inflation rate has a positive effect on the level of underpricing. While financial leverage, ownership concentraion, and listing delay did not affect on the level of underpricing partially.
