Abstract

ABSTRACT Dividends are one of the reasons why people buy stocks. However, different research always produce varied results when it comes to the factors that determine a company's dividend policy. The purpose of this study is to re-examine the factors that influence corporate dividend policies, particularly those of companies that consistently give substantial dividends, using changes in the dividend tax rate specified in PMK No.18 of 2021 as the moderating variable. As the object of this study, companies featured in the IDX High Dividend 20 index are used. From 2018 through 2021, 12 companies that fit the criteria were examined as samples and assessed using Moderated Regression Analysis. The research results show that profitability, capital structure, company growth and managerial share ownership are able to influence the IDX High Dividend 20 company's dividend policy, but only profitability and capital structure are able to partially influence dividend policy. The dividend tax rate has not been able to become a moderating variable, which due to the lack of reaction from investors and management in responding to these regulations. This lack of reaction is likely due to the dividend tax exemption requirements which require investors to re-invest dividends received for at least 3 years in domestic investment instruments.

Abstract

ABSTRACT This study aimed to examine the effect of Cash Conversion Cycle (CCC), Stock Conversion Period (SCP), Average Collection Period (ACP), Payable Deferral Period (PDP), and Net Receivable Period (NRP) on the performance of manufacturing companies listed on the Indonesia Stock Exchange. Company performance was measured by Return on Assets (ROA) which described accounting-based performance and the Tobin's Q (TQ) ratio which described market-based performance. This study also added Current Ratio (CR), Leverage (LEV), and Firm Size (SZ) as control variables. The population used in this study was manufacturing companies listed on the Indonesia Stock Exchange (IDX) for the 2015 to 2021 period. The number of samples used was 120 companies which were taken using a purposive sampling method. The analytical method used was panel data regression with the addition of the Robust Standard Error procedure to overcome the heteroscedasticity problem in the Fixed Effect Model (FEM). The results showed that CCC and SCP had a significant negative effect on both measures of firm performance. PDP was found to have a significant negative effect on ROA, but a significant positive effect on market size. ACP had a negative effect on both measures of firm performance, but not supported by statistical significance. NRP had an insignificant positive effect on ROA and an insignificant negative effect on TQ. In addition, Firm Size (SZ) had a negative effect on ROA and TQ. CR had a positive effect on both measures of firm performance and LEV was found to have a significant negative effect on ROA and an insignificant positive effect on TQ.
