The Effect of Working Capital Management on Profitability

The purpose of this study is to find out the effect of working capital management on company profitability. The study aims at examining the statistical significance between company’s working capital management and profitability. In light of this objective the study adopts quantitative approaches to test a series of research hypotheses. A sample of three (3) manufacturing companies listed on the Dar es Salaam Stock Exchange (DSE) is used for a period of ten years (2002-2012) with the total of 30 observations. Data is analyzed on quantitative basis using Pearson’s correlation and Regression analysis (Ordinary Least Square). The key findings from the study are; Firstly, there exists a positive relationship between cash conversion cycle and profitability of the firm. This means that as the cash conversion cycle increases it will lead to an increase in profitability of the firm, and managers can create a positive value for the shareholders by increasing the cash conversion cycle to a reasonable level; Secondly, there is a negative relationship between liquidity and profitability showing that as liquidity decreases, the profitability also increases; Thirdly, there exists a highly significant negative relationship between average collection period and profitability indicating that a decrease in the number of days a firm receives payment from sales affects the profitability of the firm positively; Fourthly, there is a highly significant positive relationship between average payment period and profitability. This implies that the longer a firm takes to pay its creditors, the more profitable it is.; and Fifthly, there exists a highly significant negative relationship between inventory turnover in days and profitability hinting that firms which maintain sufficiently low inventory levels reduce the cost of storing the inventory which results to higher profitability.
