Working capital management and profitability: Cash threshold effects in Vietnam’s transportation sector

Working capital management plays a pivotal role in enhancing the operational efficiency of firms and their ultimate profitability. Therefore, the purpose of this study was to examine the trends in working capital management and its impact on the financial performance of listed manufacturing firms on the Johannesburg Securities Exchange (JSE). A panel data methodology was used with different regression estimators to analyze this relationship based on an unbalanced panel of 69 manufacturing firms listed during the period 2007–2016.
The findings revealed that the average collection period and the average payment period are negative and statistically significant for profitability, implying that firms which efficiently manage their accounts receivable and those that pay their creditors on time perform better than those that do not. Additionally, a positive statistically significant relationship between the number of days in inventory and profitability was supported suggesting that firms which stock-up and maintain their inventory levels suffer less from stock-outs and avoid challenges of securing financing when needed. This increases their operational efficiency and ensures profitability in the long run. It could not be ascertained whether a shorter or longer cash conversion cycle enhances firm profitability, since findings to support this premise were weak. However, it was observed that manufacturing firms are on average, carrying lot of debt in their capital structures.
The present study contributes to existing literature by presenting one of the very recent findings on this topic while simultaneously testing the validity of recent local and international methodologies, in order to inform policy change.

The Working Capital Management (WCM) has an important role for the firm’s success or failure, because it directly affects the overall business health of the firm. This study examined the impact of WCM on profitability and shareholders’ wealth using 50 companies listed in different sectors on the Colombo Stock Exchange (CSE) for the period from 2010 to 2015. This sample represents 47% of the selected sectors of CSE. The profitability of the company is measured using gross operating profit (GOP) and shareholders wealth measured by Tobin’s Q (TQ) ratio. The WCM is measured using five independent variables namely stock holding period (SHP), debtors’ collection period (DCP), creditors’ settlement period (CSP), cash conversion circle (CCC) and current assets ratio (CAR). Further, three additional variables such as firm size (SIZE), leverage (LEV) and earning yield (EY) are employed as controlling variables to capture the impact of other performance of the companies.
The data were analyzed using ordinary least square (OLS) and panel data regression models. These regression models reveal that there is a significant negative relationship between CCC and dependent variables (GOP & TQ). Further, this relationship has been confirmed by the major components of CCC such as SHP, DCP. Firm size also positively and significantly effects on the firm GOP while negatively effects on the TQ. Further, they revealed that there is a significant positive relationship between LEV and TQ. The study finds that the shareholders’ wealth and profitability can be increased through the efficiency of WCM.

Liquidity is a firm’s ability to pay its current obligations as they come due and thus remain in business in the short run, which reflects the ease with which assets can be converted to cash. The objective of working capital management (WCM) is to minimize the cost of maintaining liquidity while guarding against the risk of insolvency, working capital policy applies to short-term decisions, and capital structure finance applies to long-term decisions.
Several studies have been conducted on the impact of WCM on cash holding levels. The impact of WCM on liquidity and cash holding levels is analyzed in this study. The study also makes a comparison between large- and small-scale firms. Panel data for 62 Jordanian industrial firms covering an eleven-year period (2006–2016) have been analyzed. The descriptive analysis indicates that large firms hold more cash than small firms, as well as more debt, cash flow and growth.
The findings of the data set indicate that WCM, as a variable (working capital net of cash), is a strong predictor of firm cash holding levels. When a firm has several cash substitutes, it will maintain low cash levels. The separate analysis shows that there are significant differences between small- and large-scale firms for determinates related to cash holding levels. Firm size and cash flow ratios were strong predictors of cash holding levels for both samples.
