Working capital management in retail
Dibon, Michael ; Čornanič, Aleš (advisor) ; Novák, Jiří (referee)
This master thesis is focused on operating working capital and its implication towards corporate performance in the retail industry in a relevant business framework that takes into account structural changes in the industry. Our results suggest that there is a negative relationship between cash conversion cycle and corporate performance. Therefore, the management of retail companies should focus on shortening the cash conversion cycle to create value. However, in the apparel retail industry, companies with exceptionally long cash conversion cycles are better off keeping working capital investments high as those companies generate on the WC higher profitability than are the opportunity costs for this allocated capital. Finally, we have not found enough evidence to conclude that investment strategies based on the cash conversion cycle are able to generate alpha. However, there seems to be a sign of persistence for value-weighted portfolios. JEL Classification G31, G32 Keywords Working capital, Working capital management, Cash Conversion Cycle, Retail Author's e-mail michael.dibon@gmail.com Supervisor's e-mail ales.cornanic@gmail.com

Accounting-based credit scoring models - The Altman Z-score
Dibon, Michael ; Čornanič, Aleš (advisor) ; Kukačka, Jiří (referee)
This Bachelor thesis is focused on accounting-based credit scoring models, predominantly on Altman (1968) Z-score. We examine the relevance of the Z-score model on European publicly traded companies over the period 2012 - 2017. Moreover, we analyze whether it is important to calibrate original models as well as we test the performance of models given different misclassification costs. Our results suggest that Altman original Z-score model is still, after 50 years of existence, relevant in the European after-crisis environment. Further, we found evidence that re-estimation of the model is unnecessary and could even cause harm to model performance. Finally, the performance of models seems to be stable given not equal misclassification costs, as the more accurate models from ROC analysis reported better results in an economic test. Keywords Z-score, accounting-based models, credit score, Altman, financial ratios, bankruptcy, ROC, Europe
