ABSTRACT
This study investigated the relationship between working capital management
measured by account receivable period (ACRP), inventory period (INVP), cash
conversion cycle (CCC) and sales Growth (SG) and profitability performance
measured by returns on assets (ROA). The study utilized secondary data obtained
from the annual financial statements of Nigerian Manufacturing companies listed
on the Nigerian Stock Exchange (NSE) for period 2008 – 2012. Multiple
regression model were adopted for testing all the hypotheses and the study result
reveals that there was a negative significant relationship between the account
receivable period and profitability of the Nigerian Manufacturing companies. It
also reveals that the profit is significantly influenced by the number of days
inventory were held (INVP) and that the profitability performance negatively and
significantly related to the cash conversion cycle (CCC). These results suggest that
effective policies must be formulated for the individual components of working
capital. Furthermore, efficient management and financing of working capital
(current assets and liabilities) can increase the operating profitability of
manufacturing firms
