Working capital management involves administering current assets like cash and inventory to fund day-to-day operations. It aims to balance liquidity against returns. There are conservative, moderate, and aggressive working capital policies that respectively carry more cash, less cash, and impact liquidity and returns differently. Firms must determine optimal current asset levels that minimize carrying and shortage costs. Permanent working capital funds fixed needs while temporary funds fluctuating needs like the operating cycle. Factors like the business, production, and economic environment influence working capital composition.
