How does cash management help a firm maintain liquidity?

"Cash Management: Assuring Liquidity Cash is the lifeblood of business. Without it, a firm could not operate. An important duty of the financial manager is cash management , or making sure that enough cash is on hand to pay bills as they come due and to meet unexpected expenses. Businesses estimate their cash requirements for a specific period. Many companies keep a minimum cash balance to cover unexpected expenses or changes in projected cash flows. The financial manager arranges loans to cover any shortfalls. If the size and timing of cash inflows closely match the size and timing of cash outflows, the company needs to keep only a small amount of cash on hand. A company whose sales and receipts are fairly predictable and regular throughout the year needs less cash than a company with a seasonal pattern of sales and receipts. A toy company, for instance, whose sales are concentrated in the fall, spends a great deal of cash during the spring and summer to build inventory. It has excess cash during the winter and early spring, when it collects on sales from its peak selling season. Because cash held in checking accounts earns little, if any, interest, the financial manager tries to keep cash balances low and to invest the surplus cash. Surpluses are invested temporarily in marketable securities , short-term investments that are easily converted into cash. The financial manager looks for low-risk investments that offer high returns. Three of the most popular marketable securities are Treasury bills, certificates of deposit, and commercial paper. ( Commercial paper is unsecured short-term debt—an IOU—issued by a financially strong corporation.) Today’s financial managers have new tools to help them find the best short-term investments, such as online trading platforms that save time and provide access to more types of investments. These have been especially useful for smaller companies who don’t have large finance staffs. Companies with overseas operations face even greater cash management challenges. Developing the systems for international cash management may sound simple in theory, but in practice it’s extremely complex. In addition to dealing with multiple foreign currencies, treasurers must understand and follow banking practices and regulatory and tax requirements in each country. Regulations may impede their ability to move funds freely across borders. Also, issuing a standard set of procedures for every office may not work because local business practices differ from country to country. In addition, local managers may resist the shift to a centralized structure because they don’t want to give up control of cash generated by their units. Corporate financial managers must be sensitive to and aware of local customs and adapt the centralization strategy accordingly. In addition to seeking the right balance between cash and marketable securities, the financial manager tries to shorten the time between the purchase of inventory or services (cash outflows) and the collection of cash from sales (cash inflows). The three key strategies are to collect money owed to the firm (accounts receivable) as quickly as possible, to pay money owed to others (accounts payable) as late as possible without damaging the firm’s credit reputation, and to minimize the funds tied up in inventory."
