In our previous lecture, we saw that firms need not only long-term, but also short-term investments
These, in general, are referred to as net working capital:
Firms may also present seasonal sales patterns:
Question: how does a company manage its short-term needs within the year?
Overall, it seems that both Sales and Net Working Capital are trending upwards
Looking at the specifics of Arezzo’s working capital accounts, it seems it is being fueled mainly by Inventories, although Receivables have also increased significantly
Payables have substantially increased to sustain the firm’s growth. However, overall net capital needs have increased.
How to finance the remaining part?
In the next slides, we’ll study a step-by-step guide in short-term financing, following (Berk and DeMarzo 2019)
The first step in short-term financial planning is to forecast the company’s future cash flows
Within short-term financing planning, we are interested in analyzing the types of cash surpluses or deficits that are temporary and, therefore, short-term in nature
Typically, firmsrequire short-term financing for three reasons:
When sales are concentrated during a few months, sources and uses of cash are also likely to be seasonal.
The introduction of seasonal sales creates some dramatic swings in short-term cash flows:
While Cost of Goods Sold generally fluctuates proportionally with sales, other costs (such as administrative overhead and depreciation) do not, leading to large changes in the firm’s net income by quarter
Net working capital changes are more pronounced
Seasonal sales create large short-term cash flow deficits and surpluses: because of this, a firm may opt to invest surpluses in short-term investment options and use it during downturns
Negative Cash-Flow Shocks
Occasionally, a company will encounter circumstances in which cash flows are temporarily negative for an unexpected reason (e.g, higher costs, legal actions, widespread events, such as COVID-19, among others)
Such unexpected hits in the firm’s cash flow expectations might induce to an increase in financing needs
Example: what happened to delivery food chains during the onset of the pandemic in Brazil?
Positive Cash-Flow Shocks
Increases in firm’s expected sales can leader to increases in short-term financing needs. Going back to the example that we saw, ARZZ’s growth in sales was accompained by a surge in working capital needs!
A firm may have a temporary deficit before it actually reaps out the benefitis of positive cash-flow shocks (e.g, Marketing investments)

On the one hand, there is an opportunity cost of holding cash in accounts that pay little or no interest
On the other hand, firms also face high transaction costs if they need to negotiate a loan on short notice to cover a cash shortfall
Short-term needs should be financed with Short-term debt
Long-term needs should be financed with Long-term sources of funds
We saw that we can distinguish permanent and short-term working capital needs. The permanent portion of working capital]{.blue} is the amount that a firm must keep invested in its shortterm assets to support its continuing operations.
Because this investment in working capital is required so long as the firm remains in business
The matching principle indicates that the firm should finance this permanent investment in working capital with long-term sources of funds
In general, such sources have lower transaction costs than short-term sources of funds, which would have to be replaced more often.
Example: after forecasting permanent working capital needs, if funding using short-term sourcers (say, 1 year), firms are exposed to interest rate risk – in other words, you may have to refinance at a higher rate in the future! During, COVID-19, interest rate risk made smaller firms to shut-down its operations
Another portion of a firm’s investment in its accounts receivable and inventory is temporary and results from seasonal fluctuations in the firm’s business or unanticipated shocks
This temporary working capital need is the difference between the actual level of investment in short-term assets and the permanent working capital investment. Following the Matching Principle, it should be financed with short-term sources!
Using our previous example, we can use the minimum net working capital of a given quarter and fix it as our permanent component (\(X-\$2,125\))

What if we depart from the Matching Principle whenever financing firm’s activity? An Aggresive Policy is the case if we financed permanent working capital needs with short-term debt:
When firms can benefit from this policy? As short-term debt is less sensitive to the firm’s credit quality than long-term debt, firms can benefit from it whenever market imperfects are more acute
Furthermore, when the yield curve is upward sloping, the interest rate on short-term debt is lower than the rate on long-term debt
However, shareholders incur in funding risk, which is the risk of incurring financial distress costs if firm is not able to refinance its debt in a timely manner or at a reasonable rate
Alternatively, a firm could finance its short-term needs with long-term debt, a practice known as a Conservative Financing policy: use long-term sources of funds to finance its fixed assets, permanent working capital, and some of its seasonal needs
Whenever implementing such policy, there will be periods where there is excess cash - i.e, those periods when the firm requires little or no investment in temporary working capital
While such policy significantly reduces funding risks, it has its drawbacks:
