How Subtracting Net Debt Leads to Equity Value—and the Exceptions
Net debt is interest-bearing debt minus eligible cash. Worked examples explain restricted cash, leases, and noncontrolling interests when bridging operating value to equity value.
In a simple structure, subtracting net debt from operating value leads to shareholders’ equity value. Net debt generally means interest-bearing debt minus the cash eligible for that calculation, but its scope can differ by company. Other claims and nonoperating assets require additional adjustments.
Distinguish interest-bearing debt from total liabilities
Do not use total balance-sheet liabilities directly in net debt. Accounts payable and contract liabilities arise from operations and may already be reflected in operating working capital or future cash flows. Build interest-bearing debt from financing items such as short-term borrowings, long-term borrowings, and bonds. Record whether lease liabilities are included and how the corresponding operating costs and cash flows are treated. Moving maturing borrowings into current liabilities does not increase total borrowings, so compare combined short- and long-term amounts on a consistent basis.
Not all cash can be added in the same way
Cash pledged as collateral or restricted by contract differs from cash immediately available for distribution to shareholders. Review access and purpose for cash in overseas subsidiaries and balances needed to maintain operations as well. If cash-related income is excluded from operating value and cash itself is added separately, do not also include that income in perpetual cash flow. Set consistent boundaries: if operating cash is already included in working capital, for example, do not add all cash again as a nonoperating asset.
Connect the reason for lower net debt to value
The implications differ depending on whether debt was repaid with operating cash, new equity, or proceeds from selling core assets. Assuming shareholders’ value rises by the amount of a debt reduction can overlook lower operating value or dilution. Paying down debt with cash can reduce both by the same amount and leave net debt unchanged. Before arriving at common-equity value, complete the valuation bridge by reviewing noncontrolling interests, priority claims, separately valued equity holdings, and other items.
Worked example
Hypothetical example: Operating value of KRW 150 billion, interest-bearing debt of KRW 50 billion, and cash eligible to be added separately of KRW 18 billion imply net debt of KRW 32 billion and equity value of KRW 118 billion. Repaying KRW 10 billion of debt with KRW 10 billion of cash leaves debt of KRW 40 billion and cash of KRW 8 billion, so net debt remains KRW 32 billion. With other conditions unchanged and no repayment costs, that transaction alone does not increase calculated equity value.
What to check
- Have you checked the components of interest-bearing debt rather than total liabilities?
- Is any cash being deducted restricted or needed for operations?
- Have you avoided valuing both cash income and the cash asset twice?
- Did asset sales or share-count increases accompany the debt reduction?
