Some companies present this subtotal on the face of the balance sheet, often under a heading such as investments and advances or investments and other receivables. In XBRL filings the combined figure is tagged LongTermInvestmentsAndReceivablesNet. When a company reports the parts on separate lines, the total can be built from LongTermInvestments and LongTermAccountsNotesAndLoansReceivableNetNoncurrent, along with any separately tagged equity-method or related-party balances.
Regulation S-X splits the underlying items across captions. Rule 5-02.12 covers other investments and requires the basis of measurement to be stated, along with the alternative of cost or market value. Rule 5-02.11 covers noncurrent indebtedness of related parties, such as loans to affiliates or joint ventures, and Rule 5-02.10 covers securities of related parties. The accounting follows the underlying standards: ASC 320 and ASC 321 for securities, ASC 323 for equity-method stakes, and ASC 310 and ASC 326 for receivables and their credit-loss allowances.
Because the subtotal mixes very different assets, analysts usually look through it to the components. Marketable debt securities may be close to cash. Equity-method investments reflect strategic stakes whose carrying amount can differ greatly from market value. Long-term receivables can be customer financing, which carries credit risk, or loans to related parties, which may deserve a closer look. A large and growing balance relative to total assets means more of the company's value rests on claims against other entities rather than on its own operations.
