Debt security investment

Working definition

An investor's creditor interest represented by a debt instrument within the applicable debt-security accounting scope.

Also calledDebt investment · Investor-held debt security

A debt security investment is the holder's contractual right to receive cash from an issuer. Common examples include corporate bonds, municipal securities, commercial paper, and U.S. Treasury securities. ASC 320-10-15-2 describes the Topic's entity scope, while the Codification glossary gives the specific debt-security definition used in that guidance.

Read the contract from the holder's side

Suppose an entity buys a $500,000 bond that pays 5 percent annual interest in two equal installments. The holder expects two $12,500 cash receipts each year and $500,000 at maturity. Those cash flows are an asset to the holder. They are a liability to the issuer. The shared contract does not make the two accounting records mirror images.

The holder must establish debt-security scope and classification. It may also need an effective-interest schedule, a credit-loss analysis, fair-value measurement, and sale or transfer controls. The issuer instead applies the guidance for its own debt obligation. Different transaction costs, elections, credit rules, and reporting purposes can produce different carrying amounts.

Do not confuse a debt instrument with every receivable

Some rights to receive cash are not securities. A trade receivable or a loan that does not meet the security definition can follow another Topic. Preserve the executed agreement, security identifier, principal and coupon terms, purchase date, settlement evidence, and scope conclusion before calculating interest. The contract supplies the cash-flow map; the holder's accounting route supplies the measurement rules.
