Overview of debt investments
Debt investments represent financial instruments that establish a creditor relationship between the investor and the issuing entity. In this arrangement, the investor lends funds to another party and expects to receive periodic interest payments and repayment of principal at maturity.
Unlike equity investments, debt investments do not provide ownership rights or control. Instead, they provide contractual cash flows, making them generally more predictable.
Common examples of debt investments include:
- Corporate bonds
- Government securities (e.g., treasuries)
- Notes or certificates meeting the debt security definition
ASC 320 applies to debt securities (including securitized loans that are securities), but excludes most trade receivables and non‑security loans.
Key characteristics of debt securities
Debt securities share several important characteristics that distinguish them from equity investments.
-
Fixed or determinable payments
Investors receive interest income based on a stated or effective interest rate. -
Maturity date
Debt securities have a specified date at which the principal is repaid. -
No ownership rights
Investors do not participate in the management or profits of the issuing entity. -
Priority over equity
In liquidation, debt holders are paid before equity holders.
Classification of debt investments
Under US GAAP, debt investments are classified into three categories:
- Trading securities
- Available-for-sale (AFS) securities
- Held-to-maturity (HTM) securities
Decision framework for classification
The classification of a debt investment depends on two key factors:
- Management’s intent
- Ability to hold the investment to maturity (for HTM only)
Core principle (ASC 320-10-25): Every debt security must be classified into one of three categories at acquisition based on management’s intent and ability. Classification cannot change after initial recognition except in rare circumstances (reclassifications trigger tainting rules).
Example: Classifying a corporate bond
Quality Corp purchases a $50,000 corporate bond. Management does not intend to sell it for short-term profit, and Quality Corp has both the intent and the financial ability to hold the bond until it matures in five years.
- Step 1: Is the intent short-term profit? No.
- Step 2: Does management have both intent and ability to hold to maturity? Yes.
- Classification: held-to-maturity (HTM)
- Measurement consequence: the bond is reported at amortized cost, and unrealized gains/losses are not recognized (only credit losses via the CECL allowance).
Answer: HTM; measured at amortized cost.
Measurement overview under US GAAP
All debt securities are initially recorded at their purchase price (fair value at acquisition), with transaction costs capitalized for AFS and HTM securities and expensed for trading securities.
Subsequent measurement depends on classification:
| Classification | Measurement | Unrealized gains/losses |
| Trading | Fair value | Net income |
| AFS | Fair value | OCI (noncredit portion); credit losses to income (ASC 326‑30) |
| HTM | Amortized cost | Not recognized (credit losses via CECL allowance, ASC 326) |
The next chapters walk through each classification - trading, HTM, and AFS - in detail, including how amortized cost and fair-value adjustments are calculated for each.
