Cash equivalents are short-term investments so liquid and stable that accountants group them with actual cash on the balance sheet. To qualify, an instrument has to convert quickly into a known amount of money and carry almost no risk of losing value along the way. In practice, that limits the category to things the company bought with about 90 days or less left until maturity. The combined “Cash and Cash Equivalents” line that results is the most-watched signal of whether a business can meet its obligations right now.
The Two-Part Test
Both U.S. GAAP and IFRS apply the same two requirements. First, the investment must be readily convertible into a known amount of cash. That means an active market exists and the holder can sell without accepting a meaningful discount. Second, the investment must carry an insignificant risk of changes in value, so the principal is protected from market swings.1IFRS Foundation. IAS 7 Statement of Cash Flows
The practical way accountants operationalize the second requirement is by looking at maturity. Under GAAP, only investments with an original maturity of three months or less generally qualify. IAS 7 uses slightly softer language, saying an investment “normally qualifies as a cash equivalent only when it has a short maturity of, say, three months or less from the date of acquisition.”1IFRS Foundation. IAS 7 Statement of Cash Flows In practice, both frameworks land at 90 days.
What “Original Maturity” Actually Means
This is the detail readers get wrong most often. “Original maturity” refers to the remaining term at the moment the reporting company acquires the instrument, not the term when it was first issued. A three-year Treasury note purchased on the secondary market with 60 days left qualifies, because the holder’s exposure to rate shifts over those 60 days is negligible. A newly issued six-month CD does not qualify, because the holder is exposed to six months of possible rate changes from the day of purchase. And a 12-month CD that happens to have 45 days remaining on the balance sheet date does not become a cash equivalent retroactively. The test always looks back to the day the company first bought or opened the instrument.
What Counts as a Cash Equivalent
Treasury Bills
U.S. Treasury bills are the textbook example. They are backed by the full faith and credit of the federal government, carry effectively zero default risk, and come in 4-, 8-, 13-, 17-, and 26-week maturities. The 4-, 8-, and 13-week bills fall inside the 90-day window automatically. As of early February 2026, the 3-month T-bill yields roughly 3.6% to 3.7% on an annualized basis.2U.S. Department of the Treasury. Daily Treasury Bill Rates
Commercial Paper
Commercial paper is an unsecured promissory note issued by large corporations to fund short-term needs. To count as a cash equivalent, the paper must have an original maturity of 90 days or less and come from a highly rated issuer. Top short-term ratings such as Moody’s P-1 or S&P’s A-1 signal extremely low default risk. Historically, the 180-day default probability for the highest-rated commercial paper has run around 0.01%, which is why analysts are comfortable treating it as near-cash when the credit thresholds are met.
Money Market Funds
Money market funds pool investor money into short-term government securities, commercial paper, and other low-risk debt. Government and retail money market funds still target a stable net asset value of $1.00 per share, which satisfies the insignificant-risk test. Institutional prime and municipal funds, however, are required to use a floating NAV under SEC reforms, so their share price can move slightly.3eCFR. 17 CFR 270.2a-7 – Money Market Funds Whether a floating-NAV fund still qualifies as a cash equivalent depends on the company’s own policy and how much the price actually moves. Government funds with a fixed $1.00 NAV are the easiest to classify.4Office of the Comptroller of the Currency. Money Market Funds: Compliance With SEC Money Market Fund Rules
Short-Term Certificates of Deposit
A CD qualifies only if its term at the time the company acquires it is 90 days or less. A 60-day CD fits. A 12-month CD does not, no matter how close it eventually gets to maturity.
What Doesn’t Qualify
Several categories look liquid but fail one of the two tests.
- Equity investments. Common stock, preferred stock, and equity ETFs move in price every day. That volatility violates the insignificant-risk requirement, no matter how large or blue-chip the issuer is.
- Restricted cash. Funds held in escrow, pledged as loan collateral, or earmarked by a court order are not freely available, so they fail the readily-convertible test. Restricted cash is reported separately on the balance sheet.
- Corporate and municipal bonds. Even investment-grade bonds usually carry original maturities measured in years. A five-year municipal bond purchased with two months remaining could technically qualify under the original-maturity-to-the-holder rule, but in practice most companies limit this treatment to Treasuries and similarly risk-free instruments because bonds carry credit risk that Treasuries do not.
- Most cryptocurrency. Beginning with fiscal years after December 15, 2024, FASB ASU 2023-08 requires companies to measure qualifying crypto assets at fair value each reporting period, with gains and losses flowing through net income. That treatment is fundamentally different from how cash equivalents work, and the price swings common in tokens like Bitcoin or Ether make the insignificant-risk requirement impossible to satisfy.5Financial Accounting Standards Board.

Where Stablecoins Currently Sit
Dollar-pegged stablecoins are the one live edge case worth knowing about. In April 2025, the SEC’s Division of Corporation Finance issued a staff statement indicating that holders of certain dollar-pegged stablecoins could classify them as cash equivalents if the coins have a guaranteed redemption mechanism and sufficient value stability.6SEC.gov. Statement on Stablecoins Separately, the SEC rescinded Staff Accounting Bulletin 121, which had required entities safeguarding crypto assets for others to recognize a liability and corresponding asset on their balance sheets.7SEC.gov. Staff Accounting Bulletin No. 122 Neither step created a blanket rule. Whether a particular stablecoin qualifies still turns on redemption terms, issuer backing, and the company’s own accounting policy, and any company that classifies stablecoins this way should expect auditor scrutiny.
How Cash Equivalents Show Up on Financial Statements
Balance Sheet
Cash equivalents are combined with physical currency and bank balances into a single line item called “Cash and Cash Equivalents,” reported at the top of current assets. Analysts plug this number into liquidity ratios. The strictest is the cash ratio, which divides cash and cash equivalents by total current liabilities to show what share of short-term obligations the company could cover immediately without selling inventory or collecting receivables.
Statement of Cash Flows
The cash flow statement explains why the Cash and Cash Equivalents balance changed from the start to the end of the period. Because cash equivalents fall inside the definition of “cash” for this statement, buying or selling a qualifying instrument does not appear as a separate investing activity.8SEC.gov. What Is a Statement of Cash Flows? It’s like moving money between two checking accounts at the same bank. The total is unchanged, so there is nothing to report.
Disclosure Notes
Under GAAP, companies must state in the notes which types of short-term investments they treat as cash equivalents. That’s where an investor can check whether a company is drawing the line in a reasonable place or classifying something aggressive.
The Cost of Holding Cash Equivalents
Cash equivalents are the safest place to park short-term funds, but safe is not the same as free.
The first drag is inflation. A company holding $10 million in T-bills earning 3.6% while inflation runs at 3% is barely staying even in real terms. When inflation outpaces short-term yields, the purchasing power of the cash-equivalents balance actively shrinks.
The second is opportunity cost. As of early 2026, 3-month T-bills yield roughly 3.6% annualized while 10-year Treasuries yield over 4%.2U.S. Department of the Treasury. Daily Treasury Bill Rates Corporate bonds and equities have historically returned more over longer horizons. Sitting on a large cash-equivalents position can be rational ahead of an acquisition or during an uncertain market, but the price is forgone return. When the balance climbs quarter after quarter with no clear strategic purpose, analysts tend to read that as a yellow flag rather than reassurance.
