Cash and Cash Equivalents

Cash equivalents are short-term, highly liquid investments that can be quickly converted to cash with minimal risk of value change. They provide safety and liquidity but typically offer lower returns than longer-term investments.

Characteristics of Cash Equivalents

  • Maturity: Generally one year or less
  • Liquidity: Easily converted to cash
  • Safety: Minimal price fluctuation
  • Return: Lower yields than longer-term investments

Types of Cash Equivalents

Treasury Bills (T-Bills)

T-Bills are short-term U.S. government securities considered the safest investments available.

FeatureDetails
IssuerU.S. Treasury
Maturities4, 8, 13, 17, 26, and 52 weeks
Minimum Purchase$100
InterestSold at discount; matures at par
Tax TreatmentFederal taxable; state/local EXEMPT

How T-Bills Work: If you buy a 52-week T-Bill with a $1,000 face value for $950, you receive $1,000 at maturity. Your return is the $50 discount.


Commercial Paper

Commercial paper is short-term, unsecured debt issued by corporations to fund short-term obligations like payroll and inventory.

FeatureDetails
IssuerCorporations with strong credit ratings
MaturitiesUp to 270 days
Minimum PurchaseTypically $100,000+
SecurityUnsecured (backed only by issuer's creditworthiness)

Why 270 Days? Commercial paper with maturities over 270 days must be registered with the SEC. By keeping maturities at 270 days or less, issuers avoid registration requirements.
