Accretion of discount is a financial concept referring to the increase in the value of a discounted instrument, such as a bond, as its maturity date approaches. This process entails gradually accounting for the difference between the purchase price and the face value of the instrument over time.
Understanding Discounted Instruments
What Are Discounted Instruments?
Discounted instruments are securities sold at a price lower than their face or par value. Common examples include zero-coupon bonds and treasury bills. These instruments do not pay periodic interest but are instead issued at a discount and redeemed at face value upon maturity.
Example of a Discounted Bond
Consider a zero-coupon bond with a face value of $1,000 issued at $900. The $100 difference between the purchase price and the face value represents the discount.
Calculation of Accretion of Discount
Accretion Calculation Methods
There are multiple methods to calculate the accretion of discount, including the straight-line method and the effective interest method.
Straight-Line Method
In the straight-line method, the discount is evenly apportioned over the life of the bond.
Effective Interest Method
The effective interest method, often preferred for its accuracy, calculates accretion based on the instrument’s yield to maturity (YTM). The formula for the bond’s carrying amount at any given time is:
where \( C_t \) is the carrying amount at time \( t \) and \( r \) is the effective interest rate.
Significance of Accretion of Discount
Impact on Financial Statements
Accretion of discount is crucial for accurate financial reporting. It ensures that the bond’s carrying value increases over time, reflecting its true redemption value at maturity. This affects both the balance sheet and income statement of the holder.
Tax Considerations
Tax laws often require the recognition of accreted interest as taxable income, even though the investor does not actually receive the interest until maturity.
Historical Context
The concept of accretion can be traced back to early bond markets. The use of discounted instruments became more prevalent in the 20th century, with governments and corporations issuing zero-coupon bonds, especially during periods of economic instability.

Summary
Accretion of discount is a pivotal concept in finance, ensuring that the value of discounted instruments is accurately reflected over their life span. Understanding its calculation methods and significance can provide insight into investment valuation and financial reporting. Through proper accretion, discounted instruments present a true picture of their potential return as they approach maturity.
