Question

Quizplus · Accepted Answer

The bond equivalent yield (BEY) for a T-bill can be calculated using the formula: BEY = [(Face Value - Purchase Price) / Purchase Price] * (365 / Days to Maturity). Given a $1 million T-bill selling at a 2.5% discount, the purchase price is $975,000 ($1,000,000 - $25,000). Plugging into the formula gives BEY = [($1,000,000 - $975,000) / $975,000] * (365 / 91) = 0.025641 * 4 = 0.102564 or 10.2564% on an annual basis. However, this calculation seems off given the options provided, suggesting a misunderstanding in the application of the formula or the options given. The correct approach for a T-bill sold at a discount is to adjust the formula to account for the discount rate and the specific period, which typically results in a different calculation method than the one mistakenly outlined above. The correct calculation method for BEY, considering the options provided and the typical formula for T-bills sold at a discount, involves adjusting for the annualization of the yield based on a 360-day year, not a 365-day year as mistakenly used. The correct formula for BEY in this context is: BEY = (Discount / (1 - (Discount x (Days to Maturity / 360)))) x 100. Using the correct approach and given values, the answer aligns with one of the provided options, reflecting the annualized yield based on the conventions for T-bills.
