Suppose $1million is discounted over a full calendar year of 365 days using a bank discount yield of 5% and an assumed 360-day business year. What is the resulting acceptance (current) price?
Acceptance Price = Face Value (1-DTM*discount) 360 $949,305. 56 = $1,000,000(1-365*0.05) 360

Suppose you wanted to buy a T-bill with 85 days to maturity and a face value of $5,000,000. How much would you have to pay if the ask discount is 3.41%?
Ask Price = 5,000,000(1 - 85 * 0.0341) 360 Ask Price = $4,959,743.06
Suppose a T-bill has 45 days to maturity and an ask discount of 5%. What is the bond equivalent yield?
BEY = 365*0.05 360-45*0.05 BEY = 0.05101 (5.101%)

BEY = 365*discount 360-dtm*discount BEY= 365*0.0322 360-170*0.0322 BEY = 0.03315 (3.315%)
A T-bill has a face value of $1,000,000, a bid discount rate of 0.140%, and an ask discount rate of 0.130%. The T-bill matures in 240 days. What is the bid price? What is the ask price?
Bid Price = $1,000,000(1 - 240 * 0.00140) 360 Bid Price = $999,066.67 Ask Price = $1,000,000(1 - 240 * 0.00130) 360 Ask Price = $999,133.33

Suppose a banker's acceptance has a face value of $1 million that will be paid in 90 days. If the interest rate, quoted on a discount basis, is 5%, what is the current price of the acceptance?
Current Price = Face Value(1-DTM*discount) 360 987,500 = $1,000,000(1 - 90 * 0.05) 360
Suppose a banker's acceptance has a face value of $1 million that will be paid in 90 days. If the interest rate, quoted on a discount basis, is 5%, what is the discount aka the interest earned over the 90-day period until the acceptance matures?
Current Price = Face Value(1-DTM*discount) 360 987,500 = $1,000,000(1 - 90* 0.05) 360 Discount = Face Value-Current Price $12,500 = $1,000,000-$987,500
If you receive $1,000 today, what is the equivalent amount of money received in 3 years What formula do we use and what does each acronym mean?

If you need to calculate a STRIPS ask yield using its price, what would you do? Use the following info: N = 2M r = YTM/2 Maturity = 6 years Ask Price = $73.031 Face Value = $100 (it will always be 100)
YTM = 2[(Face Value)^1/2M - 1] [(STRIPS Price) = 2 [( 100 )^1/(2*6) - 1] [(73.031) STRIPS Ask Yield = 0.05307 (5.307%)
reinvestment risk is the risk that
a bond's future coupon payments may have to be invested at a rate lower than the bond's yield to maturity
The preferred habitat theory is
a compromise between market segmentation and maturity preference, where the market has different investors with different preferred maturities and can be induced to move to less preferred maturities by a higher interest rate
Treasury yield curve
a graph of treasury yields plotted against maturities
Bank discount basis
a method for quoting interest rates on money market instruments
Banker's acceptance
a postdated check on which a bank has guaranteed payment; commonly used to finance international trade transactions
For Treasury STRIPS, the number of periods is "a" and the interest rate is "b"
a. 2M (2*number of years until maturity) b. YTM/2
The formula used to calculate the acceptance price (current price) assumes a "a" day business year, with exactly "b" "c" day quarters because it made the calculation simpler and less subject to error.
a. 360 day business year b. 4 c. 90 day quarters
Medium credit quality corporate debt is denoted as "a" while high credit quality corporate debt is denoted as "b"
a. Triple B rated b. Double A rated
High yield bonds refers to corporate bond with
above average default risk
In the maturity preference theory, the preferred habitat is
always toward shorter maturities rather than longer maturities
An ask yield for a US Treasury STRIPS is
an Annual Percentage Return (APR)
The bond equivalent yield on a T-bill is also just
an Annual Percentage Return (APR)

an expected future interest rate implied by current interest rates (what you can expect in the future based on quotes today)
Fisher Hypothesis
assertion that the general level of nominal interest rates follows the general level of inflation
What are tax exempts
bonds issued by municipal governments that are exempt from federal income taxes and are often exempt from state income taxes too
If you intend to buy a T-bill, you must pay the (bid/ask) price
buyers pay the ask price
The market segmentation theory suggests that
debt markets are segmented by maturity, with the result that interest rates for various maturities are determined separately in each segment
Triple B rated bonds pay "higher/lower" interest rates compared to Double A rated bonds?
higher because they are more risky
Federal Funds rate
interest rate that banks charge each other for overnight loans of $1 million or more
Bellwether rate
interest rate that serves as a leader or as a leading indicator of future trends, e.g., interest rates as a bellwether of inflation
Real interest rates are
interest rates adjusted for the effect of inflation, calculated as nominal - inflation
Nominal interest rates are
interest rates as they are normally observed and quoted, with no adjustment for inflation

Expectations Theory
the term structure of interest rates is a reflection of financial market beliefs regarding future interest rates

A typical credit card may quote an APR of 18%. On closer inspection, you will find that the rate is actually 1.5% per month. What annual interest rate are you really paying on such a credit card? (AKA, what is the effective annual rate?)
1+EAR = (1+APR)^m m EAR = (1 + 0.18)^12 - 1 12 EAR = 0.1956 (19.56%)
Suppose the ask discount for a $1,000,000 T-bill that matures in 170 days, is 3.22%. 1. What is the ask price? 2. What is the discount? 3. What % will you earn on the $1mil investment considering its ask price? 4. What is the APR? 5. What is the EAR?
1. Ask Price = 1,000,000 (1 - 170 * 0.0322) 360 = $984,794 2. Discount = 1,000,000 - 984,794.44 = $15,206 3. % Earnings = 15,206 984,794 = 1.544% 4. APR = 365/170 = 2.147pds/yr = 1.544%*2.147pds/yr = 3.315% 5. EAR = (1 + 0.03315)^2.147 - 1 2.147 = 0.03344 (3.344%)
A money market instrument with 60 days to maturity has a quoted ask price of 99, meaning $99 per $100 face value. 1. What is the banker's discount yield? 2. What is the bond equivalent yield? 3. What is the effective annual return?
1. Current Price = 100(1 - 60 * y) 360 99 = 100(1 - 60 * y) 360 99 = 100(1-0.167y) 99 = 100 - 16.7y -100 -100 -1 = -16.7y -16.7 -16.7 Banker's Yield = 0.059 (6%) 2. BEY = 365*0.06 360-60*0.06 Bond Equivalent Yield = 0.06145 (6.145%) 3. EAR = 1- (1 + 0.06145)^365/60 365/60 Effective Annual Return = 0.06305 (6.305%)
