Esquire Clothing is a manufacturer of designer suits. The cost of each suit is the sum of three variable costs ( direct material costs, direct manufacturing labor costs, and manufacturing overhead costs) and one fixed- cost category ( manufacturing overhead costs). Variable manufacturing overhead cost is allocated to each suit on the basis of budgeted direct manufacturing labor- hours per suit. For June 2012 each suit is budgeted to take four labor- hours. Budgeted variable manufacturing overhead cost per labor- hour is $ 12. The budgeted number of suits to be manufactured in June 2012 is 1,040.
Actual variable manufacturing costs in June 2012 were $ 52,200 for 1,095 suits started and completed. There was no beginning or ending inventories of suits. Actual direct manufacturing labor-hours for June were 4,566.

Risk is the risk of a decline in a bond's value due to an increase in interest rates. this risk is higher on bonds that have long maturities than on bonds that will mature in the near future. risk is the risk that a decline in interest rates will lead to a decline in income from a bond portfolio. this risk is obviously high on callable bonds. it is also high on short-term bonds because the shorter the bond's maturity, the fewer the years before the relatively high old-coupon bonds will be replaced with new low-coupon issues. which type of risk is more relevant to an investor depends on the investor's , which is the period of time an investor plans to hold a particular investment. longer maturity bonds have high risk but low risk, while higher coupon bonds have a higher level of risk and a lower level of risk. to account for the effects related to both a bond's maturity and coupon, many analysts focus on a measure called , which is the weighted average of the time it takes to receive each of the bond's cash flows. conceptual question: which of the following bonds would have the largest duration? a)10year-zero coupon bonds b)10year-7% annual coupon bonds c)10year-3% annual coupon bonds d)5year-3% annual coupon bonds e)3year-7% annual coupon bonds
