The Language of Business Mathematics
- Canada Premium Bond (CPB)
-
A savings bond that is redeemable only during its anniversary month.
- Canada Savings Bond (CSB)
-
A savings bond that is redeemable at any time.
- compound interest GIC
-
A GIC that uses compound interest rates for which interest is periodically calculated and converted to the principal of the GIC for further compounding.
- compound interest savings bonds
-
Called C-bonds, these bonds annually convert the interest on the savings bond to principal.
- deflation
-
The overall downward price movement of products in an economy, which is measured by negative change in the consumer price index.
- escalator interest GIC
-
A GIC that uses compound interest rates that usually remain constant during each of a series of time intervals, always rising stepwise throughout the term of the investment with any accrued interest being converted to principal.
- inflation
-
The overall upward price movement of products in an economy, which is measured by positive change in the consumer price index.
- interest payout GIC
-
A GIC where the interest is periodically paid out to the investor, but it is never added to the principal of the GIC. Because the interest does not actually compound, in essence the concepts of simple interest are used.
- regular interest savings bonds
-
Called R-bonds, these bonds annually pay the interest to the owner of the bond and do not convert the interest to principal.
- savings bonds (SBs)
-
Long-term financial instruments with 10-year maturities issued only by the Canadian federal government to finance the long-term national debt.
- strip bond
-
A marketable bond that has been stripped of all interest payments.
The Formulas You Need to Know
Symbols Used
\(I\) = Interest payment amount
\(i\) = Periodic interest rate
\(n\) = number of pieces of data or variables
\(N\) = Number of compounding periods
\(PPD\) = Purchasing power of a dollar
\(PV\) = Principal or present value
Formulas Introduced
Formula 10.1 Periodic Interest Amount: \(I = PV × i\)
Formula 10.2 Purchasing Power of a Dollar (Compound Interest Method): \(PPD=\dfrac{\$ 1}{(1+i)^{N}} \times 100\)
