4. (9 points) LifeCo wants to modify the design of its Equity Linked GIC product to reduce
the impact of a large decline in the stock market just before maturity. LifeCo believes
that these modifications should be done in such a way that the participation rate is as high
as possible and the profit margin remains the same.
The Company is also concerned about the cost of purchasing call options for the Equity
Linked GICs and is considering applying the dynamic hedging program it developed for
its Variable Annuities.
(a) Compare the options embedded in LifeCo’s Equity Linked GIC and Variable
Annuities.
(b) Recommend potential changes to the Equity Linked GIC product that would meet
LifeCo’s goals for the redesigned product.
(c) Describe the process used to evaluate the cost and efficiency of dynamic hedging.
(d) Evaluate LifeCo’s Variable Annuity dynamic hedging program as an alternative
to purchasing call options for its Equity Linked GIC product.
(e) Contrast the hedging of Equity Linked GICs as a stand-alone product to that of an
investment option of a Variable Universal Life product.
