Can someone help me with the steps on working the following question? Thanks in advance

Tax Planning with Stock Options

ABC, Inc. wishes to provide stock options its CEO, Joe.In order to make ABC indifferent between ISOs and NQOs, assume that ABC grants some number of ISOs (or NQOs) such that the present value (as of the grant date) of ABCs expected after-tax cost is equivalent to $20,000. ABC discounts after-tax cash flows at 6%. The following timeline indicates the duration between key events and expected future stock values at those dates.

	Grant Date	Exercise Date	Sale Date
	1 year	1 year
	$5.00	$10.00	$12.00

That is, the stock is worth $5 per share at the grant date. The exercise price is also $5. The stock is expected to be worth $10.00 one year later when the options are exercised and $12.00 two years later when Joe will sell the stock.

(a) How many ISOs or NQOs would ABC grant if t_c = 10%? What if t_c = 35%?

NQOs

(b) Suppose Joe faces tax rates of tp= 40% and t_cg= 20%. His after-tax discount rate is 6%. Using the numbers of granted options that you computed above, what is the present value of Joes after-tax cash flows over the two year period?

(c) Explain how your answers to parts (a) and (b) relate to multilateral tax planning.
