=>The correct treatment for changes in working capital (net current assets) is

		Decreases in working capital are treated as cash outflows and are deducted for tax purposes over the life of the project.
		Working capital is not relevant for cash flow purposes or for taxation
		Increases in working capital are treated as cash outflows and are deducted for tax purposes over the life of the project.
		Increases in working capital are treated as cash outflows and do not affect tax.
		Decreases in working capital are treated as cash outflows and do not affect tax.

=>Which of the following is incorrect:

		The after tax cash flow of a non-cash expense in any period is E x T, where E equals non-cash expense and T equals the tax rate.
		The depreciation tax shield for a period is caclulated as D x T, where D = the amount of depreciation and T equals the tax rate.
		The tax savings from a Loss on Sale is equal to L x T, where L equals loss and T equals the tax rate.
		The after tax cash flow from cash revenue in any period is R x (1-T), where R equals revenue and T equals the tax rate.
		The tax savings from an investment allowance is equal to I x T A, where I equals the amount of eligible capital expenditure, A the rate of investment allowance and T equals the tax rate. =>When replacing Project A with Project B the incremental impact on the depreciation deduction is given by:
		Depreciation is not a cash flow therefore it can be ignored.
		Depreciation Of Project A minus Depreciation of Project B
		Depreciation Of Project A plus Depreciation of Project B
		Depreciation Of Project A divided by Depreciation of Project B.
		Depreciation of Project B only is deducted. Project A's depreciation can be ignored because it is being replaced.
