How and why does working capital affect the incremental cash flow estimation for a proposed large capital budgeting project?  Explain.

Several large projects require additional working capital.  This investment in additional working capital develops into part of the initial investment.  This investment is recovered in the last part of the project's life.  There may be some impulsive increase in current liabilities associated with a project however the change in net working capital, if any, is probable to be a positive value requiring an increase in the initial investment of that amount.
