Free cash flow is a non-GAAP financial measure defined as operating cash flow less capital expenditures. We consider free cash flow to be a liquidity measure which provides useful information to management and investors about the amount of cash generated by the business after our capital expenditures, which can then be used for strategic opportunities including, among others, investing in Microsemi's business, making strategic acquisitions, and strengthening the balance sheet. Management uses free cash flow as a supplemental measure to the net change in cash and cash equivalents as presented in Microsemi's consolidated statements of cash flows prepared in accordance with GAAP which incorporates all cash movements during the period.

Guidance is provided only on a non-GAAP basis due to the inherent difficulty of forecasting the timing or amount of certain items that have been excluded from the forward-looking non-GAAP measures, and a reconciliation to the comparable GAAP guidance has not been provided because certain factors that are materially significant to Microsemi's ability to estimate the excluded items are not accessible or estimable on a forward-looking basis.
