Commitments and Contingencies

Commitments and Contingencies

Management and our legal counsel periodically review the probable outcome of pending proceedings and the costs reasonably expected to be incurred. We accrue for these costs when it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. In the opinion of management, any ultimate cost to us in excess of amounts accrued will not materially affect our condensed consolidated financial position, results of operations or cash flows.
