Paragraphs:
Our net sales to significant customers as a percentage of total net sales were as follows:
We sell parts to these three transportation customers for certain vehicle platforms under purchase agreements that have no volume commitments and are subject to purchase orders issued from time to time.
No other customer accounted for 10% or more of total net sales during these periods. We continue to focus on broadening our customer base to diversify our end market exposure.
Changes in the level of our customers' orders have, in the past, had a significant impact on our operating results. If a major customer reduces the amount of business it does with us, or substantially changes the terms of that business, there could be an adverse impact on our operating results
