We have historically invested approximately 6% to 7% of annual revenues on R&D to mitigate this risk. However, many of our competitors have dedicated more resources and capabilities to R&D, including committing more engineers and capital expenditures, to develop and design new products that may enter the market sooner or with more penetration.
