Additional impacts included higher cost of other materials and warranty costs as well as lower manufacturing productivity. This was partially offset by the impact of higher selling prices across all channels. Total operating expense for the full year was $238.8 million compared to $167.2 million for the full year 2021, representing an increase of 42.8%.
