For the years ended December 31, 2021 and 2020, approximately 99.0% of the Company’s revenue is subject to point-in-time recognition for single-use (disposable) products and capital equipment sales. Sale of extended warranties on capital equipment represents less than 1.0% of the Company’s revenue. In addition, more than 98.0% of the Company’s total revenue is derived from the sale of single-use (disposable) products; therefore, the Company did not include disaggregated revenue data to present the amounts attributed to capital equipment, associated warranties, and miscellaneous revenue separately.
