Revenue from intangible assets is tied to underlying patent protected sales of DPP-IV products of various licensees. Such revenue is earned from sales occurring primarily in the United States and Europe; however, we do not have the ability to disaggregate such revenue from licensees based on the geography of the underlying sales as this information may not be provided to us by marketers. Individual licensees exceeding 10% or more of revenue from intangible royalty assets accounted for 90%, 86% and 97% of revenues from intangible royalty assets in 2022, 2021 and 2020, respectively.
