Polymers are a class of organic materials that are generally produced by converting natural gas or crude oil derivatives into monomers, such as ethylene, propylene, and styrene. Amounts invested in our foreign operations are translated into U.S. dollars at the exchange rates in effect at the balance sheet date. The fair value of derivative financial instruments recognized in the Consolidated Balance Sheets as of December 31, 2023 and 2022 is as follows: (In millions) Balance Sheet Location 2023 2022 Cross Currency Swaps (Net Investment Hedge) Other non-current liabilities $ 199.1 $ 68.6 63 AVIENT CORPORATION ITEM 9.

Natural gas, electricity, fuel, logistics and raw material costs could cause volatility in our results. Natural gas and raw materials costs represent a substantial part of our manufacturing costs. Off-Balance Sheet Arrangements We have no material off-balance sheet arrangements as defined in Item 303(a)(4)(ii) of Regulation S-K.
