Off-Balance Sheet Arrangements We have no material off-balance sheet arrangements as defined in Item 303(a)(4)(ii) of Regulation S-K. Amounts invested in our foreign operations are translated into U.S. dollars at the exchange rates in effect at the balance sheet date. These undiscounted amounts are included in Accrued expenses and other current liabilities and Other non-current liabilities on the accompanying Consolidated Balance Sheets.

Our site in Malmö, Sweden, received the ISCC PLUS certification for its bio-based concentrates and ready-to-use formulations manufactured following the mass balance chain-of-custody approach.

While the vast majority of Avient sites are in urban and suburban areas, we recognize the critical importance of biodiversity not only for ecological balance, but also within the context of sustainable business practices.

Material selection can be a balancing act between over-engineering or underperformance.

The need to keep energy costs low is balanced by the desire to create a comfortable setting for attendees.

Shiny, transparent, saturated hues are disrupted by a deep opaque tone, while a highly de-saturated lime provides balance to this complex palette. 

Ultimately, choosing the right material for your application is a balance between sustainability goals, design requirements, end-to-end product costs, and performance targets.
