| Change in accounting estimate, description | After upgrading its Order Management System (“OMS”) in March 2025, the Company transitioned to a curve-based model that aligns with the methodology used to estimate returns for its Retail channel. The new model is expected to provide a more accurate reflection of customer return behavior. Additionally, in the first quarter of 2025, the Company reduced the allowable return window for Direct and Retail sales from 90 to 60 days, which also impacted the estimate of expected returns. The Company further revised its methodology for estimating the Retail sales returns reserve in the third quarter of 2025. The Company no longer includes an exchange assumption to better align the reserve with the data provided under its new OMS. | |||||
