> Effective January 2023, Intel increased the estimated useful life of certain production machinery and equipment from five years to eight years. When compared to the estimated useful life in place as of the end of 2022, Intel expects total depreciation expense in 2023 to be reduced by $4.2 billion. Intel expects this change will result in an approximately $2.5 billion increase to gross margin, a $400 million decrease in R&D expenses and a $1.3 billion decrease in ending inventory values.
