“on an aggregate basis, we estimate this will decrease full-year 2025 operating income by approximately $400 million for the assets on our balance sheet as of December 31, 2024.”

In context

“e rates based on current rates, which we expect to be a headwind of approximately $2.1 billion in Q1 year over year, or 150 basis points. As a reminder, global currencies can fluctuate during the quarter, and just as we saw in Q4 with the strengthening of the dollar versus most other currencies. Second, a reminder that we are comping the impact of last year's leap year. The extra day contributed approximately $1.5 billion of additional net sales across our businesses in Q1 2024, or about 120 basis points to the year-over-year growth rate, which impacted all segments. Q1 operating income is expected to be between $14 billion and $18 billion. This guidance includes the estimated impact of certain updates to the useful life of our fixed assets. I'll provide a bit more detail in a moment, but on an aggregate basis, we estimate this will decrease full-year 2025 operating income by approximately $400 million for the assets on our balance sheet as of December 31, 2024. First, in Q4, we completed a useful life study for our servers and network equipment and observed an increased pace of technology development. Particularly in the area of artificial intelligence and machine learning. As a result, we're decreasing the useful life for a subset of our servers and networking equipment from six years to five years beginning in January 2025. We anticipate this will decrease full-year 2025 operating income by approximately $700 million. In addition, we also early-retired a subset of our servers and network equipment. We recorded a Q4 2024 expense of approximately $920 million from accelerated depreciation and related charges and expect this will also decrease full-year 2025 operating income by. Both of these server and network equipment use for life changes prim”
