The difference between the opening and closing balances of our accounts receivable, net, contract assets and deferred revenues primarily results from revenue growth and the timing difference between the satisfaction of our performance obligation and the customer's payment. The amounts of revenue recognized during the years ended December 31, 2025, 2024 and 2023 from the opening deferred revenue balance were $101 million, $88 million and $95 million, respectively. For the years ended December 31, 2025, 2024 and 2023, no impairment loss related to contract balances was recognized in the consolidated statements of operations.
Contract Costs
The ending balances of net capitalized contract costs as of December 31, 2025 and 2024 were $503 million and $436 million, respectively, which were included in other assets in the consolidated balance sheets. $119 million, $122 million, and $103 million of contract costs were amortized during years ended December 31, 2025, 2024 and 2023, respectively, which were included in sales and marketing expense in the consolidated statements of operations.
Remaining Performance Obligations
Approximately $13.6 billion of revenues, including deferred installation revenues, are expected to be recognized in future periods related to unsatisfied performance obligations as of December 31, 2025. Most of our revenue contracts have an initial term varying from one to five years, and thereafter, automatically renew in one-year increments. Included in the remaining performance obligations are contracts that are either under the initial term or under one-year renewal periods. We expect to recognize approximately 65% of our remaining performance obligations as revenues over the next two years, with more revenues expected to be recognized in the first year due to the impact of contract renewals. The remainder of the balance is generally expected to be recognized over the next three to five years. We estimate our remaining performance obligations at a point in time. Actual amounts and timing of revenue recognition may differ from these estimates due to changes in actual deployment dates, contract modifications, scheduled price increases, renewals and/or terminations.

The remaining performance obligations do not include variable consideration related to unsatisfied performance obligations such as the usage of metered power, service fees from xScale® data centers that are based on future events or actual costs incurred in the future, or any contracts that could be terminated without any significant penalties including the majority of interconnection revenues. The remaining performance obligations above include revenues to be recognized in the future related to arrangements where we are considered the lessor.

About Revenue Disclosures

Revenue disclosures under ASC 606 explain how a company identifies performance obligations, allocates transaction prices, and determines when revenue is recognized. This section is essential for understanding whether reported revenue reflects genuine economic activity or aggressive accounting choices. Analysts examine the mix of point-in-time versus over-time recognition, which directly affects revenue timing and comparability.

Key signals: rising contract liabilities (deferred revenue) suggest strong future revenue visibility, while declining contract assets may indicate slowing project milestones. Watch for variable consideration estimates — rebates, returns, and performance bonuses that require management judgment. Significant changes in disaggregated revenue by geography or product line can reveal shifting business mix before it appears in headline numbers. Compare revenue growth against contract liability growth to assess sustainability, and scrutinize any changes in the timing of recognition that coincide with earnings pressure.
