An analysis of property, plant, and equipment from 2017 through 2021 reveals a consistent and aggressive expansion of the asset base. Gross property and equipment increased from $1.93 billion to $4.28 billion over the five-year period, representing a total growth of approximately 122%. This expansion is reflected in the net book value, which rose from $773.7 million in 2017 to $2.08 billion by the end of 2021.

Equipment Growth
The equipment category represents the most significant driver of asset growth, increasing from $1.09 billion in 2017 to $2.60 billion in 2021. This trajectory indicates a sustained investment in hardware and technical infrastructure to support operational scaling.
Software and Infrastructure Investment
Capitalized software showed a steady upward trend, nearly doubling from $472.1 million in 2017 to $948.7 million in 2021. Similarly, furniture and leasehold improvements grew from $314.9 million to $470.7 million, suggesting a concurrent expansion of physical office capacity and proprietary technological capabilities.
Construction in Progress (CIP) Volatility
Construction in progress exhibited a non-linear trend, peaking at $349.9 million in 2020 before declining to $261.3 million in 2021. The decline in the final year suggests that several major projects were completed and subsequently transferred from construction in progress to the active equipment or leasehold improvement accounts.
Depreciation and Asset Aging
Accumulated depreciation and amortization increased from $1.15 billion in 2017 to $2.20 billion in 2021. While the absolute value of depreciation has grown, the pace of new capital expenditures has outstripped depreciation expenses, resulting in a substantial increase in net property and equipment.

The overall financial pattern indicates a strategic shift toward higher capital intensity. The growth in net assets suggests that the company significantly scaled its physical and digital infrastructure to accommodate growth, with a particular emphasis on hardware and software capitalization.

The analysis of property, plant, and equipment reveals a strategic shift in the lifecycle management of assets between 2017 and 2021. A general trend toward the rejuvenation of the asset base is evident, accompanied by a notable extension of estimated utility periods.

Average Age Ratio
The average age ratio remained relatively stable at approximately 60% from 2017 through 2019, followed by a consistent decline to 51.40% by the end of 2021. This downward trajectory indicates that the asset base is becoming younger relative to its total useful life, which typically reflects recent significant capital investments in new equipment.
Useful Life Estimations
A progressive increase in the estimated total useful life is observed, rising from 6 years in 2017 to 9 years in 2021. This extension directly contributed to an increase in the estimated remaining life, which grew from 2 years in 2017 to 4 years in 2021. Such adjustments suggest a revision in the expected durability of assets or a shift toward acquiring hardware with longer operational lifespans.
Temporal Asset Progression
The estimated age, representing the time elapsed since purchase, remained stagnant at 3 years from 2017 to 2019 before increasing to 4 years in 2020 and 2021. While the existing assets have aged, the simultaneous decrease in the average age ratio confirms that the acquisition of newer assets has offset the natural aging process of the older inventory.

2021 Calculations

1 Average age = 100 × Accumulated depreciation and amortization ÷ Property and equipment, gross
= 100 × 2,201,799 ÷ 4,283,959 = 51.40%


The analysis of property, plant, and equipment reveals a period of significant expansion in the asset base, coupled with a strategic shift in the age profile of those assets toward the end of the observed period.

Gross Property and Equipment
A consistent upward trajectory is observed in the gross value of assets, which increased from 1,928,088 thousand US dollars in 2017 to 4,283,959 thousand US dollars by 2021. The growth accelerated notably between 2019 and 2021, indicating a substantial increase in capital expenditures.
Accumulated Depreciation and Amortization
Accumulated depreciation increased steadily from 1,154,373 thousand US dollars in 2017 to 2,201,799 thousand US dollars in 2021. While these values rose in absolute terms, the growth rate was consistently lower than the expansion of the gross asset base.
Average Age Ratio
The average age ratio remained relatively stable between 2017 and 2019, fluctuating within a narrow range around 60%. A distinct downward trend emerged in 2020 and 2021, with the ratio declining to 55.47% and 51.40%, respectively.

The divergence between the rapid increase in gross assets and the declining average age ratio suggests a significant modernization of the infrastructure. The reduction in the ratio indicates that new assets were acquired at a pace that outweighed the depreciation of existing assets, effectively lowering the average age of the total property and equipment portfolio and suggesting a refreshed asset lifecycle.

2021 Calculations

1 Estimated total useful life = Property and equipment, gross ÷ Depreciation expense
= 4,283,959 ÷ 503,600 = 9


Between 2017 and 2021, a consistent expansion in the gross value of property and equipment was observed, accompanied by a gradual increase in annual depreciation expenses and a notable upward adjustment in the estimated useful life of assets.

Gross Property and Equipment Growth
The gross value of property and equipment exhibited a sustained upward trajectory, increasing from 1,928,088 thousand US dollars in 2017 to 4,283,959 thousand US dollars by 2021. This represents a total increase of approximately 122% over the five-year period, with the most significant acceleration occurring between 2020 and 2021.
Evolution of Estimated Useful Life
The estimated total useful life of assets showed initial volatility, decreasing from 6 years in 2017 to 5 years in 2018. However, from 2019 onward, a steady increase was recorded, with the estimated life extending to 6 years in 2019, 7 years in 2020, and reaching 9 years by 2021. This indicates a strategic shift toward longer amortization periods for the company's asset base.
Depreciation Expense Analysis
Annual depreciation expenses rose consistently from 349,300 thousand US dollars in 2017 to 503,600 thousand US dollars in 2021. Despite the substantial growth in gross property and equipment, the rate of increase in depreciation expense remained relatively moderate. This divergence is attributable to the extension of the estimated useful life; by increasing the depreciation period from 6 to 9 years, the annual impact of asset acquisition on the income statement was effectively reduced.

2021 Calculations

1 Time elapsed since purchase = Accumulated depreciation and amortization ÷ Depreciation expense
= 2,201,799 ÷ 503,600 = 4


The financial trajectory of the company's property, plant, and equipment indicates a consistent increase in both the accumulated depreciation and the annual depreciation expenses over the five-year period ending December 31, 2021.

Accumulated Depreciation and Amortization Trends
A steady upward trajectory is evident in accumulated depreciation, which grew from 1,154,373 thousand US dollars in 2017 to 2,201,799 thousand US dollars by 2021. This represents a significant increase in the total amount of asset cost allocated as expense over the assets' useful lives, indicating a growing cumulative wear and tear on the existing asset base.
Annual Depreciation Expense Analysis
Depreciation expenses have risen annually, starting at 349,300 thousand US dollars in 2017 and reaching 503,600 thousand US dollars in 2021. The consistent year-over-year growth suggests a continuous expansion of the capital asset base or the acquisition of higher-value equipment requiring greater annual write-downs.
Asset Age and Lifecycle
The time elapsed since purchase remained stable at three years from 2017 through 2019, before increasing to four years in 2020 and 2021. This shift indicates a maturing asset portfolio, where the weighted average age of the property, plant, and equipment has increased, reflecting a period of longer asset retention or a slowing pace of new capital acquisitions relative to the existing base.

2021 Calculations

1 Estimated remaining life = Property and equipment, net ÷ Depreciation expense
= 2,082,160 ÷ 503,600 = 4


A consistent expansion of the asset base is evident between 2017 and 2021, characterized by an accelerating increase in net property and equipment alongside a gradual extension of the estimated remaining useful life of those assets.

Net Property and Equipment Growth
The net book value of property and equipment experienced continuous growth, rising from 773,715 thousand US dollars in 2017 to 2,082,160 thousand US dollars by 2021. The growth rate accelerated significantly in the latter two years of the period, indicating a period of intensified capital investment in infrastructure.
Depreciation Expense Trends
Depreciation expenses rose steadily from 349,300 thousand US dollars in 2017 to 503,600 thousand US dollars in 2021. Although the expense grew in absolute terms, the rate of increase was more moderate than the growth of the net asset base, suggesting that the newly acquired assets may be subject to different depreciation schedules.
Analysis of Estimated Remaining Life
The estimated remaining life of assets remained constant at two years from 2017 through 2019, before increasing to three years in 2020 and four years in 2021. This upward trend is atypical for a static asset pool and strongly indicates the acquisition of new assets with longer useful lives, which shifted the weighted average remaining life of the total asset portfolio upward.
