Gross property, plant, and equipment exhibited a consistent upward trend over the analyzed period, increasing from 10,186 million USD in June 2018 to 12,250 million USD by June 2023. This growth indicates a sustained commitment to expanding the physical asset base to support operational requirements.

Capital Investment in Machinery and Equipment
Machinery and equipment constitute the primary component of the asset portfolio. This category grew from 7,209 million USD in 2018 to 8,704 million USD in 2023, representing the most significant driver of the increase in gross property, plant, and equipment. The steady growth suggests ongoing investments in production capacity and technological upgrades.
Analysis of Construction-in-Process
A significant acceleration in construction-in-process is observed, rising from 234 million USD in 2018 to 798 million USD in 2023. The sharp increase, particularly from 2020 onward, points toward a substantial increase in ongoing facility expansions or equipment installations that have not yet been transitioned to active service.
Depreciation and Asset Aging
Accumulated depreciation rose steadily from 7,091 million USD in 2018 to 8,630 million USD in 2023. The growth in accumulated depreciation is commensurate with the increase in gross assets, reflecting the systematic allocation of costs over the useful lives of the equipment and facilities.
Net Asset Value Trends
Property, plant, and equipment, net, experienced initial volatility, dipping to 2,843 million USD in 2019 before trending upward to reach 3,620 million USD by June 2023. This recovery and subsequent growth indicate that capital expenditures in later years outpaced the annual depreciation expense, resulting in an overall increase in the net book value of the asset base.
Stability of Other Asset Categories
Buildings and improvements remained relatively stable, ending the period at 1,955 million USD, close to the 1,949 million USD recorded in 2018. Land values showed a slight downward trend, decreasing from 306 million USD to 269 million USD, while computer equipment and software fluctuated within a narrow range between 429 million USD and 494 million USD.

An analysis of the property, plant, and equipment ratios reveals a strategic extension of asset utility over the six-year period ending June 30, 2023. While the asset base has aged chronologically, a simultaneous upward revision of estimated total useful lives has resulted in an overall increase in the projected remaining operational lifespan of the equipment.

Estimated Total Useful Life
A consistent upward trend is observed, with the estimated total useful life increasing from 11 years in 2018 to 17 years by 2023. This indicates a significant expansion in the expected duration of asset productivity, potentially reflecting technological improvements or a change in accounting estimates regarding the longevity of the equipment.
Asset Age and Remaining Life Progression
The estimated age of assets progressed from 8 years in 2018 to 12 years in 2023. Despite this natural aging process, the estimated remaining life increased from 3 years to 5 years over the same period. This suggests that the extension of the total useful life has outpaced the chronological aging of the assets, effectively adding two years of projected utility to the asset base.
Average Age Ratio Stability
The average age ratio remained relatively stable, fluctuating within a range of 70.93% to 74.42%. A peak occurred in July 2020 at 74.42%, followed by a decline to a period low of 70.93% in July 2022, before settling at 72.03% in June 2023. The persistence of this ratio above 70% indicates that the asset base is consistently comprised of equipment that is well into its estimated useful life.

2023 Calculations

1 Average age = 100 × Accumulated depreciation ÷ (Property, plant and equipment, gross – Land)
= 100 × 8,630 ÷ (12,250 – 269) = 72.03%


The financial trajectory of property, plant, and equipment indicates a general expansion of the asset base coupled with a steady increase in accumulated depreciation over the six-year period. While gross assets grew, the average age of those assets fluctuated, reflecting distinct cycles of capital investment and asset aging.

Gross Property, Plant, and Equipment Trends
Gross PP&E increased from 10,186 million USD in 2018 to 12,250 million USD by 2023. The most significant growth was observed between 2021 and 2023, suggesting a period of intensified capital expenditure to expand production capacity or modernize technological infrastructure.
Accumulated Depreciation Analysis
Accumulated depreciation rose consistently each year, moving from 7,091 million USD in 2018 to 8,630 million USD in 2023. This steady climb reflects the continuous allocation of asset costs over their useful lives and a growing volume of depreciable assets.
Average Age Ratio Dynamics
The average age ratio exhibited a non-linear trend, rising from 71.77% in 2018 to a peak of 74.42% in 2020. This upward movement indicates that the existing asset base was aging faster than it was being replaced. Subsequently, the ratio declined to 70.93% by 2022, which correlates with the increase in gross PP&E, implying that the acquisition of new assets effectively rejuvenated the portfolio. A slight reversal occurred in 2023, with the ratio returning to 72.03%.
Land Asset Stability
Land holdings remained relatively stable with a slight downward trend, decreasing from 306 million USD in 2018 to 269 million USD in 2023, indicating minimal strategic shifts in real estate holdings during this period.

2023 Calculations

1 Estimated total useful life = (Property, plant and equipment, gross – Land) ÷ Depreciation expense for property, plant and equipment
= (12,250 – 269) ÷ 695 = 17


A comprehensive analysis of the property, plant, and equipment (PP&E) reveals a divergence between asset growth and depreciation expenses over the six-year period ending June 30, 2023. While the gross value of PP&E increased steadily, the annual depreciation expense followed a consistent downward trajectory.

Asset Base Expansion
Gross property, plant, and equipment grew from US$ 10,186 million in June 2018 to US$ 12,250 million by June 2023. This represents a total increase of approximately 20.3%, indicating a sustained commitment to capital investment and the expansion of the company's operational infrastructure.
Useful Life Extension
The estimated total useful life of assets was progressively extended throughout the period, rising from 11 years in 2018 to 17 years in 2022 and 2023. This represents a 54.5% increase in the expected longevity of the asset base.
Depreciation Expense Correlation
A notable inverse relationship exists between the gross asset value and the depreciation expense. Despite the increase in total assets, the annual depreciation charge decreased from US$ 871 million in 2018 to US$ 695 million in 2023. This reduction is directly attributable to the extension of the estimated useful life, which spreads the cost of assets over a longer period, thereby reducing the annual non-cash expense recognized on the income statement.
Land Value Stability
The value of land remained relatively stable with a slight downward trend, decreasing from US$ 306 million in 2018 to US$ 269 million in 2023, suggesting that the growth in gross PP&E is driven primarily by depreciable equipment and facilities rather than real estate acquisition.

The observed patterns indicate a strategic shift in accounting estimates regarding asset longevity. By increasing the estimated useful life from 11 to 17 years, the company has effectively lowered its annual depreciation overhead while simultaneously growing its total asset base.

2023 Calculations

1 Time elapsed since purchase = Accumulated depreciation ÷ Depreciation expense for property, plant and equipment
= 8,630 ÷ 695 = 12


The financial data reveals a consistent aging trend of the property, plant, and equipment (PP&E) asset base over the six-year period ending June 30, 2023. There is a clear correlation between the increasing age of assets and a steady decline in annual depreciation expenses, suggesting a reduction in recent large-scale capital acquisitions.

Asset Age Evolution
The time elapsed since purchase has increased from 8 years in 2018 to 12 years by 2023. This upward trajectory indicates that the company's fixed asset base is maturing, with the average age of assets increasing by 50% over the analyzed timeframe.
Accumulated Depreciation Growth
Accumulated depreciation has shown a continuous increase, rising from 7,091 million US dollars in June 2018 to 8,630 million US dollars in June 2023. This growth reflects the cumulative write-down of asset values as they move through their useful life cycles.
Depreciation Expense Compression
A sustained downward trend is observed in the annual depreciation expense, which decreased from 871 million US dollars in 2018 to 695 million US dollars in 2023. This contraction suggests that a larger portion of the asset base is becoming fully depreciated, or that the volume of new capital expenditures is insufficient to offset the depreciation of older assets.

Collectively, these indicators point toward an aging infrastructure where the rate of asset depreciation is slowing down due to the depletion of the depreciable base. The steady rise in elapsed time since purchase, coupled with falling annual expenses, suggests a period of limited asset renewal.

2023 Calculations

1 Estimated remaining life = (Property, plant and equipment, net – Land) ÷ Depreciation expense for property, plant and equipment
= (3,620 – 269) ÷ 695 = 5


An analysis of long-term asset trends reveals a general expansion of net property, plant, and equipment alongside a strategic shift in depreciation parameters. While net assets experienced initial volatility, a growth trajectory was established between 2020 and 2022, reaching a peak of 3,670 million US dollars before slightly contracting to 3,620 million US dollars in 2023.

Estimated Remaining Life and Depreciation Dynamics
A direct correlation is observed between the extension of the estimated remaining life of assets and the reduction in annual depreciation expenses. The estimated remaining life remained constant at 3 years from 2018 through 2020, before increasing to 4 years in 2021 and further extending to 5 years by 2022. Parallel to this extension, depreciation expenses declined consistently every year, falling from 871 million US dollars in 2018 to 695 million US dollars in 2023. The increase in the estimated useful life of assets has effectively decelerated the rate of depreciation, thereby reducing the annual charge against earnings.
Asset Valuation and Composition
Net property, plant, and equipment grew by approximately 17% between 2018 and 2023. This overall growth occurred despite a steady decrease in land holdings, which declined from 306 million US dollars to 269 million US dollars. The contrast between the rising net PP&E and the falling value of land suggests that investment has been concentrated in depreciable capital assets, such as machinery or facilities, rather than in land acquisition.
