Phillips 66 (NYSE:PSX)

Gross property, plant and equipment exhibited a consistent upward trend between 2015 and 2019, increasing from 30,310 million USD to 38,071 million USD. Net property, plant and equipment followed a similar growth trajectory, rising from 19,721 million USD to 23,786 million USD. This overall expansion indicates a sustained period of capital investment across the organization's operational segments.

Segmental Capital Distribution

The refining segment remains the largest contributor to the asset base, growing from 20,850 million USD in 2015 to 23,692 million USD in 2019. While it holds the highest absolute value, its growth rate was more moderate compared to other segments.

The midstream segment demonstrated the most aggressive expansion, increasing from 6,978 million USD to 11,221 million USD. This represents a significant proportional increase in asset allocation, suggesting a strategic prioritization of midstream infrastructure.

Marketing and specialties assets grew steadily from 1,422 million USD to 1,847 million USD, while corporate and other assets fluctuated slightly, ending the period at 1,311 million USD.

Depreciation and Asset Valuation

Accumulated depreciation and amortization increased steadily from 10,589 million USD in 2015 to 14,285 million USD in 2019. The growth in accumulated depreciation is consistent with the aging of existing assets.

Despite the increase in accumulated depreciation, the growth in gross property, plant and equipment outpaced the depreciation rate, resulting in a net increase in the book value of assets over the five-year period.

The average age ratio of property, plant, and equipment demonstrates a gradual upward trend from 2015 through 2019, indicating an overall increase in the proportion of the assets' useful lives that have been consumed.

Short-term Stability (2015-2016)

Between December 31, 2015, and December 31, 2016, the average age ratio remained nearly constant, shifting marginally from 34.94% to 34.81%. This period reflects a state of equilibrium between asset depreciation and new capital additions.

Consistent Upward Progression (2017-2019)

A steady increase is observed starting in 2017, with the ratio rising to 36.40%, followed by 37.44% in 2018, and reaching 37.52% by December 31, 2019. This continuous rise indicates that the asset base is aging at a rate that exceeds the replacement of older assets with new investments.

Cumulative Impact

Over the five-year analyzed period, the ratio grew by 2.58 percentage points. The trend suggests a strategic shift or a cyclical phase characterized by the utilization of existing capacity rather than aggressive expansion of the fixed asset base.

The financial data indicates a consistent expansion of the capital asset base alongside a steady increase in accumulated depreciation over the five-year period from 2015 to 2019.

Gross Property, Plant, and Equipment (PP&E)

A persistent upward trend in gross PP&E is observed, with values increasing from 30,310 million USD in 2015 to 38,071 million USD by 2019. This growth reflects sustained capital investment in the company's physical infrastructure and operational capacity.

Accumulated Depreciation and Amortization (D&A)

Accumulated D&A rose incrementally from 10,589 million USD in 2015 to 14,285 million USD in 2019. This progression is consistent with the natural aging of the asset base and the systematic allocation of costs over the useful lives of the equipment.

Average Age Ratio

The average age ratio exhibited a general upward trajectory, starting at 34.94% in 2015 and reaching 37.52% by 2019. Following a marginal decrease to 34.81% in 2016, the ratio rose steadily over the subsequent three years. This trend indicates that the overall asset base is aging, as the rate of depreciation has slightly outpaced the relative impact of new capital additions on the total PP&E portfolio.
