Total inventory levels exhibited a fluctuating trend between 2015 and 2019, with a notable peak occurring in 2018. The overall inventory balance increased from 635 million US dollars in 2015 to 671 million US dollars by the end of 2019, though the trajectory was non-linear, characterized by a significant spike in 2018 followed by a contraction in 2019.

Work in Process

This component represents the most substantial portion of the total inventory balance. It demonstrated significant volatility, declining from 583 million US dollars in 2016 to 504 million US dollars in 2017, before rising sharply to a peak of 662 million US dollars in 2018. The subsequent decrease to 574 million US dollars in 2019 suggests that fluctuations in total inventory are primarily driven by the timing and scale of production cycles within this category.

Materials and Purchased Parts

A steady and gradual upward trend is observed in the value of materials and purchased parts. After remaining relatively stable between 2015 and 2017, the balance grew from 69 million US dollars in 2017 to 78 million US dollars in 2019, indicating a moderate increase in the stock of raw inputs.

Finished Goods

Finished goods consistently maintained the lowest valuation of all inventory categories, fluctuating within a narrow range between 10 million and 21 million US dollars. The minimal level of finished goods relative to work in process suggests a production model focused on rapid delivery or specific order fulfillment rather than the accumulation of completed stock.
