The annual data for materials and supplies reveals some variability over the five-year period ending in 2021. Overall, the values fluctuate within a relatively narrow band without a clear upward or downward long-term trend.
- Trend Analysis
- Starting at 222 million US dollars in 2017, the value decreases slightly to 207 million in 2018. There is then an increase in 2019 to 244 million, representing the peak in the period analyzed. Following this, the value drops again to 221 million in 2020 and declines slightly further to 218 million in 2021.
- Insights
- The data suggests moderate volatility from year to year rather than consistent growth or reduction. The peak in 2019 could indicate an operational or procurement event causing increased inventory or material requirements, while the declines in subsequent years may reflect normalization or optimization of asset levels.
- Summary
- In summary, materials and supplies values remained relatively stable over the period, with a notable peak in 2019 surrounded by small declines. This pattern suggests variability in supply management or demand but no strong directional shift.
