The impact of higher irrigation system unit volume was partially offset by the impact of higher raw material and other costs.
We continue to face some margin headwind as the realization of pricing actions lags the impact of cost increases.
Fourth quarter operating results were also reduced by approximately $5 million resulting from the impact of the LIFO method of accounting for inventory, under which higher raw material costs are recognized in cost of goods sold rather than in ending inventory values.
During the quarter, we added additional inventory as a buffer against supply chain uncertainty, expected cost increases and as part of a build ahead plan in connection with the temporary shutdown at the Lindsay, Nebraska facility to install productivity upgrades.
We expect to realize some benefit of this fourth quarter LIFO impact in future periods as inventory quantities decline.
