SEGMENT AND GEOGRAPHIC INFORMATION The Companys business consists of the Water Systems, Distribution, and Fueling Systems reportable segments, based on the principal end market served. Within the Water Systems segment, North America Water Systems and International Water Systems have been identified as operating segments. For reportable segment purposes, the Company aggregates North America Water Systems and International Water Systems into the Water Systems segment, as they meet the aggregation criteria in FASB ASC 280. The Company includes unallocated corporate expenses and inter-company eliminations in an Intersegment Eliminations/Other segment that together with the Water Systems, Distribution, and Fueling Systems segments, represent the Company. The Water Systems segment designs, manufactures and sells motors, pumps, electronic controls and related parts and equipment primarily for use in submersible water and other fluid system applications. The Fueling Systems segment designs, manufactures and sells pumps, electronic controls and related parts and equipment primarily for use in submersible fueling system applications. The Fueling Systems segment integrates and sells motors and electronic controls produced by the Water Systems segment. The Distribution segment sells to and provides pre sale support and specifications to the installing contractors. The Distribution segment sells products produced by the Water Systems segment. In the prior year, the Company reported certain product transfers between Water and Fueling as intersegment revenue. The Company is now reporting these product transfers between Water and Fueling as inventory transfers as a significant number of the Company's manufacturing facilities are shared across segments for scale and efficiency purposes. The Company continues to report intersegment transfers from Water to Distribution as intersegment revenue at market prices to properly reflect the commercial arrangement of vendor to customer that exists between the Water and Distribution segments. Segment operating income is a key financial performance measure. Operating income by segment is based on net sales less identifiable operating expenses and allocations and includes profits recorded on sales to other segments of the Company. The Company has retrospectively revised segment results in prior periods to conform with current period presentations. There is no impact on the Company's previously reported consolidated financial position, results of operations, or cash flows. The accounting policies of the Companys reportable segments are the same as those described in Note 1 (Summary of Significant Accounting Policies). Performance is evaluated based on the sales and operating income of the segments and a variety of ratios to measure performance. These results are not necessarily indicative of the results of operations that would have occurred had each segment been an independent, stand-alone entity during the periods presented.
