ORGANIZATION	ORGANIZATION Kennametal Inc. was incorporated in Pennsylvania in 1943. Kennametal Inc. and its subsidiaries (collectively, Kennametal or the Company) are a leading global manufacturer and supplier of tooling, engineered components and advanced materials consumed in production processes. We believe that our reputation for manufacturing excellence, as well as our technological expertise and innovation we deliver in our products and services, helps us to achieve a leading position in our primary markets. End users of our products include metalworking and machinery manufacturers and suppliers across a diverse array of industries, including the aerospace, defense, transportation, machine tool, light machinery and heavy machinery, as well as producers and suppliers in a number of equipment-intensive industries such as coal mining, road construction and quarrying, as well as oil and gas exploration, refining, production and supply. Our end users' applications range from airframes to mining operations, engines to oil wells and turbochargers to processing. In order to take advantage of the growth opportunities of our WIDIA brand, we implemented a new operating structure at the beginning of fiscal 2017. A key attribute of the new structure is the establishment of the Widia operating segment. In order to better leverage the opportunities in this business, in addition to being more agile and competitive in the marketplace, we are placing higher levels of focus, determination and leadership in this business. The Industrial and Widia segments in 2017 were formed from the 2016 Industrial segment. We now have three global reportable operating segments: Industrial, Widia, and Infrastructure.
