Segment Reporting [Abstract]

Segment and Geographic Information

We are comprised of two primary operating segments, Materials and Delivery Systems and Services, under which we manage our operations and assess performance, and a Corporate segment. Our segments are differentiated by the types of products sold.

Materials

The Materials operating segment is an integrated provider of specialty materials for the high-growth electronics industry, focusing on the integrated circuit and flat-panel display markets. This segment provides the global semiconductor industry with high purity process materials for deposition, metallization, chamber cleaning and etching, chemicals mechanical planarization slurries, organosilanes, organometallics and liquid dopants for thin film deposition, and formulated chemical products for post-etch cleaning primarily for the manufacture of silicon and compound semiconductors and thin film transistor liquid crystal displays. The majority of our sales to the semiconductor industry are to large scale multinational companies.

Delivery Systems and Services

The Delivery Systems and Services operating segment designs, manufactures, installs, operates, and maintains chemical and gas delivery and distribution systems for specialty gases and chemicals delivered directly to our customers’ manufacturing tools. In addition, the business provides turnkey installation services during facility construction and startup as well as onsite operating services.

Corporate

The Corporate segment includes certain administrative costs that have been allocated to us such as information technology, general services, human resources, legal, accounting, and other services, as well as foreign exchange gains and losses, and other income and expense that cannot be directly associated with operating segments. Corporate assets primarily include cash and deferred tax assets.

Customers

For the fiscal years ended September 30, 2016, 2015, and 2014, three customers accounted for 10% or more of combined sales from both the Materials and Delivery Systems and Services segments. In 2016, these customers accounted for 21%, 13% and 13% of our combined sales. In 2015, these customers accounted for 21%, 13% and 11% of our combined sales. In 2014, these customers accounted for 19%, 14%, and 11% of our combined sales. No other customer accounted for more than 10% of combined sales in any period.

Products

For the fiscal years ended September 30, 2016 and 2015, a Materials segment product accounted for 10% or more of combined sales from both the Materials and Delivery Systems and Services segments. For the fiscal years ended September 30, 2016 and 2015, this product accounted for 12% and 11% of our combined sales, respectively.

Accounting Policies

The accounting policies of the segments are the same as those described in Note 2, Major Accounting Policies. We evaluate the performance of segments based upon reported segment operating income. Intersegment sales are not material and are recorded at selling prices that approximate market prices.
