CHS Inc. (referred to herein as "CHS," "we," "us" or "our") is the nation's leading integrated agricultural cooperative, providing grain, foods and energy resources to businesses and consumers on a global basis. As a cooperative, we are owned by farmers and ranchers and their member cooperatives (referred to herein as "members") across the United States. We also have preferred shareholders that own shares of our five series of preferred stock, which are each listed and traded on the Nasdaq Global Select Market. We buy commodities from and provide products and services to individual agricultural producers, local cooperatives and other companies (including our members and other non-member customers), both domestically and internationally. We provide a wide variety of products and services, ranging from initial agricultural inputs such as fuels, farm supplies, crop nutrients and crop protection products to agricultural outputs that include grains and oilseeds, grain and oilseed processing, renewable fuels and food products. A portion of our operations are conducted through equity investments and joint ventures whose operating results are not fully consolidated with our results; rather, a proportionate share of the income or loss from those equity investments and joint ventures is included as a component of our net income using the equity method of accounting. For the year ended August 31, 2019, our total revenues were $31.9 billion and net income attributable to CHS Inc. was $829.9 million.
We have aligned our segments based on an assessment of how our businesses operate and the products and services they sell. Our Energy segment derives its revenues through refining, wholesaling and retailing of petroleum products. Our Ag segment derives its revenues through origination and marketing of grain, including service activities conducted at export terminals; through wholesale agronomy sales of crop nutrient and crop protection products; from sales of soybean meal, soybean refined oil and soyflour products; through the production and marketing of renewable fuels; and through retail sales of petroleum and agronomy products, processed sunflowers, feed and farm supplies. Our Ag segment also records equity income from our grain export joint venture and other investments. Our Nitrogen Production segment consists solely of our equity method investment in CF Industries Nitrogen, LLC ("CF Nitrogen"). Our other business operations, primarily our financing and hedging businesses, are included in Corporate and Other because of the nature of their products and services, as well as the relative amount of revenues for those businesses. Prior to its sale on May 4, 2018, our insurance business was also included in Corporate and Other. In addition, our non-consolidated wheat milling and food production and distribution joint ventures are included in Corporate and Other.
Our earnings from cooperative business are allocated to members (and to a limited extent to non-members with which we have agreed to do business on a patronage basis) based on the volume of business they do with us. We allocate these earnings to our patrons in the form of patronage refunds (which are also called patronage dividends), which may be in cash, patrons' equities (in the form of capital equity certificates) or both. Patrons' equities may be redeemed over time solely at the discretion of our Board of Directors. Earnings derived from non-members, which are not treated as patronage, are taxed at federal and state statutory corporate rates and are retained by us as unallocated capital reserves. We also receive patronage refunds from the cooperatives in which we are a member, if those cooperatives have earnings to distribute and if we qualify for patronage refunds from them.
