We are a full-service regional bank holding company focused on relationship-based business and agri-business banking. We serve our customers through 175 branches in attractive markets in nine states: Arizona, Colorado, Iowa, Kansas, Minnesota, Missouri, Nebraska, North Dakota and South Dakota. We were established more than 80 years ago and have achieved strong market positions by developing and maintaining extensive local relationships in the communities we serve. By leveraging our business and agri-business focus, highly efficient operating model, robust approach to risk management and presence in attractive markets, we have achieved steady and profitable growth-both organically and through disciplined acquisitions. We have successfully completed nine acquisitions since 2006, including our 2010 FDIC assisted acquisition of TierOne Bank, which represented approximately $2.54 billion in acquired assets, and our 2016 acquisition of HF Financial, which represented approximately $1.12 billion of acquired assets. Our net income was $167.4 million for fiscal year 2019 and our loans and total assets were $9.73 billion and $12.79 billion, respectively, at September 30, 2019.
We focus on business banking, complemented by our agri-business banking, retail banking and wealth management services. Our loan portfolio consists mainly of business loans, comprised of CRE loans and commercial non-real estate loans, which collectively accounted for 70.0% of our loan portfolio and agri-business loans, which accounted for 20.6% of our total loan portfolio at September 30, 2019. In addition, 70.5% of our aggregate loan portfolio was primarily secured by interests in real estate predominantly located in the states in which we operate, including 52.3% of CRE loans, 9.8% of agriculture real estate loans and 8.4% of residential real estate loans. In addition, some of our other lending occasionally involves taking real estate as primary or secondary collateral. We offer small and mid-sized businesses a focused suite of financial products and have established strong relationships across a diversified range of sectors, including key areas supporting regional growth such as hospitality/tourism, agri-business services, freight and transport and healthcare. We have developed extensive expertise in CRE and agri-business lending, which serves two of the most prominent industries across our markets, and we offer a variety of financial services designed to meet the specific needs of such customers. We also provide a range of deposit and loan products to our retail customers through several channels, including our branch network, online banking system, mobile banking applications and customer care centers. In our wealth management business, we seek to expand our private banking, financial planning, investment management and insurance operations to better position us to capture an increased share of the business of managing the private wealth of many of our business and agri-business customers.
Our banking model seeks to balance the best of being a "big enough" and a "small enough" bank, providing capabilities typical of a much larger bank, such as diversified product specialists, customized banking solutions and multiple delivery channels, with a customer-focused culture usually associated with smaller banks. Our focus on balancing these capabilities with a service-oriented culture is embedded within our operations and is enhanced by focusing on our core competencies. We are well recognized within our markets for our relationship-based banking model that provides for local, efficient decision making. We believe we serve our customers in a manner that is responsive, flexible and accessible. Our relationship bankers strive to build deep, long-term relationships with customers and understand the customers' specific needs to identify appropriate financial solutions. We believe we have been successful in attracting customers and bankers from larger competitors because of our flexible approach and the speed and efficiency with which we provide banking solutions to our customers while maintaining disciplined underwriting standards.
