The largest operating businesses engage in loan servicing; education technology, services, and payment processing; and communications. A significant portion of the Company's revenue is net interest income earned on a portfolio of federally insured student loans. The Company also makes investments to further diversify the Company both within and outside of its historical core education-related businesses, including, but not limited to, investments in real estate, early-stage and emerging growth companies, and renewable energy. Substantially all revenue from external customers is earned, and all long-lived assets are located, in the United States.</span></div><div style="text-align:justify;margin-bottom:9pt;"><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;">The Company was formed as a Nebraska corporation in 1978 to service federal student loans for two local banks. The Company built on this initial foundation as a servicer to become a leading originator, holder, and servicer of federal student loans, principally consisting of loans originated under the Federal Family Education Loan Program (“FFELP” or “FFEL Program”) of the U.S. Department of Education (the “Department”).</span></div><div style="text-align:justify;margin-bottom:9pt;"><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;">The Health Care and Education Reconciliation Act of 2010 (the “Reconciliation Act of 2010”) discontinued new loan originations under the FFEL Program, effective July 1, 2010, and requires that all new federal student loan originations be made directly by the Department through the Federal Direct Loan Program. This law does not alter or affect the terms and conditions of existing FFELP loans. As a result of this law, the Company no longer originates new FFELP loans. To reduce its reliance on interest income on student loans, the Company has expanded its services and products. This expansion has been accomplished through internal growth and innovation as well as business acquisitions.</span></div><div style="text-align:justify;margin-bottom:9pt;"><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;">The Company has four reportable operating segments.
