over financial reporting is done on a quarterly basis so that the conclusions concerning effectiveness of those controls can be  reported in NNN’s Quarterly Reports on Form 10-Q and Annual Report on Form 10-K. Based upon the assessments, NNN’s Chief Executive Officer and Chief Financial Officer have concluded that, as of  December 31, 2013, NNN’s disclosure controls and procedures were effective. Management, including NNN’s Chief Executive Officer and Chief Financial Officer, are responsible for establishing and  maintaining adequate internal control over financial reporting for NNN. Management used the criteria issued by the Committee  of Sponsoring Organizations of the Treadway Commission in Internal Control – 1992 Integrated Framework to assess the  effectiveness of NNN’s internal control over financial reporting. Based upon the assessments, NNN’s Chief Executive Officer  and Chief Financial Officer have concluded that, as of December 31, 2013, NNN’s internal control over financial reporting was  effective. Ernst & Young LLP, NNN’s independent registered public accounting firm, audited the financial statements included in this  Annual Report on Form 10-K and has issued an attestation report on NNN’s effectiveness of internal control over financial  reporting, which appears in this Annual Report on Form 10-K. During the three months ended December 31, 2013, there were no changes in NNN’s internal control over financial reporting  that materially affected, or are reasonably likely to materially affect, NNN’s internal control for financial reporting. Management, including NNN’s Chief Executive Officer and Chief Financial Officer, do not expect that NNN’s disclosure  controls and procedures or NNN’s internal control over financial reporting will prevent all errors and all fraud. A control  system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of  the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and  the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no  evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within NNN have  been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that  breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of  some persons, by collusion of two or more people, or by management’s override of the control. The design of any system of  controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that  any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become  inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate.  Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be  detected. Item 9B.
