The Committee of Sponsoring Organizations of the Treadway Commission (COSO) developed a model for evaluating internal controls which has been recognized as the generally accepted framework to monitor internal controls. The COSO framework includes five components: Environment Control, Risk Assessment, Control Activities, Information and Communication and Monitoring. Each component embodies the common thread of accountability to support a firm’s mission. According to AT&T’s 10K report, Section 9A describes the entity’s mission to “provide reasonable assurance” in keeping the integrity and reliability of their published financial statements. AT&T’s design for managing internal control upholds the five component framework of the COSO. Independent auditors Ernest and Young, LLP second the notion of well managed internal control by way of giving the firm an unqualified report. The success of the company speaks to the effective management of a firm’s internal controls. It’s no secret that AT&T is leading in the industry of communication and have been for several years. By executing the COSO framework, various risks that the company may face can be identified and assessed routinely at all levels and in within all functions of the organization
