It also addresses, when applicable, the responsibilities of the engagement quality control reviewer. This section also applies, adapted as necessary, to other engagements conducted in accordance with generally accepted auditing standards (GAAS) (for example, a review of interim financial information conducted in accordance with section 930, Interim Financial Information).

System of Quality Control and the Role of the Engagement Teams
.03 Quality control systems, policies, and procedures are the responsibility of the audit firm. Under QC section 10, A Firm's System of Quality Control, the firm has an obligation to establish and maintain a system of quality control to provide it with reasonable assurance that
the firm and its personnel comply with professional standards and applicable legal and regulatory requirements and
reports issued by the firm are appropriate in the circumstances.
.04 Within the context of the firm's system of quality control, engagement teams have a responsibility to implement quality control procedures that are applicable to the audit engagement and provide the firm with relevant information to enable the functioning of that part of the firm's system of quality control relating to independence.
.05 Engagement teams are entitled to rely on the firm's system of quality control, unless the engagement partner determines that it is inappropriate to do so based on information provided by the firm or other parties.
.06 The engagement partner may use the assistance of other members of the engagement team or other personnel within the firm in meeting the requirements of this section. The requirements imposed by this section on engagement partners do not relieve other members of the engagement team of any of their professional responsibilities.
.07 This section is effective for engagements conducted in accordance with GAAS for periods ending on or after December 15, 2012.
.08 The objective of the auditor is to implement quality control procedures at the engagement level that provide the auditor with reasonable assurance that
the audit complies with professional standards and applicable legal and regulatory requirements and
the auditor's report issued is appropriate in the circumstances."

.13 The engagement partner should form a conclusion on compliance with independence requirements that apply to the audit engagement. In doing so, the engagement partner should
obtain relevant information from the firm and, when applicable, network firms to identify and evaluate circumstances and relationships that create threats to independence;
evaluate information on identified breaches, if any, of the firm's independence policies and procedures to determine whether they create a threat to independence for the audit engagement; and
take appropriate action to eliminate such threats or reduce them to an acceptable level by applying safeguards or, if considered appropriate, to withdraw from the audit engagement when withdrawal is possible under applicable law or regulation.The engagement partner should promptly report to the firm any inability to resolve the matter so that the firm may take appropriate action.
