Auditors worldwide will have access to 36 newly updated and clarified auditing standards as part of the International Auditing and Assurance Standards Board's Clarity Project. Seven clarified ISAs have been issued as part of the project and are set to be approved by the US Public Interest Oversight Board as part of due process. The IAASB has issued all its auditing standards in a form which, it says, is 'designed to enhance the understanding and implementation of them'. The clarified standards are effective for audits of financial statements for periods beginning on or after 15 December 2009. IAASB chair Arnold Schilder said: 'We are pleased to now make the full suite of standards available so that our stakeholders can take the necessary steps to ensure these standards are properly implemented in advance of their effective date.' Titles of the seven final clarified ISAs all featured on the IAASB website at www.ifac.org/IAASB.
