The course text (Porter, Simon & Hatherly, 2014, pp. 132-139) contains introductory material on this area. There has been extensive academic research. The starting point into this might be some of the additional reading identified for this area in the course text (Habib, 2012; Quick & Warming-Rasmussen, 2009), although the most comprehensive summary of the literature in this area is Beattie & Fearnley (2002), although it cannot be taken as up-to-date on current regulation. The easiest way into an understanding of recent regulatory developments in the UK and EU could be any one of the many articles on professional websites (ICAEW, 2016). International regulation on the provision of non-audit services can be found in the handbook of the IESBA (IFAC, 2015).
