Background information You are the audit senior with Rogers & Brown and you have been approached to undertake the audit of Reliable Printers Ltd (RPL) for the year ended 30 June 2015, taking over from the small audit firm of Jones & Associates. RPL prints books, magazines and advertising material for the publishing, educational and advertising industries on a print-on-demand basis. Printing on demand means that publishers can print the exact quantities ordered by retail outlets, rather than estimating in advance how many books are required and often printing too few or too many. The average print turnaround time for RPL is two business days for small orders and five to ten business days for large orders. In addition, four years ago, RPL further expanded its earnings base by having pub- lisher's titles available as searchable 'e-books' that could be downloaded directly by readers from RPL's web site.
