The choice of fair values could increase audit fees and/or auditors' efforts since fair value accounting increases the difficulty of verifiability and complexity (Ettredge et al., 2013). Even observed prices may introduce uncertainty to auditors, especially in distressed markets (Bratten et al., 2013). In addition, Kumarasiri and Fisher (2011) found that auditors are generally not knowledgeable enough to ascertain fair value estimates. Moreover, fair values can lead to higher audit fees and/or risks as they increase agency costs. As the fair value model for non-financial assets requires numerous inputs and models based on managerial assumptions, estimation uncertainty exists and active markets do not exist. Therefore managers have opportunities to manipulate earnings (Bratten et al, 2013 and Fiechter, Meyer, 2009; and others3).
