We then re-assess these findings by exploiting two alternative settings. First, to mitigate concerns that results are confined to the European setting, we reassess the relation of reporting model to audit fees by comparing audit pricing for UK real estate firms propensity score-matched with US real estate firms. Because the UK and US are among the world’s largest and most developed real estate markets, this leads to a larger sample size, and also isolates the primary difference between the countries for this industry: the financial reporting model. Specifically, UK firms report property assets at fair value under both domestic standards and IFRS, while US firms report them at amortized cost under domestic US standards. Further, while the US generally is considered to have higher audit litigation risk than other countries, prior research fails to designate the real estate industry as a high risk setting. Consistent with our previous results, we find that audit fees are significantly lower for firms reporting property assets at fair value (i.e., the UK firms) relative to amortized cost (i.e., the US firms), and that impairments are again a primary driver of this difference. Second, we re-assess the effects of exposure to fair value and complexity in fair value measurement using a sample of UK investment trusts. Restricting the analysis within the UK eliminates cross-country differences in institutional features as a potential source of variation in audit fees. Further, this industry allows a potentially stronger assessment of the difficulty to measure fair value by exploiting fair values for these firms’ financial assets calculated based on market inputs (level 1 fair values) versus those based on less reliable valuation inputs (level 2 and 3 fair values). Consistent with our previous results, we find that audit fees are decreasing in the firm’s exposure to assets reported at fair value, and increasing in the firm’s exposure to more difficult-to-measure (i.e., levels 2 and 3) fair values. Finally, we find that results are robust to numerous sensitivity analyses, including: (1) removal of firm-years potentially affected by the global financial crisis; (2) controlling for potential endogeneity of audit firm type; and (3) controlling for country effects.
