nstead of using bank data, they sample closedend mutual funds which typically have investment securities (reported at fair values) prising virtually all their assets and with negligible liabilities and other assets. This is an advantage because the potential problem introduced by measuring some assets and liabilities at fair value but others at historical cost, is eliminated. Significant association between share prices and the fair value of investment securities, as well as between share returns and fair value securities gains and losses are found. To examine whether differences in the reliability of the fair value of investment securities affect investors’ 3 assessments of the usefulness of the information, Carroll et al. (2020) examine the association between share prices and fair values across different fund types and find that in all cases, including those traded in thin markets, there is a significant association between the share prices and fair values. In contrast, Danbolt and Rees (2020), using UK data, report no support for full fair value accounting. While fair value ine is considerably more valuerelevant than historic cost ine, the higher relevance disappears in the presence of changes in fair value accounting balance sheet values. Danbolt and Rees (2020) interpret their results as evidence of the absence of an obvious advantage from adopting fair value ine accounting if fair value balance sheet values are available to the user. Valuerelevance research studies the association between fair value estimates and share prices or returns. Sloan (1999) ments that while this association provides evidence that investors find fair value estimates to be relevant, the inferences regarding reliability are indirect and limited by the fact that share prices reflect many factors other than the fair value estimates. Dietrich et al. (2020) subsequently use a direct approach to investigate the reliability of mandatory annual fair value appraisal estimates by chartered surveyors for UK investment properties and find that appraisal estimates understate actual selling prices but are considerably less biased and more accurate measures of selling price than respective historical costs. Dietrich et al. (2020) also find that the reliability of appraisal estimates increases when monitored by external appraisers and Big Six auditors. The New Zealand (hereafter NZ) SSAP No. 17 ‘Accounting for Investment Properties and Properties Intended for Sale’ (NZSA, 1989) previously allowed NZ panies the choice of recognising unrealised gains or losses either in the ine statement, or as movements in an investment property revaluation reserve, unless the total of the reserve was insufficient to cover a deficit, in which case the amount of deficit was to be charged in the ine statement as part of operating results. The NZ equivalent of IAS 40 came into effect on 1 January 2020, resulting in the elimination of the choice of recognising unrealised gains in the revaluation reserve. OwusuAnsah and Yeoh (2020) investigate the relative valuerelevance of the two alternative 4 accounting treatments for unrealised gains on investment properties, based on a sample of NZ panies over the period 1990 to 1999, when the choice was still available. Their results show that recognition of unrealised gains in the ine statement is not superior to recognition of unrealised gains in the revaluation reserve in terms of their valuerelevance. However, OwusuAnsah and Yeoh (20
