This thesis explores write-offs in exploration and evaluation (EE) assets reported by the pre-production Australian Mining Development Stage Entities (MDSEs). The financial reporting of MDSEs is subject to a specific principles-based accounting standard AASB 6, πΈπ₯ππππππ‘πππ πππ πππ πΈπ£πππ’ππ‘πππ ππ πππππππ π

This reporting flexibility gives rise to managerial discretion in recording assets and can have a potential impact on asset quality. This study primarily evaluates different accounting choices in reporting EE costs at the firm level. This disclosure of information ultimately has a bearing over the impairment of the EE assets and the valuation of the firms.
To begin with, this thesis is the first comprehensive analysis on accounting choices under AASB6 since the Lourens and Henderson (1972) survey. It provides evidence of current accounting choices made by MDSEs to capitalise or to expense EE costs. This study further examines the determinants and market reactions of write-offs amongst MDSEs in the Australian mining sector. The latter signals a demarcation when uncertainty is resolved.
It is observed that capitalisation remains the dominating accounting choice for MDSEs. This descriptive finding holds in both the pre- and post-IFRS adoption periods. Based on descriptive statistics, firms choosing capitalization method, tend to have weaker financials with low cash balances, lower profitability and lower levels of equity funding. The expensing method tends to be used by firms with stronger financials with high cash balances, larger asset base, higher profitability and more equity funding.
In terms of the propensity to impair EE assets, impairment is more likely to occur amongst firms with a high proportion of non-exploration spending relative to exploration-related spending, high cash burn rates, before obtaining project debt financing, during the mining boom. However, firms holding large EE assets with high book to market ratios, using nonβBig 4 specialist auditors are associated with higher write-offs reported.
In assessing the impact of write-offs on equity valuation, on the announcement date, negative short windows (event date and 3 to 5-day abnormal buy-and-hold returns) are observed following price sensitive announcements, when information is derived from βpreliminary finalβ reports.
