[1] As of September 30, 2025, the Group had net taxable losses arising from the operations of PPWM and WEALTH AI of HK$3,620,462 (US$462,442) and SGD$1,353,803 (US$1,027,649), respectively. These losses were available to reduce future taxable income, and all of these losses can be carried forward indefinitely. The Group considers positive and negative evidence to determine whether some portion or all of the deferred tax assets will more likely than not be realized. This assessment considers, among other matters, the nature, frequency and severity of recent losses, forecasts of future profitability, the duration of statutory carry forward periods, the Group’s experience with tax attributes expiring unused and tax planning alternatives. On the basis of this evaluation, the Group recognized a valuation allowance against deferred tax assets on tax loss carry-forwards of $251,333 for the years ended September 30, 2025.
