| [i] | During the year ended December 31, 2019, the Company had non-taxable capital gains mainly related to the sale of the FP&C business [note 3] .
| [ii] | GAAP requires that the Company assess whether valuation allowances should be established or maintained against its deferred tax assets, based on consideration of all available evidence, using a “more-likely-than-not” standard. The factors the Company uses to assess the likelihood of realization are its history of losses, forecasts of future pre-tax income and tax planning strategies that could be implemented to realize the deferred tax assets.
During the year ended December 31, 2018, the Company released certain of its valuation allowance against deferred tax assets on its Canadian capital losses as a result of the anticipated capital gain from the sale of the FP&C business [note 3] . Additionally, the Company released the valuation allowance set up against deferred tax assets in India. The net effect of these valuation allowance releases was $52 million.
| [iii] | On December 22, 2017, the United States enacted the Tax Cuts and Jobs Act [the “US Tax Reform”]. At December 31, 2017, in accordance with guidance provided by Securities and Exchange Commission Staff Accounting Bulletin No. 118 [”SAB 118”], the Company made a reasonable estimate of its effects and recognized a provisional $23 million net reduction in income tax expense. In the fourth quarter of 2018, the Company completed its analysis of the tax impact and recorded a net increase of $11 million in income tax expense.
