The Group recognises the benefit of tax losses amounting to US$2,611 million (2018: US$3,758 million) only to the extent of anticipated future taxable income or gains in relevant jurisdictions. The amounts recognised in the Financial Statements in respect of each matter are derived from the Group’s best judgements and estimates as described in note 6 ‘Income tax expense’. The composition of the Group’s unrecognised deferred tax assets and liabilities is as follows:

(1) | At 30 June 2019, the Group had income and capital tax losses with a tax benefit of US$2,265 million (2018: US$1,946 million) and tax credits of US$1,455 million (2018: US$1,082 million), which are not recognised as deferred tax assets, because it is not probable that future taxable profits or capital gains will be available against which the Group can utilise the benefits.
The gross amount of tax losses carried forward that have not been recognised is as follows:
Year of expiry |  | Total |
|  | US$M |
Income tax losses |  |  |  |
Not later than one year |  |  | 359 |
Later than one year and not later than two years |  |  | 443 |
Later than two years and not later than five years |  |  | 2,723 |
Later than five years and not later than 10 years |  |  | 530 |
Later than 10 years and not later than 20 years |  |  | 2,312 |
Unlimited |  |  | 2,001 |
|  |  | 8,368 |
Capital tax losses |  |  |  |
Not later than one year |  |  | – |
Later than two years and not later than five years |  |  | – |
Unlimited |  |  | 4,114 |
Gross amount of tax losses not recognised |  |  | 12,482 |
Tax effect of total losses not recognised |  |  | 2,265 |
Of the US$1,455 million of tax credits, US$1,449 million expires not later than 10 years and US$6 million expires later than 10 years and not later than 20 years.
(2) | The Group had deferred tax assets of US$1,656 million at 30 June 2019 (2018: US$1,659 million) and deferred tax liabilities of US$2,253 million (2018: US$2,216 million) associated with undistributed earnings of subsidiaries that have not been recognised because the Group is able to control the timing of the reversal of the temporary differences and it is not probable that these differences will reverse in the foreseeable future.
(3) | The Group had US$2,197 million of unrecognised deferred tax assets relating to Australian Petroleum Resource Rent Tax (PRRT) at 30 June 2019 (2018: US$2,282 million relating to Australian PRRT), with a corresponding unrecognised deferred tax liability for income tax purposes of US$659 million (2018: US$685 million). Recognition of a deferred tax asset for PRRT depends on benefits expected to be obtained from the deduction against PRRT liabilities.
(4) | The Group had deductible temporary differences relating to mineral rights for which deferred tax assets of US$2,230 million at 30 June 2019 (2018: US$2,263 million) had not been recognised because it is not probable that future capital gains will be available, against which the Group can utilise the benefits. The deductible temporary differences do not expire under current tax legislation.
(5) | The Group had other deductible temporary differences for which deferred tax assets of US$412 million at 30 June 2019 (2018: US$437 million) had not been recognised because it is not probable that future taxable profits will be available against which the Group can utilise the benefits. The deductible temporary differences do not expire under current tax legislation.
