Sales, retirements and other movements in 2017 include sales of interests in Canada, the UK and Gabon. In Canada, Shell sold its 60% interest in the Athabasca Oil Sands Project (AOSP) and its in-situ and undeveloped oil sands interests for a consideration in cash and shares in Canadian Natural Resources Limited, reported in investments in securities (see Note 10). Separately, Shell acquired a 50% controlling interest in Marathon Oil Canada Corporation, which has a 20% interest in the AOSP.
The carrying amount at December 31, 2017, included $42,121 million (2016: $45,396 million) of assets under construction. This amount excludes exploration and evaluation assets. The carrying amount at December 31, 2017, also included $986 million of assets classified as held for sale (2016: $282 million, as revised).
The carrying amount of exploration and production assets at December 31, 2017, included rights and concessions in respect of proved and unproved properties of $14,839 million (2016: $15,610 million). Exploration and evaluation assets principally comprise rights and concessions in respect of unproved properties and capitalised exploration drilling costs.
The carrying amount of assets at December 31, 2017, for which an alternative reserves base was applied in the calculation of the depreciation charge (see Note 2), was $18,115 million (2016: $14,784 million). If no alternative reserves base had been used, the pre-tax depreciation charge for the year ended December 31, 2017, would have been $5,558 million higher (2016: $9,181 million, 2015: $1,022 million).
Contractual commitments for the purchase of property, plant and equipment at December 31, 2017, amounted to $4,504 million (2016: $4,825 million). In addition, Shell has other commitments for future expenditure that, when incurred, are also expected to be recognised as additions to property, plant and equipment, such as the majority of operating lease payments in respect of drilling and ancillary equipment (see Note 14).

[A] Presented by segment in Note 4, together with impairment losses and reversals in respect of intangible assets.
Impairment losses in 2017 were mainly in Upstream, and principally related to the disposal of interests in Canada and interests in Ireland classified as held for sale. Impairment losses in 2016 were mainly triggered by asset performance, disposals and project cancellations. They related primarily in Upstream to shale and deep-water properties in North and South America and in Downstream to disposals and assets held for sale in the refining portfolio. Impairment losses in 2015 were principally in Upstream related to North American shale properties, following revisions to Shell’s long-term oil and gas price outlook, and to cancelled projects in Alaska and Carmon Creek in Canada.
For impairment testing purposes, the respective carrying amounts of property, plant and equipment and intangible assets were compared with their value in use. Cash flow projections used in the determination of value in use were made using management’s forecasts of commodity prices, market supply and demand, product margins and expected production volumes (see Note 2). These cash flows were adjusted for the risks specific to the assets, and therefore these risks were not included in the determination of the discount rate applied. The nominal pre-tax rate applied in 2017 was 6% (2016: 6%; 2015: 6%).
Oil and gas price assumptions applied for impairment testing are reviewed and, where necessary, adjusted on a periodic basis. Reviews include comparison with available market data and forecasts that reflect developments in demand such as global economic growth, technology efficiency, policy measures and, in supply, consideration of investment and resource potential, cost of development of new supply, and behaviour of major resource holders. The near-term commodity price assumptions applied in impairment testing in 2017 were as follows:
