(b) | Mining concessions mainly include net acquisition costs of S/15,367,000 related to coal concessions acquired through a purchase option executed from 2011 to 2013. The caption also includes some concessions acquired by the Group for exploration activities related to the cement business. |
In previous years management recognized a full impairment charge of approximately S/95,994,000, related to the total net book value of a closed zinc mining unit which includes concession costs, development costs and related facilities and equipments. From this amount, S/41,213,000 corresponds to concessions costs. According to the management’s expectation the recovery amount of this zinc mining unit is zero.
As of December 31, 2017, the Group has recognized an impairment on the brine project. As a consequence the Group wrote-off the concessions and other related assets for S/1,732,000. See note 1.2.
(c) | There were no additions under finance leases during the years 2017 and 2016. |
(d) | During 2016 the Group capitalized borrowing costs for S/3,309,000 mainly related with the expansion of the cement plant located in Piura. The rate used to determine the amount of borrowings costs eligible for capitalization was approximately 5.00 percent as of December 31, 2016, which is the effective rate of the only borrowing the Group has as of such date. The amount of borrowing costs eligible for capitalization is determined by applying the capitalization rate to the capital expenditures incurred on qualifying assets. Since September 2015, a part of this project is operating. In February 2016, a significant part of this cement plant was launched to operations, and the Group ceased to capitalize borrowing costs. |
(e) | The Group has assessed the recoverable amount of its remnant long-term assets and did not find an impairment of these assets as of December 31, 2017. |
(f) | Work in progress included in property, plant and equipment as of December 31, 2017 amounted to S/42,137,000 (2016: S/183,918,000) and is mainly related to complementary facilities of the cement plants. |
(g) | As of December 31, 2017, the Group maintains accounts payable related to the acquisition of property, plant and equipment totaling S/5,368,000 (S/7,870,000 as of December 31, 2016). |
