Basis of consolidation
The consolidated financial statements comprise the financial statements of Luxfer Holdings PLC and its subsidiaries (the "Group") at December 31 each year. The financial statements of the subsidiaries are prepared for the same reporting year as the parent company, using consistent accounting policies. All inter-company balances and transactions, including unrealized profits arising from intra-Group transactions, have been eliminated in full.
Subsidiaries are consolidated from the date on which control is transferred to the Group and cease to be consolidated from the date on which control is transferred out of the Group.
The accounting policies which follow, set out those polices which apply in preparing the consolidated financial statements for the years ended December 31, 2015, December 31, 2016 and December 31, 2017.
