Lines a company doesn't report are omitted. About these numbers

Going concern

Affirmed

“The directors have prepared the financial statements on the going concern basis which assumes that the Company will continue in operational existence for twelve months from the date of approval of these financial statements. The directors are confident that current cash and intercompany financing arrangements and the quality of its existing asset portfolio will provide sufficient cash resources for the Company to continue as a going concern. The directors are in receipt of a letter from ONE-Dyas B.V., indicating that financial support will be made available to meet the Company's liabilities as and when they fall due, for a period of 12 months from the date of approval of the balance sheet. The directors have considered the financial position of the parent and concluded it is capable of providing support.”
