what does the phrase below mean? i don not understand it?

The Group may be exposed to losses if critical accounting judgements and estimates are subsequently found to be incorrect, which may adversely impact the Group's reputation, and financial performance and position.

Preparation of the Group's financial statements requires management to make estimates and assumptions and to exercise judgement in applying relevant accounting policies, each of which may directly impact the reported amounts of assets, liabilities, income and expenses. Some areas involving a higher degree of judgement, or where assumptions are significant to the financial statements, include the estimates used in the calculation of provisions (including those pertaining to conduct-related matters), the valuation of goodwill and intangible assets, and the fair value of financial instruments.

If the judgements, estimates and assumptions used by the Group in preparing consolidated financial statements are subsequently found to be incorrect, there could be a significant loss to the Group beyond that anticipated or provided for, which may adversely impact the Group's reputation, and financial performance and position.
