Impairment charges on receivables are recognised in property operating costs. Risk management In risk management, the emphasis is on ensuring compliance with the strategy and, building on this, on identifying and assessing risks and opportunities, as well as on the fundamental decision to manage these risks. Risk management ensures that risks are identified at an early stage and can then be evaluated, communicated promptly and mitigated. Risk analysis involves the identification and analysis of factors that may jeopardise the achievement of goals.
