Sept 30 (Reuters) - World's largest catering firm Compass Group expects annual organic revenue to fall by 19% and said it would impair about 100 million pounds ($128.30 million) worth of assets as it reviews its contracts to deal with the blow from the COVID-19 pandemic.

The UK-based company, which employs around 600,000 people and served billions of meals across 45 countries before the pandemic struck, said performance across its markets have seen an improvement as schools and businesses start reopening.
