Trade and Other Receivables of the Group are composed of the following:


	2021			2020
Trade receivables		179,199			67,553
Loss allowance		(322	)		(341	)
Trade receivables net		178,877			67,212
Advances and other receivables		12,089			5,573
		190,966			72,785

Trade Receivables correspond to uncollateralized gross amounts due from acquirers, processors, merchants and preferred suppliers for services performed that will be collected in less than one year, so they are classified as current. No financial assets are past due except for some trade receivables. All Trade and other receivables are categorized in “normal” credit risk rating ("normal" credit risk rating comprises financial assets to which significant increase in credit risk has not occurred since initial recognition).

The following table presents the evolution of the loss allowance:


	2021			2020
Opening book value as at January 1		(341	)		(807	)
Increase in loss allowance for trade receivables		(33	)		(232	)
Reversals for decrease in loss rate		52			698
Total as at December 31		(322	)		(341	)
Net impairment (loss)/gain on financial assets(i)		(33	)		808

As disclosed in Note 2.5 Financial instruments-initial recognition and subsequent measurement, the Group applies the simplified approach to determine expected credit losses on trade receivables.

To measure the expected credit losses, trade and other receivables have been grouped based on shared credit risk characteristics and the days past due (only 0-30 past due bucket as of December 31st, 2021 and 2020 because there are no other material buckets of the outstanding receivables).

The expected loss rates are based on the payment profiles of debtors over a period of 36 months before year end and the corresponding historical credit losses experienced within this period. The historical loss rate is adjusted to reflect current and forward-looking information on credit risk ratings of the countries in which the Group sells its services which affects the ability of the debtors to settle the receivables. On that basis, the expected credit loss rate of the 0-30 past due bucket was determined at 0.4% (0.5% in the year ended December 31, 2020).

For further information refer to Note 30: Financial risk management - Impairment of financial assets.

Advances and other receivables include payments made in advance as well as tax credits.
