Trade receivable representing rights arising from sales and loans to employees or any other similar concept, are presented on the consolidated statement of financial position net of discounts and the allowance for expected credit losses.

Coca-Cola FEMSA has accounts receivable from The Coca-Cola Company primarily arising from the latter’s participation in advertising and promotional programs.

Because less than the 1.7% of the trade receivables is unrecoverable, the Company does not have any customers classified as “high risk” which would be eligible to have special management conditions for the credit risk. As of December 31, 2023, the Company does not have a representative group of customers directly related to the expected credit loss.

The allowance for expected credit losses is calculated with an expected losses model that recognizes the impairment losses through all the contract life. Because they are generally short-term trade receivables, the Company defined a model with a simplified expected loss focus through a parametric model. The parameters used in the model are:

In determining the recoverability of trade receivables, the Company considers any change in the credit quality of the trade receivable from the date credit was initially granted up to the end of the reporting period.

The carrying value of trade receivables approximates its fair value as of December 31, 2023 and 2022.

The Company recognizes an allowance for expected credit losses at each reporting date using a provision matrix to measure expected credit losses. The provision rates are based on days past due for groupings of various customer segments with similar credit loss patterns.

For the years ended as of December 31, 2023, 2022 and 2021, the Company had an allowance for Ps. 577, Ps. 538 and Ps. 531, respectively.
