The fair value of the short-term receivables approximates their carrying amount due to their short-term maturities. The non-current portion mainly comprises non-financial assets such as advances to suppliers and fiscal credits.

The maximum exposure to credit risk at the reporting date is the carrying amounts of each class of above-mentioned other receivables. The Group does not demand guarantees.

Guarantee deposits

Guarantee deposits are the funds retained by customers for work contracts assumed basically by the subsidiary GyM S.A.

This Sale and Purchase Contract was rightfully terminated due to the impossibility of executing its terms and conditions since it became impossible to install proper potable water and sewerage services for the housing units that were to be developed within the term limit established in the Contract. As a consequence, and in accordance with the provisions of Civil Code 1372, the parties are obliged to fully reimburse the executed benefits to date, which results in the reimbursement of S/22 million by the Ministry of Housing and S/5.2 million by the Fondo Mi Vivienda to Viva GyM.

Includes guarantee accounts for the credit agreement subscribed between the Company and Credit Suisse AG amounting to S/28 million, as reserve for the payment of interest; and S/11 million from Viva GyM S.A. for bank guarantee.
