Caldrin SA sells ski equipment; according to the case, more than 60% of its annual revenue is earned in the fourth and first quarters. In the second quarter, the finance director proposes to recognise as revenue a quarter of the estimated annual revenue, that is EUR 2,500,000 out of EUR 10,000,000, "so that the quarter looks like an average year". Sales actually made in the quarter are EUR 900,000 (case data). What must Caldrin SA do?
