5. Question 5 Based on the percentages from Question 2, it is clear that BAC has been lagging behind NAC in terms of net profit margin, specially after it installed the new smelter However, one would have to consider that those figures may not be truly representative of the actual situation and could just be bloated figures Based on our estimation the actual profit/sales percentage would be closer to 7.9 than the calculated value Since it has been mentioned that the other aluminium firms practice similar accounting practices, one could assume that the figures for these other companies could also just be bloated figures Caution is advised in investing in such firms. A clearer understanding of these companies’ account books would be mandatory
