Differences in working capital also cause impact on cash flow from operating activities. Same results are found similarly in analyzing the SEC and the Group. Moreover, regarding the purpose the capital, SEC evidently shows higher weights in cash outflows from investment activities than in property, plant and equipment. The difference mainly lies in the cross-investments between SEC and Samsung Group. On the other hand, based on the computation of financial ratios, SEC benefits from Samsung Group's integrated supply chains in comparison with AUO and PSC, especially in terms of account receivables and inventories. However, the same advantages are not shown in account payables conversely. It is inferred that SEC supports Samsung Group through giving looser credits. To sum up, as far as cash flows are concerned, SEC is capable of operating with sufficient working capital because of diversification and cross-investment within the Group.
