Based on my view, OD% should be around 2.5% given that small and medium customers keep more cash with them due to uncertainty of political situation.
Moreover, DD in 1Q14 may be increased around 1.5 day or closed at 62.5 days (Plan 61 days). An increase in DD result from less mix of short credit term customers sales by telesales, again this is pertaining to low demand which effected from political situation.
For cash flow, it is potentially that T/O and Debtor balance will lower than Plan in 1Q14 but Cash can be delivered as plan or even better. This is because of lower cash from operation can be offset with less sunk cost in Debtor investment.
Hope this help.
