The market sales for January-June are attached. The exchange rates for 2013 and 2014 have been updated. This suggested version makes a few assumptions - that you are referring to two different years when you say 2013 and 2014 (as opposed to the financial year from mid 2013-mid-2014), and that when you said 'is changed', you meant that you have changed it (updated it) to reflect the correct value.
