MDX query that replaces hard coded year with current year, but if prior to January 15th use previous year

How does one write a MDX query that replaces hard coded year with current year, but if prior to January 15th use previous year. Here is what I have below


SELECT NON EMPTY {
[Measures].[TCE],
[Measures].[Voyage Count],
[Measures].[PnL],
[Measures].[Voyage Result],
[Measures].[Net Days] } ON COLUMNS,
 NON EMPTY {
 ([Voyage].[Charterer].[Charterer].ALLMEMBERS ) }
 DIMENSION PROPERTIES MEMBER_CAPTION, MEMBER_UNIQUE_NAME ON ROWS
 FROM ( SELECT ( [Top 10 Charterers] )
 ON COLUMNS FROM ( SELECT ( { [Date].[Year].&[2014] } )
 ON COLUMNS FROM [cubeVoyageResults]))
 WHERE (
   [Date].[Year].&[2014]
 )
 CELL PROPERTIES VALUE, BACK_COLOR, FORE_COLOR, FORMATTED_VALUE, FORMAT_STRING, FONT_NAME, FONT_SIZE, FONT_FLAGS

I don't use MDX, so all I'm attempting for you are some pointers (sorry, others may supply the bits I can't)

a. the function NOW() supplies the system date and you can then use YEAR() to extract just that part of the date.

This MS support article explains it see the example below
-- The First Calculated member is the value of NOW()
WITH  MEMBER [Measures].[Full Date] as 'NOW()'
-- The Second Calculated Member is the Day part of the first calculated member.
MEMBER [Measures].[What Day] as 'DAY([Full Date])'
-- The Third Calculated Member is the Month part of the first calculated member.
MEMBER [Measures].[What Month] as 'MONTH([Full Date])'
-- The Fourth Calculated Member is the Year part of the first calculated member.
Member [Measures].[What Year] as 'YEAR([Full Date])'
SELECT
   {[Full Date],[What Day],[What Month],[What Year]} ON COLUMNS
FROM Sales

b. for the wanted branch regarding the 15th of January you could use IIF()

hope this is a little helpful.
