It appears that you have one ( too many:

FROM 
     (
      (
       (IDX_FS LEFT JOIN DATA_BS ON IDX_FS.CUSIP = DATA_BS.CUSIP) 
       LEFT JOIN DATA_Footnotes ON IDX_FS.CUSIP = DATA_Footnotes.CUSIP
      ) 
      LEFT JOIN DATA_IS ON IDX_FS.CUSIP = DATA_IS.CUSIP
     ) 
     LEFT JOIN DATA_SP ON IDX_FS.CUSIP = DATA_SP.CUSIP AND 
     ( -- This is unmatched
      (
       (DATA_BS LEFT JOIN DATA_IS ON DATA_BS.CUSIP = DATA_IS.CUSIP AND DATA_BS.4DTYR = DATA_IS.4DTYR)     
       LEFT JOIN DATA_SP ON DATA_BS.CUSIP = DATA_SP.CUSIP AND DATA_BS.4DTYR = DATA_SP.4DTYR
      ) 
      LEFT JOIN DATA_Footnotes.4DTYR ON DATA_BS.CUSIP = DATA_Footnotes.CUSIP AND DATA_BS.4DTYR = DATA_Footnotes.4DTYR
     -- A ) here perhaps?
