DATEPART(year,"Sent to Auditor") AS Y_A,
DATEPART(WK,"Sent to Trustees") AS W_T,
MAX(CASE WHEN DATEPART(WEEK,"Sent to Auditor" ) = DATEPART(WEEK, DATEADD(DAY, -1, DATEADD(YEAR, DATEDIFF(YEAR, 0, "Sent to Auditor") + 1, 0))) THEN DATEADD(DAY, -1, DATEADD(YEAR, DATEDIFF(YEAR, 0, "Sent to Auditor") + 1, 0))
