williams406, believe CET sold 20% or so back to PROC few years ago and believe they/CET or PROC stated would like to sell back more or all ( believe wilmot on PROC board).
believe PROC would like to buy back , but they also have their eye on SAFT( see their portfolio https://www.sec.gov/Archives/edgar/data/1496228/000156761918005956/xslForm13F_X01/form13fInfoTable.xml ) which is big in same state(MASS) that PROC started in.
as Spekulatius stated they have a lot of deferred taxes therefore that is why i like it in my retirement plans.
Also how does on reply to another with the pretty little bold print. know I am looking a little obtuse here.
