The analysis tea idntiied ovr 7 difernt~otential, root cause failure modes for the de-lmnto n
has narrowed this list to a handfulof remaining failure modes. Although the analysis-is not c6mplete;, th;.e remaining variables appear to point toward the interplay between several factors.
We expect to:.have this review comp eted by the end ofJianuary, 2010.
The Company has a:lso:deveLoped,*aworkplan to complete the r 1pairstothe building.structure.
We are mobilizing our effo rts,to :b.egin therepairs, which we expect to commence once we have further insight from our root cause a~nalysis.
