Looks like integers are not formatted with CONVFMT. Try
Code:
awk '$1 ~ /2013$/ {$13 = -9.99; for (i=2; i<=NF; i++) $i=sprintf("%6.2f", $i)}1' file

To be more efficient what is the best way to also remove lines that contain integers greater than 2013.

I was using this command separately, but would rather combine it with the above code.

Code:
awk 'substr($1,length($1)-3) <= 2013 file
