Issue using awk to print min values for unique ids

I am using the following script to search for and print minimum values for each individual Fields (3-14) for each unique id (Field 1). But when the field contains a "-99.99" ( I am ignoring "-99.99") and when the minimum value is the first line of a new id (Field 1), the output does not print Field 2, it leave a blank space. Any ideas on how to correct this?

The below snipit is looking for the min value in field 12 only.

Code:
awk ' /-99.99/ {next} {if (a[$1] == "") a[$1] = $12; if (a[$1] > $12) {a[$1]=$12" " $2} } END { for (i in a) { print i, a[i]} }'

Input file sample
Code:
01001   012017  10.64   3.96    4.45    3.48    9.58    10.76   4.44    5.03    2.78    1.45    1.26    3.24
01001   012018  3.94    6.18    4.47    4.79    11.07   3.01    4.27    6.37    6.48    4.52    6.16    9.95
01001   012019  6.77    3.79    3.96    -99.99  -99.99  -99.99  -99.99  -99.99  -99.99  -99.99  -99.99  -99.99
01003   011895  6.46    3.53    6.69    4.63    3.54    11.71   7.64    8.02    2.45    3.21    1.35    4.05
01003   011896  3.80    5.88    5.63    2.45    2.83    6.98    5.24    5.60    2.90    5.38    4.09    2.45

Current Output
Code:
01001   1.45 
01003   3.21  011895

Expected Output
Code:
01001   1.45  012017 
01003   3.21  011895
