The centroid plot illustrated in Fig. 2 clearly shows that all three
firm groups are clustered upon three different levels across the 10
IDR factors. According to Table 4, Cluster 1 (n=9) consists of centroid
values ranging from 3.54 to 4.52, with the majority being greater than
4.00, hence labelled very high IDR (VIDR). Cluster 2 (n=25) was labelled
high IDR (HIDR) as indicated by its centroid values ranging
from 3.16 to 4.13, with most values being close to 4.00. Lastly,
