You set up your regression in JMP as a nominal logistic, so you are regressing the generalized logits against the linear predictor. That model means that if there are 7 levels in your response, then there will be 6 logits and 6 sets of parameters, one set for each logit. Your linear predictor is a combination of categorical factors except for Firm Size. That parameterization further expands the number of estimates within each set.
Can you use the Effect Likelihood Ratio Tests to assess the significance of the individual terms in the model? This table appears below the Parameter Estimates table.
