If you use D&B's free CreditSignal® service to monitor your company's scores and ratings like I do, you probably recognize the <—> arrows shown below. Most people would think those arrows (and the words "No Change") would indicate your scores are "unchanged" — but that's not always the case.
In the case of the Paydex® score above — if you thought the "unchanged" arrows indicate that score has not changed since 11/07/2017, you would be correct. Even though the CreditSignal doesn't allow us to see the actual Paydex® score, the fact that it hasn't changed up or down in over a year is good — because a stable Paydex® score is an indication of a stable business.
With regards to the Delinquency Predictor Class, however, the "unchanged" indicator is misleading. We know this because the date to the right of the arrows is a more recent date than what was showing just the day before.
To understand what is really happening here, you need to realize that the Delinquency Predictor Class (shown in the image) is NOT the same thing as the Delinquency Predictor Score (which is not shown).
While the Delinquency Predictor Score ranges from 100 to 670, with higher scores indicating lower risk, the Class (which is what is shown in the CreditSignal®,) is factored incrementally on a scale of 1 to 5, with lower numbers indicating lower risk.
