In a similar way when assets fall below other levels, credit migration to lower credit ratings will occur too. Asset returns are normally distributed.

DEFINITION of Rating. A rating is an assessment tool assigned by an analyst or rating agency to a stock or bond. The rating assigned indicates the stock or bond's level of investment opportunity. For a stock, an analyst may assign a buy, hold or sell rating and an explanation of why they recommend this action for the stock. Second, the transitions are generally non-Markovian, meaning that the rating migration in the future depends not only on the current state, but also on the behavior in the past. Figure 2 compares the cumulative probability of downgrading for newly issued Ba issuers, those downgraded, and those upgraded. The probability of downgrading further is risk migration analysis (migration probability of the bond rating). The bond rating is an important indicator to evaluate a company’s credit quality, as well as their default probability. A change in a company’s rating reflects the credit quality of that company, either improved (upgrade) or deteriorating (downgrade).
