The default probabilities produced by the KRIS service include both the best practice reduced form default probabilities and the older and less accurate Merton model default probabilities. In this note, we use the KRIS version 6.0 reduced form default probabilities, the newest and most accurate model in the KRIS default models framework. The chart below shows the history of the 1-month (in red), 1-year (in blue), 5-year (in orange), and 10-year (in green) default probabilities for Takata:
Vehicles made by 14 different automakers have been recalled in July 2016 to replace frontal airbags on the driver’s side or passenger’s side, or both; the airbags, made by major parts supplier Takata, were mostly installed in cars from model year 2002 through 2015. Some of those airbags could deploy explosively, injuring or even killing car occupants. At the heart of the problem is the airbag’s inflator, a metal cartridge loaded with propellant wafers, which in some cases has ignited with explosive force. If the inflator housing ruptures in a crash, metal shards from the airbag can be sprayed throughout the passenger cabin—a potentially disastrous outcome from a supposedly life-saving device.

In Kamakura Corporation’s popular troubled company index, a firm is considered “troubled” if its default probability exceeds one percent. The box on the left hand side of the graph above shows that the 1-year default probability of Takata exceeded 15.00% in July 2016, consequent to the airbag recall story hitting the news then. However, it is illuminating to note that a full 10 months before this event, Takata was showing a deterioration in its creditworthiness, starting September 2015, where all four term structure points on the default curve moved up from 2-3% to well over 6%. For a fixed income investor, this is tremendous early warning, and highlights exit options well before a default event. This makes for particularly interesting reading in conjunction with the airbags recall event, as it is evident that even before the troubling news on the airbags were aired, the organization was in troubled waters. Whilst the recall story outlined a specific problem with the company, the Kamakura Default Probabilities showcased the increasing risk on account of the changing market landscape. It is debatable whether the organization would have had such a surge in its default probabilities had it not been for the unfortunate news relating to its airbags, but it cannot be disputed that Takata’s troubles pre-dated this problem.
Another important metric in KRIS is the cumulative default probability for the issuer. On September 30, 2015, the cumulative 10-year default probability for Takata was a high 3%. This metric was a warning signal provided by KRIS a full twelve months before its troubles.
A third analytic in the KRIS portfolio of outputs is the impact of macro factors on the company’s creditworthiness, and this represents a statistical relationship between key risk and macro factors and the performance of the company. It can be clearly seen from the graph below that the macroeconomic factors influencing Japan plays a major role in explaining the probability of default movements of Takata, and has an accuracy of close to 92%. Furthermore, it can be seen clearly from the graphic that both oil prices and the USD JPY exchange rates are negatively correlated with the probability of default.
Another indicator that is very valuable as an early warning signal is a comparison to the industry peer group, which in the case of Takata is the Autos & Components peer group. It can be seen clearly in the graph below that Takata’s one-year default probability moved to well above the median, and indeed higher than 2 standard deviations above the median, in late 2015. This is another warning, more than a year before default, to exit from any holdings of Takata.
The KRIS default probability models are benchmarked on more than two million observations of firms of all types. The total number of defaults used in the current version 6.0 models is more than 2,600. The unparalleled volume of data and the research insights of Kamakura’s Managing Director Prof. Robert Jarrow make the KRIS default probability service the most accurate early warning credit risk assessment indicator framework available. That is one of the reasons why Credit Magazine named both KRIS and the Kamakura Risk Manager Software package “Innovations of the Year”.
