The Name's Bond: Lam Research Bond and Altman Z-Score
All about Raison's bonds

In a series of publications dedicated to bonds in our portfolio we continue explaining how and why we select them. In the previous publication, we discussed credit ratings using the example of Oceaneering International, Inc., an engineering products and services company.
Today, we’ll explain the Altman Z-Score and why it’s important, using Lam Research bonds as an example.
What is the Altman Z-Score?
The Altman Z-Score is a model designed to predict a company’s bankruptcy risk over the next few years. It’s calculated using a formula that factors in profitability, leverage, liquidity, solvency and activity.
A high Altman Z-Score indicates a company’s stability, while a low score points to an elevated risk of bankruptcy. A score above 3 suggests solid financial health, while a score near or below zero indicates a high likelihood of bankruptcy.
The Altman Z-Score is an essential part of our bond analysis. It’s an important indicator of an issuer’s stability that cannot be overlooked.
