Understanding the Meaning of "Rayman":
The term "Rayman" can refer to two distinct concepts:
<li><strong>Lehman Brothers:</strong> Lehman Brothers Holdings was once a globally renowned full-service, diversified investment bank. It offered a wide range of financial services to various clients, including corporations, institutions, governments, and individual investors, catering to their diverse financial needs.</li>

<li><strong>Lehman Moment:</strong> This phrase specifically refers to the pivotal moment in 2008 when Lehman Brothers, then the fourth-largest investment bank in the United States, filed for bankruptcy protection after failed acquisition negotiations. This event, akin to a domino effect, triggered a global financial crisis that had far-reaching consequences on the world economy.</li>
The collapse of Lehman Brothers not only marked the climax of the subprime mortgage crisis but also became an iconic symbol in the history of modern financial crises. It prompted deep introspection into the stability of financial markets and the adequacy of regulatory measures.
