independent registered public accounting firm financial

"appointed CHI-LLTC as its independent registered public accounting firm"

An independent registered public accounting firm is an outside accounting company officially registered with the government regulator to examine and report on a public company's financial records and controls. Investors treat its reports like an impartial inspector’s certificate — they add credibility to financial statements, help spot errors or misleading claims, and reduce the risk that shareholders are relying on unchecked or biased numbers.

reportable events regulatory

"there were no “reportable events” as that term is described in Item 16F(a)(1)(v) of Form 20-F"

Reportable events are significant incidents or changes a company is legally required to disclose to regulators and the public, such as major safety problems, legal actions, financial irregularities, or management changes. They matter to investors because these events can alter a company’s risk profile or future performance, much like a dashboard warning light signals a problem that could affect a car’s safety or reliability. Timely disclosure helps investors make informed decisions and maintain market fairness.

material weaknesses financial

"other than the material weaknesses reported by management in the annual report on Form 20-F"

Material weaknesses are significant flaws in a company’s systems for ensuring its financial reports are accurate and reliable. Like a broken lock on a safe, they increase the chance that financial statements contain big errors or omissions, which can mislead investors about performance and risk; discovering one often raises questions about management oversight, may lead to restated results, and can affect investor confidence and a company’s valuation.

Form 20-F regulatory

"annual report on Form 20-F for the fiscal year ended December 31, 2024"

Form 20-F is the standardized annual disclosure that non-U.S. companies must file with the U.S. securities regulator when their shares are traded in the U.S.; it contains audited financial statements, a plain-language description of the business, management discussion, governance details and key risk factors. It matters to investors because it provides a consistent, comparable company “report card” and rulebook, helping buyers assess financial health, governance and risks before investing.
