The company also notes there were no disagreements or reportable events with YCM, and that it had not previously consulted Assentsure on accounting or audit opinions. This framing presents the change as an orderly auditor rotation rather than a response to disclosed accounting disputes.

independent registered public accounting firm financial

"approved the dismissal of YCM CPA INC. as the Company’s 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 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.

disagreements regulatory

"there were no disagreements (as defined in Item 16F(a)(1)(iv) of Form 20-F)"

Form 20-F regulatory

"as defined in Item 16F(a)(1)(iv) of Form 20-F and the related instructions"

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.
