independent directors financial

"the Company’s Board will consist of four directors ... and five independent directors"

Members of a company’s board who do not have significant business, family, or financial ties to the company and are not part of its management; they are chosen to provide impartial oversight of strategy, financial reporting, executive pay and risk. They matter to investors because independent directors act like an objective referee, helping ensure decisions favor shareholders’ long-term interests rather than insiders, which can strengthen trust and reduce the chance of mismanagement or conflicts of interest.

Corporate Governance and Nominating Committee financial

"Ms. Tengah will also serve on the Board’s Corporate Governance and Nominating Committee"

A corporate governance and nominating committee is a group of independent board members who set rules for how a company is run and choose or vet candidates for the board and senior leadership. Think of them as the company’s rulebook authors and hiring panel for its top oversight team; their choices and policies influence management accountability, risk oversight and investor confidence, so investors watch them for signs of strong leadership and transparency.

Investment Committee financial

"Ms. Tengah will also serve on the Board’s Corporate Governance and Nominating Committee and Investment Committee"

An investment committee is a small group of experienced people who set the rules and make the key decisions about what investments to buy, hold, or sell for a fund, pension, or portfolio. Think of them as the steering team that balances goals, potential returns and risk—their choices shape how much money investors are likely to gain or lose and provide consistent oversight so decisions aren’t made impulsively.

sovereign wealth fund financial

"the Brunei Investment Agency (BIA), the sovereign wealth fund of the Government of Brunei"

A sovereign wealth fund is a large savings pool managed by a country's government, created by setting aside part of the nation’s wealth—such as revenue from natural resources or budget surpluses—for future use. It functions like a national investment account, helping stabilize the economy and generate income over the long term. For investors, it represents a significant source of financial stability and potential investment opportunities in global markets.

Chartered Financial Analyst (CFA) financial

"She is a Chartered Financial Analyst (CFA) charterholder"

A chartered financial analyst (CFA) is a professional credential awarded to investment professionals who pass a series of rigorous exams and agree to a strict code of ethics. For investors, the CFA label is like a professional licence: it signals tested knowledge in analyzing investments, building and managing portfolios, and a commitment to ethical conduct, which can increase trust in someone’s investment advice or stewardship of funds.

Form 20-F regulatory

"whether the registrant files or will file annual reports under cover of Form 20-F"

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.
