Philippine corporate law distinguishes among various types of stock corporations to balance flexibility in private enterprise with the need for public accountability and investor protection. The Revised Corporation Code of the Philippines (Republic Act No. 11232, or RCC), which took effect on 20 February 2019, and the Securities Regulation Code (Republic Act No. 8799, or SRC) form the primary legal framework governing these distinctions. While the RCC modernized the rules on corporate formation, governance, and dissolution, the SRC imposes heightened regulatory standards on corporations that engage the investing public. Within this framework, an “open corporation” (sometimes referred to as a non-close corporation) and a “publicly held corporation” represent two related but distinct categories of stock corporations. All publicly held corporations are open corporations, yet the reverse is not true. The classification carries significant consequences for formation, management, share transfer, regulatory compliance, disclosure obligations, capital-raising options, and overall operational freedom.

Legal Framework

The RCC governs the general organization and operation of all domestic corporations. Title III, Chapter III (Sections 95–100) specifically regulates close corporations and, by necessary implication, defines open corporations as all other stock corporations. The SRC, administered by the Securities and Exchange Commission (SEC), regulates the offer and sale of securities to the public and imposes continuous reporting and governance obligations on publicly held entities. Additional rules come from the Philippine Stock Exchange (PSE) Listing and Disclosure Rules (for listed companies), the SEC Code of Corporate Governance for Publicly-Listed Companies, and related issuances. The National Internal Revenue Code (NIRC) and Bangko Sentral ng Pilipinas regulations may also create ancillary distinctions in taxation and financial reporting.

Definition and Characteristics of an Open Corporation

An open corporation is any stock corporation that does not qualify as a close corporation under Section 95 of the RCC. To be classified as close, the articles of incorporation (AOI) must expressly provide that:

All issued shares of stock are held by not more than twenty (20) persons;
All issued shares are subject to one or more restrictions on transfer; and
The corporation is not listed on any stock exchange or its shares are not publicly offered.

If the AOI does not contain these three provisions, or if any one of them is absent or later ceases to apply, the corporation is treated as open. Open corporations therefore include:

Private companies with more than twenty shareholders;
Corporations whose shares are freely transferable without the mandatory restrictions required for close corporations;
Corporations that have not elected close-corporation status even if they could qualify.

Key features of open corporations include:

Unlimited potential number of shareholders;
Standard corporate governance rules under the RCC: management vested in a board of directors elected by shareholders, formal board and stockholder meetings, and quorum and voting requirements;
Freer transferability of shares, subject only to general restrictions in the AOI, bylaws, or securities laws;
Eligibility to conduct private placements or, subject to SRC approval, public offerings of securities;
Applicability of the general provisions of the RCC on pre-emptive rights, appraisal rights, derivative suits, and fiduciary duties of directors and officers.

Open corporations follow the default corporate model: shareholders own, the board manages, and officers execute day-to-day operations. They enjoy greater structural flexibility than close corporations in some respects (no mandatory transfer restrictions) but lack the partnership-like informality that close corporations may adopt.

Definition and Characteristics of a Publicly Held Corporation

A publicly held corporation—also called a public company or, when listed, a publicly listed company—is a stock corporation whose equity securities are held by a broad segment of the investing public. Under the SRC and SEC rules, a corporation becomes “publicly held” when it meets either of the following triggers:

It has a class of equity securities listed on the Philippine Stock Exchange (or any other organized securities market); or
It has total assets of at least Fifty Million Pesos (P50,000,000.00) and two hundred (200) or more stockholders each holding at least one hundred (100) shares of a class of equity security (the “200-or-more shareholder rule”).

Publicly held corporations therefore encompass both:

Publicly listed corporations (those whose shares are traded on the PSE, subject to minimum public float requirements—typically at least 10–20% of outstanding shares depending on sector—and stringent listing rules); and
Reporting issuers or non-listed public companies that have crossed the 200-shareholder threshold even without listing.

Key features include:

Wide public ownership and liquidity of shares;
Heightened regulatory oversight by the SEC and, if listed, the PSE;
Mandatory compliance with enhanced corporate governance standards, including independent directors (at least three or one-third of the board, whichever is higher), board committees (audit, nomination, compensation, and corporate governance), and risk management systems;
Continuous disclosure obligations under SRC Rule 17 and PSE rules.

Key Similarities

Both open and publicly held corporations are stock corporations organized under the RCC. They share:

The requirement of SEC registration and issuance of a Certificate of Incorporation;
Basic capital structure rules (authorized capital stock, par or no-par shares, minimum paid-up capital of P5,000 for most corporations);
Fiduciary duties of directors and officers (duty of care, loyalty, and good faith);
Shareholder rights (voting, inspection, dividends when declared, appraisal rights);
Liability limited to the amount of unpaid subscriptions (corporate veil protection);
Subjection to general RCC provisions on mergers, consolidations, dissolution, and rehabilitation.

All publicly held corporations necessarily satisfy the criteria for open corporations because they either exceed the twenty-shareholder limit or have shares that are publicly offered or listed—both of which disqualify them from close-corporation status.

Key Differences

The distinctions between an open corporation and a publicly held corporation are best understood across several dimensions:

Shareholder Base and Ownership Structure
An open corporation may have any number of shareholders greater than twenty or may maintain a moderate investor base without triggering the SRC’s 200-shareholder rule. A publicly held corporation, by definition, has a broad public ownership base—either through listing or the 200-or-more shareholder threshold. Publicly held corporations are therefore always open, but many open corporations remain private or semi-private.
Share Transferability and Liquidity
Shares in an open corporation are transferable subject only to the corporation’s AOI, bylaws, or contractual agreements. Liquidity is limited unless the corporation undertakes a public offering. In a publicly held corporation, shares (especially listed ones) enjoy high liquidity through organized trading platforms, subject to market rules, lock-up periods for new issues, and insider trading restrictions.
Regulatory Oversight and Compliance Burden
Open (non-public) corporations are primarily regulated by the RCC and basic SEC requirements (annual General Information Sheet, audited financial statements). Publicly held corporations face layered regulation: the RCC plus the full SRC regime, including registration of securities offerings, continuous reportorial requirements (SEC Forms 17-A annual, 17-Q quarterly, 17-C current reports on material events), beneficial ownership disclosures (SEC Form 23-A/B), and proxy solicitation rules. Listed companies additionally comply with PSE disclosure and corporate governance rules.
Corporate Governance Requirements
Open corporations follow standard RCC board structures. Publicly held corporations must adopt the SEC’s Code of Corporate Governance, mandating independent directors, board diversity, risk oversight, and internal controls. Audit committees and related-party transaction policies are stricter for public companies.
Capital Raising and Financing Options
Open corporations may raise funds through private equity placements, bank loans, or retained earnings. Publicly held corporations can access public capital markets via initial public offerings (IPOs), follow-on offerings, or debt securities, but must comply with prospectus requirements, underwriter due diligence, and minimum public float rules.
Disclosure and Transparency Obligations
Open corporations maintain greater operational privacy. Publicly held corporations operate under a regime of full and timely disclosure to protect minority investors and market integrity, including real-time disclosure of material information that could affect share prices.
Taxation and Related Implications
Both are subject to the regular corporate income tax rate under the NIRC (currently 25% or 20% for domestic corporations with net taxable income not exceeding certain thresholds, subject to periodic adjustments). However, publicly listed shares sold through the PSE incur a stock transaction tax of 0.6% on gross selling price instead of the regular capital gains tax applicable to unlisted shares. Publicly held corporations may also face additional scrutiny in transfer pricing, withholding taxes on dividends to non-residents, and minimum corporate income tax (MCIT) compliance reporting.
Management Flexibility and Minority Protection
Open corporations enjoy the standard separation of ownership and control. Publicly held corporations provide enhanced minority shareholder protections through mandatory tender offer rules (when ownership reaches 35% or 50%), appraisal rights in fundamental changes, and derivative suit facilitation.

Formation, Amendment, and Transition

Any stock corporation begins as open unless its AOI expressly elects close-corporation status and meets the three statutory conditions. An open corporation may become publicly held by:

Conducting an IPO and listing on the PSE; or
Reaching the 200-shareholder threshold through private placements or share issuances.

Conversely, a publicly held corporation cannot revert to non-public status without delisting (subject to PSE and SEC approval) and reducing its shareholder base below the threshold, which is rare and heavily regulated. An open corporation may amend its AOI to become a close corporation only if it satisfies the three conditions and obtains the necessary shareholder vote (usually two-thirds).

Practical Implications and Examples

An open but non-public corporation might include a medium-sized family enterprise with fifty shareholders or a joint-venture company with institutional investors that has not yet reached public-company thresholds. These entities prioritize control and privacy. Publicly held corporations include blue-chip listed companies such as those in the PSE’s main index (e.g., banks, conglomerates, utilities) that rely on public capital markets for expansion. The choice between remaining a private open corporation or becoming publicly held involves trade-offs: greater access to capital and prestige versus higher compliance costs (legal, accounting, audit, and governance expenses), loss of privacy, and exposure to market volatility and activist shareholders.

Regulatory agencies involved are the SEC (incorporation, registration statements, enforcement) and the PSE (listing, trading, and market surveillance). Violations of SRC disclosure rules may result in fines, suspension of trading, or director/officer disqualification.

In summary, the distinction between an open corporation and a publicly held corporation lies primarily in the degree of public involvement and the consequent regulatory intensity. Open corporations provide the foundational flexibility for most Philippine businesses, while publicly held corporations represent the subset that has crossed into the public capital market sphere, triggering comprehensive investor-protection mechanisms under the SRC. Understanding these differences is essential for entrepreneurs, investors, and counsel in structuring entities that align with strategic, financial, and compliance objectives under Philippine law.
