Berkshire Hathaway stands as a titan in the investment world, a conglomerate built by Warren Buffett and Charlie Munger that has delivered staggering compounded returns for decades. So b)? A) or **Class B shares (BRK.Which means for investors looking to own a piece of this empire, a unique decision awaits immediately: should you buy **Class A shares (BRK. While both represent ownership in the exact same underlying businesses—from Geico and BNSF Railway to Apple and Coca-Cola—the structural differences between the two share classes have profound implications for accessibility, voting power, tax efficiency, and estate planning Worth keeping that in mind..
The Origin Story: Why Two Classes Exist
To understand the distinction, one must look back to 1996. Berkshire’s Class A shares had appreciated to such stratospheric levels—trading well above $30,000 at the time—that they were becoming inaccessible to average investors. This high price attracted the attention of financial firms looking to create unit trusts and mutual funds that would fractionalize ownership, effectively skimming fees off Buffett’s shareholders Worth knowing..
Buffett, ever the protector of the "partner" mentality, despised the idea of intermediaries profiting from his investors. That said, his solution was to create Class B shares, initially valued at 1/30th of a Class A share. Day to day, this move democratized ownership, allowing smaller investors to buy directly without paying fees to a fund manager. In 2010, ahead of the acquisition of Burlington Northern Santa Fe, Berkshire executed a 50-for-1 split of the Class B shares, bringing the ratio to its current level: one Class A share equals 1,500 Class B shares.
Price and Accessibility: The Most Obvious Difference
The primary driver for most retail investors choosing Class B is simple arithmetic. As of recent trading, a single Class A share often trades north of $600,000, making it one of the most expensive publicly traded stocks on the planet. A single lot requires capital that exceeds the median net worth of many American households Not complicated — just consistent..
Conversely, Class B shares trade at roughly 1/1,500th of that price, typically hovering in the high $300 to low $400 range. In real terms, this lower denomination offers critical granularity. If an investor holds $10,000 worth of Class B shares and needs $2,000 for an emergency, they can sell a few shares. A Class A holder cannot sell "half a share" on the open market; they face an all-or-nothing liquidity event unless they convert to B shares first (a one-way street we will discuss later).
For dollar-cost averaging—systematically investing a fixed amount monthly—Class B is the only practical vehicle for the vast majority of participants.
Voting Rights: The Governance Gap
This is the structural difference that matters most to Buffett and the board. Class A shares carry significantly superior voting rights.
- Class A: One vote per share.
- Class B: 1/10,000th of a vote per share (effectively 1/1,500th of the economic interest but only 1/10,000th of the vote).
In practical terms, 1,500 Class B shares (economic equivalent of 1 Class A) carry only 0.15 votes. Even so, this disparity was engineered deliberately. Buffett wanted to confirm that long-term, committed capital—typically held by insiders, institutions, and high-net-worth individuals in Class A—retained control over major corporate decisions, such as mergers, acquisitions, or changes to the board of directors.
For the average investor, this difference is largely theoretical. Here's the thing — berkshire is not a target for hostile takeovers, and Buffett’s succession plan is firmly established with Greg Abel named as the future CEO. Even so, if you value the principle of having a proportional say in corporate governance, Class A is the only route.
The Conversion Feature: A One-Way Valve
A unique feature of Berkshire’s capital structure is the conversion privilege. Class A shareholders can convert their shares into Class B shares at any time (at the 1:1,500 ratio). **Class B shareholders cannot convert back into Class A Not complicated — just consistent. Practical, not theoretical..
This creates a fascinating dynamic. It acts as a "pressure release valve" for the Class A price. If Class A shares ever trade at a significant premium to the intrinsic value of 1,500 Class B shares (beyond the voting premium), rational arbitrageurs would convert A to B and sell the B shares, pushing the prices back in line And it works..
Because conversion is permanent, Class A shares carry a scarcity value. That said, the total float of Class A shares can only shrink over time as holders convert (often for estate planning or gifting purposes). This irreversibility supports a persistent, albeit small, valuation premium for Class A shares relative to the exact mathematical equivalent of Class B shares Small thing, real impact..
Liquidity and Market Mechanics
While Class A shares represent the "original" equity, Class B shares dominate daily trading volume.
- Class B (BRK.B): Included in the S&P 500 index. This mandates massive, persistent buying from index funds, ETFs, and institutional benchmark-trackers. Daily volume is typically in the millions of shares. Spreads are razor-thin (often one cent), and market depth is enormous. You can enter or exit large positions with minimal market impact.
- Class A (BRK.A): Excluded from the S&P 500 primarily due to its price (index methodologies often have price screens or weighting constraints that make a $600k+ share impractical). Volume is low—often just a few thousand shares per day. Spreads are wider in absolute dollar terms, and large orders can move the price significantly.
For an institutional investor managing billions, Class B is the only viable option for building a meaningful position quickly. For a high-net-worth individual, the illiquidity of Class A is a feature, not a bug—it discourages trading and encourages the "buy and hold forever" mentality Buffett preaches.
Tax Efficiency and Estate Planning Nuances
The conversion feature unlocks powerful estate planning strategies unavailable to Class B holders.
Because Class A shares can be converted to Class B, a holder can gift or bequeath shares in much smaller denominations. Imagine an investor owns 10 Class A shares (worth ~$6M+). They cannot easily gift "10% of a share" to a grandchild. But they can convert 1 Class A share into 1,500 Class B shares and gift 150 Class B shares (worth ~$60k) to each of ten grandchildren. This allows for precise utilization of the annual gift tax exclusion ($18,000 per recipient in 2024) and the lifetime estate tax exemption Still holds up..
What's more, upon death, assets receive a step-up in basis to the fair market value. Holding highly appreciated Class A shares until death eliminates the massive capital gains liability entirely for heirs. The ability to fragment that position into Class B shares before death (or via a trust mechanism) provides flexibility in distributing the cost basis and holding periods across multiple beneficiaries Simple as that..
Class B holders lack this fragmentation tool. If you hold 1,500 Class B shares, you cannot combine them into a single Class A share to simplify a transfer. You are stuck with the 1,500 individual lots for tracking cost basis.
The "Voting Premium" Valuation Debate
Financial theorists often debate whether Class A should trade at a premium to 1,500 Class B shares.
