股本发行与回购

Equity Issuance and Retirement

Introduction

Introduction

1999 年,有人请我去见一家盈利科技公司的首席执行官,这家公司在 1990 年代增长迅猛,股价表现优异。他当时陷入困境,想找我聊聊。这家公司一直慷慨地发放股票薪酬,管理团队曾向金融界承诺,将用回购股票来抵消股本发行,以保持流通股数量大致持平。

In 1999, I was asked to meet with the chief executive officer (CEO) of a profitable technology company that had grown rapidly and seen excellent share price gains in the 1990s. He was in a quandary and wanted to talk it through. The company had been generous in granting stock-based compensation (SBC), and the executive team had promised the financial community that it would offset that equity issuance by buying back stock in order to maintain a roughly flat number of shares outstanding.

问题在于,这位首席执行官认为,在互联网热潮的推动下,自家公司的股票被高估了。他把自己逼入了死角,摆在面前的问题是:是继续以溢价回购股票来兑现承诺,还是限制回购规模,放任流通股数量增加。

The issue was that the CEO perceived that his company’s stock, levitated by the dot-com boom, was overvalued. He had painted himself into a corner, and the question was whether he should continue to buy back stock at a premium to maintain his pledge, or limit buybacks and allow the number of shares outstanding to rise.

在伯克希尔·哈撒韦公司 2023 年年报中,公司董事长兼首席执行官沃伦·巴菲特写道:“所有股票回购都应当与价格挂钩。以低于企业价值的价格回购是明智之举,但若溢价回购,则实属愚蠢。”¹ 资本配置的简单目标就是低买高卖。低买意味着付得比收得少,高卖则意味着收得比付得多。价格与价值的区分至关重要。价格是你付出的或收到的金额。而价值,对能产生现金流的资产而言,是未来现金流的现值。当公司以低于其价值的价格收购一项资产,或以高于其价值的价格出售一项资产时,它就创造了价值。上市公司发行和回购股票。发行股票的主要原因包括为收购融资、补偿员工、支撑运营,以及调整公司资本结构中债务与股权的比例。回购股票则是将资本返还给出售股票的股东。回购还可能带来其他被视为益处的效果,包括释放出股票被低估的信号、降低现金误配的风险、提高每股收益,以及抵消股权激励所带来的稀释效应。²

In the 2023 annual report of Berkshire Hathaway, Warren Buffett, the company’s chairman and CEO, wrote, “All stock repurchases should be price-dependent. What is sensible at a discount to business-value becomes stupid if done at a premium.”1 The simple goal of capital allocation is to buy low and sell high. Buying low means giving less than you receive, and selling high means receiving more than you give. The distinction between price and value is crucial. Price is what you pay or receive. Value, for assets that generate cash, is the present value of future cash flows. Companies create value when they acquire an asset at a price below its value or sell an asset at a price above its value. Public companies issue and retire equity. The main reasons to issue equity are to finance an acquisition, compensate employees, fund operations, and change the mix of debt and equity in the company’s capital structure. Retiring equity returns capital to the selling shareholders. Buybacks may achieve additional perceived benefits including signaling the shares are undervalued, reducing the risk of misallocating cash, increasing earnings per share, and offsetting the dilution from SBC.2

任何资本配置决策的正确性,答案都是“看情况而定”。正如沃伦·巴菲特在上文引述中所言,首要考量是价格与价值之间的差距。在一个价位上明智的选择,在另一个价位上可能并不明智。

The proper answer about the virtue of any capital allocation decision is, “it depends.” As Warren Buffett suggests in the quotation above, the primary consideration is the gap between price and value. What is wise at one price may be unwise at another.

分析师们时不时会发研究报告,列出那些在回购股票方面做得最好的公司。他们用回购后的股东总回报来计算。他们这么算,是假定这些公司是故意回购被低估的股票。

From time to time, analysts publish research listing the companies that were the best at buying back stock. They calculate this using total shareholder returns after the buyback. The presumption is that the companies intentionally repurchased shares that were undervalued.

但这类研究往往忽略了,这些公司中有一部分还同时发行了股票,通常以股权激励(SBC)的形式。如果管理层认为价格偏离价值,并且既发行又回购股票,那么其中一项操作就违背了资本配置的目标(见表 1)。到底是哪一项?

But that research often fails to note that a subset of those companies also issued equity, commonly in the form of SBC. If executives have a view that price differs from value, and they both issue and retire stock, one of those actions fails the goal of capital allocation (see exhibit 1).3 Which one is it?

大多数高管嘴上说想为股东创造价值,却一边增发股票一边回购,心里毫无矛盾。

Most executives say they want to create shareholder value, yet suffer little or no cognitive dissonance as they issue and buy back stock at the same time.

多数基本面投资者在做投资决策时,都会把管理层的资本配置能力纳入考量。

Most fundamental investors consider the capital allocation skills of management in their investment process.

他们也会直接评估未来现金流的现值,或是间接借助估值倍数来给企业定价。但鲜有投资者会明确考虑到,当公司发行或回购被错误定价的股票时,可能引发的财富转移效应。

They also value the business either directly by assessing the present value of future cash flows or indirectly using a valuation multiple. But few investors explicitly consider the wealth transfers that a company can cause when it issues or retires stock that is mispriced.

这份报告讨论的是那些在同一时间或短期内既发行又回购股票的公司。我们会探讨公司对外宣称的发行与回购股票的理由,然后按股票薪酬发行量高于或低于中位数,以及回购量高于或低于中位数,把美国上市公司分成四类。这种划分形成一个 2×2 的矩阵,让我们能审视每个象限中股东的总回报。

This report is about companies that both issue and retire shares simultaneously or within a short period of time. We will examine the reasons companies say they issue and buy back stock. We then segregate U.S. public companies into those that are above and below the median in issuance via SBC, as well as those that are above and below the median in share buybacks. This sorting creates a two by two grid that allows us to examine the total shareholder returns in each of the quadrants.

这份报告的读者,是那些认真思考资本配置的董事会成员和高管,以及那些在评估公司时,想要衡量这些技能的投资者。

The audience for this report is boards of directors and executives who think carefully about capital allocation, as well as investors who want to assess those skills among the companies they evaluate.

Wealth Transfers

Wealth Transfers

大量学术研究显示,企业在选择发行和回购股票的时机上颇为擅长。平均而言,它们低买(价格低于价值)高卖(价格高于价值)。4 这一行为引发了财富转移。

Lots of academic research shows that companies are good at timing the issuance and retirement of equity. On average, they buy low (price below value) and sell high (price above value).4 This creates wealth transfers.

当一家公司回购被低估的股票时,财富从卖方转移到了持续持有的股东手中。

When a company buys back undervalued stock, wealth is transferred from the sellers to the ongoing holders.

当一家公司发行被高估的股票时,财富便从买家手中转移到了长期持有者手中。

When a company sells overvalued stock, wealth is transferred from the buyers to the ongoing holders.

实证来看,通过回购转移的财富少于通过发行股票转移的财富。5 机构投资者在与公司交易时,通常比个人投资者更为精明。6

Empirically, less wealth is transferred through buybacks than through equity issuance.5 Institutional investors are generally more astute than individual investors when transacting with a company.6

公司回购被低估的股票或增发被高估的股票时,对持续持股的股东而言,行动或不行动的后果截然不同。若公司回购被低估的股票,按兵不动的股东持股比例上升,同时每股价值随之提高。若公司增发被高估的股票,持续持股的股东每股价值同样提升,但此时,这些股东显然应与管理层一同卖出,方能更占优势。

The implications for action or inaction are different for ongoing shareholders in cases when a company is buying undervalued stock or selling overvalued stock. If a company buys undervalued stock, a shareholder doing nothing increases his or her stake while value per share rises. If a company sells overvalued stock, the value per share also increases for ongoing holders but, of course, that shareholder is better off selling alongside management.

股票的时间加权平均回报率,因这类财富转移,可能与其美元加权回报率有所差异。时间加权回报率考量的是某段时期内股价变动及股息情况。

A stock’s time-weighted average return can be different than its dollar-weighted return as a consequence of these wealth transfers.7 Time-weighted returns consider stock price change and dividends over some period.

按美元加权计算的回报率,既包含了股价变动和股息,也计入了与股票发行或回购相关的资金流入与流出。

Dollar-weighted returns incorporate stock price change and dividends but also include the inflows and outflows associated with issuance or retirement of equity.

股东总回报是一种时间加权回报。但由于股票发行和回购会改变公司的股本规模,如果公司在价格错估时买卖股票,以美元加权计算的回报可能与时间加权回报相差甚远。

Total shareholder return is a time-weighted return. But since issuance and retirement change a company’s equity capitalization, dollar-weighted returns can be a lot different than time-weighted returns if the company buys or sells mispriced stock.

设想一家公司有 1000 股流通股,每股交易价 100 美元,市值 10 万美元。随后股价翻倍,公司增发 1000 股,市值升至 40 万美元(2000 股 × 200 美元)。之后股价回落至 100 美元,市值变为 20 万美元。

Consider a firm that has 1,000 shares outstanding that trade at $100 per share for a market capitalization of $100,000. The stock then doubles and the company issues an additional 1,000 shares, raising the market cap to $400,000 (2,000 x $200). The shares then go back to $100 for a market cap of $200,000.

没有交易的原始股东盈亏持平。而那些在 200 美元买入的人,损失了一半本金。假设没有股息,时间加权收益率为零,因为股价终点回到起点。但用内部收益率(IRR)计算的美元加权收益率,则为 -26.8%。

The original shareholders who did not transact are flat. But those who bought shares at $200 have lost one-half of their money. The time-weighted return is zero, assuming no dividend, because the stock ended where it began. But the dollar-weighted return, calculated using the internal rate of return (IRR), is -26.8 percent.

现在设想一家公司,发行在外的股票有 1000 股,每股市价 100 美元,但股价跌至 50 美元。这一次,公司回购了 500 股。假设股价回升至之前的 100 美元,持续持有者不赚不亏,而公司若重新发行这些股票,将赚得翻倍的钱。时间加权回报率为零,但美元加权回报率为 13.3%。

Now think of a company that has 1,000 shares outstanding that trade at $100, but the stock drops to $50. This time, the company buys 500 shares. Assuming the stock reverts to its prior price of $100, the ongoing holders are flat and the company, should it reissue the shares, would double its money. The time-weighted return is zero but the dollar-weighted return is 13.3 percent.

理想情况下,投资者希望找到能引发财富转移、让长期持股者受益的公司。这些公司能够有条不紊地识别价格与价值之间的差距,并可靠地据此行动。

Ideally, investors want to find companies that trigger wealth transfers that benefit long-term ongoing holders. These are the companies that can methodically discern gaps between price and value and reliably act on them.

公司发行股票的原因

Reasons Companies Issue Equity

附录 2 展示了 2000 年至 2023 年间,在美国主要交易所上市的所有公司的股票发行收益。这一时期,股票发行总额达 9.7 万亿美元,其中股权融资的并购(M&A)交易占总量的 58%,紧随其后的是股票薪酬(SBC),占比 22%,以及增发股票(SEOs),占比 20%。增发股票是指向投资者发行的新股,不包括首次公开募股(IPOs)。

Exhibit 2 shows the proceeds from equity issuance for all companies with stocks listed on the major exchanges in the U.S. from 2000 to 2023. Over this period, equity issuance was $9.7 trillion, with equity-financed merger and acquisition (M&A) deals making up 58 percent of the total, followed by stock-based compensation (SBC) at 22 percent, and seasoned equity offerings (SEOs) at 20 percent. SEOs are new shares that are issued to investors that are not initial public offerings (IPOs).

请注意,财务会计准则委员会直到 2006 年才要求企业在损益表中披露股票薪酬(SBC),这意味着这一股权发行总额被略有低估。

Note that the Financial Accounting Standards Board did not require companies to disclose SBC on the income statement until 2006, which means this total of equity issuance is modestly understated.

高管们在决定发行股票时,考量的主要因素包括对股价与内在价值之间差距的感知、每股收益可能被稀释的程度、为股权激励预留的份额,以及达成或维持目标资本结构。

The main factors that executives consider when they decide to issue equity include the perceived difference between the price and value of the stock, potential dilution in earnings per share, the provision for SBC, and reaching or maintaining a target capital structure.8

并购。截至 2023 年的 25 年间,企业以现金支付多数并购交易。但以股权融资的交易为数众多,成为整体股票发行的首要原因。其中最著名的案例当属美国在线(AOL)与时代华纳公司(Time Warner Inc.)的合并。该交易于 2000 年 1 月宣布,正值互联网泡沫巅峰。高管们将此交易描述为对等合并,但按过往年度销售额计算,时代华纳的规模是美国在线的四倍。美国在线以超过 1500 亿美元股权收购时代华纳,合并后实体中美国在线股东最终持股 55%。9 此次联姻被称为“史上最糟糕的合并”。10

M&A. In the 25 years ended in 2023, companies funded a majority of M&A deals with cash. But enough deals are financed with equity that it is the leading reason for overall issuance. Among the best known of these was the merger between America Online (AOL) and Time Warner Inc. That deal was announced in January 2000, near the peak of the dot-com boom. The executives presented the transaction as a merger of equals but Time Warner was four times larger than AOL based on trailing annual sales. AOL offered more than $150 billion in equity to buy Time Warner, and AOL shareholders ended up with 55 percent of the combined entity.9 The tie-up has been described as “the worst merger of all time.”10

以股权融资的并购交易能让买方保住现金、避免举债,或者做成超出自身债务承受能力的更大交易。此外,卖方可能坚持要股权,以便递延纳税义务。这适用于……

M&A deals financed with equity allow buyers to preserve cash, avoid debt, or do deals larger than their debt capacity would allow. Further, sellers may insist on receiving equity so as to defer their tax liabilities. This applies

在符合免税重组条件的并购中,这一点尤为明显。例如,从 2023 年 10 月到 2024 年 5 月,美国三家大型石油公司宣布了以股权融资的收购,合计价值近 1300 亿美元。卖方对免税交易的偏好,是决定支付方式的重要因素。

to mergers that qualify as tax-free reorganizations. For example, from October 2023 to May 2024, three major oil companies in the U.S. announced acquisitions financed with equity that had a combined value of almost $130 billion. The preference of the sellers for tax-free deals was an important factor in the payment method.

值得注意的是,这些公司在 2022 年和 2023 年间合计回购了近 750 亿美元的股票。

Remarkably, these same companies bought back a combined total of nearly $75 billion of stock in 2022 and 2023.

学术研究表明,以股票进行交易的公司股东,其处境远不如以现金进行交易的公司股东。11 其逻辑在于,公司在认为自身股价被高估时,才会发行股票。这并不意味着股票交易本身不好,但高管和投资者必须核实此类交易是否具有经济合理性。

Academic studies show that the shareholders of companies that do deals with stock fare substantially worse than those of companies that do deals with cash.11 The thinking is that companies issue equity when they consider it to be overvalued. This does not mean that stock deals are inherently bad, but executives and investors must verify that such deals make economic sense.

沃伦·巴菲特曾表示,他对发行股票十分谨慎。但 1998 年 6 月,他拿出伯克希尔·哈撒韦约 20% 的股份,收购了通用再保险公司,这是一家跨国财产与意外伤害再保险公司。值得注意的是,从 1997 年 1 月初到交易宣布之时,伯克希尔·哈撒韦的 B 类股上涨了 143%,而同期标普 500 指数上涨了 52%。标普 500 指数是一个由约 500 只市值最大的美国股票构成的指数。

Warren Buffett has said he is chary of issuing equity. But in June 1998, he pledged about 20 percent of Berkshire Hathaway’s shares to acquire General Re, a multinational property and casualty reinsurance company.12 Notably, from the beginning of January 1997 to the announcement of the deal, Berkshire Hathaway’s Class B stock was up 143 percent versus a gain for the S&P 500 of 52 percent. The S&P 500 is an index of approximately 500 U.S. stocks with the largest market capitalizations.

通用再保险在运营上有不少问题,伯克希尔花了几年时间才理顺。但即便解决了通用再保险的麻烦,巴菲特仍称当初为收购这家公司发行那么多股票是“一个可怕的错误”。他补充道:“我的错误让伯克希尔的股东付出远多于所得。”13

General Re had a number of operational issues that took Berkshire some years to fix. But even after addressing General Re’s problems, Buffett called it “a terrible mistake” to issue so many shares to buy the business. He added, “My error caused Berkshire shareholders to give far more than they received.”13

价格与价值之间的差异,是决定股票融资收购中支付对价的重要考量。假设某公司确定其能为目标公司支付的最高价格为每股 50 美元,而其自身股票的价值为每股 100 美元。如果买方自身的价值与价格一致,那么它可以提出 0.5 股换 1 股的方案,这笔交易在价值上就是中性的。

The difference between price and value is an important consideration in determining what to pay in a deal financed with stock. Say a company determines that the maximum it can pay for a target is $50 per share and that the value of its own stock is $100 per share. If the buyer’s value and price are the same, it can offer 0.50 shares and the deal is neutral to value.

如果收购方的股价是 150 美元,它可以拿出 0.33 股作为对价,并为股东增加价值,因为用高估的股票支付意味着稀释更少。同理,如果收购方的股价是 50 美元,它就必须拿出 1 股,这会损害收购方现有股东的价值。

If the buyer’s stock price is $150, it can offer 0.33 shares and add value for its shareholders because paying with overvalued stock means lower dilution. Similarly, if the buyer’s stock price is $50, it has to offer 1.0 shares, which destroys value for the buyer’s ongoing stockholders.

调查显示,通常有 50% 到 80% 的财务高管认为自家公司的股价低于其公允价值。14 当公司股价被低估时,它可以通过股权融资来完成一笔交易。

When surveyed, 50 to 80 percent of financial executives typically say they believe the stock price of their company is below its fair value.14 A company can do a deal using equity financing when its stock is undervalued.

但只有当目标公司的价格与价值之比,等于或低于买方自身的价格与价值之比时,这笔收购对股东价值才是中性的或增值的。

But the ratio of the target’s price to value has to be equal to or lower than the ratio of the buyer’s price to value for it to be neutral or additive to shareholder value.

目标公司的价值是买方愿意支付的最高价格,其中通常包含为反映预期协同效应而支付的控制权溢价。在活跃的公司控制权市场中,价格低于价值的情况不太可能出现。

The target’s value is the maximum price the buyer should be willing to pay, and it generally includes a premium for control that reflects anticipated synergies. Such discounts in price to value are unlikely in an active market for corporate control.

股权激励。过去四分之一个世纪里,股权激励是第二大的股权发行来源。图表 3 展示了罗素 3000 指数成分公司的股权激励占销售额的比重,该指数衡量约 3000 只美国股票的表现,几乎涵盖了全部可投资股票市场。这一比重从 2006 年的 0.2% 升至 2023 年的 1.3%。股权激励的年复合增长率为 15.3%,销售额的年复合增长率为 3.8%。股权激励的金额从 2006 年的 260 亿美元增至 2023 年的 2900 亿美元。

Stock-Based Compensation. Stock-based compensation has been the second largest source of equity issuance in the last quarter century. Exhibit 3 shows SBC as a percent of sales for companies in the Russell 3000, an index that measures the performance of roughly 3,000 U.S. stocks and represents nearly all of the investable equity market. That percentage went from 0.2 of sales in 2006 to 1.3 of sales in 2023. The compound annual growth rate was 15.3 percent for SBC and 3.8 percent for sales. The dollar sum of SBC rose from $26 billion in 2006 to $290 billion in 2023.

近几十年来,以股权激励(SBC)占销售额比例衡量的指标之所以上升,原因众多。其中包括:公司整体构成向更多授予此类激励的企业(如科技公司)倾斜;机构强制力,即公司间相互模仿的倾向;在股权激励更为普遍的劳动力市场竞争中,SBC 填补了员工现金薪酬减少的部分;这反映了 CEO 薪酬上升,其中 SBC 成为增幅的重要组成部分;以及激励和留住员工带来的感知益处。

There are a number of reasons that SBC as a percent of sales has increased in recent decades. These include a shift in the overall mix of companies toward those that grant more SBC (e.g., technology firms); the institutional imperative, which says that companies imitate one another;15 competition in a labor market where SBC is more common; SBC filling in for lower cash payments to employees;16 a reflection of rising CEO pay with SBC making up a large component of the increase;17 and the perceived benefit of incentivizing and retaining employees.18

附录 4 显示,以销售额衡量,股票薪酬成本(SBC)占销售额的比例与公司规模密切相关。在罗素 3000 指数中,规模最小的十分之一公司,其股票薪酬成本占销售额比例的中位数为 3.5%,而规模最大的十分之一公司则为 0.5%。随着公司规模扩大,股票薪酬发放占销售额的比例往往呈下降趋势。

Exhibit 4 reveals that SBC as a percent of sales is closely related to the size of the company, as measured by sales. The median SBC as a percent of sales is 3.5 percent for the smallest decile in the Russell 3000 and 0.5 percent for the largest. SBC issuance as a percent of sales tends to decline as companies grow larger.

公司发行新股时会造成股权稀释。稀释会降低现有股东的持股比例,其计算方式为 1 减去发行前流通股数除以发行后流通股数。例如,一家拥有 1000 股流通股的公司发行 100 股新股,其股东将面临约 9.1% 的稀释,因为他们现在只持有公司股份的 90.9%(1–[1000/1100] = 1–0.909 = 0.091)。

A company causes dilution when it issues new shares. Dilution lowers the percentage ownership of existing shareholders and is calculated as one minus the shares outstanding before issuance divided by the shares outstanding after issuance. For example, the holders of a firm with 1,000 shares outstanding realize about 9.1 percent dilution when the company issues 100 new shares, as they now own 90.9 percent of the company (1 – [1,000/1,100] = 1 - 0.909 = 0.091).

规模最小的两个十分位区间公司,三年期内稀释的市值中位数相对较高,达到 8.5%(见附件 5)。规模最大的两个十分位区间公司的稀释中位数则为负值,这意味着不出售股票的股东,其持股比例会增加 1% 到 4%。再次印证了一个典型事实:随着公司规模扩大,稀释程度会下降,最终转为负值。

The companies in the smallest two deciles have median three-year dilution that is relatively high at 8.5 percent (exhibit 5). The median dilution for firms in the largest two deciles is negative, which means that shareholders who do not sell increase their percentage ownership between one and four percent. Again, the stylized fact is that dilution falls, and is eventually negative, as companies grow larger.

把员工股票薪酬(SBC)对公司价值的影响建模,并非易事。理论上有两种基本方法能殊途同归。第一种方法,如会计准则所规定,把员工股票薪酬作为损益表上的费用处理,且不因公司尚未发行的股票而调整未来流通股数。第二种方法,则如现金流量表所示,将员工股票薪酬加回现金流,并调整未来流通股数,以反映员工股票薪酬带来的稀释效应。

Modeling the impact of SBC on corporate value is tricky. There are two basic approaches that get to the same answer in theory.19 The first treats SBC as an expense on the income statement, as accounting rules stipulate, and does not adjust future shares outstanding for stock the company has not issued. The second adds back SBC to cash flow, as is done in the statement of cash flows, and adjusts future shares outstanding to reflect the dilution from SBC.

投资者和公司最常用的自由现金流定义,即经营现金流减去资本支出,与金融学理论定义并不吻合,而且还需预估摊薄影响。表 5 中的数据为此类建模提供了有用的参考类别。

The most common definition of free cash flow that investors and companies use, cash flow from operations minus capital expenditures, does not match the theoretical definition in finance and requires anticipating dilution.20 The data in exhibit 5 provide useful reference classes for that modeling.

以股票为基础的薪酬,尤其是针对高管的,意在实现三个往往难以平衡的目标。21 第一个目标是为员工创造价值提供恰当的激励。研究表明,股票薪酬能激励高管,但对普通员工效果有限。22 激励的强度可能因员工的年龄和任职年限而有所不同。23

Stock-based compensation, especially for executives, seeks to satisfy three goals that can be difficult to balance.21 The first is to create proper incentives for employees to create value. Research suggests that SBC can incentivize executives yet has a limited effect on the rank and file.22 The strength of the incentives can vary based on employee age and tenure.23

第二个目标是留住员工。请注意,薪酬只是决定员工留存率的因素之一,其他因素还包括工作场所的认可、成长机会、工作与生活的平衡,以及

The second objective is to retain employees. Note that compensation is only one of the factors that determines retention. Others include workplace recognition, the opportunity for growth, balance between work and life, and

工作保障。24 Counterpoint Global 可持续发展研究团队的分析显示,员工留存率与股东总回报之间存在正相关关系。25 有证据支持这样一种观点,即面向广大员工群体的股票薪酬有助于提升留存率,但授予的股票一旦归属,其留存效果便会减弱。26

job security.24 Analysis by the Sustainability Research team at Counterpoint Global shows a positive correlation between retention and total shareholder returns.25 There is support for the proposition that SBC for a broad base of employees helps retention, but the increase in retention diminishes after grants vest.26

最终目标是确定一个总体薪酬水平,既要能吸引、留住并奖励最优秀的员工,又要为非员工股东创造价值。给员工支付优厚薪酬,与最大化股东价值并不矛盾。

The final goal is to find the level of overall compensation that attracts, retains, and rewards the best employees while creating value for the non-employee shareholders. Paying employees well can be consistent with maximizing shareholder value.

员工与股东的利益在基于股票的薪酬(SBC)设置得当的激励机制下是一致的。这也是私募股权收购交易中薪酬方案的一大优点。27 高管薪酬水平通常与股东回报挂钩,而获益颇丰的股东很少会对高管薪酬有微词。28

Employees and shareholders are aligned when SBC creates a proper incentive. This is one of the virtues of pay packages in private equity buyout deals.27 The level of executive compensation is generally tied to shareholder returns, and shareholders who have fared well rarely have qualms about executive pay.28

股东与员工之间的财富转移,在股价与其价值相悖时便可能发生。比如,以被低估的股票支付 SBC,财富便从现有股东流向员工;反之,以被高估的股票支付,财富则从员工流向现有股东。

But wealth transfers between shareholders and employees can occur if the price of the stock differs from its value. For instance, issuing undervalued stock for SBC transfers wealth from ongoing shareholders to employees. Issuing overvalued stock transfers wealth from employees to ongoing shareholders.

错位风险出现在公司把股权激励薪酬(SBC)当作支付工具、而非激励性薪酬计划来使用时。这种情况发生在公司股价表现不佳后,增发新股以恢复此前或承诺的薪酬水平。例如,2022 年罗素 3000 指数下跌 19%,而股权激励薪酬总额却上升 19%。

The risk of misalignment arises when companies use SBC as a pay delivery system versus an incentive compensation program. This happens when a company issues additional shares to replenish pay to former or pledged levels following poor stock performance.29 For instance, in 2022 the Russell 3000 Index was down 19 percent and total SBC was up 19 percent.

附件 6 显示,以股权激励支出(SBC)占销售额比例衡量,位列前 20% 的公司,其股票超额回报率明显低于位列后 20% 的公司。这些数据覆盖 2007 年 7 月至 2018 年 12 月。这并不意味着股权激励水平决定了超额回报,但结果与一个观点相符:股权发行往往预示着未来回报欠佳。

Exhibit 6 shows that the stocks of the companies in the top 20 percent of SBC as a percent of sales produced substantially lower excess stock price returns than those companies in the bottom 20 percent. These data cover a period from July 2007 to December 2018. This does not mean that the SBC levels caused the excess returns, but the result is consistent with the point that equity issuance often portends subpar future returns.

按股票薪酬占销售额比例划分的五分位组(1=最低,5=最高)

Quintile Based on Stock-Based Compensation to Sales (1=Least, 5=Most)

把股权激励做对并非易事,原因有好几个。由自主感、掌控感和使命感所激发的员工内在动力,在预测工作表现上比薪酬更有效。30 股权激励的效果也受到局限,因为持股多元化的股东通常属于风险中性,而员工往往厌恶风险。结果,股票对股东的价值高于对员工的价值。对员工而言,股权与自身人力资本挂钩,反而降低了多元化程度,流动性差,估值也困难。

Getting SBC right is a challenge for a number of reasons. Intrinsic employee motivation, promoted by a sense of autonomy, mastery, and purpose, does a better job of predicting worker performance than pay does.30 The effectiveness of SBC is also limited because shareholders with diversified portfolios are generally risk neutral whereas employees are commonly risk averse. As a result, equity is more valuable to shareholders than workers. For employees, equity is correlated with human capital and therefore reduces diversification, is not liquid, and can be difficult to value.

当员工可以自行选择薪酬形式时,他们往往更偏爱现金而非股票。例如,订阅视频服务公司 Netflix 在 2006 年敲定了一项薪酬安排,允许符合条件的员工为次年申请现金与股票的组合。大约 60% 到 75% 的员工选择全部要现金。31 2022 年底,跨国电商公司 Shopify 推出了类似的项目,名为“灵活薪酬”(Flex Comp)。据报道,软件工程师中流行的一种选择是“全部或大部分薪酬以现金形式领取”,这一数据点也有事实支撑:Shopify 在 2023 年授予的限制性股票单位总价值不到 2022 年的三分之一。32

Employees who are given a choice of the form of pay often prefer cash to stock. For example, Netflix, a subscription video service, put into place a compensation arrangement, finalized in 2006, whereby eligible employees could request a mix of cash and stock for the following year. About 60 to 75 percent of employees requested all cash.31 In late 2022, Shopify, a multinational e-commerce company, launched a similar program called “Flex Comp.” It was reported that a popular choice among software engineers was to get “all or most of their compensation in cash,” a data point supported by the fact that the total value of restricted stock units that Shopify granted in 2023 was less than one-third of what it was in 2022.32

增发股票(SEOs)是第三种股权发行形式。与该研究所发现的公司往往擅长低买高卖相吻合,数据显示,进行增发的公司在交易完成后的平均股票回报率低于平均水平。33 然而,引入其他考量因素后,这一宽泛的结论需要进一步细化。

Seasoned Equity Offerings. SEOs are a third form of equity issuance. Consistent with the finding that companies tend to be good at buying low and selling high, the research shows companies that do SEOs have subpar stock returns, on average, following the deal.33 But introducing other considerations refines this broad conclusion.

举例来说,公司进行增发的动机值得关注。公司通常会列举三种理由来为交易辩护:调整资产负债表结构(提高股本与债务之比)、为投资筹集资金,以及“一般公司用途”——这是涵盖任何行动的笼统说法。研究显示,那些为了调整资产负债表结构或一般公司用途而发行股票的公司,其股票表现逊于市场。而那些因特定投资而进行增发的公司,则不会表现不佳。

For example, a company’s motivation to do an SEO is relevant. There are three reasons firms cite to justify a deal: to recapitalize the balance sheet (increasing the ratio of equity to debt); to fund an investment; and for “general corporate purpose,” a catchall for any action. The research shows that the stocks of the companies that issue stock earmarked for recapitalizing the balance sheet or for general corporate purposes underperform the market. Companies that do an SEO for a specific investment do not underperform.34

SEO 的购买方同样具有相关性。机构投资者往往比个人投资者更为精明。35 机构投资者大量配置的 SEO,其表现优于那些没有此类配置的 SEO。36 这一规律在 IPO 及交易中同样明显。37

Who buys the SEO is also relevant. Institutional investors tend to be more savvy than individual investors.35 SEOs with large institutional allocations outperform those without those allocations.36 This pattern is also evident in IPOs and trading.37

公司回购股权的原因

Reasons Companies Retire Equity

美国上市公司在 2000 年至 2023 年间共计注销了 14 万亿美元的股权(见图表 7)。股权净注销之所以出现,是因为小公司往往发行股票,而大公司通常回购股票。38 本世纪以来,美国上市公司主要依靠经营现金流来支撑增长,债务增加也贡献了一小部分。过去 25 年间,回购规模可观,但一直争议不断。39

U.S. public companies retired $14.0 trillion of equity from 2000 to 2023 (see exhibit 7). There is net retirement of equity because small companies tend to issue equity and large companies generally retire equity.38 In this century, U.S. public companies have funded their growth largely with cash from operations. There was also a small contribution from an increase in debt. Buybacks have been substantial in the last 25 years but remain controversial.39

理想情况下,公司应当留意沃伦·巴菲特的建议,只在股价低于其内在价值时进行回购。有些公司擅长此道,证据表明,回购总体上为持续股东带来了适度好处。40 回购的规模与方式,也能反映公司潜在低估信号的强弱。41

Ideally, companies would pay attention to Warren Buffett and buy back shares only when their price is below their value. Some companies are good at this, and the evidence suggests that buybacks modestly benefit ongoing shareholders in the aggregate.40 The size and method of buybacks can also provide insight into the strength of the potential signal of undervaluation.41

但实际上,许多公司决定回购股票,是因为手头现金充裕,想抵消员工股票补偿(SBC)带来的股权稀释,并试图提振每股收益(EPS)。42 然而,这种提升每股收益的动机,与金融理论和实证研究背道而驰。43

But in reality many companies decide to buy back stock because they have excess cash, want to offset dilution from SBC, and seek to boost earnings per share (EPS).42 The motivation to increase EPS flies in the face of finance theory and empirical research.43

绝大多数的首席财务官(CFO)在调查中表示,在公司股价被低估时进行回购相当重要或极为重要。44 但 CFO 们通常认为自家公司股票被低估,他们不善于预测结果,而且常常根据“当前价格相对于历史高低点的位置”来评估自家股票的价值。45

The vast majority of chief financial officers (CFOs), when surveyed, say that buying back shares when they are undervalued is important or very important.44 But CFOs generally think the stocks of their companies are undervalued, are poor at predicting outcomes, and commonly value their own stock based on the “current price relative to historic highs and lows.”45

委托—代理问题为理解回购提供了一个有用的分析框架。这一问题描述了委托人与代理人之间目标冲突的情形。在此语境下,股东是委托人,高管是代理人。代理成本则是指那些损害委托人利益却惠及代理人的行为。

The principal-agent problem provides a useful way to think about buybacks. This problem describes the conflict between the objectives of principals and agents. In this case, shareholders are the principals and executives are the agents. Agency costs are actions that harm principals and benefit agents.

回购既能缓和代理成本,也能制造代理成本。当公司将富余现金返还给投资者,从而避免把资金挥霍在低回报投资或高管特权上时,代理成本得以降低。但当回购被用来为高管谋利,或为摆出表面成绩而未创造实际价值时,代理成本便随之滋生。

Buybacks can mitigate or create agency costs.46 They reduce them when a company returns excess cash to investors and, as a result, does not squander the capital on investments with low returns or perquisites for executives.47 But they create agency costs when they are deployed to benefit executives or to show superficial results without creating value.48

例如,最新研究指出,较高的股权激励支出(SBC)与更频繁的股票回购活动之间存在因果关系,旨在抵消股权稀释。许多回购股票的公司频繁操作,这限制了它们择时市场的能力。49 此外,回购与高管出售持股之间似乎存在正相关关系。50

For instance, recent research points to a causal link between higher SBC and greater buyback activity with the intent to offset dilution. Many companies that buy back stock do so frequently, which limits their ability to time the market.49 And there appears to be a positive correlation between buybacks and sales of equity holdings by executives.50

发行与回购之间的时间差,对于寻求管理流通股稀释的公司而言可能相当关键。大多数股票薪酬(SBC)随时间逐步归属,通常为四年。若在授予日发行的股票在归属期内价格上涨,那么为抵消稀释而回购股份所支付的价格,将高于最初发行这些股份的成本。

The lag between issuance and retirement can be relevant for companies seeking to manage dilution in shares outstanding. Most SBC vests over time, commonly four years. If stock issued at the grant date rises over the vesting period, the price paid to retire shares in order to offset dilution will exceed the original cost to issue the shares.51

理论与实践

Theory and Practice

股票的发行或回购,其指导原则是公司所得大于所予。

The guiding principle in the issuance or retirement of equity is for the company to receive more than it gives.

这意味着公司在股价过高时发行股票,从而增加供给;在股价过低时回购股票,从而增加需求。总体来看,企业在这一点上做得相当不错。

This means issuing shares that are overvalued and retiring shares that are undervalued. Overall, companies are reasonably good at this. One way to think about it is that firms increase supply by issuing shares when prices are too high and increase demand by retiring shares when prices are too low.52

大量证据表明,并购交易或增发(SEO)中发行股票,往往预示着发行人后续股东回报不佳。但这并非一概而论。在特定条件下,以股权融资的收购或增发可以具备合理的经济意义。换言之,存在这样的情况:公司即便以公平价值甚至低估的价格发行股票,只要换来的现金流足以弥补这一平价或折价,便仍属明智之举。

There is a great deal of evidence that issuing stock in an M&A deal or an SEO is often a predictor of poor subsequent shareholder returns for the issuer. But this is not a blanket observation. Under certain conditions an equity-financed acquisition or an SEO can make sound economic sense. In other words, there are cases when a company can issue shares that are at fair value, or even undervalued, if they fetch a stream of cash flows that compensates for that parity or discount.

我们现在更仔细地审视股票薪酬(SBC)和回购,部分原因在于回购的动机与股票薪酬所伴随的股份发行密切相关。

We now focus more closely on SBC and buybacks, in part because the motivation for buybacks is related to the share issuance associated with SBC.

理论上,SBC 应当激励员工有效工作,成为留住人才的机制,并平衡员工与股东的利益。

In theory, SBC should provide an incentive for employees to work effectively, be a mechanism to retain workers, and balance the interests of employees and shareholders.

实际上,不同公司在此目标上的执行成效参差不齐。此外,对许多公司而言,SBC 已演变成向员工支付固定金额的工具,使他们的收益与股东利益脱节,并且这种做法似乎深受机构强制力的影响,即追随同行与竞争对手的步伐。

In practice, SBC meets those objectives with varying degrees of success from one company to the next. Further, for many companies SBC has evolved into a mechanism to pay employees a certain amount, disconnecting their outcomes from those of shareholders, and it appears heavily influenced by the institutional imperative to follow the actions of peers and competitors.

理论上,回购应当为持续持股的股东增加价值,并让他们有能力安排自己的税务负担时机。

In theory, buybacks should add value to ongoing shareholders and provide them with an ability to time their tax liabilities.

在实践中,公司常常将股票回购的力度与股权激励(SBC)导致的稀释程度挂钩,并将其视为管理每股收益的一种手段。

In practice, companies regularly tie the magnitude of their buyback programs to the dilution that SBC causes and look to buybacks as a means to manage EPS.

因为实践可能与理论相悖,有些公司在同一时期既发行又回购大量股票。但研究支持这样的观点:公司才是聪明钱,尤其是在发行股票时。这促使我们将注意力集中在那些既大量发行又大量回购股票的公司群体上,看看它们的股东回报与市场其他公司相比表现如何。

Because practice can be at odds with theory, some companies issue and retire a meaningful amount of stock at the same time.53 Yet research supports the idea that companies are the smart money, especially when they issue stock.54 This leads us to narrow our attention to the subset of companies that both issue and retire significant amounts of stock and ask how their shareholder returns stack up versus the rest of the market.

SBC、回购与股东总回报

SBC, Buybacks, and Total Shareholder Returns

为进行这项分析,我们从罗素 3000 指数成分股出发,筛选出销售额至少为 10 亿美元的公司股票。对于 2021 年至 2023 年的每一年,我们分别计算股权发放比例,即股票薪酬(SBC)除以销售额,以及股权回购比例,即总回购金额除以市值。我们仅纳入至少有一年这些统计数据的公司。样本涵盖约 1350 只股票。

For this analysis, we start with the Russell 3000 universe and consider the stocks of companies with a minimum of $1 billion of sales. For each year from 2021 to 2023, we calculate issuance as SBC divided by sales and retirement as gross buybacks divided by market capitalization. We include only companies that have these statistics for at least one year. Our sample includes roughly 1,350 stocks.

我们分别取每家公司这三年的发行与回购指标平均值,再计算整个样本池中各指标的中间值。股权激励支出占营收比例的中间值为 0.8%,回购占市值比例的中间值为 1.5%。随后,我们根据公司在这两项指标上是否低于中间值(低)或高于中间值(高),将样本分成四个象限。基于这些分组,我们计算截至 2023 年 12 月 31 日的三个年度里,每个象限的平均及中间年度股东总回报(TSR)。

We take the average of these issuance and retirement measures over the three years for each company, and calculate the median of each metric for the universe. The median of SBC to sales is 0.8 percent and the median for buybacks to market cap is 1.5 percent. We then divide the population into quadrants based on whether the company is below the median (low) or above the median (high) in each measure. We use the combinations to calculate the average and median annual TSRs for each quadrant for the 3 years through December 31, 2023.

结果见附表 8。在股票薪酬(SBC)发行量低于中位数、回购量高于中位数的公司(右上角),其股东总回报(TSR)在该期间内最高。那些发行量与回购量均低于中位数的公司(左上角),股东总回报位居第二。

The results are in exhibit 8. The stocks of companies that were below the median on SBC issuance and above the median on buybacks (upper right corner) delivered the highest TSRs over the period. Those below the median in issuance and retirement (upper left corner) had the second-highest TSRs.

发行和回购量高于中位数的公司股票(右下角)是重点关注的主要群体,其股东总回报排名第三。最后,大量增发股票用于股权激励、却很少或从不回购自家股票的公司,股价表现最差。

The stocks of companies that were above the median in issuance and retirement (bottom right corner) are the primary group of interest. Their TSRs were the third highest. Finally, the stocks of companies that issued a lot of stock for compensation and bought few or no shares had the worst TSRs.

基于夏普比率(衡量风险调整后收益的指标)的排名,其顺序与平均和中等回报率的顺序一致。同期,罗素 3000 指数的复合年增长率为 8.5%。

The ranking based on the Sharpe ratio, a measure of risk-adjusted return, was in the same order as the average and median returns. The Russell 3000 Index rose at a compound annual rate of 8.5 percent over this period.

我们对截至 2023 年的 5 年期间进行了这项分析,发现“股权激励低/回购高”象限的股东总回报(TSR)仍然最高,而“股权激励高/回购低”象限的股东总回报最低。但其他象限的股东总回报排序发生了翻转,“股权激励高/回购高”的表现超过了“股权激励低/回购低”。

We ran this analysis for the 5 years ending in 2023 and found that the TSRs remained highest for the quadrant “SBC low/buybacks high” and lowest for “SBC high/buybacks low.” But the TSRs for the other quadrants flipped order, with “SBC high/buybacks high” outperforming “SBC low/buybacks low.”

需要明确的是,这些股东总回报(TSR)很可能受到许多与股票发行和回购无关的因素驱动,包括基本面及预期的变化、行业风险敞口、新冠疫情的影响以及利率水平。但高管和投资者应该了解实证研究关于股票发行揭示的规律,并以此为参照评估资本配置决策。

To be clear, these TSRs were likely driven by lots of factors that had nothing to do with equity issuance and retirement. These include changes in fundamentals and expectations, industry exposures, the impact of COVID, and interest rates. But executives and investors should understand what the empirical research shows about equity issuance and assess capital allocation decisions in that light.

Conclusion

Conclusion

长期以来,在资本配置上做得成功的公司,都是低买高卖。多数资本配置决策与公司运营相关,需要判断并购、资本支出、无形资产投资等投资能否带来令人满意的回报。但公司也可能通过以低于或高于价值的价格买卖股票,引发财富转移。

Companies that are successful at capital allocation over time buy low and sell high. Most capital allocation decisions relate to a firm’s operations and require determining the prospects for satisfactory returns on investments such as M&A, capital expenditures, and intangible investments. But companies can also trigger wealth transfers by buying and selling stock at prices below or above value.

以低于价值的价格回购股票的公司,是在进行一场财富转移,从卖出股票的股东手中转向继续持有的股东。反过来,高价发行股票则把财富从买家手中转向继续持有的股东。学术研究表明,公司确实擅长此道,尽管回购带来的转移规模小于增发。

A company that buys back shares below value initiates a wealth transfer from selling shareholders to ongoing shareholders. Conversely, selling overvalued shares transfers wealth from buyers to ongoing holders. Academic research shows that companies do this effectively, although the magnitude of the transfer is smaller for purchases than sales.

2000 年至 2023 年间,美国上市公司发行了近 10 万亿美元股票,同时回购注销了略超 14 万亿美元。多数发行是为了给并购提供资金,其次是股票薪酬(SBC)和增发。

From 2000 to 2023, public companies in the U.S. issued nearly $10 trillion in equity and retired just over $14 trillion. Most of the issuance was to fund M&A, followed by SBC and seasoned equity offerings.

发行股票总体上会导致现有股东后续回报不佳,但这一结果并非定论。例如,那些发行股票专门用于特定投资的公司,其回报往往优于为一般公司用途而发行股票的公司。

Issuing equity is associated with poor subsequent returns for ongoing shareholders in the aggregate, but this result is not definitive. For example, companies that issue equity earmarked to fund specific investments tend to have better returns than those that issue for general corporate purposes.

企业声称回购股票,主要动机在于传递股价被低估的信号。然而,也有证据表明,高管们对股票薪酬导致的稀释效应以及回购对每股收益的影响十分敏感。

The main reason companies say they buy back stock is to signal their stock is undervalued. But there is also evidence executives are very mindful of dilution due to SBC and the impact of buybacks on earnings per share.

总体而言,小公司的持续股东会经历股权稀释,即持股比例的下降,这意味着这些公司发行的股权多于其回购的。而大公司的持续股东平均而言持股比例会上升,因为这些公司回购的股权多于其发行的。

Overall, ongoing shareholders of smaller companies realize dilution, a reduction in their percentage of ownership, which means these companies issue more equity than they retire. Ongoing shareholders of large companies increase their ownership, on average, because these companies retire more equity than they issue.

我们的关注点放在那些在同时或短时间内大量发行和回购股票的公司上。如果股价与公允价值存在差异,无论发行还是回购股票,从理想资本配置的角度看,都不是最优选择。

Our focus is on companies that issue and retire substantial amounts of equity either simultaneously or within a short amount of time. If the stock price is any different than fair value, either issuing or retiring equity is suboptimal from the point of view of ideal capital allocation.

我们考察了 2021 年至 2023 年间,根据各公司股权的发行与回购情况,其股票为股东带来的总回报。我们将这些公司按发行与回购是否高于中位数,划分为四个象限。发行量以股权激励支出(SBC)除以销售额衡量,回购量以总回购金额除以市值衡量。

We examine the total shareholder returns from 2021 to 2023 for the stocks of the companies based on their issuance and retirement of equity. We separate the population into quadrants based on whether the companies are above or below the median for issuance and retirement. We measure issuance as SBC divided by sales and retirement as gross buybacks divided by market capitalization.

我们发现有少量股权激励发行和大量回购的公司,在各类分组中平均和中位的股东总回报(TSR)最高;而高股权激励、低回购的公司回报最低。高股权激励但同样有高回购的公司,其股票回报排名第三。我们得赶紧补充一句,许多与股权发行无关的因素,很可能对这些股东总回报起到了重要推动作用。

We find that companies with low SBC issuance and high buybacks delivered the highest average and median TSRs of the groups. Firms with high SBC and low buybacks produced the lowest returns. Returns for the stocks of companies that were high in SBC and buybacks had the third highest returns. We would hasten to add that numerous causes that had nothing to do with equity issuance were probably important in driving these TSRs.

这段讨论对希望审慎思考资本配置的董事会、管理层和投资者应当有所助益。从投资者的角度看,增发股票公司的股价回报平均而言低于标准,而回购股票的公司回报则颇具吸引力。对于那些同时增发又回购股票的公司,这两类信号相互交叉。假定管理层因比投资者掌握更多信息而能区分股价与价值,那么无论是增发还是回购,若未能实现,都偏离了资本配置的核心目标。55 那么,究竟是哪一种情况?

This discussion should be helpful for boards of directors, executives, and investors who seek to think carefully about capital allocation. From an investor’s point of view, the returns for the stocks of companies issuing stock have been substandard, and the returns have been attractive for those that retire stock, on average. Those signals cross for companies that issue and retire stock at the same time. Presuming that executives can distinguish between stock price and value because they have better information than investors do, either issuing or retiring fails to meet the central goal of capital allocation.55 Which one is it?
