Alternative Investments · Investments in Private Capital: Equity and Debt

MODULE 78.1: PRIVATE CAPITAL

LOS 78.a

Explain features of private equity and its investment characteristics.

Private capital is the funding provided to companies that is not raised from the public markets. Private capital includes private equity and private debt.

Private equity is equity capital raised from sources other than the public markets. Private equity funds usually invest in private companies, or in public companies that they plan to take private (leveraged buyout funds), or in early-stage companies (venture capital funds). The companies in which a private equity fund invests are called its portfolio companies.

中文翻譯

私人資本（Private Capital）係指非透過公開市場募集、提供給企業的資金，包含私募股權（Private Equity）與私募債權（Private Debt）兩大類。

私募股權是來自公開市場以外的股權資金。私募股權基金通常投資於：未公開發行的私人公司、計劃由公開轉為私有的上市公司（槓桿收購基金），或處於早期階段的新創公司（創投基金）。被基金投資的公司稱為其投資組合公司（portfolio companies）。

Private Equity Investment Categories

A popular type of private equity fund is the leveraged buyout (LBO) fund, which acquires public companies with a large percentage of the purchase price financed by debt. LBOs are a way for a company to "go private" because after the transaction, the target company's stock is no longer publicly traded.

In an LBO, the private equity firm seeks to add value by improving or restructuring the portfolio company's operations to increase its sales, profits, and cash flows. The cash flows can then be used to service and pay down the debt taken to fund the acquisition.

Two of the various types of LBOs are:

Management buyouts (MBOs) — the portfolio company's existing management team participates in the purchase.
Management buy-ins (MBIs) — the private equity manager replaces the portfolio company's current management team with a new team.

教授提醒

記住區分方法：MBO 是「自己人買」（原管理層續任並參與收購），MBI 是「外人進來」（私募基金引進新管理團隊取代原團隊）。兩者皆屬於 LBO 的一種型態。

私募股權的投資類型

槓桿收購基金（LBO Fund）是最常見的私募股權基金類型，以高比例的債務融資收購上市公司。LBO 是公司「下市」（go private）的途徑之一，交易完成後標的公司股票不再公開交易。

在 LBO 中，私募基金透過改善或重整投資組合公司的營運（提高銷售、利潤與現金流）來創造價值；產生的現金流接著用以支付收購所舉借的債務本息。

LBO 的兩個主要型態：

管理層收購（MBO）：原有管理團隊參與收購（繼續經營公司）。
管理層接管（MBI）：私募基金引進新團隊取代原管理層。

Venture capital (VC) funds provide financing to companies in the early stages of their development. VC funds typically receive common equity interest in the portfolio companies, but they may also get convertible debt or convertible preferred stock. Convertible securities help to align the interests of the VC investors and the start-up firm — both want to increase the value of the firm — but give the VC investors a higher priority of claims in the event of liquidation.

VC investment involves a high level of risk, but the returns can be substantial. VC investors are actively involved in developing their portfolio companies, often sitting on the boards or filling key management roles.

VC investments can be classified by the portfolio company's stage of development:

Formative stage — investments made during a firm's earliest period; comprises three phases:
- Pre-seed capital / angel investing — capital provided at the idea stage. Funds are used for business plans and assessing market potential. Amounts are usually small and come from individual "angels" rather than VC funds.
- Seed-stage financing — generally supports product development, marketing, and market research. This is the first stage at which VC funds usually invest.
- Early-stage / start-up financing — investments made to fund operations leading up to production and sales.
Later-stage financing (expansion venture capital) — comes after production and sales have begun. Used for initial growth, expansion, product improvement, or marketing. In this stage, the owners (typically the founders/managers) often sell control of the company to VC investors.
Mezzanine-stage financing — capital provided to prepare the firm for an initial public offering (IPO). The term mezzanine stage indicates the timing of the financing rather than the method. The similar term mezzanine financing refers to hybrids of equity and debt (such as convertible securities); mezzanine-stage financing can use these but more often consists of equity or short-term debt.

教授提醒

考點易混淆：「夾層階段（mezzanine stage）」指的是融資時機（IPO 前），不是融資工具類型。「夾層融資（mezzanine financing）」才是指股債混合工具（可轉債等）。兩者名稱相似但意義不同。VC 基金第一次投入通常在 seed stage（種子期），不是 angel 階段。

中文翻譯

創投基金（VC Fund）提供資金給處於早期發展階段的公司。VC 基金通常取得普通股，但也可能取得可轉換債券或可轉換特別股。可轉換證券能對齊 VC 投資人與新創公司的利益（雙方都希望公司增值），同時讓 VC 在公司清算時享有較高的求償順位。

VC 投資風險高，但報酬可能極為可觀。VC 投資人積極參與被投資公司的發展，通常會擔任董事或核心管理職務。

VC 投資可依被投資公司發展階段分類：

形成期（formative stage）：包含三個子階段：
- 天使投資（pre-seed / angel）：構想階段提供資金，用於商業計畫與市場潛力評估，金額通常較小，來自個人「天使」而非 VC 基金。
- 種子期（seed-stage）：支持產品開發、行銷與市場研究。VC 基金通常從這個階段開始投入。
- 早期／創業期（early-stage / start-up）：用於量產與銷售前的營運資金。
後期擴張（later-stage / expansion VC）：已開始量產銷售後的資金，用於初步成長、擴張、產品改善或行銷。此階段創辦人/經營者常將公司控制權讓給 VC 投資人。
夾層階段（mezzanine-stage）：為 IPO 做準備的資金。「夾層階段」指時機而非方法；類似名詞「夾層融資（mezzanine financing）」則指股債混合工具（如可轉換證券）。夾層階段融資可使用這些工具，但更常見的是股權或短期債務。

A private equity firm that engages in minority equity investing buys a less-than-controlling interest in public companies that are looking for capital with which to expand. One way it can make such investments is through a private investment in public equity (PIPE) — a private offering to institutional investors that allows a publicly traded firm to raise capital more quickly and cost-effectively than a public offering, with fewer disclosures and lower transaction costs.

中文翻譯

從事少數股權投資（minority equity investing）的私募基金，會以非控制性比例投資於想擴張的上市公司。其中一種方式為上市公司私募股權投資（PIPE）——上市公司向機構投資人私下發行股票，可比公開發行更快、更便宜地募資，揭露要求與交易成本也較低。

Private Equity Exit Strategies

Private equity firms typically add value to young companies, then sell them, with an average holding period of five years. Funds have several methods of exiting an investment in a portfolio company:

Figure 78.1: Five PE Exit Methods

Exit Method	Key Features
1. Trade sale	Sell to a strategic buyer (often a competitor) via direct sale or auction. Strategic buyers typically pay a premium to capture synergies. Pros vs. IPO: faster execution, lower transaction costs. Cons: potential resistance from portfolio company management/employees; limited universe of potential buyers.
2. Public listing	Listing on a stock exchange via IPO, direct listing, or SPAC (see detail below).
3. Recapitalization	The company issues debt to fund a dividend distribution to equity holders. Not technically an exit (the fund still controls the company), but it allows the PE fund to extract money to pay its investors.
4. Secondary sale	Sell the portfolio company to another private equity firm or a group of investors.
5. Write-off / liquidation	Reassess and take losses from an unsuccessful investment in a portfolio company.

Public listing methods (detail):

IPO — the most common method, using investment banks to underwrite the offering. Usually realizes the highest price for the portfolio company; improves visibility (positive for retained shares). Drawbacks: high transaction and compliance costs; not always favorably received by the public. Best for large firms in growing industries with stable finances and clear strategies.
Direct listing — stock floated on the public market directly without underwriters. Lower cost than IPO, but does not raise new capital for the portfolio company.
Special purpose acquisition company (SPAC) — a "blank check" entity set up solely to raise capital, which it must use to acquire an unspecified private company within a stated time period (otherwise the capital is returned). Pros: more flexible than IPO; reduces valuation uncertainty; access to investors who transact regularly with sponsors. Cons: dilutive effects from SPAC shares and warrants; spread between SPAC value and acquired company value; deal risk; stockholder overhang from SPAC shareholders selling after the acquisition is announced; increasing regulatory scrutiny.

私募股權的退出策略

私募基金通常為年輕公司增值後再出售，平均持有期約五年。退出投資的五種方式：

同業出售（Trade sale）：賣給策略性買家（通常為同業）。策略買家為實現綜效常願付溢價。相對 IPO 的優點：執行較快、成本較低；缺點：可能遭到原管理層/員工反對，潛在買家有限。
公開上市（Public listing）：透過 IPO、直接上市或 SPAC 上市。
資本重組（Recapitalization）：公司舉債以發放股利給股東。嚴格而言不是退出（基金仍持有公司），但能讓 PE 基金把錢分配給投資人。
二級市場出售（Secondary sale）：將投資組合公司賣給另一家私募基金或投資人團體。
核銷／清算（Write-off / liquidation）：對失敗的投資進行減記與認列損失。

公開上市三種方法：

IPO：最常見，由投資銀行承銷；通常能取得最高價，並提升公司能見度。缺點：成本與合規負擔高，市場反應不一定理想。適合：規模大、產業成長、財務穩健、策略清晰的公司。
直接上市（Direct listing）：不經承銷商直接掛牌。成本較低，但不會為公司募集新資金。
SPAC（特殊目的收購公司／空白支票公司）：單純為募資設立的殼公司，必須在規定期限內收購一家未指定的私人公司，否則須退還資金。優點：較 IPO 彈性、估值不確定性較低、可接觸特定投資人。缺點：SPAC 股份與認股權證造成稀釋、SPAC 價值與被併購公司價值有價差、交易風險、SPAC 股東於宣布併購後賣股造成的「股東 overhang」、監管審查日益嚴格。

Risk and Return From Private Equity Investments

Empirical evidence shows that returns on private equity funds have been higher on average than overall stock returns. However, the standard deviation of private equity returns has been higher than that of equity index returns, suggesting higher risk, including illiquidity and leverage risks.

Furthermore, private equity indexes typically rely on self-reporting and are subject to survivorship bias and backfill bias, both of which lead to overstated returns. Because portfolio companies are revalued infrequently, measures of volatility and correlation with other investments may be biased downward.

教授提醒

典型偏誤要記牢：自我申報＋存活偏誤＋回填偏誤 → 報酬被高估；估值頻率低 → 波動度與相關性被低估。這兩組偏誤方向相反但都讓 PE 看起來「比實際好」。

中文翻譯

私募股權的風險與報酬

實證上，私募股權基金平均報酬高於整體股市，但其報酬標準差也高於股票指數，反映出較高風險，包括流動性風險與槓桿風險。

此外，私募股權指數通常仰賴業者自我申報，並存在存活偏誤（survivorship bias）與回填偏誤（backfill bias），兩者都會使報酬被高估。由於投資組合公司很少重新估值，因此波動度與其他資產的相關性常被低估。

LOS 78.b

Explain features of private debt and its investment characteristics.

Private debt refers to various forms of debt provided by investors directly to private entities. The main categories are:

Figure 78.2: Categories of Private Debt

Category	Description
1. Direct lending	Loans made directly to a private company without an intermediary. Debt is typically senior and secured, with covenants to protect the lender. A leveraged loan is a loan made by a private debt fund using money borrowed from other sources — i.e., the fund's portfolio of loans is leveraged to magnify returns.
2. Venture debt	Funding provided to VC-backed start-ups or early-stage firms that are not yet profitable. Often convertible to stock or combined with warrants. Young-company managers may favor venture debt because it lets them maintain ownership and control.
3. Mezzanine debt	Private debt subordinated to senior secured debt. May have special features such as conversion rights or warrants to compensate investors for additional risk.
4. Distressed debt	Debt of mature companies in financial trouble (bankruptcy or default). The fund often actively restructures the debt or makes other changes to increase value. Some specialize in identifying otherwise good companies with temporary cash flow problems; others focus on turnaround situations and active management.
5. Unitranche debt	Combines different classes of debt (secured + unsecured) into a single loan with a blended interest rate. Typically ranks between senior and subordinated debt.

Private debt investments typically provide a higher rate of return than traditional bonds to compensate investors for higher risk and lack of liquidity. They may also offer diversification benefits, since private debt returns have relatively low correlations with traditional investments.

The interest rate of private debt is usually set relative to a reference rate, such as the Secured Overnight Financing Rate (SOFR). The rate therefore changes when the reference rate fluctuates due to changes in the interest rate environment.

Risks include illiquidity and default risk. Private debt investing requires specialized knowledge about the structure of the debt, the borrower's life-cycle phase, and the features of the underlying assets for secured lending. Senior private debt has less risk and steadier yields than mezzanine private debt, but mezzanine debt offers greater upside potential.

中文翻譯

私募債權（Private Debt）是投資人直接提供給未上市企業的各類債務。五大類別：

直接貸款（Direct lending）：不透過中介直接借款給私人公司，通常為高順位、有擔保且附契約條款。槓桿貸款（leveraged loan）是私募債權基金以借入資金所做的貸款——基金本身的貸款組合採槓桿操作以放大報酬。
創投債（Venture debt）：提供給 VC 投資的尚未獲利新創或早期公司，常具可轉股權利或搭配認股權證。新創管理層偏好創投債，因為能保留所有權與控制權。
夾層債（Mezzanine debt）：順位低於高順位有擔保債務的私募債，常附特殊條件（轉換權、認股權證）以補償較高風險。
不良債權（Distressed debt）：陷入破產或違約等財務困境的成熟公司之債務。基金常積極重組債務或推動變革來提升價值。一派專注於辨識基本面良好但暫時現金流困難的公司；另一派則收購公司債務後積極參與經營與重整（turnaround）。
單一順位債（Unitranche debt）：把不同順位的債務（有擔保 + 無擔保）合併為單一貸款，利率為混合利率，順位介於高順位與夾層債之間。

私募債權報酬通常高於傳統債券，以補償流動性差與較高風險；與傳統投資相關性較低，可提供分散化效益。利率通常以參考利率（如 SOFR）為基準浮動，會隨利率環境變動。

主要風險：流動性與違約風險。投資人需具備債務結構、借款人生命週期階段、擔保資產特徵的專業知識。高順位私募債風險較低、收益穩定；夾層債風險較高但有較大上行空間。

LOS 78.c

Describe the diversification benefits that private capital can provide.

Private capital investments can provide some diversification benefit to a portfolio of traditional investments. Empirical evidence indicates that correlations of private capital fund index returns with public market index returns range from 0.63 to 0.83.

Each private equity fund has a vintage year, which is the year the fund made its first investment. The performance of a fund is greatly influenced by its vintage year and the phase of the business cycle in that year:

Funds that begin investing during a business cycle expansion are likely to earn higher returns if they specialize in early-stage companies.
Funds that begin investing during business cycle contractions are likely to earn higher returns if they specialize in distressed companies.

Investors in private capital should diversify across vintage years.

Risk and return profiles vary among categories of private capital. From highest to lowest risk/return:

Private equity (highest)
Mezzanine debt
Unitranche debt
Senior direct lending
Senior real estate debt
Infrastructure debt (lowest)

教授提醒

Vintage year 與景氣階段的搭配是常考點：擴張期 + 早期創投、收縮期 + 不良債權，兩種搭配最容易賺超額報酬。風險報酬排序也可能直接出題：PE > Mezz > Unitranche > Senior direct > Senior RE debt > Infrastructure debt。

中文翻譯

私募資本可為傳統投資組合提供有限的分散化效益。實證上，私募資本指數與公開市場指數的相關係數約介於 0.63 ~ 0.83。

每檔私募基金都有一個起始年（vintage year），即該基金做第一筆投資的年份。基金績效受 vintage year 與當年景氣階段影響很大：

景氣擴張期開始投資的基金，若專注於早期階段公司，通常績效較佳。
景氣收縮期開始投資的基金，若專注於不良債權公司，通常績效較佳。

因此，私募資本投資人應跨 vintage year 做分散。

各類私募資本風險／報酬由高至低排序：私募股權 > 夾層債 > 單一順位債 > 高順位直接貸款 > 高順位不動產債 > 基礎建設債。

Module Quiz 78.1

1. In which stage of a firm's development is a venture capital fund most likely to make its initial investment?

A. Start-up.
B. Seed capital.
C. Angel investing.

B — VC funds typically make their initial investments during a firm's seed stage for product development, marketing, and market research. At the angel investing stage, the funding source is usually individuals rather than VC funds. The start-up (early) stage follows the seed stage and refers to investments made to fund initial commercial production and sales. (LOS 78.a)

2. In a secondary sale, a private capital firm sells one of its portfolio companies to:

A. the public.
B. a competitor in its industry.
C. another private capital fund.

C — In a secondary sale, a private capital firm sells one of its portfolio companies to another private capital fund or group of private investors. Selling a portfolio company to a competitor in its industry is known as a trade sale. Selling a portfolio company to the public requires an IPO. (LOS 78.a)

3. Unitranche debt is best described as:

A. combining different classes of debt into a single loan.
B. having special features, such as conversion rights or warrants.
C. a loan made by a private debt fund using money borrowed from other sources.

A — Unitranche debt refers to combining different classes of debt into a single loan with an interest rate that reflects the blend of debt classes. (B describes mezzanine debt features; C describes a leveraged loan.) (LOS 78.b)

4. Which type of private capital fund is most likely to earn excess returns over its life if its vintage year took place during an economic contraction?

A. Venture capital fund.
B. Distressed debt fund.
C. Leveraged buyout fund.

B — Funds with vintage years during contractions are likely to earn higher rates of return if they specialize in distressed companies. Funds with vintage years during expansions are likely to earn higher rates of return if they specialize in early-stage companies. (LOS 78.c)

Key Concepts — Reading 78

LOS 78.a

Private equity funds invest in the equity of private companies or companies wanting to become private, often financing assets with high levels of debt:

Venture capital funds provide capital to companies early in their development. Stages: formative (angel, seed, early), later/expansion, and mezzanine (prepare for IPO).
Leveraged buyouts include management buyouts (existing team participates) and management buy-ins (external team replaces existing management).
Developmental capital / minority equity investing provides capital for business growth or restructuring. For public companies, this is referred to as a private investment in public equity (PIPE).

Methods for exiting portfolio companies: trade sale, IPO (or direct listing / SPAC), recapitalization, secondary sale, or write-off / liquidation.

LOS 78.b

Private debt refers to lending to private entities. Categories: direct lending, venture debt, mezzanine debt, distressed debt, unitranche debt. Private debt investing requires specialized knowledge about the debt structure, the borrower's life-cycle phase, and the features of the underlying assets.

LOS 78.c

Private capital can provide some diversification benefit because correlations with traditional investments are relatively low (≈0.63–0.83).

Investors should diversify across vintage years. Funds with vintage years during expansions earn higher returns if they specialize in early-stage companies; funds with vintage years during contractions earn higher returns if they specialize in distressed companies.

Risk/return ranking (high → low): private equity > mezzanine debt > unitranche debt > senior direct lending > senior real estate debt > infrastructure debt.
