At a time when investors are cautious about the return outlook for traditional public markets, private equity offers important long-term advantages, including strong historical returns and diversification benefits.

Private Equity Basics

Private, Diverse:

  • Private equity (PE) is an investment in a company that is not listed on a public exchange.
  • PE-backed companies are a growing presence, found across a wide spectrum of business sectors and stages (i.e., in start-ups, middle market and well-established enterprises).

Truly Active:

  • PE managers have a greater ability to influence both the operations and management of a business.
  • Unlike a typical investor in public equity, PE investors can play a very active role in the management of its portfolio companies, and can thus dramatically improve its operating results.

The Private Equity Universe

Within private equity, there is considerable variety and thus diversification potential. Key areas of investment include:

Buyouts. Investment in relatively mature, established companies, using a combination of debt and equity financing. This group is divided into small-, mid- and large/mega-cap buyouts.

Special situations. Involves restructuring of companies both from a financial and operational standpoint, and may involve the purchase of distressed assets or debt.

Growth capital. Typically working in partnership with a founder or entrepreneur, the private equity investor provides capital to help a company grow.

Venture capital. Investment in new, potentially high-growth, businesses alongside company management. Venture-capital financed companies may carry more risk than the other private equity segments due to the early stage of the business.

Private Debt. Investment in middle market companies that provide fixed income returns capitalizing on the illiquidity premium.

Depending on the investor, a core allocation to private equity may complement other alternative investments, such as real estate and hedge funds.

Why PE Managers Have an Advantage

On the Buy:

  • Unlike public markets, a private market investor can have information advantages, such as access to management and greater visibility into a potential portfolio company.
  • Private equity is an inefficient market compared to public markets, and thus provides additional opportunities for attractive valuations.

During the Hold:

  • The private equity investor has the ability to influence a portfolio company for the better—both in terms of operating improvements and positioning the company for growth.

On the Sell:

  • PE investors have many potential exit options, including an IPO or sale of the portfolio company to a strategic or financial buyer.
  • Importantly, private equity investors have the luxury of time. They're not managing to quarterly earnings, and can choose to exit at the most attractive time.

Private Equity’s Performance Benefits

These PE advantages have historically translated into attractive performance and effective diversification. Private equity has outperformed the major public markets over the last 5-, 10-, 15- and 20-year periods with relatively low correlations to traditional asset classes. In addition, over the last 25 years, the addition of an allocation to private equity has provided an improved risk/return profile for diversified portfolios.

Key Considerations

Liquidity Risk: The process of making improvements to portfolio companies takes time—sometimes a lot of it—leading to liquidity risk. Private equity has lock-up periods, typically ranging from eight to 14 years. The tradeoff is that investors should be compensated for this illiquidity.

Return Patterns: The investor initially experiences negative cash flows as capital is “called” and put to work. The expectation is that returns become positive later as investments are harvested and cash is returned to investors..

Allocating to Private Equity


  • Neuberger Berman’s Investment Strategy Group typically recommends that high net worth investors with moderate to aggressive investor profiles invest up to 10% in private equity; individual needs vary—some may prefer to have more or less than this amount.

Systematic Approach:

  • To offset the initial dip in cash flows early in the PE cycle, investors may choose to regularly invest over multiple years.
    • This helps to diversify by “vintage” (the characteristics of each year’s funds may be somewhat different).
  • Investors often consider “overcommitting” to private equity to make sure they have sufficient assets at work.
    • Typically, a fund will have about 60% – 70% of capital commitments invested at any given time, suggesting the need to commit 1.2 to 1.5 times the amount you want invested in order to achieve the desired exposure to private equity.

Accessing Private Equity

There are multiple ways to access the asset class:

Primary fund investment. An investor makes a commitment to a private equity fund, which, via a general partner, makes investments into several companies. Here, there is more diversification of underlying holdings across the private equity portfolio.

Fund of funds. In this case, an investor makes a commitment to a vehicle or a fund that in turn makes commitments to individual private equity funds. These commitments are typically very diverse, with investments across managers and portfolio companies.

Secondary fund. In a secondary fund, the general partner buys more mature or seasoned limited partnership stakes from other limited partners, often at a discount.

Co-investment. The investor makes equity co-investment in an operating company, alongside the private equity manager, in a leveraged buyout, recapitalization, growth or venture capital transaction.

What to Look For in a PE Manager

There are about 17,000 private equity firms in the space, with a wide disparity in terms of investment success, style and strategy. We believe a successful manager should have the following characteristics:

Access to Opportunities, Information:

  • A PE manager should have access to a significant and wide array of attractive opportunities (or “deal flow”) in order to be highly selective.
  • The manager should be able to access information and resources needed to make well-informed investment decisions.

Experience and Resources:

  • A PE manager should have an experienced team with ample resources that has invested across multiple asset classes and market cycles.
  • The manager should have an attractive track record, both on an absolute basis and relative to peers. The strategy employed should not only have a history of success, but compare well in specific periods, given the market and economic environment.

Combining these elements will increase the chances of effectively accessing the unique opportunity associated with private equity.

Addendum: PE Nuts and Bolts

Who’s Who:

  • PE funds are typically structured as partnerships.
  • The general partner, or GP, controls the fund and makes investment decisions. A GP will also typically make a significant investment in the fund.
  • The Limited Partners, or LPs, are the investors.


  • The GP invests in companies with the idea of improving, growing and then selling them.
  • The GP makes capital calls from limited partners as it makes investments.
  • Once investment objectives tied to underlying portfolio companies are completed, it is sold and proceeds, subject to incentive allocations, are distributed back to the investors.


  • During the investment period, which typically lasts three to five years, the GP is looking for appropriate investment opportunities, and begins to call capital from LPs with which to invest.
  • The harvest or divestment period follows, which typically takes four to six years, in which private equity investments are developed and, ideally, realized. All told, the typical fund life is between eight and 14 years. Please also see “Private Equity Investment Cycle”.

Costs and Fees:

  • Although PE fund fees can vary widely, most private equity funds typically charge a management fee of 1% – 2% on committed capital, with an additional performance-related fee component or “carried interest.”
  • Carried interest serves as extra incentive for fund managers, is generally tied to fund performance and is often paid when returns exceed a certain threshold, called the “preferred return” or “hurdle.”

Tax Treatment:

  • Every PE fund has its own tax treatment depending on the type and mix of the underlying investments.
  • As funds are generally structured as limited partnerships, the income, gains and losses they produce flow directly to investors for tax purposes. For example, a venture capital fund might result in more taxable capital gains to investors while a private debt fund might generate more ordinary income.
  • It’s important to note that the tax treatment of these investments may affect whether they are suitable for use in an IRA, Roth IRAs or other tax-favored vehicles. Be sure to consult with a tax advisor before you invest.

Tax Reporting:

  • Private equity funds typically generate an annual Form K-1 for use in preparing income taxes, which typically take longer to produce—sometimes well after the mid-April tax deadline, which may require the taxpayer to file for an extension.
  • On the bright side, multiple K-1s can be “added together” when preparing income tax returns. Again, please consult with your tax advisor before making any investment.
