1. What Is Best Efforts Underwriting?#

Best efforts underwriting is a contract between an issuer (a company, government, or organization raising capital) and an underwriter (a financial institution like an investment bank) where the underwriter promises to use reasonable diligence to sell as many securities as possible—without guaranteeing a full sale.

1.1 Defining "Best Efforts" in Finance#

The term “best efforts” comes from contract law, where it requires a party to act in good faith and exert reasonable (not extreme) effort to fulfill a obligation. In finance, this translates to:

• The underwriter dedicates time, resources, and expertise to market the offering.
• The underwriter does not purchase unsold securities or take on inventory risk.

For example: If an issuer offers 1 million shares via best efforts, the underwriter might sell 800,000—and return the remaining 200,000 to the issuer. The underwriter earns a fee only on the 800,000 sold shares.

1.2 Core Principle: Good Faith, Not Guarantee#

The line between “best efforts” and “guaranteed sales” is critical. Underwriters are not required to:

• Discount shares heavily to move inventory.
• Use aggressive tactics (e.g., pressuring investors) to meet targets.
• Take on debt to buy unsold securities.

Instead, they must:

• Conduct a bona fide marketing campaign (e.g., roadshows, investor outreach).
• Communicate transparently with the issuer about demand.
• Honor the terms of the agreement (e.g., offering price, timeline).

This distinction protects underwriters from excessive risk while ensuring issuers get a fair shot at raising capital.

2. How Does Best Efforts Underwriting Work?#

The process follows a structured, transparent workflow. Let’s break it down step by step:

2.1 Step 1: Agreement Execution#

The issuer and underwriter sign a best efforts agreement that outlines:

• The total number of securities offered (e.g., 1 million shares).
• The offering price (e.g., $10 per share).
• The underwriter’s fee (typically 3–7% of sold securities).
• The subscription period (how long investors have to buy—usually 1–3 weeks).
• Termination clauses (e.g., if sales fall below a minimum threshold).

This contract is legally binding: The underwriter must fulfill its “best efforts” obligation, and the issuer must pay the fee for sold securities.

2.2 Step 2: Marketing Launch#

The underwriter initiates a marketing campaign to generate investor interest. Tactics include:

• Roadshows: In-person or virtual presentations to institutional investors (e.g., hedge funds, pension funds).
• Investor Outreach: Targeting retail investors via brokerage platforms or financial advisors.
• Disclosure Documents: Filing a prospectus (required by the SEC) that details the issuer’s financials, risks, and use of proceeds.

Unlike firm commitment underwritings, the underwriter rarely discounts shares upfront—since they’re not on the hook for unsold inventory.

2.3 Step 3: Subscription Period#

During the subscription period (1–3 weeks), investors submit orders to buy securities. The underwriter:

• Tracks demand in real time (e.g., “We’ve sold 500,000 shares so far”).
• Adjusts marketing tactics (e.g., targeting niche investors if institutional demand is low).
• May set a minimum sales threshold (e.g., 50% of shares sold) to proceed with the offering.

If demand is weak, the underwriter might extend the subscription period—or cancel the offering entirely (with the issuer’s approval).

2.4 Step 4: Closing and Settlement#

Once the subscription period ends:

1. The underwriter tallies all valid investor orders.
2. The issuer delivers the sold securities to investors.
3. The underwriter transfers the net proceeds (total sales minus fees) to the issuer.
4. The underwriter returns unsold securities to the issuer (no money changes hands for these).

For example: If 800,000 shares are sold at $10 each ($8 million total), and the underwriter’s fee is 5%, the issuer receives $7.6 million ($8 million – $400,000 fee). The remaining 200,000 shares stay with the issuer.

3. Best Efforts vs. Firm Commitment Underwriting: Key Differences#

Best efforts is one of two main underwriting models—the other is firm commitment. The table below highlights their critical differences:

Example: A startup using best efforts might raise $4 million from 800,000 shares sold. A Fortune 500 company using firm commitment would raise$10 million regardless of demand—even if the underwriter has to sell the remaining 200,000 shares at a loss.

4. Real-World Examples of Best Efforts Underwriting#

Let’s make the concept tangible with three real-world scenarios:

4.1 Example 1: A Tech Startup’s Seed IPO#

A pre-revenue AI startup wants to raise $5 million by selling 1 million shares at$5 each. No investment bank will offer a firm commitment—too much risk of low demand. Instead, the startup partners with a regional underwriter for best efforts.

• Marketing: The underwriter hosts virtual roadshows for angel investors and venture capital firms, highlighting the startup’s proprietary AI algorithm.
• Sales: By the end of the 2-week subscription period, they’ve sold 800,000 shares ($4 million).
• Outcome: The startup uses $4 million to hire engineers. The remaining 200,000 shares are held for a future offering. The underwriter earns a 6$240,000).

4.2 Example 2: Municipal Bond Offering for a Small City#

A small Midwestern city needs $10 million to renovate its public library. The city’s finance team opts for best efforts because municipal bond demand is volatile in rural areas.

• Marketing: The underwriter targets local banks, credit unions, and individual investors (e.g., retirees looking for tax-exempt income).
• Sales: They sell $8.5 million worth of bonds—enough to cover the library’s core renovations (e.g., new roofing, HVAC).
• Outcome: The city holds the unsold $1.5 million in bonds for a future offering when demand is stronger.

4.3 Example 3: Secondary Offering for a Niche Biotech Firm#

A biotech company with a promising but unapproved cancer drug wants to raise $20 million via a secondary offering. Institutional investors are wary of regulatory risk, so the company uses best efforts.

• Marketing: The underwriter targets specialized biotech hedge funds and accredited investors (individuals with over $1 million in assets).
• Sales: They sell $15 million in shares—enough to fund Phase III clinical trials.
• Outcome: The unsold $5 million remains with the company, avoiding dilution from forced sales (e.g., selling shares at$3 instead of $5).

5. Advantages of Best Efforts Underwriting#

Best efforts offers unique benefits for both issuers and underwriters:

5.1 For Issuers#

• No Inventory Risk: The issuer keeps unsold securities—no need to accept below-market prices or have the underwriter dump shares.
• Lower Cost: Fees are tied to sales. If the offering underperforms, the issuer pays less.
• Flexibility: The underwriter can adjust marketing tactics (e.g., targeting niche investors) in real time.
• Control: The issuer retains ownership of unsold securities, avoiding dilution (e.g., not having to sell shares at a loss to meet capital goals).

5.2 For Underwriters#

• Reduced Risk: No obligation to buy unsold securities—protecting the underwriter’s balance sheet.
• Reputational Control: If sales are low, the underwriter can argue they exerted “best efforts”—unlike firm commitment, where poor sales reflect directly on their judgment.
• Scalability: Underwriters can take on multiple best efforts deals simultaneously (since they don’t tie up capital in inventory).

6. Disadvantages of Best Efforts Underwriting#

While flexible, best efforts has tradeoffs:

6.1 For Issuers#

• No Capital Guarantee: The biggest downside—there’s no promise of raising full capital. A startup needing $5 million might only raise$3 million, derailing growth plans.
• Marketing Burden: The issuer may need to participate more in investor outreach (e.g., attending roadshows) since the underwriter has less skin in the game.
• Liquidity Risks: Unsold shares mean fewer traded securities—investors may face wider bid-ask spreads or difficulty selling.
• Reputational Risk: A poorly performing offering (e.g., 50% sold) can signal weak investor confidence, hurting the issuer’s future fundraising.

6.2 For Underwriters#

• Lower Fees: If sales are low, the underwriter earns less than in a firm commitment. For example: A 5% fee on $4 million in sales ($200,000) vs. a 3% fee on $10 million in firm commitment sales ($300,000).
• Resource Intensity: The underwriter must spend time and money marketing the offering—even if sales are low.
• Client Disappointment: Issuers may blame the underwriter for poor sales, damaging long-term relationships.

7. When to Choose Best Efforts Underwriting (and When to Avoid It)#

Best efforts is not a one-size-fits-all solution. Use it if:

7.1 Ideal Scenarios#

1. Risky Issuers: Startups, early-stage companies, or firms in volatile industries (e.g., crypto, biotech) where demand is uncertain.
2. Uncertain Demand: Offerings in niche markets (e.g., a solar farm in a rural area) or with limited investor awareness.
3. Secondary Offerings: Issuers that want to raise capital without diluting existing shareholders (e.g., selling 10% of shares instead of 100%).
4. Small Offerings: Raising less than $10 million—firm commitment underwriters rarely take on small deals.

7.2 Unsuitable Scenarios#

1. Established Companies: If you’re a Fortune 500 company with predictable demand (e.g., Apple), firm commitment is better—you need guaranteed capital.
2. Time-Sensitive Capital Needs: If you need $10 million *immediately* to pay debt or acquire a competitor, best efforts is too risky (you might only raise$7 million).
3. Large Offerings: For billion-dollar IPOs (e.g., Meta, Uber), firm commitment is standard—best efforts can’t generate the scale needed.
4. Regulatory Pressures: If your industry requires strict capital requirements (e.g., banks), best efforts’ lack of guarantee is a liability.

8. Key Insights for Issuers, Investors, and Underwriters#

Whether you’re raising capital, investing, or underwriting, these tips will help you navigate best efforts:

8.1 For Issuers: Maximizing Success#

• Vet Underwriters: Choose an underwriter with expertise in your industry (e.g., a biotech-focused bank for a drug developer). They’ll know how to target the right investors.
• Set Realistic Targets: Don’t overestimate demand. Use market research (e.g., surveys of potential investors) to set a feasible offering size.
• Negotiate Fees: Tie the underwriter’s fee to performance (e.g., 5% for sales below $4 million, 7$4 million). This aligns their incentives with yours.
• Prepare for Underperformance: Have a backup plan (e.g., a line of credit) if sales fall short.

8.2 For Investors: What to Watch For#

• Demand Signals: Low sales in a best efforts offering may indicate weak investor confidence. Do extra due diligence (e.g., read the prospectus) before buying.
• Liquidity: Unsold shares mean fewer traded securities—expect wider bid-ask spreads (e.g., buying at $5, selling at$4.80) and slower trade execution.
• Pricing: Underwriters rarely discount shares in best efforts. You’re more likely to pay the full offering price (e.g., $10 per share) than in firm commitment.
• Risk: Best efforts offerings are often for risky issuers. Only invest if you’re comfortable with potential losses.

8.3 For Underwriters: Mitigating Risk#

• Demand Assessment: Conduct thorough market research (e.g., surveying institutional investors) before agreeing to a best efforts deal. Avoid overpromising to the issuer.
• Transparent Communication: Keep the issuer updated on demand (e.g., weekly sales reports). If demand is weak, adjust tactics together (e.g., extending the subscription period).
• Limit Costs: Don’t overspend on marketing. For example: If the maximum fee is $240,000 (6$4 million), cap marketing expenses at $50,000 to ensure profitability.
• Reputation Management: Be honest with the issuer about their chances of success. A “no” to a bad deal is better than a failed offering that hurts your reputation.

9. Conclusion#

Best efforts underwriting is a risk-sharing tool that balances the needs of issuers (control over unsold securities) and underwriters (limited liability). It’s ideal for startups, small cities, and niche firms—but not for established companies needing guaranteed capital.

By understanding:

• How the process works,
• The differences from firm commitment,
• Real-world examples,
• Advantages and disadvantages,

You’ll be able to make informed decisions about whether best efforts is right for you.

For issuers: It’s about trading a guarantee for flexibility.
For investors: It’s about reading between the lines of demand.
For underwriters: It’s about leveraging expertise without taking on unnecessary risk.

At its core, best efforts is about good faith—and that’s what makes it a valuable tool in the world of finance.
