How Risk Pooling Works
Risk pooling means a single employee’s cancer diagnosis or premature birth won’t devastate your budget. The captive absorbs these medium-to-large claims across all members, while stop-loss insurance handles true catastrophes.
What Is Stop-Loss Insurance and Why Do I Need It?
Stop-loss insurance protects your company from unexpectedly high medical claims by covering costs above predetermined limits, typically starting at $25,000-$50,000 per employee.
Two Types of Protection
Stop-loss insurance provides a critical safety net through two distinct coverage types.
Specific stop-loss coverage. Protects against individual high-cost claims by covering expenses above your chosen deductible per employee, typically $25,000 to $75,000.
Aggregate stop-loss coverage. Protects against higher-than-expected total claims by covering costs when your plan exceeds 125% of projected annual expenses.
Making It All Work: Your Third Party Administrator (TPA)
,Stop-loss insurance protects you from catastrophic claims, but who actually processes those claims, sends out ID cards, answers employee questions, and makes sure providers get paid on time?
That’s where your TPA comes in — the operational engine that makes self-funding work seamlessly.
Operational Components of a Self-Funded Captive Program
What Is a TPA and What Is Their Role In My Self-Funded Plan?
A third-party administrator (TPA) handles all day-to-day operations of your health plan, from processing claims to member services, so you can focus on running your business.
Core TPA Responsibilities
Your TPA serves as the operational backbone of your self-funded plan. They handle:
Claims processing. Your TPA processes medical claims, verifies coverage, negotiates provider payments, and delivers detailed spending analytics that reveal cost-saving opportunities.
Member services. Employees receive support through call centers, online portals, and ID card services with 24/7 access to benefits information, keeping your HR team free from daily benefits administration.
Plan administration. Your TPA creates plan documents, ensures compliance with ERISA and ACA regulations, manages enrollment changes, administers COBRA, and handles all government reporting so you can focus on your business.
Choosing the Right TPA Partner
Not all TPAs are created equal. Look for these differentiators:
Captive experience: Specialization in group captive administration.
Technology platform: Modern systems for claims processing and reporting.
Service metrics: Published standards for call times and claims turnaround.
Fee transparency. Clear per-employee-per-month pricing without hidden charges.
Integration capability. Seamless connectivity with stop-loss carriers and networks.
The Bywater Advantage
Roundstone’s in-house TPA, Bywater, was built specifically for captive administration:
No setup fees. Bywater charges no setup fees, even for groups under 50 employees.
99% claims accuracy. Claims are processed with 99% accuracy within our 14-day processing standard.
Transparent pricing. Bywater charges flat per-employee-per-month (PEPM) fees with no percentage-based charges.
Integrated operations. Bywater coordinates directly with Roundstone's captive management for seamless operations.
Dedicated service team. You work with consistent contacts who know your plan and your company's needs.
What Are Pharmacy Benefit Managers and How Do They Control Drug Costs?
While your TPA manages medical claims and plan administration, prescription drugs require specialized expertise through a Pharmacy Benefit Manager (PBM). Your PBM negotiates prescription drug prices, manages formularies, and processes pharmacy claims to control one of healthcare’s fastest-growing expenses.
What PBMs Do for Self-Funded Plans
Pharmacy Benefit Managers serve as the behind-the-scenes force controlling prescription drug costs, which typically represent 15-25% of total healthcare spending.
Here’s how they deliver value:
Price negotiation: PBMs secure discounts from drug manufacturers and pharmacies, often achieving 20-40% savings.
Formulary design: PBMs create preferred drug lists that guide employees toward cost-effective medications while maintaining quality.
Clinical programs: Advanced PBMs offer specialty drug management, prior authorization protocols, and step therapy programs that ensure appropriate medication use.
Rebate management: Unlike traditional insurance where carriers keep manufacturer rebates, self-funded plans retain 100% of these rebates.
Transparency Matters
Traditional PBM contracts often include hidden fees and spread pricing that benefit the PBM at your expense. Roundstone partners with transparent PBMs that pass through all savings and provide clear reporting on your pharmacy spend, ensuring every rebate dollar returns to your plan.

Self Funding and Benefits Advisors
Your benefits advisor serves as your strategic partner and guide throughout the self-funding journey. They help evaluate whether self-funding fits your company, assist with vendor selection, and provide ongoing support for plan optimization.
An experienced advisor who understands self-funding will help you navigate TPA selection, network choices, and stop-loss options while ensuring your plan design aligns with your budget and employee needs.
What Is Roundstone's Preferred Bundle?
Roundstone’s preferred bundle combines the Bywater TPA, Cigna network, and select pharmacy benefit managers to deliver optimal results. Groups using this strategic combination average $10,810 per employee annually – that’s $1,700 less than standard arrangements and 34% below industry benchmarks.
This integrated approach streamlines administration, maximizes pharmacy rebates, and provides data-driven cost optimization while maintaining gold-level coverage quality.
Breaking Down the Numbers
Recent data from the 2023 Mercer National Survey of Employer-Sponsored Health Plans shows the average employer with 50-499 employees spends $16,464 per employee per year (PEPY) on healthcare.
Roundstone’s internal performance data tells a different story:
Industry average: $16,713 per employee per year (PEPY)
Roundstone standard plans: $12,454 PEPY
Roundstone preferred bundle: $12,278 PEPY
Where Savings Come From
Self-funded savings come from multiple sources:
No insurance company profit margins. Traditional carriers build 15-20% profit into premiums.
Lower administrative costs. Transparent TPA fees versus hidden carrier charges.
Smarter spending. Data visibility enables targeted cost containment strategies.
Pharmacy rebates retained. You keep manufacturer rebates instead of the carrier.
Investment returns. Unused claims funds can be invested until needed.
The Roundstone Guarantee
We stand behind our promise: If you don’t save money within your first five years in the Roundstone group captive, we’ll make up the difference.
Two-thirds of our clients save enough in four years to pay for their fifth year of claims in full, and 100% keep the money they don’t spend.
Can I Customize My Self-Funded Health Plan?
Unlike one-size-fits-all traditional insurance, self-funding gives you complete control, with the flexibility to design benefits that match your employees’ needs and your budget. You’ll also get access to claims data so you can make informed cost containment decisions.
Plan Design Options
Self-funding puts you in control of every aspect of your health plan:
Financial parameters. Set deductibles, copayments, out-of-pocket maximums, and coinsurance levels that balance employee protection with plan sustainability and encourage smart healthcare utilization.
Coverage decisions. Customize what's covered, from 100% preventive care and expanded mental health benefits to alternative medicine options and prescription drug formularies that meet your employees' specific needs.
Network selection. Choose from national networks like Cigna or UnitedHealthcare, regional options with better local discounts, narrow high-performance networks, or negotiate direct contracts with health systems.
Strategic Design Approaches
Smart plan design goes beyond picking numbers. Self-funding lets you create incentives that guide employees to cost-effective care while improving their health outcomes.
Common strategies include steering employees to primary care with lower copays, eliminating costs for generic medications and preventive care, and offering free telemedicine visits.
You can also integrate advanced cost containment solutions like centers of excellence for major procedures and care navigation services.
Data Transparency Lets You Refine Your Design
When you self-fund, your claims data belongs to you. With Roundstone Reporting, you’ll see exactly where employees seek care, identify cost drivers, and track pharmacy utilization patterns.
This transparency lets you make annual refinements based on actual usage to create a continuous improvement cycle that enhances benefits while reducing costs.
Common Misconceptions About Self-Funded Insurance
The five biggest myths about self-funding are easily debunked by data from thousands of successful small and midsize businesses.
Myth 1: "Self-Funding Is Too Risky for Small Companies"
The myth: Only large corporations can handle the financial uncertainty of self-funding.
The reality: Group captives make self-funding as predictable as traditional insurance through:
Risk pooling across hundreds of employers
Stop-loss protection at multiple levels
Specific claim advance funding for cash flow protection
Twenty years of proven performance through all economic cycles
The proof: Over 1,000 companies with 25-1,000 employees successfully self-fund through Roundstone, with a 90% retention rate.
Myth 2: "It Costs More Than Traditional Insurance"
The myth: Self-funding leads to higher costs when claims spike.
The reality: Roundstone members consistently outperform traditional insurance:
Average savings of 24-34% versus industry benchmarks
Maximum exposure capped by stop-loss insurance
100% of unused funds returned to employers
The Roundstone Guarantee ensures savings within five years
The proof: Since 2003, Roundstone has returned $91.8 million in unused premiums to members.
Myth 3: "It's Too Complicated to Manage"
The myth: Self-funding requires extensive HR resources and expertise.
The reality: Your TPA handles all complex administration:
Claims processing identical to traditional insurance
Customer service for employee questions
Compliance with all regulations
Monthly reporting simplified through dashboards
The proof: HR’s role remains similar to traditional insurance—communication, enrollment support, and strategic planning.
Myth 4: "Level-Funding Is a Better Alternative"
The myth: Level-funded plans offer self-funding benefits with more predictability.
The reality: Level-funding is “self-funding lite” with significant drawbacks, including limited plan design and vendor choices. Level funding is often more expensive than true self-funding, as carriers keep 50-75% of the surplus.
The proof: Roundstone returns 100% of surplus, offers complete flexibility, and costs less than level-funded alternatives.
Myth 5: "We Could Get Dropped or Non-Renewed"
The myth: Poor claims experience leads to cancellation.
The reality: Roundstone guarantees renewals with no “adverse selection” exits. As a commitment to long-term partnerships, renewal proposals are provided to all members, and we offer support for high-cost situations through care management.
The proof: Unlike traditional carriers or other captives, Roundstone has never forced a group to leave due to claims.

Frequently Asked Questions About Self-Funding
A: With traditional insurance, you pay fixed premiums whether you use services or not, and the carrier keeps any surplus as profit. With self-funding, you pay only for actual healthcare usage and keep 100% of the savings. You also gain complete transparency into claims data and full control over plan design.
A: A group captive is a form of self-insurance where multiple employers pool resources to share risk. This makes self-funding affordable and predictable for companies with 25-1,000 employees by spreading risk across hundreds of businesses. Each member maintains their own plan design while benefiting from the group’s collective buying power.
A: Yes, through group captives. By pooling with other businesses and purchasing stop-loss insurance, companies with as few as 25 employees can self-fund as safely as Fortune 500 companies. The captive structure provides three layers of protection against unexpectedly high claims.
A: Stop-loss insurance limits your financial risk by covering claims above certain thresholds. Specific stop-loss covers individual high-cost claims (like cancer treatment) above your deductible, typically $25,000-$75,000. Aggregate stop-loss protects against higher-than-expected total claims, usually kicking in at 125% of projected costs.
A: A third-party administrator (TPA) manages your health plan operations including claims processing, member services, ID cards, provider networks, and regulatory compliance—everything an insurance carrier would handle internally. They process claims within 14 days, answer employee questions, and provide detailed reporting on your plan’s performance.
A: The preferred bundle includes Bywater (Roundstone’s in-house TPA), Cigna network access, and select pharmacy benefit managers (True Rx, Serve You Rx, or Cigna). This combination delivers the lowest costs—$10,810 PEPY versus $16,464 industry average—while maintaining gold-level coverage quality.
A: No, you’re free to choose any qualified TPA, network, and PBM. However, groups using our preferred bundle (Bywater + Cigna + select PBMs) average $1,700 less per employee per year compared to other arrangements. Your advisor can help you evaluate which approach works best for your situation.
A: PEPY (Per Employee Per Year) is the total annual healthcare cost divided by enrolled employees. It’s the key metric for comparing healthcare costs across different plans and company sizes. Lower PEPY means better cost efficiency. Roundstone’s average PEPY is $10,810-$12,385 versus the industry average of $16,464.
A: Roundstone members save 24-34% compared to traditional insurance. The average employer saves $4,079-$5,654 per employee annually. Many save enough in four years to fund their entire fifth year. A 100-employee company typically saves $400,000-$565,000 per year.
A: In Roundstone’s model, 100% of unused claims funds are returned to employers in cash approximately 6-7 months after the plan year ends. Traditional insurance keeps these funds as profit. Since 2003, Roundstone has returned $91.8 million to members.
A: If you don’t save money within your first 5 years in the captive, Roundstone will pay you the difference in cash. This guarantee reflects confidence in the model based on 20 years of proven results. It’s the only guarantee of its kind in the industry.
A: Implementation typically takes 30-45 days, similar to changing traditional carriers. This includes finalizing plan design, setting up administrative systems, creating employee communications, and conducting enrollment. The process is well-defined with your TPA and advisor guiding each step.
A: No. Your TPA handles all complex administration including claims processing, compliance, and reporting. HR’s role remains similar to traditional insurance: supporting employees, managing enrollment, and working with your benefits advisor on strategy. The main difference is you have data to make informed decisions.
A: Most likely, yes. Roundstone works with major national networks (Cigna, Aetna, UnitedHealthcare) and many regional networks. During implementation, we verify that your employees’ key providers remain in-network. You can also change networks annually if needed, unlike with traditional insurance.
A: Stop-loss insurance protects against high-cost claims, and the captive pools medium-sized risks across all members. Additionally, Roundstone provides care management resources to help control costs for complex conditions. Unlike traditional insurance, you won’t face huge renewal increases—just appropriate stop-loss adjustments.
A: Many employers see immediate monthly cash flow improvements since you only pay for actual claims plus fixed costs. Surplus accumulates throughout the year if claims run favorably. First-year distributions typically occur 6-7 months after your plan year ends, with ongoing savings continuing each year.
