California public agencies hear three financing structures discussed at conferences and in board meetings: municipal bonds, direct lease-purchase agreements, and Certificates of Participation. Most business officers understand bonds and leases. COPs sit in a middle ground that is less familiar but highly relevant for mid-size to large capital projects.
This article explains what a Certificate of Participation is, how it differs from bonds and direct leases, and when a California school district, city, or special district should consider using one.
What Is a COP?
A Certificate of Participation, or COP, is a financing structure in which investors purchase certificates that represent a fractional interest in the lease payments made by a public agency. Rather than lending directly to the agency, investors buy certificates through a trust or indenture trustee, and the trustee collects lease payments from the agency and distributes them to certificate holders.
The public agency does not issue debt in the traditional sense. Instead, it enters into a lease agreement with a trust or financing authority, and the trust sells participation certificates to investors to raise the capital. The certificates are typically tax-exempt municipal securities, meaning investors receive federally tax-exempt interest income.
The name is literal: certificate holders participate in the revenue stream from the lease. They do not own the asset, and they do not have a direct claim against the agency. Their recourse is to the trust, which holds the lease and the asset.
How COPs Work
The mechanics of a COP transaction follow a standard sequence:
- A public agency identifies a capital need (a new building, a fleet, or equipment) and determines that a COP structure is appropriate.
- The agency creates or works with an existing joint powers authority, public facilities corporation, or similar entity to serve as the lessor.
- The agency and the lessor enter into a lease agreement under which the lessor acquires or constructs the asset and leases it back to the agency.
- The lessor sells COPs to investors through an underwriter or placement agent. The proceeds fund the asset acquisition.
- The agency makes periodic lease payments to the lessor or a trustee, who distributes payments to certificate holders.
- At the end of the lease term, the agency typically exercises a nominal purchase option ($1 or similar) and takes title to the asset.
The key legal feature is the annual appropriation requirement. Like a direct lease-purchase, the agency's obligation to pay is subject to annual budget appropriation. This preserves the tax-exempt status and complies with California constitutional debt limits.
COP vs Bond vs Direct Lease-Purchase
| Factor | Municipal Bond | Direct Lease-Purchase | Certificate of Participation |
|---|---|---|---|
| Voter Approval | Required (55% or 2/3) | Not required | Not required |
| Investor Base | Institutional and retail | Single bank or funder | Multiple certificate holders |
| Deal Size | $5M+ typical | $250K to $5M typical | $3M to $50M+ typical |
| Issuance Cost | 1.5% to 3.5% | 1% to 2% | 1.5% to 3% (underwriter, trustee, counsel) |
| Flexibility | Low (rigid indenture) | High (negotiable terms) | Moderate (trustee governed) |
When COPs Make Sense
COPs are not the right tool for every project. They make sense in specific circumstances:
- Larger projects: COPs become efficient around $3 million to $5 million, where direct lease-purchase funders may not have capacity or appetite, but a bond is still overkill.
- Investor diversification: Because COPs are sold to multiple investors, the agency can access a broader capital market than a single-bank lease.
- Broader capital needs: A district undertaking a multi-year, multi-campus facilities program may use a COP to create a pooled financing vehicle that draws as projects are approved.
- Credit enhancement: COPs can be structured with reserve funds, bond insurance, or letters of credit that improve the rating and lower the interest rate.
- Joint projects: When multiple agencies collaborate on a shared facility, a COP issued through a joint powers authority can pool credit and share cost.
COPs are particularly common in California community college districts and large unified school districts that have outgrown direct lease-purchase capacity but want to avoid voter-approved debt.
California-Specific COP Considerations
California has a well-developed infrastructure for COP issuance. Many school districts work with the California Municipal Finance Authority (CMFA) or county-level financing authorities to serve as the lessor/JPA entity. These authorities provide standardized documents, pre-existing legal opinions, and access to underwriters familiar with California municipal law.
The annual appropriation requirement is enforced strictly. California courts have upheld the validity of COP structures where the lease payments are subject to annual appropriation, but they have struck down structures that attempt to create long-term debt without voter approval. The documents must be precise.
California also imposes disclosure requirements on COP issuers. While not as extensive as SEC Rule 15c2-12 for bonds, large COP offerings often require continuing disclosure through EMMA or a designated information agent. Business officers should budget for ongoing disclosure compliance.
Sample Structure: $5M Multi-Agency Facility
Consider three adjacent California elementary school districts that agree to build a shared maintenance and transportation facility:
- Total project cost: $5,200,000
- Each district's share: approximately $1,733,000
- The districts form a joint powers authority under California Government Code Section 6500 et seq.
- The JPA issues COPs through a regional underwriter.
- Term: 15 years
- Interest rate: 3.85% fixed (slightly higher than a GO bond but lower than direct lease-purchase for this size)
- Annual payment per district: approximately $173,000
- Each district appropriates its share annually through its respective board.
The COP structure allows the districts to share the facility cost without any single district carrying the full obligation, and without any district going to voters. The JPA owns the facility during the lease term, and the districts purchase it for $1 at the end.
Risks and Downsides
COPs are not without drawbacks. Agencies should understand these risks before choosing the structure:
- Complexity: COPs require more legal documentation, trustee involvement, and investor relations than direct leases. The timeline is longer and the staff burden is higher.
- Disclosure requirements: Depending on the offering size and structure, COPs may require continuing disclosure, annual audits, and material event notices. These obligations persist for the life of the certificates.
- Market risk: If the COP is sold on a negotiated rather than competitive basis, the agency relies on the underwriter's pricing. In volatile markets, that pricing can move against the agency between commitment and closing.
- Reserve fund requirements: Many COP structures require a debt service reserve fund equal to one year's maximum payment. That reserve must be funded at closing, increasing the total cash need.
- Less flexibility: Once issued, COPs are harder to refinance or prepay than direct leases. Call provisions, if any, are typically limited and may carry penalties.
For these reasons, COPs are best viewed as a middle-market tool: more scalable than direct leases, but more complex and less flexible. They shine in multi-agency, multi-year, or large single-project contexts where direct lease funders cannot provide the capital required.
