Public private partnership

A Venn Diagram of a Public Private Partnership (PPP)

Introduction

Most transit agencies engage in some form of public-private partnerships. An agency that engages with a private-sector firm to design or construct a transit plaza is engaging in a simple public-private partnership that distributes risk and responsibility between itself and private sectors to accomplish a project with a public benefit. Recently, as government has tightened its fiscal belt, transit agencies and other stakeholders have become interested in public-private partnerships as a means of attracting additional funding or accelerating project completion. However, public private-partnerships are often misunderstood. A public-private partnership must confer some benefit (usually a rate of return on capital) to the private sector partner.

Risk transfer

One argument in favor of a public-private partnership is that the arrangement allows the public sector to offload some risk related to project design, finance, construction, operations, and maintenance. Design-build contracts are popular because the structure allows a single party to manage risks related to designing and constructing an infrastructure project. Risks related to costs of constructing a specific design element or certain design flaws can be reduced. A design-build-operate-maintain contract can allow a single party to manage design and construction elements that may impact operation or maintenance costs, rather than allowing parties to transfer risk and costs to other parties. Public-private partnerships can create incentives for early project delivery or penalize late project delivery and transfer risk that fare revenues or other fees are less than expected due to lower than forecast ridership. Under certain arrangements where no revenue guarantee exists, the entity responsible for operating the transit facility will bear the risk of any shortfall in funds from operations.

Additionality

Public private partnerships can lead to investments in infrastructure that would have otherwise been delayed or not made at all. In these cases, the partnership provides an additional investment that would not be possible if the public sector were to rely solely on its own support. Engaging in a public private partnership that produces additional investment is not a choice between exclusive public support and a partnership with private support, but rather a choice between pursuing the investment under a private-sector partnership and not pursuing the investment at all.

Flexibility

Certain contracting arrangements better accommodate necessary adaptations to deal with unforeseen circumstances. Multi-year projects can face conditions that were not expected during the project planning and onset phases. For example, a multi-year subway construction project using a public-private partnership may be better able to take advantage of new tunnel boring technology than a contract in which the builder is restricted by certain design criteria.

Public-private partnership structures

Several permutations are possible to transfer tasks, responsibilities, risks, and ownership from the public to the private sector. These include:

• BOT - Build Operate Transfer
• BOOT - Build Own Operate Transfer
• BOO - Build Own Operate
• BLT - Build Lease Transfer
• DB - Design Build
• DBB - Design Bid Build
• DBFO - Design Build Finance Operate
• DBFMO - Design Build Finance Maintain Operate
• DCMF - Design Construct Manage Finance

Types of PPPs for Transit Agencies

In transportation, a public private partnership "involves one or more aspects of the funding, financing, planning, design, construction, operation and maintenance of a transportation facility" In practice, this can take several forms.

Contracting

Agencies use private sector contractors to provide some or all ancillary and core services. Contracting may range from purchasing (using an external printing company to print schedules), to contracting ancillary services (e.g. using an outside payroll company), to contracting transit operations - their core service. Agencies must evaluate ancillary and core service outsourcing on a case-by-case basis to understand what may gained and what may be lost.

Tolling

Although transit already levies a toll-for-service, many automobile facilities do not. Imposing a toll on a previously free facility used by automobiles can both generate revenues and demand for transit. Tolling is typically not politically popular, though providing something new in return for the toll can reduce opposition. Tolling can be used in a BOT, BOOT, DBFO, or DCMF arrangement to provide payments to a private-sector partner which contributed capital and expertise to develop the transportation facility. Tolling generates new revenues, and new revenues are often required to make a public private partnership feasible.

Financing

Private capital typically requires a higher rate of return than public capital. This is because dividends paid on municipal bonds are usually untaxed, and the private sector requires a profit margin while the public sector does not. Nevertheless, public private partnerships can bring new investment capital to a project that will produce new revenues or will increase the public entity's capacity to service debt or pay fees to the private sector partner. Using private financing can be a way for the public sector to move long-term liabilities off of their balance sheet.

Real Estate

Real estate developers can support transit indirectly through development projects that are supportive of transit. Such transit-oriented development bring not only additional ridership, but also additional political support for the transit system. Under a joint-development scenario, a transit agency works with the private sector to develop a publicly-owned parcel.

Public Perception of Public-Private Partnerships

Members of the public will likely perceive that the partnership grant profits to the private sector at the public's expense. A public relations strategy from an early stage should focus on how the partnership enables the project to be built more quickly or more completely under a partnership.

This postgraduate-level textbook is an in-depth resource for evaluating and entering into public private partnerships. It's a useful resource for someone with prior knowledge of transit capital project management or project finance who is considering various PPP structures and is seeking to evaluate risk transfer and rates of return.
