Last week we looked at reasons for setting sustainable rates. The general idea was that a port or harbor facility should be bringing in enough revenue to cover expenses. Next week we’ll look at what expenses need to be included, but this week we’ll first consider different approaches to setting rates.
There are two general approaches to rate setting that we’ll consider here: market-based and economics-based. Arguably, there could be other categories to consider, but I find these two categories to be broad enough to cover most cases. As I’ll use them here, market-based rates are those driven by what users will pay and economics-based rates are driven more by the costs associated with a facility.
Market-based rate setting usually comes into play when there are two facilities located somewhat close to each other and with comparable offerings. Similarity can be based around many factors. For example, for commercial fishing vessels, similarity can be gauged based on proximity to the fishery resource. For transportation-focused facilities, proximity to major shipping routes and cargo-generating industries is important. For recreational vessels and activities centered on the land-water interface, then similarity may be judged by land access such as highways and railways, and the distances from, the use base to the facility. It’s very tempting to set rates based on one’s neighbors because (a) it’s an easy approach (i.e., fast and inexpensive), (b) it results in rates that users in the area are willing to pay, and© it results in a more acceptable rate from a political standpoint.
There is great danger, however, in using market-based rates without using some kind of economics-based approach to support the decision. Suppose Facility A wants to use rates currently in place at Facility B. Using the approach will work fine if Facility A and Facility B have identical costs, identical uses, and an identical user mix. This is rarely, if ever, the case, however, which means that Facility B’s rates won’t give Facility A the revenues it needs, or Facility B’s per-[gallon, ton, container, etc.] rate won’t be sufficient given the [gallons, tons, containers, etc.] handled at Facility A. In addition to the need for a perfectly-matched facility, using market-based rates also assumes that the owners of Facility B did their homework and set appropriate rates to begin with, not to mention follow an appropriate plan for rate increases over time.
This leads us to economics-based rates. As I’m considering them here, this category includes a broad range of tools and techniques used to create rate structures based on information specific to a facility. This can include the use of facility replacement costs, operating expenses, inflation adjustments, construction cost increases over time, and a facility’s historical usage and experience. Ideally, all of this factors will be considered, but rates based on even a subset of these factors will be more appropriate than purely arbitrary rates.
Since “economics-based rates” is a very broad term and can apply to many types of approaches to rate-setting, here is an example. A technique called Life Cycle Costing (LCC) evaluates the cost of a facility over its entire life. This is often done as part of an alternatives analysis; if everything else remains the same on the revenue side (i.e., the facilities provide the same functional capacity), you can look at the life cycle cost of each alternative that meets your needs and choose the one that has the lowest cost. In essence, this approach is the decision-making portion of value engineering.
When thinking about what costs should be included in a life cycle cost analysis, the answer is just about everything: startup costs, construction costs, operating costs, maintenance (both routine and major) costs, planned upgrades and other capital costs over time, and decommissioning costs. When plotted over time, these expenses show how a facility’s costs are distributed over its life. The timing of costs can vary considerably, which is the idea behind choosing higher quality (and cost) upfront in exchange for lower costs over time, reusability of older materials during decommissioning, and so on.
After considering all of the costs, life cycle costing uses the traditional Net Present Value technique to come up with the present value of future cash flows. The value can then be represented as a series of identical payments over time, similar to a mortgage payment. Converting from annual cash flows to the net present value and then to a series of uniform payments provides a single, smooth, annual amount that can be used to cover all costs over time.
While life cycle costing is just one of many economics-based techniques for rate setting, it serves as a good example of a tool that can be used when a great deal of information is available at the facility. Many other approaches exist under the “economics-based” umbrella and can be applied to different extents based on the amount of information available to make your rate decision.
In the context of life cycle costing, we’ve given a large list of costs that can be covered by rates. Next week, we’ll look at these expenses more closely and decide what needs to be included as part of the rate-setting process.
