Case Description of City of Somerville:Using Activity-Based Budgeting to Improve Performance in the Somerville Traffic Unit Case Study

Since 2004, City of Somerville Mayor Joseph Curtatone has undertaken a series of fiscal reforms that have allowed the City to improve municipal services during financial hard times. A key reform has been the City's adoption of the budgeting approach called activity-based costing (ABC budgeting). With ABC budgeting, City officials have been able to make budgetary decisions based on detailed information about the expenses and revenues associated with discrete City activities. The transition to ABC budgeting from line-item budgeting that most municipalities use has not been easy, however.As first step, Somerville officials developed an inventory of the main programs of each of Somerville's 18 departments and the costs associated with each program. Calculating costs at the program level required a less detailed analysis than calculating costs at the activity level. They identified the activities associated with each program and established performance objectives for each activity. During the fall of 2004, HKS Prof. Linda Bilmes and her students helped Somerville officials accomplish these steps. Together, this information allowed officials and residents to understand for the first time how the City's expenditure of tax dollars translated directly into the City's delivery of services that constituents valued. Encouraged by the results, the Mayor asked Prof. Bilmes and her students to focus on a municipal activity of particular concern to officials and residents: traffic enforcement. Mayor Curtatone asked whether increasing enforcement of the City's traffic laws might pay for itself through increased citation revenue. The case walks through the steps Bilmes and her students took to determine the answer, including allocating personnel expenditures to the activity of traffic enforcement, allocating non-personnel expenditures to that activity through selection and use of an appropriate cost driver, and calculation of the revenue generated from traffic enforcement.

Capital Budgeting Approaches

Methods of Capital Budgeting

There are four types of capital budgeting techniques that are widely used in the corporate world –

1. Net Present Value
2. Internal Rate of Return
3. Payback Period
4. Profitability Index

Apart from the Payback period method which is an additive method, rest of the methods are based on Discounted Cash Flow technique. Even though cash flow can be calculated based on the nature of the project, for the simplicity of the article we are assuming that all the expected cash flows are realized at the end of the year.

Discounted Cash Flow approaches provide a more objective basis for evaluating and selecting investment projects. They take into consideration both –

1. Timing of the expected cash flows – stockholders of Budgeting Somerville have higher preference for cash returns over 4-5 years rather than 10-15 years given the nature of the volatility in the industry.
2. Magnitude of both incoming and outgoing cash flows – Projects can be capital intensive, time intensive, or both. Budgeting Somerville shareholders have preference for diversified projects investment rather than prospective high income from a single capital intensive project.

Formula and Steps to Calculate Net Present Value (NPV) of City of Somerville:Using Activity-Based Budgeting to Improve Performance in the Somerville Traffic Unit

NPV = Net Cash In Flowt1 / (1+r)t1 + Net Cash In Flowt2 / (1+r)t2 + … Net Cash In Flowtn / (1+r)tn
Less Net Cash Out Flowt0 / (1+r)t0

Where t = time period, in this case year 1, year 2 and so on.
r = discount rate or return that could be earned using other safe proposition such as fixed deposit or treasury bond rate. Net Cash In Flow – What the firm will get each year.
Net Cash Out Flow – What the firm needs to invest initially in the project.

Step 1 – Understand the nature of the project and calculate cash flow for each year.
Step 2 – Discount those cash flow based on the discount rate.
Step 3 – Add all the discounted cash flow.
Step 4 – Selection of the project

Why Global Business Managers need to know Financial Tools such as Net Present Value (NPV)?

In our daily workplace we often come across people and colleagues who are just focused on their core competency and targets they have to deliver. For example marketing managers at Budgeting Somerville often design programs whose objective is to drive brand awareness and customer reach. But how that 30 point increase in brand awareness or 10 point increase in customer touch points will result into shareholders’ value is not specified.

To overcome such scenarios managers at Budgeting Somerville needs to not only know the financial aspect of project management but also needs to have tools to integrate them into part of the project development and monitoring plan.

Calculating Net Present Value (NPV) at 15%

After working through various assumptions we reached a conclusion that risk is far higher than 6%. In a reasonably stable industry with weak competition - 15% discount rate can be a good benchmark.

Years	Cash Flow	Net Cash Flow	Cumulative     Cash Flow	Discount Rate @ 15 %	Discounted Cash Flows
Year 0	(10021664)	-10021664	-	-
Year 1	3451335	-6570329	3451335	0.8696	3001161
Year 2	3980708	-2589621	7432043	0.7561	3009987
Year 3	3955698	1366077	11387741	0.6575	2600936
Year 4	3229233	4595310	14616974	0.5718	1846324
TOTAL					10458408

The Net NPV after 4 years is 436744

(10458408 - 10021664 )

Calculating Net Present Value (NPV) at 20%

If the risk component is high in the industry then we should go for a higher hurdle rate / discount rate of 20%.

Years	Cash Flow	Net Cash Flow	Cumulative     Cash Flow	Discount Rate @ 20 %	Discounted Cash Flows
Year 0	(10021664)	-10021664	-	-
Year 1	3451335	-6570329	3451335	0.8333	2876113
Year 2	3980708	-2589621	7432043	0.6944	2764381
Year 3	3955698	1366077	11387741	0.5787	2289177
Year 4	3229233	4595310	14616974	0.4823	1557308
TOTAL					9486978

The Net NPV after 4 years is -534686

At 20% discount rate the NPV is negative (9486978 - 10021664 ) so ideally we can't select the project if macro and micro factors don't allow financial managers of Budgeting Somerville to discount cash flow at lower discount rates such as 15%.

Acceptance Criteria of a Project based on NPV

Simplest Approach – If the investment project of Budgeting Somerville has a NPV value higher than Zero then finance managers at Budgeting Somerville can ACCEPT the project, otherwise they can reject the project. This means that project will deliver higher returns over the period of time than any alternate investment strategy.

In theory if the required rate of return or discount rate is chosen correctly by finance managers at Budgeting Somerville, then the stock price of the Budgeting Somerville should change by same amount of the NPV. In real world we know that share price also reflects various other factors that can be related to both macro and micro environment.

In the same vein – accepting the project with zero NPV should result in stagnant share price. Finance managers use discount rates as a measure of risk components in the project execution process.

Sensitivity Analysis

Project selection is often a far more complex decision than just choosing it based on the NPV number. Finance managers at Budgeting Somerville should conduct a sensitivity analysis to better understand not only the inherent risk of the projects but also how those risks can be either factored in or mitigated during the project execution. Sensitivity analysis helps in –

What will be a multi year spillover effect of various taxation regulations.

What are the uncertainties surrounding the project Initial Cash Outlay (ICO’s). ICO’s often have several different components such as land, machinery, building, and other equipment.

What can impact the cash flow of the project.

What are the key aspects of the projects that need to be monitored, refined, and retuned for continuous delivery of projected cash flows.

Understanding of risks involved in the project.

Some of the assumptions while using the Discounted Cash Flow Methods –

Projects are assumed to be Mutually Exclusive – This is seldom the came in modern day giant organizations where projects are often inter-related and rejecting a project solely based on NPV can result in sunk cost from a related project.

Independent projects have independent cash flows – As explained in the marketing project – though the project may look independent but in reality it is not as the brand awareness project can be closely associated with the spending on sales promotions and product specific advertising.
