The best in class

Back in 1991, the development of project finance models was our first line of business. Today, our modelling methodology has grown to be widely acknowledged as one of the most transparent and established examples of best practice modelling in the industry.

The members of our highly skilled and respected team have strong analytical backgrounds gained in engineering, mathematics and physical sciences which enable them to develop complex financial models which can be understood by a range of stakeholders within a transaction.

One of our key strengths is that the same team carries out all the modelling and auditing work which ensures the rigour of an audit is combined with the experience of developing a model.

Rolling out template models is not our style; we understand that every client and every transaction is different and we tailor our delivery team according to the particular needs of the assignment.

Flexible models to suit your needs

African prison project

Recent changes to the project agreement governing the project’s operations required the owners to seek a flexible financial model to allow the running of a range of scenarios relevant to the changing nature of the project. A key requirement was to ensure a broad range of stakeholders could understand and interpret the model.

UK transport project

With the project still in construction and falling behind its completion deadline, a range of penalties were looking ominous. With this in mind, Operis was engaged by the shareholders to construct a financial model enabling combination of project monitoring tools and forecasting scenarios in order to accurately predict the financial eventualities.

Canadian power portfolio

A North American power company required a financial model to analyse and illustrate the financing implications for a number of their power assets. Operis was engaged to build this model, which accepted historic costs and revenues and forecasted the performance of each separate project for the benefit of the investors and funders.

Steps to complete your model

Define the outputs

Once we know about the project, the first step in developing a financial model is understanding what the key outputs of the model are, whether it be a combination of financial statements, ratios, indicators or graphs.

Review the inputs

With the outputs are established, it is important to understand where the input data will come from. This may comprise data exports from accounting systems, trial balances data or management account schedules drawn up for other purposes.

Establish how the items evolve

For each item in the model, discussion will ensue as to how the information should evolve over time. Whilst some items should continue forward using the same treatment and assumptions, other data may move at a higher or lower rate than the current base case projections.

Iterative model development

Once the outputs are defined, the inputs known, and the forecast approach established for each item, it is then just a case of the analyst joining the dots and developing the model through successive iterations. We expect to have the first draft of the model to you in around 2 weeks from commencing.
