Independent Expert Reports and the methodologies used

BDO is at the top of the leader board, particularly for mining, resources, oil, and gas companies, when it comes to the number of independent expert reports (‘IER’) prepared to support transactions in the mergers and acquisitions space in Australia. This position gives us visibility on the challenges that can be faced before they occur.

To assist future clients and their advisers in preparing for an IER, BDO Perth holds an annual independent experts breakfast presenting to listed companies and legal and corporate advisors. The breakfast presentations cover what we saw in the IER space in the previous year, and what you need to know for the coming year. One of the questions often asked is on choice of methodologies.

The methodologies used – rule of thumb

A question often asked is what methodologies we’ll be using, in particular, will we be using Discounted Cash Flow. Although we need to observe some clear regulatory requirements on these discussions so that we can protect your transaction from a compromise of our independence, we can provide a rule of thumb.

The valuation approaches chosen will depend on stage of development of your assets and will determine who needs to value what.

Who values what

BDO (an Independent Expert) has the specialist knowledge and skills to value the companies involved in the transaction. To value a company and its securities, the company’s assets generally also need to be valued. Sometimes BDO will engage an Independent Technical Specialist to value a company’s assets. BDO will then rely on their valuation to value the entities that are part of the transaction to arrive at an opinion on whether the transaction is fair and reasonable to non-associated shareholders.

For mining and resources companies the valuation methodologies depend on the stage of development of the mineral asset. They will be valued by a mining valuation Specialist who will be guided by the VALMIN Code 2015[1] in choosing the most appropriate valuation approach (market, income, or cost).

Some clients ask if they can choose the Independent Technical Specialist, because they know the company’s assets well, have done work for the company before, or can engage them for a low fee.

It is the Independent Expert’s responsibility to choose and instruct a Technical Specialist so that we can ensure they are independent, remain independent during the course of the work, and have the qualifications and experience relevant to the asset to be able to arrive upon a reliable opinion.

A mining valuation Specialist must fully understand and have the experience with the disclosure obligations under VALMIN 2015, and JORC 2012. If not, what seems low cost up front may end up costing in time and possibly reputation if the report is unlikely to meet the standard of VALMIN and JORC disclosure that the regulators require.

The Independent Expert values the corporate entity or entities using the asset values provided by the Technical Specialist and incorporating them into a chosen methodology. The approach is chosen by the Independent Expert and is dependent on the transaction type (takeover, related party, item 7 s611) and the requirements of the corporate regulator under ASIC Regulatory Guide 111 Content of Expert Reports.

Generally at least two valuation methodologies will be chosen by each expert. One approach is used as the primary, and the second as a cross-check. Differences in outcome are presented as a range and explained.

For example, a mining valuation Specialist will typically use at least two methodologies for each group of assets at similar stages of development (exploration, pre-development, development and production). The Independent Expert will then incorporate the Technical Specialist’s conclusion on value in at least one valuation approach. 

The methodologies chosen will also depend upon the amount of data available, and its reliability.

Use of DCF

Questions often arise from mining and resources companies on when a DCF can be used as a methodology.

For mining and resources companies this is best understood by referring to (link) ASIC Info Sheet 214 Mining and Resources – Forward looking statements. A Rule of Thumb however, is that we generally use a DCF for those projects that have a declared Ore Reserve as the work on these areas is likely to be sufficiently advanced to provide the greatest level of confidence that the underlying inputs, or assumptions are soundly based.

A Technical Specialist is engaged to review and assess the reasonableness of the technical inputs and assumptions within the company’s base cash flow model. For mining companies this is the resources, reserves, mining and processing physicals, production costs, operating costs, and capital expenditure used by the company in its base cash flow model.

As the Independent Expert, we provide the economic inputs for the model based on our host of research databases as well as our in-house economic and industry knowledge. These economic inputs include, but are not limited to, the discount rate, forecast pricing, forecast exchange rates and forecast inflation. The Independent Expert will also interrogate the model to ensure it is calculating correctly and will build in suitable sensitivities.

Using DCF when results are imminent

The challenge arises when a company is continuing to work on the project and an announcement on a Pre-Feasibility, Feasibility, or study upgrade is imminent. At the same time the company is in the midst of a transaction that requires an independent expert’s report.

Material results that are not sufficiently advanced or reliable to announce to the market, are generally not sufficiently reliable for the Independent Expert to use and publish in its report.

The Independent Expert is always very careful not to publish any confidential information in its report. Sometimes, a methodology other than DCF must be used unless the expert has the confidence that the results of a study will be finalised and disclosed before the IER is published.  

In these circumstances it is important to be aware that after the announcement is made, and prior to the finalisation of the IER, the expert will need to check the previously provided draft information against the final information that is announced.

It is also important to be aware that any material information disclosed after the publication of an IER and before approval of the transaction or close of the offer may require a review of the IER and issue of a supplementary report by the Independent Expert. This is because the newly released information may be material to the content of the IER and the Independent Expert’s conclusions.
