ACCC releases draft new merger guidelines for consultation



The much anticipated draft new merger guidelines were released by the Australian Competition and Consumer Commission (ACCC) for public comment on Friday.

The draft guidelines outline the principles used by the ACCC to analyse the competitive effects of mergers and acquisitions.

A substantial rewrite of the guidelines has occurred with many significant changes in content and approach. The draft guidelines are a clear improvement over the old 1999 merger guidelines and the ACCC has obviously taken great care in their formulation.


Key points

The most important changes are as follows:

The so-called ‘safe harbours’ based on CR4 ‘concentration ratio’ and 40 per cent market share have been replaced by voluntary notification thresholds

Under the new thresholds, the ACCC encourages pre-merger voluntary notification if any of the following criteria are likely to apply:

The merged firm would operate in at least one market that is concentrated

A market is considered ’concentrated’ if its Herfindahl-Hirschman Index (HHI) exceeds 2000. The HHI is a measure of market concentration routinely used for merger analysis in jurisdictions such as the United States and is calculated as the sum of the squares of the market shares of all firms in the relevant market.

The merger parties are ‘number 1’ and ‘number 2’

A substantial number of customers consider the products of the merger parties to be particularly close substitutes such that the merger parties represent their first and second choices.

The target firm is a ‘maverick’

The target firm has shown a recent rapid increase in market share, has driven innovation or has tended to charge lower prices than its competitors in one or more markets in which the merged firm would operate.

The merged firm would be a clear market leader

The merged firm would have a significantly higher market share than any of its rivals in one or more markets.

The firm or industry is under ACCC scrutiny

The ACCC has indicated to a firm or industry that notification of proposed mergers in that industry would be advisable, given past history in that industry or the level of acquisitive activity.

The ACCC says that it will rarely investigate a merger if it falls outside these notification thresholds.

However, these thresholds are set at a low level. In practice, we would expect that many proposed acquisitions will cross these thresholds but raise no competition concerns.

Greater emphasis is placed by the ACCC on gathering supporting evidence

Supporting information and documents are likely to be subject to a higher level of ACCC scrutiny, consistent with recent ACCC practice.

For example:

Greater emphasis is placed by the ACCC on identifying and analysing the long term competitive effects of mergers

The ACCC has identified its key theories of competitive harm, categorised by type of merger. These theories explore such issues as the scope for post-merger strategic behaviour by one or more firms in an industry, including, for example:

Merger analysis under the new guidelines will be more tailored to the specific features and context of the particular merger and its long term consequences for industry structure and behaviour.

Consistent with recent practice, the guidelines also identify that the ACCC will determine the materiality of any lessening of competition by identifying the extent to which it confers an increase in market power on the merged firm that is significant and sustainable. The ACCC may consider this to occur if the merged firm is able profitably to increase prices by around 5–10 per cent for a period of 1–2 years.

Likely consequences and implications

We do not expect that the draft guidelines will result in any dramatic shift in approach by the ACCC towards the consideration of mergers.

The 1999 merger guidelines were overdue for a review. The ACCC has taken the opportunity to update the guidelines to ensure that they are consistent with recent legislative changes and case law and international regulatory best practice.

The draft guidelines also articulate the ACCC’s recent practice and current thinking, much of which is already well known. By way of example, the so-called ‘import test’ has been toughened so that several additional conditions must now be met for imports to defeat a lessening of competition. These additional conditions test the extent to which imports would realistically constrain any market power of the merged firm and had previously been implicit in the ACCC’s analysis.

However, the draft guidelines are likely to have the following implications:

Opportunity to influence content

Public submissions on the draft guidelines are due to the ACCC by Friday 28 March 2008.

However, the draft guidelines have been carefully crafted and are clearly the result of substantial background thought. We therefore believe the ACCC may be reluctant to make substantive revisions flowing from the public consultation process.
