Difficult situations can pose difficult questions. The current COVID-19 pandemic has brought into sharp focus material adverse change clauses in deals. The context, the condition, and the carve-outs to it, all need to be examined in determining whether a MAC has been triggered.
In brief
|
The modern MAC has evolved from humble origins. A MAC was typically defined as an event that had a material adverse effect on the business or financial position of the target. In other words, a MAC was a MAC. General qualitative formulations like that can be found in the early Australian cases, such as in the litigation that emerged from the 1982 Woolworths’ takeover bid for Grace Bros. They can also be found in more recent North American cases, most notably the seminal 2001 case of IBP Inc v Tyson Foods Inc.
The cases demonstrate difficulties in enforcing general, qualitative MAC’s. Tyson Foods was not allowed to walk away from its planned merger with IBP despite IBP suffering a 64% drop in quarterly earnings. A durationallysignificant fall was needed, and not a “short-term blip”. Many others have also failed. The recent success in a Delaware Court of Fresenius Kabi AG in walking away from its proposed deal with Akorn Inc, required a perfect storm of a sustained and significant earnings drop alongside widespread and pervasive regulatory breaches.
The difficulties in enforcing general MAC’s led to deeper thinking around these important provisions. In the Australian context, MAC’s began to have quantitative triggers around specific drops in earnings or net assets, sometimes in conjunction with a qualitative trigger, and sometimes in lieu of a qualitative trigger.
From the target’s perspective, more sophisticated carve-outs to the MAC being triggered began to emerge as well, with the result that the modern Australian MAC is now a more detailed and heavily negotiated provision than earlier iterations of the concept.
The context of a claim for a breach of a MAC is critical. And in that sense, there are often different contexts at play. These include:
There will be many different contexts in relation to the deals for which the COVD-19 situation has relevance. Questions of public policy, buyer aims in a radically altered landscape, and regret, whether buyer, financier or shareholder, will all be in the mix.
The condition that must be triggered is at the core of any MAC. Here, interesting questions for COVID-19 will centre around whether the MAC is qualitative or quantitative.
For qualitative MAC’s, the durational significance of the current situation will be a key question. The answer to that question will depend upon the business and specifically how the industry it operates in has been affected. Will COVID-19 be a “short-term blip” or something of durational significance? When will we realistically know that to a standard sufficient to meet a MAC?
Quantitative MAC’s will provide a theoretically clearer baseline to test against. Even then, challenges may remain for buyers where the effect on earnings is across recurring years, given that predicting the medium term effects may be difficult.
MAC’s tend to have a lengthy list of carve-outs.
Relevantly to COVID-19, general changes in business conditions or markets are carved out from MAC’s, as are changes in law. MAC’s will usually have a force majeure style carve out as well, though (pre-COVID-19) MAC’s have tended to be more fearful of weather events than pestilence.
MAC’s can also carve out matters known to the buyer. This can raise interesting questions as well, depending on precisely when the deal was signed and what was known of COVID-19 at that time.
In response to more sophisticated carve-outs, buyers have often sought to introduce an exception to the carve-out – being that the carve out (such as altered business conditions) cannot have had a disproportionately adverse effect on the target. This is usually referable to a disproportionality as against other companies in the relevant industry, though formulations can vary.
There is little doubt that business conditions have been affected by COVID-19. Some of the changes in laws we have already seen have also been significant. But determining whether the carve outs will keep a deal on foot will depend on drawing all of that together alongside the company’s performance while also keeping a look out for any exceptions to the carve out that could make the analysis more difficult.
A final and important observation is that in matters where a MAC is in dispute, evidence is important. The attempts of bidders to exercise a MAC have often failed due to the bidder not putting on the right evidence. Thus in the US case of Frontier Oil Corp v Holly Corp, the Court found that the relevant litigation could have been “catastrophic”, but that the bidder did not lead credible evidence that this would have been the case.
Simply put, the work needs to be done to build the bridge between the MAC and the facts. As relates to COVID-19, and whether it relates to prosecuting a MAC or a target resisting a buyer attempting to utilise one, more is needed
