Most tax-inversions have involved large U.S. companies buying substantially smaller foreign companies, but Burger King and Tim Horton’s are fairly comparable in size. Burger King’s current market cap is $9.55 billion, while Tim Horton’s is valued at $8.35 billion. Moreover, Tim Horton’s actually generates more than three times Burger King’s revenue, and also has more profit.

A few quick issues to consider while this all plays out:

1. McDonald’s has got to be loving it. Just imagine all of the passive-aggressive patriotic advertising its marketing gurus would come up with.

2. What would Warren say? Burger King is majority owned by 3G Group, a Brazilian private equity firm that last year partnered with Warren Buffett to buy Heinz. Buffett has publicly lauded 3G, and said he’d like to work with them again. But he’s also said that U.S. companies are not unduly burdened by taxes, when asked about the inversion issue. Seems something may have to give here.

3. Will Canadians revolt? Tim Horton’s is to Canadians what Dunkin’ Donuts is to Bostonians — not just their morning jolt, but part of their identity. The company already spent many years owned by Wendy’s — and even was incorporated in Delaware for a short period — and it’s hard to imagine that there is much enthusiasm for yet another American chain taking control.

4. Tipping point. Most proposed tax inversions so far have been for healthcare-related companies that don’t have much consumer brand awareness. Burger King, however, is much different. Got to wonder if this could be the spark that lights some congressional action (now that Walgreens has abandoned its own attempt)…

• Speaking of tax inversions: Bloomberg’s Zachary Mider has a piece up this morning about how private equity firms regularly employ their own style of tax inversions, by creating foreign holding companies to house newly-purchased U.S. assets. Examples include Bain Capital’s Sensata Technologies – a Massachusetts company based in the Netherlands – and a note about how Dell considered “relocating” out of Texas when negotiating its own buyout (it choose to remain in Round Rock, in part due to its many U.S. government contracts). Got to wonder if any executive action on inversions (since Congress has lost the will to act on anything) would address such situations…

• Fantasyland: Today’s largest VC funding is for DraftKings, a real-money fantasy sports site that raised $41 million in Series C funding led by The Raine Group. Word is that the deal was done at a pre-money valuation just shy of $200 million, and that chief rival Fanduel is working on its own new (similarly-sized) funding round (think Los Angeles for the lead investor).

The real question for these sites isn’t user growth, but rather if that growth will cause regulators at the state and/or federal level to reexamine their legality. At issue is whether fantasy sports is a game of skill (legal to wager on via the web) or game of chance (not so much). DraftKings will argue that it’s a game of skill, by pointing to statistics showing how its best players are able to win consistently, by using statistical analysis. Of course, that’s something that some online poker companies also have tried (and failed) to argue. Also will be interesting to see if the NFL formally makes an argument on behalf of the sites, given how fantasy sports has driven increased interest in its league. Around half of DraftKings business is tied to NFL football, and the company today also announced that it will award four players $1 million during the upcoming season.

• Old-fashioned: Despite what you may read, not all information theft is done via the Internet. Over the weekend of July 19-20, someone broke into the Sand Hill Road offices of venture capital firm Kleiner Perkins, and made off with “several laptops” (two of which were password-protected devices from the firm’s finance department). The theft was revealed in a KP letter to New Hampshire officials, as it seems one of the laptops contained personal information of a New Hampshire resident.

• VC scoop: Mike Dauber is joining Amplify Partners as a partner, after having spent the past six years as a principal with Battery Ventures (where his deals included Duetto, RelateIQ and Splunk).

Silicon Valley-based Amplify was launched in late 2012 by former Battery partner Sunil Dhaliwal, who wanted a small firm that would focus exclusively on early-stage tech infrastructure opportunities. It raised nearly $50 million for its debut fund -- around half of which already has been committed -- and plans to raise its second fund next year. 

• Related: Worth noting that Amplify is the fourth active VC firm to be founded or co-founded by ex-Battery folk. The others are Spark Capital (Todd Dagres), Homebrew (Satya Patel) and Shasta Ventures (Ravi Mohan). If this was pro sports, you’d refer to this as a successful coaching tree…
