Four times a year Berkshire Hathaway submits a filing with the SEC that discloses their holdings. Most Warren Buffett watchers dig in to see what current holdings have been added to along with any new stocks that have worked their way into Berkshire Hathaway’s holdings. I dig into the filings as well, but I’m looking for something a little different. I want to see what’s up with the short put trade that Berkshire Hathaway initiated back in the 2004 to 2008 time frame.
Some people may be unfamiliar with the trade I’m talking about, but may be aware that Warren Buffett called derivatives financial weapons of mass destruction in the Berkshire Hathaway 2002 annual report. Part of the commentary around this thought had to do with Long Term Capital Management and the focus was more on over the counter derivatives. However, by 2004 Berkshire Hathaway began initiating a pretty interesting over the counter equity index derivative trade. They sold puts on major market indexes.
Between 2004 and 2008 Berkshire Hathaway entered into what is referred to in annual reports as their equity put trade. The firm sold over the counter put options that will expire 15 to 20 years in the future. These positions are on four major equity indexes (S&P 500, EuroStoxx 50, FTSE 100, and Nikkei 225). Also, Buffett has pointed out that these are European style options that may not be exercised until expiration.
Not a ton of information has been forthcoming about these specific positions. Buffett has noted that they are at the money put options written on those four indexes. Also, the timing was not too great as the majority of the trades were done between 2004 and 2007. A small number of trades were added in 2008.
Below is a weekly chart of the S&P 500 with some highlights that coincide with the progression of events regarding these trades that appear after the chart.
1. In Warren Buffett’s 2007 Shareholder Letter it is disclosed that from 2004 to 2007 Berkshire Hathaway had sold put options on equity indexes that were struck at the money. These put options had brought in $4.5 billion in premiums, were European style options, and were due to expire between 2019 and 2027.
2. In the 2008 letter it was noted that the notional value of the put options totaled $37.1 billion and were written on the four major indices that were mentioned above. Buffett also states that they have added modestly to the equity put portfolio and have now received a total of $4.9 billion for selling these puts. Due to the drop in the global equity markets the valuation of these puts is a liability of $10 billion or a mark-to-market loss of $5.1 billion.
3. In the 2009 shareholder letter Buffett discloses that the terms of about 10% of the contracts have changed. The maturities were shortened and the strike prices lowered. It appears that they rolled the strike prices down and gave up some time. However it was also noted that in these modifications no money changed hands.
4. In the 2010 shareholder letter Buffett discusses that between 2004 and 2008 they received $4.8 billion in premiums for 47 equity index put contracts. It was also disclosed that at the instigation of their counterparty in these trades eight of the contracts were unwound. They had received $647 million for selling those puts and paid $425 million to get out of those obligations. This resulted in a profit of $222 million. This also left Berkshire with 39 short equity index put contracts on their books at year end.
5. At the end of 2011 the book value of the remaining put positions was a liability of $8.5 billion. This is determined using a Black Scholes model. Buffett notes that if the options had all come due at that time the payment would have been $6.2 billion.
6. At the end of 2012 the liability based on their open short put positions had dropped from $8.5 billion to $7.5 billion. Again this is based on a Black Scholes valuation.
7. In the most recent 10-Q it appears the liability is down to $5.35 billion which is again based on a Black Scholes valuation. This was based on the S&P 500 at 1690 (more than 100 points lower than today’s close). If global equity markets hold their current levels we may get a mention in the next shareholder letter that says the value of these positions is finally under the $4.2 billion that was received for them a few years back.
When everyone else is trying to find out if Warren Buffett has added to current positions on has added a new stock to his portfolio I’ll be digging through the 2013 letter to for any mention of the short put trades.
