Federal Home Loan Mortgage Corporation (Freddie Mac)

Company Overview

Freddie Mac — the Federal Home Loan Mortgage Corporation — is the government-sponsored enterprise that supports the U.S. housing market by purchasing mortgage loans, packaging them into guaranteed mortgage-backed securities, and selling those securities to investors, earning fees and spreads while avoiding most interest-rate risk. For Wesco Financial, Freddie Mac was the single most profitable investment in its history: a $72 million purchase by its savings and loan subsidiary that grew, over roughly two decades of patient holding, into a position carried at $1.4 billion before its sale in 2000.

The Freddie Mac position sits at the intersection of every major Munger theme: regulatory arbitrage as an edge (the shares could initially be owned legally only by savings and loan associations), capital reallocation (thrift assets converted into a superior business), concentration (4% of the company, the legal maximum for one holder), and long-term compounding through inactivity. Munger documented the position meticulously across the Wesco annual letters, and the numbers tell the story so cleanly that they became one of his favorite examples of what happens when a sound franchise is bought with privileged access and then simply held.

The business model, as the 1988 letter described it to shareholders, was a hybrid: an enterprise run then by a federal agency but owned privately, largely by institutional investors, which supports housing by purchasing mortgage loans for immediate transmutation into guaranteed mortgage-backed securities that it promptly sells. The structure is worth pausing on, because it inverts everything that made the thrift business fragile. A savings and loan holds the mortgages it originates, funding thirty-year fixed assets with demand deposits and praying the yield curve behaves. Freddie Mac passed the mortgages through to security buyers, keeping the fee and the guarantee spread while exporting the duration risk. One business is a bet on interest rates with a housing market attached; the other is a toll on the American mortgage, collected regardless of which way rates move.

Investment Story

The privileged window.

As the 2000 Wesco letter put it with elegant economy, the main tag end from Wesco's savings and loan days was an investment in Freddie Mac common stock, "purchased by Mutual Savings for $72 million at a time when Freddie Mac shares could be lawfully owned only by a savings and loan association." The thrift charter that Munger otherwise considered a structural liability conferred one great privilege: exclusive access to shares of a far better business. Mutual Savings used the charter to walk through that window before it closed.

The 1988 position report.

The 1988 Wesco letter records the position's early shape:

"Mutual Savings increased its position in preferred stock of Federal Home Loan Mortgage Corporation (widely known as 'Freddie Mac') to 2,400,000 when-issued shares. This is 4% of the total shares outstanding, the legal limit for any one holder... Mutual Savings' average cost is $29.89 per share, compared to a price of $50.50 per share in trading on the New York Stock Exchange at the end of 1988. Thus, based on 1988 yearend trading prices, Mutual Savings had an unrealized pre-tax profit in Freddie Mac shares of about $49.5 million."

— Wesco Financial Annual Letter, 1988

The same letter explains why Munger considered the franchise superior to the business Wesco was exiting: Freddie Mac earns fees and spreads while avoiding most interest-rate-change risk — "a much better business than that carried on by most (or indeed most of the top 10% of) savings and loan associations, as demonstrated by Freddie Mac's remarkable percentage returns earned on equity capital in recent years." The analysis is the Mutual Savings diagnosis in positive form: the thrift borrows short and lends long and dies by the mismatch; Freddie Mac intermediates the same mortgages while shedding the duration risk that made the thrift model fragile.

Two decades of doing nothing.

Between the late-1980s accumulation and the 2000 sale, the letters record essentially no trading — only the growing value of the position and the deferred-tax accounting around it. The 1999 letter records that the 28,800,000 shares owned at yearend 1999 (the share count grown by splits from the original 2.4 million) had a market value of $1.4 billion. Against the $72 million cost, that is roughly a nineteen-fold increase before considering the dividends collected along the way — achieved without a single act of brilliance after the original purchase, only the discipline of not disturbing a compounding machine.

The epilogue.

Eight years after the sale, in the 2008 financial crisis, both Freddie Mac and Fannie Mae were placed into federal conservatorship, their common and preferred shareholders effectively wiped out. Munger never claimed to have foreseen that ending; the 2000 sale was a capital-allocation and valuation decision, not a prediction. But the epilogue completes the lesson of the Fannie Mae confession in an unexpected direction: the same sale that crystallized the enormous tax bill also removed Wesco from the register before the GSE model's hidden risks — the retained-portfolio leverage and political mission-creep that would eventually destroy both enterprises — came due. Being out early looks like luck only until you notice that Munger's entire method is engineered to be out early: sell the fully valued compounder, pay the tax, and let someone else own the last chapter.

The sale and the tax lesson.

In 2000 Wesco sold the position, producing the principal portion of $852.4 million of after-tax securities gains for that year — against $7.3 million realized in 1999. The sale also crystallized a massive tax bill, and Munger used it at the 2001 annual meeting to make the structural point he had repeated for years:

"What a terrible, inefficient thing it is to own real estate and securities in a Section C Corporation [like Wesco and Berkshire]. The enormous taxes we paid when we sold Freddie Mac last year is an example of this. If we were a partnership, you wouldn't have had to pay this."

— Wesco Financial Annual Meeting, 2001

The 2000 letter had already walked shareholders through the arithmetic of the deferred-tax "interest-free loan from the government" — $705 million at yearend 1999, reduced to $258 million by the sale — and warned that no shareholder should value the remaining loan as perpetual. At the 2002 meeting his summary of the whole affair was one sentence: "We held that stock for a great many years, and of course made a great deal of money."

The self-critique.

Munger's public post-mortem was not triumphalism but a confession of missed scale:

"We bought 4% of Freddie Mac [many years ago] yet none of Fannie Mae. How could the same mind have done that?! It wasn't very smart."

— Wesco Financial Annual Meeting, 2006

Fannie Mae was Freddie Mac's twin, available on the same logic at the same time, and Munger bought none of it. The 4% legal limit capped the Freddie position; nothing capped the Fannie position but his own failure to extend the analysis one company further. Even in his greatest investment, his final accounting was that he had left more on the table than most investors ever take off it.

Business Analysis

The Freddie Mac machine deserves to be understood piece by piece, because its elegance is the whole investment case. A savings and loan originates a mortgage and keeps it: thirty years of fixed-rate asset funded by deposits that can reprice or flee tomorrow. Freddie Mac bought that same mortgage, guaranteed it, packaged it into a security, and sold the security to investors — keeping a guarantee fee and a servicing spread while the interest-rate risk traveled onward with the security. The fee stream required almost no incremental capital, scaled with the entire American mortgage market rather than with one institution's deposit base, and recurred annually on a book of business that renewed itself as mortgages were refinanced. It was, in effect, a royalty on U.S. housing finance — the capital-light toll-booth economics that Munger prized at See's Candies, transplanted into a federally chartered franchise with an explicit public mission and an implicit public guarantee.

The implicit guarantee was the second engine. Because markets believed the federal government stood behind the GSEs, Freddie Mac borrowed at near-Treasury rates, and that funding advantage — unavailable to any purely private competitor — was itself a subsidy worth billions. Munger understood this perfectly well; it is why the franchise's returns on equity were, as the 1988 letter noted, remarkable. But the same federal connection contained the business's seed of destruction. Political pressure steadily widened the mission, and the retained portfolios the GSEs built to amplify earnings reintroduced — at vastly greater scale — precisely the leveraged duration mismatch that made ordinary thrifts fragile. When the housing market broke in 2008, the guarantee fees could not cover the credit losses, and conservatorship followed. The investor's lesson is asymmetric: the toll-booth half of the model was genuinely wonderful for two decades, and the leveraged-portfolio half was a latent claim on the franchise that arrived all at once. Munger's 2000 exit, taken for valuation and capital-allocation reasons rather than prophecy, removed Wesco before the latent half became manifest.

Investment Lessons

Regulation creates windows for those who read it carefully. The restriction of Freddie Mac ownership to thrifts was, for every other investor, an irrelevance; for Munger it was a monopoly on a buying opportunity. The edge required no forecasting ability — only the thrift charter he already owned, the statute, and the willingness to act while the window existed.

The better business next door is the best use of a bad business's capital. Mutual Savings' deposits and capital were earning thrift returns in a structurally flawed model; redirected into Freddie Mac shares, the same capital compounded at the rate of a superior franchise. The Freddie Mac position is the Mutual Savings extraction story told from the destination side.

Inactivity is a decision, and often the best one. The entire return came from two acts — buying in size when the window opened and holding through every intervening scare, recession, and rate cycle. Every year of the holding period offered plausible reasons to sell; the letters record that Munger noted them and held anyway.

Grade the misses alongside the hits. The Fannie Mae confession is Munger's epistemic hygiene applied to his own greatest success. The point of reviewing decisions is not to celebrate outcomes but to calibrate process — and by process measures, buying Freddie while ignoring Fannie was an error that no amount of profit converts into a success.

Deferred taxes are a float too. Munger's "interest-free loan from the government" framing turns a passive accounting entry into an active investment idea: unrealized appreciation, unsold, compounds pre-tax at the government's expense. The Freddie Mac position compounded for two decades on gross value, with the deferred-tax loan working silently alongside it — $705 million of government money, at zero interest, invested for Wesco shareholders by the simple act of not selling. The 2000 letter's warning that the loan was not perpetual is the other half of the idea: this float is real, it is valuable, and it vanishes the moment the gain is realized. Tax-aware inertia was not a byproduct of the strategy; it was part of its arithmetic.
