From the story here:
Mass-mailing checks to strangers might seem like risky business, but Mariner Finance occupies a fertile niche in the U.S. economy. The company enables some of the nation’s wealthiest investors and investment funds to make money offering high-interest loans to cash-strapped Americans.
Mariner Finance is owned and managed by a $11.2 billion private equity fund controlled by Warburg Pincus, a storied New York firm. The president of Warburg Pincus is Timothy F. Geithner, who, as treasury secretary in the Obama administration, condemned predatory lenders. The firm’s co-chief executives, Charles R. Kaye and Joseph P. Landy, are established figures in New York’s financial world. The minimum investment in the fund is $20 million.
Dozens of other investment firms bought Mariner bonds last year, allowing the company to raise an additional $550 million. That allowed the lender to make more loans to people like Huggins [at 33 percent].
