So what: Arcos Dorados, the largest McDonald's franchisee, said it completed repayment on R$613.9 million 10.25% Brazilian real denominated senior notes maturing on July 13, 2016.

The company had secured a four-year loan in March and used the proceeds to pay off the 10.25% last month. Arcos Dorados management has spent the year shoring up its financial position by selling off restaurants to franchisees and refinancing its debt.

Now what: While shares of Arcos Dorados have more than doubled since February, the stock has been a big loser, falling more than 70% since its 2011 IPO. A recession across much of South America, including Brazil and Venezuela, and a weak Brazilian real has pressured the company over its history, but the stock has been gaining new life under a new CEO.

Though those countries still have not reached an inflection point in any economic turnaround, management's moves have helped restore confidence in the stock and its future, and analysts are expecting the company to turn a small profit this year. Considering the underlying popularity of McDonald's, Arcos Dorados should eventually find its way back to meaningful profitability.
