Thanks, Alan. Good morning, everyone. Thanks for joining us today. The resilience of our overall business served us well over the last few months, and virtually all our operations have recovered from the depths of the economic shutdown, with many of them approaching activity levels similar to last year. With that in mind, we've refocused our efforts on growth and are now seeing an increase in private market transaction activity across all our regions. Our global scale and local presence in the regions where we operate positions us to evaluate opportunities as they arise. And because our investment approach provides us with flexibility to invest in different forms, we can choose to acquire control positions in businesses, acquire debt or equity securities or provide financing to companies to support their growth or capitalization.
Recently, we've been looking at a few high-quality businesses, which have been impacted by near-term volatility and reduced levels of demand. We're also reviewing carve-outs from conglomerates and underperforming public companies that could give rise to attractive value opportunities.
During the quarter, we continued to grow our existing businesses. Buying more businesses we already own or acquiring add-on businesses is an efficient and low-risk way for us to add value and grow BBU. In October, we entered into an agreement to acquire the 43% publicly held shares in Genworth Canada, which was recently rebranded as Sagen. Sagen is Canada's largest private mortgage insurer to the Canadian banks, and we acquired a controlling interest in this company late last year. At the time, we would have liked to acquire the entire business, but the seller required speed and certainty of execution, which didn't allow us to tender for the publicly held shares. So our offer for the remaining publicly held shares for book value is at the same value which we paid to acquire the control block last year and really a natural extension of our initial investment in this company.
Canadian banks and the federal government have provided support to homeowners through mortgage deferrals and other wage subsidization programs. As these programs come to an end, both defaults and loss ratios will inevitably increase. Sagen currently operates with enough capital headroom to absorb these losses. But in the event that loss ratios are elevated for a sustained period of time, we are well positioned alongside our institutional partners to provide this business with temporary support.
We believe we can run this business more efficiently as a private company by optimizing the capital structure and improving returns earned on its investment portfolio. BBU expects to fund approximately $460 million of the transaction, which will increase its ownership to 40%. The transaction is expected to close in the first half of 2021, subject to regulatory and shareholder approval.
We're also pursuing add-on opportunities that will enhance the capabilities and reach of our portfolio companies. For example, at our fuel distributor, Greenergy, we signed an agreement during the quarter to purchase a portfolio of 35 retail fuel sites in Ireland. This acquisition increases both the scale and vertical integration of Greenergy's operations in that country.
We're seeing these types of add-on opportunities surfacing across all regions. And in India and Brazil, our businesses are benefiting from our sponsorship and access to capital in this environment. I'd like to provide you with a little bit of context on the importance of BRK's recent acquisition of a 35-year concession to provide water services to the city of Maceió in northeastern Brazil. Maceió is a city of 1.5 million people located in an area where BRK already has extensive operations. In addition to providing water services, BRK plans to build over 3,000 kilometers of pipeline, install over 400,000 new customer connections that will extend access to sewage collection to over 90% of residents compared to less than 30% of residents today. BRK is one of a handful of water service companies in Brazil with the operational capabilities to manage and execute these types of large-scale capital projects.
Sanitation represents a major infrastructure requirement in Brazil. The government estimates that a capital investment of $60 billion is required in the sector over the next 10 to 15 years. This was the first auction following the regulatory change in Brazil supporting increased private investment in the sanitation sector, and we expect additional attractive opportunities to come to market in the near future, which should provide BRK with additional growth opportunity.
Getting back to the overall business environment, while we anticipate that uncertainty in business conditions will continue for some time, we've been very pleased with the overall resilience of our business. We're confident in the potential for BBU to continue to generate growth of intrinsic value per unit, driven by our capital recycling initiatives and the value creation plans in place at each of our businesses.
With that, I'm going to hand it over to Denis.
