When Wells Fargo purchased Wachovia Bank in October 2008, global financial markets were in turmoil. Nevertheless, Wells Fargo clearly expected conditions to eventually improve, and for Wachovia to generate positive cash flows far into the future. Suppose that analysts at Wells Fargo project that their acquisition of Wachovia will generate the following stream of cash flows:

Year 1: $0.50 billion

Year 2: $1.00 billion

Year 3: $1.25 billion

Year 4: $1.50 billion

In year 5 and beyond, analysts believe that cash flows will continue to grow at a constant rate of 2.5% per year. Suppose that Wells Fargo discounted the cash flows of this investment at 11%. What is the terminal value of this investment at the end of year 4?
