FORTIS INC. $36 (www.fortisinc.com) has agreed to buy Chevron Corp.’s 93.8% stake in the Aitken Creek underground gas storage facility in northeastern B.C.; BP Canada owns the remaining 6.2%. Fortis will pay $266 million U.S. when it completes the purchase in early 2016. To put that in context, the company earned $145 million (Canadian), or $0.52 a share, in the third quarter of 2015. Fortis currently leases one-third of Aitken Creek’s capacity, so the purchase should lower its costs. Buy.
