All common stocks will be delisted at end of business on May 7.

Walter Energy said its decision to delist was primarily based on the low trading volume of its shares on the TSX over a sustained period.

The company said it could no longer justify the financial and administrative costs associated with maintaining a dual listing.

Following its delisting from the TSX, Walter Energy's shares will continue to trade on the New York Stock Exchange under the symbol WLT.

Canadian shareholders will be able to continue to trade their shares of Walter Energy on the NYSE.

Walter Energy employs approximately 3100 employees, with operations in the United States, Canada and United Kingdom.
