DBRS Confirms Union Gas at “A” and R-1 (low)

DBRS has today confirmed the ratings of the Unsecured Debentures/Medium-Term Note Debentures, the Commercial Paper and the Cumulative Redeemable Preferred Shares of Union Gas Limited (Union or the Company) at “A,” R-1 (low) and Pfd-2, respectively, all with Stable trends. The confirmations reflect relatively stable earnings contributions from Union’s regulated businesses (i.e., gas distributions, regulated storage and gas transmission), which accounted for the majority of consolidated earnings, and Union’s reasonable credit profile.

Union’s financial performance continued to benefit from the continued expansion of higher-margin non-regulated natural gas storage facilities, offset by higher cost-cutting pressure in the regulated business (as a result of Union’s regulatory regime having changed from a cost-of-service (COS) system to an incentive regulation (IR) framework in 2008). However, DBRS is concerned about rising non-regulated business exposure, affecting Union’s overall business risk profile and increasing earnings volatility. Non-regulated earnings increased from 10% in 2008 to more than 20% in 2010 (DBRS estimate) and are expected to continue to rise over the medium term. DBRS views the Company’s current 64% debt level target as rather high, given its rising non-regulated business exposure. DBRS notes that the Company has filed a rate case for the 2013 rebasing, asking for a 40% deemed equity (currently 36%). If its request is granted, DBRS expects Union to manage its balance sheet in line with the new regulatory capital structure and maintain greater financial flexibility, commensurate with the current rating category.

The IR framework creates uncertainty in the regulated business that did not exist under the COS system. Earnings from the regulated distribution business are under cost-saving pressure with the IR framework. Union is required to continue to identify cost-saving opportunities to overcome the productivity factor of 1.82% to improve its earnings. In addition, the Company is required to continue to manage its capital program effectively within its regulatory limits during the IR period since any extra capital investment as a result of its aging infrastructure may not be recovered in a timely fashion, which could weaken its credit metrics.
