Future Financings

•

Remain flexible and opportunistic as to timing and approach

–

Manage CapEx

with close regard to stock price and cost of capital

•

Amount and type of financing will depend on nexus between

need to balance capital structure matched with capital market

conditions

•

Next long-term financing likely to be a first mortgage bond

offering

•

At current stock price and present capital plan, no need to issue

equity in the near term
