No further interest expense for Shurgard Europe will be reflected in our financial statements after March 31, 2008. (b) EBITDA represents earnings prior to interest, taxes, depreciation, amortization, gains on sale of real estate assets and the impact of the application of EITF Topic D-42. This supplemental disclosure of EBITDA is included because we believe that the coverage ratios computed on a pre-depreciation basis are a meaningful measure of our liquidity and financial analysts and other members of the investment community consider coverage ratios for real estate companies on a pre-depreciation basis. EBITDA should not be used as an alternative to net income, cash flow from operations, or our ratio of Earnings to Fixed Charges in evaluating our liquidity or operating results. Exhibit 12
