(1) Represents the amount of remaining capital at the midpoint of our guidance. We expect to satisfy our remaining capital through the sale of “core-like,” non-core, and land asset dispositions. The proceeds from these asset sales may vary depending on the impact of the sales on our net debt to adjusted EBITDA ratio. For example, the sale of non-income-producing land benefits leverage more than the sale of an income-producing property.

The key assumptions behind the sources and uses of capital in the table above are a favorable capital market environment and performance of our core operations in areas such as delivery of current and future development and redevelopment projects, leasing activity, and renewals.  Our expected sources and uses of capital are subject to a number of variables and uncertainties, including those discussed under the “Forward-looking statements” section under Part I and the “Risk Factors” section under Item 1A of our annual report on Form 10-K for the year ended December 31, 2013, and in subsequent quarterly reports on Form 10-Q.  We expect to update our forecast of sources and uses of capital on a quarterly basis.
