Our debt balances, including related interest expense, increased in each of the years presented primarily due to the funding of a portion of our capital spending program using borrowings under bank credit agreements and the issuance of short- and long-term notes. For information regarding our debt balances, see Note 8 of the Notes to Consolidated Financial Statements included under Part II, Item 8 of this annual report.
Our equity balances, along with the number of common units outstanding, increased in each of the years presented due to the issuance of units in connection with business combinations and the sale of units under our at-the-market program, distribution reinvestment plan and employee unit purchase plan. Net proceeds generated from the sale of common units were primarily used to fund a portion of our capital spending program.
