ended December 31, 2015 and 2014, respectively.
The increase in cash provided by accounts payable-inventory financing was primarily due to a new vendor added to our previously existing inventory financing agreement.
For a description of the inventory financing transactions impacting each period, see Note 6 (Inventory Financing Agreements) to the accompanying Consolidated Financial Statements.
For a description of the debt transactions impacting each period, see Note 8 (Long-Term Debt) to the accompanying Consolidated Financial Statements.
Net cash used in financing activities decreased $56.3 million in 2014 compared to 2013.
The decrease was primarily driven by several debt refinancing transactions during each period and our July 2013 IPO, which generated net proceeds of $424.7 million after deducting underwriting discounts, expenses and transaction costs.
The net impact of our debt transactions resulted in cash outflows of $145.9 million and $518.3 million during 2014 and 2013, respectively, as cash was used in each period to reduce our total long-term debt.
For a description of the debt transactions impacting each period, see Note 8 (Long-Term Debt) to the accompanying Consolidated Financial Statements.
