Undrawn Lines of Credit  

 

We have available $1.9 billion in undrawn lines of credit. As described in Note 8 of the Notes to the Consolidated Financial Statements, we have an undrawn $1.2 billion first-lien revolving credit facility, as part of our 2011 Credit Facilities. The revolving credit facility carries a variable interest rate and expires in April 2016.  

 

We also have an undrawn $450 million revolving credit facility included in the 2012 Pacific Facilities, as described in Note 8 of the Notes to the Consolidated Financial Statements. The 2012 Pacific Facilities are secured by our Pacific routes and slots. This revolving credit facility carries a variable interest rate and expires in October 2017. In addition, we have undrawn bank revolving credit facilities of $250 million.  

 

The credit facilities mentioned above have covenants, such as collateral coverage ratios. If we are not in compliance with these covenants, we may be required to repay amounts borrowed under the credit facilities and may not be able to draw on the revolving credit facilities.  

 

Other  

 

Our ability to obtain additional financing, if needed, on acceptable terms could be adversely affected by the fact that a significant portion of our assets are subject to liens.  

 

Investing and Financing  

 

Investing Activities  

 

We incurred capital expenditures of $2.6 billion in 2013 , $2.0 billion in 2012 and $1.3 billion in 2011 . Our capital expenditures were primarily for the purchase of aircraft and aircraft modifications that upgraded aircraft interiors and enhanced our product offering. Also during 2013, we purchased a 49% equity investment in Virgin Atlantic for $360 million .  

 

We have committed to future aircraft purchases that will require significant capital investment, and have obtained long-term financing commitments for a substantial portion of the purchase price of these aircraft. We expect that we will invest approximately $2.3 billion in 2014 primarily for aircraft and aircraft modifications. We expect that the 2014 investments will be funded through cash from operations and new financings.  

 

Financings  

 

At December 31, 2013 , total debt and capital leases, including current maturities, was $11.3 billion , a $1.4 billion reduction from 

December 31, 2012 and a $5.9 billion reduction from December 31, 2009. We have focused on reducing our total debt over the past few years as part of our strategy to strengthen our balance sheet. In addition, we have refinanced previous financing transactions, which we expect to reduce our total future interest expense.  

 

In May 2013, we announced a plan to return more than $1 billion to shareholders over the next three years. As part of this plan, our Board of Directors initiated a quarterly dividend program and declared a $0.06 per share dividend in both August 2013 and November 2013. These dividends were paid in September 2013 and November 2013 and each totaled $51 million . In addition, the Board of Directors authorized a $500 million share repurchase program, to be completed no later than June 30, 2016 . During 2013 , we repurchased and retired approximately
