Long-Term and Short-Term Debt. We maintain debt levels we consider appropriate after evaluating a number of factors, including cash flow expectations, cash requirements for ongoing operations, investment and financing plans (including acquisitions and share repurchase activities) and the overall cost of capital. Total debt was $35.4 billion as of June 30, 2014 and $31.5 billion as of June 30, 2013. Our total debt increased in 2014 mainly due to debt issuances and an increase in commercial paper outstanding, partially offset by bond maturities.
