companies and additions to property and equipment. These impacts were partially offset by a $2.77 billion increase in net cash from combined investment purchases, sales, and maturities. 

 

Fiscal year 2006 compared to fiscal year 2005 

 

Cash flow from operations decreased $2.20 billion primarily due to increased payments to fund a $987 million increase in Xbox 360 inventory and product costs and increased payments to employees resulting from a 16% growth in headcount. These factors were partially offset by increased cash receipts from customers driven by our 11% revenue growth and a $1.74 billion increase in unearned revenue. Cash used in financing decreased $20.52 billion driven by a $32.57 billion reduction in cash dividend payments. This impact was partially offset by an $11.15 billion increase in common stock repurchases. Net cash from investing decreased $7.02 billion driven primarily by an $8.93 billion decrease in cash from combined purchase, sales, and maturities of investments and a $766 million increase in additions to property and equipment. These factors were partially offset by $3.12 billion of net cash proceeds from our securities lending program. 

We have no material long-term debt. Stockholders’ equity at June 30, 2007, was $31.10 billion. We will continue to invest in sales, marketing, product support infrastructure, and existing and advanced areas of technology. Additions to property and equipment will continue, including new facilities, data centers, and computer systems for research and development, sales and marketing, support, and administrative staff. Commitments for constructing new buildings were $821 million on June 30, 2007. We have operating leases for most U.S. and international sales and support offices and certain equipment under which we incurred rental expense totaling $326 million, $276 million, and $299 million in fiscal year 2007, 2006, and 2005, respectively. We have not engaged in any related party transactions or arrangements with unconsolidated entities or other persons that are reasonably likely to materially affect liquidity or the availability of requirements for capital resources. In May 2007, we announced that we had entered into an agreement to purchase aQuantive, Inc. for approximately $6 billion in cash. We expect to complete this transaction in August 2007.
