Notes to Consolidated Financial Statements Ball Corporation and Subsidiaries 13.
Debt and Interest Costs (continued) Long-term debt obligations outstanding at December 31, 2007, have maturities of $127.1 million, $160 million, $388.4 million, $625.1 million and $550.3 million for the years ending December 31, 2008 through 2012, respectively, and $456.1 million thereafter.
Ball provides letters of credit in the ordinary course of business to secure liabilities recorded in connection with industrial development revenue bonds and certain self-insurance arrangements.
Letters of credit outstanding at December 31, 2007 and 2006, were $41 million and $52.4 million, respectively.
The notes payable and senior credit facilities are guaranteed on a full, unconditional and joint and several basis by certain of the company’s domestic wholly owned subsidiaries.
Certain foreign denominated tranches of the senior credit facilities are similarly guaranteed by certain of the company’s wholly owned foreign subsidiaries.
Note 22 contains further details as well as condensed, consolidating financial information for the company, segregating the guarantor subsidiaries and non-guarantor subsidiaries.
The company was not in default of any loan agreement at December 31, 2007, and has met all debt payment obligations.
The U. S.  note agreements, bank credit agreement and industrial development revenue bond agreements contain certain restrictions relating to dividend payments, share repurchases, investments, financial ratios, guarantees and the incurrence of additional indebtedness.2006 On March 27, 2006, Ball expanded its senior secured credit facilities with the addition of a $500 million Term D Loan facility due in installments through October 2011.
Also on March 27, 2006, Ball issued at a price of 99.799 percent $450 million of 6.625% senior notes (effective yield to maturity of 6.65 percent) due in March 2018.
The proceeds from these financings were used to refinance existing U. S.  Can debt with Ball Corporation debt at lower interest rates, acquire certain North American plastic container net assets from Alcan and reduce seasonal working capital debt.
(See Note 3 for further details of the acquisitions. )2005 On October 13, 2005, Ball refinanced its senior secured credit facilities to extend debt maturities at lower interest rate spreads and provide the company with additional borrowing capacity for future growth.
During the third and fourth quarters of 2005, Ball redeemed its 7.75% senior notes due in August 2006.
The refinancing and senior note redemptions resulted in a debt refinancing charge of $19.3 million ($12.3 million after tax) for the related call premium and unamortized debt issuance costs.
A summary of total interest cost paid and accrued follows:
## Table 1 ##
(a) Includes $6.6 million paid in 2005 in connection with the redemption of the company’s senior and senior subordinated notes.
PSB.
PSB revenue increased by 18% to $693.4 million for fiscal year 2009, compared to $588.4 million for fiscal year 2008.
Our NVIDIA professional workstation product sales increased due to an overall unit increase of approximately 15% in shipments of boards and chips as compared to fiscal year 2008, due to strong demand and our transition from previous generations of NVIDIA Quadro professional workstation products to GeForce 8-based and GeForce 9-based products.
Sales of NVIDIA Quadro CX for Adobe’s CS4 software, which we launched in the third quarter of fiscal year 2009, also contributed towards the increase in sales in fiscal year 2009.
MCP Business.
MCP business revenue decreased by 8% to $655.6 million for fiscal year 2009, compared to $710.4 million for fiscal year 2008.
This decrease was due to a decline of approximately 32% in sales of our AMD-based platform products resulting from increased competition in AMD-based products, offset by an increase of approximately 120% in sales of our Intel-based platform products.
The increase in Intel-based product sales was driven by sales of our GeForce 9400M mGPU, which we launched in October 2008 along with Apple Inc. , or Apple, for their new lineup of Mac notebooks, and our new GeForce 9400 and 9300 mGPUs for Intel desktop PCs.
CPB.
CPB revenue decreased by 46% to $136.3 million for fiscal year 2009, compared to $251.1 million for fiscal year 2008.
The decline in CPB revenue is primarily driven by a combination of a decrease in revenue from our cell phone products and a decrease in revenue from Sony Computer Entertainment, or SCE.
The decrease in revenue from our cell phone products resulted from our shift from marketing and developing legacy products to achieving design wins and marketing our newer Tegra products.
The decrease in our revenue from SCE resulted from a decline in license revenue and a decline in royalty revenue that was caused by a lower number of units shipped as well as by a step-down in the per unit royalty rate during the year due to achievement of a unit-based milestone in our agreement with SCE.
Concentration of Revenue We generated 84%, 87% and 89% of our total revenue for fiscal years 2010, 2009 and 2008, respectively, from sales to customers outside the United States and other Americas.
Revenue by geographic region is allocated to individual countries based on the location to which the products are initially billed even if the foreign contract equipment manufacturers, or CEMs’, add-in board and motherboard manufacturers’ revenue is attributable to end customers in a different location.
Revenue from significant customers, those representing 10% or more of total revenue for the respective dates, is summarized as follows:
## Table 2 ##
Gross Profit and Gross Margin Gross profit consists of total revenue, net of allowances, less cost of revenue.
Cost of revenue consists primarily of the cost of semiconductors purchased from subcontractors, including wafer fabrication, assembly, testing and packaging, manufacturing support costs, including labor and overhead associated with such purchases, final test yield fallout, inventory and warranty provisions and shipping costs.
Cost of revenue also includes development costs for license, service arrangements and stockbased compensation related to personnel associated with manufacturing.
