We have reached a 10-year agreement with adidas with respect to our global technical sponsorship and dual-branded licensing rights beginning with the 2015/16 season. The minimum guarantee payable by adidas is equal to £750 million, with an average annual installment of £75 million per year over the term of the agreement, subject to certain adjustments. See "Item 4. Information on the Company—Revenue Sectors—Commercial—Retail, Merchandising, Apparel & Product Licensing" for additional information regarding our agreement with adidas.
We also maintain a mixture of long-term debt and capacity under our revolving credit facility in order to ensure that we have sufficient funds available for short-term working capital requirements and for investment in the playing squad and other capital projects.
Our cost base is more evenly spread throughout the fiscal year than our cash inflows. Employee benefit expenses and fixed costs constitute the majority of our cash outflows and are generally paid throughout the 12 months of the fiscal year. Our working capital levels tend to be at their lowest in November, in advance of Premier League and UEFA broadcasting receipts in December
