Since 1980, we have leased a corporate office, warehouse space, and additional parking located at 100, 130, and 140 Potrero Avenue, San Francisco, California from the various Dolby family trusts. The lease for this office expires on October 31, 2024, and provides approximately 70,000 square feet of space. The Dolby family trusts retain the right to sublease approximately 1,617 square feet of office space in the premises with prior notice to us, at a rental rate equal to the then current base rent per square foot paid by us plus $14 per square foot per year (reflecting estimated costs payable by us for the operation and maintenance of the premises, subject to an annual increase of 1.5% per year during each year of the sublease term).
In fiscal 2019, we ceased occupancy of the leased space at 100, 130, and 140 Potrero Avenue, and do not intend to re-occupy those locations. We remain responsible for operating expenses, taxes, and the condition, operation, repair, maintenance, security, and management of the premises. We have also agreed to indemnify and hold the Dolby family trusts, as landlord, harmless from and against certain liabilities, damages, claims, costs, penalties, and expenses arising from our conduct related to the premises. We also have a sublease with a subtenant for the remaining lease term at 100 Potrero Avenue, pursuant to which the subtenant is required to reimburse us with respect to the foregoing expenses and taxes with respect to the subleased premises and to indemnify and hold us harmless with respect to the subleased premises in the same manner described above.
