Our operating leases expire at various dates through 2037 and are primarily for office space, cars, servers, and office equipment.

Our headquarters are located at 121 Seaport Boulevard, Boston, Massachusetts. In February 2019, we subleased a portion of our headquarters through June 30, 2022. We will receive approximately $9.1 million in sublease income over the term of the sublease. In March 2022, we have extended the sublease through June 30, 2023, and we will receive additional sublease income over the term of the extension of approximately $2.9 million.

As of March 31, 2022, we had net liabilities of $1.7 million related to excess facilities (compared to $3.6 million at September 30, 2021), representing $0.3 million of right-of-use assets and $2.0 million of lease obligations, all of which is classified as short term. Variable costs related to these exited facilities are included in our restructuring accrual. All expenses and income associated with exited facilities are included in restructuring and other charges, net (refer to Note 3. Restructuring and Other Charges).

In determining the amount of right-of-use assets for restructured facilities, we are required to estimate such factors as future vacancy rates, the time required to sublet properties and sublease rates. Updates to these estimates may result in revisions to the value of right-of-use assets recorded. The amounts recorded are based on the net present value of estimated sublease income. As of March 31, 2022, the right-of-use assets for exited facilities reflects discounted committed sublease income of approximately $0.7 million.

In the three and six months ended March 31, 2022, we made payments of $0.6 million and $1.3 million, respectively, related to lease costs for exited facilities. In the three and six months ended March 31, 2021, we made payments of $2.5 million and $6.3 million, respectively.
