[1] Finance lease assets are recorded net of accumulated amortization of $0.4 million as of March 29, 2025, and December 28, 2024. During the first quarter of fiscal 2024, we executed an agreement to purchase our leased facility in Malaysia for MYR 41.8 million, with the expectation that the title would transfer during fiscal 2024. We treated this transaction as a lease modification, and changed the classification to a finance lease, reducing our operating lease assets and liabilities by $0.4 million and increasing our finance lease assets and current lease liabilities by $8.8 million and $7.9 million, respectively. Due to a seller-imposed delay during the third quarter of fiscal 2024, the purchase date was delayed until fiscal 2025, triggering a modification of the finance lease resulting in the asset increasing to $9.5 million. At December 28, 2024, the finance lease liability decreased to $8.4 million, as a result of fluctuations in foreign currency exchange rates. On December 30, 2024, we completed the purchase of our leased facility in Melaka, Malaysia.

[3] During the first quarter of 2025, we executed an agreement to lease facilities in San Diego, California. This location will become our new headquarters after our Poway office lease terminates at the end of 2025. The San Diego lease is expected to commence on January 1, 2026, upon when we will add the lease asset and liability to our balance sheet. The minimum lease payments for this lease are $2.5 million, $3.0 million, $2.6 million, $ 3.0 million and $23.8 million for 2026, 2027, 2028, 2029 and thereafter, respectively.
