[1] Short-term restricted cash and cash equivalents are amounts expected to be released and categorized as unrestricted cash within twelve months of the balance sheet date.

[2] Long-term inventory includes modules that are contractually required to be segregated for use as replacement modules for specific project assets. Given that these project assets are long-term, the Company classifies the inventory as long-term regardless of the expected timing of such module replacements.
