[1] Cash paid for interest, net of capitalized interest, is the sum of other interest expensed, as defined above, and interest paid by our mortgage and finance subsidiaries adjusted for the change in accrued interest on notes payable, which is calculated as follows: Year Ended October 31, October 31, October 31, (In thousands) 2020 2019 2018 Other interest expensed $ 103,801 $ 90,056 $ 103,297 Interest paid by our mortgage and finance subsidiaries 2,165 2,536 2,478 (Increase) decrease in accrued interest (16,482) 16,515 6,241 Cash paid for interest, net of capitalized interest $ 89,484 $ 109,107 $ 112,016
[2] Other interest expensed includes interest that does not qualify for interest capitalization because our assets that qualify for interest capitalization (inventory under development) do not exceed our debt, which amounted to $61.9 million, $56.9 million and $76.2 million for the years ended October 31, 2020, 2019 and 2018, respectively. Other interest also includes interest on completed homes, land in planning and fully developed lots without homes under construction, which does not qualify for capitalization, and therefore, is expensed. This component of other interest was $41.9 million, $33.2 million and $27.1 million for the years ended October 31, 2020, 2019 and 2018, respectively.
