The present value of the remaining obligation under these agreements is $5.5 million at December 31, 2019, and is recorded as a long term liability. We do not maintain any off-balance sheet debt or other similar financing arrangements nor have we formed any special purpose entities for the purpose of maintaining off-balance sheet debt.
