We typically do not receive consideration and amounts are not due from our customer prior to the completion of our performance obligation and as such contract liabilities as of March 31, 2019 and revenue recognized in the three months ended March 31, 2019 and 2018 resulting from contract liabilities was not significant. Contract assets and accrued expenses - transportation expense fluctuate from period to period primarily based upon shipments in-transit at period end.
