Revenue Recognition

For certain client contracts where we recognize revenues over time, we recognize the amount that we have the right to invoice, which corresponds directly to the value provided to the client of our performance to date.

We do not disclose the amount of unsatisfied performance obligations for client contracts with an original expected length of one year or less and those client contracts for which we recognize revenues at the amount to which we have the right to invoice for services performed. We have other contracts with revenues expected to be recognized subsequent to March 31, 2019 related to remaining performance obligations, which are not material.

We record accounts receivable when our right to consideration becomes unconditional. Contract assets primarily relate to our rights to consideration for services provided that they are conditional on satisfaction of future performance obligations. We record contract liabilities (deferred revenue) when payments are made or due prior to the related performance obligations being satisfied. The current portion of our contract liabilities is included in accrued liabilities in our Consolidated Balance Sheets. We do not have any material contract assets or long-term contract liabilities.

Our deferred revenue was $39.2 at March 31, 2019 and $42.8 at December 31, 2018. The decrease is due to $23.6 of revenues recognized related to amounts that were included in the December 31, 2018 balance, partially offset by payments or amounts due in advance of satisfying our performance obligations in the first three months of 2019.

In the following table, revenue is disaggregated by service types for each of our reportable segments. See Note 2 to the consolidated financial statements in our 2018 Annual Report on Form10-K for descriptions of revenue service types:
