Margin valuation adjustment (MVA)
Margin valuation adjustment allows for the funding costs of the initial margin posted for a derivatives trade. This can apply to cleared trades, which require initial margin, and non-cleared trades, where initial margin requirements are being phased in over time. The central counterparty basis is also a form of MVA.
