consolidated debt; we recognize the fair value of the commitment on the settlement date as a component of debt in the cost basis of the debt issued.
We recognized losses on our mortgage commitments in the second quarter and first half of both 2011 and 2010 primarily due to losses on commitments to sell mortgage-related securities as a result of a decline in interest rates during the commitment period.
Trading Securities Gains (Losses), Net
The gains from our trading securities in the second quarter of 2011 were primarily driven by a decrease in interest rates. The gains from our trading securities in the first half of 2011 were primarily driven by the narrowing of credit spreads on commercial mortgage-backed securities (CMBS).
The gains from our trading securities in the second quarter and first half of 2010 were primarily driven by a decrease in interest rates and narrowing of credit spreads.
We refer to our provision for loan losses and the provision for guaranty losses collectively as our provision for credit losses. Credit-related expenses consist of our provision for credit losses and foreclosed property expense.
Provision for Credit Losses
Our total loss reserves provide for an estimate of credit losses incurred in our guaranty book of business as of each balance sheet date. We establish our loss reserves through the provision for credit losses for losses that we believe have been incurred and will eventually be reflected over time in our charge-offs. When we determine that a loan is uncollectible, typically upon foreclosure, we record a charge-off against our loss reserves. We record recoveries of previously charged-off amounts as a reduction to charge-offs, which results in an increase to our loss reserves.
Table 11 displays the components of our total loss reserves and our total fair value losses previously recognized on loans purchased out of MBS trusts reflected in our condensed consolidated balance sheets. Because these fair value losses lowered our recorded loan balances, we have fewer inherent losses in our guaranty book of business and consequently require lower total loss reserves. For these reasons, we consider these fair value losses as an effective reserve, apart from our total loss reserves, to the extent that we expect to realize credit losses on the acquired loans in the future. We estimate that approximately two-thirds of this amount, as of June 30, 2011, represents credit losses we expect to realize in the future and approximately one-third will eventually be recovered, either through net interest income for loans that cure or through foreclosed property income for loans where the sale of the collateral exceeds our recorded investment in the loan. We exclude these fair value losses from our credit loss calculation as described in Credit Loss Performance Metrics.
