MetLife, Inc.  Notes to the Consolidated Financial Statements — (Continued) The following table presents the components of accumulated other comprehensive income (loss), before income tax, related to cash flow hedges
## Table 1 ##
At December 31, 2011, $13 million of deferred net gains (losses) on derivatives in accumulated other comprehensive income (loss) was expected to be reclassified to earnings within the next 12 months.
The following table presents the effects of derivatives in cash flow hedging relationships on the consolidated statements of operations and the consolidated statements of equi
## Table 2 ##
All components of each derivative’s gain or loss were included in the assessment of hedge effectiveness.
Hedges of Net Investments in Foreign Operations The Company uses foreign exchange contracts, which may include foreign currency swaps, forwards and options, to hedge portions of its net investments in foreign operations against adverse movements in exchange rates.
The Company measures ineffectiveness on these contracts based upon the change in forward rates.
In addition, the Company may also use non-derivative financial instruments to hedge portions of its net investments in foreign operations against adverse movements in exchange rates.
The Company measures ineffectiveness on non-derivative financial instruments based upon the change in spot rates.
When net investments in foreign operations are sold or substantially liquidated, the amounts in accumulated other comprehensive income (loss) are reclassified
At December 31, 2013, the Company had approximately $35.3 million of U. S.  federal net operating loss carryforwards.
If not utilized, these carryforwards will expire in years 2023 through 2033.
The net operating loss carryforward increased between 2012 and 2013 primarily due to losses incurred by a U. S.  entity that is not a member of the Company’s consolidated tax group and therefore not available for offset against the taxable income of other members of the group.
In a recent acquisition, the consolidated group obtained federal net operating losses subject to an IRC Section 382 limitation; however, the Company expects to utilize the losses in their entirety prior to expiration.
The Company’s state net operating loss carryforwards are primarily related to Florida and New Jersey and will expire in years 2027 through 2030 if not utilized.
The New Jersey net operating loss was acquired as part of a recent acquisition.
The Company has smaller net operating losses in various other states.
Additionally, the Company has a foreign tax credit carryforward and a R&D tax credit carryforward.
As of December 31, 2013, the Company determined that a total valuation allowance of $5.9 million was necessary to reduce U. S.  deferred tax assets by $2.6 million and foreign deferred tax assets by $3.3 million, where it was more likely than not that some portion or all of such deferred tax assets will not be realized.
As of December 31, 2013, based on the Company’s estimates of future taxable income and any applicable tax-planning strategies within various tax jurisdictions, the Company believes that it is more likely than not that the remaining net deferred tax assets will be realized.
The Company recognizes in the consolidated financial statements only those tax positions determined to be “more likely than not” of being sustained upon examination based on the technical merits of the positions.
A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in thousands):
