is downgraded below a specified threshold, the new bank is required to provide credit support for its obligation.
Fees of $5 million were incurred in connection with this replacement.
On November 29, 2011, Standard and Poor's reduced its credit rating of senior unsecured long-term debt of Lloyds TSB Bank Plc, which issued letters of credit that support $1.2 billion of the Timber Notes, below the specified threshold.
The letters of credit were successfully replaced by another qualifying institution.
Fees of $4 million were incurred in connection with this replacement.
On January 23, 2012, Standard and Poor's reduced its credit rating of senior unsecured long-term debt of Société Générale SA, which issued letters of credit that support $666 million of the Timber Notes, below the specified threshold.
The letters of credit were successfully replaced by another qualifying institution.
Fees of $5 million were incurred in connection with this replacement.
On June 21, 2012, Moody's Investor Services reduced its credit rating of senior unsecured long-term debt of BNP Paribas, which issued letters of credit that support $707 million of Timber Notes, below the specified threshold.
On December 19, 2012, the Company and the third-party managing member agreed to a continuing replacement waiver for these letters of credit, terminable upon 30 days notice.
Activity between the Company and the Entities was as follows:
## Table 0 ##
(a) The net expense related to the Company’s interest in the Entities is included in Interest expense, net in the accompanying consolidated statement of operations, as International Paper has and intends to effect its legal right to offset as discussed above.
(b) The cash receipts are equity distributions from the Entities to International Paper.
(c) The semi-annual payments are related to interest on the associated debt obligations discussed above.
Based on an analysis of the Entities discussed above under guidance that considers the potential magnitude of the variability in the structures and which party has a controlling financial interest, International Paper determined that it is not the primary beneficiary of the Entities, and therefore, should not consolidate its investments in these entities.
It was also determined that the source of variability in the structure is the value of the Timber Notes, the assets most significantly impacting the structure’s economic performance.
The credit quality of the Timber Notes is supported by irrevocable letters of credit obtained by third-party buyers which are 100% cash collateralized.
International Paper analyzed which party has control over the economic performance of each entity, and concluded International Paper does not have control over significant decisions surrounding the Timber Notes and letters of credit and therefore is not the primary beneficiary.
The Company’s maximum exposure to loss equals the value of the Timber Notes; however, an analysis performed by the Company concluded the likelihood of this exposure is remote.
International Paper also held variable interests in two financing entities that were used to monetize long-term notes received from the sale of forestlands in 2001 and 2002.  International Paper transferred notes (the Monetized Notes, with an original maturity of 10 years from inception) and cash of approximately $1.0 billion to these entities in exchange for preferred interests, and accounted for the transfers as a sale of the notes with no associated gain or loss.
In the same period, the entities acquired approximately $1.0 billion of International Paper debt obligations for cash.
International Paper has no obligation to make any further capital contributions to these entities and did not provide any financial support that was not previously contractually required during the years ended December 31, 2013, 2012 or 2011.
The 2001 Monetized Notes of $499 million matured on March 16, 2011.
Following their maturity, International Paper purchased the Class A preferred interest in the 2001 financing entities from an external third-party for $21 million.
As a result of the purchase, effective March 16, 2011, International Paper owned 100% of the 2001 financing entities.
Based on an analysis performed by the Company after the purchase, under guidance that considers the potential magnitude of the variability in the structure and which party has a controlling financial interest, International Paper determined that it was the primary beneficiary of the 2001 financing entities and thus consolidated the entities effective March 16, 2011.
Effective April 30, 2011, International Paper liquidated its interest in the 2001 financing entities.
Activity between the Company and the 2001 financing entities during 2011 was immaterial.

(1) Beginning in 2010, tangible ratios are computed net of deferred taxes associated with intangible assets.
Prior periods have been revised to conform with current presentation.
(2) Only one year of projected future taxable income may be applied in calculating deferred tax assets for regulatory capital purposes.
CRITICAL ACCOUNTING POLICIES AND ESTIMATES In preparing financial information, management is required to make significant estimates and assumptions that affect the reported amounts of assets, liabilities, income and expenses for the periods shown.
The accounting principles followed by Regions and the methods of applying these principles conform with accounting principles generally accepted in the U. S.  and general banking practices.
Estimates and assumptions most significant to Regions are related primarily to the allowance for credit losses, fair value measurements, intangible assets (goodwill and other identifiable intangible assets), mortgage servicing rights and income taxes, and are summarized in the following discussion and in the notes to the consolidated financial statements.
Allowance for Credit Losses The allowance for credit losses (“allowance”) consists of the allowance for loan losses and the reserve for unfunded credit commitments.
These two components reflect management’s judgment of probable credit losses
additional liquidity in the market, pricing rationale largely returned, enabling Regions to increase its low-cost customer deposits and reduce its total deposit costs from 1.35 percent in 2009 to 0.78 percent in 2010.
Table 14—Deposits
## Table 2 ##
Regions elected to exit the Federal Deposit Insurance Corporation’s (“FDIC”) Transaction Account Guarantee (“TAG”) program on July 1, 2010.
The TAG program was a component of the Temporary Liquidity Guarantee Program, whereby the FDIC guarantees all funds held at participating institutions beyond the $250,000 deposit insurance limit in qualifying transaction accounts.
Regions’ decision to exit the program did not have a significant impact on liquidity.
When the Dodd-Frank Act was enacted in July 2010, it permanently increased the FDIC coverage limit to $250,000.
Also as a result of the Dodd-Frank Act, effective as of December 31, 2010, unlimited coverage for non-interest bearing demand transaction accounts will be provided until January 1, 2013.
Within customer deposits, non-interest-bearing deposits increased $2.5 billion to $25.7 billion, driven by an increase in non-interest bearing deposits from commercial and small businesses and a mix shift from interestbearing transaction accounts which decreased 15 percent to $13.4 billion.
Non-interest-bearing deposits accounted for approximately 27 percent of total deposits at year-end 2010 as compared to 24 percent at year-end 2009.
Savings balances increased $595 million to $4.7 billion, generally reflecting growing savings trends, spurred by economic uncertainty.
Domestic money market products, which exclude foreign money market accounts, are one of Regions’ most significant funding sources.
These balances increased 18 percent in 2010 to $27.4 billion or 29 percent of total deposits, compared to 24 percent of total deposits in 2009 and 21 percent of total deposits in 2008.
Money market accounts steadily increased throughout 2010.
Also, foreign money market accounts decreased $197 million, or 26 percent, to $569 million in 2010.
Included in customer time deposits are certificates of deposit and individual retirement accounts.
The balance of customer time deposits decreased 28 percent in 2010 to $22.8 billion compared to $31.5 billion in 2009.
The decrease was primarily due to maturities with minimal reinvestment by customers as a result of a decline in rates offered on these products.
Customer time deposits accounted for 24 percent of total deposits in 2010 compared to 32 percent in 2009.
Consistent with 2009, total treasury deposits, which are used mainly for overnight funding purposes, remained at low levels in 2010 as the Company continued to utilize customer-based funding and other sources.
The Company’s choice of overnight funding sources is dependent on the Company’s particular funding needs and the relative attractiveness of each source.
