Off-Balance Sheet Arrangements We have operating leases for certain property and equipment under various noncancelable agreements, the most significant of which are rail car leases and barge tow charters for the transportation of fertilizer, and terminal and office leases.
The rail car leases currently have minimum terms ranging from one to ten years and the barge charter commitments currently have terms ranging from one to four years.
We also have terminal and warehouse storage agreements at several of our distribution locations, some of which contain minimum throughput requirements.
The storage agreements contain minimum terms ranging from one to three years and commonly contain automatic annual renewal provisions thereafter unless canceled by either party.
In 2006, we entered into a ten-year operating lease agreement for a new corporate headquarters located in Deerfield, Illinois.
The Deerfield corporate office lease agreement includes leasehold incentives, rent holidays and scheduled rent increases that are expensed on a straight-line basis.
Our other operating lease agreements do not contain significant contingent rents, leasehold incentives, rent holidays, scheduled rent increases, concessions or unusual provisions.
See Note 26 to our consolidated financial statements for additional information concerning leases.
We do not have any other off-balance sheet arrangements that have or are reasonably likely to have a material current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources.
Critical Accounting Policies and Estimates Our discussion and analysis of our financial condition, results of operations, liquidity and capital resources is based upon our consolidated financial statements, which have been prepared in accordance with United States generally accepted accounting principles, or GAAP.
GAAP requires that we make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosure of contingent assets and liabilities.
On an ongoing basis, we evaluate our estimates.
We base our estimates on historical experience, technological assessment, opinions of appropriate outside experts, and the most recent information available to us.
Actual results may differ from these estimates.
Changes in estimates that may have a material impact on our results are discussed in the context of the underlying financial statements to which they relate.
The following discussion presents information about our most critical accounting policies and estimates.
Revenue Recognition We recognize revenue when title and risk of loss are transferred to the customer, which can be at the plant gate, a distribution facility, a supplier location or a customer destination.
In some cases, application of this policy requires that we make certain assumptions or estimates regarding a component of revenue, discounts and allowances, rebates, or creditworthiness of some of our customers.
We base our estimates on historical experience, and the most recent information available to us, which can change as market conditions change.

Concentrations of Credit Risk (Equity Securities).
The Company is not exposed to any concentrations of credit risk in its equity securities holdings of any single issuer greater than 10% of the Company’s stockholders’ equity at December 31, 2009 and 2008.
Maturities of Fixed Maturity Securities.
The amortized cost and estimated fair value of fixed maturity securities, by contractual maturity date (excluding scheduled sinking funds), are as follows:
## Table 2 ##
Actual maturities may differ from contractual maturities due to the exercise of call or prepayment options.
Fixed maturity securities not due at a single maturity date have been included in the above table in the year of final contractual maturity.
RMBS, CMBS and ABS are shown separately in the table, as they are not due at a single maturity.
Evaluating Available-for-Sale Securities for Other-Than-Temporary Impairment As described more fully in Note 1, the Company performs a regular evaluation, on a security-by-security basis, of its available-for-sale securities holdings in accordance with its impairment policy in order to evaluate whether such investments are other-than-temporarily impaired.
As described more fully in Note 1, effective April 1, 2009, the Company adopted new OTTI guidance that amends the methodology for determining for fixed maturity securities whether an OTTI exists, and for certain fixed maturity securities, changes how the amount of the OTTI loss that is charged to earnings is determined.
There was no change in the OTTI methodology for equity securities.
With respect to fixed maturity securities, the Company considers, amongst other impairment criteria, whether it has the intent to sell a particular impaired fixed maturity security.
The Company’s intent to sell a particular impaired fixed maturity security considers broad portfolio management objectives such as asset/liability duration management, issuer and industry segment exposures, interest rate views and the overall total return focus.
In following these portfolio management objectives, changes in facts and circumstances that were present in past reporting periods may trigger a decision to sell securities that were held in prior reporting periods.
Decisions to sell are based on current conditions or the Company’s need to shift the portfolio to maintain its portfolio management objectives including liquidity needs or duration targets on asset/liability managed portfolios.
The Company attempts to anticipate these types of changes and if a sale decision has been made on an impaired security, the security will be deemed other-than-temporarily impaired in the period that the sale decision was made and an OTTI loss will be recorded in earnings.
In certain circumstances, the Company may determine that it does not intend to sell a particular security but that it is more likely than not that it will be required to sell that security before recovery of the decline in estimated fair value below amortized cost.
In such instances, the fixed maturity security will be deemed other-than-temporarily impaired in the period during which it was determined more likely than not that the security will be required to be sold and an OTTI loss will be recorded in earnings.
If the Company does not have the intent to sell (i. e. , has not made the decision to sell) and it does not believe that it is more likely than not that it will be required to sell the security before recovery of its amortized cost, an impairment assessment is made, as described in Note 1.
Prior to April 1, 2009, the Company’s assessment of OTTI for fixed maturity securities was performed in the same manner as described below for equity securities.
MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (Continued) 63 The following table presents average U. S.  and non-U.
S.  short-duration advances for the years ended December 31:
## Table 3 ##
Although average short-duration advances for the year ended December 31, 2013 increased compared to the year ended December 31, 2012, such average advances remained low relative to historical levels, mainly the result of clients continuing to hold higher levels of liquidity.
Average other interest-earning assets increased to $11.16 billion for the year ended December 31, 2013 from $7.38 billion for the year ended December 31, 2012.
The increased levels were primarily the result of higher levels of cash collateral provided in connection with our participation in principal securities finance transactions.
Aggregate average interest-bearing deposits increased to $109.25 billion for the year ended December 31, 2013 from $98.39 billion for the year ended December 31, 2012.
This increase was mainly due to higher levels of non-U.
S.  transaction accounts associated with the growth of new and existing business in assets under custody and administration.
Future transaction account levels will be influenced by the underlying asset servicing business, as well as market conditions, including the general levels of U. S.  and non-U.
S.  interest rates.
Average other short-term borrowings declined to $3.79 billion for the year ended December 31, 2013 from $4.68 billion for the year ended December 31, 2012, as higher levels of client deposits provided additional liquidity.
Average long-term debt increased to $8.42 billion for the year ended December 31, 2013 from $7.01 billion for the year ended December 31, 2012.
The increase primarily reflected the issuance of $1.0 billion of extendible notes by State Street Bank in December 2012, the issuance of $1.5 billion of senior and subordinated debt in May 2013, and the issuance of $1.0 billion of senior debt in November 2013.
This increase was partly offset by maturities of $1.75 billion of senior debt in the second quarter of 2012.
Average other interest-bearing liabilities increased to $6.46 billion for the year ended December 31, 2013 from $5.90 billion for the year ended December 31, 2012, primarily the result of higher levels of cash collateral received from clients in connection with our participation in principal securities finance transactions.
Several factors could affect future levels of our net interest revenue and margin, including the mix of client liabilities; actions of various central banks; changes in U. S.  and non-U.
S.  interest rates; changes in the various yield curves around the world; revised or proposed regulatory capital or liquidity standards, or interpretations of those standards; the amount of discount accretion generated by the former conduit securities that remain in our investment securities portfolio; and the yields earned on securities purchased compared to the yields earned on securities sold or matured.
Based on market conditions and other factors, we continue to reinvest the majority of the proceeds from paydowns and maturities of investment securities in highly-rated securities, such as U. S.  Treasury and agency securities, federal agency mortgage-backed securities and U. S.  and non-U.
S.  mortgage- and asset-backed securities.
The pace at which we continue to reinvest and the types of investment securities purchased will depend on the impact of market conditions and other factors over time.
We expect these factors and the levels of global interest rates to dictate what effect our reinvestment program will have on future levels of our net interest revenue and net interest margin.
