Notes to Consolidated Financial Statements (Continued)
(1) Significant accounting policies and practices (Continued)
(e) Receivables, loans and finance receivables (Continued)
recognized based on the terms of the new loan. Loans that have gone through foreclosure are charged off when the
collateral is sold. Loans not in foreclosure are evaluated for charge off based on individual circumstances concerning
the future collectability of the loan and the condition of the collateral securing the loan.
(f) Derivatives
We carry derivative contracts at fair value. Such balances reflect reductions permitted under master netting agreements
with counterparties. The changes in fair value of derivative contracts that do not qualify as hedging instruments for
financial reporting purposes are recorded in earnings.
Cash collateral received from or paid to counterparties to secure derivative contract assets or liabilities is included in
other liabilities or other assets. Securities received from counterparties as collateral are not recorded as assets and
securities delivered to counterparties as collateral continue to be reflected as assets in our Consolidated Balance Sheets.
(g) Fair value measurements
As defined under GAAP, fair value is the price that would be received to sell an asset or paid to transfer a liability
between market participants in the principal market or in the most advantageous market when no principal market
exists. Adjustments to transaction prices or quoted market prices may be required in illiquid or disorderly markets in
order to estimate fair value. Alternative valuation techniques may be appropriate under the circumstances to determine
the value that would be received to sell an asset or paid to transfer a liability in an orderly transaction. Market
participants are assumed to be independent, knowledgeable, able and willing to transact an exchange and not acting
under duress. Nonperformance or credit risk is considered in determining the fair value of liabilities. Considerable
judgment may be required in interpreting market data used to develop the estimates of fair value. Accordingly,
estimates of fair value presented herein are not necessarily indicative of the amounts that could be realized in a current
or future market exchange.
(h) Inventories
Inventories consist of manufactured goods and goods acquired for resale. Manufactured inventory costs include raw
materials, direct and indirect labor and factory overhead. Inventories are stated at the lower of cost or market. As of
December 31, 2013, approximately 42% of our consolidated inventory cost was determined using the last-in-first-out
(“LIFO”) method, 32% using the first-in-first-out (“FIFO”) method, with the remainder using the specific identification
method or average cost methods. With respect to inventories carried at LIFO cost, the aggregate difference in value
between LIFO cost and cost determined under the FIFO method was $796 million and $793 million as of December 31,
2013 and 2012, respectively.
(i) Property, plant and equipment
Additions to property, plant and equipment are recorded at cost and consist of major additions, improvements and
betterments. With respect to constructed assets, all construction related material, direct labor and contract services as
well as certain indirect costs are capitalized. Indirect costs include interest over the construction period. With respect to
constructed assets of certain of our regulated utility and energy subsidiaries that are subject to authoritative guidance
for regulated operations, capitalized costs also include an equity allowance for funds used during construction, which
represents the equity funds necessary to finance the construction of the domestic regulated facilities. Also see
Note 1(p).
Normal repairs and maintenance and other costs that do not improve the property, extend the useful life or otherwise do
not meet capitalization criteria are charged to expense as incurred. Rail grinding costs related to our railroad properties
are expensed as incurred.
