As used in this Form 10-Q, the terms "Boise Cascade," "we," and "our" refer to Boise Cascade, L.L.C., and its consolidated subsidiaries prior to our conversion to a Delaware corporation and to Boise Cascade Company and its consolidated subsidiaries on or after such conversion. On February 4, 2013, we converted to a Delaware corporation from a Delaware limited liability company by filing a certificate of conversion in Delaware. The common stock authorized and outstanding, par values, net income per share amounts, and other per-share disclosures for all periods presented have been adjusted to reflect the impact of this conversion. We are one of the largest producers of engineered wood products (EWP) and plywood in North America and a leading U.S. wholesale distributor of building products. &lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;On February 11, 2013, we issued &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;13,529,412&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; shares of common stock in our initial public offering.

style="line-height:120%;text-indent:48px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;We are a building products company
headquartered in Boise, Idaho. Our operations began on October&amp;#160;29, 2004 (inception), when we acquired the forest products and paper assets of
OfficeMax (the Forest Products Acquisition). As used in these consolidated financial statements, the terms "Boise Cascade," "we," and "our" refer to
Boise Cascade, L.L.C., and its consolidated subsidiaries prior to our conversion to a Delaware corporation and to Boise Cascade Company and its
consolidated subsidiaries on or after such conversion, as discussed in Note 16, Subsequent Events. Prior to the initial public offering of shares of
common stock of Boise Cascade Company, discussed in Note 13, Equity, Boise Cascade was 100% owned by Boise Cascade Holdings, L.L.C. (BC Holdings). We
are a leading U.S. wholesale distributor of building products and one of the largest producers of engineered wood products (EWP) and plywood in North
America.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div

reportable segments: (1) Building Materials Distribution, which is a wholesale distributor of building materials, (2) Wood Products, which manufactures
and sells EWP, plywood, studs, particleboard, and ponderosa pine lumber, and (3) Corporate and Other, which includes corporate support staff services,
related assets and liabilities, and foreign exchange gains and losses. For more information, see Note 14, Segment Information.&lt;/font&gt;&lt;/div&gt;&lt;div

indent:48px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;In connection with the sale of our Paper and Packaging &amp;amp; Newsprint
assets in 2008, we received &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;$1,277.2 million&lt;/font&gt;&lt;font style="font-family:inherit;font-
size:10pt;"&gt; of cash consideration, a &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;$41 million&lt;/font&gt;&lt;font style="font-family:inherit;font-
size:10pt;"&gt; paid-in-kind promissory note receivable, and &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;$285.2 million&lt;/font&gt;&lt;font
style="font-family:inherit;font-size:10pt;"&gt; of net stock consideration. Immediately following the sale, we distributed the securities received in the
transaction to BC Holdings, as the securities were not subject to the collateral liens of the bank credit facility of the company then in effect.
However, the cash and securities received in the transaction were subject to the covenants of the company's subordinated note indenture in effect at the
time of the distribution and the guaranty provided by BC Holdings. As a result of receiving stock in Boise Inc., BC Holdings had a significant indirect
financial interest in the results of the sold businesses. The equity interest BC Holdings owned in Boise Inc. and the related-party transactions we had
with Boise Inc. after the sale represented a significant continuing involvement. In 2008, BC Holdings sold the paid-in-kind promissory note receivable
for &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;$52.7 million&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; after selling
expenses and transferred the net proceeds to us. In 2009 and 2010, BC Holdings sold &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;18.8
million&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; and &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;18.3 million&lt;/font&gt;&lt;font
style="font-family:inherit;font-size:10pt;"&gt; shares of Boise Inc. and transferred the net proceeds of &lt;/font&gt;&lt;font style="font-family:inherit;font-
size:10pt;"&gt;$83.2 million&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; and &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;$86.1
million&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; to us. The cash received as a reinvestment in us by BC Holdings was reflected in our
Consolidated Statements of Cash Flows. We used the cash received from BC Holdings in 2008, 2009, and 2010 to repay senior debt and for capital spending
in accordance with the asset sale covenant of our subordinated note indenture. The &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;18.3
million&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; shares sold in 2010 represented BC Holdings' remaining investment in Boise Inc. Because
of the disposition, Boise Inc. is no longer a related party. The related-party activity with Boise Inc. included in the Consolidated Financial
Statements includes only those sales and costs and expenses transacted prior to March 2010, when Boise Inc. was a related party. As a result, beginning
in March 2010, transactions with Louisiana Timber Procurement Company, L.L.C. (LTP) (discussed in Note&amp;#160;4, Transactions With Related Parties)
represent the only remaining significant related-party activity recorded in our consolidated financial statements.&lt;/font&gt;&lt;/div&gt;&lt;/div&gt;</NonNumbericText><FootnoteIndexer /><CurrencyCode /><CurrencySymbol /><IsIndependantCurrency>false</IsIndependantCurrency><ShowCurrencySymbol>false</ShowCurrencySymbol><DisplayDateInUSFormat>false</DisplayDateInUSFormat></Cell></Cells><ElementDataType>nonnum:textBlockItemType</ElementDataType><SimpleDataType>na</SimpleDataType><ElementDefenition>The entire disclosure for organization, consolidation and basis of presentation of financial statements disclosure.</ElementDefenition><ElementReferences>Reference 1: http://www.xbrl.org/2003/role/presentationRef
