security.
In both cases, the Corporation or a subsidiary may be required to settle the obligation for cash or other securities prior to the contractual maturity date.
These borrowings are reflected in the table as maturing at their contractual maturity date.
During 2014, the Corporation had total long-term debt maturities and purchases of $53.7 billion consisting of $33.9 billion for Bank of America Corporation, $8.9 billion for Bank of America, N. A.  and $10.9 billion of other debt.
During 2013, the Corporation had total long-term debt maturities and purchases of $65.6 billion consisting of $39.3 billion for Bank of America Corporation, $16.0 billion for Bank of America, N. A.  and $10.3 billion of other debt.
In 2013, in a combination of tender offers, calls and open-market transactions, the Corporation purchased senior and subordinated long-term debt with a carrying value of $9.2 billion and recorded net losses of $59 million in connection with these transactions.

Trust Preferred and Hybrid Securities Trust preferred securities (Trust Securities) are primarily issued by trust companies (the Trusts) that are not consolidated.
These Trust Securities are mandatorily redeemable preferred security obligations of the Trusts.
The sole assets of the Trusts generally are junior subordinated deferrable interest notes of the Corporation or its subsidiaries (the Notes).
The Trusts generally are 100 percent-owned finance subsidiaries of the Corporation.
Obligations associated with the Notes are included in the longterm debt table on page 208.
Certain of the Trust Securities were issued at a discount and may be redeemed prior to maturity at the option of the Corporation.
The Trusts generally have invested the proceeds of such Trust Securities in the Notes.
Each issue of the Notes has an interest rate equal to the corresponding Trust Securities distribution rate.
The Corporation has the right to defer payment of interest on the Notes at any time or from time to time for a period not exceeding five years provided that no extension period may extend beyond the stated maturity of the relevant Notes.
During any such extension period, distributions on the Trust Securities will also be deferred and the Corporation’s ability to pay dividends on its common and preferred stock will be restricted.
The Trust Securities generally are subject to mandatory redemption upon repayment of the related Notes at their stated maturity dates or their earlier redemption at a redemption price equal to their liquidation amount plus accrued distributions to the date fixed for redemption and the premium, if any, paid by the Corporation upon concurrent repayment of the related Notes.
Periodic cash payments and payments upon liquidation or redemption with respect to Trust Securities are guaranteed by the Corporation or its subsidiaries to the extent of funds held by the Trusts (the Preferred Securities Guarantee).
The Preferred Securities Guarantee, when taken together with the Corporation’s other obligations including its obligations under the Notes, generally will constitute a full and unconditional guarantee, on a subordinated basis, by the Corporation of payments due on the Trust Securities.
In 2013, the Corporation entered into various agreements with certain Trust Securities holders pursuant to which the Corporation paid $933 million in cash in exchange for $934 million aggregate liquidation amount of previously issued Trust Securities.
Upon the exchange, the Corporation immediately surrendered the Trust Securities to the unconsolidated Trusts for cancellation, resulting in the cancellation of an equal amount of junior subordinated notes that had a carrying value of $934 million, resulting in an insignificant gain.
Under customer usage agreements, the Company installs certain equipment (for example, a ThinPrep Processor or a ThinPrep Imaging System) at customer sites and customers commit to purchasing minimum quantities of disposable products at a stated price (generally including a usage fee for the equipment) over a defined contract term, which is typically between three and five years.
Revenue is recognized over the term of the customer usage agreement as disposable products are delivered.
The Company also rents certain equipment to customers.
Revenues from rental agreements are recorded over the term of the rental agreements.
Accounts Receivable and Reserves The Company records reserves for doubtful accounts based upon a specific review of all outstanding invoices, known collection issues and historical experience.
The Company regularly evaluates the collectability of its trade accounts receivables and performs ongoing credit evaluations of its customers and adjusts credit limits based upon payment history and its assessment of the customer’s current credit worthiness.
These estimates are based on specific facts and circumstances of particular orders, analysis of credit memo data and other known factors.
Accounts receivable reserve activity for fiscal years 2011, 2010 and 2009 is as follows:
## Table 1 ##
Cost of Service and Other Revenues Cost of service and other revenues primarily represents payroll and related costs associated with the Company’s professional services’ employees, consultants, infrastructure costs and overhead allocations, including depreciation and rent and materials consumed in providing the service.
Stock-Based Compensation The Company accounts for share-based payments in accordance with ASC 718, Stock Compensation.
As such, all share-based payments to employees, including grants of stock options and restricted stock units, are recognized in the consolidated statement of operations based on their fair values as the date of grant.
Net Income (Loss) Per Share Basic net income (loss) per share is computed by dividing net income (loss) by the weighted average number of common shares outstanding.
Diluted net income (loss) per share is computed by dividing net income (loss) by the weighted average number of common shares and potential common shares from outstanding stock options, restricted stock units and convertible debt determined by applying the treasury stock method.
In accordance with ASC 718, the assumed proceeds under the treasury stock method include the average unrecognized compensation expense of in-the-money stock options and restricted stock units.
The Company applies the provisions of ASC 260, Earnings Per Share, Subsection 10-45-44, to determine the diluted weighted average shares outstanding as it relates to its Convertible Notes, and due to the type of debt instrument issued, the Company applies the treasury stock method and not the ifconverted method.
The dilutive impact of the Company’s Convertible Notes is based on the difference between the Company’s current period average stock price and the conversion price of the Convertible Notes, provided there is a premium.
Pursuant to this accounting standard, there is no dilution from the accreted principal of the Convertible Notes.
In the first quarter of 2010, we expect higher containerboard and box prices from announced price increases, but most of the earnings benefit will not be realized until the second quarter when the price increase has been passed through to box customers.
We expect mill downtime and higher operating costs from our annual maintenance outage at Counce and our Valdosta mill outage for work related to our energy optimization project.
Much higher recycled fiber costs, higher energy costs associated with colder weather, a higher effective tax rate and higher timing-related benefit costs are also expected in the first quarter.
Considering all these items, we estimate our first quarter earnings will be lower than our fourth quarter earnings of $16 million, which excludes net income of $44 million from alternative fuel mixture tax credits and a $1 million after tax charge from asset disposals related to the energy optimization projects.
Results of Operations Year Ended December 31, 2009 Compared to Year Ended December 31, 2008 The historical results of operations of PCA for the years ended December 31, 2009 and 2008 are set forth below:
## Table 2 ##
Net Sales Net sales decreased by $212.9 million, or 9.0%, for the year ended December 31, 2009 from the year ended December 31, 2008.
Net sales decreased primarily due to the impact of lower sales volume ($145.5 million) and decreased sales prices of corrugated products and containerboard ($67.4 million).
Total corrugated products volume sold decreased 4.6% to 28.9 billion square feet in 2009 compared to 30.3 billion square feet in 2008.
On a comparable shipment-per-workday basis, corrugated products sales volume decreased 3.8% in 2009 from 2008.
Shipments-per-workday is calculated by dividing our total corrugated products volume during the year by the number of workdays within the year.
The larger percentage decrease, on a total shipments basis, was due to the fact that 2009 had two fewer workdays (250 days), those days not falling on a weekend or holiday, than 2008 (252 days).
Containerboard sales volume to external domestic and export customers decreased 9.9% to 431,000 tons for the year ended December 31, 2009 from 478,000 tons in 2008.
Outside sales of both corrugated products and containerboard began 2009 with significantly lower volumes compared to 2008 and steadily improved throughout the year.
Income from Operations Income from operations increased by $110.7 million, or 45.8%, for the year ended December 31, 2009 compared to 2008 primarily attributable to the alternative fuel mixture tax credit of $168.4 million described in Note 15 to the consolidated financial statements.
Excluding the alternative fuel mixture tax credit, income from operations decreased $57.8 million for full year 2009, which was primarily attributable to decreased sales prices of corrugated products and containerboard ($67.4 million), lower sales volume ($52.5 million) and increased labor and fringe benefit costs ($8.0 million), partially offset by decreased costs of energy ($24.5 million), transportation ($23.7 million), recycled fiber ($18.9 million) and wood fiber costs ($3.5 million).
