ADVANCE AUTO PARTS, INC.  AND SUBSIDIARIES NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS December 29, 2012, December 31, 2011 and January 1, 2011 (in thousands, except per share data) In June 2011, the FASB issued ASU No.2011-05 “Comprehensive Income – Presentation of Comprehensive Income.
” ASU 2011-05 requires comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements.
In both choices, an entity is required to present each component of net income along with total net income, each component of other comprehensive income along with a total for other comprehensive income, and a total amount for comprehensive income.
This update eliminates the option to present the components of other comprehensive income as part of the statement of changes in stockholders' equity.
The amendments in this update do not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income.
The amendments in this update should be applied retrospectively and is effective for interim and annual reporting periods beginning after December 15, 2011.
The Company adopted this guidance in the first quarter of 2012.
The adoption of ASU 2011-05 is for presentation purposes only and had no material impact on the Company’s consolidated financial statements.3.
Inventories, net: Merchandise Inventory The Company used the LIFO method of accounting for approximately 95% of inventories at both December 29, 2012 and December 31, 2011.
Under LIFO, the Company’s cost of sales reflects the costs of the most recently purchased inventories, while the inventory carrying balance represents the costs for inventories purchased in Fiscal 2012 and prior years.
The Company recorded a reduction to cost of sales of $24,087 and $29,554 in Fiscal 2012 and Fiscal 2010, respectively.
As a result of utilizing LIFO, the Company recorded an increase to cost of sales of $24,708 for Fiscal 2011, due to an increase in supply chain costs and inflationary pressures affecting certain product categories.
The Company’s overall costs to acquire inventory for the same or similar products have generally decreased historically as the Company has been able to leverage its continued growth, execution of merchandise strategies and realization of supply chain efficiencies.
Product Cores The remaining inventories are comprised of product cores, the non-consumable portion of certain parts and batteries, which are valued under the first-in, first-out ("FIFO") method.
Product cores are included as part of the Company's merchandise costs and are either passed on to the customer or returned to the vendor.
Because product cores are not subject to frequent cost changes like the Company's other merchandise inventory, there is no material difference when applying either the LIFO or FIFO valuation method.
Inventory Overhead Costs Purchasing and warehousing costs included in inventory at December 29, 2012 and December 31, 2011, were $134,258 and $126,840, respectively.
Inventory Balance and Inventory Reserves Inventory balances at the end of Fiscal 2012 and 2011 were as follows:

ITEM 7 / RESULTS OF OPERATIONS / LIABILITY FOR UNPAID CLAIMS AND CLAIMS ADJUSTMENT EXPENSE number of years it would take before the current ending loss reserves for these claims would be paid off using recent year average payments.
Many factors, such as aggressive settlement procedures, mix of business and level of coverage provided, have a significant effect on the amount of asbestos and environmental reserves and payments and the resulting survival ratio.
Additionally, we primarily base our determination of these reserves based on ground-up and top-down analyses, and not on survival ratios.
The following table presents survival ratios for asbestos and environmental claims, separately and combined, which were based upon a three-year average payment:

* Survival ratios are calculated consistent with the basis on historical reserve excluding the effects of the NICO reinsurance transaction.
AIG LIFE AND RETIREMENT AIG Life and Retirement presents its operating results in two operating segments — Retail and Institutional.
AIG Life and Retirement 2013 Highlights Premiums and deposits improved significantly in 2013 compared to 2012, primarily from strong sales of annuities in our Retirement Income Solutions and Fixed Annuities product lines and increased Retail Mutual Fund sales.
The improvement in Retirement Income Solutions resulted from our efforts to increase sales while managing risk by meeting the strong market demand for guaranteed features with innovative variable annuity products and expanded distribution.
As a result of the 2013 increase in premiums and deposits, net flows on investment products improved in 2013 compared to 2012.
Net flows from our Fixed Annuities product line, while still negative in 2013, improved compared to 2012 as a result of the modest rise in interest rates in the second half of 2013, which has increased the demand for fixed annuities.
Pre-tax operating income increased in 2013 compared to 2012 due to higher fee income from growth in variable annuity assets under management and active spread management in our interest rate sensitive product lines.
The increase in net investment income in 2013 compared to 2012 reflected higher alternative investment income, partially offset by fair value gains on ML II in 2012 that did not recur in 2013 and reinvestment of investment proceeds at lower rates.
Pre-tax operating income in 2013 also included a $153 million net increase from adjustments to update certain estimated gross profit assumptions used to amortize DAC and related items in our investment-oriented product lines.
These adjustments increased 2013 pre-tax operating income in our Retail operating segment by $198 million and decreased 2013 pre-tax operating income in our Institutional operating segment by $45 million.
See Critical Accounting Estimates — Estimated Gross Profits for Investment-Oriented Products (AIG Life and Retirement) for additional discussion of updated estimated gross profit assumptions.
Pre-tax operating income in 2012 also included $234 million of expenses related to the resolution of multi-state regulatory examinations of death claims practices and additional reserves for long-term care products and the GIC portfolio.
Pre-tax income increased in 2013 compared to 2012, reflecting the increases in pre-tax operating income as well as increases in legal settlements with financial institutions that participated in the creation, offering and sale of RMBS from which AIG and its subsidiaries realized losses during the financial crisis.
Additionally, pre-tax income increased due to net realized capital gains from continued investment sales to utilize capital loss carryforwards, which increased in 2013 compared to 2012.
However, reinvestment of these sales proceeds at lower current yields has contributed to lower future investment returns, reducing spreads in interest-sensitive product lines, and resulting in loss recognition for certain traditional products in 2013 and 2012, which was reported in Changes in benefit reserves and DAC, VOBA and SIA related to net realized capital gains (losses).
See AIG Life and Retirement Reserves and DAC — Other Reserve Changes for additional discussion of loss recognition.
Dividends and loan repayments paid by AIG Life and Retirement subsidiaries to AIG Parent increased to $4.4 billion in 2013 from $2.9 billion in 2012 from strong pre-tax income, as we continue to pursue capital efficiency and leverage our streamlined legal structure.
The increase in dividends in 2013 compared to 2012 is primarily due to legal settlement proceeds in 2013.
PART II Income Tax Benefit.
The variance was primarily due to a decrease in pretax income and the impact of PTCs for the renewables portfolio.
Matters Impacting Future Commercial Renewables Results Changes or variability in assumptions used in calculating the fair value of the Commercial Renewables reporting units for goodwill testing purposes, including but not limited to legislative actions related to tax credit extensions, long-term growth rates and discount rates could significantly impact the estimated fair value of the Commercial Renewables reporting units.
In the event of a significant decline in the estimated fair value of the Commercial Renewables reporting units, goodwill or other asset impairment charges could be recorded.
The carrying value of goodwill within Commercial Renewables was approximately $93 million at December 31, 2017.
Persistently low market pricing for wind resources, primarily in the Electric Reliability Council of Texas West market and the future expiration of tax incentives including ITCs and PTCs could result in adverse impacts to the future results of Commercial Renewables.
Within this Item 7, see the Tax Cuts and Jobs Act above as well as Liquidity and Capital Resources below for risks associated with the Tax Act.

## Table 2 ##
Year Ended December 31, 2017, as Compared to 2016 Other’s higher net expense was driven by the Tax Act, partially offset by prior year losses on forward-starting interest rate swaps and other costs related to the Piedmont acquisition, decreased severance expenses, prior year donations to the Duke Energy Foundation and insurance proceeds resulting from settlement of the shareholder litigation related to the Progress Energy merger.
The following is a detailed discussion of the variance drivers by line item.
Operating Revenues.
The increase was primarily due to higher OVEC (Ohio Valley Electric Corporation) revenues and prior year customer credits related to Piedmont merger commitments.
See Note 2 to the Consolidated Financial Statements, “Acquisitions and Dispositions,” for additional information.
Operating Expenses.
The decrease was primarily due to lower transaction and integration costs associated with the Piedmont acquisition, prior year severance expenses related to cost savings initiatives, donations to the Duke Energy Foundation in 2016 as well as prior year depreciation expense and other integration costs related to the Progress Energy merger.
The Duke Energy Foundation is a nonprofit organization funded by Duke Energy shareholders that makes charitable contributions to selected nonprofits and government subdivisions.
Other Income and Expenses.
The increase was primarily driven by insurance proceeds resulting from settlement of the shareholder litigation related to the Progress Energy merger, higher earnings from the equity method investment in NMC and increased returns on investments that fund certain employee benefit obligations.
Interest Expense.
The decrease was primarily due to prior year losses on forward-starting interest rate swaps related to Piedmont pre-acquisition financing, partially offset by higher interest costs on $3.75 billion of debt issued in August 2016 to fund the acquisition.
For additional information see Notes 2, 6 and 14 to the Consolidated Financial Statements, “Acquisitions and Dispositions,” “Debt and Credit Facilities” and “Derivatives and Hedging,” respectively.
Income Tax Benefit.
The variance was primarily due to the impact of the Tax Act and a decrease in pretax loss.

Year Ended December 31, 2016, as Compared to 2015 Other’s higher net expense was driven by costs related to the Piedmont acquisition, higher charitable donations and higher interest expense related to the Piedmont acquisition financing.
The following is a detailed discussion of the variance drivers by line item.
Operating Revenues.
The decrease was primarily due to customer credits recorded related to Piedmont merger commitments.
