New Accounting Standards

In March 2016, the FASB issued ASU 2016-09, "Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting." Areas for simplification in this update involve several aspects of accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 is effective for interim and annual reporting periods beginning after December 15, 2016. We adopted the new guidance on January 1, 2017, requiring us to recognize all excess tax benefits and tax deficiencies related to stock compensation as income tax expense or benefit in the income statement. Excess tax benefits will be recognized regardless of whether the benefit reduces taxes payable in the current period, subject to normal valuation allowance considerations. Previous guidance resulted in credits to equity for such tax benefits and delayed recognition until the tax benefits reduced income taxes payable. This provision in the standard was applied using a modified retrospective transition method by means of a cumulative-effect adjustment to equity as of the beginning of the year of adoption. As of January 1, 2017, we recorded a $2.3 million reduction to our retained deficit and an increase in deferred income tax assets. In addition, on the modified retrospective basis, we have elected to discontinue estimating forfeitures expected to occur when determining the amount of compensation expense to be recognized in each period, resulting in an immaterial impact to our retained deficit and capital in excess of par. We do not anticipate this change will have a material impact toon our future results of operations. The presentation requirements for cash flows under the new standard were adopted on a

In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments." This standard introduces a new approach to estimating credit losses on certain types of financial instruments, including trade receivables, and modifies the impairment model for available-for-sale debt securities. ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, with early application permitted. We are currently assessing the impact that this standard will have on our Condensed Consolidated Financial Statements.

In October 2016, the FASB issued ASU 2016-16, "Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory." ASU 2016-16 clarifies that an entity should recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. ASU 2016-16 is effective for annual and interim reporting periods beginning after December 15, 2017, with early adoption permitted. We are currently assessing the impact that this standard will have on our Condensed Consolidated Financial Statements.

In January 2017, the FASB issued ASU 2017-04, "Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment." ASU 2017-04 simplifies the goodwill impairment testing by eliminating Step 2 from the goodwill impairment testing required, should an impairment be discovered during its annual or interim assessment. ASU 2017-04 is effective for annual or interim impairment tests beginning after December 15, 2019, with early adoption permitted. We plan to early adopt this standard on a prospective basis for our annual, and any interim, goodwill impairment testing performed after January 1, 2017, and this is considered a change in accounting principle. We are early adopting this standard as it will decrease the cost and complexity in applying current GAAP without significantly changing the usefulness of the information provided to users of our condensed consolidated financial statements.

The following table provides detail of selected balance sheet items:

Borrowings consist of the following:

At March 31,September 30, 2017, the available borrowing base under the ABL Facility was offset by a $0.5 million rent reserve.reserve and a $0.1 million natural gas derivative liability. The ABL Facility also provides for the issuance of up to $30.0 million of letters of credit which, when outstanding, are applied against the $100.0 million limit. At March 31,September 30, 2017, $7.0$7.2 million in letters of credit were outstanding. Remaining unused availability under the ABL Facility was $89.0$83.5 million at March 31,September 30, 2017, compared to $88.4 million at December 31, 2016.

For interim tax reporting, we estimate our annual effective tax rate and apply it to our year-to-date ordinary income. Tax jurisdictions with a projected or year-to-date loss for which a tax benefit cannot be realized are excluded from the annualized effective tax rate. The tax effects of unusual or infrequently occurring items, including changes in judgment about valuation allowances and effects of changes in tax laws or rates, are reported in the interim period in which they occur.

The Company and its subsidiaries are subject to examination by various countries' tax authorities. These examinations may lead to proposed or assessed adjustments to our taxes. In August 2016, one of our Mexican subsidiaries received a tax assessment from the Mexican tax authority (SAT) related to the audit of its 2010 tax year. The amount assessed was approximately 3 billion Mexican Pesos,pesos, which was equivalent to approximately $157 million USU.S. dollars as of the date of the assessment. The Company has filed an administrative appeal with SAT requesting that the assessment be fully nullified. We are awaiting the outcome of the appeal. Management, in consultation with external legal counsel, believes that if contested in the Mexican court system, it is more likely than not that the Company would prevail on all significant components of the assessment. Management intends to continue to vigorously contest all significant components of the assessment in the Mexican courts if they are not nullified at the administrative appeal level. We believe that our tax reserves related to uncertain tax positions are adequate at this time. There were no significant developments affecting this matter for the threenine months ended March 31,September 30, 2017.

See note 2 for details regarding the tax effects of adopting ASU 2016-09, "Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting," effective January 1, 2017.

We have pension plans covering the majority of our employees. Benefits generally are based on compensation and service for salaried employees and job grade and length of service for hourly employees. In addition, we have an unfunded supplemental employee retirement plan (SERP) that covers certain salaried U.S.-based employees of Libbey hired before January 1, 2006. The U.S. pension plans cover the salaried U.S.-based employees of Libbey hired before January 1, 2006, and most hourly U.S.-based employees (excluding employees hired at Shreveport after December 15, 2008 and at Toledo after September 30, 2010). Effective January 1, 2013, we ceased annual company contribution credits to the cash balance accounts in our Libbey U.S. Salaried Pension Plan and SERP. The non-U.S. pension plans cover the employees of our wholly owned subsidiary in Mexico and are unfunded.

The components of our net pension expense, including the SERP, are as follows:

We provide certain retiree health care and life insurance benefits covering our U.S. and Canadian salaried employees hired before January 1, 2004, and a majority of our union hourly employees (excluding employees hired at Shreveport after December 15, 2008 and at Toledo after September 30, 2010). Employees are generally eligible for benefits upon retirement and completion of a specified number of years of creditable service. Benefits for most hourly retirees are determined by collective bargaining. The U.S. non-pension, postretirementpost-retirement plans cover the hourly and salaried U.S.-based employees of Libbey (excluding those mentioned above). The non-U.S., non-pension, postretirementpost-retirement plans cover the retirees and active employees of Libbey who are located in Canada. The postretirementpost-retirement benefit plans are unfunded.

The provision for our non-pension postretirementpost-retirement benefit expense consists of the following:

The following table sets forth the computation of basic and diluted earnings (loss) per share:

When applicable, diluted shares outstanding includesinclude the dilutive impact of restricted stock units. Diluted shares also include the impact of eligible employee stock options, which are calculated based on the average share price for each fiscal period using the treasury stock method. As part of the adoption of ASU 2016-09 as of January 1, 2017, anticipated tax windfalls and shortfalls are no longer included in the calculation of assumed proceeds when applying the treasury stock method.

The following table provides the fair values of our derivative financial instruments for the periods presented:

Natural Gas Contracts

All of our derivatives for natural gas in the U.S. qualify and are designated as cash flow hedges at March 31,September 30, 2017. Hedge accounting is applied only when the derivative is deemed to be highly effective at offsetting changes in fair values or anticipated cash flows of the hedged item or transaction. For hedged forecasted transactions, hedge accounting is discontinued if the forecasted transaction is no longer probable to occur, and any previously deferred gains or losses would be recorded to earnings immediately. Changes in the effective portion of the fair value of these hedges are recorded in other comprehensive income (loss). The ineffective portion of the change in the fair value of a derivative designated as a cash flow hedge is recognized in other income (expense). As the natural gas contracts mature, the accumulated gains (losses) for the respective contracts are reclassified from accumulated other comprehensive loss to current expense in cost of sales in our Condensed Consolidated Statement of Operations.

Since October 1, 2014, our derivatives for natural gas in Mexico have not been designated as cash flow hedges. All mark-to-market changes on these derivatives are reflected in other income (expense).

We (received) paid additional cash related to natural gas derivative settlements of $(0.1)$0.1 million and $1.2$0.1 million in the three months ended March 31,September 30, 2017 and 2016, respectively, and $(0.2) million and $2.3 million for the nine months ended September 30, 2017 and 2016, respectively, due to the difference between the fixed unit rate of our natural gas contracts and the variable unit rate of our natural gas cost from suppliers. Based on our current valuation, we estimate that accumulated gainslosses for natural gas currently carried in accumulated other comprehensive loss that will be reclassified into earnings over the next twelve12 months will result in a $0.2 million gain inan immaterial impact to our Condensed Consolidated Statements of Operations.

The following table provides a summary of the effective portion of derivative gain (loss) recognized in other comprehensive income (loss) from our natural gas contracts:

Interest Rate Swap

On April 1, 2015, we executed an interest rate swap on our Term Loan B as part of our risk management strategy to mitigate the risks involved with fluctuating interest rates. The interest rate swap effectively converts $220.0 million of our Term Loan B debt from a variable interest rate to a 4.85 percent fixed interest rate, thus reducing the impact of interest rate changes on future income. The fixed rate swap became effective in January 2016 and expires in January 2020. This interest rate swap is valued using the market standard methodology of netting the discounted expected future variable cash receipts and the discounted future fixed cash payments. The variable cash receipts are based on an expectation of future interest rates derived from observed market interest rate forward curves.

Our interest rate swap qualifies and is designated as a cash flow hedge at March 31,September 30, 2017, and is accounted for under FASB ASC 815, "Derivatives and Hedging". Hedge accounting is applied only when the derivative is deemed to be highly effective at offsetting changes in fair values or anticipated cash flows of the hedged item or transaction. For hedged forecasted transactions, hedge accounting is discontinued if the forecasted transaction is no longer probable to occur, and any previously deferred gains or losses would beare recorded to earnings immediately. Changes in the effective portion of the fair value of these hedges are recorded in other comprehensive income (loss). The ineffective portion, if any, of the change in the fair value of a derivative designated as a cash flow hedge is recognized in other income (expense). Based on our current valuation, we estimate that accumulated losses currently carried in accumulated other comprehensive loss that will be reclassified into earnings over the next twelve12 months will result in $1.4$0.9 million of additional interest expense in our Condensed Consolidated Statements of Operations.

Currency Contracts

Gains (losses) on currency derivatives that were not designated as hedging instruments are recorded in other income (expense) as follows:

Accumulated other comprehensive loss, net of tax, is as follows:
