Financing Arrangements	Note 3. Financing Arrangements In addition to cash on hand, as well as cash generated from operations, the Company relies on its primary and Japan asset-based revolving credit facilities to manage seasonal fluctuations in liquidity and to provide additional liquidity when the Company’s operating cash flows are not sufficient to fund the Company’s requirements. As of June 30, 2017, the Company had $6,231,000 in borrowings outstanding under all facilities, $861,000 in outstanding letters of credit, and $61,959,000 in cash and cash equivalents. At June 30, 2016, the Company had $5,331,000 in borrowings outstanding under all facilities, $951,000 in outstanding letters of credit, and $67,619,000 in cash and cash equivalents. The combined maximum amount that could have been outstanding under all facilities on June 30, 2017, after letters of credit, was $174,340,000, resulting in total available liquidity including cash on hand of $236,299,000 compared to the maximum amount that could have been outstanding under all facilities on June 30, 2016, after letters of credit, of $148,712,000, resulting in total available liquidity including cash on hand of $216,331,000. Primary Asset-Based Revolving Credit Facility The Company's primary credit facility is a Loan and Security Agreement with Bank of America N.A. and other lenders (as amended, the “ABL Facility”), which provides a senior secured asset-based revolving credit facility of up to $230,000,000, comprised of a $160,000,000 U.S. facility, a $25,000,000 Canadian facility and a $45,000,000 United Kingdom facility, in each case subject to borrowing base availability under the applicable facility. The amounts outstanding under the ABL Facility are secured by certain assets, including cash (to the extent pledged by the Company), inventory and accounts receivable of the Company’s subsidiaries in the United States, Canada and the United Kingdom. As of June 30, 2017, the Company had no borrowings outstanding under the ABL Facility and $861,000 in outstanding letters of credit. The maximum amount of additional indebtedness (as defined by the ABL Facility) that could have been outstanding on June 30, 2017, after outstanding borrowings and letters of credit, was approximately $151,398,000. The maximum availability under the ABL Facility fluctuates with the general seasonality of the business and increases and decreases with changes in the Company’s inventory and accounts receivable balances. The maximum availability is at its highest during the first half of the year when the Company’s inventory and accounts receivable balances are higher and is lower during the second half of the year when the Company's inventory levels decrease and its accounts receivable decrease as a result of cash collections and lower sales. Average outstanding borrowings during the six months ended June 30, 2017 were $39,500,000, and the average amount available under the ABL Facility during the six months ended June 30, 2017, after outstanding borrowings and letters of credit, was approximately $121,065,000. Amounts borrowed under the ABL Facility may be repaid and borrowed as needed. The entire outstanding principal amount (if any) is due and payable on June 23, 2019. The ABL Facility includes certain restrictions including, among other things, restrictions on the incurrence of additional debt, liens, stock repurchases and other restricted payments, asset sales, investments, mergers, acquisitions and affiliate transactions. In addition, the ABL Facility imposes restrictions on the amount the Company could pay in annual cash dividends, including meeting certain restrictions on the amount of additional indebtedness and requirements to maintain a certain fixed charge coverage ratio under certain circumstances. The "fixed charge coverage ratio" is the ratio of (i) the 12-month trailing EBITDA (as defined in the ABL Facility) adjusted for capital expenditures and taxes paid, to (ii) interest expense and certain distributions paid in the trailing 12-month period adjusted for debt amortization, if any. These restrictions do not materially limit the Company's ability to pay future dividends at the current dividend rate. As of June 30, 2017, the Company was in compliance with all financial covenants of the ABL Facility. Additionally, the Company is subject to compliance with a fixed charge coverage ratio covenant during, and continuing 30 days after, any period in which the Company’s borrowing base availability, as amended, falls below $23,000,000. The Company’s borrowing base availability was above $23,000,000 during the six months ended June 30, 2017, and the Company was in compliance with the fixed charge coverage ratio as of June 30, 2017. Had the Company not been in compliance with the fixed charge coverage ratio as of June 30, 2017, the Company's maximum amount of additional indebtedness that could have been outstanding on June 30, 2017 would have been reduced by $23,000,000. The interest rate applicable to outstanding loans under the ABL Facility fluctuates depending on the Company’s “availability ratio," which is expressed as a percentage of (i) the average daily availability under the ABL Facility to (ii) the sum of the Canadian, the U.K. and the U.S. borrowing bases, as adjusted. The applicable margin for any month could be reduced by 0.25% if the Company’s availability ratio is greater than or equal to 67% and the Company’s “leverage ratio” (as defined below) is less than 4.0 to 1.0 as of the last day of the month for which financial statements have been delivered, so long as no default or event of default exists. The Company’s “leverage ratio” is the ratio of the amount of debt for borrowed money to the 12-month trailing EBITDA (as defined in the ABL Facility), each determined on a consolidated basis. At June 30, 2017, the Company’s trailing 12 month average interest rate applicable to its outstanding loans under the ABL Facility, not including the fees described below, was 3.03%. The ABL Facility provides for monthly fees ranging from 0.25% to 0.375% of the unused portion of the ABL Facility, depending on the prior month’s average daily balance of revolver loans and stated amount of letters of credit relative to lenders’ commitments. The fees incurred in connection with the origination and amendment of the ABL Facility totaled $5,021,000, which are amortized into interest expense over the term of the ABL Facility agreement. Unamortized fees at June 30, 2017 and December 31, 2016 totaled $1,065,000 and $1,297,000, respectively, of which $532,000 and $519,000 were included in other current assets, respectively, and $533,000 and $778,000 were included in other assets, respectively, in the accompanying consolidated condensed balance sheets. In July 2017, the Company amended the ABL Facility and entered into a stretch term loan facility ("Stretch Facility") for $60,000,000 that is in addition to the amounts available under the ABL Facility. Loans under the Stretch Facility ("Term Loans") bear interest at the current rates under the ABL Facility, plus 250 basis points. The Stretch Facility matures on the earlier of (i) four years from the commencement date of the facility and (ii) the maturity of the ABL Facility, and amortizes over a three year period, beginning in the second year of the facility. The Company must maintain a fixed charge coverage ratio of at least 1.0 to 1.0 and a leverage ratio of 4.0 to 1.0 or less at any time when there is $20,000,000 or more outstanding in Term Loans. The Stretch Facility is collateralized by the same assets as those under the ABL Facility, and is subject to certain restrictions, including placing liens on certain assets, in addition to limits on certain distributions. Japan ABL Facilities The Company has a separate asset-based loan and guarantee agreement, as amended, between its subsidiary in Japan and The Bank of Tokyo-Mitsubishi UFG, Ltd and The Development Bank of Japan, which provides a credit facility of up to 2,000,000,000 Yen (or U.S. $17,802,000, using the exchange rate in effect as of June 30, 2017) over a two-year term, subject to borrowing base availability under the facility. The amounts outstanding are secured by certain assets, including eligible inventory. The Company had 700,000,000 Yen (or U.S. $6,231,000) in borrowings outstanding under this facility as of June 30, 2017. The maximum amount that could have been outstanding at June 30, 2017 was 1,578,172,000 Yen (or U.S. $14,042,000). The facility also includes certain restrictions including covenants related to certain pledged assets and financial performance metrics. As of June 30, 2017, the Company was in compliance with these covenants. This facility is subject to an effective interest rate equal to TIBOR plus 0.25%. At June 30, 2017, the trailing 12-month average interest rate applicable to the Company's outstanding loans under this facility together with fees was 0.30%. During the first quarter of 2017, the Company entered into a second asset-based loan between its subsidiary in Japan and The Bank of Tokyo-Mitsubishi UFG, Ltd, which provides a credit facility of up to 1,000,000,000 Yen (or U.S. $8,898,000) over a 10-month term, subject to borrowing base availability under the facility. The amounts outstanding are secured by certain assets, including eligible accounts receivable. The Company had no borrowings outstanding under this facility as of June 30, 2017. The maximum amount that could have been outstanding at June 30, 2017 was 1,000,000,000 Yen (or U.S. $8,898,000). The facility also includes certain restrictions including covenants related to certain pledged assets and financial performance metrics. As of June 30, 2017, the Company was in compliance with these covenants. This facility is subject to an effective interest rate equal to TIBOR plus 0.75%. At June 30, 2017, the trailing 12-month average interest rate applicable to the Company's outstanding loans under this facility was 0.78%. Both facilities (the "Japan ABL Facilities") expire in January 2018.
