Debt Disclosure [Abstract]
Debt Disclosure [Text Block]	Current and Long-Term Financing On May 31, 2012, HBB entered into an amended and restated credit agreement for a $115.0 million secured, floating-rate revolving credit facility (the “HBB Facility”). The HBB Facility expires in July 2017. Borrowings under the HBB Facility were used to repay HBB's previous term loan entered into in 2007. The obligations under the HBB Facility are secured by substantially all of HBB's assets. The approximate book value of HBB's assets held as collateral under the HBB Facility was $230 million as of September 30, 2012. The maximum availability under the HBB Facility is governed by a borrowing base derived from advance rates against eligible accounts receivable, inventory and trademarks of the borrowers, as defined in the HBB Facility. Adjustments to reserves booked against these assets, including inventory reserves, will change the eligible borrowing base and thereby impact the liquidity provided by the HBB Facility. A portion of the availability is denominated in Canadian dollars to provide funding to HBB's Canadian subsidiary. Borrowings bear interest at a floating rate, which can be a base rate or LIBOR, as defined in the HBB Facility, plus an applicable margin. The applicable margins, effective September 30, 2012, for base rate loans and LIBOR loans denominated in U.S. dollars were 0.00% and 1.50%, respectively. The applicable margins, effective September 30, 2012, for base rate loans and bankers' acceptance loans denominated in Canadian dollars was 0.00% and 1.50%, respectively. The HBB Facility also requires a fee of 0.375% per annum on the unused commitment. The margins and unused commitment fee under the HBB Facility are subject to quarterly adjustment based on average excess availability. At September 30, 2012, the borrowing base under the HBB Facility was $110.8 million. Borrowings outstanding under the HBB Facility were $52.3 million at September 30, 2012. Therefore, at September 30, 2012, the excess availability under the HBB Facility was $58.5 million. The floating rate of interest applicable to the HBB Facility at September 30, 2012 was 2.08% including the floating rate margin. The HBB Facility includes restrictive covenants, which, among other things, limit the payment of dividends to NACCO, subject to achieving availability thresholds. Dividends are limited to (i) $15.0 million from the closing date of the HBB Facility through December 31, 2012, so long as HBB has excess availability, as defined in the HBB Facility, of at least $30.0 million; (ii) the greater of $20.0 million or excess cash flow from the most recently ended fiscal year in each of the two twelve-month periods following the closing date of the HBB Facility, so long as HBB has excess availability under the HBB Facility of $25.0 million and maintains a minimum fixed charge coverage ratio of 1.0 to 1.0, as defined in the HBB Facility; and (iii) in such amounts as determined by HBB subsequent to the second anniversary of the closing date of the HBB Facility, so long as HBB has excess availability under the HBB Facility of $25.0 million. The HBB Facility also requires HBB to achieve a minimum fixed charge coverage ratio in certain circumstances, as defined in the HBB Facility. At September 30, 2012, HBB was in compliance with the financial covenants in the HBB Facility. HBB incurred fees and expenses of $1.2 million in the first nine months of 2012 related to the HBB Facility. These fees were deferred and are being amortized as interest expense over the term of the HBB Facility. On August 7, 2012, KC entered into an amended credit agreement for a five-year, $30.0 million secured revolving line of credit (the “KC Facility”). The KC Facility expires in August 2017. The obligations under the KC Facility are secured by substantially all assets of KC. The approximate book value of KC's assets held as collateral under the KC Facility was $85 million as of September 30, 2012. The maximum availability under the KC Facility is derived from a borrowing base formula using KC's eligible inventory and eligible credit card accounts receivable, as defined in the KC Facility. Borrowings bear interest at a floating rate plus a margin based on the excess availability under the agreement, as defined in the KC Facility, which can be either a base rate plus a margin of 1.00% or LIBOR plus a margin of 2.00%. The KC Facility also requires a fee of 0.375% per annum on the unused commitment. At September 30, 2012, the borrowing base under the KC Facility was $27.0 million. Borrowings outstanding under the KC Facility were $14.7 million at September 30, 2012. Therefore, at September 30, 2012, the excess availability under the KC Facility was $12.3 million. The floating rate of interest applicable to the KC Facility at September 30, 2012 was 2.95%, including the floating rate margin. The KC Facility allows for the payment of dividends to NACCO, subject to certain restrictions based on availability and meeting a fixed charge coverage ratio as described in the KC Facility. Dividends are limited to (i) $6.0 million in any twelve-month period, so long as KC has excess availability, as defined in the KC Facility, of at least $7.5 million after giving effect to such payment and maintaining a minimum fixed charge coverage ratio of 1.1 to 1.0, as defined in the KC Facility; (ii) $2.0 million in any twelve-month period, so long as KC has excess availability, as defined in the KC Facility, of at least $7.5 million after giving effect to such payment and (iii) in such amounts as determined by KC, so long as KC has excess availability under the KC Facility of $15.0 million after giving effect to such payment. KC incurred fees and expenses of $0.2 million in the first nine months of 2012 related to the KC Facility. These fees were deferred and are being amortized as interest expense over the term of the KC Facility.
