Commitments and Contingencies Disclosure [Abstract]
Legal Matters	LEGAL MATTERS We may be the subject of threatened or pending legal actions and contingencies in the normal course of conducting our business. We provide for costs related to these matters when a loss is probable and the amount can be reasonably estimated. The effect of the outcome of these matters on our future results of operations and liquidity cannot be predicted because any such effect depends on future results of operations and the amount or timing of the resolution of such matters. While it is not possible to predict the future outcome of such matters, we believe that the ultimate resolution of such individual or aggregated matters will not have a material adverse effect on our consolidated financial position, results of operations, or cash flows. For certain types of claims, we maintain insurance coverage for personal injury and property damage, product liability and other liability coverages in amounts and with deductibles that we believe are prudent, but there can be no assurance that these coverages will be applicable or adequate to cover adverse outcomes of claims or legal proceedings against us. On November 26, 2013, we announced the sale of our pool products business for a cash purchase price of $5.2 million. Under the terms of the Purchase Agreement, we sold substantially all of the assets associated with the pool products business and the buyer assumed certain related liabilities. The Purchase Agreement provided for an escrow of $500 thousand of the purchase price to secure customary indemnification obligations with respect to our representations, warranties, covenants and other obligations under the Purchase Agreement. Under the terms of the Purchase Agreement, the first of five $100 thousand scheduled escrow releases commenced on March 25, 2014, and was to continue on the 25th day of each of the next four subsequent months. As of December 31, 2015 and 2014, $200 thousand of the cash held in escrow had been released to us and $300 thousand remained in escrow subject to the resolution of outstanding buyer claims. The Purchase Agreement provides that all disputes related to the sale must be resolved through binding arbitration. On February 18, 2015, the buyer filed a claim with the American Arbitration Association (“AAA”) asserting claims for damages of $780 thousand under the Purchase Agreement and relating to product development, which was amended on September 1, 2015 to assert damages of $1.6 million. We believed the claims were without merit and asserted a counterclaim in the arbitration for the $300 thousand that remained in escrow. On March 18, 2016, a settlement agreement was executed for this claim and the funds in the escrow account, plus the interest earned on the account, were released to the buyer.
