Value Added Tax Receivable [Abstract]
Mexican IVA taxes receivable	11.Mexican IVA taxes receivable Included in other assets are tax receivables due from the Mexican government for value-added taxes (IVA) paid in advance. CDM is charged IVA by vendors on certain expenditures in Mexico, which, insofar as they relate to the exportation of goods, translate into IVA amounts receivable from the Mexican government. As of January 31, 2019 and October 31, 2018, CDM IVA receivables totaled $24.0 million and $21.9 million. Historically, CDM received IVA refund payments from the Mexican tax authorities on a timely basis. Beginning in fiscal 2014 and continuing into fiscal 2019, however, the tax authorities began carrying out more detailed reviews of our refund requests and our supporting documentation. Additionally, they are also questioning the refunds requested attributable to IVA paid to certain suppliers that allegedly did not fulfill their own tax obligations. We believe these factors and others have contributed to delays in the processing of IVA claims by the Mexican tax authorities. Currently, we are in the process of collecting such balances through regular administrative processes, but certain amounts may ultimately need to be recovered via legal means. During the first quarter of fiscal 2017, tax authorities informed us that their internal opinion, based on the information provided by the local SAT office in Uruapan, considers that CDM is not properly documented relative to its declared tax structure and therefore CDM cannot claim the refundable IVA balance. CDM has strong arguments and supporting documentation to sustain its declared tax structure for IVA and income tax purposes. CDM started an administrative appeal for the IVA related to the request of the months of July, August and September of 2015 (the “2015 Appeal”) in order to assert its argument that CDM is properly documented and to therefore change the SAT’s internal assessment. In August 2018, we received a favorable ruling from the SAT’s central legal department in Mexico City on the 2015 Appeal indicating that they believe CDM’s legal interpretation of its declared tax structure is indeed accurate. While favorable on this central matter of CDMs declared tax structure, the ruling, however, still does not recognize the taxpayers right to a full refund for the IVA related to the months of July, August and September 2015. Therefore, CDM may need to file a substance-over-form annulment suit in the Federal Tax Court to recover its full refund for IVA over the subject period. In spite of the favorable ruling from the SAT’s central legal department in Mexico City, as discussed above, the local SAT office in Uruapan continues to believe that CDM is not properly documented relative to its declared tax structure. As a result, they believe CDM cannot claim certain refundable IVA balances, specifically in regards to our IVA refunds related to the months of January through June of 2013. CDM has strong arguments and supporting documentation to sustain its declared tax structure for IVA and income tax purposes. CDM started an administrative appeal for the IVA related to the request of the months of January, February of March of 2013 and for the period of April, May and June of 2013 our global tax law advisory firm with offices throughout Mexico is working in the administrative appeal through which CDM will challenge the determination made by the tax authorities, which must be filed no later than March 8, 2019. We believe that our operations in Mexico are properly documented. Furthermore, our internationally recognized tax advisors believe that there are legal grounds to prevail in the Federal Tax Court and that therefore, the Mexican tax authorities will ultimately authorize the refund of the corresponding IVA amounts.
