On October 15, 2015, a substantial amount of our interest in onshore acreage was sold, which is described in Note 2. The Company is active in the exploration, development and acquisition of oil and natural gas properties. Our interest in fields, leases, structures and equipment are primarily owned by the parent company, W&T Offshore, Inc.

Our production is sold utilizing month-to-month contracts that are based on bid prices. We also have receivables from joint interest owners on properties we operate and we may have the ability to withhold future revenue disbursements to recover amounts due us. We attempt to minimize our credit risk exposure to purchasers of our oil and natural gas, joint interest owners, derivative counterparties and other third-party entities through formal credit policies, monitoring procedures, and letters of credit or guaranties when considered necessary. We historically have not had any significant problems collecting our receivables, but with the decline in commodity prices, several oil and gas companies have filed for bankruptcy. We use the specific identification method of determining if an allowance for doubtful accounts is needed. As of December 31, 2015 and 2014, we recorded $2.5 million and $0.7 million, respectively, in the allowance for doubtful accounts. During 2015 and 2014, there was no usage of the amounts recorded for allowance for doubtful accounts. </p> <p

The adjustments resulted in Net cash provided by operating activities and Net cash used in investing activities to be decreased by $37.5 million for 2014 and increased by $1.4 million for 2013. Similar adjustments were made in the Condensed Consolidating Statements of Cash flow totaling the same amounts for the respective years. The adjustments did not affect the Consolidated Balance Sheets or the Consolidated Statements of Operations. </p></div> | |

From time to time, we use various derivative instruments to manage our exposure to commodity price risk from sales of oil and natural gas and interest rate risk from floating interest rates on our credit facility. Our derivative instruments currently consist of commodity swap contracts for oil. We do not enter into derivative instruments for speculative trading purposes. </p> <p style="margin-bottom:0pt;margin-top:12pt;text-indent:3.33%;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">Derivative instruments are recorded on the balance sheet as an asset or a liability at fair value. Changes in a derivative’s fair value are required to be recognized currently in earnings unless specific hedge accounting and documentation criteria are met at the time the derivative contract is entered into. We have elected not to designate our commodity derivatives as hedging instruments, therefore, all changes in fair value are recognized in earnings. </p></div> | |
