Redeemable Preferred Stock [Abstract]
Redeemable Preferred Stock	Note 7. Redeemable Preferred Stock Senior Redeemable Preferred Stock The Senior Redeemable Preferred Stock is senior to all other outstanding equity of the Company, including the Public Preferred Stock. The Series A-1 ranks on a parity with the Series A-2. The components of the authorized Senior Redeemable Preferred Stock are 1,250 shares of Series A-1 and 1,750 shares of Series A-2 Senior Redeemable Preferred Stock, each with $.01 par value. The Senior Redeemable Preferred Stock carries a cumulative per annum dividend rate of 14.125% of its liquidation value of $1,000 per share. The dividends are payable semiannually on June 30 and December 31 of each year. We have not declared dividends on our Senior Redeemable Preferred Stock since its issuance. The liquidation preference of the Senior Redeemable Preferred Stock is the face amount of the Series A-1 and A-2 ($1,000 per share), plus all accrued and unpaid dividends. Due to the terms of the Facility and of the Senior Redeemable Preferred Stock, we have been and continue to be precluded from paying any accrued and unpaid dividends on the Senior Redeemable Preferred Stock, other than described below. Certain holders of the Senior Redeemable Preferred Stock have entered into standby agreements whereby, among other things, those holders will not demand any payments in respect of dividends or redemptions of their instruments and the maturity dates of the instruments have been extended. As a result of such standby agreements, as of December 31, 2014, instruments held by Toxford Corporation ( "Toxford"), the holder of 76.4% of the Senior Redeemable Preferred Stock, will mature on February 28, 2017. On or about March 15, 2011, Mr. John Porter acquired a total of 75 shares and 105 shares of Series A-1 and Series A-2 Redeemable Preferred Stock, respectively, from other holders of the Senior Redeemable Preferred Stock. As of December 31, 2014, Mr. Porter held 6.3% of the Senior Redeemable Preferred Stock. In the aggregate, as of December 31, 2014, Mr. Porter and Toxford held a total of 163 shares and 228 shares of Series A-1 and Series A-2 Redeemable Preferred Stock, respectively, or 82.7% of the Senior Redeemable Preferred Stock. Mr. Porter is the sole stockholder of Toxford. Mr. Porter and Toxford own 39.3% of our Class A Common Stock. On May 11, 2012, the Facility was amended to allow for the redemption of Senior Redeemable Preferred Stock, under certain conditions, at a discount from par value plus accrued dividends of at least 10%, at an aggregate price not to exceed $4.0 million. On May 16, 2012, with the consent of the holders of the outstanding shares of Senior Redeemable Preferred Stock, 26.7% of the Senior Redeemable Preferred Stock with a carrying value of $2.2 million was redeemed for $2.0 million, resulting in a gain in the amount of approximately $0.2 million, representing a discount of 10%, which was recorded in other income on the consolidated statements of operations. Subsequent to such redemption, the total number of shares of Senior Redeemable Preferred Stock issued and outstanding was 677 shares and 947 shares for Series A-1 and Series A-2, respectively. On August 24, 2012, with the consent of the holders of the outstanding shares of Senior Redeemable Preferred Stock, 36.0% of the Senior Redeemable Preferred Stock with a carrying value of $2.2 million was redeemed for $2.0 million, resulting in a gain in the amount of approximately $0.2 million, representing a discount of 10%, which was recorded in other income on the consolidated statements of operations. Subsequent to such redemption, the total number of shares of Senior Redeemable Preferred Stock issued and outstanding was 433 shares and 607 shares for Series A-1 and Series A-2, respectively. On June 11, 2013, the Facility was further amended to allow for the redemption of Senior Redeemable Preferred Stock, under certain conditions, at a discount from par value plus accrued dividends of at least 10%, at an aggregate price not to exceed $2.0 million. On June 14, 2013, with the consent of the holders of the outstanding shares of Senior Redeemable Preferred Stock, 54.5% of the Senior Redeemable Preferred Stock with a carrying value of $2.2 million was redeemed for $2.0 million, resulting in a gain in the amount of approximately $0.2 million, representing a discount of 10%, which was recorded in other income on the condensed consolidated statements of operations. Subsequent to such redemption, the total number of shares of Senior Redeemable Preferred Stock issued and outstanding was 197 shares and 276 shares for Series A-1 and Series A-2, respectively. At December 31, 2014 and 2013, the total number of shares of Senior Redeemable Preferred Stock issued and outstanding was 197 shares and 276 shares for Series A-1 and Series A-2, respectively. Due to the limitations, contractual restrictions, and agreements described above, the Senior Redeemable Preferred Stock is classified as noncurrent as of December 31, 2014. At December 31, 2014 and 2013, cumulative undeclared, unpaid dividends relating to Senior Redeemable Preferred stock totaled $1.5 million and $1.4 million, respectively. We accrued dividends on the Senior Redeemable Preferred Stock of $67,000, $103,000 and $228,000 for the years ended December 31, 2014, 2013, and 2012, respectively, which were reported as interest expense. Prior to the effective date of ASC 480-10, "Distinguishing Liabilities from Equity," on July 1, 2003, such dividends were charged to stockholders' deficit. 12% Cumulative Exchangeable Redeemable Preferred Stock A maximum of 6,000,000 shares of the Public Preferred Stock, par value $.01 per share, has been authorized for issuance. We initially issued 2,858,723 shares of the Public Preferred Stock pursuant to the acquisition of the Company during fiscal year 1990. The Public Preferred Stock was recorded at fair value on the date of original issue, November 21, 1989, and we made periodic accretions under the interest method of the excess of the redemption value over the recorded value. We adjusted our estimate of accrued accretion in the amount of $1.5 million in the second quarter of 2006. The Public Preferred Stock was fully accreted as of December 2008. We declared stock dividends totaling 736,863 shares in 1990 and 1991. Since 1991, no other dividends, in stock or cash, have been declared. In November 1998, we retired 410,000 shares of the Public Preferred Stock. The total number of shares issued and outstanding at December 31, 2014 and 2013, was 3,185,586. The Public Preferred Stock is quoted as TLSRP on the OTCQB marketplace and the OTC Bulletin Board. Since 1991, no dividends were declared or paid on our Public Preferred Stock, based upon our interpretation of restrictions in our Articles of Amendment and Restatement, limitations in the terms of the Public Preferred Stock instrument, specific dividend payment restrictions in the Facility entered into with Wells Fargo to which the Public Preferred Stock is subject, other senior obligations, and Maryland law limitations in existence prior to October 1, 2009. Pursuant to their terms, we were scheduled, but not required, to redeem the Public Preferred Stock in five annual tranches during the period 2005 through 2009. However, due to our substantial senior obligations, limitations set forth in the covenants in the Facility, foreseeable capital and operational requirements, and restrictions and prohibitions of our Articles of Amendment and Restatement, we were unable to meet the redemption schedule set forth in the terms of the Public Preferred Stock. Moreover, the Public Preferred Stock is not payable on demand, nor callable, for failure to redeem the Public Preferred Stock in accordance with the redemption schedule set forth in the instrument. Therefore, we classify these securities as noncurrent liabilities in the consolidated balance sheets as of December 31, 2014 and 2013. We are parties with certain of our subsidiaries to the Facility agreement with Wells Fargo, whose term expires on April 1, 2016. Under the Facility, we agreed that, so long as any credit under the Facility is available and until full and final payment of the obligations under the Facility, we would not make any distribution or declare or pay any dividends (other than common stock) on our stock, or purchase, acquire, or redeem any stock, or exchange any stock for indebtedness, or retire any stock. Accordingly, as stated above, we will continue to classify the entirety of our obligation to redeem the Public Preferred Stock as a long-term obligation. The Facility prohibits, among other things, the redemption of any stock, common or preferred, other than as described above. The Public Preferred Stock by its terms cannot be redeemed if doing so would violate the terms of an agreement regarding the borrowing of funds or the extension of credit which is binding upon us or any of our subsidiaries, and it does not include any other provisions that would otherwise require any acceleration of the redemption of or amortization payments with respect to the Public Preferred Stock. Thus, the Public Preferred Stock is not and will not be due on demand, nor callable, within 12 months from December 31, 2014. This classification is consistent with ASC 210-10, "Balance Sheet" and 470-10, "Debt" and the FASB ASC Master Glossary definition of "Current Liabilities." ASC 210-10 and the FASB ASC Master Glossary define current liabilities as follows: The term current liabilities is used principally to designate obligations whose liquidation is reasonably expected to require the use of existing resources properly classifiable as current assets, or the creation of other current liabilities. As a balance sheet category, the classification is intended to include obligations for items which have entered into the operating cycle, such as payables incurred in the acquisition of materials and supplies to be used in the production of goods or in providing services to be offered for sale; collections received in advance of the delivery of goods or performance of services; and debts that arise from operations directly related to the operating cycle, such as accruals for wages, salaries, commissions, rentals, royalties, and income and other taxes. Other liabilities whose regular and ordinary liquidation is expected to occur within a relatively short period of time, usually twelve months, are also intended for inclusion, such as short-term debts arising from the acquisition of capital assets, serial maturities of long-term obligations, amounts required to be expended within one year under sinking fund provisions, and agency obligations arising from the collection or acceptance of cash or other assets for the account of third persons. ASC 470-10 provides the following: The current liability classification is also intended to include obligations that, by their terms, are due on demand or will be due on demand within one year (or operating cycle, if longer) from the balance sheet date, even though liquidation may not be expected within that period. It is also intended to include long-term obligations that are or will be callable by the creditor either because the debtor's violation of a provision of the debt agreement at the balance sheet date makes the obligation callable or because the violation, if not cured within a specified grace period, will make the obligation callable. If, pursuant to the terms of the Public Preferred Stock, we do not redeem the Public Preferred Stock in accordance with the scheduled redemptions described above, the terms of the Public Preferred Stock require us to discharge our obligation to redeem the Public Preferred Stock as soon as we are financially capable and legally permitted to do so. Therefore, by its very terms, the Public Preferred Stock is not due on demand or callable for failure to make a scheduled payment pursuant to its redemption provisions and is properly classified as a noncurrent liability. We pay dividends on the Public Preferred Stock when and if declared by the Board of Directors. The Public Preferred Stock accrues a semi-annual dividend at the annual rate of 12% ($1.20) per share, based on the liquidation preference of $10 per share and is fully cumulative. Dividends in additional shares of the Public Preferred Stock for 1990 and 1991 were paid at the rate of 6% of a share for each $.60 of such dividends not paid in cash. For the cash dividends payable since December 1, 1995, we have accrued $88.2 million and $84.4 million as of December 31, 2014 and 2013, respectively. We accrued dividends on the Public Preferred Stock of $3.8 million for the years ended December 31, 2014, 2013, and 2012, which was recorded as interest expense. Prior to the effective date of ASC 480-10 on July 1, 2003, such dividends were charged to stockholders' accumulated deficit. The carrying value of the accrued Paid-in-Kind ("PIK") dividends on the Public Preferred Stock for the period 1992 through June 1995 was $4.0 million. Had we accrued such dividends on a cash basis for this time period, the total amount accrued would have been $15.1 million. However, as a result of the redemption of the 410,000 shares of the Public Preferred Stock in November 1998, such amounts were reduced and adjusted to $3.5 million and $13.4 million, respectively. Our Articles of Amendment and Restatement, Section 2(a) states, "Any dividends payable with respect to the Exchangeable Preferred Stock ("Public Preferred Stock") during the first six years after the Effective Date (November 20, 1989) may be paid (subject to restrictions under applicable state law), in the sole discretion of the Board of Directors, in cash or by issuing additional fully paid and nonassessable shares of Exchangeable Preferred Stock …". Accordingly, the Board had the discretion to pay the dividends for the referenced period in cash or by the issuance of additional shares of Public Preferred Stock. During the period in which we stated our intent to pay PIK dividends, we stated our intention to amend our Charter to permit such payment by the issuance of additional shares of Public Preferred Stock. In consequence, as required by applicable accounting requirements, the accrual for these dividends was recorded at the estimated fair value (as the average of the ask and bid prices) on the dividend date of the shares of Public Preferred Stock that would have been (but were not) issued. This accrual was $9.9 million lower than the accrual would be if the intent was only to pay the dividend in cash, at that date or any later date. In May 2006, the Board concluded that the accrual of PIK dividends for the period 1992 through June 1995 was no longer appropriate. Since 1995, we have disclosed in the footnotes to our audited financial statements the carrying value of the accrued PIK dividends on the Public Preferred Stock for the period 1992 through June 1995 as $4.0 million, and that had we accrued cash dividends during this time period, the total amount accrued would have been $15.1 million. As stated above, such amounts were reduced and adjusted to $3.5 million and $13.4 million, respectively, due to the redemption of 410,000 shares of the Public Preferred Stock in November 1998. On May 12, 2006, the Board voted to confirm that our intent with respect to the payment of dividends on the Public Preferred Stock for this period changed from its previously stated intent to pay PIK dividends to that of an intent to pay cash dividends. We therefore changed the accrual from $3.5 million to $13.4 million, the result of which was to increase our negative shareholder equity by the $9.9 million difference between those two amounts, by recording an additional $9.9 million charge to interest expense for the second quarter of 2006, resulting in a balance of $120.1 million and $116.3 million for the principal amount and all accrued dividends on the Public Preferred Stock as of December 31, 2014 and 2013, respectively. This action is considered a change in assumption that results in a change in accounting estimate as defined in ASC 250-10, which sets forth guidance concerning accounting changes and error corrections.

Senior Redeemable Preferred Stock

The Senior Redeemable Preferred Stock is senior to all other outstanding equity of the Company, including the Public Preferred Stock. The Series A-1 ranks on a parity with the Series A-2. The components of the authorized Senior Redeemable Preferred Stock are 1,250 shares of Series A-1 and 1,750 shares of Series A-2 Senior Redeemable Preferred Stock, each with $.01 par value. The Senior Redeemable Preferred Stock carries a cumulative per annum dividend rate of 14.125% of its liquidation value of $1,000 per share. The dividends are payable semiannually on June 30 and December 31 of each year. We have not declared dividends on our Senior Redeemable Preferred Stock since its issuance. The liquidation preference of the Senior Redeemable Preferred Stock is the face amount of the Series A-1 and A-2 ($1,000 per share), plus all accrued and unpaid dividends.

Due to the terms of the Facility and of the Senior Redeemable Preferred Stock, we have been and continue to be precluded from paying any accrued and unpaid dividends on the Senior Redeemable Preferred Stock, other than described below. Certain holders of the Senior Redeemable Preferred Stock have entered into standby agreements whereby, among other things, those holders will not demand any payments in respect of dividends or redemptions of their instruments and the maturity dates of the instruments have been extended. As a result of such standby agreements, as of December 31, 2014, instruments held by Toxford Corporation ( "Toxford"), the holder of 76.4% of the Senior Redeemable Preferred Stock, will mature on February 28, 2017.

On or about March 15, 2011, Mr. John Porter acquired a total of 75 shares and 105 shares of Series A-1 and Series A-2 Redeemable Preferred Stock, respectively, from other holders of the Senior Redeemable Preferred Stock.

On May 11, 2012, the Facility was amended to allow for the redemption of Senior Redeemable Preferred Stock, under certain conditions, at a discount from par value plus accrued dividends of at least 10%, at an aggregate price not to exceed $4.0 million. On May 16, 2012, with the consent of the holders of the outstanding shares of Senior Redeemable Preferred Stock, 26.7% of the Senior Redeemable Preferred Stock with a carrying value of $2.2 million was redeemed for $2.0 million, resulting in a gain in the amount of approximately $0.2 million, representing a discount of 10%, which was recorded in other income on the consolidated statements of operations.

On August 24, 2012, with the consent of the holders of the outstanding shares of Senior Redeemable Preferred Stock, 36.0% of the Senior Redeemable Preferred Stock with a carrying value of $2.2 million was redeemed for $2.0 million, resulting in a gain in the amount of approximately $0.2 million, representing a discount of 10%, which was recorded in other income on the consolidated statements of operations. Subsequent to such redemption, the total number of shares of Senior Redeemable Preferred Stock issued and outstanding was 433 shares and 607 shares for Series A-1 and Series A-2, respectively.

On June 11, 2013, the Facility was further amended to allow for the redemption of Senior Redeemable Preferred Stock, under certain conditions, at a discount from par value plus accrued dividends of at least 10%, at an aggregate price not to exceed $2.0 million. On June 14, 2013, with the consent of the holders of the outstanding shares of Senior Redeemable Preferred Stock, 54.5% of the Senior Redeemable Preferred Stock with a carrying value of $2.2 million was redeemed for $2.0 million, resulting in a gain in the amount of approximately $0.2 million, representing a discount of 10%, which was recorded in other income on the condensed consolidated statements of operations. Subsequent to such redemption, the total number of shares of Senior Redeemable Preferred Stock issued and outstanding was 197 shares and 276 shares for Series A-1 and Series A-2, respectively.

At December 31, 2014 and 2013, the total number of shares of Senior Redeemable Preferred Stock issued and outstanding was 197 shares and 276 shares for Series A-1 and Series A-2, respectively. Due to the limitations, contractual restrictions, and agreements described above, the Senior Redeemable Preferred Stock is classified as noncurrent as of December 31, 2014.

At December 31, 2014 and 2013, cumulative undeclared, unpaid dividends relating to Senior Redeemable Preferred stock totaled $1.5 million and $1.4 million, respectively. We accrued dividends on the Senior Redeemable Preferred Stock of $67,000, $103,000 and $228,000 for the years ended December 31, 2014, 2013, and 2012, respectively, which were reported as interest expense. Prior to the effective date of ASC 480-10, "Distinguishing Liabilities from Equity," on July 1, 2003, such dividends were charged to stockholders' deficit.

12% Cumulative Exchangeable Redeemable Preferred Stock

A maximum of 6,000,000 shares of the Public Preferred Stock, par value $.01 per share, has been authorized for issuance. We initially issued 2,858,723 shares of the Public Preferred Stock pursuant to the acquisition of the Company during fiscal year 1990. The Public Preferred Stock was recorded at fair value on the date of original issue, November 21, 1989, and we made periodic accretions under the interest method of the excess of the redemption value over the recorded value. We adjusted our estimate of accrued accretion in the amount of $1.5 million in the second quarter of 2006. The Public Preferred Stock was fully accreted as of December 2008. We declared stock dividends totaling 736,863 shares in 1990 and 1991. Since 1991, no other dividends, in stock or cash, have been declared. In November 1998, we retired 410,000 shares of the Public Preferred Stock. The total number of shares issued and outstanding at December 31, 2014 and 2013, was 3,185,586. The Public Preferred Stock is quoted as TLSRP on the OTCQB marketplace and the OTC Bulletin Board.

Since 1991, no dividends were declared or paid on our Public Preferred Stock, based upon our interpretation of restrictions in our Articles of Amendment and Restatement, limitations in the terms of the Public Preferred Stock instrument, specific dividend payment restrictions in the Facility entered into with Wells Fargo to which the Public Preferred Stock is subject, other senior obligations, and Maryland law limitations in existence prior to October 1, 2009. Pursuant to their terms, we were scheduled, but not required, to redeem the Public Preferred Stock in five annual tranches during the period 2005 through 2009. However, due to our substantial senior obligations, limitations set forth in the covenants in the Facility, foreseeable capital and operational requirements, and restrictions and prohibitions of our Articles of Amendment and Restatement, we were unable to meet the redemption schedule set forth in the terms of the Public Preferred Stock. Moreover, the Public Preferred Stock is not payable on demand, nor callable, for failure to redeem the Public Preferred Stock in accordance with the redemption schedule set forth in the instrument. Therefore, we classify these securities as noncurrent liabilities in the consolidated balance sheets as of December 31, 2014 and 2013.

We are parties with certain of our subsidiaries to the Facility agreement with Wells Fargo, whose term expires on April 1, 2016. Under the Facility, we agreed that, so long as any credit under the Facility is available and until full and final payment of the obligations under the Facility, we would not make any distribution or declare or pay any dividends (other than common stock) on our stock, or purchase, acquire, or redeem any stock, or exchange any stock for indebtedness, or retire any stock.

Accordingly, as stated above, we will continue to classify the entirety of our obligation to redeem the Public Preferred Stock as a long-term obligation. The Facility prohibits, among other things, the redemption of any stock, common or preferred, other than as described above. The Public Preferred Stock by its terms cannot be redeemed if doing so would violate the terms of an agreement regarding the borrowing of funds or the extension of credit which is binding upon us or any of our subsidiaries, and it does not include any other provisions that would otherwise require any acceleration of the redemption of or amortization payments with respect to the Public Preferred Stock. Thus, the Public Preferred Stock is not and will not be due on demand, nor callable, within 12 months from December 31, 2014. This classification is consistent with ASC 210-10, "Balance Sheet" and 470-10, "Debt" and the FASB ASC Master Glossary definition of "Current Liabilities."

ASC 210-10 and the FASB ASC Master Glossary define current liabilities as follows: The term current liabilities is used principally to designate obligations whose liquidation is reasonably expected to require the use of existing resources properly classifiable as current assets, or the creation of other current liabilities. As a balance sheet category, the classification is intended to include obligations for items which have entered into the operating cycle, such as payables incurred in the acquisition of materials and supplies to be used in the production of goods or in providing services to be offered for sale; collections received in advance of the delivery of goods or performance of services; and debts that arise from operations directly related to the operating cycle, such as accruals for wages, salaries, commissions, rentals, royalties, and income and other taxes. Other liabilities whose regular and ordinary liquidation is expected to occur within a relatively short period of time, usually twelve months, are also intended for inclusion, such as short-term debts arising from the acquisition of capital assets, serial maturities of long-term obligations, amounts required to be expended within one year under sinking fund provisions, and agency obligations arising from the collection or acceptance of cash or other assets for the account of third persons.

ASC 470-10 provides the following: The current liability classification is also intended to include obligations that, by their terms, are due on demand or will be due on demand within one year (or operating cycle, if longer) from the balance sheet date, even though liquidation may not be expected within that period. It is also intended to include long-term obligations that are or will be callable by the creditor either because the debtor's violation of a provision of the debt agreement at the balance sheet date makes the obligation callable or because the violation, if not cured within a specified grace period, will make the obligation callable.

If, pursuant to the terms of the Public Preferred Stock, we do not redeem the Public Preferred Stock in accordance with the scheduled redemptions described above, the terms of the Public Preferred Stock require us to discharge our obligation to redeem the Public Preferred Stock as soon as we are financially capable and legally permitted to do so. Therefore, by its very terms, the Public Preferred Stock is not due on demand or callable for failure to make a scheduled payment pursuant to its redemption provisions and is properly classified as a noncurrent liability.

We pay dividends on the Public Preferred Stock when and if declared by the Board of Directors. The Public Preferred Stock accrues a semi-annual dividend at the annual rate of 12% ($1.20) per share, based on the liquidation preference of $10 per share and is fully cumulative. Dividends in additional shares of the Public Preferred Stock for 1990 and 1991 were paid at the rate of 6% of a share for each $.60 of such dividends not paid in cash. For the cash dividends payable since December 1, 1995, we have accrued $88.2 million and $84.4 million as of December 31, 2014 and 2013, respectively. We accrued dividends on the Public Preferred Stock of $3.8 million for the years ended December 31, 2014, 2013, and 2012, which was recorded as interest expense. Prior to the effective date of ASC 480-10 on July 1, 2003, such dividends were charged to stockholders' accumulated deficit.

The carrying value of the accrued Paid-in-Kind ("PIK") dividends on the Public Preferred Stock for the period 1992 through June 1995 was $4.0 million. Had we accrued such dividends on a cash basis for this time period, the total amount accrued would have been $15.1 million. However, as a result of the redemption of the 410,000 shares of the Public Preferred Stock in November 1998, such amounts were reduced and adjusted to $3.5 million and $13.4 million, respectively. Our Articles of Amendment and Restatement, Section 2(a) states, "Any dividends payable with respect to the Exchangeable Preferred Stock ("Public Preferred Stock") during the first six years after the Effective Date (November 20, 1989) may be paid (subject to restrictions under applicable state law), in the sole discretion of the Board of Directors, in cash or by issuing additional fully paid and nonassessable shares of Exchangeable Preferred Stock …". Accordingly, the Board had the discretion to pay the dividends for the referenced period in cash or by the issuance of additional shares of Public Preferred Stock. During the period in which we stated our intent to pay PIK dividends, we stated our intention to amend our Charter to permit such payment by the issuance of additional shares of Public Preferred Stock. In consequence, as required by applicable accounting requirements, the accrual for these dividends was recorded at the estimated fair value (as the average of the ask and bid prices) on the dividend date of the shares of Public Preferred Stock that would have been (but were not) issued. This accrual was $9.9 million lower than the accrual would be if the intent was only to pay the dividend in cash, at that date or any later date.

In May 2006, the Board concluded that the accrual of PIK dividends for the period 1992 through June 1995 was no longer appropriate. Since 1995, we have disclosed in the footnotes to our audited financial statements the carrying value of the accrued PIK dividends on the Public Preferred Stock for the period 1992 through June 1995 as $4.0 million, and that had we accrued cash dividends during this time period, the total amount accrued would have been $15.1 million.

We therefore changed the accrual from $3.5 million to $13.4 million, the result of which was to increase our negative shareholder equity by the $9.9 million difference between those two amounts, by recording an additional $9.9 million charge to interest expense for the second quarter of 2006, resulting in a balance of $120.1 million and $116.3 million for the principal amount and all accrued dividends on the Public Preferred Stock as of December 31, 2014 and 2013, respectively. This action is considered a change in assumption that results in a change in accounting estimate as defined in ASC 250-10, which sets forth guidance concerning accounting changes and error corrections.
