Customer deposits: We signed agreements with certain customers related to our Fiber Optics segment pursuant to which they have received an allocation of our finished goods inventory that was not damaged by the Thailand flood and have started to receive a percentage of output from our new production lines placed into service. As consideration, we received $6.8 million as partial prepayments for future product shipments, of which none is outstanding as of June 30, 2013. The remaining customer deposits are in the normal course of business.

Capital lease obligations: As of September 30, 2012, we capitalized the cost of our new manufacturing lines of approximately $5.2 million and recorded an equipment capital lease obligation of $4.4 million, net of equipment deposits. In addition, during the nine months ended June 30, 2013, we capitalized an additional $1.2 million of manufacturing lines and recorded a corresponding amount of capital lease obligations. See Note 9 - Impact from Thailand Flood for additional disclosures related to the impact of the Thailand flood on our operations.

Severance and restructuring accruals: In August 2012, Mr. Reuben Richards, Jr. proposed to the Board to step-down from his position as the Company's Executive Chairman and all other positions he held as an officer or employee of the Company and its affiliates, effective as of September 30, 2012. Mr. Richards remained as Chairman of the Board and a member of the Board.

The Company and Mr. Richards entered into a separation agreement and general release, dated August 6, 2012 (Separation Agreement), which includes mutual releases by Mr. Richards and the Company of all claims related to Mr. Richards' employment and service relationship with, and termination of employment and service from, the Company. Under the terms of the Separation Agreement, Mr. Richards acknowledged and agreed that the restrictive covenants contained in his employment agreement would remain in full force and effect. The separation agreement provides for among other things, the continuation of his base salary for 88 weeks, benefits for 18 months, and immediate vesting of all his outstanding non-vested equity awards. These payments are not contingent upon any future service by Mr. Richards. In fiscal year 2012, we recorded a charge of $1.1 million related to Mr. Richards' separation agreement.

Our restructuring-related accrual specifically relates to the Separation Agreement and non-cancelable obligations associated with an abandoned leased facility. Expense related to severance and restructuring accruals is included in sales, general, and administrative expense on our statement of operations and comprehensive income (loss). The following table summarizes the changes in the severance and restructuring-related accrual accounts:
