Dividends and interest income includes distributions from The Amalgamated Sugar Company LLC of $16.9 million in 2018. Securities transactions, net in 2018 includes a $12.5 million gain on the sale of our investment in The Amalgamated Sugar Company LLC. See Note 6.

Insurance recoveries relate primarily to amounts NL received from certain of its former insurance carriers, and relate principally to the recovery of prior lead pigment and asbestos litigation defense costs. NL has agreements with certain of its former insurance carriers pursuant to which the carriers reimburse it for a portion of its future lead pigment litigation defense costs, and one such carrier reimburses NL for a portion of its future asbestos litigation defense costs. We are not able to determine how much NL will ultimately recover from these carriers for defense costs incurred, because of certain issues that arise regarding which defense costs qualify for reimbursement. While NL continues to seek additional insurance recoveries for lead pigment and asbestos litigation matters, we do not know the extent to which it will be successful in obtaining additional reimbursement for either defense costs or indemnity. In 2019, NL recognized $5.1 million in insurance recoveries which represented recovery of past and future litigation defense costs primarily related to a single insurance recovery settlement. In the fourth quarter of 2019 and the first quarter of 2020, Kronos recognized a gain of $2.6 million and $1.5 million, respectively, related to an insurance settlement for a property damage claim.

In the first quarter of 2018 we sold two parcels of land not used in our operating activities. We sold the first parcel for net proceeds of $18.9 million, and recognized a pre-tax gain on the sale of $11.9 million. We were required under our debt agreement with NERT to use a portion of the net proceeds received for the property to pay down our note balance and accordingly we made $2.2 million in principal payments on our debt, see Note 9. In addition, in 2018 NL sold excess property with a nominal book value for proceeds of $.6 million. In the third quarter of 2019, NL sold excess property for net proceeds of $4.6 million and recognized a pre-tax gain of $4.4 million. In the fourth quarter of 2019, NL sold its insurance and risk management business for proceeds of $3.25 million and recognized a pre-tax gain of $3.0 million on the sale. In the third quarter of 2020, BMI recognized a pre-tax gain of $4.0 million related to proceeds received associated with a prior land sale.
