Restricted Investments

Restricted investments include certain of the surplus assets that were transferred from the Company’s Pension Plan to a suspense account in the Company’s 401(k) Plan in December 2014. The Company has retained the risks and rewards of ownership of these assets; therefore, the assets held in the suspense account are included in the Company’s condensed consolidated financial statements until they are allocated to participants. The Company expenses the fair value of the assets at the time the assets are allocated to participants, which is expected to be allocated up to the next two years. During both the three months ended March 31, 2019 and 2018, the Company recorded an expense of $1.1 million, for the fair value of the assets, less expenses that were allocated to participants. Any gain or loss on these assets is reflected in the Company’s condensed consolidated statements of income and was less than a $0.1 million loss for the three months ended March 31, 2019 and 2018. Refer to Note 5. Financial Instruments and Fair Value Measurements.

Retained Interest Investments

The Company has a beneficial interest in certain bankruptcy-remote qualified SPEs used in the installment sale monetization of certain sales of timberlands in 2007 and 2008. The SPEs’ assets are not available to satisfy the Company’s liabilities or obligations and the liabilities of the SPEs are not the Company’s liabilities or obligations. Therefore, the SPEs’ assets and liabilities are not consolidated in the Company’s condensed consolidated financial statements as of March 31, 2019 and December 31, 2018. The Company’s continuing involvement with the SPEs is the receipt of the net interest payments and the remaining principal of approximately $16.8 million to be received at the end of the installment notes’ fifteen year maturity period, in 2022 through 2024. The Company has a beneficial or retained interest investment related to these SPEs of $11.6 million and $11.5 million as of March 31, 2019 and December 31, 2018, respectively, recorded in other assets on the Company’s condensed consolidated balance sheets.
