[1] As a practical expedient, the Company uses NAV (or its equivalent) to measure the fair value of its investments in the U.S. Insurance JV, the CREO JV and the CK Capital Value Fund. The U.S. Insurance JV invests in U.S. Dollar ("USD") denominated debt issued by small insurance and reinsurance companies. The CREO JV invests primarily in multi-family commercial real estate mortgage-backed loans. The CK Capital Value Fund invests primarily in office buildings in the Netherlands. According to ASC 820, these investments are not categorized within the valuation hierarchy.
