From time to time, we are party to various lawsuits, claims and other legal proceedings that arise in the ordinary course of our business. Excluding ordinary, routine litigation incidental to our business, we are not currently a party to any legal proceedings that we believe would reasonably be expected to have a materially adverse effect on our business, financial condition or results of operations.

We are subject to credit risk with respect to our tenant receivables and deferred rent receivables related to our tenant leases. Our tenants' ability to honor the terms of their respective leases remains dependent upon economic, regulatory and social factors. We seek to minimize our credit risk from our tenant leases by (i) targeting smaller, more affluent tenants, from a diverse mix of industries, (ii) performing credit evaluations of prospective tenants and (iii) obtaining security deposits or letters of credit from our tenants. For the three months ended March 31, 2020 and 2019, no tenant accounted for more than 10% of our total revenues.

All of our properties, including the properties of our consolidated JVs and unconsolidated Fund, are located in Los Angeles County, California and Honolulu, Hawaii, and we are therefore susceptible to adverse economic and regulatory developments, as well as natural disasters, in those markets.

We are subject to credit risk with respect to our interest rate swap counterparties that we use to manage the risk associated with our floating rate debt. We do not post or receive collateral with respect to our swap transactions. Our swap contracts do not provide for right of offset between derivative contracts. See Note 9 for the details of our interest rate contracts. We seek to minimize our credit risk by entering into agreements with a variety of high quality counterparties with investment grade ratings.

We have significant cash balances invested in a variety of short-term money market funds that are intended to preserve principal value and maintain a high degree of liquidity while providing current income. These investments are not insured against loss of principal and there is no guarantee that our investments in these funds will be redeemable at par value. We also have significant cash balances in bank accounts with high quality financial institutions with investment grade ratings. Interest bearing bank accounts at each U.S. banking institution are insured by the FDIC up to $250 thousand.

Conditional asset retirement obligations represent a legal obligation to perform an asset retirement activity in which the timing and/or method of settlement is conditional on a future event that may or may not be within our control. A liability for a conditional asset retirement obligation must be recorded if the fair value of the obligation can be reasonably estimated. Environmental site assessments have identified thirty-two buildings in our Consolidated Portfolio which contain asbestos, and would have to be removed in compliance with applicable environmental regulations if these properties are demolished or undergo major renovations.

As of March 31, 2020, the obligations to remove the asbestos from properties which are currently undergoing major renovations, or that we plan to renovate in the future, are not material to our consolidated financial statements. As of March 31, 2020, the obligations to remove the asbestos from our other properties have indeterminable settlement dates, and we are unable to reasonably estimate the fair value of the associated conditional asset retirement obligations.

In West Los Angeles, we are building a high-rise apartment building with 376 apartments. In downtown Honolulu, we are converting a 25 story, 490,000 square foot office tower into approximately 500 apartments. We expect the conversion to occur in phases over a number of years as the office space is vacated. As of March 31, 2020, we had an aggregate remaining contractual commitment for these and other development projects of approximately $211.4 million. As of March 31, 2020, we had an aggregate remaining contractual commitment for repositionings, capital expenditure projects and tenant improvements of approximately $25.5 million.

We have made certain environmental and other limited indemnities and guarantees covering customary non-recourse carve- outs for our unconsolidated Fund's debt. We have also guaranteed the related swap. Our Fund has agreed to indemnify us for any amounts that we would be required to pay under these agreements. As of March 31, 2020, all of the obligations under the related debt and swap agreements have been performed in accordance with the terms of those agreements. The table below summarizes our Fund's debt as of March 31, 2020. The amounts reflect 100%, not our pro-rata share, of the amounts related to our Fund:
