Supplemental Cash Flow Elements [Abstract]

Supplemental Cash Flow Information — Cash and cash equivalents include bank demand deposits and daily overnight reverse repurchase commitments of funds held in bank demand deposit accounts by certain subsidiaries, and are not considered part of the investment portfolio. The amount of reverse repurchase commitments held by these subsidiaries at June 30, 2021 and 2020, and December 31, 2020, were $90.5 million, $96.4 million, and $93.5 million, respectively. At June 30, 2021, $14.8 million of the restricted cash and cash equivalents on our consolidated balance sheets represents collateral held against unpaid premiums in the form of certificates of deposit, with the remainder representing cash restricted to pay flood claims under the National Flood Insurance Program’s “Write Your Own” program, for which certain subsidiaries are administrators.

During the six months ended June 30, 2021 and 2020, non-cash activity included declared but unpaid common share dividends of $58.5 million (see Note 9 – Dividends for further discussion) for both periods, and operating lease liabilities arising from obtaining right-of-use assets of $55.9 million and $23.9 million, respectively.

We paid the following in the respective periods:
