Advent Claymore Convertible Securities and Income Fund (NYSE:AVK) and Advent Claymore Convertible Securities and Income Fund II (NYSE:AGC) (each a “Fund” and together, the “Funds”) announced today the final results for each Fund’s tender offer for up to 15% of each Fund’s common shares (“Shares”) (the “Tender Offers”). The Tender Offers commenced on August 9, 2017 and expired on September 7, 2017.

A total of 8,775,224 Shares of AVK and 14,817,666 Shares of AGC were duly tendered and not withdrawn. Because the number of Shares exceeded 3,537,132 Shares of AVK and 4,829,532 Shares of AGC, the Tender Offers have been oversubscribed. Therefore, in accordance with the terms and conditions specified in the Tender Offers, each Fund will purchase Shares from all tendering shareholders on a pro rata basis, disregarding fractions. Accordingly, on a pro rata basis, approximately 40% of Shares of AVK and 33% of Shares of AGC for each shareholder who properly tendered Shares have been accepted for payment. The Funds expect to transmit payment to purchase the duly tendered and accepted Shares on or about September 13, 2017. The purchase price of properly tendered Shares is $16.9540 per Share of AVK and $6.4876 per Share of AGC, equal to 98% of each Fund’s net asset value per Share as of September 8, 2017 (the business day immediately following the expiration date of the Tender Offers). Shares that were tendered but not accepted for purchase and Shares that were not tendered will remain outstanding.
