As at December 31, 2013, the Company had three revolving credit facilities (or the Revolvers), which, as at such date provided for aggregate borrowings of up to $728.8 million, of which $148.2 million was undrawn. Interest payments are based on LIBOR plus margins, which at December 31, 2013, ranged between 0.45% and 0.60% (December 31, 2012: 0.45% and 0.60%). The total amount available under the Revolvers reduces by $94.0 million (2014), $120.9 million (2015), $89.1 million (2016), $395.9 million (2017) and $28.9 million thereafter. The Revolvers are collateralized by 21 of the Company’s vessels, together with other related security. One of the Revolvers requires that the Company’s applicable subsidiary maintain a minimum hull coverage ratio of 105% of the total outstanding balance for the facility period. As at December 31, 2013, this ratio was 114.3%. The vessel value used in this ratio is an appraised value prepared by the Company based on second-hand sale and purchase market data. A further delay in the recovery of the tanker market could negatively affect the ratio. In addition, one of the Revolvers requires the Company and certain of its subsidiaries to maintain a minimum liquidity (cash, cash equivalents and undrawn committed revolving credit lines with at least six months to maturity) of $35.0 million and at least 5.0% of the Company’s total debt. The remaining two Revolvers are guaranteed by Teekay and contain covenants that require Teekay to maintain the greater of free cash (cash and cash equivalents) of at least $100.0 million and an aggregate of free cash and undrawn committed revolving credit lines with at least six months to maturity of at least 7.5% of Teekay’s total consolidated debt which has recourse to Teekay. As at December 31, 2013, the Company and Teekay were in compliance with all their covenants in respect of the Revolvers.

As at December 31, 2013, the Company had three term loans outstanding, which totaled $164.0 million (December 31, 2012 - $180.2 million). Interest payments on the term loans are based on a combination of fixed and variable rates where fixed rates range from 4.06% to 4.90% and variable rates are based on LIBOR plus a margin. At December 31, 2013, the margins ranged from 0.30% to 1.0% (December 31, 2012 -0.30% to 1.0%). The term loan repayments are made in quarterly or semi-annual payments and two of the term loans have balloon or bullet repayments due at maturity in 2019 and 2021. The term loans are collateralized by first-priority mortgages on six of the Company’s vessels, together with certain other related security. Two of the term loans require that the Company’s subsidiaries maintain a minimum hull coverage ratio of 115% and 120%, respectively, of the total outstanding balance for the facility period. As at December 31, 2013 the loan to value ratios ranged from 146.7% to 388.9%. The vessel values used in these ratios are appraised values prepared by the Company based on second hand sale and purchase market data. A further delay in the recovery of the tanker market could negatively affect the ratios. The term loans are guaranteed by Teekay and contain covenants that require Teekay to maintain the greater of free cash (cash and cash equivalents) of at least $100.0 million and an aggregate of free cash and undrawn committed revolving credit lines with at least six months to maturity of at least 7.5% of Teekay’s total consolidated debt which has recourse to Teekay. As at December 31, 2013, the Company and Teekay were in compliance with all their covenants in respect of these term loans.

The weighted-average effective interest rate on the Company’s long-term debt as at December 31, 2013 was 1.1% (December 31, 2012 – 1.2%). This rate does not reflect the effect of the Company’s interest rate swap agreements (see Note 9).

The aggregate annual long-term principal repayments required to be made by the Company under the Revolvers and term loans subsequent to December 31, 2013 are $25.2 million (2014), $83.6 million (2015), $108.1 million (2016), $415.3 million (2017), $53.1 million (2018) and $59.3 million (thereafter).
