Revolving Credit Facility and 5.09% Senior Unsecured Notes--We have a $175,000 revolving credit facility with a group of banks, which will expire in November 2018 and permits borrowings, as defined, up to $175,000, including a letter of credit sublimit of $100,000 and a swing-line commitment of $15,000. Under certain circumstances, the amount available under the revolving credit facility may be increased to $210,000. The revolving credit facility contains certain affirmative and negative covenants customary for this type of facility and includes financial covenant ratios with respect to a maximum leverage ratio and a maximum balance sheet leverage ratio.

As of April 4, 2015, we had unused commitments under the facility approximating $48,664, with $126,336 committed, consisting of borrowings of $67,000 and issued letters of credit of $59,336. Borrowings outstanding bear interest, at Davey Tree’s option, of either (a) a base rate or (b) LIBOR plus a margin adjustment ranging from .75% to 1.50%--with the margin adjustments in both instances based on the Company's leverage ratio at the time of borrowing. The base rate is the greater of (i) the agent bank’s prime rate, (ii) LIBOR plus 1.5%, or (iii) the federal funds rate plus .5%. A commitment fee ranging from .10% to .25% is also required based on the average daily unborrowed commitment.

The $30,000 senior unsecured notes are due July 22, 2020 and were issued during July 2010 as 5.09% Senior Unsecured Notes, Series A (the "5.09% Senior Notes"), pursuant to a Master Note Purchase Agreement (the “Purchase Agreement”) between the Company and the purchasers of the 5.09% Senior Notes.

The 5.09% Senior Notes are equal in right of payment with our revolving credit facility and all other senior unsecured obligations of the Company. Interest is payable semiannually and five equal, annual principal payments commence on July 22, 2016 (the sixth anniversary of issuance). The Purchase Agreement contains customary events of default and covenants related to limitations on indebtedness and transactions with affiliates and the maintenance of certain financial ratios.
