During the year ended June 30, 2019, the Company entered into a CAD $127.0 million (or $97.0 million) commitment for telecommunications services over a two year period.

Outstanding Letters of Credit As of June 30, 2019, the Company had $8.5 million in outstanding letters of credit, which were primarily entered into in connection with various lease agreements.

Contingencies In the normal course of business, the Company is party to various outstanding legal proceedings, asserted and unasserted claims, and disputes. In the opinion of management, the ultimate disposition of these matters, both asserted and unasserted, will not have a material adverse effect on the Companys financial condition, results of operations, or cash flows. The Company accrues for losses related to contingencies when a loss from such claims is probable and the amount of loss can be reasonably estimated. In determining whether a loss from a claim is probable and the loss can be reasonably estimated, the Company reviews and evaluates its litigation and regulatory matters in light of potentially relevant factual and legal developments. If the Company determines an unfavorable outcome is not probable or the amount of loss cannot be reasonably estimated, the Company does not accrue for a potential litigation loss. In those situations, the Company discloses an estimate or range of the reasonably possible losses, if such estimates can be made. At this time, the Company does not believe that it is possible to estimate the reasonably possible losses or a range of reasonably possible losses related to the matters described below. Following the filing of the preliminary proxy statement on June 3, 2019, several complaints were filed against ZGH and its Board of Directors challenging the Merger. Four actions are pending in the United States District Court for the District of Delaware captioned Scarantino v. Zayo Group Holdings, Inc., et al., Case No. 1:19-cv-01068-RGA (D. Del.), Klein v. Zayo Group Holdings, Inc., et al., Case No. 1:19-cv-01085-RGA (D. Del.), Duggan v. Zayo Group Holdings, Inc., et al., Case No. 1:19-cv-01112-RGA (D. Del.), and Dixon v. Zayo Group Holdings, Inc., et al., Case No. 1:19-cv-01123-RGA (D. Del.); one action is pending in the United States District Court for the District of Colorado captioned Graves v. Zayo Group Holdings, Inc., et al., Case No. 1:19-cv-01747-KLM (D. Colo.); and one action is pending in the District Court of Boulder County, Colorado captioned Saroop v. Zayo Group Holdings, Inc., et al., Case No. 2019CV30601. The complaints generally allege, among other things, that ZGH and its directors disseminated an allegedly false and materially misleading proxy statement or that ZGHs Board of Directors breached their fiduciary duties in connection with the merger. The complaints seek, among other things, to enjoin the merger, a declaration that the proxy statement violated federal securities laws, unspecified damages, and an award of attorneys and experts fees. The defendants believes that each of these complaints are without merit and intend to vigorously defend against them. Three stockholders also filed complaints in the Delaware Court of Chancery pursuant to 8 Del. C. 220 seeking corporate books and records, captioned Teamsters Local 237 Additional Security Benefit Fund, et al. v. Zayo, C.A. No. 2019-0572-VCMR (July 25, 2019); Massachusetts Laborers' Annuity Fund v. Zayo Group Holdings, Inc., C.A. No. 2019-0573-VCMR; and Waterhouse v. Zayo Group Holdings, Inc., C.A.
